JM3KFBBM8P02592602023 MAZDA CX-5Select Package

My 2023 Mazda CX-5 (48,000 miles) is experiencing a loud mechanical whirring/grinding from the driver-side headlight assembly, a documented manufacturing defect involving foreign matter contamination of the internal LED cooling fan bearings (TSB 09-029/25). Despite the manufacturer acknowledging this factory-installed defect, Mazda has refused to proactively remedy the issue because the vehicle is nominally past its 36,000-mile bumper-to-bumper period. I have been explicitly advised by service personnel to continue operating the vehicle until the headlight unit 'entirely fails' before further assistance may be considered. This 'fail-first' directive is a reckless disregard for public safety; the internal cooling fan exists specifically to prevent the high-intensity LED from overheating. A failure of this fan leads directly to the sudden burnout of the main headlamp while the vehicle is in motion. Mazda is essentially requiring me to drive a vehicle with a known, ticking-clock lighting defect and wait for a total loss of visibility at night before they will address a part that was contaminated during their own production process. This is a critical safety hazard that places myself and other drivers at risk of a collision due to sudden headlamp failure.

Airbags failed to deploy in a collision where the front end of the vehicle was crushed, and a driver wearing a seat belt hit the steering wheel with enough force to fracture their sternum and cause two cervical fractures as well.

I am reporting a safety defect in my 2023 Mazda CX-5 involving the right headlight assembly. The internal LED cooling fan has failed, causing loud noise and excessive vibration. This is a confirmed manufacturing defect (documented in Mazda Service Alert SA-013-23). Safety Risk: The cooling fan is essential to prevent the LED from overheating. A failure of this component can cause the headlight to dim or shut off completely without warning while driving at night, creating a severe visibility hazard and increasing the risk of a crash. Repair Details: An authorized Mazda dealer confirmed the internal failure and verified no external damage. Despite being a 2023 vehicle and a known safety issue, Mazda North American Operations has refused to cover the repair.

Just out of warranty passenger headlight is making a humming noise. Many other owners are having same malfunctions. Cost to replace at dealership is around $2,000.00. LED headlight has a cooling fan that is failing. Many have been replaced under warranty. Mine started just outside of the warranty mileage. It’s a known issue that should have a recall issued.

Adaptive headlight motor does not work. It makes a huge noise. Unfortunately it is not under warranty but Mazda dealerships have informed me that this is a known issue. This is a concern because the headlight does not function properly and does not work. The issue is a motor that fails, however you cannot just replace the motor. The entire headlight assembly needs to be replaced and is over 2,000. I strongly believe Mazda should be looked into and a special recall should be issued due to this. There should not be. $2 part that fails continuously causing a $2,000 repair.

What component or system failed or malfunctioned, and is it available for inspection upon request? - Smart Brake Support (SBS) & Forward Obstruction Warning system malfunctioned. Front radar sensor malfunctioned. Parking brake malfunctioned. I-activesense system malfunctioned. Emergency lane keep disabled. Dynamic stability control malfunctioned. Traction control system not operating correctly. Anti-lock brake system (ABS) malfunctioned. Brake system not responding. How was your safety or the safety of others put at risk? In total 10 malfunctions led to brake not responding and could not stop the car and resulted into a car accident. 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? POLICE report from car accident states brake malfunction. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Car was totally fine until all 10 error messages appeared on Jan.17th 2026 12:42-12:43PM and immediately the brake system did not respond and resulted in the car accident. **important** Police report documented that the officer on scene is a witness of the car dashboard shows “brake malfunction”

Autobraking activates randomly. Mazda scans codes and returns the vehicle. They have refused to service or disable the system. NHTSA laws are dangerous and this tech is not ready for road use. Avoid Mazda at all costs!

Cracked cylinder head probably caused by cylinder deactivation causing catastrophic oil loss on the highway. Upon researching this, I see that it is a known issue with Mazda. My car is now in the shop awaiting repairs. It only has about 35,000 miles on it. This is obviously a known defect and is simply not acceptable.

