2025 Mazda CX-50 Transmission and drivetrain Problems

“I am reporting a potential safety-related defect in my 2025 Mazda CX-50 Preferred, which is approximately four months old. On one occasion, the vehicle moved backward while in Drive mode. This occurred twice on the same day under similar conditions on a slight incline. After starting the vehicle, I shifted into Drive and applied acceleration; however, the vehicle moved backward instead of forward. The rearward motion continued despite active acceleration input. This behavior is not consistent with normal rollback on an incline. …”

“After about six months of ownership, a knocking noise started happening from the front of the vehicle when turning the wheel all of the way to the right. A month or so later I brought it to a Mazda dealership in Green Brook, NJ. I was told by the service advisor that she had the same vehicle and was advised that this was normal.

“I brought my vehicle to Safford Mazda of Fredericksburg on Monday, December 15, 2025 due to a front-end clunking that occurs during left or right turns.

Shortly afterward, I was informed that the front axle has internal damage and that the vehicle would need to be retained by the dealership for repair. I was told the necessary parts would not be available until sometime in February 2026. The dealership retained possession of the vehicle and arranged a loaner vehicle for my use. …”

“The rear differential makes a grinding, clicking noise when traveling at low speeds and especially when turning. After a fluid change the on the differential, a large amount of metal fragments were visible in the oil. Also causes rear wheel hop on sharp turns. This is a known issue amongst CX50 owners but Mazda refused to acknowledge an issue. The issue started for me around 40k miles. Just outside the warranty period.”
