It started with an alternator the day I bought the truck. The alternator got replaced but the purchase was too recent for the warranty to cover it. They handed me a bill for 1200.00. They eventually stated it was covered. Started experiencing brake noises. Took it in. They said everything looks fine. 11 days later experienced a catastrophic brake failure and all needed to be replaced. Not covered under warranty due to normal wear and tear. Radio turned itself up and down by itself and went blank. They say it needed an update. Eventually replaced under warranty 3 appointments later. Made another appointment for brake noise. Before the week out appointment comes around experience a massive loss of power and truck sounds terrible. Dropped 2 lifters and cam shaft was grooved. Replaced all for 10k. Didn’t even make it to the first oil change after the repair and the truck is stuck in park and none of the exterior light or horn works. Tailgate will not drop. Appointment for truck was Saturday. It is now Tuesday and truck has still not been seen. DONT BUY THIS TRUCK. They look good and have great interiors. They aren’t worth a crap.

I bought a 2019 GMC 1500 Sierra with 10 miles on it and have had to replace the transmission twice with less than 90k on it. GMC would not do anything about it knowing that there are 1000's of lawsuits have already been filed against. GMC wants to nickel and dime you by saying you need to flush your transmission fluid, then they want to replace other components, all knowing that in the end it's your transmission that needs to be replaced. I wish I would have done my research.

Bought this new & paid cash for it. Had I know of all the problems with these trucks I would have went to Chevy instead This has to be the worst truck I’ve ever owned GMC ought to be ashamed of themselves They don’t care or want to fix anything “ie” brakes, engine, transmission and other issues SO MUCH FOR GMC BEING A STEP AHEAD
