2019 Buick Envision problems

Filed Jul 15, 2026 · Brakes · AR

Driving home from work and I seen the "service brake assist" light popped on. I did not know what that meant, until I tried to slow down around a curve. The brake pedal was extremely firm and mad stopping in time almost impossible. I made it home and looked on internet for answers. I checked the sensors, brake fluid and checked again and no help. I noticed a puddle of oil under the car and checked the lipstick which showed i was very low on oil. The next day I had to tow the car 45 to 50 miles to dealership. The dealership had car for 3 days and told us it was the brake vacuum pump that failed. The vehicle was not under warranty and we paid over $800 to have it repaired. We live off a busy road and it was very hazardous driving it home.

The turbo failed by reducing speed all a sudden when I was driving on the freeway. Got the problem repaired and not even a month later same thing is happening again.

The envision started losing power, the engine would not gain speed or if it did it was very slow, had the booster vacuum sensor changed, Sudden loss of power or sluggish acceleration, In the beginning the noise/whining was not loud however increased from the engine. Took to a repair shop, could not figure it out, informed dealership, was advised to bring it in. As the car was driven into the lot it died and was unable to start again, dealership informed it was going to cost more than the $22,000 that I paid for it. It appears that the turbo’s failure has damaged internal components, a full engine rebuild is necessary. Bought the car with 63,000 miles, engine went around 100k, had an easy care insurance/mechanical policy just over the mileage limit, tried contacting Buick, due to no recall they wouldn't start a case file for me

I have a warning on my dash, "Service Brake Assist" that comes on and off, but will not stay on. The dealer says they can't identify the problem unless it stays on and then bring it in. I did some research and find a class action complaint suit in 4 different states, of several GM cars manufactured between 2017 - 2020. Mine is a 2019 Buick Envision. The class action suit identifies the "Brake Vacuum Pump" defect. The defect will be known, when you step on the brake, the pump fails by exploding, and you have little or no brake whatsoever. More than likely causing a car crash and potentially loss of life. So what am I to do ? Wait for the pump failure and CRASH! Please look into this situation and potiential save lives.

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.