The battery died, the car wouldn't start one night. The battery which is the original that came with the car is only about 2 years old. I googled the code from the code reader, it said some mazda cx-5 have a starting problem but then I checked the recall website and there was none.

LKA does not work & mazda seems to ignore its many complaints

Loud fan noise coming from the passenger side headlight. Noise continues when car has been turned off and stops when the light shuts off. Dealer said that replacement of the passenger headlamp assembly needed but would charge because it was not longer under warrant due to mileage. No warning lamps, messages nor other items appeared. The symptoms began around 40,000 miles.

Humming or moaning noise from the passenger side headlamp. Inspected by dealer mechanic and mentioned the TSB 09-015-23B bulletin. Dealership replaced headlamp covered under warranty.

After driving a few mile, the following two warnings come up * Smart Brake System Malfunction * Forward Radar Sensor System malfunction. If I turn off the car and then restart, the warnings go away. However, it comes back if I drive for a while again. I have visited dealership a few times for the same issue, they replaced the wheel bearing and brake switch. The warning disappeared for days and came back.

The adaptive headlight system and motor in 2023 Mazda CX-5 has defect and it makes buzzing noise and vibration. It was recognized by Mazda and its known defect. They should replace the defective headlight system even after the warranty period since this is not normal wear and tear part.

The driver-side power door mirror on my 2023 Mazda CX-5 vibrates excessively at highway speeds above 75 mph, especially on windy days. The vibration is so severe that it causes a blurred and distorted view, making it difficult to clearly see vehicles in adjacent lanes. This poses a significant safety risk, as it impairs my ability to make safe lane changes and monitor surrounding traffic. I brought the issue to the attention of my Mazda dealership during a scheduled service appointment, but they dismissed it as "normal" and quoted approximately $700 to replace the mirror - despite the fact that this appears to be a known issue with Mazda vehicles. Numerous owners of recent Mazda models have reported similar problems online, yet Mazda has not issued a Technical Service Bulletin (TSB) for the 2023 CX-5. I am attaching a previous TSB (09-002/13) that Mazda released for earlier CX-5 models (2013–2014), which addressed the same mirror vibration issue through structural reinforcement and mirror replacement. This suggests the problem may still persist in newer models. The mirror is available for inspection upon request. No warning lights or messages were displayed, and the issue began shortly after I started driving the vehicle on highways.

Fuel system failure. The vehicle just dies and does not restart, this is a safety issue due to it happening when you are driving on the highway and unable to get out of the way of traffic.

The vehicle turned the ac off and started blowing straight hot air into the vehicle after sitting in idle for less than 5 minutes. Which resulted in my dog having a seizure and passing away. There was not a notification on the app or any type of warning for this to happen.

The car has a lot of vibration when driving 60mph and above. Have had this issue looked at more than 5 times and they had my card for 1 month at the dealership trying to find the issue. This started back in February of 2024 and I have purchased 4 sets of tires and nothing makes the vibrations of the seat, steering wheel go away. Originally it wasn’t vibrating while driving back in February of 2025 only when braking to which I said to them I think it’s the rotors that have an issue. They never check the rotors and said it was my tires that were cupped. I put new tires on the car and still the same issue and went back to the dealership in April of 2024 and let them know it think it’s the rotors. In fact it was the rotors they were warped and they balanced the tires again. The dealership recommended resurfacing the rotors to which I had done. A Couple of months later the vibration while driving started. Bought another set of tires had then installed, balanced and aligned and still vibration. I thought maybe it’s the brand so I bought another set of tires to which the problem is still there. Now besides the vibration while driving I have vibrations while braking again after the dealership put in new rotors back in Nov. 2024. When to the dealership on 06.26.25 let them know the vibration while braking is happening again and I think it’s the rotors. They check them and rotors are warped again about only 6.5 months.The service manager said she will resurface them for me for no charge but then the service advisor said if they do that that the resurfacing is going to make me have to change the brake pads as I will end up in the red since my brake pads are in the yellow right now. I said then don’t resurface because I am not paying for the brake pads when that should’ve been done the first time the rotors were warped. I feel like I risk my life everyday driving this car to work 34miles one way.

