JM3KFADMXK15316112019 MAZDA CX-5Grand Touring

Cylinder block cracked on back side of engine. This crack leaks oil onto the exhaust manifold. Condition Confirmed by Mazda dealer. Oil burns on the exhaust filling the cabin with smoke impairing the driver. Also a high risk of combustion in the engine compartment Inspection report and pictures available. No sign or warning of issue. Crack happened on a daily drive to work. No engine lights noise or smell until head suddenly cracked causing a large oil leak. Mazda has an internal TSB 01-002/23 admitting that these cars in this year range have a manufacturer defect in the block

On May 11th I was driving my 2019 Mazda CX-5 with approximately 35,000 miles when my cabin filled with the smell of gasoline. The smell became overwhelming within minutes, causing concern for my safety and the safety of other drivers. I immediately drove to the closest auto repair/body shop for an emergency inspection. Upon inspection, the technicians discovered there was a "crack at rear cylinder head and leaking oil excessively. Oil is leaking on to hot exhaust manifold....car is not safe to drive since oil leak is excessive". I was advised that this must be a manufacturer defect as you should not see this issue at such low mileage. The vehicle was then towed to the nearest Mazda dealership/service center, where a cracked rear cylinder head was diagnosed and confirmed. I was informed that continued operation of the vehicle could have resulted in catastrophic engine failure, engine seizure, fire risk from leaking oil contacting hot engine components, or sudden loss of power while driving, creating an extremely dangerous driving situation. Prior to the failure, there were no major warning indicators other than the sudden strong fuel/oil smell. The issue occurred unexpectedly despite the vehicle being properly maintained and having low mileage for a major engine failure. I have been the sole owner. The vehicle is currently available for inspection upon request.

My 2019 Mazda CX-5 (equipped with the 2.5L naturally aspirated SkyActiv-G engine with cylinder deactivation) has experienced a severe structural failure resulting in a cracked engine cylinder head. This casting defect allows pressurized motor oil to leak continuously from the cylinder head down onto the hot engine block and nearby exhaust components. This has led to the following severe safety risks: engine oil is leaking onto the exhaust manifold and creates an extreme risk of engine compartment fire when the vehicle is in motion; sudden loss of oil pressure or complete structural failure of the cylinder head can cause the engine to stall or seize unexpectedly without warning, completely disabling the vehicle in live traffic and creating an imminent crash hazard; and dropping oil levels and leaking fluids burning against the engine produce strong smoke and chemical odors that enter the cabin, which can cause driver distraction and severely limiting visibility if smoke escapes through the hood. We are also inhaling these odors. Mazda is fully aware of this structural engine defect and has detailed it internally under Technical Service Bulletin TSB #SA-031-21 (as well as related TSBs for oil seepage/leaks on these cylinder heads). Despite acknowledging the manufacturing flaw, Mazda has failed to issue a safety recall for this dangerous fire and stalling hazard, forcing consumers to drive unsafe vehicles or pay thousands of dollars out of pocket for a known defect. The vehicle currently has 62,317 miles. The crack and oil leak were officially diagnosed by the Carlsbad Mazda dealership service department on 5/26/26. I am requesting that the NHTSA launch a formal safety defect investigation into Mazda 2.5L cylinder head cracking to force a safety recall before this defect leads to a fatal fire or highway accident.

The contact owns a 2019 Mazda CX-5. The contact stated that on several occasions while driving at approximately 10 MPH, the infotainment system changed settings, made phone calls, and changed the distance for automatic braking, which caused the vehicle's brakes to be applied inadvertently while another vehicle was behind them. The vehicle was taken to a dealer where it was diagnosed that the infotainment screen was defective and needed to be replaced. The vehicle was not repaired. The failure mileage was approximately 45,000.

The contact owns a 2019 Mazda CX-5. The contact stated while driving at an undisclosed speed, the instrument panel independently switched between features. The contact stated that the failure was persistent. The vehicle was taken to the dealer, however the vehicle was not diagnosed. The contact was requested to pay a diagnostic fee, the contact declined. In addition, the contact was informed that the failure was a known failure with the vehicle. The manufacturer was not made aware of the failure. The failure mileage was approximately 35,000.

This 2019 Mazda CX 5 is experiencing a crack in the oil cylinder. THis appears to be connected to: There is no official, broad NHTSA recall for cracked oil cylinders in the 2019 Mazda CX-5, but Mazda has issued a Technical Service Bulletin (TSB #SA-031-21) to address this known issue. It affects certain 2018–2021 CX-5s, particularly those with 2.5L engines, where a cracked cylinder head leaks coolant or oil. If this is a known issue with this vehicle, why has a recall not been addressed?

My car has an issue officially diagnosed by a reputable mechanic that matches the claim of the former TSB SA-058/20 that was changed and clarified through the now existing TSB SA-031/21. My car has a cracked cylinder head. This is the non turbo engine but it does have cylinder deactivation which his believed to be a culprit. The cracking is known to be caused by a manufacturing defect. There is an existing class action lawsuit regarding the turbo versions. There are complexities as to wh this lawsuit is on behalf of the turbo engines, and not the non turbo engines, however the same problems are well documented and widely acknowledged throughout hundreds if not more instances of people online and by Mazda's acknowledgment of the problem through the TSB's. This put me at great safety risk. I was driving north bound right beside semi trucks and busy traffic at speed limits of 70 mph when my engine started smoking. I was able to pull over and get it to a nearby mechanic. They officially diagnosed the vehicle w the cracked cylinder head matching the aforementioned TSBs. Mazda denied my goodwill case, even though it was made without complete information on my situation and car, despite my best attempts to get to the one representing my case with the dealership(I tried to reach him for 2 days with no success). Getting a repair from Mazda dealerships was inconvenient for my location and schedule, but I've always had my vehicle properly serviced. Mazda said this repair would cost near $7500. A mechanic quoted me at least the amount of $5500.

I own a 2019 Mazda CX-5 with approximately 36,000 miles. The vehicle developed a strong burning oil smell while driving, particularly through the HVAC/vent system. I initially reported the odor to a Mazda dealership, but no issue was identified. Approximately two months later, the smell returned and worsened. The vehicle was later diagnosed by a Mazda dealership with an oil leak originating from the cylinder head near the exhaust manifold. According to the repair documentation, oil was accumulating on the exhaust due to seepage from the cylinder head. The repair required full cylinder head replacement. This created significant safety concerns because leaking oil was contacting hot engine/exhaust components while the vehicle was being operated. Burning fumes entered the passenger cabin through the vents while driving. I was concerned about the risk of fire, smoke inhalation, sudden oil loss, and possible engine failure while on the road. There were no warning lights prior to the failure. The primary symptom was the persistent burning smell. The dealership replaced the cylinder head. The original repair estimate was approximately $6,000. Mazda later provided partial goodwill assistance, but I was still required to pay approximately $2,500 out of pocket. After researching this issue further, I found numerous similar NHTSA complaints involving 2019 Mazda CX-5 vehicles experiencing cylinder head leaks/cracking near the exhaust manifold, burning smells, smoke or fumes entering the cabin, and major engine repairs at relatively low mileage. Mazda has acknowledged similar cylinder head concerns in CSP11 and TSB 01-002/23 for certain VIN ranges but denied coverage for my vehicle because the leak involved oil rather than coolant and because my VIN was outside the covered range. I am requesting that NHTSA investigate whether this represents a broader cylinder head defect affecting additional 2019 Mazda CX-5 vehicles outside the currently covered VIN range.

Cylinder head is cracked and leaking oil. The Cylinder head has an active warranty extension but Mazda only applies this to coolant leaks and not oil leaks. The root cause is a casting defect along with a exhaust manifold design issue that imparts undue stress onto the cylinder head causing cracks. The limitation of the warranty to the type of fluid that leaks rather than the failure due to design issues with the exhaust manifold and cylinder head does not make sense given that both components have been redesigned due to the prevalance of both coolant and oil leaks from cylinder head cracks. Problem has been confirmed by Quality Mazda Service departmetn on April 4, 2026 but no warranty coverage extended to repair the failure due to the fluid leak being oil and not coolant. No warnings or messages given prior to leaks. Leaks began at roughly 76,400 miles.

The cylinder head cracked, causing a coolant leak, which then lead to the car overheating. My car was taken into Mazda dealership because there is a warranty extension for this specific part CSP111. The Mazda dealership, corporate, and warranty department all stated the known widespread defect cracked cylinder head will not be replaced on their behalf due to an overheating code. Mazda is using a symptom as an excuse to the problem. Due to the overheating code, Mazda recommended replacing the whole engine for $10,000 with 20 hours of labor. This defect part and Mazda’s unwillingness to provide a proper solution caused my car engine to fail, posing a safety risk. No symptoms other than low coolant were present, which my car was then parked, not driven, and towed to the dealership, in hopes the warranty would be honored.

A Mazda Dealership should me a Mazda cx5 2019, in 2023, at nearly 38k miles, right about where many have reported a cracked cylinder issue due to a manufacturing issue in age, and in milage. There is a lawsuit ongoing regarding the turbo version, however many reporting the same issue in the non turbo versions. My engine started smoking while on the highway causing a highly dangerous scenario to which I was barely able to make it to a mechanic where all the oil spilled out upon arrival. I got a diagnostic from a reputable mechanic confirming the cracked cylinder.

My wife's vehicle has a "Infotainment screen" (dashboard touch screen). There is a class action suit (CSP13d dealer letter) for issues regarding the screen performing tasks (Ghost screening touch) on its own. In lieu of a Mazda vehicle mass recall, they agreed to "FIX" the issue with a software update and replace the CMU Module of the vehicle to rectify this issue. I am here to report / advise you that MANY Mazda owners are NOT happy and have taken it upon themselves to disconnect these screens and do other "work around self repairs (removing/ disabling the unit) in order to fix the issues that occur. I have directly contacted Mazda in regards to my issues and they stat they can ONLY do what was advised on the court ordered settlement and NOTHING more to fix the issue. I want to advise you first hand, their FIX for this issue does NOT fix the problems. In fact, it is making it much worse! NOW my wife's vehicle is operating this screen by itself, WHILE driving, creating a MAJOR distraction. This "Ghost Touching" is actually going into the braking system settings and trying to change/ alter them AS she is driving! A MAJOR SAFETY ISSUE. She has had to, on several occasions, pull over /off the road, shut down the vehicle and try to "reset" what has occurred and check her system for ANY altered setting..if possible. As a retired Police Officer, I can tell you first had that if we ever encountered such thing/ safety issues reported by drivers, we would NOT allow them to travel any further with the vehicle and have it safely towed to a dealer or mechanic for repair. For their safety as well as the rest of the publics safety!! Mazda has refused to fully fix this issue and you can even see on numerous social media posts of MANY others reporting similar issues, disabling their devices on their own and doing other work arounds to mute or disable their devices totally. I Implore you to do a FULL RECALL of ALL affected vehicles to fix the problem ASAP!

Today I was using this vehicle and the cars my pocket got stuck in between the car seat dial for the movement of the car seat and the door and as I was in reverse the car seat started to move and pushed me all the way to the steering wheel as I was in a drive situation mode so I had to break it all off disconnected and everything

Engine has a crack in the head, well under 100,000 miles. It's a known defect but Mazda refuses to do anything about it. It is currently a very expensive paperweight sitting under our carport.

My 2019 Mazda CX-5 with approximately 78,000 miles developed a sudden major engine oil leak. The Mazda dealership diagnosed the issue as a cracked cylinder head and quoted approximately $5,600 for repair. The vehicle was properly maintained and this failure occurred without warning. A cylinder head failure at this mileage appears premature and may represent a defect. The oil leak created a large puddle under the vehicle and could pose a potential safety hazard due to loss of engine oil.

2019 Mazda CX5 has a cracked cylinder head. This is causing oil to leak out. The oil is leaking out onto the exhaust manifold which is causing the manifold to smoke and has the possibility to catch fire. Mazda is aware of this issue and issued CSP 11( customer service program). This does not cover the oil leak, only coolant leak. Several Class Action Lawsuits have been filed. Local Mazda dealership has inspected the car and confirmed the issue. The issue occurred suddenly with no warning. Again, Mazda is aware of this issue but has failed to issue a recall or service program to fix it, this is a dangerous issue as it can lead to a fire with the oil leaking onto the exhaust manifold.

I am reporting a premature engine failure on my 2019 Mazda CX-5 with approximately 55,000 miles. The vehicle developed a significant engine oil leak that was diagnosed by a repair facility as a casting failure in the cylinder head behind the timing cover. Due to the location of the leak and the nature of the defect, the entire cylinder head assembly had to be replaced. The total repair cost was $5,262.32, which I paid out of pocket. The repair documentation indicates that Mazda has issued a Technical Service Bulletin addressing this condition, but there is currently no recall or warranty extension covering the issue for my vehicle. A cylinder head casting failure at such low mileage appears premature and not consistent with normal wear and tear on a properly maintained engine. An engine oil leak of this nature could potentially create safety risks, including oil contamination of engine components or the possibility of oil leaking onto hot engine parts. Because this issue appears to be documented by Mazda through technical service guidance and has resulted in a costly major engine repair at relatively low mileage, I believe it should be investigated to determine whether a broader manufacturing defect exists that could affect other vehicles. I am submitting this complaint so that the issue is documented and can be evaluated for potential safety concerns or a future recall if similar failures are occurring in other vehicles.

My VIN indicates the 2.5L non-turbo SKYACTIV engine. Many 2019 CX-5 Touring models with this engine used cylinder deactivation, which is the version that has had some cylinder head cracking complaints. The engine type has documented failures my mileage (96k) is not extremely high for an engine The repair cost is very high (5,500) Mazda is refusing to help me out of goodwill assistance and ive only had the car for a year. They know this is a problem and fixed it for the turbos but not the non turbos! This is ridiculous, i expected a car to last more than 96k miles this can cause a fire or a stall and can cause a crash

My 2019 Mazda CX-5 started to smoke from the engine and I could smell oil burning. My car was due for an oil change so I brough it to a mechanic. After a diagnostic, they determined that there was a major oil leak and that the cylinder head was cracked and suggested I take it to the dealership. I did and they confirmed that there was a cracked cylinder head causing the massive oil leak. The technician even said in a video sent to me that the oil is leaking "in the same place as the others". I was then quoted 5,960.75 to make this repair. I did research and found that this is a manufacturing defect that is long known to Mazda. There is a TSB and a CPS that extends the warranty for this issue but only for turbo engines, not my non-turbo engine. My car is 2 years past the warranty but I only have 32K miles on it. I asked if Mazda could cover all or some of the cost since it is a defect, not caused by anything I did or didn't do. I was then told that because I didn't take my car there regularly for service, that they wouldn't cover it. I regularly took my car in for oil changes and other maintenance to a local shop as the nearest dealership was almost 30 miles away so it was very inconvenient. It's outrageous that Mazda won't issue a recall or extend the warranty for the same issue in the non-turbo engines. Asking me to pay 6K for a defect they caused is unconscionable.

The head on the 2.4L engine of the 2019 Mazda CX5 has shown a manufacturing defect that Mazda has addressed in certain models, but not all of the models with this engine. This leaves a large amount of vehicle owners with the financial liability to pay out of pocket for Mazda's engineering and manufacturing defect that they know about. The oil leaks onto the exhaust manifold creating a fire hazard. When driving our car, we cannot use outside air on the vents, A/C because the intake pulls in smoke coming from the engine compartment. I brought the car in today to Mazda and was denied any help in the repair, I am continuing with Mazda corporate to try and reach a resolution. Currently this will be roughly a $7000 repair. I do not have an estimate yet from the dealership.

I purchased a 2019 Mazda CX-5 (As is) on July 20, 2015. On September 11, 2025, as I was traveling on a three lane highway. I attempted to pass another vehicle. As I was attempting to go around the vehicle, my Mazda suddenly began braking and quickly losing acceleration. The speed limit on the highway was 70 mph. I estimated my speed at the time was between 70 and 75 mph as I attempted to pass. Pressing on the accelerator pedal did nothing. I had to try and very carefully steer the car to the right hand side of the road while trying to avoid oncoming traffic approaching from behind. When I finally got the car off the road, this is when I noticed that the car had stalled. The car started right back up and I continued to my appointment. The "radar cruise control" was activated at the time of the incident. On September 15, 2025, I contacted the dealer where the car was purchased and explained what happened. I was asked to bring the car in that same day. The car was supposedly looked over and connected to the Service Dept.'s computer to see if any error sign appeared. Nothing showed up. I service technician was then asked to ride with me to see if the car would replicated the same stalling as it has previously done. We could not get the car to stall as it had previously done. Before leaving, a salesman asked me if I wanted him to explain the "radar cruise control" to me some more. I agreed. The salesman then proceeded to tell me that "the car did not stall, it was simply braking from the activation of the radar cruise control". Being an experienced driver, I told the salesman that the car had stalled as evidenced by the fact that I had to restart it. The situation was not resolved to my satisfaction, but no other offers were made by the dealer. I requested additional diagnostic work to be done, but the dealer refused to cooperate. I did take the car to another Mazda dealer, but could get no offer but to connect the car to their computer.

My fuel pump burned out after only 60k miles.... very expensive repair. Mazda said the problem was only with the early 2019 models so mine wasn't included yet my fuel pump did exactly what the ones included in the recall did, but I was left with over $1700 repair bill to replace the fuel pump. Obviously the "improved design" used in the second half of the year isn't really improved, and I've never had to replace a fuel pump on a vehicle with so few miles on it. We were sitting idle waiting for food at a restaurant and the engine just died and we were unable to re-start the vehicle. No issues prior to this, always kept fuel at least 1/4 tank or more full and no engine warning lights until AFTER the engine died.

The engine cylinder head cracked and is leaking engine oil. This component is available for inspection at Liberty Mazda or by an independent certified mechanic upon request. The cracked cylinder head caused significant engine oil leakage, which created the following safety risks: Sudden loss of engine power or stalling while driving Smoke emission from the engine bay Potential fire hazard if leaking oil contacted hot engine components These conditions placed both the driver, passengers, and others on the road at risk. The cracked cylinder head and associated oil leak were diagnosed and confirmed by Liberty Mazda, the authorized dealership that performed prior repairs on this vehicle. The dealership documented the issue and provided a repair estimate of approximately $5,400. No independent service center has inspected the vehicle at this time. The vehicle and cylinder head have only been inspected by Liberty Mazda. Mazda Corporate has not physically inspected the vehicle, but all service records and documentation of prior repairs have been submitted to them during the warranty dispute process. There has been no inspection by police, insurance representatives, or other third parties May 2025: The vehicle intermittently struggled to accelerate. At that time, no dashboard warning lamps illuminated, and the dealership initially reported no issues. June 2025: Following the timing cover repair, the vehicle experienced engine oil leakage due to incorrect sealant installation, which was documented. February 10, 2026: The dealership repaired the oil pan seal and replaced the sealant, refilling engine oil. February 14–15, 2026: Approximately four to five days after the February 10 service, the cylinder head cracked, causing a significant oil leak. All symptoms and related service events are documented in Liberty Mazda’s service records.

