2025 Mazda CX-50 forward collision avoidance problems

What owners report

• “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 star…”

• “When approaching cars at an intersection, the brake warning does not give any warning, but the cars brake, lock up, and throw me and anything in the seat flying into the floor or side compartment. It was not even necessary to stop that quickly. Totally random and could cause an accident.”

• “Emergency brake came on as I was backing out of parking space, pausing to double check for traffic not seen on camera. The emergency brake froze on "on" and car was stuck, unmovable, in traffic lane. The emergency brake would not release when put in reverse or drive. The same problem happened again the next day in forward. Two different dealers were not able to duplicate the problem. No warning lights came on.”

No cars in front of us. 2) Driving on the expressway with the cruise control on. Driving 75 miles an hour and the vehicle goes to 30 miles an hour and I have to accelerate. Thank the Lord no one was behind me. This has happened 3 times. I took it into Mazda and tool them the issue but they just did their regular maintena…”