Vehicle is a 2023 Mazda CX-5 Signature Turbo model that had a leaking hydraulic tensioner for the serpentine belt at 15,759 miles. Mazda technician cleaned the hydraulic tensioner, and less than 500 miles later the leak returned. This is common enough in the community to expand TSB’s on this part.

When driving the vehicle, my car exhibits a rocking / shake when going from brake to gas at speeds below 20 mph. I was told by the dealership that it is normal operation, but when driving two other CX5’s, the behavior did not exhibit. I do not know what to do. I have also brought it to 2 independent mechanics and they told me the engine mounts needed to be replaced. I did the service at 36,000 miles and it did not get rid of the problem. It seems to be a defect of the car, which I’ve been living with since 2023. The issue has been ongoing.

Summary of Events: Purchase Date: 05/27/2023 Coolant Warning: In January 2025, I received a coolant temperature warning (code P0126) indicating insufficient coolant temperature. Repairs: I brought the vehicle in for repairs on 02/15/2025 for thermostat and related parts. The repairs were completed by 02/17/2025. New Warning: On 03/18/2025, I received a high coolant temperature warning. Upon inspection, coolant was nearly empty, and I found coolant contamination in the engine bay. Notification to Dealership: I emailed Hennessy Mazda on 03/19/2025, but after no response, I filed a claim with Mazda headquarters on 03/20/2025. Only after that, they called me and instructed me to bring the vehicle in. They claimed that after replacing the faulty parts and cleaning the engine bay, the car was ready for pickup. (While they assert that all actions were completed on 03/22, Based on the fact that the car door was opened approximately five times in April, it can be inferred that the necessary actions were likely completed in early April.) Concerns: Coolant Leak: The coolant leak persisted for nearly a month, likely causing damage to internal components due to engine overheating. Electronic Contamination: The leaked coolant likely contaminated sensitive electronic systems, wiring, and connectors, potentially leading to long-term failures due to the conductive and corrosive properties of modern coolants like Mazda FL22. Long-Term Risks: Hidden corrosion inside connectors and wiring. Potential for electrical failure, sensor malfunctions, and further degradation over time. Hennessy Mazda is currently addressing only the visible issues and claiming the car is now functioning properly, while attempting to shift the long-term and hidden risks onto me. I am requesting a vehicle replacement or compensation due to the safety and long-term reliability risks posed by the unresolved coolant leak and contamination.

Extremely heavy steering causing excessive driver fatigue making it difficult to maintain control of the vehicle at highway speeds (up to 70mph). Dealers unable to reproduce, likely due to it being cold outside when I had time to go. The hotter and dryer the roads gets, the better grip the tires have and the worse the heavy steering gets. It is significantly heavier than my old car at higher speeds and that car has no power steering. My arms are very sore after 30min - 1 hour. Mazda refuses to admit this is a significant safety issue. It gets worse when the LKAS activates at least once (too heavy I am veering around in my lane)

I motor fan is constantly on when driving. It is 32F to 40F here in Hampton Roads. There is no reason the fan should be on. I have video of the fan running at 29 degrees F. I reported it to my local mazda 3 times. A person I know in another area reported the same problem and her local mazda dealer fixed it.

See attached document for complaint.

Small amount of weight such as keys or phone is triggering the Occupant sensor in the front passenger seat. This issue just started and I am finding a lot of complaints regarding this.

Engine light came on. Immediately brought to dealer. Always serviced at dealership. One previous occurance of illuminated light reading major engine malfunction. Pulled car to side of road, called dealership who advised turn off and back on. Didn't tell me about ALL the problems that Mazda was aware of. Now I'm told my new car with 22k miles has a blown engine. No notification from Mazda about a known problem. Asked when buying the car if there were any major problems with this car. Mazda apparently lies.

