The left and/or right side sun visor does not stay in the fully retracted position and may lower slightly due to its own weight. The problem is attributed to a broken connection point where the sun visor attaches to the vehicle. Impaired visibility, particularly in bright sunlight.

The I-Activesense camera disables all the time while driving. It disabled cruise control, LKA and LKA warning as well as auto high beams. While driving at highway speeds, when the vehicle drifts slightly over the line it does not get corrected nor do I receive ANY warning. It's almost as if the system knows it's there but doesn't want to turn on. While I was driving one day, it was very windy and the wind blew my car into the other lane slightly and almost collided with a vehicle. If the system was working that would not have happened. The problem was addressed at the dealership and I was told it was "normal". I've watched many videos on this exact model and trim. It is supposed to put my vehicle back into the center of the lane if it drifts over the lines. I will also add that every time this happens, the weather is perfect and nothing is obstructing the camera. The warning lamps that come on are the sensors disabled, auto high beams, forward collision, and cruise control

On December 13, 2025, my vehicle (2021 Mazda CX-30) was serviced at a Valvoline Instant Oil Change location. During service, the technician stated he was checking tire pressure and asked whether 36 PSI was acceptable. I agreed. When I pulled out of the bay, the tire pressure warning light remained on and showed 29 PSI. I stopped immediately and informed the technician. He then stated he could not inflate the rear-left tire because he could not remove the valve stem cap due to corrosion. This was not disclosed before the vehicle was released. The technician told me I should drive the vehicle anyway and suggested I try removing the cap myself using pliers. No written warning or safety notice was provided. On December 16, 2025, while traveling on Interstate 81, I heard a pop/rattle and the vehicle became progressively louder. A warning displayed: “TPMS Malfunction. Have the vehicle inspected.” I continued driving until I could safely exit. The tire was shredded by the time I pulled over. The incident appears consistent with progressive deflation/underinflation leading to tire failure. The vehicle was released for highway operation despite the technician’s stated inability to service the tire at the valve stem.

Two issues A) my usb or display stop to work often I have reset to make it work again, look like loose electrical 2) many time it has also happened start key malfunction error I have jumped start, I have replaced battery same issue

The contact owns a 2021 Mazda CX-30. The contact stated that while driving at an undisclosed speed, the accelerator pedal was slightly depressed; however, the vehicle speed increased significantly independently. The contact stated that the failure occurred as the contact arrived at the contact's residence and was attempting to park the vehicle. The contact stated that the brake pedal was depressed; however the vehicle failed to stop, and the vehicle was uncontrollable. The contact stated that the vehicle crashed into the contact’s apartment building. The contact stated that the building siding and steps were damaged due to the failure. The contact was not injured; however the failure had caused serious anxiety issues for the contact. The vehicle was towed to a local tow yard. In addition, the contact stated that the vehicle was towed to the dealer two times prior to the failure because, when attempting to start the vehicle, the vehicle failed to start. The contact was informed that the vehicle's not starting was the result of a faulty battery, and the battery was replaced. In addition, the contact stated that the independent acceleration failure had occurred the day before the crash occurred; however the contact was planning to take the vehicle to the dealer the following day. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 47,000.

As reported by others, Engine Malfunction light came on. Car running rough. Mazda dealer says corroded wiring harness and $5k to replace. They bypass the conventional repair and splice it in. Within a hour of driving after pick up, same engine malfunction light and rough running returns. This time they said I need a new transmission. Electrical issues and faulty transmission are both dangerous. With as much posted online regarding the transmission, I would hope to find a recall. $10k in repairs for a barely 4 yr old car!

-Driver seatbelt retractor has failed. Will no longer retract and it is available for inspection. -Safety is compromised due to pretensioner will not function in the event of a collision. Seatbelt will not perform as designed. -I have not taken the vehicle into the dealer but will be doing so. -The seatbelt issue has not been inspected by anyone as of yet. I am filling this out in case there are other owners with similar issues. There are quite a few complaints about this issue in Mazda forums. -There are no dash lights on at all indicating an issue.

The contact owns a 2021 Mazda CX-30. The contact stated that while operating the vehicle, the interior rear mirror loosened and eventually fell from the roof of the vehicle. The cause of the failure was not yet determined, and the vehicle was not yet repaired. Additionally, while driving at an undisclosed speed, the message "Critical Brake System Malfunction" was displayed. The vehicle was taken to the local mechanic; however, the cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The failure mileage was 22,000.