The touchscreen digitizer on the Mazda Connect infotainment system has developed a known defect causing constant phantom/ghost touch inputs. The screen registers random touches without any physical contact, causing the system to navigate through menus, change vehicle settings (including safety-related settings such as blind spot monitoring and heads-up display), exit navigation mid-route, change radio stations, and initiate phone calls to contacts without driver input while connected to Apple CarPlay. This is a significant driver distraction and safety hazard. When the system begins making random inputs, the driver must divert attention from the road to attempt to regain control of the infotainment system or end unintended phone calls. The issue occurs most frequently when the vehicle is stopped or at low speeds but also affects the system while driving. This is a well-documented hardware defect affecting 2017-2020 CX-5 models, acknowledged by Mazda under TSB 09-003/22. The cause is a failing touchscreen digitizer, not a software issue. Mazda has not issued a formal recall despite widespread reports. The component is available for inspection upon request. The vehicle has not yet been inspected by a dealer for this specific issue. No warning lamps or messages preceded the failure — the phantom touch inputs developed gradually and have worsened to the point that the infotainment system is nearly unusable. Current mileage is approximately 60,000-80,000 miles.

The vehicle's cylinder head has developed a structural crack at on the casting, a known manufacturing defect identified by the manufacturer in Service Advisory SA-037/23. This failure is causing pressurized engine oil to leak directly onto the hot exhaust manifold while the vehicle is in operation. The leaking oil is pooling on high-temperature exhaust components, creating a significant risk of fire while driving. The leak generates heavy smoke and noxious burning oil fumes that are entering the passenger cabin through the HVAC system, causing respiratory issues

Oil is leaking from the front timing chain cover and the vehicle is available for inspection upon request. The issue was caught early enough before it was an acute safety issue, however this issue can cause smoke while driving and cause the vehicle to lose function while driving, endangering those in and around the vehicle in motion. The vehicle only has 35,000 miles on it, has been confirmed and documented by an independent service center, and this is a widespread well-known issue - the service center has had three vehicles in this week with the same exact issue, and Mazda issued a technical service bulletin detailing the issue and stating the root cause is a lack of sufficient sealant applied during manufacturing. The vehicle has not yet been inspected by the manufacturer, police, or insurance representatives - only a service center. There were no warning lamps or messages of the problem prior to failure - I was lucky to have this caught during a routine inspection.

The vehicle has suffered a crack of the Cylinder Head Assembly which leads to engine oil leaking onto hot exhaust and fire hazard. This defect is officially documented by the manufacturer in Service Alert SA-031/21, which identifies a trend of aluminum heads cracking and leaking pressurized oil directly onto the hot exhaust manifold. Although Mazda has issued a 10-year/120,000-mile warranty extension (Program CSP11) for the exact same casting failure in its Turbo-equipped models, it has refused to provide similar "Goodwill" relief for my vehicle, despite it suffering from the identical engineering flaw. Mazda’s refusal to cover a verified latent manufacturing defect that poses a significant fire hazard is arbitrary and unfair. I am requesting that Mazda North American Operations provide full reimbursement for the $6,788.51 repair

I am being told there is a crack in the cylinder head that is a known issue for these vehicles. I have done some research online and it says that they installed defective cylinders in vehicles that were made between the years 2018-2020 leaving vehicle owners to pay thousands of dollars out of pocket due to a manufacturing defect. My car was smoking and smelling like something burnt even inside the car causing the driver to inhale those fumes, I took it to the shop and it turns out that the cylinder head is cracked and leaking the oil.

The vehicle is experiencing a “ghost touch” malfunction within the infotainment system, wherein the touchscreen registers unintended inputs. As a result, the system intermittently initiates phone calls, changes radio stations, and alters other settings without driver interaction. This erratic behavior is highly distracting and presents a potential safety concern while the vehicle is in operation.

1. What component failed, and is it available for inspection? Component: The Engine Cylinder Head. The Failure: The cylinder head failed due to a structural crack caused by overtightened bolts (manufacturing defect), resulting in an engine oil leak. Confirmation: The defect is confirmed and resolved. Wayne Mazda (NJ) acknowledged the failure and replaced the cylinder head under the CPO Warranty last month. The issue has not returned since the replacement, proving this was indeed a hardware defect. 2. How was your safety put at risk? Fire Hazard: Before the repair, for a duration of one year, the vehicle leaked engine oil onto the hot exhaust manifold, creating a persistent fire risk. Toxic Exposure: My family and I were forced to inhale burning oil fumes inside the cabin for months due to the dealer's delayed diagnosis. This posed a significant health hazard. 3. Has the problem been reproduced or confirmed? Yes. The defect was initially identified by independent service centers (when the dealer failed to find it) and was ultimately verified and repaired by Wayne Mazda. The fact that the dealer performed the repair under warranty is an admission of the manufacturing defect. 4. Financial Damages & Request for Reimbursement: Since Mazda has admitted liability by fixing the vehicle, I request reimbursement for the losses incurred due to the delay in diagnosis: $2,000+ in Independent Repairs: Because Wayne Mazda initially failed to diagnose this warrantable defect, I was forced to pay independent shops to diagnose and attempt to fix the oil leak to keep the vehicle safe. These costs were a direct result of the dealer's inability to identify the manufacturing defect. $159.29 in Uber Fees: Mazda failed to provide a loaner vehicle during the major powertrain repair, forcing me to pay for my own transportation. Conclusion: I am filing this report to: Document this safety defect (Overtightened Cylinder Head Bolt / Oil Leak) for NHTSA records, as it poses a fire

Drove 39 miles, around ~55 minutes. Parked the car, realized that I parked a little too far from the spot, car just stalled while rolling. Pressed accelerator, nothing. Turned off the car, tried to start again, it cranked but didn't start. Had to tow it to the nearest mechanic (total of ~2 hrs until my car got picked up and dropped off), mechanic calls me and tells me my car started fine. I'm thinking it could be 5321K recall but not sure as my VIN is not in the recall nor did I get any recall notice. What component or system failed or malfunctioned, and is it available for inspection upon request? - No idea. How was your safety or the safety of others put at risk? - Got stranded for hours in the parking lot. Has the problem been reproduced or confirmed by a dealer or independent service center? - No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? - No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? - Yes, fuel cap like icon and check engine light were on when trying to start the car after it stalled. The car would crank but not start.

On 12/10/25, my 2019 CX5 NA had major oil leak after smelling a burning smell for a few days. Took it into local mechanic and he couldn’t find the leak, did an engine wash and additional testing before identifying a crack in the cylinder head; the leak was coming from the exhaust manifold. There was oil all over the engine and the underbelly of the vehicle; according to the mechanic, I was lucky the car didn’t start on fire with the amount of oil. I was informed that this is a common problem with the turbos and the NAs but the extended warranty only included the turbo engines. Contacted Mazda customer experience and set up an appointment. Vehicle went to the Mazda dealership on 12/15 and it was confirmed that there was a crack in the cylinder head and received an estimate of $11,000 needed for repairs. $7000 of that was for a new cylinder head. This was after an independent mechanic inspected my vehicle and stated everything looked good besides the main issue and needing new rear breaks in the next few months. 12/15-contacted Mazda customer experience and and case file was opened. 12/16-contacted customer experience back due to not receiving a call and received the name and extension of the assigned case manager. 12/17- still had not received a call back and left voicemail for case manager. Requested a call back to myself and the dealership; received a call back a few hours later and I was never asked what happened but was informed that Mazda corporate could not help me due to the warranty being expired. I am now required to pay over $250 to the dealership for an inspection of the vehicle I never requested. There were initially no warning signs but then the low oil light came on after 3 days of smelling something burning.

The 2019 CX-5 AWD with the 2.5L NA engine (with Cylinder Deactivation) has an engine oil leak coming from the cylinder head area. The Mazda dealer confirmed the leak source and found burnt oil on the exhaust. The component is available for inspection. The leak location and symptoms are consistent with the known porous/cracked cylinder-head defect documented in this engine family. Full confirmation requires teardown. In early Dec 2025, a burning oil smell began, then thick white smoke came from under the hood while driving and after stopping. This created an immediate fire risk, and rapid oil loss could cause sudden engine failure or stall in traffic. The issue was inspected and confirmed by an independent mechanic, who noted the leak could only be traced after removing the exhaust manifold. The Mazda dealership then inspected it and confirmed the leak source at the cylinder-head area and the burnt oil residue. The problem has been reproduced and confirmed by both the independent mechanic and the Mazda dealer. No warning lights or messages appeared prior to the smoke. Mazda has an extended warranty program for the same cylinder-head defect on the Turbo engine, but no equivalent coverage exists for the NA engine, despite the identical safety risks.

While driving a short distance, my engine overheated and there was a strong burning smell. The cylinder head was cracked, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk and should not be driven. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical problems. Mazda should be held responsible for this safety issue. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their warranty period, placing costly repairs and potentially life-threatening situations on their customers. The repair is replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected customers with no support for a known manufacturing flaw. I urge NHTSA to investigate this recurring engine defect in non-turbo 2019–2020 Mazda CX-5 models and encourage Mazda to offer equal reimbursement.

Summary of Issue: The infotainment system in my 2019 Mazda CX-5 has been malfunctioning for a long period of time, and the issue has now escalated to the point where the system is unsafe and distracting while driving. Details: The infotainment screen intermittently “ghosts” and activates functions on its own—clicking through menus, changing settings, and moving erratically without any driver input. The system has also frozen and rebooted while the vehicle is in motion. This creates a serious distraction and safety concern. I previously reported this issue to the dealership, where they attempted a reset and told me to come back if the problem returned. The issue persisted and worsened. I recently returned, and the dealership diagnosed a communication failure between the CMU and the infotainment screen. However, they cannot identify any cause, and the screen itself has no physical damage and has never been struck. Mazda has declined to cover this under warranty, even though this appears to be an internal failure of components that should not fail at this mileage. Additionally, infotainment failures in Mazda vehicles have been the subject of prior complaints and service bulletins. Safety Concern: The malfunction causes the screen to operate unpredictably while driving, which distracts from the road and creates a risk of an accident. Because the system controls access to vehicle settings, Bluetooth, audio, navigation, and backup camera interfaces, the failure presents a potential safety defect. Requested Action: I am requesting that NHTSA investigate whether this infotainment / CMU communication failure is a broader defect affecting 2019 Mazda CX-5 vehicles, as dealerships cannot identify the cause and the failure poses a clear distraction hazard.

Question 1 - What component or system failed or malfunctioned, and is it available for inspection upon request? Answer 1 - The Engine Cylinder Head. The cylinder head developed a crack, causing a significant oil leak. The car is currently at the dealership but is available for inspection upon request. Question 2 - How was your safety or the safety of others put at risk? Answer 2 - The defective cylinder head is leaking engine oil directly onto hot exhaust components. This creates an immediate risk of engine fire and causes smoke to enter the vehicle cabin, impairing visibility and driver health. Additionally, the loss of engine fluids creates a risk of sudden engine failure or stalling at highway speeds. Question 3 - Has the problem been reproduced or confirmed by a dealer or independent service center Answer 3 - Yes. The vehicle was diagnosed by an authorized Mazda dealership. They confirmed the cylinder head is cracked and requires replacement. The dealership acknowledged the failure and offered a partial repair discount, confirming their diagnosis of the defect. Question 4 - Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? Answer 4 - Yes. The vehicle has been inspected by an authorized Mazda dealership technician acting as a representative for the manufacturer. I have also escalated the issue to Mazda Corporate (case number can be provided upon request), who reviewed the dealership's findings but refused to cover the full repair cost. Question 5 - Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Answer 5 - I noticed an oil leak on my driveway. I noticed it and brought it in to be looked at the first week of November 2025.

What component or system failed: The cylinder head failed due to cracking around the exhaust manifold, resulting in exhaust and coolant leakage. My independent mechanic and the Mazda dealer both confirmed this was the source of the burning smell and engine risk. The failed parts are currently in the possession of the Mazda dealership and available for inspection upon request. Safety risk: The failure created a strong burning rubber smell inside and outside the vehicle while driving. My mechanic advised this type of leak could lead to engine overheating, sudden power loss, or potential fire risk if not caught early. I frequently transport children in the vehicle, and the unexpected engine damage posed a significant safety concern. Has the problem been reproduced or confirmed: Yes. The issue was first diagnosed by an independent, certified mechanic and then confirmed by the Mazda dealership, who determined the cylinder head had to be replaced due to premature cracking and leakage. Has the vehicle/component been inspected: Yes. The vehicle has been fully inspected by an independent mechanic and the Mazda dealership service department. The dealership stated the failed cylinder head will be sent to Mazda for engineering review. Were there any warning lamps or symptoms before failure: There were no warning lights or error messages prior to the failure - which is alarming. The only initial symptom was a strong burning rubber smell that began shortly before the diagnosis. No overheating warnings appeared on the dash before the problem was confirmed. Additional context: The vehicle has 40,000 miles, has been fully maintained according to schedule, and is garage-kept. The Mazda service department acknowledged this failure is unusual and premature. Mazda has issued prior Technical Service Bulletins and warranty extensions for similar cylinder head/manifold cracking issues on the 2.5L turbo engine, but no program exists for the non-turbo engine, despite identical symptoms.

The Cyclinder Head cracked. This could cause the engine to fail, and leaving the driver on the highway or other unsafe locations of travel. The certified repair shop along with the insurance adjuster advised it was a manufacturing defect. The warning sign was an oil burning smell inside the vehicle while stationary and inside the garage.

Timing chain gasket leak, causing oil to go everywhere and smoking could cause a fire

Confirmed cracked cylinder by dealership, led to dumping of oil while vehicle was in motion on the highway. Vehicle/engine could have caught fire at any moment. There were no engine warnings that appeared on the dash. This is consistent with other CX-5 complaints on NHTSA. Vehicle had 55,000 miles on it at time of incident, and needed $8,000 worth of repair. Please recall!!

In August 2025, we brought our Mazda CX-5 (non-turbo engine) to a Mazda service center and paid nearly $3,000 for repairs, including replacement of belts and other related service. Despite this, we continued to experience a burning smell from the vehicle. Shortly thereafter, the problem escalated — the burning smell persisted and smoke began to appear. Mazda is now demanding an additional $4,500 to replace a cracked cylinder head. This defect must have been present when the car was serviced in August, and the initial repairs failed to identify or correct it. While there is an NHTSA Technical Service Bulletin for the turbo version of this engine, there are numerous complaints online about the same defect in the non-turbo model, which is what we own. This indicates that the problem is not isolated. Mazda should be held responsible for this safety issue. A cracked cylinder head that leads to burning smells and smoke is a serious hazard that could cause engine failure or even fire. Consumers should not be forced to spend thousands of dollars on repairs for what appears to be a widespread defect and when our vehicle has only $50k miles and it should last for the life of the vehicle.

Cracked/Leaking Cylinder Head on my 2019 Mazda CX5. It is understood that Mazda has extended warranty for the Turbo Model (CSP11) of this car, but not the standard engine, even though they both are displaying the same issue in many 2019 CX5s. Quoted at $6000 for a vehicle under 90K Miles. Issue needs to be escalated.

The contact owns a 2019 Mazda CX-5. The contact stated that while driving 30 MPH with a toddler occupying the rear seat, the contact noticed smoke and an abnormal burning rubber odor coming through the vents. The contact pulled into a gas station and then pulled into a nail salon parking lot. There was no warning light illuminated. The contact was able to drive to the residence, where an independent mechanic inspected the vehicle and found an oil leak, and the mechanic diagnosed that the cylinder head had cracked. The vehicle was taken to the dealer. The dealer informed the contact that the repair could not be covered under an unknown Extended Warranty because of the type of engine. The manufacturer was notified of the failure and informed the contact that the repair could not be covered under Goodwill assistance because the oil changes had not been mainly performed by the dealer. The vehicle was not repaired. The failure mileage was approximately 83,000.

Cracked Cylinder Head.

Dealership service department found a cracked cylinder head. This issue has been reported to NHTSA by Mazda. The car is being serviced and this issue was found. I’m attaching photos and also report from dealership l.

Timing cover oil leak. This is the same issue reported in technical bulletin #01-006/23 issued on 04/26/2023. There is oil leaking and the engine is smoking. No engine warning lights or other messages appeared. My car is a 2019 mazda CX-5 and has 31,954 miles. This problem has been confirmed by both an independent mechanic and the dealer service center. On 08/22/2025, I took my vehicle to dealer service for the repair. I also submitted a ticket to Mazda care for review of the case.

My vehicle was damaged by an as yet determined electrical fire seemingly having originated in the passenger door speaker components.

While operating the vehicle it will randomly start changing infotainment system settings. The radio station settings change, navigation maps will pop up and unprompted phone calls will be initiated. Each action is followed by a “beep.” Very distracting and requires actions that take focus away from operating the vehicle.

When accelerating, the transmission feels jerky/stutters. The check engine light and traction control light are illuminated and on the instrument cluster the messages: "Forward Smart City Brake Support Malfunction", "Smart Brake System Malfunction" and "Front Radar Sensor System Malfunction" appear. The vehicle acts like it doesn't know which gear it should be in, it'll buck pretty hard and then it refuses to accelerate...it feels like it's in a "limp mode". A previous driver of the vehicle complained and said that it actually stalled in traffic on the highway and was of course difficult to steer due to loss of power. I took it to a dealership and they came up with a laundry list of things to fix...most of which wouldn't have any bearing on this issue. I did have the serpentine belt replaced and the belt tensioner replaced due to wear on the belt and loose tension. On 7/16/25, I scanned the vehicle with a code reader, the codes P0301 and P0506 appeared. P0301 is a generic "Cylinder 1 Misfire Detected" message and P0506 is a generic "IAC system RPM Lower Than Expected. The vehicle was taken to a shop where the spark plugs and the cylinder 1 coil was replaces and the IAC cleaned. On 7/24/25 the same vehicle behaviors were observed and the same warning lights and messages were activated. I scanned the vehicle and got "p0300 Random/Multiple Cylinder Misfire Detected and P0304 Cylinder 4 Misfire detected. There was a recall on this particular vehicle make, model and year and my vehicle was out of the VIN# range. I firmly believe that the recall needs to be expanded to include a larger number of vehicles...you can google about this vehicle and see many others with similar issues. Usually, the cure is a PCM reflashing/software update that seems to take care of the issue. Please expand the recall before someone dies in an accident because of this problem.

For the 3rd or 4th time since I have own this car I experienced a loss of acceleration when attempting to make quick acceleration while attempting to merge with traffic. Acceleration is fine around town where quick acceleration is not appropriate. But the first attempt to merge with flowing traffic the car will slowly accelerates to about 30 mph and no more regardless as to position of accelerator pedal. On all occasion this bad behavior has this first drive of the day - going to work in the a.m. There is often a warning message indicating the safety radar is not working due to limited visibility which is a very common warning in the a.m.

