But it seems to operate properly in a straight line. I have spoken with Mazda Customer Service several times. The 1st …

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. Despite consulting local dealerships and various Mazda forums, no …
