Service brakes

13 reports
“The contact owns a 2025 Buick Enclave. The contact stated that while driving forward or in reverse, the service brakes made abnormal squealing sounds. The vehicle was taken to the dealer on multiple occasions, where the rear brake pads were replaced and brake lubricant was applied. The dealer informed the contact that the squealing sound would self-correct within 15,000 miles of driving; however, the failure persisted. The failure mileage was 7,000.”

Electrical system

9 reports1 crash
“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.”

Forward collision avoidance

7 reports1 crash
“I was driving and a variety of failure warnings popped up on my screen along with a total brake failure, unable to stop, had to coast until the vehicle was no longer moving. No accident resulted, but it could have been very serious. Mechanics diagnosed it as a loose battery cable.”

Lane departure

4 reports
“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.”

Service brakes, hydraulic

3 reports
“The contact owns a 2025 Buick Enclave. The contact stated that while driving at an undisclosed speed, the cruise control mode became inoperable, and the vehicle unexpectedly shut off. The contact also stated that while driving at an undisclosed speed, messages related to the braking system, forward collision system and the ABS were displayed. Additionally, the ABS was inoperable during inclement weather, and the vehicle became unsafe to drive. The contact pulled over to the side of the road because children were also inside the vehicle. The contact’s husband then drove the vehicle to the dealer, where the failure was duplicated, and several diagnostic trouble codes were retrieved. The dealer informed the contact that the failure was a known issue and that several technical service bulletins related to the failure had been issued. The vehicle was not repaired. The contact stated that the vehicle was unsafe to drive and posed a risk to the contact and other drivers. The manufacturer was made aware of the failure. The failure mileage was approximately 15,000.”