The contact owned 2021 Mazda CX-30. The contact stated while attempting to park the vehicle in the parking garage at her workplace, the contact reversed and then straightened the steering wheel; however, after shifting to drive and attempting to drive 6-10 feet forward into the parking space, the vehicle unintendedly accelerated and crashed into a pillar before coming to a stop. The contact stated that the engine had revved up, and the vehicle made an abnormally loud sound before the vehicle unintendedly accelerated. The contact stated that the brake pedal was depressed but the vehicle failed to respond, and the vehicle failed to stop as needed. There was no warning light illuminated. The contact stated that the air bags deployed as intended; however, a warning light indicating an air bag malfunction illuminated afterwards. The contact stated that the front driver's side and knee air bags had deployed as designed. The contact sustained pain and bruises on the left side of the chest, on the upper part of the left breast, on the left leg, and on the right wrist and right arm. The vehicle automatically called 9-1-1 for Emergency Assistance, but the contact declined to receive medical assistance. The contact was able to walk away from the scene. No Police report was filed. The contact was unsure whether there was any property damage. The vehicle was towed from the scene and totaled by the Insurance Company. The contact stated that the failure had occurred once before while driving at approximately 60-65 MPH, and the vehicle unintendedly accelerated with an abnormal sound coming from the vehicle, but the contact was able to depress the brake pedal and regained control of the vehicle. The dealer and the manufacturer were not yet notified of the failure. The failure mileage was approximately 31,000.

Received a "LOW ENGINE OIL LEVEL” warning message before the regular oil change interval of 7,500. Light came on 11/20/24 after purchasing the vehicle from a Mazda dealership 8/10/24 (~3 months). Model and VIN were impacted by the Mazda Valve Stem Seal Settlement. This issue was not disclosed by the dealer.

Upon opening rear hatch, loud banging/knock developed that happened on every opening. Sounded as if it were damaging the body or latch. Did online research of problem and found through Mazda owners forum Mazda TSB #09-009/23. The TSB notes the rear latch has an "internal fault in the liftgate latch and/or loose bolts." Dealers are advised to confirm the issue and replace with new latch and bolts - "This repair will be covered under Mazda's New Vehicle Limited Warranty term." My vehicle had 71,500 miles at the time of the issue, just beyond the warranty limits. I took my vehicle to the local dealership (Whitten) along with the TSB where the problem was confirmed and I was requested to approve replacement. I argued that this should be considered a recall and covered by Mazda given the language of the TSB. The dealership advised that I would need to pay for the repair and could take up the issue directly with Mazda. Therefore, I paid $512 for the latch repair because I considered the problem a potential safety issue - either it would stop opening or would not close leaving the hatch open during driving. I contacted Mazda USA requesting reimbursement for the repair given their admission that the latch was "faulty." They refused saying my vehicle was beyond the warranty period and I had approved and paid for the repair. They added that I should contact them in the future if there is a question about coverage of broken parts. Given their admission that the part installed at the factory had a fault and that this fault could result in a safety issue such as a non-closing hatch, I request that this issue become a recall, or that the warranty period be extended for this specific issue. (I would also like to be reimbursed for the cost of repairing this manufacturer's problem.)

For 4-5 weeks the car often would not start. Jump the battery and it would start. Run fine 1-2 days then require another jump. At end required jump nearly every time it was to be used. Presently at Mazda dealer. They confirm the problem. They cannot find the cause. Car has been there two weeks. Waiting for assistance from manufacturer. I researched this on the internet. Visited many Mazda forums an 'do it yourself" forums. This seems to be a common problem. NO where have I read about a satisfactory solution. In fact, it sounds like there is none. Dealer's proposal so far has been to replace rear wiring harness at $7000. It sounds to me that there is a manufacturing problem. Who ever heard of a wiring harness go bad? I believe this to be a poor electronic sensor/device, or perhaps poor wiring. Either case it would be the manufacturers fault. And I believe that the manufacturer should repair it at their expense. I grew up in a garage and never heard of anything like this. The car approximately 21000 miles. All of them are easy highway miles with no abuse or offroad/dirt road use. Yesterday my wife heard about a Subaru that was doing the same thing. Maybe someone in Japan is manufacturing faulty parts. If so that is the manufacturers problem, not mine. So far the car has not stalled going down the highway but one drives it with an uneasy feeling. Stopping without warning on the roadway would be very dangerous. Also, one could get stranded in poor conditions or environment, and that makes this a safety issue. I have attached file regarding battery etc. test I performed. These test have been confirmed by the dealer.