There is a current lawsuit/settlement stating that there are known issues with the Mazda Connect Infotainment system having technical glitches. I own a 2019 Mazda CX5 and have been having issues with the Mazda Connect pressing random buttons, drastically increasing the volume, the carplay disconnecting while I'm following GPS directions, among other technical issues while I am driving. These are extremely dangerous issues while operating a vehicle and many Mazda owners are experiencing the same issues. With the limited extended warranty, I brought my vehicle into a Mazda service center to get the issue resolved. Although there are issues with the Mazda Connect Infotainment system, they claimed that the issue is not covered under the warranty and I need to purchase a new screen repair kit which would cost $608+tax. I believe they are trying to get out of repairing the issue and the repair kit they are recommending should be covered as well. A recall should be made to cover these issues.

I am the owner of a 2019 Mazda CX-5 (non-turbo) which experienced a cylinder head leak requiring full replacement. The repair was done by Riley Mazda of Stamford on July 28, 2023, at a personal cost of $4,074.34. Mazda has acknowledged this defect in turbocharged CX-5 models from the same year and issued a reimbursement program. However, Mazda has declined reimbursement for non-turbo models, even though the failure is the same, and the repair used identical part numbers and labor hours as listed in Mazda’s own TSB for the turbo reimbursement. This indicates a broader issue affecting both engine variants. Mazda’s refusal to extend reimbursement to non-turbo owners is unfair and leaves affected customers with no support for a known manufacturing flaw. I urge NHTSA to investigate this recurring engine defect in non-turbo 2019–2020 Mazda CX-5 models and encourage Mazda to offer equal reimbursement.

My infotainment system regularly ghost jumps between screens and adjusts the volume of music (both on CarPlay and regular radio) by itself. The car turns off CarPlay regularly, including the navigation, which is dangerous when you are not sure where you are going. The sound is the worst part of it, as it will change the volume to unhealthy levels without warning. Even turning it off does not stop the jumping, as it turns itself back on. While Mazada did provide an extended warranty for this exact problem, they will not cover the display which they allege is the problem in my car and told me it is a $600 replacement fee that I am fully responsible for, even though their screen does not work. This issue is all over the internet with Mazda refusing to fix it but it's an issue that can cause serious safety issues (with navigation failing and especially with unexpected volume changes). There is no rhyme or reason to when it happens and when it doesn't. It will be fine for a few days and then not work at all for a day. This has been ongoing for about a year. My car has about 55,000 miles on it.

While driving on a 75 degree and sunny day my Sunroof exploded. There were no cars around that could have thrown debris up. Luckily I had the shade cover closed or I would have been showered with broken glass.

My vehicle has 64k miles and has had regular maintenance - oil changes, etc. it has recently developed an oil leak. I took it to the dealer today & they said the cylinder head and gasket needs to be replaced. My car has not overheating or even run warm. I understand there are 2019 CX-5S that have had a casting issue with cylinder heads. I feel sure that’s what the issue is here yet they want almost $6k to repair my vehicle!

I’m reaching out regarding a persistent issue with my Mazda 2019 cx5 infotainment system. The screen is experiencing frequent “ghost touch” or phantom button presses, where functions are activated without any input. This makes the screen erratic and often unusable, creating a distraction and raising safety concerns while driving. I’ve already restarted the system and attempted basic troubleshooting, but the issue continues. I’ve learned that this is a known issue in various Mazda models, and I believe this should be covered for repair, especially since it impacts both functionality and driver focus. I’ve already contacted Mazda customer service and my local dealership; however, they advised that the repair would need to be paid out of pocket. Given the nature of the issue and the potential safety concerns it presents, I strongly believe this is something that should be covered by Mazda. Please let me know how I can escalate this issue for formal documentation and create a new recall. Thank you, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2019 Mazda CX-5. The contact stated that while operating the vehicle, the message that the engine oil level was low was displayed. The contact stated that oil was added to the engine; however, the next day the message reoccurred. The contact stated that later while the vehicle was parked, the contact discovered an oil leak underneath the vehicle. The vehicle was driven to the local mechanic who confirmed oil leaking from the engine, but the cause of the oil leak was not yet determined. The local dealer was contacted, and a service appointment was scheduled. The cause of the failure was not yet determined, and the vehicle was not yet repaired. The manufacturer was not contacted about the failure. The failure mileage was 96,600.

One of the cylinder heads on the back portion of the motor cracked, leaking oil down into the engine compartment. I didn't realize this was an issue until I got a warning about low oil. I went and got an oil change and within 2 days I had the low oil warning again. I had no other warnings that this was going on. This creates a potentially dangerous situation with people leaking oil onto roads and highways unknowingly. It was inspected by Mazda and confirmed to be the issue. There is currently a TSB from Mazda about it. But my car wasn't included in it. TSB 01-002/23

Just got diagnosed with cracked cylinder head. After looking on social media, it appears this is a thing for the model years 2018 and 2019. Bad casting? Anyway I believe this should be a voluntary recall to correct such a flawed engine. I bought this new from a Mazda dealership and kept it up to date with service only through the dealer. The 60 month/60,000 mile drive train warranty ran out last July. However I only have 50,000 miles on the car...babied.

At 30,000 miles car began leaking oil severely and was told that the engine block was cracked and needed to be replaced. There are numerous complaints of this same issue online happening just after the warranty has expired. The cost of repair is $6000.

Unknown. Ticking noise on engine.

The engine cylinder head cracked before the vehicle hit 50,000 miles. This caused oil to leak and burn in the engine compartment, leading to a burning smell coming into the cabin. Once enough oil had been lost, I got a low oil pressure light. I immediately pulled over and noticed white smoke was coming out from under my hood, and the smell of burning oil was quite strong. The problem has been confirmed by my mazda dealer. The vehicle has not been inspected by manufacturer, police, insurance. Just the dealer. The vehicle is currently at the dealer, and the cylinder head would need to be removed for inspection if requested. The smell of burning oil was the only early symptom, though I did not recognize it at the time.

The contact owns a 2019 Mazda CX-5. The contact stated that while driving up on incline at 45 MPH, the engine shut off with the check engine warning light flashing on the instrument panel. Despite the failure, the contact was able to pull the vehicle off to the shoulder of the road. Due to the failure, the vehicle was towed to the residence. The following day the vehicle was towed to an independent mechanic; however, the mechanic was unable to duplicate the failure. The mechanic replaced the spark plugs and the ignition coil. The mechanic referred the contact to the dealer for additional assistance. The contact drove the vehicle to the dealer with an abnormal rumbling sound coming from the vehicle. While at the dealer, the dealer was unable to determine the cause of the failure. The contact was provided an estimate for repairs unrelated to the failure. The manufacturer was notified of the failure and provided a case number. The vehicle was not repaired. The failure mileage was a 129,000.

The Mazda Connect screen has ghost touch issues. The screen randomly presses buttons while the vehicle is in motion. The most dangerous component is when it changes the lighting to nighttime during the day causing me to be unable to see my screen during the daytime. It also repeatedly skips music, changes the screen while the gps is on, and constantly presses random buttons and disturbs me while I'm driving the vehicle. This is a known issue amongst many Mazda models that they have yet to fix and it is highly distracting.

Valve cover develops crack causing significant loss of oil resulting in seizing of engine with the potential of serious accident and potential loss of life.

I had my vehicle looked at and found a cracked cylinder head on #3 and did some research of people having the same issues. I was driving when the vehicle started smoking it turns out the oil coming out of cylinder #3 flows down the driver and passenger side behind the exhaust manifold which can lead to a fire. My car only has a little over 80,000 miles and this should not happen around that low of a mile vehicle. I believe this is an issue that needs attention.

While driving, the infotainment screen went crazy! It randomly changed screens rapidly, and the navigation voice started talking loudly about changing volume level, and repeatedly. Very distracting and dangerous.

This is a complete electrical system failure. My screen continues scroll All Systems fails. At least it is not draining the battery again. I have had to replace the battery 2 times in the last 6 months. Maybe CarMax sold me a "lemon". . I received a recall notice, however when I spoke with the service department at the Bob Mazda dealership in Carlsbad and they told me that the recall on my vehicle is closed. I can come in for repairs, but at my own expense. I have only owned this vehicle for 6 months in which 2 months I was in the hospital recovering from a major surgery. When I get in my car and start it, if it starts the "blue" light is on every time, which is apparently Thermostat. After about 20 minutes or so the light turns off, sometimes 30 minutes. The next part is the scrolling malfunctions. It lists about everything on the car. I am [XXX] and live in Baja. I live in a very safe, gated with a security guard neighborhood, however I am scared of going any due to my car issues and being stranded. I also really need to cross the border to see my doctor but I am afraid. When you have to replace 2 batteries in 6 months and I have only driven under 5,000 since I purchased the car. Mazda needs to make me whole. My car also only has 24,000 and when I bought it had20,000 miles. There is something seriously wrong, actually multiple things are wrong with my 2019 Mazda. A person should never be afraid to get in the vehicle due to safety issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2019 Mazda CX-5. The contact stated that while the vehicle was parked, the contact discovered an abnormal odor coming from the engine compartment. No warning light was illuminated. The vehicle was taken to a dealer, where it was diagnosed that there was a cracked cylinder head and that the cylinder head needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 26,000.

Cracked cylinder head. Major oil leak. Oil light came on but then turned off. No other warning light. No engine light came on. The vehicle was taken to the dealer for diagnosis.

The cylinder head in the engine cracked while I was driving. The vehicle was leaking oil profusely and was down a quart after the oil had been changed the week prior. There were no warning lights or indication and I had just had the vehicle in the dealership the week before. I'm a disabled driver that requires hand controls so if I needed to exit the vehicle and move away from it it would not be possible. It's been at the dealership since 2/24/25. I have found numerous other people that have experienced the same issue online.

With only 60k miles on my car which I regularly take in for maintenance, my car started to leak a ton of oil. It was determined that the cylinder head is cracked. This should not happen on a car this new and maintained. In doing research, this seems to be a common occurrence with this year.

On [XXX], I was the operator of a 2019 Mazda CX-5 in Los Angeles, California. I parked the vehicle on an incline on or around [XXX] in Los Angeles, California, and then exited the vehicle. The vehicle remained stationary for some time, until it suddenly began rolling backwards at a speed that pushed me to the ground while I was getting my things from the passenger side door, causing me serious injuries.

The cylinder head on my 2019 Mazda CX-5 failed prematurely due to a known defect. The vehicle is currently at Fred Beans Mazda in Mechanicsburg, PA, where the issue has been diagnosed and confirmed. The defective component is available for inspection upon request. This failure created a serious safety risk due to an oil leak, which led to smoking from the engine bay and a potential fire hazard. If the oil had ignited, this could have caused severe vehicle damage or injury. Additionally, the failure could lead to a sudden loss of power while driving, increasing the risk of an accident. The problem has been reproduced and confirmed by the dealership, and Mazda has been contacted regarding assistance. They have acknowledged the issue but have not provided full coverage for the repair. Prior to the failure, there were no warning lights or messages. The only symptom was an oil leak, which led to smoke coming from the engine. This issue appears to be a common problem with this model, and Mazda should take responsibility for addressing it properly before it causes serious harm.

While driving the vehicle, I started smelling a burning smell about 10 days ago (2/17). I also felt a slightly reduced engine performance and could see the car emitting smoke from the engine bay. I had no warning lights on my dash. For all I know, the engine could've blown while I was driving on the road. Upon taking the vehicle to the dealership 2 days ago (2/25), they informed that my car has a cracked cylinder head, and there was no apparent reason why this would happen. The vehicle has only been inspected by the dealership thus far and I was quoted $5,700 to fix the issue. Upon looking up the problem, I see this is a common issue, with many having experienced it before, but no TSBs issued for this. There is a CSP issued for vehicles of the same year, but limited to the Turbo version on the engine. Unfortunately, I do not have any warranty on the car currently.

This concerns a 2019 Mazda CX5 with approximately 52,000 miles - the engine of this vehicle is the 2.5L naturally aspirated version. Driving the vehicle with the HVAC system on resulted in a burning oil smell coming through to the cabin. Upon owner inspection, engine oil was seen as coating the underside of the vehicle in various areas. The oil pan drain plug and oil filter were both found to be tight and not leaking oil. The vehicle was taken to a nearby Mazda dealership for inspection on 2/26/2025. On 2/27/2025, Mazda technicians state that the cylinder head on the vehicle engine requires replacement. Replacement is quoted to be in excess of $5000. Reviewing the issue online shows numerous similar cases of engine cylinder head failure. This vehicle comes equipped with cylinder deactivation which seems to have a higher rate of failure regarding cylinder heads and a potential design flaw with cylinder heads manufactured in a time frame of 2018-2020. Leaking oil could potentially start a fire as the oil drips onto the exhaust manifold when the car is at operating temperature.

The infotainment system within the Mazda has a variety of issues. 1. Its CarPlay system is extremely slow to connect to the mobile device via a USB. 2. 'Mobile Device Error' message pops-up frequently and disconnects the infotainment system from the mobile device. 3. 'Ghost Touch' occurs when driving under 20 mph. The screen fritz's out, will randomly press buttons, turn settings on and off, and there is no control over it. 4. Screen freezes. System and screen will either lag extremely slowly, or will freeze entirely. In sum, these issues are not only annoying but also a safety concern. It is extremely distracting for this to happen while you are operating the vehicle. Furthermore, it suddenly removes your mapping/navigation directions that you might be using.

The contact's daughter owns a 2019 Mazda CX-5. The contact stated that while her daughter was driving at undisclosed speeds, the Mazda Connect Center Display touch screen was operating independently, causing vehicle functions to be engaged unintendedly. The contact was concerned for her daughter's safety because the center display functions included safety lane departure warning, blind spot monitoring, and traffic sign recognition safety functions. The contact related the failure to Mazda Special Service Program (SSP) Number: B6. The dealer and the manufacturer were notified of the failure. The vehicle was not diagnosed or repaired. The failure mileage was approximately 30,000.

I hope this message finds you well. My name is [XXX] , and I am the owner of a 2019 Mazda CX-5 purchased as part of the Certified Pre-Owned (CPO) program. I am writing to formally address two concerning issues related to my vehicle’s warranty coverage and its safety. 1. Warranty Coverage for Drive Belt Tensioner: During a recent visit to your dealership, I was informed that the drive belt tensioner on my vehicle is not covered under the warranty. This contradicts the coverage listed on your official Mazda CPO Warranty, which specifies that the Limited Powertrain Warranty includes the engine, timing chain, tensioner, and associated components. The drive belt tensioner is clearly referenced in this section, yet I was told it falls under wear and tear and is not covered. I kindly request a detailed explanation regarding this discrepancy. I believe the information I was given does not align with the warranty’s stated coverage, and I am concerned that the dealership is not honoring the terms of the warranty as outlined on your website. 2. Ongoing Noise Issue: Additionally, my vehicle has been making an unusual noise, which I reported during my visits to two separate Mazda dealerships. Unfortunately, despite multiple attempts to diagnose the issue, neither dealership has been able to identify the source of the noise. This situation has left me feeling unsafe while operating the vehicle, as I am unsure of its origin or potential impact on my vehicle’s performance or safety. I would appreciate it if you could escalate this matter and offer assistance in determining the cause of the noise, as well as ensure that all components of the vehicle are functioning properly. The lack of resolution is not only inconvenient but also concerning from a safety perspective. Request for Resolution: I trust that Mazda values its customers and will make every effort to resolve these issues in a timely manner. I respectfully request that the drive belt tensioner be covered und INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Car will slam on brakes even if car is in opposite lane farther away. We have received sooo many chips amd cracks on windshield with 2 weeks. We purchased used and was informed windshield was replaced once already.

Oil started leaking while car was idling causing smoke to enter the cabin as well as all under the hood. Car was undriveable at this point. She was lucky there was no traffic. Car had to be towed and cylinder head was cracked. Mazda has a known faulty cylinder head problem they have refused to fix and this caused a safety issue. Vehicle will not be able to be inspected as we had it towed to get fixed immediately. The service center did confirm this is the issue and there were no prior issues before this.

I own a 2019 Mazda cx 5 and it has 78,000 miles. I noticed smoke coming from the engine and a lot of oil leaking on the ground. I brought the car into my independent service center and they confirmed that there was a crack in the engine cylinder head. There is a TSA # SA-031-21 on this problem. I feel that my safety was at risk, since the engine could have seized while driving. This vehicle is available for inspection upon request. No warning lamps or messages were displayed, however there was a strong odor of burning oil. This problem occurred on 1/9/25 and it has been in the service center since.

As I was driving, a burning smell emanated from the car. There were no check engine lights on. When I pulled over, I saw a lot of smoke coming from the engine. I checked the oil level and it was above the minimum line bit just barely, even though my husband had just done an oil change on it. I refilled the oil and continued on my trip. The problem repeated for several dqays until I got home and took it to the Mazda dealership. They reported the following: "Cylinder Head Assembly: oil leaking out of back of head, recommend replacing cylinder head and related gaskets. The cylinder head sits above the cylinders on top of the cylinder block. It closes in the top of the cylinder, forming the combustion chamber. This joint is sealed by a head gasket. In most engines, the head also provides space for the passages that feed air and fuel to the cylinder, and that allow the exhaust to escape." This service is $5600! My car only has 80K miles on it. This is a safety issue because there was no warning. No check engine light appeared and there was no warning.

Good afternoon. I am reporting an incident that occurred on December 29, 2024. I was driving my 2019 Mazda Cx-5 and I was about to make a left turn. However, as I was making the left turn, I received a notification on my dashboard about a "Forward Smart City Brake Support Malfunction" (a photo of the notification will be included). My car instantly lost control and it did not stop until it collided with the street curb of the road I was attempting to turn on. Fortunately for those around me, my car did not collide with any other vehicles on the road. However, this collision caused damage to the right side of the vehicle, as the right airbag of the vehicle had deployed. I believe that this is a very significant problem that should be looked into as soon as possible. If my car were to hit other drivers on the road, it could have led to a very tragic incident. As far as repairs go, I wanted to wait and see how this complaint would carry out. I do not believe that it would be fair for me to pay repairs for an event that was out of my control. Thank you.

Car was purchased in June 2019. Car started smelling like burning oil and started finding oil pooling under the car around November 2024. At time the incident was discovered, car only had 38k miles. There was no warning lights or indication there was an issue other than the smell and small pool of oil under car. The Mazda service manager immediately knew what the issue was and told me they were going to confirm with a full inspection and diagnosis. I was told that I have a cracked cylinder head and I will need to have it replaced. Warranty ended few months prior so they will not cover. I was told it would cost $4589.76. The Mazda service department told me that this is a common issue and to hold off on repair and contact Mazda corporate since warranty just ended. They topped off my oil and told me to keep an eye on the oil level and to wait to hear back from Mazda corporate.I submitted a case with Mazda and the customer care specialist told me that they cannot guarantee they will cover this. Within a week, the temperatures got colder and issue got worse. Low oil light came on, topped off with oil. Lost 4 quarts in one day. Called Mazda service and they told me to top off oil and come drop car off immediately. Upon researching this issue, the cracking of cylinder heads in Mazda CX-5 vehicles, particularly those with the 2.5-liter (NA) engine were widespread and discussed in online forum. The contributing factors of the issue point to a design flaw of the cylinder head due to the cylinder deactivation technology and a manufacturing defect due to the cylinder head casting process based on reports and discussions within the automotive community. A TSB (SA-013/22) has been released for the affected cylinder head with a modified replacement. This seems to be a significant and widespread issue that can cause entire engine to fail and require full replacement. Oil leaking on to the hot exhaust near other engine parts could ignite and put myself or others at risk.

