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.

On XXX we were in the acceleration lane on XXX, merging onto the highway. When we engaged the cruise control the car rapidly accelerated up to 97 mph. We were unable to get car to slow down, or disengage the cruise for approximately 1 minute. The care ran for 97 mph for the minute or so this happened. Husband was driving and he did all we knew to do to disengage the cruise and get the car slowed down. After approximately 1 minute the car started to slow down. We immediately took the car to Kelly Chevrolet in [XXX]. We were told that General Motors usually doesn't do anything to help the consumer unless there have been 4 reported cases. (This happened one other time about 2 weeks prior, but we thought it was a fluke and didn't report it.) We had this car for 1 1/2 years with 22,000 miles. The warranty would repair, but I refused to drive it again, under the circumstances. We have since traded the car ini on another car as we couldn't drive it.

I was driving ~72 MPH on the interstate and my car suddenly downshifted and the dash read “Speed limited to 62 MPH”. I took the nearest off ramp and the brakes completely failed. The dash initially read “service transmission” and “service breaks”. After restarting the Buick Envision, the MyBuick App diagnostics stated “service breaks” only. The car was towed to the dealership this date. I have not heard from them on what has caused the brake failure yet.

On [XXX], I started the car. Very loud, cracking noise came from radio. Turned off radio, noise stopped. When I used turn signal, noise came from turn lever. Turned off signal, noise stopped. Put car in park and pushed ignition button to turn off. Noise came thru ignition button. Later restarted the car, noise was gone. Concerned there is a power surge going thru system. Saw same problem for others online at [XXX] . Stated there that replacing amplifier corrects problem. Both dealer and corporate Buick are aware of problem. However, both are refusing to replace part, as car isn't making noise currently. One person on the forum stated he was unable to turn car off when problem occurred on his car.
