There are 3 owner-reported powertrain & transmission complaints for the 2025 Buick Enclavein NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
My wife's 2025 Buick Enclave with less than 10,000 miles (around 9,800) stranded us on the highway. Transmission was shuddering and felt like we were hitting rumble straps on acceleration. Then, we couldn't go over 18 mph, then it just stopped. Couldn't even pull off to the side of the road because the electronics wouldn't let the vehicle go into neutral to allow us to push it onto the shoulder. Eventually we got it off the Interstate to a residential area. When tow truck arrived, they couldn't get it into neutral and had to drag it onto the wrecker with generous amounts of WD-40. That can't be good for the vehicle. The vehicle is at Randy Wise Buick in Fenton, Michigan. We were lucky not to have been hit on the Interstate. Biggest worry is not the transmission problem but that we couldn't even push it off the roadway.
While slowing down with foot of accelerator, to stop at an intersection, the rear wheel’s momentarily locked up.
