STRUCTURE:BODY
Driving down the road at 60 mph, the front upper grill piece just came off, flew up into the windshield and then over the cab of the truck and landed in the street. This is a known defect on these trucks and has happened in 100's of cases. When it happens it makes you react as if you had hit something with the truck, if there had been anyone behind me it could have also caused damage or made them react badly to something flying thru the air. When it happened to me I was prepared for it since I had read online of it happening to so many people. The cause is that its build with really flimsy, very thin tabs that just cant hold up to the wind speed and use needed for being mounted in the front of the vehicle.

On memorial day weekend 2023 my truck ,2021 GMC Sierra AT4 was making a awful noise. I pulled over and vehicle died. had it towed and the warranty covered new engine replacement at 54678 miles(large deposit of metal in the oil pan). June of 2024 again, traveling out of town and pickup making terrible noise and shaking at 76651 miles. Replaced lifters in vehicle. October 11, 2024 took vehicle in for oil change, drove 25 miles and vehicle making terrible noise. Pulled over and pickup died. Had it towed to dealer and they are saying it needs a new engine. ( 87000 miles) they are saying its out of warranty. There seems to be a serious problem with this engine( 6.2) in all the research I am finding. I now have a pickup that I am still making payments on , that I cannot drive.

ELECTRICAL SYSTEM
Rear tailgate would randomly fall down without any key fob buttons being hit. Did some Google searches and it sounds like it is VERY common. There is a faulty tailgate switch that will randomly drop the tailgate which could cause damage if you have a bike rack on or things could fall out of the truck bed while driving if it isn't noticed that the tail gate has dropped

POWER TRAIN
The transmission failed without warning. The truck jerked several times and wouldn't go forward, eventually stopping, putting the driver at risk of being hit or losing control. There were no warning lights or issues prior to this. It was towed to the dealer who knew immediately that the transmission valve body had failed. He said this is a known problem and in fact there was a service bulletin issued last year by GM. As of now he told us there are 2000 vehicles waiting for this part. The part has been redesigned because GM knew it was faulty. Our truck is still at the dealer waiting for the part after a month. Others have been waiting for months. GM is not allocating the part for current customers but instead putting the majority in new vehicles even though they know there are thousands of vehicles less than 3 years old on the road and putting people in danger! The rest of us are left without a vehicle. You are welcome to inspect our truck at the dealership where it currently sits.

STEERING, ELECTRICAL SYSTEM
I am experiencing episodic loss of power steering assist without warning. This lasts for several seconds then power steering is restored. "StabiliTrak” message may be displayed during the event. On one occasion my radio also went off when my power steering failed. On one occasion my vehicle died shortly after losing power steering which almost resulted in me having a motor vehicle accident. I reported the problem to the GMC dealership and have scheduled the next available appointment to have it serviced.

Transmission failed at 75,000 miles, yes it is available for inspection. Truck went into limp mode on the highway and turned into a very dangerous situation, I was barely able to exit the highway. Yes the dealership Martys GMC in Kingston MA has confirmed that it is transmission failure. My vehicle has been sitting on the lot of Marty's GMC since September 13, 2024 waiting for a backordered part to fix the transmission at an estimated cost of $2,500. The warning check engine light followed by every single lamp on the dash appearing on [XXX] which is the date of transmission failure. After careful research of this issue I have found this is a widespread problem with this particular 10 speed GMC transmission in my 2020 GMC Sierra that I am still paying car payments on. I have rented a vehicle at my own cost for the past 4 plus weeks to get back and forth to work. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN, ENGINE, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
At 103,000 my 2020 AT4 5.3L V8 had a P0307 code thrown. Cylinder 7 misfire. Driving highway speeds, sudden loud pop and then the service engine light came on and automatic braking engaged, and the idle got extremely rough. Ended up being a bad lifter, bent rod, tore lobe off of the camshaft. Roughly 8,000 for the repair, new cam, new lifters, spark plugs and coil packs. Now only about 3,000 miles later, driving, sped up to pass on the interstate and another misfire, P0306 this time Cylinder 6. Same symptoms check engine light, automatic braking, rough idle. Seems to be another failed lifter and bent rod. Currently awaiting diagnostic for this second misfire issue. When speaking with the tow truck driver and the mechanic both mentioned a significant rise in cases like this. There is definitely something wrong with the design that the manufacturer needs to be help responsible for. I have less than a month ago replaced all the lifters only to have another one fail again.