Engine block cracked, passenger cabin filled with noxious odder. Vehicle was suddenly leaking oil at high rate.

My 2019 Mazda CX-5 suddenly developed a major oil leak within the last 7 days. My car has only 44,350 miles and I have had all scheduled and required maintenance completed timely, including oil/filter changes, coolant level checking and maintenance, etc. I took the car to an independent mechanic who diagnosed the problem as a cracked cylinder head. I then took the car to a local Mazda dealer who confirmed the diagnosis and informed me that there would be no warranty coverage as my 60,000 mile/60 month powertrain warranty had expired 60 days earlier. Some two years earlier my car's check engine light came on and overheated. I took it to the same local dealer, who replaced the coolant control valve & related components. In November 2024 I received a "Warranty Extension Program" letter from Mazda about the same fail-safe thermostat problem. I believe this is relevant and related to the cracked cylinder head since almost all instances of a cracked cylinder head are due to engine overheating. This issue put me at risk as I was close to driving the car with no oil and oil leaking heavily onto very hot engine components that could have resulted in a fire. I am now facing repairs to this car between $4,800 and $6,000 and given the faulty/defective cylinder head from Mazda, I could face this safety issue again, as it will be replaced with a similar cylinder head from Mazda!

I started to smell a burning smell while I was driving and noticed smoke coming from under the hood along with the burning smell. When I parked the car I noticed a bunch of oil leaking from under the car. I took the car to get checked out and there was oil all under the bottom of the car and it was confirmed that there was a very bad oil leak which occurred due to a crack in the cylinder head. No check engine lights or any indication of this issue aside from discovering the burning smell, smoke from under the hood, and a significant amount of oil underneath the car. The car hasn’t been driven in a month because of this issue. When you turn the car on you can hear a ticking sound coming from under the hood. The bad part is there was no indication. A 2019 with 50,000 ish miles shouldn’t have this problem and I confirmed that with mechanics and Mazda. This is a safety risk as you can’t safely drive the car without being concerned about the lack of oil in the car due to the leak as well as the smoke coming from under the hood, not being able to drive the car thus resulting in needing the car towed in order for the car to be serviced for this problem. I was told that if the oil continues to leak and if I was to drive it the engine could start to have issues and possibly turn off due to the leakage. This leak had oil all over the exhaust system as well.

We were locked out of the car on a road trip due to a dead battery. We needed to open the car door to pop the hood in this emergency situation. With the Battery down, we had to use the physical keys provided by Mazda to unlock the door. Both Mazda's original keys did not open the driver-side door. We were stranded and had to call emergency key services to open the door. The purpose of physical keys is to open the car in case of emergency but in Mazda CX5 case they were useless. We have also reported the issue to Mazda and are awaiting a response.

This car has less than 37,000 miles on it it has significant oil leaks from the valve cover gasket, it’s timing cover gasket and now it had been determined it has a cracked cylinder head. This was covered by 3 Service alerts with the cracked cylinder head being SA-031/21. None of the dealers notified us of the issue when serviced Galpin Mazda and New Century Mazda. But Big O Tires did. The two oil leak gasket repairs cost over $1600. The car is 8 months past warranty. The car is burning oil when driven. Due to the leak and the smoke particles and smell enter the cabin. The engine smokes when shut down instill it cold down. The smoke particles in the cabin are dangerous. The engine oil light appeared in late November (my daughter’s car, she is away at college). We found out the depth of the oil leak issues the second and fourth week of December. The fact that the dealers did not notice us or do preemptive repairs is a major failure by the Mazda organization.

I have a 2019 Mazda cx 5 with only 67,000 miles on it and the cylinder head is cracked and leaking oil everywhere. I have noticed TSBs released for this issue, but it seems to be a very common issue with most people not being covered for a very major repair. Mazda refuses to fix the issue created by the improper build of this component and may lock people's engines if not caught soon enough

The 2019 has a creaked cylinder with 40000 miles on it. This is a problem with that has been happening. We are 4 months out of the warranty with May 2024.

Brought 2019 Cx-5 to local dealer with complaint of strong smell and smoke coming from hood. Cracked cylinder head at only 21k miles. Known flaw for this particular make and model. Only 6 months out of warranty. Mazda refuses to make it right and only extended warranty for turbo engines. Mazda needs to make this right for ALL engines with this issue.

My Mazda CX-5 was found to have a cracked cylinder in the engine and was profusely leaking oil. When I spoke to the dealership they denied seeing this regularly, however, upon doing research on reddit, it is found to be more pronounced than indicated. There was no known cause indicated, however, on reddit it appears that the original casting done in Mexico maybe the culprit because it is so thin and causes it to crack between 40-50k miles. There is no other sign or warnings, besides an obscene amount of oil leaking. The failure of this could cause the engine to fail while driving. This is a significant risk.

Vehicle has 40k after a oil change noticed oil spots on pavement took it back to the garage that did the task, was told that the leak was near cylinder #2. Called Mazda customer service and was informed that my warranty expired in May of 2024. my mechanic called Mazda parts to get the price of cylinder head and was told that they had a run on cylinder heads due to defective heads coming from the Factory, SHOULD BE A RECALL ON THE MAZDA.

The steering and braking systems on my vehicle malfunctioned after jumping my vehicle when the battery drained too far to start, or even power my cars baseline electrical systems. After jumping my car, I started backing out of my parking spot and when I turned the wheel it very violently jerked in a manner that could have hurt me if I'd been holding onto the wheel tighter. Around this same time I believe I recall the brakes automatically applying and halting the vehicle. I was too far out of my parking spot when this began occurring and had to try to maneuver into a different one, during this attempt both of the conditions described above reoccured several times. I eventually noticed that it only seemed to trigger when the wheel was at more extreme steering angles, by keeping the steering angle lower I was eventually able to maneuver into another spot without triggering the issues. After parking and letting the car run for a bit to recharge the battery I no longer experienced these issues. There were several warning lights related to roll stability control, lane departure monitoring before pulling out. The following warnings were present, but I'm unable to recall whether they displayed before I first hit the issues: Smart Braking Malfunction, Power Steering Malfunction, Transmission Malfunction, Check Engine Light. The vehicle has not yet been inspected by anyone, however I was able to find evidence of other people complaining about what sounds to be the same issue going back several years online.

The head gasket cover is leaking leading to a great deal of smoke. The car should not be driven per my mechanic due to risk of fire

Mazdas infotainment system was issued defective. The system is plagued with issues in which a “ghost” touch on the screen makes changes to the system. It is a very distracting issue and poses a safety concern as it distracts the driver from the road as the ghost touch can make changes on the infotainment system moving between settings, changing music, making random calls, and randomly triggering voice assistant if an Apple car play is connected. This is a known issue for which Mazda has a fix but has never issued a recall. If you search online you will find hundreds of examples of the ghost touch affecting Mazda vehicles.

I have 115k miles on my 2019 CX5. Never has any issues. Now all of a sudden I have a cracked cylinder head leaking oil. I was smelling smoke but mot seeing it. I took into dealership they noticed oil dripping thus why smell. Its a $4500-5000 job. I cannot afford this. This should not happen at this kind of mileage. My warranty just expired too. Mazda needs to cover these type of repairs

The vehicle starting stalling, check engine light would come on, and the vehicle would slipped into “limp mode” while traveling on the freeway. I was amount in two auto collisions because of the vehicle slowing down in the middle of the highway. The problem started in August 2023 and was towed to the dealer on one occasions and towed to my home on another occasion. The dealer ran a diagnostic and said it was the brand new battery I had installed and then the catalytic converter. After repairing both; the vehicle proceeded to not drive over 30 miles per hour. The dealer said it was the engine and then said it was something else. I’ve expressed that the symptoms are those more aligned to the PCM issue recalled on 2019. A actual diagnostic report from Auto Zone supports this. The vehicle has also been inspected by another Mazda dealer and a stand alone mechanic.

Car failed while on highway driving 60 mph with the engine and power steering turning off instantly. A day prior the dash was blinking warnings. Mazda of Lodi replaced the entire transmission plus other parts. Just made it under warrantee. Would have cost 5k once expired.was told half the fleet of 2019 were recalled but not the second half of production for some reason even though they both experience the same failure.. also had 22,000 miles at end of the. Something smells in Denmark

At 49k miles and 4 months out of warranty, the car began leaking oil and smelling like smoke. The dealer diagnosed with a cracked cylinder head and repaired it.

Infotainment screen malfunctions, pressing buttons by itself.

CX5 Cylinder head cracked at 53,500 miles. Was driving when received engine overheating and pull over immediately warning. The car smelled like maple syrup as it was engine coolant burning. Took it to the dealership and they informed me of the cylinder failure. It is currently awaiting parts and its not under warranty.

Cracked cylinder head requiring replacement at 62,000 miles.

While driving, I received a warning that the engine in my car was overheating. Upon arriving home and parking, I noticed pooling under the car. My car was due for an oil change so the next day I dropped off the car for the oil change and mentioned the overheating message and leak to the technician thinking the fix would be routine. To my surprise, I was told my vehicle had a serious coolant leak related to a cracked cylinder. I was advised to take the vehicle to a Mazda dealer. Morrie's Mazda in Minnetonka, MN confirmed the cracked cylinder head which required a full engine replacement despite the car being only ~5 years old and having ~63,000 miles. Mazda had issued a technical service bulletin on this issue but had not issued a recall. As a result, I was left with a large repair bill to replace the engine in a relatively new car. This is a serious issue and I feel Mazda put my life and others in jeopardy by not recalling vehicles and letting customers drive with the risk of the engine overheating.

The infotainment system ghost touches on its own. It changes all car settings by itself. Active driving display, safety features like distance recognition, lane assist, blind spot monitoring, etc. Every setting available in the infotainment system gets changed or reset on it own. Even when you turn it off. It turns back on. GPS routes, dials people, hangs up, mutes on its own, etc. Mazda dealership says it’s out of warranty and I would have to pay out of pocket to fix it. However it is an ongoing issue where now there is a class action lawsuit.

Coolant leaks at cylinder head on 2019 Mazda CX-5 Grand Touring Reserve. Mazda North American Operations released a technical service bulletin (01-013/21) regarding 2016-2020 Mazda CX-5, CX-9, and Mazda6 with SKYACTIV-G 2.5T engines. This issue can cause the engine to leak coolant, overheat, and stall, potentially leaving the driver and passengers stranded in an unsafe location. Mazda is aware of this manufacturing defect but has not recalled these engines to be repaired or replaced if they are outside of their manufacturers warranty period and placing costly repairs and potentially life-threatening situations as the responsibility to their customers. The diagnosis to repair this issue is a replacement of the cylinder head/sleeve or replacement of the engine block, which has since been modified by Mazda to resolve this issue. This is a costly repair for diagnostics, labor hours, and parts and Mazda is refusing to be held responsible for these defects outside of the power train warranty period. Mazda customer support advised this will only be potentially covered if diagnostics are completed at a Mazda dealership and does not provide any assistance if the customer uses a non-Mazda affiliated repair shop. Messaging on the dash console advised excessive heat and thermostat was nearing 260°F

Started smelling smoke randomly and discovered an apparent oil leak in the engine. Mechanic inspected and noted that it appears to be an issue relating to the cylinder head/head gasket, which is in line with a technical services bulletin put out by Mazda several years ago for this make/model/year for a known design flaw that can result in catastrophic engine failure. I am just outside the five year warranty but well under the 60,000 miles, so expecting them to tell me they won't cover the repair even though this should have been a recall due to the potential outcome. I cannot drive the vehicle until this is repaired because it can cause engine fires (or worse).

There is a coolant leak at the cylinder head. We have been told that the cylinder is cracked at the back of the cylinder head where the exhaust ports meet. The dealer's technician said there is a "redesign" in the cylinder head. This is a known issue that is a defect apparently due to Mazda's design of securing the turbo on exhaust studs that are not designed to hold the weight. Why has there not been a recall? There is a Mazda TSB - 01-013/21, issued 10/15/2021 Verbal estimate from dealer for repair - over $7,000

My vehicle started smoking and I smelled a oil burning smell coming through the vents. I took it to the Mazda dealership and they diagnosed it with a cracked cylinder head. The repair estimate is $4,900. It is a 2019 with less than 60,000 miles, but it is a few months out of the powertrain warranty. However, this is a KNOWN issue to Mazda. As I have been researching online, many Mazda CX-5 owners have reported the same issue and I believe Mazda has traced it back to defective manufacturing in a batch of these parts. My local mechanic has also told us that he has seen this issue with 2019 Mazda CX-5s and recommended we report them. Mazda SHOULD issue a recall, but I understand that is expensive for them. At the very least, they should alerting drivers to this possibility and voluntarily repairing these cylinders without cost to unsuspecting drivers who could end up with an engine fire. I have submitted a complaint to Mazda customer service and I am awaiting a response.

I am writing to express serious concerns regarding the recent service that occurred on November 14th, 2023. Due to the service's failure and negligence, Luther Brookdale Mazda has jeopardized the safety and well-being of my family members. On [XXX], my 2019 CX-5 was towed from Monticello, Minnesota, to the dealership in Brooklyn Center around 9 pm. While returning from [XXX] dinner in St. Cloud on [XXX] , a sudden warning appeared on the dashboard: "Engine Coolant Temperature High. Stop the vehicle immediately in a safe place." Upon receiving this notification, we pulled over to the shoulder and observed smoke emanating from the engine bay. We promptly turned off the vehicle. Concerned for our safety, we contacted our family to pick us up and had the vehicle towed by AAA. As we awaited the tow truck's arrival, we noticed coolant had sprayed all over the engine under the hood, and the engine cover was missing. Furthermore, the coolant reservoir was below the minimum threshold. This particular issue is the reason I brought the vehicle in for service the week prior, regarding insufficient coolant temperature. It was evident from the state of the engine bay that the dealership failed to follow proper protocol. This lack of oversight likely resulted in damage to the engine and other essential vehicle components, leading to the total loss of the car. I am deeply disappointed by the lack of care and attention to detail in the service provided. This negligence also compromised my family's safety. Moreover, what was meant to be a festive holiday was marred due to the disregard for my property. I have been a loyal customer at Luther Mazda Brooklyn Park for several years, and I am shocked by the incident that has transpired. We have approached the dealer with the issue and they are continue to articulate that there is no engine damage, but with the ongoing class action lawsuit, I am extremely skeptical of their claims.

The display screen appears to initiate "ghost actions". It will change songs, put phone calls on mute/hang up, change display settings etc. on its own. I looked this issue up online and it seems to be very common with 2017 and newer Mazdas. I took it to the Mazda dealership and they wanted to charge me $150 for a diagnosis and another $500 for a screen repair. I decided not to do it because all of the threads online stated that this didn't fix the issue so no diagnosis was made. It doesn't put me at extreme risk but it is very distracting when I am using maps or CarPlay.

The INFO touchscreen randomly activates itself (the commonly reported "ghost screen" problem that occurs due to defective coating on touchscreen) which cause settings and selections to change uncontrollably, including placing phone calls, etc. This is very distracting and hazardous for this to randomly happen while operating the vehicle.

The main display has failed and/or malfunctioned regularly. Lighting systems for vehicle navigation system has been impacted and HUD lighting and visibility have been impacted. My safety and the safety of my passengers have been put at risk because of distraction and vehicle navigation malfunctions. The component has not yet been inspected. There were no other problems prior to failure. The first incident of this occurred several months to a year ago. This has been a continuous issue. The date provided below is simply to indicate that this has been occurring for an extended period of time.

This report is for a 2019 Mazda CX-5 with the Naturally Aspirated/Non-Turbo engine. This vehicle only has 26,500 miles and has developed a major oil leak from a cracked Cylinder Head. The continued safety of the vehicle has been degraded. The engine could seize while driving making the vehicle inoperable while on roadways. The vehicle has been inspected and confirmed by both an independent service center and by an authorized dealer service center. The only warning lamp that appeared was a low oil light. I immediately pulled over for safety and inspected the oil levels of the engine. I determined the engine oil levels were just below the fill line on the dip stick. I then added approximately half a quart of recommended oil and the oil warning light turned off. I then contacted a local service center for diagnostics of the problem. They determined the cause of the oil leak which was a Cracked Cylinder Head on the Engine. I then drove the vehicle to an authorized Mazda service center at the dealership. They also diagnosed the problem as a Cracked Cylinder Head on the Engine. Both the independent service center and the authorized Mazda service center recommended a full Engine replacement.

I have a 2019 CX5 Mazda that consistently leaks oil and smokes. After taking it to a mechanic, I learned that this is a known Mazda issue, but because my car is under warranty, they won't help me. The Cylinder head is pours, and my mechanic said even if he replaces it, it will happen again due to the design. After I have checked online, it seems that MANY people have this issue from 2018-2021. Mazda even made TSB #SA-031-21 to cover some of this issue but no recall. As mentioned, my car leaks oil everyday, and I have to constantly put oil in just to keep it from burning up. It smokes really bad, but I cannot afford a new car or afford to pay over $3K to get this fixed, or don't understand why they won't fix it if they know it was poor design???

UNKNOWN. Vehicle stalls and jumps when I step on the gas pedal or try to increase speed.

Mazda infotainment system experiences ghost touching. It would operate on its own and exit applications like navigation on its own. Mazda is aware of the issue but won’t issue a recall. This can be a safety hazard when the system exits out of navigation in the middle of nowhere. The system would also make calls on its own which would cause a panic to the driver who is distracted trying to end a call they never placed.

The contact owns a 2019 Mazda CX-5. The contact stated while driving 35 MPH, the vehicle was smoking. There were no warning lights illuminated. The vehicle was taken to the local dealer but was not diagnosed or repaired. The vehicle was taken to an independent mechanic, who determined that there was oil leaking from the main gasket and referred the contact to the dealer. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 31,000.

The 2019 Mazda CX5 GT started to make a clicking noise coming from the engine. After much investigation online, sharing multiple resources of videos and sound this seems to be the hydraulic lash adjusters for this specific year and model. Unfortunately this is outside the normal warranty and wasn't noticed until now. The car was inspected by local independent service center. This would pose risk to my family and others if the vehicle seized to work properly. There were no warnings given other than the clicking noise and inspected.

The video display board does not work properly. It randomly changes settings while driving and is very distracting and does not allow the GPS to work properly. It changes radio and display settings and any setting prev set. It cycles through them and randomly changes them The dealer (Kings Mazda in Cincinnati Ohio) stated that this is happening frequently in Mazdas and will cost over $400 for an after market fix and over $1000 for a Mazda fix. It is VERY distracting while driving

engine head crack causing antifreeze leak. caught problem at 65980 miles. Defect confirmed by dealer. I had no indication of problem, only a terrible smell/odor. Dealer indicated a $6000+ cost of repair.(out of warranty). Thank goodness for extended warranty I purchased. I feel Mazda should be held accountable.

