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.

This has happened about 4 times in 4 months. In each scenario I am driving very slowly (3 times forwards, one time in reverse) with no obvious obstacle or crash potential. The brakes will slam suddenly very aggressively, I assume it is the e-brakes as it feels like I hit a wall. It is a safety issue as if someone was behind me it could cause an accident. This is discussed on multiple message boards(e.g. Hard braking without warning! | Chevy Equinox EV Forum https://share.google/EUGSD4XpQzOpnlUwy) but the manufacturer is not acknowledging any issue when contacted. I called the dealer as well and they were not aware of any issues. I have not had the vehicle inspected

BRAKING FAILURE on 2025 Equinox EV LT model - my car has had two separate brake failures going down a steep dry rocky road in clear weather, once with one pedal driving on and once without, on July 21st, 2025 and August 11th, 2025 respectively. It doesn't happen every time going down this road and each time at no more than 5 - 10 miles per hour, with the brake pedal to the floor the car was not slowing down and the weight of the car on the steep track made it speed up considerably which made it dangerous due to the steepness of the hill and turns in the road. The first time I drove off the road onto flat grass and the car came to a stop, the last time it happened I pumped the brakes until the car stopped and the "ABS engaged" light came on the dashboard above the steering wheel. It happened twice on the road that time. There were no prior alerts or warning lights. The car has 5000 miles and is still under warranty, the Chevy dealership had the car for 3 days. The dealership was not able to reproduce or confirm the problem with the brakes. The dealership told me they did a series of resets. They have not given me the written service report yet. I have an appointment to take the car back to the dealer. The brake fluid level is good, there are no current alerts on the dashboard while driving. The car is available for inspection upon request. I am concerned that my wife and I may be injured or killed in a braking failure or that we may injure or kill others or damage property.

Every car I’ve ever owned the cruise control disengages once you touch the brakes and does not reengage without pushing the button to say resume. On several occasions, this car has reengaged sometimes many minutes after I’ve touched the brakes multiple times such as in a parking lot or parking garage going around the corner The car resumes cruise, and rapidly accelerates, which is very dangerous in a parking lot or parking garage

Yesterday while approaching a hairpin exit, all of a sudden lights went on for the Stabilitrack, Collision alert and a number of other lights. Messages popped up saying braking assist was not available, cruise control was not available. Basically, the braking assist was gone and I had to press REALLY hard on the brake pedal to get any slowdown. All regen was gone and it was like driving a car without power brakes. I also got a message saying it would not go faster than 62mph. There was no indication of any issues prior to the Brake assist failure. This put me at extreme risk because it was essentially a power braking failure and it was extremely difficult to slow down. I had to really push hard on the brake pedal. I was able to drive my car back to the dealership where it is sitting now, waiting to be looked at in the morning of 3/24/25. I have attached a PDF of the OnStar diagnostic report, cryptic as usual, but it is a record of the codes that were thrown. Also seems like some modules were not communicating properly. I have also attached some photos of the error messages that were showing this morning.

References: [XXX] [XXX] [XXX] the Equinox EV is currently giving me issues with the brake system. This inconvenience is extremely annoying, frustrating, and most importantly, very dangerous. I'm forced to repeatedly turn my vehicle off and back on, while attempting to re-engage the one-pedal driving. This is a cornerstone advantage of the EV in general, and needs to work 100% of the time, just as my money is taken every month 100% of the time. This also results in other critical features being disabled, such as the auto-hold and forward collision systems. I believe it also impacts the cruise control as well. I am greatly displeased with this and now want to give the vehicle back. My lessor, GM Financial, has specific guidelines in place that make this difficult. What can Chevrolet do to address this? I've heard about the recall, and subsequent remedy, but I'm not satisfied with that, as the issue could occur again. I've lost faith in the vehicle and need to get rid of it. How can you help me do so. Thanks. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
