The contact owns a 2026 Chevrolet Equinox. The contact stated that while driving approximately 10-15 MPH in stop-and-go traffic, while changing lanes, the automatic emergency braking system engaged unexpectedly, causing the vehicle to stop abruptly with a forceful back-and-forth movement of the head and upper body of the driver. The contact sustained neck and left shoulder pain, which progressively worsened. The vehicle was taken to the dealer, where the Forward Collision Avoidance sensor software was updated to increase the trailing distance. The failure mileage was approximately 4,000.

This car locks up sometimes while driving in normal traffic which is very dangerous, resulting in a whiplash for me the driver and almost causing rear end collisions to my car from the abrupt stop in moving traffic. All five abrupt stops happened with all the collision warning systems on. Three happened between 2/1/25 and 8/1/25. I called GM onstar to report two of them. After the third event I switched all braking systems to alert only from brake and alert. Two recent events happened between 10/8/26 and 10/13/26 after I had my car serviced for a GM safety recall N25252824 Brake System Control Module on 10/7/26. I switched all brake systems to brake and alert assuming that GM had fixed this issue. Both recent events were during light rain. I called Onstar to report the second event and brought my car back to the Chevy dealer on 10/15 for review. This issue is abrupt, with no warning. The car simply locks up no matter the speed. The issue is well documented and is all over the Equinox EV forum. I am speaking to a law firm as well about the issue. Thank you.

The driver pulled into a parking space at a local pharmacy. The space directly faced the building and was separated from the building by a sidewalk that was approximately 6 feet wide. After pulling into the parking space and releasing the accelerator (the vehicle was in the single pedal driving mode, so the motor braking should have been activated) the vehicle instead experienced three problems/failures. (1) Sudden Unintended Acceleration - The vehicle suddenly lurched forward without driver input. (2) The Automatic Emergency Braking System failed to activate or to override the acceleration command, even though the vehicle was directly facing the wall of the building, which was only a few feet away. (3) The Collision Warning System failed to activate. The system should have displayed a large red box with an X through it in the Heads Up Display to warn of the pending building impact. No warning was received.

On May 9, 2026, while pulling into a parking garage parking space at low speed (below 5 MPH), the brake pedal was pressed but failed to engage or slow the vehicle. The pedal was pressed completely to the floor with no resistance, and the vehicle continued moving forward until it struck a wall, causing damage to the vehicle. Earlier the same day, the brakes produced an abnormal hissing sound while pulling out of a parking space. No other symptoms or abnormalities were present prior to failure. The vehicle may also have recently received a software update, although it is unknown whether that is related to the incident. The failure appears to involve the brake system and the driver safety assistance systems equipped on the vehicle like forward collision alert, automatic emergency braking, and Dynamic Brake Support systems. The exact failed component is currently unknown and remains under inspection by a Chevrolet dealership. No warning lights, messages, or audible alerts appeared before, during, or after the incident. The automatic braking/collision avoidance system also did not activate. Because the vehicle had no braking capability at the time of the incident, the occupants and nearby pedestrians were placed at risk of serious injury. On May 10, 2026, the vehicle was taken to a Chevrolet dealership for inspection. The dealership has been unable to reproduce the issue, and no mechanical defects or diagnostic trouble codes related to the incident were identified. On May 13, 2026, the issue was escalated to the GM Technical Assistance Center (TAC) for further review, and the vehicle remains at the dealership awaiting a response to the TAC case. The dealership acknowledges similar brake-loss concerns referenced in GM service bulletins involving the 2025 Chevy Equinox and other models, including bulletin N24471431, although they stated the bulletin does not apply to this specific VIN.

The contact owns a 2026 Chevrolet Equinox. The contact stated that in the first month after the vehicle was purchased, while driving at an undisclosed speed, the Forward Collision Avoidance system failed to function as intended.

When there is dew, condensation, or rain on the windshield, the Front End Collision Warning system becomes inactive and displays the message: "Front End Collision System Inactive-Clean Windshield." This happens frequently, even with light moisture, and the warning system remains disabled until the windshield dries completely. Given that wet or low-visibility conditions are precisely when collision avoidance features are most critical, this failure creates a serious safety risk. I have verified that the windshield is clean and that three are no obstructions on the camera or sensors. Despite this, the system consistently deactivates whenever moisture is present. This issue appears to be a design or sensor calibration problem, not a maintenance issue.

While driving, all my displays which includes speed and car warning indicators, went blank and the red light (collision warning) started flashing as if there was something in front of my car, but my car acted fine. I pulled over and then everything slowly came back on. The car continued to run just fine. It was just both displays went totally black and then the red collision warning lights were flashing. Car never turned off. Never had to restart car. No resets performed. Displays came back on after a short period of time. Interesting, the radio and volume had to be turned back on. Acted as if displays rebooted, but did not affect car mobility.