Back up camera display does not always immediately come on when placing car in reverse. It can sometimes be 10 -15 seconds before an image appears. I wait in the garage, driveway, or parking spot before backing but this potentially puts pedestrians behind the vehicle at risk. Per FMVSS 111 guidelines. S5.5.3 regarding response time: The rearview image "shall be displayed within 2.0 seconds of the start of a backing event." Problem has been intermittent but frequency seems to be increasing. I took the car to Headquarter Mazda in Clermont Florida. I was advised a software fix is available for the cameras but the cost would be $220 even though I have Mazda Extended Confidence warranty in effect.

"Ghost Touches", a known service alert for several years now, have stated to affect my car in the past couple of years. At times, it will max out my volume to blast through the car speakers, change settings in my car system (gps, phone, etc), and more. Mazda hasn't issues a recall on this, despite safety concerns by many owners.

Went to drive home from work one night, car had been normal until this event. Car suddenly began to state that it was overheating and throttled my speed down to 20 MPH. I was in the middle of traffic going 40-50 at this time. Turns out there is a VSB regarding a coolant leak that can occur and break. Nothing about how you are suddenly governed to 20 MPH

I had just had my car serviced for 30k services and about 2 months later smoke was coming out of my engine after driving. Took it in and it turned out to be a cracked cylinder head. None of my lights were on indicating there was an issue either. I was told this is a known issue with Mazda and should be a recall but there still isn’t one. TSB#SA-031-21

Just as the recall issued for the 2014-2016 the Mazda Connect Touch Screen continues to be an issue for most owners with this Infosystem. Mine for two years since I bought it will do the “ghost touch” on its own, literally operating on its own. My settings change on their own, doing such things as the volume on its own going from a normal tone to blasting, causing such alarm that I’ve nearly gone off the road. My back up screen brightness changes on its own, causing a real safety concern of running into something or someone. This is just two examples…all of the functions go “haywire” and just change at any unexpected time. This issue can be seen over and over online by Mazda owners. And I’ve reached out to Mazda themselves who state they are not aware of any issue, yet the dealerships are well aware of this dangerous issue and quickly know exactly what the issue is when you explain what the car is doing and let you know that for $1200 they can replace the info system. I just don’t see how they can have this issue since at least 2014 and continue to sell cars with the same issue a recall was issued for. It’s so dangerous.

Crack head leaking oil

My Mazda connect touch screen operates by itself (ghost touch) while driving down the road. My safety is at risk trying to press button to get it turned off, while driving down the road. It is a huge distraction. The volume speakers at the high level and continues to beep and yell your audio will be at this volume level (the loudest). It is not listed as a recall foe this make and model, but should be. Doing further research this looks to be an issue with all of their vehicles and Mazda is not holding themselves accountable or trying to fix the issue in newer vehicles. There have not been any warning signs. I’ve had my car for 5 years come this August and my vehicles has been doing this for about 6 months now.

Cylinder failure low oil pressure and check engine light. Mazda redid cyclinder and still getting the check engine light. Mazda working on issue and having issue resolving problem.

The Cylinder head cracked and caused oil to spill out. This was inspected at Towne Mazda in Orchard Park, NY. I was driving ~50 miles when the issue occurred, and had driven approximately 40 of the 50 miles when me and my sister pulled over and noticed my engine smoking and the burning smell to be pungent. Had I not pulled over, It could have led to engine misfire and damage to other parts of my vehicle. The Dealer confirmed the need for a new cylinder head and parts, and is currently repairing the vehicle. The Component was not recently inspected by the manufacturer, police, insurance. During the course of driving, after about ~35 miles, the oil pressure light turned on. I drove roughly 5 more miles before I pulled the car over to have it towed to my Mazda dealership.

The infotainment screen is malfunctioning and acts on it own. Random parts of the screen are touched on its own creating a lot of distractions. Examples are changing of screens, settings, ending my navigation, calling contacts etcetera. This is a huge safety hazard and Mazda dealerships are charging for diagnosis for a commonly known issue, claiming the cause is unknown, despite numerous posts and threads online linking this to a screen delaminiation issue.

As I was driving home one day in February 2024, my car felt like a strong gust of wind was getting up underneath the hood of my car, causing it to pull left and right slightly. When checking the weather, wind gusts were at 5 MPH and you could barely see trees/leaf movement. I pulled off the side of the road, checked underneath the car to see if anything was dragging/missing and all was fine. As I started driving again, I then noticed my RPM's vs MPH was very strange. When accelerating, the car randomly increased up to 4,500 RPM when trying to go 45 MPH, then shifted down to 2,000 RPM's once I reached 45 MPH. But, no matter if I left my foot on the gas pedal, lifted my foot off of the gas pedal or hit the breaks, the car would not move off of 2,000 RPM's until I pressed my foot on the break all the way down to the floorboard. No lights came on at all. I took it to the dealership that I purchased it from, expressing the scary feeling of the driving the car and showing video proof of what the car was doing in RPM's vs MPH. After further conclusion, they determined that a "sensor" had gone bad. The thought that a plastic, electronic sensor going back caused my car to feel that way and put my life at risk while driving is a scary thought. Fast-forward to April of 2024, similar symptoms have come back again. Wind feeling like it's getting under my hood, causing the car to pull left and right, RPM's not matching up and now a hot engine with no warning light coming on, is questioning if it's this particular sensor again. Not to mention, I had it inspected by the dealership two weeks ago and had an oil change done to it and the dealership said "everything looks great". You should have zero thought or worry when operating your personal vehicle, but in the past three months, I have taken my car to the dealership and or a mechanic 7 times with thoughts/worries about my car. This car has now turned into a "lemon" as one would call it and I'm terrified to even start the car.

Engine is ticking and shaking at idle more than normal Rest unknown

Had a constant Valve tick on cold starts and sometimes while running long periods. Oil level top offs and changes did not remedy the issue. Mechanic says it's a bad valve lash adjuster.

The electrical system malfunctions repeatedly. The volume on the navigation will set to maximum by itself. This is alarming and poses a safety risk. It also randomly texts people detailed location information of the driver. This is a safety risk for minors and people in abusive relationships or with a PFA order. It appears to be a common problem with this car.

I developed a cracked cylinder head in my 2019 Mazda CX-5 that only had 33,000 miles on it. I lost approximately 50% of my oil in a 4 mile drive. I believed I had been leaking oil, checked the dipstick, drove 4 miles (max speed of 35 mph), smelled the burning oil, pulled over, saw smoke coming from the hood and checked the dipstick again. Losing this much oil is a safety risk with the possibility of a fire especially if driving at a faster speed and inability to have a safe place to pull over along with smoke from the burning oil causing visibility issues which at higher speeds such as on an interstate can cause a safety concern. No indicator lights/messages appeared, this was determined from seeing what I thought was oil on the ground and then checking the dipstick. Mazda is well aware of the issue. When picking up the car for the dealership after being fixed, I asked what kind of parts were used to ensure this does it happen again. The shop employee said they were “revamped” parts due to the known issue with this model and pointed out 4 other Mazda cx5s currently in the shop with the same issue getting repaired.

The side mirrors fold in and out automatically. Sometimes they will not open to driving position, leaving the driver without the ability to check them for lane changes. This is a common problem with the automatic mirrors on Mazda vehicles. I have had them repaired once under warranty, but the issue persists. The second issue is the automatic emergency braking. It has activated a few times without need or warning. I have come close to being rear-ended because of this and received negative feedback from other drivers that were following me (use your imagination).

Automatic braking system has almost caused multiple rear end accidents as it still detects cars that have left the lane after they turn. The infotainment system has dangerous ghost touches that glitch every time the car stops which has been reported for Mazdas for the past 7 years with no recall.

Infotainment Issue (Ghost Touch Issue). Mazda has been experiencing problems with the Infotainment Issue (all around the globe.. I am located in Mexico. Not sure if this channel is the right way to ask for help outside the USA); in different models such as Mazda 3, CX5, etc. My Mazda CX5 is a 2019 year model with only 10,000 miles. The "Ghost Touch Issue" started just after the 3 year warranty expired. I have the extended warranty but Mazda just confirmed this issue is not covered anymore and I need to pay approximately $1,000 US Dlls to fix the issue (and only 3 months warranty... recommendation not to park the car under the sun which for me is ridiculous). This "Ghost Touch Issue is more than an annoyance. IT IS DANGEROUS. The vehicle itself says not to play with the system while driving. When the volume goes to max suddenly on the radio and channels or worse, settings suddenly change beeping with each change (this issue causes music stations to skip around back and forth, unattended phone calls, etc); and IT IS IMPOSSIBLE NOT TO BE DISTRACTED. I got involved in a "small" car accident in 2013 due to a distraction while driving due to this crazy "ghost infotainment issue" on my vehicle. Mazda is aware of this issue and issued a service bulletin for 2014-2016 Mazda 3´s to have the screen fixed for no cost. What Mazda is waiting for to fix-make a recall and fix the issue at once? As outlined before this is a Manufacturer issue and they need to get accountable of this. Thanks in advance for your follow up and attention.

Folding side mirror will not open all the way, causing a safety concern when driving.

Had the sudden onset of strong exhaust fumes in the cabin as others have described - especially when idling at a light. Returned to dealer after having it up on a rack to find oil dripping everywhere (shield underneath prevents from seeing drops when parked) - got word today it is indeed the cylinder head assembly. How is oil running on hot exhaust not a fire concern? I had to roll my windows down for fresh air in zero degree weather the fumes were so strong inside the vehicle. On top of that the P0126 (thermostat stuck open) diagnostic code is back for the second year in a row after having the “fix” installed under warranty last year.

My engine started smoking while I was driving fast got out of car oil leaking everywhere there was a crack in the cylinder head, another few minutes of driving and the car could have burst into flames seems like it’s a common issue with Mazda cx5 a quick google search has shown me I’m not the only one with this issue, worst thing about it is Mazda refused to fix it.

At any speed over 55 miles there is a loud whining/whistling/moan at the top of the A-pillars. I have tried taping the seams as well as silicone caulk but nothing works. My daughter has the identical car and identical problem and there multiple videos on-line of the same problem. Definitely a distraction from driving safely.

Mazda ships a defective touchscreen that will degrade and eventually register phantom inputs to the infotainment system. In my vehicle, the screen was able to randomly access my settings, including for safety (blind spot monitoring) and display (driving units, heads up display, etc) and start messing with my settings. When I was using maps, the screen would randomly zoom into different spots, or change my destination, or modify settings. This was an enormous distraction and rendered the screen useless. Also, I was never sure if I stopped the car from changing settings related to vehicle safety because I can't keep my eyes on the screen while I'm driving. It was just registering random inputs all over the screen while the vehicle was in motion.

Car will whine and jerk when accelerating. Car suddenly stopped engaging in gear after it was warm. Dealer states it has internal transmission malfunction at 64k miles. Prior to the car breaking down the vehicle was taken to the dealer for a diagnostic on 12/27/23 and concerns with the whining and jerking when driving were expressed. Dealer reports that the transmission was “operating as designed”.

OIL COMING THROUGH CYLINDER HEAD ABOVE EXHAUST MANIFOLD DUE TO BEING POROUS, CAR LEAKING OIL AND NEED TO PUT MORE OIL IN EVERY OTHER DAY. MAZDA KNOWN ISSUE TSB# SA-031/21

There is a known “ghost touch” issue with this vehicle. I did not realize that until recently but the infotainment screen will randomly activate when at low speeds and/or stopped. This has caused distractions while driving as sometimes it will actually initiate phone calls on its own. Mazda has a technical service bulletin on this but has issued no recall

Power folding mirrors do not fully close or extend during wet weather. This leaves the side mirrors visibility obstructed and could cause accident. This is a known issue and a recall should be immediately issued to remedy this dangerous defective part. Mazda technical service bulletin 09-011/20

The radio/navigation/entertainment system malfunctions. The issue is known as ghosting and is a well-known issue with selected year Mazda's. Radio stations and apps will randomly skip around or the volume of the system will blare out at the highest volume startling the driver. Which has occurred multiple times in my case. The first time I reported it to the dealer, they told me there was no issue. The second time I was informed I could pay for a repair kit and installation for over $500.

There is a known issue with the infotainment systems of several makes/models within a certain date range of Mazda vehicles called Ghost Touch. It seems to mainly occur in very hot or cold weather. The touch screen will press different buttons on the screen on its own, which can be quite dangerous while driving: maps will start directing you to a different location, if you are on a call, it may put the person on hold or call another party. Music skips and pauses. It can cause extremely distracted driving (ie: trying to hang up on someone it has dialed on its own or switch directions back to the original address). Dealerships know about the issue but require a test to be done at the cost of the owner to prove the issue, and then they may or may not cover the cost of the fix. This should be a recall to fix this, but have not. Here is the service alert: [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The 2019 CX-5 has approximately 31086 miles. It was discovered that the cylinder head is cracked and causing the car to leak oil.

My engine suddenly started smelling like burning oil. I was due for an oil change and needed it immediately so I went to a quick oil change shop. They told me oil was sprayed all over the engine and I should take it to the dealer. It's been at Napleton Auto Park in Urbana, Illinois for a week and they finally diagnosed a cracked cylinder head. They said it could take up to 2 months to repair and they're checking to see if it's covered by my warranty.

My 2019 Mazda CX-5 cylinder head cracked at only 60,000 miles. I noticed my breaks were smoking and stopped driving. I then noticed oil leaking from my engine which had blown into my breaks, causing the smoke. There was no check engine indicator on my dashboard, nor did it indicate that my engine had overheated. There was no indication that there was any issues with the vehicle until i noticed the smoke coming from my brakes. I towed the vehicle to the Captial Mazda Dealership in San Jose, CA. Per Mazda Dealership Repair Estimate: "cylinder head cracked by cylinders 2 and 3". When i asked the dealership service center why this happened, their only response was it was a engine failure and that "over time the cylinder can become warped and crack" and while it that doesn't happen often "it can happen" I asked if there was anything I did that caused this, their only response was "i can check with the technician again". Apparently I did not purchase the "extended warranty" so while the repairs are no fault of my own, I have to pay the $6,000 repair cost.

My air bag light warning light is constantly blinking and I took it to the dealer ship. I informed the service guy this could be a malfunction due to a recall. He only asked me to pay for an diagnostic for $175.00. I think based on a history dated from 2004-2018 regarding Air bags recalls this is a recall. I contacted Mazda 1-800-222-5500 Option 11/28/2023 @ 10:00 am I reported this to Mazda Vehicle Claim#[XXX] and they are stating it is no recall for that vehicle. I think this is a safety risk for me and Mazda needs to address this at no charge based on the history of several vehicles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Cracked cylinder head which caused engine to leak oil and smoke

Smoke coming out from hood, upon looking at it we found oil leak, took to nearest service shop and found cracks in engine head. Brought car to the dealer ship for further inspection and repairs.

When the system thinks there might be a collision it initiates a hard braking even when there is enough space to avoid a collision. Multiple times, the car behind me had to do a hard break as well not to hit me from behind. A google search revealed multiple people complaining of similar issue. The system brakes too extremely aggressively (drops speed from 30 MPH to 5 or less MPH almost instantly stopping/causing skidding) even at its lowest setting. When I address with Mazda Service Manager he advised "it's supposed to do that" and if I choose to I can manually disable the feature each time I enter the vehicle. Note, I am currently driving a loaner car 2023 Mazda CX-5 and have not experienced the same issue, so it does not seem "it's supposed to do that". I have been driving the loaner for 4 weeks and not once have I experience this issue - the system has never engaged except for once where only the Warning light appeared on the display but the braking did not engage. Whereas my vehicle engages this anti collision braking nearly every day I drive it. This system has almost caused more accidents than it protected me from them.

Noticed the smell of burning oil in the cab on 30 mile drive. No warning lamps or other symptoms; vehicle continued to operate normally. After parking and inspecting the engine for the burning smell, noticed oil dripping from underneath engine bay and a pool of motor oil was forming on the ground underneath the vehicle. The next day, vehicle was brought to local Mazda dealer for inspection. They diagnosed the cause and stated the engine needs a cylinder head replacement. Oil leakage was so prolific, if this were to occur during a long distance drive, the engine would have lost all of the oil and stranded motorist - safety concern. Cylinder head failure is a known issue (Mazda TSB [XXX] ) with this engine. This known safety issue should trigger a recall. At minimum, the repair should covered by manufacturer for life of vehicle.

We were at a stop light and we were rear ended by a Lexus SUV. We're assuming she was going 45mph + but we're not too sure yet. I couldn't figure out why myself, the drive of the car that was hit, had such a horrendous neck ache after being hit. I turned around & saw that my headrest had been completely ripped out of the seat itself, providing no support for my head and/or neck on impact. I can't find any information of if this is on purpose, as a safety feature, or if the headrest failed.

Cracked cylinder head with oil leaking. There were no warning from my car prior to a diagnostic test. The car has a very strong rubber burning smell and white smoke comes out from the engine part before I took my car back to the Mazda Dealer. From a quick search, the cracked cylinder problem seems widespread with the 2018-2021's Mazda Cx-5. Took the car back to the dealer and dealer replaced the head cylinder and gaskets. There were no warning from the car.

the infotainment LCD screen has "Ghost Touch" issue. The screen randomly appears to move around as if a ghost is touching the lcd touch screen. After researching online this is a common problem Mazda will not address.

The contact owns a 2019 Mazda CX-5. The contact stated while driving approximately 65 MPH, the air bags warning light illuminated. The vehicle was taken to a local dealer to be diagnosed; however, the contact was not provided information the diagnostic test results. The vehicle was not repaired. The contact stated that the air bags warning light was no longer illuminated. The manufacturer had been informed of the failure. The failure mileage was approximately 38,000.

2 weeks ago I noticed an oil leak 2019 cx5 . Riley Mazda of Stamford check and found a cracked on the cylinder head. The cylinder head needs to be replaced cost around $5000. luckily we noticed the leak while car was park. Imagine if the car was on the road. Dangerous things could have happened. Mazda is aware of this situation years ago. A technician Service Bulletin was released by Mazda in 2019/2021 to all dealerships technicians repair guideline and why the cylinder cracks. On the Mazda bulletin it clearly explained a design defect resulting cylinder head cracks. Also Mazda failed to warn cx5 owners about the dangerous situation. On top of everything Mazda refuse to pay the Defect cracked cylinder head that cost around $5000 . I email mazda Numerous times and decline any goodwill repair . Reason is out of warranty. Most Cylinder heads past 200,000 mile mark. Not unless your engine overheats but it not. Mazda should reimburse us owner who paid the repair cost

Smoke started coming from the front end of the car so I brought my car into the Boniface Heirs Mazda dealership for a diagnostic. I was informed by the mechanic that my car has a factory defect and the head of the engine was welded wrong. Apparently this is a known factory defect in the 2018-2019 Mazda CX-5s as I have seen other reports for the same issue. I reached out to Mazda corporate to see if they could help with “after warranty assistance” since this was a manufacturers issue and I do everything to maintain my car properly. They denied any help and do not plan on recalling the part. I had no warning lights just smoke pouring from the font of my car. I do not understand how this is not considered a safety issue. I’m lucky my car didn’t catch on fire. I now have to decide between spending $5000 to fix the engine head or to sell my car and find a new one.

