Filed Sep 9, 2026FLTransmission & Drivetrain
The vehicle is experiencing premature transmission failure, since about 9,000 miles. Mazda has been dropping the ball at replacing it under warranty and we found out there are 3 other CX-30s that I know of with similar issues. I believe Mazda has a faulty transmission in these cars based off my findings and other complaints.

What is happening with my car are the exact symptoms of the known Mazda Recall 6824H - where the Smart Brake Support suddenly engages for no reason and when it does not need to - which has almost caused me to be rear-ended a few times. This has happened at least 7-8 times since I have owned the vehicle. Apparently, my VIN does not fall under the cars that Mazda reports for the Recall, but nonetheless, my car is still malfunctioning as the Recall describes, which is a safety…

Reporting Product Defect in Mazda Vehicles I am writing to bring to your attention a recurring design flaw affecting current Mazda vehicles, including models such as CX30, MX30, and potentially the Mazda3 series. Following heavy rain or high humidity conditions, there is a consistent issue with the tire pressure sensor alarming and the smart key being unable to unlock the car doors. I have checked my key fob battery, RF function, car battery - none of these are the root…

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? I could have been rear ended because my car automatically braked at an unpredictable time in rush hour traffic with someone very close behind me. Has the problem been reproduced or confirmed by a dealer or independent service…

[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…

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…
