general problems of the 2021 Chevrolet Silverado 1500

While towing at night with horses, trailer lights started blinking on and off, eventually for longer periods, then stopped working all together. Research shows this is a common problem in gm vehicles related to the wiring and trailer light module. This is especially dangerous when pulling horses at night and all of the sudden lights go out. Gm issued a technical service bulletin. This should be a recall. . .

Rain is coming in through the back window. Dealer is stating that the rain is coming from the sliding window but satellite is stating it’s the brake light on the top of the truck.

Rear third brake light is leaking water into the cab and causing water stains on the headliner. I am worried about it eventually causing an electrical short or more water damage. I don't have a rear window that slides open and the rear glass has never been replaced nor has the third brake light all original from factory.

Transmission lags between 1st & 2nd gear some times as long as 3 seconds making transfer case hit hard . I have had this truck at the dealer 2 are 3 times with this and other matters , the maintenance technician reports he can not reduplicate my grievance , this malfunction occurs more prominently in cold weather in morning on first take off . All so turn signal malfunction at random no particular pattern , tech. All so unable to reduplicate .

I just bought my new silverado yesterday, and when I drove it for the first time at night I realized that the infotainment display stays extremely bright even when the instrument cluster is dim. This is dangerously distracting while driving at night. The model I have does not givee an option to adjust the infotainment screen separately.
