good morning, sir. same thing happened to me on my 2020 gmc Sierra. try disconnecting the battery. I kept getting the same codes and warnings so i gave up on it. I just left the battery disconnected overnight and truck was back to normal in the morning. I did change the brake pads to early so I had to have the dealership reset my brake pad life.

My lifters also went out, they were replaced. Dealer ship diagnosed my truck, it was the transmission and a bad motor mount. Mi getting a renewed transmission 3yrs/36000-mile warranty whichever comes first, I'm also having the driver side motor mount replaced. good thing ill only be paying my deductible.

it's an 8 speed. The dealer diagnosed it the transmission is bad, and the driver side engine mount is screwed. Honestly it doesn't make sense to me since the truck only has 94,700miles on it. I'm really hoping the extended warranty I bought thru CarMax will cover it. (Fidelity Warranty)

Good morning every one. So i have a 2020 Gmc Sierra 1500 elevation crew cab 5.3. Every time i accelerate the truck jerks, i also got a random misfire but that went away, the check engine light has not come on since. The dealer did replace the throttle body and a coil when my lifters went out that might be the issue but I'm really not sure. Has anyone had the same issues? my truck has 94369 miles

So, my truck has been making a squeaking noise on the passenger side front wheel. It happens when the truck is moving and its more noticeable when turning the wheel right while the truck is moving. I'm thinking it's the wheel hub. I did replace the front brake pads thinking that was the issue but it's not. What do yawl think it is please advise? It's a 2020 Gmc Sierra 1500 Elevation on a 3'' lift