The contact owns a 2023 Mazda CX-5. The contact stated that while the temperature was 45 degrees or lower, the vehicle failed to start properly, and the engine failed to warm up properly. The coolant light was illuminated, and the engine temperature gauge failed to rise above COLD. The vehicle occasionally failed to start or while started and driving at various speeds, the vehicle stalled while and engine temperature failed to reach the normal operating temperature. The check engine light was illuminated. The contact would shift to SPORT Mode to prevent the cylinder activation from occurring and causing the vehicle to stall. The contact stated that the failure persisted, and the vehicle was hesitating while driving in temperatures of 50 degrees or less. Additionally, the key fob intermittently failed to unlock the vehicle. The contact stated that the vehicle failed to start and had to be towed. The contact stated that during the recent failure, the battery was disconnected, and the vehicle was towed to the dealer to be diagnosed. The contact stated that the key fob battery had been replaced 6 times; however, the failure persisted. The vehicle had not been diagnosed or repaired for the engine failure. The contact called another dealer, J. Allen Mazda (15150 Airport Rd, Gulfport, MS 39503); however, only an appointment to inspect the vehicle was made but the vehicle was not yet inspected. The manufacturer was made aware of the failure and a case was filed. The manufacturer referred the contact to the NHTSA Hotline to report the failure. The failure mileage was 4,000.

The Low Oil Warning Light comes on between oil changes. I think this is the 3-4th time. I will have to add 1 quart of oil to the car after 3000-4000 miles. I only have about 33,000 miles on this vehichle and do the oil changes myself. I checked for leaks at the oil filter and oil drain plug. No indication of oil leaking or I would see it on the floor of my garage. What component or system failed or malfunctioned, and is it available for inspection upon request? Engine using excessive amounts of oil. It could be available for inspection How was your safety or the safety of others put at risk? Has the problem been reproduced or confirmed by a dealer or independent service center? I plan to take it into the dealer for next oil change and report it. 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? The Low Oil warning comes on

The vehicle continues to have safety features malfunctions with its sensors. The forward facing camera sensor and the Blind Spot Monitoring Sensor continues to malfunctions when driving in clear visibility with light to heavy traffic at random times during a day. These features assist the driver to maintain a safe distance from other vehicles while driving. My vehicle has almost crashed several times due to the failures of the features such as the stop and go traffic and forward facing crash detection not working properly.

Headlight of the motor keeps rumbling in about 25000 miles of usage. Expense of fixing such a motor is estimated between 2500-2800$. Further, it is unknown how safe it would be for someone to keep driving such a car with a rumbling motor if they dont fix it. This sound and vibration of the motor can be felt even in a standing car when lights are on.

Blind spot sensors blocked error messages. This will happen at least a few times a year. Usually on long freeway drives, using cruise control, at night, and when cooler out (less than 60f). Restarting the vehicle makes the error codes go away and the system functions normally afterwards. Seems like either a software glitch or the system detects a guard rail for a while and gets confused and throws a Error message. This shouldn't be happening on a newer vehicle.

Was driving up [XXX] when simultaneously my dash board lit up with errors and malfunctions, my interior lights started flickering and my steering wheel and brakes locked. Unable to control the vehicle I gripped the wheel for dear life praying as it veered left. The 2023 CX 5 with only 18K struck the guard rail and went black on the inside and out. Only then was I able to counter the ricochet of the impact by redirecting the vehicle back on the grass to avoid getting smacked by 2 tractor trailers. SMH, I really almost died and now have to fight with my insurance to prove to them this is a real issue with these vehicle malfunctioning. I hope this helps someone and possibly save a life(s) - toyota_would_never, Greensboro, US INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When the vehicle light position is on Off at night the daytime running lights on the front of the vehicle come on which appear to be the same as the normal headlights, but the back lights are completely out. The brake lights work, but the back tail lights and licence plate light are out. The car's light switch is on the turn signal arm and can be moved inadvertently when using the turn signal. At this point you assume you have all around vehicle lights because the front headlights are on which are really the Day TIme Running Lights (DTRL). The DTRL are as bright as the normal headlights at night. This gives you the false impression that all of the outside vehicle lights are on. When this happens you are driving with no back vehicle lights which is a major saftey issue.

