2025 Chevrolet Blazer Driver assistance Problems

The contact owns a 2025 Chevrolet Blazer. The contact stated that the vehicle experienced repeated phantom braking while driving at various speeds. The contact stated that the automatic emergency braking system activated erroneously. The automatic emergency braking system was deactivated to prevent the failure; however, after a software update at the dealer during a radio repair, the feature automatically activated. After the update, the phantom braking reoccurred on several occasions. The contact had successfully disabled the feature again but remained concerned that the system might activate unexpectedly while turned off. The failure mileage was approximately 10,000.

I am concerned about a significant safety issue with my 2025 Chevrolet Blazer EV. On at least four separate occasions, the vehicle has unexpectedly applied extremely hard Rear Automatic Braking while I was backing up, despite there being no object, vehicle, person, or obstacle behind the vehicle. The braking is so abrupt and forceful that it feels as though the vehicle has collided with something. Because the driver is typically looking over their shoulder while reversing, the sudden stop causes a violent jolt. This has resulted in neck pain and headaches for me and my son on multiple occasions. One of these incidents also occurred while my son was driving the vehicle. We discussed the event afterward and both experienced the same sudden, aggressive braking with nothing present behind the vehicle. The system appears to be activating falsely. This is a serious safety concern. The unexpected braking could potentially cause injury to the driver or passengers and may also create a hazardous situation if another vehicle is following behind. I am requesting that this issue be investigated and repaired as soon as possible.

The contact owns a 2025 Chevrolet Blazer. The contact stated that a GM inspector had inspected the vehicle due to phantom braking. The contact stated that while her husband was driving approximately 35 MPH, with her daughter in the front passenger’s seat and the contact seated in the rear seat, the brakes independently engaged, and the vehicle came to an abrupt stop. The failure had occurred three times. The contact had undergone cervical spine surgery six months before the failure, and the failure caused the injury to return. The contact's husband reviewed the Owner's Manual and discovered that the vehicle was equipped with the Automatic Emergency Braking (AEB) system and associated the failure with the AEB feature. The manufacturer was notified of the issue, and a GM inspector inspected the vehicle. The vehicle was also taken to a local dealer; however, the dealer was unable to repair the vehicle and suggested that the feature was deactivated.

The contact owns a 2025 Chevrolet Blazer. The contact stated that the Forward Collision Avoidance system had erroneously activated on several occasions. While driving very slowly, the braking system suddenly activated while leaving a dealer. Additionally, while driving approximately 30 MPH, the braking system erroneously activated, causing the vehicle to abruptly stop. The automatic braking system was turned off, and the vehicle was later driven to the local dealer. The local dealer was unable to determine the cause of the failure and advised to deactivate the Collision Avoidance System. The contact sustained a neck injury during the failure while seated in the driver’s side rear seat. Medical attention was required. The failure mileage was 7,000.

Just purchased a used 2025 RS EV on 5/2/2026. When I got home I found out the Google maps and on star app wasn't working. Called on star and they can't connect to the car and that the telematics module is probably bad. Checked my Chevrolet app and it reports that it hasn't connected to the car for over 6 months. Now waiting for replacement part going 3 weeks now. A little pissed off that dealer did find before they sold me the car.

The vehicle accelerated without input and the brakes failed to respond. I am notifying you that this vehicle is a life-threatening safety risk and should not be rented again until a master technician clears the electronic throttle control and breaking system. This condition presents a serious safety risk and could lead to a car crash or injury. Additionally, the vehicles, climate control system behaved erratically, alternating between extremely hot and extremely cold air without adjustment. This may indicate a broader electronic or system malfunction affecting vehicle city.
