2017 Buick Envision brakes problems

Filed Jul 22, 2026 · Brakes, Electrical · MI

When I stop at traffic lights, my car does not immediately turn back on (it has the auto stop feature). It flashes "parking brake released" on the dashboard. Then, it starts back up. Sometimes, it has not started back up right away & the steering wheel seizes. It has also said, "Assisted Steering Reduced" & "Stabilitrack Not Engaged (or something to that effect)." When the issue started, I tried to start my car & it said to put the car in park but it was already in park. I tried repeatedly to put it drive to put it back in park & it did not register that I was shifting gears. I turned my car off & turned it back on & it shook violently. So I shut it off immediately. The safety hazard is that my car has shut off on me while I was driving, wheels turning, car in drive, going down the street! It came right back on thankfully, but the way it shut off, I would not have time to brake & let driver's behind me know there was an issue, if it had not come back on! Also, if I have to full stop somewhere in the middle of traffic or an unsafe space, and the auto stop does not restart, that is another safety hazard. The problem started December 2025. I stopped at a light & my car would not restart. I was told it was the starter. I had the starter replaced & the issue returned July 4th weekend. Now, I try to brake in a way to prevent the auto stop from engaging as much possible. I shouldn't have to do that!! Please notify General Motors to recall & fix whatever this issue is with the Buick Envision to keep our families & roads safer!! Thank you!

October 2023 my brake on the drivers side ruptured that let to the master cylinder. Lost brake pressure and all brake fluid resulting in no braking ability at all. May 9th 2024 took my vehicle for scheduled maintenance and was told vehicle was in excellent condition. 20 days later the brake line on the passenger side ruptured leading to the master cylinder resulting brake fluid leakage and no brake performance. This issue is a previous recall and should be reinstated. I've spent twelve hundred dollars on repairs for an issue that publicized as an open recall. I could have lost my life and Buick GMC refuse to do anything about it.

The vacuum pump failed, causing the gear to explode, which in turn damaged the cam shaft. Yes, this is available for inspection. The brake was unable to be depressed, requiring extreme force to being able to safely stop at an area that was safe to do so. I turned the car off and it made a funny sound. When I tried to start the car, it would no longer start. The car was towed to my local auto mechanic and then to the closest Buick dealership. The dealership diagnosed the problem outlined above. No warning lights.
