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.

Woke up to my passenger seat burnt up, liquid oozing out the burnt up seat and wires and metal sticking out. Looks like the fire started under the seat.

I bought this vehicle used to take on a trip with my family. Drove it for a week and seemed to be fine. Got on the other side of Chicago, on interstate 80 (70mph) and the engine started shaking like an earthquake. Had to slow down fast and cross traffic to pull over. As soon as I pulled of the road it stopped, so I restarted. This happened 6 times on way to my destination, with one time in pretty heavy traffic and almost got hit by an 18-wheeler. I took it to a good service center when I got to my destination and he read the Service bulletin 22-NA-211 on this issue and fixed it. Had a safe trip home. From what I understand, the hydraulic mounts leaked and they had to replace bushings. It seems to be a common problem for the 2019 model.

I am seeing that these have been repaired, when in fact it has not been repaired.
