2019 Buick Envision

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

At highway speeds steering became unstable and unresponsive with various pavement conditions(almost a feeling of becoming airborne), Even at low speeds (over a speedbump) vibration occured. Dealer repair consisted of replacement steering gear with new motor and internal power steering control module. 4 wheel alignment performed after parts replacement and a test drive. This was a serious safety condition to us and others. No inspections were done by others prior to this event occuring in May of 2026. There were no messages of impending failure.

HVAC CASE DOOR MELTED. GM case #9-10542006159. Repaired 2 years ago under warranty and GM knew there was a problem with the design. The air distribution system is placed to close to the heating coils and it keeps melting. It has failed again and GM will not do anything about it and keeps saying its out of warranty. They did not repair the problem correctly when it was in warranty. They tell me there is not a fix for it and there has not been a recall. I'm afraid the car will catch on fire
