NHTSA Complaint #11683225 — 2025 CHEVROLET EQUINOX EV

I experienced a brake failure this past weekend in my 2025 Chevrolet Equinox EV LT while descending a dirt/stone road. The moment we started descending, the ABS system engaged and did not brake the car adequately. In my opinion, the ABS system should not have engaged in this terrain. The ABS, would not shut off for our entire descent, which lasted for about two full minutes. During this time, we could not stop the car and were accelerating out of control. We got going far faster than I was comfortable with, and my passenger & I thought we were going to end up crashing. After about a minute of inability to brake properly or stop, we ended up getting a flat tire. The flat tire, combined with the terrain flattening, eventually helped us come to a complete stop. After stopping, the car was also having software issues (infotainment system resetting), and the infotainment system was very hot to the touch, suggesting an electrical or software malfunction tied to the braking system. It was a very scary situation, but my passenger and I were not injured. This failure left me and my passenger completely out of control of the vehicle, with a high risk of collision, rollover, or serious injury. In my opinion, a braking system that does not stop the vehicle when the pedal is fully applied constitutes a critical safety defect. Chevrolet has been contacted, but the dealer refused to treat this as a warranty safety issue so far. The vehicle remains available for inspection.
