2017 Buick Envision problems

“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.

“The contact owns a 2017 Buick Envision. The contact stated that while driving at an undisclosed speed, the brake pedal seized. There was no warning light illuminated. The contact forcefully depressed the brake pedal to stop the vehicle. The contact stated that upon restarting the vehicle, the message "Service Brake Assist" was displayed, and the check engine warning light was illuminated. The vehicle was taken to the dealer, where it was diagnosed that the brake vacuum pump and the exhaust camshaft had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 96,000. The VIN was not available.”

“During multiple drives the vehicle completely shuts off when driving or at lower speeds. When this occurs (4 times over the last 3 months) the vehicle has no power or ability to restart creating a major safety issue. You cannot turn on the hazards or anything in the vehicle. The vehicle is still in drive (because you were driving when it occurred) and so you're unable to shift back into park to restart. After some time you are able to restart the vehicle and continue driving.”

“Check engine light is on Turbo is failing, underboost code. Very unsafe on roadway due to unpredictable loss of power. The issue has been diagnosed through my local service center. I have not taken it to a dealership yet but will be next week. The issue occurred three weeks ago I believe”

“Power steering loss. While driving the electronic power steering quit, and I received warnings that the power steering was not working. I also got errors on the advance headlights not working and that the all wheel drive was disable. Drove home with no power steering and checked the power fuses with a volt meter. No failures found. Restarted the car and there was no more problems. The online diagnostic indicated no failures recorded.”
