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.

What component or system failed or malfunctioned, and is it available for inspection upon request? On September 12, 2026, while parked at the top level of a parking garage, the vehicle unexpectedly began rolling forward after being parked and exited. The vehicle subsequently struck a concrete wall. The vehicle is available for inspection upon request. How was your safety or the safety of others put at risk? On September 12, 2026, my son parked the vehicle on the top level of a parking garage. He exited the vehicle while I remained seated in the rear seat and his girlfriend remained in the front passenger seat. I later moved to the driver's seat to speak with her. As I exited the vehicle to meet my son, the vehicle unexpectedly started rolling forward on its own. Nothing was touched or intentionally activated prior to the vehicle moving. Because the vehicle began moving while I was exiting, I fell and suffered injuries including a scraped knee, swelling and injury to my foot, pain in my hands, and abrasions on my arm. The vehicle continued rolling and struck a concrete wall, causing damage to the front of the vehicle. The unexpected vehicle movement placed me, the passenger, and other nearby individuals at risk of serious injury. Has the problem been reproduced or confirmed by a dealer or independent service center? I am reporting these incidents for investigation. The vehicle is available for inspection by Chevrolet, the dealer, NHTSA investigators, insurance representatives, or other authorized parties. No warning lamps, messages, or other alerts were observed prior to the Rear Automatic Braking events or the vehicle roll-away incident. The braking events and vehicle movement occurred unexpectedly and without warning. I no longer feel safe operating this vehicle. Between the multiple false activations of the Rear Automatic Braking system and the incident on September 12, 2026, where the vehicle unexpectedly rolled forward and caused injury

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 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.
