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.

When the car is in auto engine shut off mode, when the brake is released the steering power assist message displays, the steering wheel locks up, the doors unlock and the interior and exterior lights flash. The car will start back up but it takes a second to start. The car is also starting to not start back up and completely shut off at the light. All of the lights will start flashing. This is highly dangerous as the steering wheel lock almost caused my family to get into a major car accident. The car will be taken to a dealership later this week.

The first time (Dec 27, 2019) my family was driving on regular roads when it suddenly said engine overheating. We pulled over & looked at the engine and could see coolant fluid squirting out of the coolant pipe-there were tiny holes in the metal pipe allowing this leakage of fluid. We were away from home and had to wait several days for a replacement part to be ordered & repairs to be done. ( it cost us thousands between the work, oem Buick parts, and extra hotel days since we were on vacation away from home.) they replaced the coolant pipe. Now again (April 23, 2021), after driving about 2 miles on a regular road, approaching the entrance to a highway, the car suddenly said engine overheating! I stopped and turned the car off. I waited about 25 minutes till it cooled. Then I started to drive again, very slowly & with no air conditioner running. Within about 3 minutes, the temp was going up so I pulled over and waited again. This happened one more time as I made it home. Now I can't even drive it without it quickly showing the engine overheating. A professional mechanic replaced the thermostat & new dexcool (orange) coolant but it's still overheating. I have been very careful with maintaining my car, replacing and changing fluids in accordance with specs. My car is essentially paralyzed & I'm afraid to drive it anywhere! certainly not what I expected from a luxury vehicle such as this poor quality!! please note, I have to find my poetical receipts but providing the most recent receipt. Original issue mileage was about 58,000

Twice in the last month, I have been driving in motion less than 5 mph, and the car accelerated by itself. I had to slam on the brakes to stop it. The tires screeched. Very scary as it accelerated fast, lurching forward. Both times in a cat lot.

"auto stop" function would not restart in traffic - stopped at signal light; had to push vehicle into a parking lot. Wouldn't restart for over 20 minutes. Two additional electrical issues (we believe are releated) previously that have not been fixed.

Dash lights go out when you are in a shady area. Stay out way to long. No way to adjust to make them bright. Collision alert goes off when you are not near hitting anything. Clock went from est to West coast time. Car makes a knocking sound in the rear end. Also makes a scrapping sound. Doesn't matter if your going up hill, downhill, left or right. Never know when it will do it. Always when the speed is between 45 & 55 mph. This is the second Buick Envision that was repurchased. Same issue with the first one. Worked on many times by garage & even a rep sent from Buick. The problem could not be fixed. This was 18 months of issues to get a resolution. Happy that I have a Chevy equinox now.

Car makes a scrapping sound. Spent 32 days, then 22 days at the garage. At the 32 days torque tube to drive shaft changed. Noise came back. At 22 days Buick sent a field rep. To work on Envision. Invoice said they loosened & retorque the frame that attaches the rear differential to the unit body of the car. With my case Buick called & told me the garage changed a carrier bearing. Asked the garage why they said that. Was told they had to put something down to get paid. Buick ended up doing a repurchase. Now we have the same noise in the replacement Buick Envision 2017. Another issue with this SUV is the dash lights. It's sunny out & you get in a shaded area & they go out. Dash is so dim sometimes you can't see your speed or your gages plus radio. There is a wheel to brighten or dim the lights. You roll the wheel up to have a bright setting & it rolls back, like it's spring loaded. July 14, 2017 was the first trip of many to the garage. The noise is sporadic. It doesn't matter if you are going uphill, down hill, left or right. The garage know how to make the noise. They drive 50 -55 mph & drop the car in low. This puts the car in 6th gear. We don't do that. It makes the noise. Was shocked that they figured our how to make the scrapping sound.

There is a problem with the exhaust system or maybe not, with a horrendous groaning rattle that occurs within specific parameters. At about 45-50mph, if cruising with almost no acceleration, when you do accelerate, you get an awful rattle that sounds as though it is coming from the exhaust system. It is startling and in of itself doesn't seem to be a safety item except it startles you. Dealer indicated when brought in that road salt, small stones, etc. Had settled on top of the fuel tank and caused this god awful sound. They said they blew it out and the problem did appear to be fixed - except it took only a week for it to return. If what the dealer said was true, there is a gap between the fuel tank and body that allows normal road debris (salt, pebbles, etc.) settle up there and cause this condition to occur. Not a safety issue except it is distracting and startling when it occurs. Could be a safety issue if other things get up there, like a rag or cloth, and it rides against the exhaust system, while lodged above the fuel tank, and catches fire. That as not happened, but imagine it is possible given the circumstances.
