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.

The sunroof exploded without warning. Driving 57 MPH on a 55 MPH road, it was a sunny day, there were no cars around me and there were open fields on both sides of me. My daughter (17-years old) was starring up at the sunroof when the sunroof exploded.....And it sounded like a gunshot. Manufacturer would not warranty the sunroof as I could not prove the glass was not broken by an object.

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.

The Automatic Emergency Braking (AEB) system activates unexpectedly and dangerously. Incident 1 5/7/2026: While driving approximately 2 mph in a drive-thru and rounding a curve, the vehicle suddenly applied full braking without warning. The braking force was severe enough that I struck my face on the steering wheel and my child was thrown forward in a secured car seat. Incident 2 5/19/2026: While merging onto a busy road behind a semi truck, the vehicle again applied sudden hard braking after I safely merged. This caused the vehicle behind me to nearly rear-end me, creating a high-risk traffic situation. These events occurred with no obstacle or reason that would justify emergency braking. In addition, the vehicle developed a coolant leak around 20,000 miles, raising concerns about overall reliability and potential related system issues. The unexpected braking presents a serious safety hazard and increases the risk of rear-end collisions and injury. The vehicle is being brought to a dealer for inspection, but the issue is intermittent and may not be easily reproduced.

The car frequently just slams on the brakes on its own when reversing. Doesn’t matter the speed, and nothing is behind me at all. It also triggers a check engine light with transmission errors if you get a car wash and it is even mildly cold. Transmission errors when it gets too cold or snow in the grill.