The contact owns a 2021 Mazda CX-30. The contact stated while driving 65 MPH, the vehicle stalled. The messages "Engine Malfunction" and "Computer System Issues" were displayed. The contact was able to pull over to the side of the road. Another driver assisted the contact in jumpstarting the vehicle. The contact was able to drive to her friend's residence. The contact then drove to her residence the following day. The contact stated while starting the vehicle, the vehicle jerked and the failure recurred. An unknown dealer was notified of the failure and provided an estimate for a diagnostic test. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 30,590.

Battery would be completely drained overnight if the doors are not locked.

While I was driving on I-90, I lost control of the acceleration of my vehicle. The vehicle was towed and has been diagnosed with a failed transmission! The car would not accelerate or it would accelerate in bursts or rapidly slow down. I was able to pull over and the car failed to move at all after. My safety and others was put at risk as I lost the ability to control the speed of the vehicle on a road where the speed limit is 65mph in traffic around me. When the problem began no lights illuminated, until ~30 seconds in the yellow engine failure light illuminated and then the yellow transmission failure light illuminated. The car was brought to a dealership for inspection and they diagnosed it as a transmission failure. This is unacceptable for such a young vehicle (2021). It should be noted that the car manufacturer immediately approved the replacement the same day it was diagnosed (dealership said it usually takes 48 hours), but the part is back-ordered for months (probably because they know this is happening and trying to cover it up).

Vehicle makes a noise on the driver side headlight when light is on. Once headlight is off, noise is gone.

Seatback fold mechanism loose. Vehicle only has 23,000 miles and seat is starting to come loose.

Had to replace tie rods two times before 11,000 miles.

My oil changes were affected as well.

Car lunged forward when lightly stepping on the gas while making a turn onto a busy street. Then it later lagged in responding when I stepped on the gas. About 5 minutes later, the car dashboard lit up and said there was a transmission error. Mechanic's diagnosis found code P0756 for a shift solenoid B stuck off. The car is unsafe to drive.

Low engine oil light is on again, I had one at 4600 miles and keep happening every 5-6000 miles. I had 7!! oil changes on a car that is 2.5 years old and it is at 29000 miles. I am sitting at the dealership and they are telling me nothing is wrong and despite of the valve stem cap replacement available they are not willing to replace it. In addition I had my battery die and needed to be replaced at 23 months after purchasing a brand new car - due to a faulty system. This is getting extremely upsetting. And dealearships do not care.

The car has some .kind of Electric or electronic malfunction that drains the battery and kills it without giving you a warning. I have taking it to a Mazda Dealer to be fix 4 times and they don't seem to be able to fix it.The battery was replaced.twice one by me and the second time by the dealer in an attempt to solve the problem at some point. Unfortunately just yesterday it happened again it had to towed to the Mazda dealer again for the fifth time. I really hope a solution can be found.

On multiple occasions, low oil warning lamp illuminates and I have confirmed low oil level. Dealer is unable to confirm and refuses to address Mazda TSB because oil level is no longer low since I topped it up. The failure lies in the valve seal assembly. My safety and that of my passengers is affected because in the event of a low oil incident, my ability to safely drive the speed limit and/or accelerate quickly is compromised. Should a catastrophic failure occur, engine would lose all power. Date of most recent incident marked below.

Low engine oil on the turbo model. It happened several times. 16k miles.

I'm getting a critical engine error with the car saying I have low oil pressure. The dealership has looked and said that they can't fix it. They said I can drive it with the warning up

The contact owns a 2021 Mazda CX-30. The contact stated that while the contact's wife was driving at an undisclosed speed, several unknown warning lights illuminated. The contact stated that the vehicle decelerated to 20 MPH. The contact's wife drove the vehicle to a safe location and parked the vehicle. The vehicle was towed to an independent mechanic, but the mechanic was unable to duplicate the failure. The contact stated that the independent mechanic reset the codes and the vehicle operated as intended; however, the failure recurred. The vehicle was taken to the dealer and the contact was informed that the battery needed to be replaced. The battery was replaced but the failure reoccurred. The vehicle was taken back to the dealer where it was diagnosed with a failed MAP sensor. The contact was informed that the MAP sensor needed to be replaced. The vehicle remained with the dealer for nineteen days and the MAP sensor was replaced. The vehicle was repaired; however, the failure reoccurred. The vehicle was taken back to the dealer where it was diagnosed with needing a software update. The vehicle was at the dealer for another 34 days and the software update was completed and the PCM was replaced. The vehicle was repaired but the failure reoccurred. The contact stated that the failure had been persistent. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure but provided no assistance. The failure mileage was approximately 36,500.

Engine is burning an excessive amount of oil. After numerous times to the dealership Mazda has finally okay the "fix" to be done to the car. What this "fix" is I do not know.

