2025 Buick Envision Electrical System Problems

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. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.
