2020 MAZDA CX-30 Complaints

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.

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.

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

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.

My sunroof spontaneously shattered/exploded during a standstill at a stoplight while waiting to enter a freeway. The glass sunroof panel appeared slightly curved upwards (caused by built up interior pressure?) and the shattered hole is right below my roof crossbar. There is no damage to metal roof surface or crossbar. My interior roof slider was closed when my sunroof shattered as it could have compromised my family's safety. After the incident, I drove my vehicle to the nearest dealership (Capistrano Mazda) but they didn't lift a finger besides taking a couple pics and suggested I call their 800 customer experience center number. Since it was a Saturday, I reached out through Mazda's customer experience email. I didn't hear back from Mazda until 4 days later on [XXX] requesting additional information (address, VIN # & mileage). After providing requested information, I didn't hear back from Mazda until [XXX] suggesting I bring my vehicle back to Capistrano Mazda dealership for a diagnosis. Almost 10 days had passed with no action from Mazda while I still had to commute to/from work dealing with loud incessant cabin noise from shattered sunroof open cavity.

The car was running in parking garage without ignition being turned on. When I entered the car, the motor wouldn't catch at all, and message popped up saying the there was a brake malfunction. All the lights were on, so it did not seem to be a battery problem, but the drive function was dead. Several months ago the car started racing while i was driving and i couldnt get it to stop. I finally, while still driving, turned off the ignition and rolled off the road. After a few minutes, i restarted the engine. it had stopped racing and i drove it to the Mazda dealership. They didnt find anything wrong. So this latest incident, Jan. 3rd, involved an uninitiated running vehicle that was parked, and the brake malfunction console notice that said "brake malfunction". Again, the prior incident involved the same vehicle racing on a roadway and necessitated the turning off the ignition while on a major road and rolling the car onto the shoulder. There is something wrong with this car involving the engine and brakes. Triple A came to tow it to the dealership and utilized an alternator to start it, which enabled them to drive it to the tow truck.

The contact owns a 2020 Mazda CX-30. The contact stated while driving out of the driveway, the steering wheel became firm. The contact stated that the power steering warning light was illuminated. The vehicle was towed to the dealer. The dealer diagnosed the vehicle and determined that the power steering unit needed to be replaced. The vehicle was not repaired. The manufacturer was contacted but no assistance was provided. The failure mileage was 66,000.

Every 1000 miles the low oil light comes on. I have 24000 miles on the car and this only started about 4000 miles ago. I have to add a quart of oil every 1-2000 miles.

I bought Mazda CX30 in 2020 and the battery already starts to fail. The engine light and the battery light are on suddenly when I was driving. Then, after a while, when I restart the engine and it starts to work again. However, it happens for two times within a week. I have sent the car to the Auto Zone and the nearby car auto repair company to check the car. However, they said they cannot detect anything as the engine light and the battery light are on again this time. It is so dangerous when the car suddenly stop in the middle of the road when I was driving. I am so lucky that this accident happened during rush hour and there were heavy traffic.

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.
