2025 Chevrolet Equinox

On Th, Nov 6 ~1700, the 25 Equinox EV being driven encountered an electric drive failure and brake failure, including friction brakes. This Equinox EV is essentially still brand new with 3900 miles and no accident history. The vehicle was driven off the EB SR 528 exit ramp to Narcoossee Rd in Orlando and driven to the stop light at the WB on ramp. After the light changed and began driving, the vehicle console reported an exception with drive assist. At this time the driver attempted to slow down to take stock of the situation and the vehicle accelerated, at which time the driver took their foot off the brake pedal and attempted to identify a place to take the vehicle off the roadways. Thankfully a stoplight at McCoy Rd was green and the driver continued through that light and while attempting to brake, the vehicle accelerated instead. The driver then coasted, maneuvering the vehicle was into the Vista Palms commercial center. The vehicle, unresponsive to braking, propelled through a stop sign into the Kohl's parking lot at which time the driver began looping around the lot until the weight of the vehicle brought the motion down. While the vehicle was stopped, it rotated through warning messages indicating..forward collision, brake assist is reduced, steering assist is reduced, then finally Service Transmission Now Unable to Shift Soon. The vehicle was towed by AAA to AutoNation Chevrolet Airport in Orlando. Technicians found codes U1610 and U1639, and found K160 connecter unseated. It was reseated and greased. The concern is that this should have been locked and unable to be unseated. Is this an indication of manufacturing problem or operating problem? All braking was dysfunctional. How can we be certain that this was not a one off event?

I was driving my 2025 Chevrolet Equinox EV on the highway with Adaptive Cruise Control (ACC) engaged. The vehicle was also set to "One-Pedal Driving" (High regenerative braking). The vehicle in front of me slowed down abruptly. My vehicle's ACC began to slow the car, but it was not decelerating quickly enough to avoid a collision. I immediately intervened by pressing the brake pedal as hard as I could, pushing it completely to the floor. Critical Safety Failure: The vehicle's physical brakes failed to engage. Despite my foot being pressed hard to the floor, the vehicle did not slow down. It felt as though only the regenerative braking was (slowly) working and that my manual brake application had zero effect. The vehicle continued to glide forward with no significant braking power, and I was unable to stop the car in time, resulting in a collision with the rear of the vehicle ahead. Summary of Defect: The primary safety failure was the complete lack of response from the manual brake pedal. My attempt to override the vehicle's automated systems in an emergency was unsuccessful, as the brake pedal was unresponsive. Reporting History: I have already reported this incident to my auto insurance, my local Chevrolet dealership, and the Chevrolet Customer Assistance Center. A representative from Chevrolet recommended that I file this report with the NHTSA to help identify and track similar safety-critical incidents.

Vehicle may be involved in GM Service Update N252494220 , Reduced Brake Performance. I cannot get a response from Chevrolet if the vehicle is part of the brake problem issue. Based on the information provided, this should be escalated to a recall. I also have not been able to get an answer from the selling dealer. Per the information in the Service Update bulletin, the vehicle was not to be sold until it was inspected for the problem.
