Mazda CX-30

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…

What component or system failed or malfunctioned, and is it available for inspection upon request? The automatic braking turned on while I was accelerating. My car is available for inspection. How was your safety or the safety of others put at risk?

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…

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.

[XXX] fuel door assembly has come loose from body. It looks like the clips that hold it in place have become worn or loose by the weight of the gas nozzle or by the fact that the gas door will not close correctly and car wash machine has made it looser and it appears to not shut all the way, and the body colored panel has fallen off as a result and when you pump gas, the assembly moves may be possibly causing it to leak gasoline if the seal or gasket becomes dislodged because of the loose…

The vehicle intermittently fails to start when pressing the push-button start system. The start/stop button becomes unresponsive despite normal conditions (key present, brake engaged, no warning indicators preventing ignition). This has now occurred twice within two years of ownership, indicating a recurring issue rather than an isolated incident. On the most recent occurrence, the vehicle was completely unable to start and required towing. The tow truck operator reported that he had towed…