The accident occurred on the afternoon of Tuesday, November 14, which I reported to Enterprise, City of Falls Church, on the morning of November 15. Additionally, I provided to Enterprise email links to the many reports about breaking problems about the CX30 2021, 2022, and 2023 MAZA models and the reasons for their recall for repair. Here are the details about what happened. As I was trying to put the car in reverse from a standing position, the car, instead, lurched forward at great speed headed toward the Sun Trust bank. I had to use super-human strength to the brake pedal on the car to force it into a standing position. The damage to the car is due to scrapping some bark off one of the trees that separates the Sun Trust Bank property from the CapitalOne bank property where my car was parked.

I have noticed the windshield is distorted and from reports all over the Internet that seems to be an issue with 20-22 mazda cx-30’s and I don’t think Mazda is going to replace it. It causes me to get fatigued, and a little dizzy at times during long distance driving.

Rear brakes became extremely worn very quickly. Had to replace in September of 2023 and purchased the car with 0 miles in February of 2022.

Rear brakes became extremely worn very quickly. Had to replace rear brakes in September of 2023. Purchased the car with 0 miles in February of 2022.

Low oil indicator came on after only1,800 miles since an oil change, I added a quart of oil and then the light came on again after only 1,000 miles. Asked the service department at the dealership and they said there was an issue with the oil and the turbo system and that it would be a three day repair. I was advised in the meantime to take a couple of extra quarts of oil if I was going to doing any traveling this summer.

Adaptive cruise control on at 70mph, speeding car pulls into my lane with no gap (completely cut me off), hard brake by computer, I did not tap the brake to take it off of cruise, car that had cut me off zigs into another lane while adaptive cruise control has car at about 40 mph due to hard brake. As car in front pulls out of the lane, adaptive cruise control guns the engine to 3500-4000 rpm since there was no obstruction in front of it anymore and it wanted to go back to the 70 mph preset. During this incident the Engine Malfunction light comes on, warning to get car serviced. Upon taking it in for service they found that the thermostat needed to be replaced? This seems unlikely. Car has only 15k miles on it. I have another model Mazda and the adaptive cruise control has gunned it in a similar manner, taking the car well past 3000 rpm. Mazda needs to reprogram.

Low engine oil level since I bought it in September 2021. I’ve had it at the dealer three times and they’ve said there are no codes on the car but they are on my Mazda app. They want me to drive it over a hour away with low oil to prove to them that the engine oil is low. I did this, shut the car off, the light went off and when the engine oil level was checked it read one quart low.

“Low engine oil level” light comes on periodically for last several hundred miles. Dipstick show oil level to be appropriate.

Vehicle burns oil at at much higher rate than scheduled oil changes allow.

The engine oil light came on several times on different days, saying that the engine oil level is low. But I had the car checked twice and there is nothing wrong the engine oil level.

I would like to report that I am not feeling safe driving my 2021 MAZDA CX-30 Premium anymore. My vehicle is affected by the MAZDA Technical Service Bulletin 01-003/23,. Subject: ENGINE OIL LEVEL WARNING LIGHT ON WITH DTC P250f:00 DUE TO LOW ENGINE OIL LEVEL This is a known issue by MAZDA! It results in an oil consumption increase due to damage of the valve seals on the exhaust side. The first time the Engine warning light with the message "Engine Oil Level Low" was displayed on May 20, 2023. the earliest appointment to get this issue diagnoised and repaired was on 06/30/2023 at the MAZDA dealer in Augusta, ME. They diagnosed the issue but were not able to repair it, since they don't have the required level of technician as outlined in TSB 01-003/23. I then had to reach out to another MAZDA dealer, Thompson Mazda in Waterville, ME. They ignored my complaint over the phone, not accepting that this issue was already corectly diagnosed by the other MAZDA dealer in Augusta, ME. I contacted MAZDA of North America Customer Relations but didn't get any support so far. They told me the earliest date to get the vehicle diagnoesed and possibly repaired would be end of September. I told them that this is unacceptable and I don't feel safe driving the vehicle with this known issue.

I was involved in a traffic accident on 6/29/23 involving myself and my [xx] year old son, both in the front seat. We were struck in the back by one vehicle, spun out of control, hit another vehicle on the passenger side where my son was sitting and spun out of control again. Driver side did not strike anything and side airbags deployed (both front seat and back seat), passenger side airbags never deployed. My son's safety was put at risk as the damage was extensive and the car was totaled. He suffered two fractures in his shoulder and a broken clavicle. The problem has not been confirmed by the dealer. The vehicle has been inspected by my insurance carrier, Progressive. There were no warning lights, and no lights confirming that the airbag was turned off while my son was sitting in the passenger side. “INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).”

