Power Train · reported Nov 11, 2026
My 2021 Mazda3 2.5 Turbo AWD experienced major drivetrain component failures at approximately 65,800 miles. Hiley Mazda of Fort Worth inspected the vehicle and diagnosed failures involving the rear differential and coupling assembly, transfer case, and driveshaft. The dealership recommended replacing these major drivetrain components, with a total repair estimate of $12,107.35. I am concerned that multiple critical AWD drivetrain components have failed at such relatively low mileage. A failure involving the differential, transfer case, or driveshaft could potentially affect vehicle propulsion…

Radiator leaking coolant requiring replacement at 60k miles. Mazda updated the part which means they know it's bad, should be fixed for free for all affected owners.
Electrical System · reported Oct 13, 2026
While driving to work, the dashboard displayed “Charging system malfunction, pull over.” The driver pulled over safely. The vehicle has electric power steering, so a loss of charging power while driving could reduce steering assist and cause the vehicle to stall in traffic. This happened three days after a Mazda dealer replaced the front passenger-side lower control arm. That part had failed at 111,777 miles, causing clunking under braking and making the car unsafe to drive (previously reported to NHTSA). This is the second safety-related failure on this vehicle in two weeks. The vehicle…

Yes Component: Suspension: Front (Lower Control Arm) Description: The front passenger-side lower control arm on my 2021 Mazda3 failed at 111,777 miles. The car began clunking loudly when braking and while driving. My mechanic inspected the car on a lift, identified the lower control arm as the source, and told me the car was not safe to drive. He suspects a failed or defective part. A bolt…
Service Brakes · at 45,946 miles · reported Sep 28, 2026
Car made grinding sound with notable vibration when starting to move after shifting into drive. Felt like brakes weren't releasing. Had car towed to dealership where they diagnosed that the front left brake shim was damaged and making contact with the rotor, had to pay to fix it out of pocket.
