What owners wrote
A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.
While the truck was unattended, smoke was observed by a passer-by who called the local fire department. Fire dept broke a window for access, extinguished fire. Hauled vehicle away for safekeeping. Happened while we were at a condo complex, vehicle parked for the evening. Heat intensity and melted plastic indicated that fire occurred in console area. Vehicle was off, we were asleep, nobody had access to interior of vehicle.
My 2018 GMC sierra hd experienced an electrical short or overload, causing a thermal event that melted areas around the rear defrost circuit. Lots of smoke and burning smell, but luckily, I did not see flames. The exact issue is currently being addressed under GM recall# "n192265660 rear window defroster thermal events", however my VIN is not included. The issue I had is exactly what is described and I believe should be included in the recall. I've attached a few images of the burned, melted and broken parts.
My husband was driving our brand new denali which has only 3500 miles on it. The engine completely shut down crossing a highway with 55 miles per hour posting and my daugther of 8 years old was in the back seat. The engine as I said completely shut down with no indicator lights or warning and my husband was unable to steer the vehicle. It stopped off the side of the road by miracle and onstar was called and the vehicle was towed to the closest gmac dealership.
Rear camera only works intermittently and never early mornings when truck is put in reverse. A blue screen comes up with 'service back up camera ' on screen.
