Just bought a 2024 Denali HD and it has the 120v outlet in the bed. No power. Tried it several ways, truck off, in accessory mode, running and even tried with the cargo/bed lights on and nothing. Look in the owner's manual and it says a "DC/AC switch" has to be turned on. Okay, where is that? Manual shows it as a button on the dash with the tailgate open, exhaust brake, etc. There is no button there. Any help out there ..read more

Recently bought a 2024 Sierra Denali HD. It has a 120v outlet in the bed, but I have no power. I have tried several things, engine off, accessory mode and running.

Manual shows a button on the same bank as the exhaust brake, tailgate open, etc and there is no button there. Any help out there ..read more

Hi All, New to the board as I am looking purchasing a new 1500 Diesel. I swore off GM after two bad Chevy's (one Brake Failure not fixed by GM and the other was bad Transmission at 60k miles) and said I wouldn't come back. Have been a Ram guy since. I want a LD Diesel as my final truck before retirement for the increased mileage as we travel. As I am sure everyone knows Ram's fuel pump issue with theirs so that is not an option. I have a friend who has a friend that has the GMC version... Read more ..read more

2019 Sierra Denali. 80-90% of the time when I turn it off it starts dinging and gives a “shift to park” message. No rhyme or reason when it happens or doesn’t happen. Engine shuts down, but radio continues to play and dash is lit up. Dealership wasn’t sure how to correct it. I think this is a known GMC issue? Open to ideas/suggestions ..read more