The low engine oil warning light keeps coming on, and there’s appears to be no visible leak. I add about a quart each time this happens and it does fine for a while. The last time I took it to the dealership, I told them about it. They just said they didn’t see a leak and not to worry about it. Ultimately the issue is how will this impact the longevity of my engine?

After setting the adaptive cruise control, and overriding it with the accelerator pedal when approaching a vehicle in front of me to pass it, my vehicle briefly accelerated hard while switching lanes after clearing the vehicle in front of me. This happened even though I had taken my foot off the accelerator already. My current speed was also slightly higher than the set cruise speed. E.g. I set it to 75, I was driving 77 and it jumped up to 80 for a short while before settling back to 75. This acceleration happened right as I cleared the vehicle in front of me and I was in the other lane. You can feel the sudden acceleration. It is as if the radar noticed the vehicle wasn't in front of it any more so it accelerated disregarding the current speed or accelerator position.

On March 9, 2023 - car brakes failed at a red light and vehicle collided with an oncoming car coming from the adjacent direction. Vehicle proceeded not to brake for an additional 30 sec minum at which the brakes finally engaged. There was no braking alert - the smart braking system did not engage and there was Forward Collision warning. It is available for inspection upon request. My safety and the safety of oncoming passengers were at risk which could have been fatal Insurance representatives have not yet inspected. Absolutely no warning lots engaged.

Involved in an accident low speed on 3/17/23. Upon impact with other car passengers seat belt did not activate until passenger hit dash with her head and then it apparently engaged and threw passenger back with tremendous force injuring passenger. Upon inspection at the body shop they found the following code: U0452..invalid data received from restraints control Panel. History. They will be calling Madza for inspection. This needs to be inspected as soon as possible before someone gets killed.

I picked up my certified pre owned CX-30 just 2 days ago and noticed the windshield appears distorted or wavy which results in eye strain and headaches. This seems to occur in the left side of the windshield. It is difficult to focus for long periods of time. I asked another person to drive the car and they confirmed it nearly instantly. I recently learned this is a known issue with the vehicle.

The contact owned a 2021 Mazda CX-30. The contact stated that her husband was driving 60 mph on cruise control and while approaching a traffic light he depressed the brake pedal but failed to deactivate the cruise control and stop the vehicle. The contact stated no warning light was illuminated. The driver steered to the right and crashed into another vehicle. The contact stated all the air bags did deploy. The driver sustained leisure on his back and both legs due to the air bag deployment. The contact sustained leisure on her head, her nose, her left ribs, hips, and both legs due to the air bag deployment. The contact stated they both sought medical attention at a near hospital. The contact did not know in detail the injuries of the other individuals but did know both individuals sought medical attention. A police report was filed. The vehicle was not drivable. The insurance company deemed the vehicle a total loss. The vehicle was towed to an unknown location. A dealer was not contacted. The manufacturer had not been informed of the failure. The failure mileage was approximately 14,000.

Safety and Driver Support Systems partially disabled, camera malfunction drive safe and High Beam Control Disabled this 3 are on the speedometer. Took it to the local dealership and they don’t know what or how it happen. They worked on it today but can not find a way to fix it .

I purchased a Mazda CX-30 October 2021 - in April of 2022 the oil light came on mileage 4,672 and I decided to have just have the oil changed at Hello Mazda of San Diego. They said they wouldn't charge me for the oil only the service charge. And mentioned that something is wrong and will top the oil off at no charge in the future. Last month in November I took a short trip to Tucson AZ to visit family the oil light came on once again mileage 10,079 I brought the car into Jim Click Mazda Tucson and after several hours I got the car back. They had topped off the oil with no charge. I asked how low the oil was. The service man quickly said just a little low under a quart. I didn't want to argue with him- but I checked the oil stick, and it was below a quart and I know a light most likely won't come on without it being at least a quart low.

The sunroof exploded while driving. If the inner shield hadnt been up the glass would have fallen on 2 people and a dog. The explosion was so loud my left ear is hurting. Nothing dropped on the sunroof. It exploded upwards. We thought our car had been shot.

Using a quart of oil every 1,500 miles. Known oil consumption issue with the 2021 Mazda CX 30 turbo 2.5 engine

The contact owned a 2021 Mazda CX30. The contact stated while making a left turn, another vehicle struck the middle of her vehicle causing server damage. The contact stated that none of the frontal air bags were deployed. The contact suffered severe injuries and she sought medical attention. The vehicle was declared a total loss. A police report was filed. The manufacturer was not contacted. The failure mileage was 13,450.