While driving down the road my Mazda CX-5 continues to just stall and the engine light turns on and the safety features turn off. I was driving down a road in town and the engine started stalling as I came to a red light and slowed the engine shut off and I was almost hit from behind. It took several attempts at starting before the car would start. This has now happened for the past 3 days and is happening more and more frequently. I do not have any other means of transportation and after attempting to get the dealership to check due to the recalls on the Mazda CX-5 for fuel pump failure and the mechanic saying it appears the fuel pump is bad the dealership refuses to attempt any repair because the VIN is not listed in the recall at this time. This is a severe safety problem because if it stalls in traffic I will be in an accident as I have no ability to maneuver the vehicle when it stalls to get out of the way of vehicles approaching. If this issue isn't resolved it is going to cause injury to myself or others. People have had to swerve into the path of other vehicles to keep from hitting me when it stalls, which is eventually going to result in harm to others and/or myself and family.

purchase a new 2019 cx5 at riley mazda stamford. after 3 years and with 88t miles ,the head gasket cylinder gasket needs a replacement for $4500. while searching i read the same complaints from 2019 cx5 owners about head gasket blownout. a TSB Technician Service Bulletin was release by Mazda in 2019 regarding this issue and another one 2021 with affected vin numbers included , this car is un drivable , oil leaks like water falls and burning smells along w it

Crack in Cylinder Head at only 67,000 miles, leaking fuel into exhaust system, causing smoke while driving. Multiple shops consistently mentioned seeing this problem with this year, make and model. Due to 60k powertrain warranty, no fixes are being covered by Mazda

The touchscreen randomly turns off, has “ghosting” where the touchscreen will do things on its own. Doing research I found this is a known issue with Mazda touchscreens and had a recall for 2013-2016 models. 2017+ models experience the same issues. This seems like a safety issue as many of the safety options and toggles are within the infotainment center.

After noticing a burning oil smell following an oil change, I brought my 2019 Mazda CX-5 Touring (42,000 miles) back to the Mazda dealership assuming an issue with the fuel filter. There were no warning lights/messages associated with the smell. The Mazda dealership inspected the vehicle and indicated the leaking oil was due to a cracked cylinder head, which was known issue covered under Mazda's warranty.

Vehicle warning system notified operator of engine overheating. Operator took vehicle to repair shop where mechanic identified a cracked cylinder head. Mechanic mentioned no reason crack should have occurred, potential manufacturer defect with forged aluminum casing.

The computer monitor on the vehicle seems to have a mind of its own. After talking with the service rep they actually have a name for it because it is happening to many owners "Ghost Touching. The car tends to call people on your contact list automatically, change radio stations, move from settings all on its own. I feel it is dangerous because it will all of a sudden call someone and then you are trying to stop it and it does not disconnect and your focus is now taken off of the road and driving. Even if you try to turn the monitor off it turns on by itself. I was told there is no way to disconnect it and I would have to pay to have it fixed on a car that is only a couple years old. They know this is happening quite a bit, Mazda corporate would not do anything and I think it should be a recall issue before someone gets in an accident. This happens many times in one driving day.

Wife was 30 weeks pregnant when airbag fault displayed. Was in fact a defective driver side airbag.

On my Mazda CX-5, the auto-folding side mirrors began failing to open fully, resulting in poor visibility. It is possible that the mirrors may become fully folded and unable to open resulting in compromised awareness when driving. It is not possible to force the mirrors open without risking damage to the internal mechanism and no guarantee the mirrors would stay open. This seems to be related to Bulletin No.: 09-011/20, however service centers are declining to fix this outside of warranty. There are numerous cases of this happening documented on Mazda forums and online groups, and the service associate admitted to me that just the day before someone had come in for an identical problem, but the owner declined to pay for a nearly $2000 fix.

Windshield cracks too easy on 2019 Mazda CX-5. The car is 2019 and has already had 7 separate incidents (Crack and or Chip). Mazda knows of the problem and there are many Mazda customers that have reported problems with the integrity of the windshield. It's very concerning because it could be a safety issue if the windshield cracks so easy especially with all the objects and debris on the road that bigger vehicles like trucks kick up. I don't feel safe.

Oil light came on. Cracked cylinder head causing oil to leak in rear of engine onto exhaust system. This gives off burnt oil smell into vehicle passenger area. Concerned this could cause fire. Vehicle was taken back to dealer where it was found to be leaking. Dealer stated will order new cylinder head but does not know when it will be in. dealer stated drive vehicle until part comes in.

The 2019 Mazda CX-5 has a design and manufacturing issue with its infotainment system. The screen activates functions without pressing the screen or activating the joystick. It changes the station, calls by phone and changes important security parameters such as braking assistance. Reflecting a notice on the main board. There are thousands of cases of affected vehicles. This problem is a serious situation that Mazda must correct immediately, because it distracts the driver and changes extremely important safety parameters. The infotainment system is not just for listening to music or making calls. This system manages many aspects of vehicle safety. Mazda replaced the part with a new part number for obvious reasons. All vehicles that have the affected part must be replaced with the new part number to avoid possible accidents. The defective part is K123-61-J0A. The replacement is K123-61-1J0C. Thank and best regards.

The cylinder head is “seeping” out oil Not a crack and not gasket failure Dealer service advises they could help us get it fixed IF ONLY we had receipts of oil changes. We do not because we change the oil ourself.

My 2019 Mazda CX-5 has 61,500 miles on it and has a cracked cylinder head and has a massive oil leak. I took it to the dealer and they are aware of this issue but told me Mazda hasn't so far made a recall. No warning lights went off and i lost 1 quart of oil over a 30 mile drive. Upon Acceleration the engine could seize and could cause a crash. A fire is also not out of the question as the parts in the engine area are hot and oil can catch fire. Mazda declined to pay for the total cost of the repair but did partially pay for some of it. They should be held accountable for the lousy design and it's only a matter of time someone will have an accident because of it.

UNKNOWN While stopping the radio system (which can not be powered off) will change and go to other apps. This causes the driver to take their eyes from the road and hand from the steering wheel to press buttons to get the radio system under control. When the radio does this it often goes to the settings and changes the navigation voice volume to the loudest it can go essentially frightening the driver and causing them to look away from the road and divert their attention to the radio system. This occurs every time the vehicle is driven and often occurs when hitting the brakes.

I purchased this vehicle used and with 35,000 miles on it, took it to Mazda for an oil change. The windshield wipers never seemed to work that well, and Mazda told me that the actual wiper arms (not blades) were installed on the wrong sides of the windshield (ie: Driver arm was on the passenger side, and Passenger arm was on the driver side). I removed them arms and reinstalled on the correct side and now the wipers work fine. I am reporting this as I assume they were installed incorrectly when the vehicle was manufactured, and I'm concerned that other vehicles may be affected.

The screen in the middle of Mazda vehicle starts selecting menu, change the radio station or selects/plays whatever it likes. It suddenly activates some functions on its own. Most likely similar issue as in this document - https://static.nhtsa.gov/odi/tsbs/2019/MC-10164268-0001.pdf This is dangerous for the driver as the automatic change in the screen and menu items distracts the driver which may cause accident and put life in danger. This is generic problem and searching on the internet, lot of people are suffering with this issue. When the issue started last year, we thought this is something random occurrence and will go away by itself but with the time, this has gone worse. Now looking in the internet we came to know this is actually an ongoing issue.

While driving the vehicle at highway speed, the check engine light came on at just under 28,000 miles. I took the vehicle to AutoZone, who did not come up with a code; however, I took it to the dealer with engine code P0126, which stands for insufficient coolant temperature. Apparently, there is a flaw in the coolant control valve, but the part is on backorder until June or July. In the meantime, my gas mileage is awful, my car takes forever to warm up, and the engine performance is awful and the vehicle is not safe to drive at highway speeds. This really merits a recall and a whole lot more attention from a company that was Consumer Reports most reliable brand for 2022. I am really disappointed with Mazda and how they have handled this situation and they have permanently lost my business over this.

The contact owns a 2019 Mazda CX-5. The contact stated while driving at approximately 75 MPH with the sunroof opened in the vent position, and the rear windows and driver's side and passenger windows opened, the contact stated he heard an abnormal sound like a gunshot and the sunroof glass shattered, and pieces of glass entered the cabin. The contact pulled over and observed that a hole measuring approximately 12 inches by 6 inches had opened in the sunroof. The contact noticed that the glass surrounding the hole had an uplifted edge of approximately 2 inches around the hole. The contact had not taken the vehicle to a local dealer or independent mechanic. The vehicle had not been repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 48,000.

The Infotainment System has consistent "ghost touching". Not only is this a distraction while trying to drive it is changing the safety settings and display settings available in within the system such as ADAS settings and MPH\KMH speedometer options. Other less-severe options are consistently changed as well such as navigation volume etc. The problem is easy to reproduce, just need to start the car. I just paid $300 for a full replacement of the screen from Mazda, along with an update and the problem not only persists but is worse. The problem got progressively worse but there were no light indicators etc.

The contact owns a 2019 Mazda CX-5. The contact stated became aware of engine oil on his driveway. The contact stated that while driving and coming to a stop, there was an abnormal oil burning odor inside the vehicle. The contact stated the check engine warning was illuminated. The contact had taken the vehicle to an independent mechanic who diagnosed that there was an oil leak coming from the cylinder head and determined that the cylinder head needed to be replaced. The independent mechanic researched online and related the oil leak failure to Mazda Service Alert Number: SA-031/21 (Engine and Engine Cooling). The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 89,000.

the infotainment system is acting up and making its own selections, if im sitting parked and my call history is up it will sometimes click a random number and start calling that number. It will scroll and make random selections on screen

I drove my wife to work and noticed that the car was stuttering and had weak acceleration. I parked in my garage and a couple of hours later returned to see a massive oil leak on my driveway, I had to tow the car to the nearest dealership where a cracked cylinder was diagnosed. There was also a terrible burning smell. If the massive leak happened on an acceleration ramp or on the highway there could have been an accident.

My vehicle appears to have what is known as the "ghost touch". The radio ends up clicking random things, skips songs, goes to the maps and zooms all the way in. This puts the driver at risk if they are distracted by what is happening to their radio. I informed the dealer, but they thought it just needed a software update. The issue continued even after the update that I had to pay for. Warning lamps to not appear, and it happens at random times, it's never consistent. It's been happening for a while now, probably over a year, and months after I had purchased it as a used car.

Known Issue. Mazda has issued a TSB, but will not extend Warranty or pay for needed repairs. Infotainment Screen changes and Beeps by itself. Screen is peeling as well. 2019 Mazda CX-5 Infotainment Technical Service Bulletins TSB Number: SA-041-22C NHTSA Number: 10226930 TSB Date: November 22, 2022 Date Added to File: December 1, 2022 Failing Component: Equipment:Electrical:Infotainment Summary: Some customers may complain about infotainment center display: * ghost touch * DTC b108e:04 may be stored (touch screen operates by itself) * surface peeling * DTC b108e:04 may be stored * spider cracks * white dots

My 2019 Mazda CX-5 automatically applied the brakes while the car was on cruise control traveling at 65 mph on a highway, and there wasn't a car or any object in front of me or to either side of my car. The car applied the brakes firmly and brought the speed down quickly and dangerously. I quickly depressed the accelerator to get the car back to highway speed to avoid a rear-end collision. This issue has happened 3 times in the past 2 weeks, all while traveling at highway speeds on cruise control for an extended period of time (hours). I believe this is the same issue with the Mazda Smart City Brake Support system that led to a recall of 2019-2020 Mazda-3 vehicles. My Mazda CX-5 is out of warranty and the dealer stated it is not covered by the recall.

After purchasing this vehicle I started noticing that as I accelerated from a stop the transmission would shift hard into 1st gear and 3rd gear. This is also occurring during deceleration as if the car brakes I'm stages due to the downshifting hard. The dealership has refused to look into the issue. They have refused to add the notes to my vehicle records in effort to avoid accountability.

Unknown. The engine started to stall as I was driving and the gas pedal wasn't working. The car shutdown after reaching 0 moles per hour and it would jerk when I tried starting it. The car had enough fuel, battery and was service a month prior. The car would not start and had to wait a few hours to try again. The issue is similar to the recall this model has but when I checked my VIN is all cleared . Please Help.

The contact owns a 2019 Mazda CX-5. The contact stated that her daughter received notification of NHTSA Campaign Number: 21V875000 (Fuel System, Gasoline) and scheduled an appointment for August 1; however, upon arrival at the dealer she was informed that the part was not available. The contact stated that the dealer had been called several times and it was confirmed that the part was not available and that the contact would receive a call back. The manufacturer was not made aware of the issue. The contact had not experienced a failure. Parts distribution disconnect.

While I was driving on the highway at 60 mph the glass sunroof exploded with a loud bang. Luckily the sunroof shade was closed, otherwise shards of glass would have fallen on me causing injury and possible loss of control of the car. I immediately reported the incident to my insurance company and the next day brought the car into the Mazda dealership. The service manager claims he never heard of sun roofs exploding and there were no outstanding recalls on sunroofs. I left the car at the dealer for further inspection by Mazda.

The contact owns a 2019 Mazda CX-5. The contact received notification of NHTSA Campaign Number: 21V875000 (Fuel System, Gasoline) however, the part to do the recall repair was unavailable.

VIN tool confirms parts not available. The consumer stated that Mazda still have not performed the recall for the vehicle.

heading south doing 70 mph on 95 in the far left lane on a rainy day ....came over a hill and started to hydraplayne.....seems like the automatic pilot took the car over ,,,,,i lost the fight with the steering wheel and did two 360s all away across 4 lanes of traffic to the grass inbankment on the other side,,,,,lucky to be alive ......very lucky

P225/55R19 99V: On November 2, 2021, I was slowing down at a stop light. I was about 5 minutes away when my tire separated. I heard my car make a big sound and drop to the ground on the front passenger side. I lost control and hit the side of the curb, but I was able to pull my car over to a side road safely. It took over 3 hours for the tow truck driver to come, but when he did, he said he hasn’t seen one like this in a while, but it is a defective tire. The middle of the tire was a clean separation from the sides. If it was a tire blow-out the sides of the tire would be uneven, but this was as if the glue that held it together was loose, and the middle just fell out. The tow person tried to take the spare tire and he found that it was incorrect. My car a had 25,000 miles and I bought it new from the dealership and they made the mistake of giving me the wrong tire. Mazda corporation later had to replace it. Mazda dealership told me to contact customer service to discuss the tire. I emailed customer service several times and it took nearly 2 months for them to answer. I called several times, and I would wait on hold and they would hang up. When I finally got someone on the phone, she told me that Mazda warranty does not cover the tires. That is completely in the hands of the tire manufacturer. I contacted Toyo Tires and waiting a month for a response, I was contacted by a customer service. He mentioned that photos and videos were not enough, but that I had to send the tire back. I mentioned that Mazda did not tell me to keep the tire and when they replaced it, they disposed of it. I received a letter stating that there is nothing they can do. My car is a 2019 CX-5 and in the same year the CX9 was recalled for tire separation issues from the same company. I am extremely frustrated how Mazda and Toyo has handled this entire issue.

The contact owns a 2019 Mazda CX-5. The contact stated that the center display was malfunctioning. The contact stated that the rearview camera turned off inadvertently or failed to operate as intended while reversing the vehicle. The contact also stated that the screen display brightness would decrease independently. Additionally, the contact stated that the exterior lights would malfunction due to the failure. There was no warning light illuminated. The vehicle was taken to the dealer where the computer software was updated. The dealer also informed the contact to remove the Mazda navigation SD card. However, the failure persisted. The vehicle was taken to the dealer where it was diagnosed that the center display touch screen panel had failed. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that they could not assist as the VIN was not included in any recalls. The failure mileage was approximately 40,000.

Tuesday, 5/3, I was parking my car in the New Leaf Grocery parking lot in Aptos, CA. I pulled into the lot and made slow right into an available space. I had my foot on the accelerator, tapped down on it gently to ease into the space. My car lurched forward at such high speed that I was unable to remove my foot from the accelerator. I swerved to the right as the car went over a partition and hit another parked car on the other side of the partition. My airbag did not activate. I've replayed the experience in my mind and tried convincing myself that this could have been a matter of human error on my part. I am beyond convinced that what I experienced yesterday was a case of sudden unintended acceleration. I am concerned and afraid to drive my car now. Had circumstances been different, someone could have been killed. Had I not swerved right, I was headed to crash into a building. I called 911 and since no one was hurt there was no Police report. To address questions set-out above: Speed control (sudden unintended acceleration) and air bag failed My safety and the safety of others was put at risk As of yet the problem has not been reproduced however there are a great number of reports related to unintended acceleration (however not acknowledged as a problem by Mazda) I plan to have my Mazda inspected by a local dealership service center There were no warning messages or symptoms in advance of the incident occurring I've owned my Mazda for 3 years and never experienced anything like this. I have never had a car accident to date.

When driving at above 60-70mph in windy conditions, the car makes a squeaking noise that appears to come from the front left side of the car-- near the driver side window/mirror region. That is quite scary as it coincides with the sideward movement caused by the wind and gives a sense of losing control of the car. Mazda Europe has reported something similar but Mazda USA has not done anything about it.

Mazda recall 5321K NHTSA recall 21V875 has been open since Nov 2021 and notification by letter not received until Jan 2022 stating that a fix may be available by summer 2022. Meaning I am driving a vehicle that may stall at any time possibly causing a crash. This is unacceptable from a safety standpoint. NHTSA needs to apply pressure on Mazda to resolve this ASAP or provide loaner vehicles to those customers at risk.

On interstate 90 while driving at 75 mph under cruise control I passed an 18 wheel truck on a curve. With no cars in front and two following, the car without warning braked heavily and control screen flashed warning BRAKE. The car immediately behind braked and veered on the bearm to avoid me. I stepped on gas to override the brakes and avoid an accident.

The contact owns a 2019 Mazda CX5. The contact received notification of NHTSA campaign number 21V875000(Fuel System, Gasoline) however, the part to do the recall repair was unavailable. The local dealer was contacted and it was confirmed that the part was not yet available and would not be available until mid-summer. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact stated on two separate occasions while driving at undisclosed speeds, the vehicle stalled without warning. After a restart, the vehicle operated as designed. The contact was concerned that the failure might occur while driving on a busy freeway. VIN tool confirms parts not available. The failure mileage was 5,000.

I believe my car has been affected by the FDM fuel pump replacement recall (#5321K). My car has stopped working. Parts are currently unavailable. What can be done as I need my vehicle for work?