The driver's side mirror tends to vibrate or shake more than the passenger side mirror, especially at speeds above 50-60 mph or in windy conditions. It has been a common complaint among Mazda owners for quite a while, and it seems to be a design flaw that Mazda has not yet addressed with a permanent solution.

I love this car, but it has a bad habit, the vehicle accelerates on its own. If you take your foot off the gas, the car will intermittently lurch, almost jump forward. I’ve learned to deal with this by simply keeping a strong push on the break, but it is definitely is an issue. Another issue I’m having is the back lift gate. I’ve been told that the sensors are on each side of the gate and perhaps when drying the vehicle, I touch them they run along each side of the liftgate fully visible. I have 17,000 miles on my car right now and when the lift gate opens closes it stops halfway and it beeps. I then have to push it down to close. I took it to the dealer and they say it will cost me if they have to check the sensors. This is extremely annoying to have an automatic lift gate, and I have to push it down myself.

The contact owns a 2023 Mazda CX-5. The contact stated while the vehicle was parked, she entered the vehicle and noticed that the sunroof glass had exploded. The contact stated that she inspected the vehicle but could not determine the cause of the failure. The contact stated that the shade guard was closed at the time of the failure. The vehicle was taken to the dealer, where the contact was informed that the vehicle could not be serviced because a rock had probably struck the sunroof. The vehicle was not repaired. The manufacturer was notified of the failure, but no assistance was provided. The contact was awaiting an email from the manufacturer. The failure mileage was approximately 16,127.

Slowly and cautiously entered parking lot of a small strip mall. Proceeded to a parking space located in between two parked vehicles.Maneuvering into parking space I removed foot from gas pedal toward the break pedal; before foot made contact with break pedal the vehicle accelerated on its own surging over the cement parking bumper, over bushes, through the grass, down the curb and into the street. I jammed on the breaks. Lifting foot from break pedal I did not touch the gas pedal in fear the surge might happened again. Instead I allowed the vehicle to coast as I guided vehicle to the curb. In all the commotion, while trying to control vehicle safely I noticed the dashboard transmission indicator lights flash from park to drive to neutral. Safety issues for me and family at risk because we had no control over the acceleration of the vehicle.

I purchased a brand new 2023 Mazda Cx-5 on December 2022 from Daytona Mazda. The car has been great up until 34,310 miles when I noticed vibration in the steering wheel. I take the car to Sport Mazda North in Longwood Fl. They checked the brakes and rotors and tires. My brakes and rotors are fine. They stated my tires have cupping. They suggested a wheel balance to slow down the cupping process and they suggested and alignment as well. But that I would need to replace the tires if I wanted that cupping to be gone. I buy new tires and have them installed by Pep Boys because I was tired it the vibration. I have them check the alignment while I was there and the alignment came out great with all the numbers in the green. The tires still had 7/32nd left on the tires so that’s about 70% of tread left. The dealership downer warranty the tires and Yokohama won’t warranty them. They stated i needed to send the tires back. I let the rep know that ok so you wanted me to risk my safety to send those tires back to you to examine them. I let the rep know that I don’t have those tires as I had new tires put on on [XXX]. I am trying to get compensated for the new tires I had to buy because of a premature issue with the OEM tires.

While I was driving I heard an extremely loud noise (like fireworks). I slightly opened the sun roof cover and saw shards of glass. I pulled over to inspect further and realized that my sun roof glass had exploded! I saw no signs of anything (particularly rocks) that may have caused it. I called the dealer, and they had me bring it in. They have ordered a new sunroof, and gave me a loaner car. Luckily I did not have the inside cover open, or the glass would have shattered all over the inside of my car.

New 2023 Mazda CX5. We have experienced 2 Unintended Sudden Acceleration episodes. The most recent one was while backing down our driveway, the car suddenly accelerated when the brake was applied causing considerable damage to the car and house. Our front porch camera caught the entire episode showing that the brake lights were in fact on. Mazda needs to take responsibility and recall these vehicles to find out what is going on, as there are numerous other similar complaints for this car on this site and others.

