“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 cause. …”
NHTSA complaint #11757051, filed 2026-08“Since purchasing the vehicle, the braking system has activated on its own for no reason. Today, Oct 19, 2026, it was cold and it said the system was failing. My camera system fails when it rains. My 2024 Mazda CX-30 has 62,000 miles and is experiencing the exact catastrophic phantom braking and forward camera failures detailed in NHTSA Recall 24V649000 (Mazda Campaign 6824H). My VIN is currently excluded from the recall campaign, but the vehicle is a severe highway safety hazard due to spontaneous unprovoked braking”

The start/stop button becomes unresponsive despite normal conditions (key present, brake engaged, no warning indicators preventing ignition).