The car's battery has failed two times. The second time is after the battery was replaced -- so the problem was with two different batteries. Both times, I had to call & wait for roadside assistance. Dangerous situation. Both times, the car required a jump-start then a full charge. The dealer denies a battery problem or electrical system problem. However, a Mazda Roadside Assistance service provided advised me on 12/3/2022 that the (second) battery was dead and that something in the electrical system is clearly draining the battery. The car is driven every day. *** Several times a week there is a dashboard notice of "low battery risk". *** This has been consistent, starting with the first week of owning the car. It appears that something(s) in the electrical system is draining the battery to the point of failure. The car is 18 months old with @ 16,500 miles driven. It is a 2021 Mazda CX-30 Turbo Premium Plus. It is available for inspection.

Was driving on interstate, during the afternoon, not close to any other traffic ahead. It was neither raining nor particularly windy. I heard a very loud “explosion” sound, like a gunshot. I pulled over and my sunroof is bowed OUTWARD a little, and missing a big section of glass. There is no rock or debris laying on the interior screen, and the sunroof is NOT concave like from an impact. It is clearly blown upward.

The Low Oil Level light/sensor came on before it was time to get an oil change (the recommended 4600 miles). This is super dangerous as it can cause major engine issues. I took it to the dealership and the dealership stated "they are having problems with these cars-they are burning too much oil so there is going to be a replacement valve once they have one made and you'll need to come back in to have it replaced -it will be a big job since it's part of the engine".

Purchased Mazda CX-30 Turbo car new March 31, 2021, in Jan 2022 low oil light came on with only 5,000 miles. Dealer noted it was 1 qt low. Just prior to reaching 10,000 miles the low oil light came on again. This car is burning oil with normal driving; primarily from rural area into town 15 min away or freeway driving. This creates an unsafe situation with parts and engine failure.

Low Engine Oil displayed on dashboard after only a couple thousand miles/four months from last oil change service. Known issue with this year/model for a year (https://static.nhtsa.gov/odi/tsbs/2021/MC-10203724-0001.pdf), but no recall or fix has been offered other than topping off or changing the oil. The dealer did top off the oil for free as the notice says.

Notable distortion in the windshield horizontally through driver and passenger areas. Dealership has been helpful in replacing the windshield three times thus far. The most recent windshield is clearer but still with notable distortion and is considered an aftermarket windshield. Mazda is aware of the issue and was told they are giving pushback on replacements. This issue is noted numerous times on multiple Mazda forums with no solution. From conversations with the dealership, Mazda is claiming this is normal especially close to the pillars due to vehicle design. This issue causes driver fatigue and distance perception problems while driving which is considered a road safety concern. Paperwork and vehicle are available for inspection upon request.

Continuous oil loss from engine. No leaks but oil level diminishes and warning lights come on monthly.

I am constantly receiving a “Low Battery Voltage Warning” for reasons as simple as leaving my door or trunk open for 10 minutes. I never leave my car in accessory mode to play music or anything that might drain the battery. It happens several times a month for no reason. I have not had it die on me yet, but I don’t know if it’s actually a low battery or software glitch.

Identified low oil level with 5,500 miles on the odemeter. No leak detected. The car has been babied; no accidents or undercarriage damage.

Purchased this car on Saturday August 13th from a dealer. Last weekend on the 20th the low engine level warning came on. We checked the oil and it was at the lowest dot on the dipstick. We added one quart of oil. This car isn't even due for an oil change it shouldn't be losing any oil.

Losing/burning oil with no leaking - less than 8,000 miles. Mazda has issued a service bulletin on the issue but offers no actual repair solution. Could be dangerous if engine seizes while in operation.

Low engine oil light came on after 3 months of driving. I know this is a common issue on the turbo model, yet there has not been a recall.

engine oil low light coming on within 3000 miles of oil change

Oil warning light came in at 5,500 miles. Dealer says they know the engine consumes oil.

Engine is consuming/burning oil. I have needed to add 1 qt of oil every 3-4k miles, since purchased new. Car now has 25,000 miles and I have added oil 6 times. Ive called the dealer(Classic Mazda in Mentor Ohio) and they insist this is normal and there is no issue with the engine. Yet, I read on the internet that this is a known problem.

The car has been reporting low engine oil numerous times between oil changes.

I have just about 8800 miles on my Mazda CX-30 Turbo after a year and 5 months. Suddenly had my low oil engine light come on. I pulled over and the oil is barely on the tip of the oil stick. My last oil change, which was also my first, was completed at 4937 miles from the Mazda dealership.