I bought a new Premium Plus CX-5 in April of this year. Since I bought the car, occasionally I hear a sharp click or snap from the dashboard, particularly when it's warm outside and I have the AC on. I have video footage of the sound multiple times, but Mazda says they cannot replicate it. It sounds like a rock hitting the windshield type sound, but it's electronic and inside the car. Multiple Mazda dealerships in So Cal confirmed the noise. It is because the vents are chrome, aka plastic wrapped in thin metal. When the car cools, these will snap but not break / do any damage. This has been confirmed by at least 5 others on the internet. Please see this thread: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The sunroof spontaneously exploded outward while my wife was driving on the interstate. She was not near other vehicles or under an overpass for flying debris. We have had the vehicle for only 9 months and she works from home so it is kept in a garage for the majority of its life. It has not encountered any hail damage either. The sun shade was closed thankfully so my wife was fine but the anxiety it has caused her is immeasurable. This is a common occurrence as can be seen by any Google search indicating many people experiencing this issue. Most auto makers are not accepting responsibility for defects in manufacturing. The NHTSA has a duty to keep people safe and hold auto makers accountable for problems they are manufacturing. Exploding sunroofs are not safe and it is a major problem in the industry. There are countless testimonials and legal action being taken about this issue.

At 2:00 on a clear afternoon I was slowly coasting into a right hand turn into a parking space, and lightly tapping the brake to finalize the stop, when the car accelerated HARD forward over a curb and a sidewalk into the brick wall of a building. Airbag was deployed. My injuries were a nasty wrist contusion and bloody gashes where the airbag "door" deployed and I also had complete seatbelt brusing on my throat, chest and across my abdomen. This after traveling a mere 7-8 feet. At the time I was very shaken up and incredulous that such a thing could have happened logically, and conceded that perhaps I had made a mistake somehow. As I settled down later I became dubious, especially when I got behind the wheel of my rental car and 100% when I sat in my actual car at the wrecking yard. I am crystal clear I was depressing just the brake. Even if I had accidentally hit the accelerator instead of the brake (I did not) it would not have accelerated to the degree that it did. I am now scared of my car and am just hoping it is declared totaled by my insurance so I don't have to drive it again - any car but that one.

Mazda CX-5 Premium Between May and September this year, the MyMazda app has alerted me two times that the oil level was low. I manually checked and it was indeed low. The first time I brought it to a Firestone service center to have it checked and they verified that the level was down considerably to the bottom dot on the stick. They said to bring it to the dealer. I brought it to the dealer and they said they could not find any leaks and to come back in 1000 miles. I did that and they only checked the dipstick to make sure the level was fine and sent me on my way. The same exact thing happened again a week ago and I topped off the oil then made an appointment. The dealer said that I should not have done that and now they could not verify for themselves that the oil was in fact low. They disregarded the message that the MyMazda app sent me and did not care that I documented and took photos of the dipstick. They had to see it for themselves. They said to come back 1000 miles and not add oil if it is low. I said to the representative at the dealer that I had seen mentions about high oil consumption online and they stated it was only turbo models. I bought my car October 2022 and it has had this oil issue twice in 20,000 miles. That is scary and unacceptable.

Brand new 2023 Mazda CX-5 with 150 miles on it experienced unintended acceleration while braking. Pulled into a parking spot with my foot on the brakes but the car didn't stop & even accelerated over a sidewalk and into a building. I experienced a bruise from the seatbelt. Airbags did not deploy. Someone could have been killed if they had been on the sidewalk. Car is currently at an auto body shop to fix the cosmetic damages, and once released, will have the car towed to our local Mazda dealership/service center to get the car inspected. In doing research on NHTSA's website, at least 4 vehicles (2-2023 Mazda CX-5s and 2-2023 Mazda CX-30s) have experienced this issue. Mazda needs to recall these vehicles and investigate.

