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.

The factory adhesive/anti-flutter sealant that bonds the outer hood skin to the inner structural frame has physically separated. There is a clear gap where the outer panel is no longer attached to the frame. As a result, the outer hood skin flexes and vibrates, especially at highway speeds. Impact / Safety Concern: The vibration and movement of the outer hood panel occurs directly in the driverâs forward line of sight. This creates a visible distraction while driving and can draw attention away from the road. Because the outer skin is no longer properly bonded to the structure, the condition is progressive and may worsen over time. Dealer Response: I documented the adhesive separation on…

The drivers side inside door handle has quit working twice. The dealer has temporarily fixed it both times, but advised us to "just be more gentle with the handle". The cable is falling off of the door hinge inside the door, and the dealer claims they don't have a way to permanently fix it. They just put it back on its mount. We are afraid that the driver will not be able to escape the vehicle in an emergency. Both instances have been under 10,000 miles. The door handle works perfectly fine until it doesn't work at all. No warning given.

The automatic emergency braking in this vehicle is faulty. It misinterprets obstacles and uses the emergency braking inconsistently. I park in a parking garage and I have to slowly (less than 5 MPH) drive up any ramps because it apparently sees the ceiling of the garage as a obstacle and as a result, will randomly brake with no notice (which feels like getting rear ended). The dealer said it is working as designed and said I can turn this function off, but I have to turn it off every time I start the car. I also updated the sensitivity t the lowest setting, which didnât help. Iâm worried about this issue happening when Iâm in traffic or bad weather and what might occur, like an…

"My 2025 Mazda CX-50 began overheating while still under the factory warranty. During one incident, the engine lost coolant and overheated. I immediately shut the engine off to prevent damage. The vehicle continues to overheat, and the air conditioning only cools properly while the vehicle is moving. When stopped or idling, the A/C stops cooling. I have reported the issue to my Mazda dealer and opened Mazda Customer Experience Case Number 00473077. The problem remains unresolved despite multiple attempts to obtain assistance. I am concerned this condition presents a safety risk." "The vehicle has been inspected by an authorized Mazda dealership on two separate occasions. The dealership kept…

While driving my 2025 Mazda CX-50, the entire center-dash climate control panel (HVAC module) suffered a sudden, spontaneous, and total electrical power blackout. The unit completely loses power and goes dark exactly as if the power button was pressed. This is a recurring failure that occurs after only a few minutes of vehicle operation. This electrical failure immediately cuts all airflow and A/C cooling to the cabin. The unit can temporarily be turned back on manually, only to black out and fail completely again minutes later. This represents my second consecutive modern Mazda vehicle to experience an early-mileage HVAC hardware/electrical failure (previously a CX-30), indicating a…
Jul 27, 2026SuspensionCrash1 injury
The vehicle was traveling at highway speeds when it experienced a sudden, violent lateral jerk to the side, causing immediate side-curtain/seat airbag deployment prior to impacting the center divide. I believe there was a sudden, catastrophic mechanical failure of the front suspension componants causing a partial detachment of the front driver's side wheel. This failure mirrors the exact defect described in NHTSA Campaign 24V834000 / Mazda Recall 7925J regarding un-torqued front suspension fasteners. We believe our vehicle suffered from this exact factory build issue despite falling outside the initial recalled VIN list. Insurance claim to follow.
