I was driving ~72 MPH on the interstate and my car suddenly downshifted and the dash read âSpeed limited to 62 MPHâ. I took the nearest off ramp and the brakes completely failed. The dash initially read âservice transmissionâ and âservice breaksâ. After restarting the Buick Envision, the MyBuick App diagnostics stated âservice breaksâ 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.

BUICK ENVISION 2025 ELECTRICAL SYSTEM

While driving the dash and radio randomly turn off. Sometimes staying black for minutes others until you stop the car and walk away for several minutes. Leaving you without a way to tell how fast you are going, or any other safety information, fuel level or more.

While driving for approximately 2 1/2 hours  with cruise set at 78. I did need to brake on occasion and then resume speed. For no apparent reason the car suddenly braked. Speed dropped to about 50 and then immediately resumed speed. No one was hurt. Things in the back seat pushed forward.  I donât know if it has anything to do with that incident but from them until I returned home, about 1 hour later my windows were fogging,  I turned on the defrost about 3 times.

My 2025 Buick Envision with 10,000 miles on it has squeaky brakes. My previous 2023 Envision had the same problem,  Brakes check out ok, but squeak persists.