The "Passenger Air Bag is not active for passenger' warning light was constanstly showing in the dash panel even when nobody was sitting in the passenger seat nor any object was sitting on the seat. The problem was "solved" by the dealer under the car's warranty. They said something about dirty contacts in the seat wiring. Now the warning light is back and my SUV's warranty period is over.

Safety recall just received for my car. Fuel pump failure may result in engine failure increasing risk of crash. Repair parts not available. It is expected parts may be available summer 2022. I will be driving cross country to return home to NY from AZ in March. What am i supposed to do?

My 2019 Mazda CX 5 with 25000 miles stopped moving on my way home. It was towed to John Kennedy Mazda in Conshohocken PA on 11/22/2021. It was diagnosed with a failed transmission and still awaiting replacement as of 1/3/22.

At high speeds, air enters through the front windshield from outside of the car and into the cabin, making a whistling sound. It seems the problem is with the windshield design or fit.

I was driving on the highway, at about 65 mph. The engine lost power and the car began to slow down. It did not respond to the accelerator, but the power was still on. I was lucky enough to be able to pull over to the shoulder without colliding, but it was extremely fortunate that no cars were obstructing me at the time. I put the car into park once stopped and turned the engine off. I tried to restart but the engine did not turn over and several warning signs came up on the dash and the car emitted irregular dinging/beeping noises before going silent (I do not recall specifically, but I believe the check engine and/or battery indicator lights came on) The hazards worked, also the interior lights. But I was stranded in a remote area in complete darkness on a very narrow shoulder with large trucks whizzing by. A CHP officer appeared eventually and expedited a tow truck, which brought me to the nearest Mazda dealership 100 miles away. It was midnight by the time we arrived. Both the tow truck driver and the technician (the next morning) were both unable to jumpstart the car. Engine would not turn over at all. The technician opened up the engine and sent reports to Mazda. We are waiting to hear back but they would not give me a loaner vehicle without knowing the cause of the failure. Very relieved I was not hurt but also very upset at the chance I could have been.

At about noon on 12/19/21 I was approaching the Tappan Zee (Mario Cuomo) Bridge in New York State going west. My car briefly stopped accelerating when I put my foot on the gas pedal but then continued on as normal. No warning lights or other signs of trouble appeared, and I continued onto the bridge and was in the center lane. There was moderate traffic on the bridge. Suddenly, my car started shaking and slowing as if the brakes were being pumped (although I did not put my foot on the brake), and the messages "Front Radar Sensor System Malfunction" "Forward Smart City Brake Malfunction" and "Smart Brake System Malfunction" all flashed on the dashboard screen. My husband turned on the emergency flashers and took a photo of the screen. The car continued slowing down and shaking no matter how hard I pressed the gas pedal. This created an incredibly dangerous situation; I had to get over to the right lane as we continued losing speed, and find somewhere safe to pull over once we got off the bridge. A car or truck going at a normal speed could have easily hit us and caused a catastrophic crash on the bridge. If I could not get out of the center lane quickly, at the rate the car was slowing down, it would have come to a complete stop in the middle of the roadway. I was able to merge right, get across the bridge and get to an exit, all as the car continued lurching and slowing down. At the bottom of the exit, there was a red light; I stopped and turned the car off and back on again. When I tried to accelerate out of the stop, smoke began pouring off the wheels. The car moved across the intersection at a few miles per hour and I was able to pull over safely on the right shoulder on the other side of the intersection. I had only bought the car the previous day, less than 16 hours before the incident. I called Mazda Roadside Assistance and the dealership; the dealership told me to have the car towed to their service department, so I did.

Almost every time you drive at speeds of 75 mph+ or when there are strong winds on the highway, there is a whistling noise that comes from the drivers side door frame. This has been reported online in many groups. There are even video's with the exact problem available. NHTSA ID Number: 11429312 goes into the details in depth and I can say that my experience is exactly the same as theirs.

There was a warning "chime" and then this message appeared on the instrument panel. "Front Radar Malfunction". The car was in the left lane on the PA turnpike going approximately 73 miles per hour. The car immediately began a rapid deceleration after the warning "chime". Automatic braking activated. The driver could not accelerate. Traffic was heavy with a trailer truck to the right and cars behind. There were no vehicles in front of the decelerating car. The vehicles behind were able to slow and avoided collision. We were forced to pull over in a very narrow center medium next to a large concrete divider. It was a very dangerous place to stop. The engine was turned off for approximately a minute. When it was started there were no messages and the driver had full control of the car. The car is available for inspection. The dealer will be contacted tomorrow. The car has been in service for 23 months and has been driven 12,200 miles. The road surface was wet from recent rain and the car had been driven through a downpour with water pooling on the road approximately 15 minutes before this incident.

The contact owns a 2019 Mazda CX-5. The contact stated while driving 40 MPH with the accelerator pedal depressed and shifting from second to third gear, the engine revved up, hesitated, and lost motive power. The contact was able to restart the vehicle. The check engine warning light was illuminated. The contact also stated that the low-beam headlights were inoperable. There was a clunking noise detected while making a three-point turn. The vehicle was taken to the local dealer and the mechanic diagnosed that there was an electrical failure. The vehicle was not repaired. The manufacturer was notified of the failure however, no further assistance was provided. The contact stated the failure was related to NHTSA Campaign number 19V497000 (Engine, Power Train). The failure mileage was approximately 1,000.

1) It happened last week on 8/30, when I drove back home after work at night. After I parked my vehicle at the driveway and I had noticed there's smoke going into the cabin through the vent. The smell was very bad, it smells like burning rubber/plastic type. Then I went underneath the car and checked, the oil dripping out from the plastic panels where the oil pan is. Next morning, I jacked the car up and have a deeper inspection. I have notice the oil actually leaking from the Timing belt/chain cover area. I immediately called local dealership @ Putnam Mazda and drove it in for service on 8/31. When I arrived to the service department, my whole front end was full of smoke coming out from the hood. After a hour of inspection, service advisor told me that my car is having a blown cylinder #3 and oil leaks from cracked cylinder head. They will have to order a new cylinder head from Japan for my replacement, which will take more than 2 weeks or even longer due to part shortage. This is ridiculous!!! My car only have 21,500 miles on it, and it's a 2019 model year. The advisor told me they had quite a few were having the same issue. I guess he doesn't want to give me the exact numbers. But this is a safety concerns for other Mazda customers as well. I guess it has to do with the cylinder deactivation they put into the engine which cause this problem. The recalls that they had last year was not a fix or cure. 2) This is a safety concern and putting my life on risk, the oil leaks might cause fire or create accident on the road while operating. The smoke that I suck into my system may cause permanent damage to my lung and my health concern. 3) Problem had been confirmed with dealership. Mazda should declare a recall. You can't just wait for someone have an accident or cause their life to correct the issue. 4) The vehicle is at the servicer dept. and been inspected. 5) This is critical, I don't have any engine light or any indication. Even my scanner detected no code.

The contact owns a 2019 Mazda CX-5. The contact stated while driving at approximately 20mph the vehicle would brake suddenly. Which resulted in the contact sustaining whiplash and sought medical treatment. The contact stated Brake warning message was displayed. The vehicle was not diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 35,000. The VIN was not available.

The center infotainment system operates by itself when driving at a low speed. The screen will automatically enter menus, place calls, and select items without any sort of input from the driver or passenger (ghost touch). The control knob, which is used to navigate the center screen, will not be functional whenever this happens. This ghost touch issue happens periodically, sometimes it goes away and sometimes the problem returns. Whenever the screen places calls or enters menus by itself, the driver is being distracted from the road and will have to focus on canceling whatever action the infotainment automatically decided to do. For example, I use Apple CarPlay for navigation but sometimes the screen will operate other functions by itself - I will have to manually click back to the navigation screen every time. A similar issue was found in the 2014-2016 MY of the Mazda3, which uses the exact same infotainment and controller setup as in the CX-5 products. I have provided a link to the relevant service bulletin here: https://static.nhtsa.gov/odi/tsbs/2019/MC-10164268-0001.pdf The system has not been examined by the manufacturer nor have there been any types of warning messages or lamps within the vehicle.

Oftentimes when driving at speeds of approximately 80mph or more, a loud whining/whistling noise appears. It appears to be coming from the area of driver side front door, passenger side front door, both front doors simultaneously. The issue has an earlier onset in the presence of crosswind, or headwind. I was able to record several videos where the noise can be heard very clearly. Some of these videos have been posted online: https://vimeo.com/547826873 https://vimeo.com/manage/videos/580602909 and the links have been shared both with my local Mazda dealership (Oak Tree Mazda by DGDG in San Jose, CA: 4250 Stevens Creek Blvd, San Jose, CA 95129) as well as with Mazda of North America. However, my complaints have been ignored as the dealership keeps stating that they are "unable to duplicate problem". There are several threads on two Mazda owners forums that describe this very issue with Mazda CX-5 in USA, Canada, as well as in Europe. This video from an owner in Germany shows the very same issue: https://www.youtube.com/watch?v=zykyoCIsItc&t=204s https://www.mazdas247.com/forum/index.php?threads/2019-cx-5-signature-whistling-noise-on-highway-or-high-speeds.123868506/page-2#post-6727077 https://www.mazdaworld.org/threads/cx-5-2018-version-high-pitched-squeal-whistle-like-noise.337073/#post-754625 According to one of the forum members, a Technical Service Bulletin (TSB) R084/20 to address this issue has been issued by Mazda in Europe and Russian. The root cause has to do with door trim seals. Under the "CASUE", this TSB reads, "When driving under following conditions, a negative pressure generated on the doors pulls them outside. The counterforce exerted by the weatherstrips mounted on the doors is lower than the sucking force, resulting in weatherstrip vibration. -The vehicle is exposed to a side wind while driving at a speed higher than 160km/h -The vehicle is exposed to a strong side wind while driving at a speed higher than 120km/h."

The contact owns a 2019 Mazda CX-5. The contact stated that on five separate occasions, intermittently there was an abnormal grinding noise detected underneath the hood. The contact stated that while driving 65 mph, the vehicle inadvertently decelerated to 20 mph. Additionally, while accelerating the vehicle slowed down without warning. The vehicle was taken to an independent mechanic where no codes had been detected. The vehicle was towed to the local dealer where they were unable to duplicate the failure. The vehicle was not diagnosed nor repaired. Additionally, the vehicle was towed to Sport Mazda North (400 N US Hwy 17 92, Longwood, FL 32750, (407) 339-4777) where they were unable to duplicate the failure. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was approximately 17,000.

When the system think there might be a collision and initiates a hard braking even when there might be enough space in front of you. Multiple times, the car behind me had to do a hard break as well not to hit me from behind. This also happens when switching lanes. As you are in the middle of switching, if sometimes thinks you are getting to close to the car in the original lane and it starts a hard break. Since I’m in between lanes, it causes the car on the other lane to do a hard break also, almost causing a chain accident. A google search revealed multiple people complaining of that. The system is too aggressive even at it’s lowest setting. Mazda informed me I can only turn it off one drive cycle at a time. This system has almost caused more accidents than it protected me from them.

Driving on highway, cruise control ser to 82, no cars in front. The car suddenly jolted twice, engine light and battery light comes, lost of power. Pulled over to shoulder in the middle of nowhere in Nevada. Tried to start the car, engine won't turn on, starter just kept cycling. Veh temp was just below 210 with a 1/4 tank of gas. Called dealership and service person asked is to use key to turn on car, no change and provided no other solution other than to take to dealership with the closest one being over 300 miles away. We decided to unhook and rebook the positive side of battery. Car restarted and currently driving it home as I write this complaint. 600 miles overdue for maintenance (by date due on July 26, 2021) and was scheduled upon return from trip which at the time should be approx 1000 miles over due.

THE CONTACT OWNS A 2019 MAZDA CX5. THE CONTACT STATED THAT HE NOTICED AN OIL LEAK ON TOP OF THE ENGINE. THE VEHICLE WAS TAKEN TO COMPASS MAZDA (200 DOLSON AVE LOT A 204, MIDDLETOWN, NY 10940: (844) 258-3818) TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE MASTERCYCLER NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 63,000.

BROUGHT IT IN NOV 2020 REGARDING SMELLS AND ENGINE ISSUES AS WELL AS ALIGNMENT. NEITHER WERE TAKEN CARE OF. THEN MARCH 2021,ENGINE WAS LEAKING FLUID AND SMOKING, AND THE ENGINE NEEDED TO BE REPLACED AT 20K. DID NOT PROVIDE A RENTAL UNTIL LATER THAT WEEK. AFTER A MONTH, I GOT MY CAR BACK. AFTER LEAVING THE ENGINE CONTINUED TO SMOKE, BROUGHT IT BACK. GAVE NO RENTAL. DEALER SAID IT WAS LEFT OVER FLUID FROM WHEN THEY REPLACED IT. CAR IS STILL HAVING ISSUES WITH THE ENGINE AND SMELLS. UNDER SHIELD FELL OFF AND NEEDED TO BE REPLACED TWICE.TIRE PRESSURE WAS GOING OFF AND BROUGHT IT IN TWICE FOR THEM TO SAY THEY CANT FIND WHERE THE SLOW LEAK IS OR WHY SO THEY WOULDN'T FIX IT EVEN THOUGH I HAVE THE MAZDA INSURANCE FOR TIRES.

I HEARD A VERY LOUD BANG, SOUNDING LIKE A GUNSHOT THAT WENT OFF, WHEN THE SUNROOF ABOVE MY HEAD VIOLENTLY SHATTERED WHILE I DRIVING TO WORK. I ALMOST LOST CONTROL OF THE CAR AND GOT COVERED WITH PIECES OF GLASS. THE GLASS SCRATCHED ME ON THE FACE, CLOSE TO MY EYE. I AM IN SHOCK AND I AM STILL FINDING SMALL PIECES OF GLASS ALL OVER MY BODY EVEN AFTER TAKING A SHOWER.

REAR PASSENGER SEAT REST BEHIND DRIVER SEAT IS RATTLING AND DOES NOT LOCK TIGHT. THIS HAPPENS WHEN PASSENGER IS SEATED.

WINDSCREEN STRESS CRACK 12 - 15 INCH UPPER END. NO VISIBLE EXTERNAL DAMAGE CAUSE, NO EVIDENCE OF DEBRIS DAMAGE. APPEARS AS MATERIAL DEFECT, MANY SIMILAR REPEATING COMPLAINTS ON THE NET. MAZDA REFUSES TO REPLACE UNDER WARRANTY, REFUSES TO INSPECT.

VEHICLE HAVING SIGNIFICANT DROP IN POWER OUTPUT IN 1ST AND 2ND GEAR WHEN AMBIENT TEMPERATURES BELOW FREEZING. ISSUE RESOLVES WHEN FINALLY SHIFTING TO 3RD GEAR, BUT LACK OF PREDICTABLE RESPONSE WHEN MERGING IS UNSETTLING.

UNINTENDED ACCELERATION - I WAS PULLING IN TO MY GARAGE, HALF WAY INTO THE GARAGE, THE CAR ACCELERATED, WITHOUT FOOT ON THE ACCELERATOR, AND RAN INTO MOTORCYCLE AND GARAGE BACK WALL. THERE ARE TIRE TRACTION MARKS WHERE IT BEGAN TO ACCELERATE UNATTENDED, AND TIRE TREAD FROM MULTIPLE ROTATIONS OF THE TIRE WHERE THE VEHICLE FORWARD MOTION WAS STOPPED BY THE WALL. ANOTHER DRIVER OF THE CAR STATED THAT THE NIGHT BEFORE, WHEN FOOT WAS TAKEN OFF THE ACCELERATOR THE CAR CONTINUED TO ACCELERATE.

VEHICLE DISPLAY ON DASHBOARD, STEERING WHEEL, SHIFT CONSOLE, AUDIO CONTROLS, SEATS ADJUSTMENTS ARE NOT ILLUMINATED. THE LETTERS AND NUMBERS ARE NOT LIGHTED. UNABLE TO KNOW WHICH BUTTONS TO PUSH BECAUSE PRINTING IS SO SMALL AND MANY CONTROLS ARE GROUPED TOO CLOSE TOGETHER. MAZDA CX5 OWNER'S MANUAL IS FOR ALL MAZDA MODELS. THERE IS NO INDICATION AS TO WHAT FEATURE IS INCLUDED ON MY CAR. THIS CAR LACKS LIGHTED DISPLAY AND CONTAINS SMALL LETTERS/NUMERALS WHILEPARKED, MOVING OR DRIVING IN DAY OR NIGHT; MAZDA DEALERS IN TWO DIFFERENT TOWNS REPORT UNABLE TO IMPROVE SITUATION "THAT'S HOW IT IS" .

2019 MAZDA CX-5. CONSUMER WRITES IN REGARDS TO DISPLAYS ON VEHICLE CONSUMER STATES THAT THE DISPLAYS ARE TOO TO SMALL AND NOT LEGIBLE. *LD *JS

THE FUEL LOW LEVEL LIGHT IS NOT TRIGGERED UNTIL 12 MILES OR LESS OF FUEL REMAINING. THE SERVICE BULLETIN PROVIDED BY THE DEALERSHIP, MED CENTER MAZDA IN PELHAM ALABAMA, SHOWS THAT WHEN THE FUEL GAUGE SENDER VOLTAGE FROM THE RBCM AND THE FUEL INJECTION AMOUNT FROM THE PCM BOTH AGREE THAT 2,6 GALLONS REMAIN THE INSTRUMENT CLUSTER POWERS A TRANSISTOR AND TURNS THE LIGHT ON. IN A DISCUSSION WITH THE SERVICE ADVISOR, WE WERE TRYING TO FIGURE OUT IF THERE ARE 2.6 GALLONS REMAINING THEN WHY THE MILES TO EMPTY DOES NOT REGISTER 30-50 BASED ON THE EPA RATINGS FOR THE VEHICLE. WE DECIDED TO DISCONNECT THE BATTERY TO CLEAR ANY RESIDUAL INFORMATION IN THE COMPUTER AND RESET THE AVERAGE FUEL ECONOMY SYSTEM. WHILE DRIVING THE MAZDA CX-5 LESS THAN 24 HOURS AFTER GETTING IT BACK FROM THE DEALER SERVICE DEPARTMENT, THE FUEL LOW LEVEL LIGHT DID NOT ILLUMINATE UNTIL 6 (SIX) MILES TO EMPTY. I EXITED THE INTERSTATE AND DROVE THE VEHICLE ABOUT 5 MILES TO MY HOME. THE MILES TO EMPTY READ 0 (ZERO) WHEN PULLING IN MY DRIVEWAY. I PARKED THE MAZDA AND CHANGED VEHICLES TO COMPLETE MY TASKS FOR THE DAY. UPON STARTING THE MAZDA THE NEXT MORNING, THE MILES TO EMPTY STILL SHOWED 0 (ZERO) WHILE ALSO SHOWING AN AVERAGE FUEL ECONOMY AT 24+ MPG. I THEN DROVE TO THE GAS STATION WHERE 13.573 GALLONS WERE REQUIRED TO FILL THE TANK. THAT LEAVES APPROXIMATELY 1/10TH OF A GALLON UNTIL THE CAR RAN OUT OF FUEL, ALTHOUGH I HAD ONLY TRAVELED 6-7 MILES AFTER THE LIGHT CAME ON. BOTTOM LINE: THERE WAS DEFINITELY LESS THAN 2.6 GALLONS IN THE TANK WHEN THE FUEL LOW LIGHT ILLUMINATED WHICH COULD HAVE CAUSED THE VEHICLE TO QUIT IN THE MIDDLE OF THE INTERSTATE AND WHICH COULD ALSO BE DAMAGING THE FUEL SYSTEM. THE COMPUTERS, PROGRAMMING, AND/OR SENSORS ARE MALFUNCTIONING. THE MALFUNCTIONING FUEL SYSTEM ON THE 2019 MAZDA CX-5 COULD POTENTIALLY LEAD TO AN ACCIDENT.