Excessive oil consumption. I bought this vehicle new from a Mazda dealership, with factory warranty. The check engine oil light came on at approximately 6800 miles, 3750 miles after the first oil change. An additional quart of oil was added. I brought it back to Mazda to confirm no oil leaks, which they confirmed. They were made aware of the Mazda service bulletin for excessive oil consumption, which they acknowledged, but indicated they will monitor as there is no solution from the factory.

The automatic braking engaged without warning and without cause. There was nothing directly in front of the car that was a possible collision threat. I suffered a neck injury as a result of the force in which the car stopped. Fortunately the driver behind me was able to stop. The car was taken to the original Mazda dealer and I was told this is a problem with my car but that they had no permanent fix, nor the ability to permanently shut off this system available until "corporate got back to them." They did not provide any paperwork and stated "we will call you when we have something." I now have a car I am scared to drive.

Yesterday I heard a very light ting sound. I did not think much of it. When I stopped I checked for any windshield damage, I could not locate any. After having the car parked for several hours, to my utter shock I had about a 1' long crack in my windshield. After looking for some time, I located the microscopic chip that caused the issue. I believe the windshield is defective! It is either too thin, too brittle, or both. Which could be a safety hazard.

low oil indicator keeps coming on at 3k miles and 8k miles. some times the oil is slightly low. The manual says to sop driving immediately, but that is not always possible.

My car is burning a quart of oil every 1500 miles. I have taken it to the dealer three times. They say that they know about the problem but don't have a fix. I am afraid that the engine could seize up during driving, causing a accident.

Driving home from work today I got a "low engine oil level" alert/warning. First time this has happened. I have approx. 15,500 miles on my vehicle and it was serviced on 3/22/22 (11,828 miles). That service included a full oil and filter change. I see it has been noted that there is an oil leak with this particular vehicle but Mazda has not been able to figure out what is causing it. Just wanted it to be reported

The windshield in my 2021 CX30 had a distorted view on the passenger side of vehicle. Took it in to dealership who confirmed that there was obvious distortion in the windshield. Windshield was replaced and the new windshield has the same issue. Mazda is now saying that it is "normal" to have some distortion on this particular model and they will not replace the windshield again.

Low engine oil light came on at 4600 miles. Brand new vehicle. Excessive consumption of oil known issue with this make/model

Low engine oil light came on at 8990 miles. Bought vehicle brand new. Has occurred before with this same vehicle. Excessive oil consumption is a known issue with this make/model

Randomly accelerated on its own; burns oil- low oil levels twice in 6 months; randomly says cruise control is available under 25 mph when car is traveling at highway speeds; the unlock and lock functions randomly fail; lift gate randomly opens; alarm system randomly goes off; TERRIBLE fuel economy (18-21 mpg)

Low engine oil pressure light came on forcing me to stop driving the vehicle. Upon investigation, engine oil level was a full quart low of oil, despite no leaks and only having 8000 miles.

I have the 2.5 liter turbocharged engine in my CX-30. It currently has approximately 18,000 miles after a little over a year of ownership. So far I have had to put in 3 quarts of oil in that time. The engine/low oil indicator comes on about every 4,000 miles. When I check the oil, it shows that it is down a quart. I have taken it in for regular service (oil and filter, tire rotation) twice now, and have brought this to the attention of the service advisor who tells me that this is normal for turbo engines. I disagree with this assessment. I will bring it up again later this week when it goes in for its third service. No new car should consume oil at the rate this one does. I have also observed blue smoke from the exhaust on start-up. I owned another turbo Mazda model a few years ago that did not do this. I have found what appears to be a technical service bulletin from Mazda regarding all turbocharged 2021 models built prior to September 2021. (TSB-01-012-21) My greatest concern is that this will only become worse and end up causing major damage to the engine and/or make the car unsafe to drive.

Low engine oil after 4630 miles!

The contact owns a 2021 Mazda CX-30. The contact stated that the low engine oil warning light was illuminated. The contact stated that the app used for alerting vehicle failure also notified the contact of the failure. The failure occurred twice. The dealer was contacted and informed her that it was a known issue however, there was no recall. The contact had not taken the vehicle to the dealer. The vehicle had not been diagnosed or repaired. The manufacturer was not made aware of the failure. The approximate failure mileage 3,100.

