2025 Mazda CX-50 problems

“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.”

“On XXX, I was driving my 2025 Mazda CX-50 Hybrid in stop-and-go traffic in [XXX]. While driving in traffic, the vehicle suddenly accelerated without my intention. I applied the brake pedal in an attempt to slow or stop, but the vehicle did not decelerate as expected. Despite my attempt to brake, the Mazda collided with the vehicle ahead of me, resulting in a multi-vehicle collision. Following the initial impact, my vehicle moved backward and struck another vehicle behind me. I experienced a forceful backward movement and felt as though I had been thrown backward. The airbags deployed. Police and emergency medical personnel responded. A child passenger sustained a small cut to her head and was medically evaluated. The police report includes a witness account describing the Mazda's sudden acceleration before the collision. I am concerned about possible unintended acceleration and braking-system performance. The specific mechanical or electronic cause is UNKNOWN. I have not received confirmation that a particular component malfunctioned. The vehicle was declared a total loss by my insurance company. It was expected to be transferred to a Copart facility. I do not…”

“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 didn’t help. I’m worried about this issue happening when I’m in traffic or bad weather and what might occur, like an accident. I’ve talked with other users of this same vehicle and they have ran into similar issues. Based on my experience, I think the system is defective and is a safety issue.”

“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 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.”

“The vehicle experienced a total electrical blackout, refused to start for hours, and threw a U0115 (Lost Communication with ECM/PCM B) network code. I consider this an extreme safety hazard because a communication failure of this specific kind risks causing an unexpected engine shutdown or total loss of motive power while driving. This car only has 8,500 miles on it, so a problem this severe this early is extremely concerning!”
