2019 Buick Envision

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.

The problem started in the past year (2024-2025) with severe shuddering while driving over 35-40 mph and going over a patched pothole or other irregularity in the road. The shuddering would continue until I slowed to stop. It is quite alarming & feels like the car is falling apart and is more difficult to manuever when this occurs. Once I slow to a stop, the shuddering stops and I am able to proceed once again. I mentioned it earlier in the year (2025) when I went for an oil change but dealer was not aware of what it could be. I look for potential road irregularities but sometimes they are unavoidable as it has occurred again recently.
