The vehicle experienced a premature internal A/C failure, resulting in a total loss of climate control refrigerant. Because the A/C system failed, the vehicle's windshield defroster completely stopped removing humidity and moisture from the cabin air. This caused the front windshield to instantly and severely fog over while operating the vehicle completely obstructing forward driver visibility. The manufacturer has issued Technical Service Bulletin (TSB) MC-10203760-0001 for factory evaporator defect on 2021 models, acknowledging low refrigerant charge due to component leakage. However, the manufacturer's current TSB VIN cutoff is too narrow. My vehicle is a 2021 model built at the same facility experiencing the exact same component failure past the arbitrary cutoff, proving the dangerous defect extends into later production runs. The current parameters must be expanded to protect public safety and a recall needs to be initiated to fix the issue.

On June 3rd, 2026, about 1:15 PM, I braked in the rain because there was a stopped car in front of me. The brakes did not work; the Automatic Emergency brakes did not work; the Forward Collision Warning did not work and I hit the car in front of me causing a 3 car accident. As I hit the car I saw the Forward Collision Warning come on and then go out. Unfortunately, the brakes worked after that and the Mazda Collision Center cannot find anything wrong with the brakes. I note that the 2022 and 2023 models of the same car did have recalls related to the brakes. The claim is still open and I have not yet received the final damage report. Yesterday I was told the revised estimate is $16,000 and my car and the middle care with front and rear and damage are considered totaled.

Following a recent inspection at Perry Mazda in Santa Barbara, my vehicle was diagnosed with a failed clock spring mechanism causing airbag malfunction warnings. Clock spring failure under 70K miles on a 2021 vehicle is premature and suggests a defect rather than normal wear. I contacted Mazda North America and it has been over a week without a response. I have maintained the vehicle responsible and have no history of collisions or modifications that could have contributed to this failure.

While driving, on approach to a stop signal, at an intersection the car stopped moving. The display said engine malfunction, have inspected. The electronics and engine continued to operate, but the car would not move when gas pedal was depressed. I shut off and restarted my vehicle numerous times, with no effect on the problem, the car still would not move. The vehicle behind me had to brake unexpectedly, and I could have been hit by others in the intersection, there could have been an accident.(I put car in neutral and the driver behind me, pushed my vehicle, manually, out of the intersection) AAA towed vehicle to the dealer I purchased it from, they were unable to reproduce the problem or retrieve codes to identify problem.( AAA did something under the hood before towing and I was able to drive vehicle to nearby parking lot to be towed) No other inspection has been conducted. Over prior week I noted intermittent engine revving while driving for very brief seconds and this occurred just prior to the incident that resulted in the inability to move the vehicle.

Lane DepartureMar 2026 · ODI 11721948Details +Close −
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.

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!

Latches/Locks/LinkagesOct 2024 · ODI 11622433Details +Close −
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.

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).

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.

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.

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.

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.

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?

Vehicle Speed ControlJun 2023 · ODI 11525939Details +Close −
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.

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.