The contact owns a 2023 Mazda CX-5. The contact stated that while the vehicle was parked, he observed a crack from the middle of the windshield to the bottom corner of the driver's side windshield. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure but was unable to assist with the repair. The failure mileage was 2,802.

Car’s (less than a month old)rear glass shattered when shut the driver side door. No prior damage or wild temperature fluctuations. Could have been dangerous if occurred while driving or someone sitting in back seat. Wondering if there’s a defect in glass, or install.

When applying the brakes car surges forward. If put in neutral engine races. Very difficult to bring to a stop with reduced braking. Multiple occurrences. Dealer states vehicle is operating within design perimeters.

I was driving my new 2023 Mazda CX5 with approximately 1,300 miles in the center lane of a divided highway of the suburbs just north of New York City. I was driving with all windows closed, A/C turned on and the weather was clear, hot and sunny. Without any warning there was a loud and abrupt explosion from within the vehicle. As I looked in my rear view mirror I saw glass blowing in the wind behind me. I suddenly detected wind blowing above my head and realized my sunroof had most likely been the glass I saw behind me. I kept the sunshade closed with one hand until I could safely pull over to look. I did not suspect any road debris to have caused the breaking of the glass and my inspection did not reveal any other damage or possible outside causes. This even appeared to have been spontaneous and without warning. I feel that this incident could have been a lot worse had the sunshade been open, most likely blowing little pieces of glass into my eyes while driving at highway speeds in a center lane. I also fear that this could have been a hazard to my children passengers if they were in the back seat at the time it happened. I notified my Mazda dealership at the earliest possible moment and they asked to inspect it. After inspection, a regional service manager advised that this type of incident has been heard of but only in southern warmer states and typically on hot sunny days when the air conditioning is on inside the vehicle. Apparently the temperature difference coupled with cabin pressure and any sort of defects in the glass can make the glass explode upward. Date/time of incident 6/11/23 @ 5pm est. Date of repair by dealership: 6/15/23

Brakes are very poor, car lurches forward at stop lights and you have to stomp the brake pedal to prevent running into the car in front of you.

The power liftgate on the 2023 Mazda CX-5 SUV closes with sufficient force that the vehicle owner's manual warns of possible serious injury or even death, and cautions the operator to be sure that people or objects are not in the way of closure. However, the actual design of the overall system permits accidental closure by way of the key fob even when the operator is out of sight of the vehicle. This effectively renders the warnings meaningless, and disregards the safety of people or objects that might be in the way. The vehicle electronics/computer system uses dual purpose switches in or on the vehicle to activate the liftgate; if closed, a press of the switch will unlock and open it, and if open, the same switch will close and lock it. The system also provides the same feature with an exposed, raised button on the key fob which can easily be accidentally pressed to activate closure. Who then assumes liability for the possible resulting tragedy? During my first month of ownership (April 2023), I have experienced the liftgate opening by accident at least twice and it obviously could have been both opened and closed numerous times by accident totally without my knowledge. In a similar fashion, I have experienced the susceptibility of the other fob switches to accidental activation; the car has been locked by accident as least once, and the horn accidentally activated at least three times when I have been inside the house while the car is out of sight in the garage and the key fob was in my pocket. I am obviously making the reasonable assumption that accidental pressure on the various fob switches is the cause for activation. The attached PDF document describes in more detail some of the hazards posed by the existing design, and possibly applies to other car makes and models

4 month old car and brakes are rusted and rotor is warped. The car is shaky and rear right side grinder. Mechanic said it was safe to drive and that it was a “user error” for being to hard on the brakes. They said they inspected the vehicle and could not determine the “brown liquid” was. They cleaned what I assume was rust and claimed it was safe to drive again. Two weeks and three drives later it is grinding again, smelling smoky, and shaking. I feel unsafe driving the car. There were no warnings or messages when the symptoms first appeared. The car is available for inspection upon request. Although it has not directly put anyone at risk yet, I believe it is a matter of time before myself or someone else gets injured.
