Buick Envision Engine problems by year

I was going to work in the morning. I went to stop at the redlight right at my work but my brakes were very firm and wouldnt push down. My service brake warning came up on my dash and service engine light came on. I had to practically stand up and press as hard as I could to get it to slow down enough to not rear end the person in front of me. I thank God I wasnt going very fast and thankfully the light was turning green at the same time so I just slowly rolled thru and pulled it into my work parking lot. I had...

The contact owns a 2020 Buick Envision. The contact stated that while driving 35 MPH, the low oil pressure warning light was illuminated. The contact inspected the vehicle and became aware that the oil level was two quarts low and the oil level was topped off. The failure was a persistent issue. The dealer was contacted by phone and made aware of the failure. The vehicle was taken to the dealer. The contact was informed that the oil level was two quarts low and oil was added. The contact was informed that an oil...

At 1,578 miles, my 2025 Buick Envision would not start in my garage and had to be towed to the dealer. The check-engine light was on. The dealer tore down the engine and found a spun No. 1 main bearing. GM replaced the complete engine under warranty. The vehicle remained at the dealership from November 10, 2025, through January 6, 2026, totaling 57 days. A similar engine failure while driving could cause an unexpected loss of power. I do not have the failed engine; its current location is unknown.

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...

Same as in the other two complaints. At one year and approximately 5000 miles I personally did the first oil change. Car was approximately 3 quarts low on oil after draining the oil for the oil change. Filled up to manufacturers recommendation. Two months later and approximately 1000 miles on the car, the car was 1 quart low. GM has a bulletin on this very issue bulletin number 01-0 6-0 1-011N. Started oil consumption test through the dealer. Dealer stated the first remedy is replacement of a valve, followed by another consumption test. Next option is replacing the engine.

Description of Safety Defect: While operating the vehicle at approximately 25-30MPH and make a right turn, the vehicle experienced a sudden and total loss of power/engine stall, accompanied by a "Check Engine" light and a "Reduced Engine Power" notification. This resulted in a near-collision on a public roadway. The vehicle's steering and braking response were significantly compromised during this event, creating an immediate life-safety hazard for the driver and passengers. Dealer/Manufacturer Response: The...

While driving in traffic, after changing lanes, the vehicle experienced a complete electrical shutdown without warning. The engine shut off, the dashboard went completely black, and hazard lights were not functional. There were no warning lights, messages, or audible alerts prior to the failure. The vehicle was in active traffic and, stopped without power steering or brake assist. After opening the hood, multiple wiring harnesses and a loose battery cable were visually observed. When wiring was physically moved,...

Fuel pump and fuel control module failed. Car will not stay running. Currently at GM dealership. Confirmed and repair cost about $500. No warning lights.

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.

The contact's friend owns a 2017 Buick Envision. The contact stated that while driving at approximately 45 MPH, the engine warning light illuminated. The vehicle was taken to an independent mechanic, who determined that the failure was due to the sensor for the catalytic converter. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted. The failure mileage was approximately 179,000.

The vehicle was taken in for the oil level not registering on the dip stick 5235 miles on the odometer, they said it was 2 quart oils low. They said they would do an oil consumption test and to bringv it back in 2000 miles. We took it back with an odometer reading of 7451 and it was again 2 quarts oils low. There is an oil consumption issue on this vehicle.

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.

My vehicle only has 81824 miles on it and I am having head gasket issues. I have a coolant leak into my engine. It is barely 7 years old. This should NOT be an issue in a vehicle this age with this many miles. I have seen that this has become a known issue with the 2018 Buick Envision and it should be a recall. I have had to refill my coolant reservoir 3 times since my oil change. A compression test has been run on my coolant system and there are no other leaks. Thus it is the head gasket.

Prior to the first oil change which is recommended at 7500 miles, I check the oil and there was NO oil present on the dip stick...none, not a drop. I had to add 1 3/4 quarts to get it in the accepted range. We took the car for its normal 7500 mile oil change and informed the dealer, upon inspection and oil change they said nothing was wrong with the car. About 2000k miles after that oil change I checked the oil again and again it was well over a quart and 1/2 low. I added enough oil to get the oil level into...
