2025 Mazda CX-5

On May 21st , 2026, while waiting in line to make a right turn (positioned 3rd in queue), the vehicles ahead moved forward. As I transitioned from the brake to the gas pedal to follow, the vehicle experienced an instantaneous engine stall and total electrical failure (NOT an i-Stop event). Pressing the gas caused the vehicle to slowly roll backward. When I immediately tried to reapply the brakes, the brake pedal became extremely stiff and nearly impossible to press down, failing to hold the vehicle effectively. The driver behind me began honking aggressively due to the imminent collision risk. I attempted to lower the windows to signal the other driver, but all electronic controls were completely dead. I had to quickly shift the gear into Park (P) and hit the start button to successfully restart the engine, which temporarily restored functions.

While driving on February 12, 2026, the steering system failed, resulting in the steering wheel locking and becoming impossible to turn. While making a right-hand turn, the steering wheel suddenly locked. I had to forcefully jerk the wheel to regain control and avoid colliding with a concrete barrier on the right shoulder. After several seconds, the steering function returned to normal. This failure occurred without warning and created an immediate safety hazard due to loss of steering control. The vehicle has been inspected by a dealership, but the issue could not be replicated and no repairs were performed. This condition presents a serious safety risk as it can occur during normal driving maneuvers and may lead to loss of control and collision.

I purchased this vehicle new in June 2025. About a month after the dealer service inspection, the vehicle suddenly would not start at all. The key fob sometimes cannot unlock the door, and I have to use the backup key to open it. After entering the vehicle, the engine will not start. I previously brought the car to the dealer for inspection, but they said no issue was found. Now the problem has happened again and the vehicle cannot start. This is a serious reliability and safety concern for a new vehicle.

The contact owns a 2025 Mazda CX-5. The contact stated while driving at various speeds, the passenger's side-view mirror blind spot detection system sensor was detecting vehicles intermittently. The contact stated that the passenger's side-view mirror blind spot detection system sensor detected vehicles 3 or 4 times in a row, but then a truck drove by undetected. The contact stated that no warning light was illuminated. The contact had taken the vehicle to a local dealer several times. The dealer was able to replicate the failure, but the dealer was unable to repair the vehicle. The manufacturer was informed of the failure. The failure mileage was approximately 4,200.

Critical Malfunction- causing parking brake malfunction, anti lock brake system malfunction, Dynamic stability control malfunction, Disabled blind spot monitoring, Keyless entry system malfunction, Front brake / and obstruction warning disabled, Keyless entry system malfunction, Air Bag system and seat belt pre-tensioner system malfunction. Vehicle not starting./dead. Sat at dealership service where purchased for 6 days saying they could not test bc they did not have a battery tester- Magically when I complained they found one- and say everything checks out ok. Vehicle is not safe!!!! If this malfunction happened while driving I could have been killed. The dealership refuses to anything g but say it’s OK- and it’s not a lemon. I cannot put my life at risk and they will not guarantee it will not happen again- or say why it happened- other than check g the battery.