EXTREME PAINT CHIPPING (DOWN TO THE PRIMER/METAL) ON THE HOOD PRIMARILY. COLOR IS SOUL RED. THE PAINT APPEARS TO BE BRITTLE AND NOT PROPERLY BONDED TO THE PRIMER/METAL. CHIPPING STARTED OCCURRING THE FIRST MONTH AFTER PURCHASE AND HAS CONTINUED TO GAIN MORE CHIPS. THE CAR IS DRIVEN MOSTLY FOR CITY COMMUTING. THIS CAR HAS THE MOST FRAGILE PAINT I HAVE EVER EXPERIENCED. I HAVE PURCHASED A NEW NISSAN, HONDA AND SUBARU IN THE PAST AND NONE HAVE HAD THIS PROBLEM. I HAVE SEEN MANY PEOPLE COMPLAINING ABOUT THIS ISSUE WITH MAZDA ONLINE, IT NEEDS TO BE INVESTIGATED FOR A POSSIBLE CLASS ACTION LAW SUIT.

IN JULY 2019 (APPROXIMATELY 2 MONTHS AFTER DELIVERY) MY 2019 MAZDA CX-5 BEGAN TO DRIVE ROUGHLY AT SLOW SPEEDS- SPECIFICALLY SPEEDS 15 MPH OR BELOW. THE VEHICLE WOULD NOT COAST (EVEN DOWNHILL) AND WOULD SEEM TO SLIP OUT OF GEAR (THIS VEHICLE HAS AN AUTOMATIC TRANSMISSION). MORE SPECIFICALLY, THE VEHICLE WOULD BUCK AND LURCH ON IT'S OWN WITHOUT ENGAGING THE ACCELERATOR OR BRAKE. THIS WAS HAPPENING GOING UPHILL, DOWNHILL AND ON FLAT GRADE. I BROUGHT THE VEHICLE TO THE DEALER AND AT THEIR REQUEST TOOK AN EMPLOYEE FOR A DRIVE SO THEY COULD FEEL IT. THE EMPLOYEE DID FEEL IT, TOLD THE SERVICE MANAGER, WHO THEN TOLD ME THAT, "THEY ARE SUPPOSED TO DRIVE LIKE THAT." HE SAID HE DROVE AROUND ANOTHER VEHICLE ON THE LOT THAT IS THE SAME MODEL AND YEAR, AND THAT IT PERFORMED THE SAME. PLEASE NOTE THAT THIS IS NOT THE SAME PERSON WHO WAS IN THE CAR TO EXPERIENCE HOW MY CAR WAS DRIVING. I PERSONALLY KNOW TWO OTHER PEOPLE WHO HAVE THE SAME EXACT YEAR AND MODEL CX-5. I SHARED MY EXPERIENCE WITH BOTH OWNERS- THEY BOTH TOLD ME THAT THEIR CARS DO NOT PERFORM IN THAT WAY. ADDITIONALLY, I DROVE ONE OF THOSE VEHICLE AND THAT ONE DID NOT PERFORM IN THE SAME WAY THAT MINE DOES. I AM CONCERNED THAT THIS ISSUE IS BEING BRUSHED OFF. THERE IS NO WAY THAT MAZDA WOULD PURPOSELY DESIGN A CAR SO THAT IT JERKS, LURCHES, AND BUCKS AT SLOW SPEEDS. I HAVE READ REVIEWS ON ONLINE MESSAGE BOARDS WHERE OTHERS DO COMPLAIN OF SIMILAR EXPERIENCES, WHICH IS EVEN MORE CONCERNING. THIS POSES A SAFETY ISSUE FOR THE DRIVER, PASSENGERS, AND OTHERS ON THE ROAD WHO MAY BE DRIVING NEARBY. I HAVE AN APPOINTMENT AND WILL BE TAKING THE CAR BACK THIS COMING MONDAY TO TRY AND FURTHER ADDRESS THIS ISSUE, BUT FELT IT NECESSARY TO FILE HERE IN THE CASE THAT FURTHER ACTION NEEDS TO BE TAKEN AT A LARGER SCALE SINCE IT APPEARS AS IF OTHERS, THOUGH NOT ALL, 2019 MAZDA CX-5 OWNERS ARE EXPERIENCING THE SAME. *TR

TL* THE CONTACT OWNS A 2019 MAZDA CX5. THE CONTACT STATED THAT THE ENGINE FAILED. THE DRIVER NOTICED THAT ENGINE OIL WAS LEAKING ON THE GROUND. THE VEHICLE WAS TOWED TO AN UNKNOWN DEALER WHOM ADVISED THAT THE ENGINE NEEDED TO BE REPLACED. THE ENGINE WAS REPLACED. HOWEVER, THE REPAIR DID NOT CORRECT THE FAILURE. THE VEHICLE CABIN FILLED UP WITH SMOKE WHEN THE CONTACT DROVE THE VEHICLE HOME AND THE CONTACT FOUND THAT THE ENGINE WAS LEAKING OIL. THE VEHICLE WAS TOWED BACK TO AN UNKNOWN DEALER FOR INSPECTION. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 7,800.

THE DRIVER'S SIDE MIRROR WOULD VIBRATE EXCESSIVELY AT HIGH SPEED. THE CAR WAS TAKEN TO TWO DIFFERENT DEALERSHIP BUT THEY COULDN'T FIGURE OUT HOW TO FIX THAT. 2019 CX5 EXHIBITS AN EXCESSIVE VIBRATION FROM THE DRIVER-SIDE POWER DOOR MIRROR GLASS WHEN THE VEHICLE IS DRIVEN AT HIGH SPEEDS. THIS CONCERN MAY BE DUE TO A LACK OF RIGIDITY OF THE MIRROR BASE SO THE MIRROR VIBRATES WHEN IT RECEIVES VEHICLE VIBRATION OR WIND PRESSURE. WITH THE WEATHER WARMING UP, STUFF INSIDE THE DOOR PANELS IS EXPANDING WHICH MAGNIFIES THE VIBRATION ISSUE. VIBRATION NOISE IS GETTING WORSE COMING FROM BOTH DOOR PANELS WHEN THE CAR HITS A CRACK, BUMP, POTHOLE, OR WHEN THE RADIO IS ON. MAZDA CORPORATION LACKS INTEGRITY AND REFUSE TO ADMIT THAT THEY HAVE A SERIOUS ISSUE DUE TO THEIR POOR QUALITY CONTROL. THIS IS ISN'T A NEW PROBLEM. 2013-2015 CX-5 HAD SAME ISSUE WITH DRIVER'S SIDE MIRROR VIBRATION BUT THEY ISSUED A RECALL AND THE PROBLEM WAS FROM THE DOOR PANEL WHICH LACKED SUPPORT AND WAS POORLY MADE IN THE 1ST PLACE.

SAT DOWN TO START CAR. AFTER IT STARTED I THOUGHT I PUSHED THE OPEN FUNCTION FOR HATCH..INSTEAD I LOCKED IT . AFTER I CLOSED THE DOOR I SAW THAT THE FOB WAS ON PASSENGER SEAT AND ALL DOORS LOCKED.

MRCC (MAZDA RADAR CRUISE CONTROL) WILL UNEXPECTEDLY DECREASE VEHICLE SPEED WHEN IN A TURN EVEN IF NOT FOLLOWING ANOTHER VEHICLE. SPEED DECREASE HAPPENS REGARDLESS OF VEHICLE SPEED. AMOUNT OF DECREASE IS SEVERE DEPENDING ON "SHARPNESS" OF THE TURN, BUT WILL HAPPEN EVEN ON GENTLE SWEEPING TURNS ON AN INTERSTATE HIGHWAY. BEHAVIOR IS REPRODUCIBLE DURING ALL VARIETY OF DRIVING CONDITIONS.

I WAS DRIVING ON THE FREEWAY ABOUT 65 MILES PER HOUR AND THE THE CAR STARTED TO RUN ROUGH AND THE DASH LIGHTS WENT OUT. IT FELT LIKE IT WANTED TO STALL SO I KEPT MY FOOT ON THE GAS AND BRAKE AND EXITED THE FREEWAY AND DROVE THE SIDE STREETS HOME. THE PROBLEM DID NOT HAPPEN AGAIN SO FAR.

THE VEHICLE WAS PARKED OUTSIDE, BEHIND MY HOUSE OFF OF AN ALLEY IN A PRIVATE PARKING SPACE WHERE IT HAD BEEN UNMOVED FOR THREE DAYS. IT HAD SNOWED OVER THE PAST TWO DAYS. THE TEMPERATURE WAS IN THE 20'S. THE CAR IS TWO MONTHS OLD (1171 MILES). I RAISED THE REAR HATCH TO RETRIEVE A SNOW BRUSH. REAR HATCH CLOSED. I STARTED TO WALK TOWARDS THE PASSENGER DOOR WHEN I HEARD A LOUD CRACKING SOUND. THEN THE REAR WINDOW SELF-DESTRUCTED. IT JUST FELL TO PIECES. I DO NOT WANT TO DWELL ON THE SERIOUS PROBLEMS THIS MIGHT HAVE CAUSED IF THE SELF-DESTRUCTING WINDOW HAD OCCURRED 10 MINUTES LATER WHEN I WAS GOING TO BE DRIVING ON A HIGHWAY.

IT WAS 17 DEGREES OUT AND THE FRONT WINDOWS WOULD NOT ROLL DOWN. THEY WERE NOT LOCKED. WHEN IT GOT IT INTO MY WARM GARAGE AND I LET IT WARM UP (NOT RUNNING) FOR 15 MINUTES, THEY ROLLED DOWN. I HAVE HAD THE CAR A MONTH AND THIS IS THE COLDEST ITS BEEN SINCE I'VE HAD IT. I WAS AT A DRIVE THRU IN PARK WHEN THEY WOULD NOT ROLL DOWN.

ON MONDAY, NOVEMBER 25, 2019, AS I WAS APPROACHING MY HOME, I ACTIVATED MY GARAGE DOOR OPENER AND THE GARAGE DOOR OPENED AS I PULLED INTO MY DRIVEWAY. I STOPPED THE CAR, A 2019 MAZDA CX-5, IN THE DRIVEWAY, PLACED IT IN PARK, GOT OUT OF MY VEHICLE AND ENTERED THE GARAGE. WHILE IN THE GARAGE FOR APPROXIMATELY 2-3 MINUTES, I TURNED AROUND TO SEE MY 2019 MAZDA CX-5 ACCELERATING TOWARD ME. THE CAR ROLLED UNTIL IT HIT THE WASHING MACHINE AND DRYER. I MANAGED TO AVOID GETTING PINNED BUT NOT BEFORE THE CAR RAN OVER MY FOOT. I MANAGED TO SQUEEZE PAST AND ENTER THE VEHICLE PLACING MY FOOT ON THE BRAKE AND PUTTING THE CAR BACK IN PARK.

WHILE DRIVING ON THE HIGHWAY WITH VERY LIGHT SNOW FALLING AND LESS THAN AN INCH OF WET ON THE ROAD, THE "FRONT RADAR BLOCKED" MESSAGE APPEARED! UPON LATER RESEARCH INTO THE MAZDA OWNER'S MANUAL IT INDICATES THE FOLLOWING SYSTEMS WERE NOT FUNCTIONING: MAZDA RADAR CRUISE CONTROL (MRCC) MAZDA RADAR CRUISE CONTROL WITH STOP & GO FUNCTION (MRCC WITH STOP & GO FUNCTION) DISTANCE RECOGNITION SUPPORT SYSTEM (DRSS) SMART BRAKE SUPPORT (SBS) APPARENTLY THE LOCATION OF THE FRONT RADAR IS BEHIND THE EMBLEM IN THE CENTER OF THE GRILL. MAZDA RECOMMENDS THAT THE OWNER CLEAN OFF THE EMBLEM OF ANY DIRT OR SNOW TO CORRECT THIS PROBLEM. DRIVING ON THE HIGHWAY IT IS NOT PRACTICAL TO PULL OVER AND CLEAN OFF THE EMBLEM WHEN IT WILL HAPPEN AGAIN IN THESE CONDITIONS. THIS IS A SERIOUS DESIGN FLAW THAT CAN LEAD TO ACCIDENTS. THE FRONT RADAR SHOULD BE RELOCATED IN A LOCATION NOT SUBJECT TO ROAD SPLATTER. IT COULD BE LOCATED WITH THE OTHER SENSORS BEHIND THE MIRROR IN THE MIDDLE TOP OF THE WINDSHIELD.

TRAFFIC WAS HEAVY ON THE PARKWAY THAT DAY SO THERE WAS A LOT OF STOPPING AND GOING. APPLYING THE BRAKES, THE CAR STARTED TO SLOW DOWN BUT SUDDENLY THERE WAS A JERK AND THE CAR ACCELERATE WHILE THE BRAKES WERE STILL BEING APPLIED. THERE WAS A FRONTAL COLLISION WHICH INDICATES THAT THE SMART BRAKES SYSTEM WAS ALSO NOT WORKING. THE WARNING 'BRAKE SYSTEM MALFUNCTION' APPEARED ON MY DASHBOARD AFTER THE ACCIDENT. MY INSURANCE COMPANY SENT A WRITTEN REQUEST FOR THE EDR TEST AND HAVE AGREED TO PAY THE FEE WITH THE EXPECTATION OF BEING PROVIDED WITH A QUOTE OF THE COST AND THE END RESULTS. MAZDA HAS NOT APPROVED THE REQUEST AND IT HAS BEEN OVER 3 WEEKS. ASKED TO SPEAK TO A SUPERVISOR AND DID NOT GET A RESPONSE.

SIGNIFICANT SAFETY ISSUE--THE ENTIRE MIDDLE SCREEN GOES BLANK, ALL ACCESS TO APPLE CAR PLAY STOPS, INCLUDING NAVIGATION, PHONE, TEXT, ETC. THE PHONE GOES BLANK. MUST PULL OVER AND THE HEAD UNIT WILL RESTART.TWICE AT DEALER FOR SAME ISSUES. THEY HAVE REPLACED PARTS, BUT STILL SAME PROBLEM.

I HAVE OWNED MY CAR FOR ONLY TWO MONTHS AND THE PAINT IS ALREADY CHIPPING. I HAVE NEVER OWNED A CAR WHERE THIS HAPPENED AFTER OWNING IT FOR SUCH A SHORT TIME. I USE THIS CAR FOR COMMUTING TO WORK ON THE HIGHWAY.

SIGNIFICANT SAFETY ISSUE--THE ENTIRE DASH AND MIDDLE SCREEN GOES BLACK, ALL MUSIC STOPS PLAYING, THE APPLE CARE PLAY DOESN'T WORK, ATTACHED IPHONE SOMETIMES GOES BLANK. MUST PULL OVER AND RESTART THE VEHICLE. PREVIOUSLY AT MAZDA OF OREM (UTAH) FOR RECALL AND THIS SAME ISSUE. RETURNED TODAY--9/1 8/19, DEALER NO IDEA WHY SCREENS SHUTTING OFF. HAPPENS WITHOUT NOTICE OF PROVOCATION. SIGNIFICANT SAFETY ISSUE,

ALL LIGHTS AND GAUGES TURN OFF AND DISABLE, INCLUDING: APPLE CAR PLAY, NAVIGATION, AUDIO, AIR CONDITIONING, BLUETOOTH, SENSORS, AND ALL GAGES IN THE DASH--

I HAD A FLAT TIRE ON THE FRONT LEFT CORNER OF THE VEHICLE WHILE DRIVING ON A HIGH SPEED HIGHWAY. IN MY EFFORT (AND THAT OF A WISCONSIN STATE TROOPER) TO INSTALL THE TEMPORARY SPARE TIRE I (WE) DISCOVERED IT WOULD NOT FIT ON THE CAR. IT SEEMED TO BE THE WRONG TYPE FOR MY VEHICLE. I HAD IT TOWED TO A NEARBY DEALERSHIP AND THEY TOO COULD NOT UNDERSTAND WHY THE SPARE WOULD NOT FIT. THE MECHANICS BEST GUESS IS THAT THE BRAKE CALIPER IS TO BIG FOR THE SPARE PREVENTING IT FROM BEING INSTALLED. SO THEY MOVED THE LEFT REAR WHEEL TO THE FRONT AND INSTALLED THE SPARE ON THE REAR CORNER. NOW LET'S BE CLEAR, I KNOW AND THE DEALERSHIP KNOWS THAT PUTTING THE SPARE ON THE REAR AXLE IS THE SAFEST WAY TO TRAVEL UNTIL A REPLACEMENT TIRE IS OBTAINED. BUT, WHEN YOU ARE STUCK ON A PATCH OF ASPHALT BETWEEN AN EXIT RAMP AND THE MAIN THOROUGHFARE WITH CARS FLYING BY YOU ON BOTH SIDES, AS I WAS, YOU JUST WANT TO GET THE HELL OUT OF THERE AND NOT TAKE ANY MORE TIME THAN NECESSARY LIKE ROTATING TIRES ON ONE SIDE OF THE CAR. I CONTACTED MAZDA ABOUT WHAT HAPPENED AND THEIR ANSWER WAS ONLY PUT THE SPARE ON THE REAR AXLE CITING AN EXCERPT FROM THE OWNER'S MANUAL. THAT STATEMENT IN THE MANUAL ONLY TELLS YOU IT COULD BE UNSAFE TO PUT THE SPARE ON THE FRONT BUT NOTHING TELLS YOU IT WON'T EVEN FIT. BECAUSE OF THIS LITTLE "DESIGN FLAW" I WAS FORCED INTO A PROLONGED DANGEROUS SITUATION. QUITE SIMPLY I SHOULD BE PROVIDED A SPARE THAT WILL FIT EVERY AXLE SO I CAN GET OUT OF HARMS WAY AS SOON AS POSSIBLE.

CAR ACCELERATES BY IT SELF FROM STANDING STOP.PULLING OUT OF PARKING STALL SHIFTING TO DRIVE CAR ACCELERATES TILL I PRESS BRAKE TWICE. THEN AFTER SLOWLY DRIVING OVER SPEED BUMP CAR ACCELERATED UP TO 25 TO 30 MPH TILL I PRESSED BRAKE TWICE . CAR NEW HAS 1800 MILES
