2017 Buick Envision

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!

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.

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.

I was returning home from shopping. As I approached a stop sign, I applied the brakes and the brake pedal went completely to the floor: Fortunately, I was able to stop before entering the intersection. I had the vehicle towed to a nearby Buick dealer to determine the cause of the brake failure. I was told the left front brake line had a hole in it causing total loss of brake fluid - cause unknown. There were no warning lamps or other symptoms of the problem prior to the brake failure. The brake line was replaced by the dealer at significant cost to me.

Driver front brake hose burst, mechanic placed back in packaging for me to keep for inspection. Fortunately it busted coming to a stop for traffic light while already slowing, then could slowly drive off roadway into a parking lot, brake pedal went to the floor due to loss of fluid and could have been catastrophic for my wife or other motorists. My mechanic replaced with factory GM hoses on both sides. My mechanic is a state of Maryland licensed inspection station and confirmed the failure. No prior warning, Onstar records will confirm, after the fact, of lights and warnings of brake failure.

Car keeps jolting forward on it’s. This almost caused me to slam into the back of someone’s car on the highway in bumper to bumper traffic. While trying to slow down the car forcefully slams forward. Other times I have been trying to accelerate from a stop and the car slams forward. When this happens everyone is thrown forward this started happening after repair at Jack Gimbalvo Buick body shop in York. Jack Giambalvo Buick dealership said they can’t duplicate the problem and there are no misfires. I will be calling corporate to make another complaint. I have already been in an accident in this car due to the brakes not working correctly and the whole dash malfunctioning.

The brakes went to the floor with very little stopping power. Took the car to the dealer and the left brake line failed. The dealership said they thought since there was minor damage to the left front of the car, that this was the cause of the failure. The brake line was replaced with an aftermarket part and brake lines flushed and replaced. We had another instance of brakes going to the floor with little stopping power. This time the right side brake line failed. The dealership noticed that there was no damage on the right side of the car to cause this failure. The dealership told me they sent an email to corporate and checked for a recall on the brake lines. If this car would have been on the highway when either of these failures took place, we might be having a different conversation. I have asked the dealership to find out the cost of replacing the rear brake lines. Dealership involved in repairs. Reed Buick GMC 9550 NW Prairie View Rd Kansas City MO 64153 Phone 816-436-6300
