2025 Chevrolet Silverado 1500 Electrical system Problems

“Prior to this incident, I had been having issues with my fuel management system give a “reduced acceleration” warning (codes P0087, P228B) in weather below 28-30F. It was in the shop 3 times prior: first time was “bad fuel”, second had my fuel rail and fuel filter replaced, and third time I had my high pressure fuel pump replaced (also had a rear crank seal leak). …”

“My vehicle frequently loses all cabin sound, including the radio, audible turn signal, and forward/rear collision and lane departure warnings. When this occurs, the cabin is completely silent.

The truck has now been out of service for over 50 cumulative days across these repeated incidents. …”

“Driving 30 mph down a city street when heard a pop and vehicle completely lost power at speed. Engine turned off and I coasted to a stop, which was unfortunately at an intersection and due to traffic could not get over safely. All accessories were still on however I could not restart the vehicle or put the vehicle into neutral, which left me stranded in the middle of a busy intersection. Hazards were working intermittently, at best. Had to call local PD to provide traffic control while we disconnected the battery and reconnected it while standing in an intersection. …”
