Filed Sep 30, 2026 · Brakes, Electrical · 38,000 miles · AL

The contact owns a 2025 Buick Enclave. The contact stated that while driving 10 MPH, the brakes suddenly failed with the "Brake Assist Failure" and "Service ESC" warning lights illuminated. After restarting the vehicle, the contact received a secondary message that the vehicle would be limited to 45 MPH, with an instruction to press the brake pedal very hard. The contact stated that the brake pedal felt extremely squishy and unsafe to operate because it failed to operate properly. On a separate occasion, the vehicle shut off without warning, with a very loud clicking sound coming from the vehicle. After several attempts, the vehicle was restarted, and the audio and electronics functioned as needed for minutes of driving. The vehicle was taken to the dealer for the electrical failure, and the technicians attempted a telematics control module reprogramming. The dealer stated that the module was already updated but discovered that the module was no longer communicating, which created several issues. After restarting the module, the vehicle was temporarily repaired. The vehicle was taken back to a local dealer but was not yet diagnosed or repaired. The failure mileage was 38,000.

Driving at 30mph and all the dashboard lights turned on and all the warnings kept popping on the dashboard and 30 seconds later the brakes were not working when I was approaching a busy intersection. I was able to pump the brakes and stop the vehicle and put it in park and the vehicle shut off and nothing would work - not even the hazard lights. The vehicle is currently at the dealership being assessed.

Digital dash display is completely black. There is no display of speed, lane departure, back-up camera or parking assist/surround view camera. Neither vehicle restart nor software reset corrects the issues.

I wanted to update a previous report. The vehicle had had some odd electrical issues. The brakes ended up failing while driving but no electrical issues at the time proceeding it. What I wasn't able to report before was that the brake pedal sunk to the floor with no effort to stop the vehicle at all. The emergency brake is a button on the left side of the vehicle which was attempted to be engaged to stop. It made no effort to stop whatsoever. The vehicle is a danger to society. I just got it back from the dealership and they made an update to the computer or console but replaced no parts. These all need to be recalled no one should be driving these.

The wireless charging tray on my Enclave gets the phone very hot. It gets so hot that my phone shuts down. This happens with Pixel, Samsung and Apple devices. There are several reports on the web regarding this issue. I even tried to charge my phone without a case same issue. This is a concern because it can cause a vehicle fire. The batter gets so hot that it can easily catch on fire

Completely lost all power brakes while on the road today. Owned it for about 11 months. Looking like the master cylinder. We've been having random electrical issues when we're cranking it up. Weird sound coming from the dash when the AC is on on occasion. Like the car wasn't fully kicking over even though the engine was running. Sometimes turning it off and turning it back on would make it work.

Check engine light came on first and then the infotainment went blank for three days. Took to dealership for the software update which shut the infotainment system down completely.