While driving, Low Engine Oil light illuminated. Vehicle has 9968 miles at time of incident and had one oil change at 5873 miles. So in the span of 4095 miles, engine had burned enough oil that none was showing on dipstick at time of incident. Vehicle was taken to dealership where it was confirmed that there were no leaks and the engine was consuming oil at a rapid rate. Mazda has issued a bulletin to dealerships concerning this issue, so the company is aware a problem exists with this engine. Had the oil level decreased to a low enough level, the engine could have feasibly failed, which could have resulted in a dangerous situation if it happened on the highway or in heavy traffic. Mazda currently has no fix and encourages that oil be added when necessary. Given the unpredictable frequency of the oil consumption, this does not feel like a safe solution, putting the onus entirely on the owner.

At about 3,605 miles, I received a low engine oil warning. The car is only 4 months old. When i took the car to the dealer, apparently there is a TSB that was issued in October 2021 about the problem. I bought the car in November was not advised of this issue. At this time, it appears at this time Mazda is unable to determine the root cause. It appears that I am to take the vehicle to the dealer every time I have this experience. I am worried about the potential impact and the lifespan of the engine.

Multiple warning messages came on including "Pus button start malfunction. Have the vehicle inspected." "In-vehicle network malfunction. Have the vehicle inspected." "Auto light system malfunction. Turn on/off lights manually." "Power steering malfunction. Have the vehicle inspected." "Driver attention alert disabled." Vehicle would not start after this and had to be towed to a Mazda dealership.

There is a warp in the windshield on the driver's side of the car that causes noticeable distortion. It causes eye pain and headaches. It also causes distortion and visibility issues when driving at night.

Low engine oil light displayed at 7,030 miles. No leaks detected. Engine consuming oil burning in combustion chamber. Possible engine damage or failure if oil was not quickly refilled.

The contact owns a 2021 Mazda CX-30. The contact stated that while at a stop sign, the vehicle was bouncing up and down. The contact mentioned that the failure recurred multiple times and only while the vehicle was stopped. The dealer was contacted but was unable to provide a diagnosis. The vehicle was not repaired. The manufacturer was not notified of the failure. In addition, while driving at approximately 8 mph, the brake assist warning light illuminated, and the brake assist applied independently while there was nothing in front of the vehicle. The approximate failure mileage was 3,500. As of November 5, 2021 the mileage was noted as 6,301 by Manchester Mazda. The vehicle would start bouncing up and down and moving forwards and backwards while stopped at a stop light and this occurred multiple times shortly after the purchase, within a month of purchase and randomly continued up to the point of the following issue. Consumer had shut off the brake assist every time she was driving there have been no more incidences. In addition, having the winter tires put on stopped the incident from recurring.

The contact leased a 2021 Mazda CX-30. The contact stated that the vehicle had failed to start up after multiple attempts with several unknown warning lights illuminated on the instrument panel. The contact stated that an unauthorized independent tow company towed the vehicle to a dealer two hours away from her home and that the vehicle was stolen from the dealer's lot. A police report was filed. The contact then stated that the vehicle was recovered and returned to the same dealer. The battery was replaced, and the vehicle was towed to an auto body shop to repair the damage to the vehicle. The manufacturer was notified of the failure but offered no assistance. The vehicle had yet to be repaired. The failure mileage was 2,100. The VIN was not available.

Manufacturing defect in the windshield glass: distorted/warped windshield glass causing waves/ripples. Result: impaired visibility when operating vehicle and rapid eye fatigue. Google search (forums) indicates that this is a well known issue on several Mazda models. The issue presumably existed at factory. I noticed upon purchase as CPO at 6k miles. Available for inspection if needed.

The brand new vehicle was sold to me on 2/23/21 with an open safety recall. This recall was finally addressed on 5/21/21. At no time did Mazda north American operations formally notifying me of the safety record. 1) how could this happen? 2) has this shortcoming been remedied? 3) Will I receive formal notifications of future safety recalls on a timely basis?

Sudden, enexpected emergency braking when there was no vehicle or any other obstruction in front of me. Luckily, the distance between me and the car behind me was great enough to prevent me from being rear ended.

AFTER TURNING LEFT AT A SIGNALED INTERSECTION ONTO A HIGHWAY THE AUTOMATIC BRAKING ENGAGED AND THE CAR SKIDDED TO A STOP IN THE MIDDLE OF THE LANE. LUCKILY NOBODY WAS BEHIND US. THERE WAS A CAR ABOUT 4 CAR LENGTHS AHEAD THAT WAS GOING THE SAME SPEED AND WAS NOT STOPPED. I PULLED OVER AND CHECKED THE FRONT SENSOR AND NOTICED A COUPLE BLACK FLIES ON IT AND BRUSHED THEM OFF.
