2020 Mazda CX-30 owner complaints

I am experiencing sharp edge on the Driver Side window up button. The Nicle plating is wearing off and causing safety concern. I have images of the concern. Will send upon request. Mazda is suggesting that I take the vehicle in for diagnostics and service. Their diagnostic cost is extremely high, and I am trying to avoid paying the diagnostic fee. Copy of the contents of my email sent to Mazda. I am experiencing sharp edge on the Driver Side window up button. I am wondering if this can be repaired under warranty or, should I report the abnormally to NHTSA to pursue a possible recall to have this switch replaced. I recall NHTSA had a recall on Hyundai vehicles a few years ago for the same issue. Can you please advise.

Check Engine light is on Mazda knows this model car has a manufacture defect based on a 3 page safety report I obtained. Requesting Mazda to repair my vehicle at no charge to me.

New model year and already 1.safety and emission recall 4520f potential fuel leak 2.safety recall 4420f front brake bolts may fall off 3.drive off lot 1/20 and huge air gap with heat system - defective workmanship, 4.ac in summer no good - defective workmanship these issues began in jan 2020, date below may night be exact and more trouble has continued with a/c and now fuel tank recall and brake recall. This is not a safe vehicle anymore. Sent letter to Mazda headquarters with cc to dealership on 8/21/20. To date no response from manufacturer. I want a lifetime bumper to bumper warranty on this vehicle or full reimbursement toward a 2021 model. See image of letter sent. I should not have to worry about the safety of my vehicle with a new model. It is Mazda experiment, not mine.

Instrument gauge cover scratches. This impacts the visibility of the speedometer.

My experience at sansone Mazda was an absolutely nightmare. First off they had me in a lease of 10k down for a payment of 200$ a month, silly me. 7/1/2020 I bought a cx-30, on the floor the man had to jump start the car when I asked why he said it 'was because people play with the system'. The following morning the windshield wiper fluid symbol came up. 9 days later on 7/10/2020 I went to sign the rest of the papers and get the fluid serviced, this is where my headache began. The morning following a tropical storm my vehicle wouldn't start, called a tow truck to bring it back to sansone. Service said my engine was flooded but never took any action to release any of the water, repeatedly saying I was not covered. This same day the shop has closed at 4pm, I had checked my Mazda app and my ho

Driver door cannot be opened from inside with either engine ON or OFF. After I came home from work , I parked the car inside the garage and I could not get out of the car.It took me approximately 2-4 minutes.After that the car just opened. This is the second time in 4 months.

There is a module that should connect to the hatch door to open. That module in no longer available. Without the hatch door opening, in case of side impact and being pushed into something else, there is no way to get out of the car. This poses a serious safety hazard. I have contacted the Mazda dealership and I am told that the part is "retired" and there is no replacement part at this time.

I see this as a potential safety issue. I have been made aware that the only way to open the rear hatch from inside my cx30 requires the need of a flathead screwdriver. Who routinely has this item in their car.

The contact owns a 2020 Mazda CX-30. The contact stated that after starting the vehicle, the instrument panel made an abnormal sound. The contact then noticed that the odometer had inadvertently rolled back to 9,999 miles. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 49,000.

Last night, after we returned home, my wife removed a cup from our vehicle's cup holder. Shortly thereafter, an extremely loud sound of static began to be heard, emanating from the car's speaker system. Regardless of what we did the sound would not turn off, and remained ongoing for a period of about an hour. Nothing happened when we turned the speaker volume down, or turned the car on or off. It was not only loud, but also quite scary. We had the car towed to the dealership, but they indicated that they could find nothing wrong. They, however, also let us know that when they contacted Mazda Mazda indicated that other cars have been experiencing similar problems. Luckily this did not occur when we were driving, because it would have been quite distracting and could have LED to a cra

Rear coil spring broke at ~33,000 miles under normal driving conditions. No warnings given in vehicle safety system and not included in recommended maintenence. Seen when inspected by independent service center. Cannot safely drive vehicle until replaced.

Front and rear brakes premature wear, would have failed safety inspection under 30,000 miles but brakes were inspected just outside of warranty with metal on metal. RIGHT rear coil spring snapped lower middle of coil while driving on flat even ground. Just outside of warranty.

The Automatic Emergency Braking system is activated even if there is nothing in front of the car. The car stops on its own. This has happened 11 times. Yes, my car is available for inspection. I do not know when it's going to happen. My car has malfunctioned like this 11 times. I can get hit from behind since the car is suddenly and unexpectedly braking. The dealership has not been able to reproduce the problem. The local dealership told me that Mazda is aware of the problem, but does not know what is causing it or how to fix it. The first time I brought my car into the dealership for this issue, I was told that Mazda Headquarters instructed the dealership to NOT release my car until I completed their "Unintended Braking form". My car has only been taken to the same dealership th

I was driving car on.the highway and as I prepared to exit I braked and the car hesitated for 2 seconds before brakes engaged. Car has also had hesitation upon acceleration periodically .this has been an issue upon just a few weeks of ownership. The break issue was just recently 7-29-20 I have taken the car to the local dealership about the driving/accelaration issue twice without resolution .

Low Engine Oil Light keeps appearing at seemingly random intervals. I will heat up my vehicle, begin driving, and sometimes after 10 minutes, sometimes after 20 minutes it will come on. I drove 2.5 hours and it did not come on at all. It first started Friday 11/29 and was driven to and from a few places and came on 50% of the time. The 2.5 hour drive occurred on Saturday 11/30 and the light did not come on at all.

The front camera didn't operate properly The brakes have an elongated stopping distance

Driver's side seat belt is too sensitive. Without even stopping abruptly, the seat belt becomes locked making it difficult if trying to lean forward to see if traffic is coming as seat belt doesn't unlock easily. I typically have to unclip the seat belt to let it retract then put it back on. This happens almost daily. Car doesn't have to be in motion either, I can be stopped and not all but most times if leaning forward the belt becomes locked. I've had many cars, none with this issue. Happens when slowing down or stopped and leaning.

Defective windshield. There is visible warping in the windshield and Mazda won't cover the cost of the replacement. This is a known issue.

I own 2020 Mazda cx 30 with 66000 miles. The transmission was shifting with jerky motions. On july 14, 2025 I brought the car to palisades Mazda in rockland county new york to have transmission looked at and to change transmission fluid changed. After I dropped the car off later that day I got a call that the transmission was condemned. I looked on the internet with same year make and model and see there is a big problem with the transmissions on these cars and Mazda is aware of the problem. Tsb 05-002/20 is a bulletin about transmission failures in this vehicle. Mazda is well aware of the transission problems
