2022 GMC SIERRA 1500 Complaints

In August 2023, while driving on the interstate during rush hour, a critical engine component fell out of my vehicle, leaving me stranded in a dangerous situation. The car was towed to the dealership, where I was informed that a piston had fallen off the engine, requiring a full engine replacement. Now, in January 2025, my vehicle has once again failed—this time shutting off completely while I was driving on the Selmon Expressway, putting my safety at risk. After being towed to the dealership, I have now been informed that the engine has seized and will not turn, requiring yet another full engine replacement. This is completely unacceptable. As a loyal GMC owner, I have never experienced such catastrophic failures, let alone twice within such a short period. Engine replacements should not be a recurring issue, and I am deeply frustrated by the lack of reliability and the significant financial and safety concerns this has caused.

Radio software glitch (bulletin 23-NA-183) cuts blower fan speed to 50% or below resulting in ineffective defrost during winter months. GM knows of the issue and has a radio software update but will not complete this as warranty and/or recall and will demand you pay for the correction. Due to the uncontrolled and loss of power to fan that cannot be corrected by the owner (ex. turning radio off/on will not fix it) this has become a serious safety concern as the windshield can fog, frost, or freeze while driving the vehicle.

At approximately 18,000 miles the engine on my brand new GMC seized up while I was taking 4 of my employees Downtown Detroit. The engine stopped as I was merging into 3 lanes of traffic from the left lane. I had to cross 3 lanes during rush hour almost resulting in a major accident. Then I had to wait 2 months to replace the engine. 25,000 miles later, the second engine seized up while I was transporting my father between nursing home facilities. The third engine, I have recently been told only has a 12,000 mile warranty. I have requested that GM give me a 60,000 mile warranty on this 3rd engine and they refuse as it is past 30 days since the 3rd engine was installed. I should be getting a new truck, but I am just asking for a warranty. This is a known problem, which obviously has not been fixed. In both instances, there were no indications of a problem until the engine stopped running. The first time, I had 4 of my employees, which I was responsible for, in my car merging in the left lane with no engine power during rush hour, putting everyone at great risk, including other cars and people. The 2nd time, I had my [XXX] father in transit between nursing home facilities. This obviously was a very stressful event for both of us. Both of the dealerships that replaced the engines confirmed that they have been seeing this same issue in many other GM trucks. I personally know of 3 people that this has happened to. In both cases, I had to wait weeks to replace the engine because of the backlog to order the engine for other people.

The system that failed was the wire harness for the internal brake control. This is a well documented problem on YouTube and Reddit. I was driving home from the mountains, with my 7K lb camper, and I started receiving incessant messages alternating between "Trailer Brakes Disconnected" and "Trailer Brakes Connected". The messages made it impossible to see the speedometer and hear music or calls. Most importantly, I lost my trailer brakes in the mountains of North Carolina. Meaning the only way I could slow down was with my truck brakes, while a 7,000 lb camper was pushing me. I took my truck to the dealership today and paid $166 for a diagnostic. The stated the issue was with my camper. I tried to explain that many owners were having this problem and it is well documented. They stated there was no recall on my vehicle and gave me a print out of what to check on my camper. I checked my camper and there are no issues and no issues when i connect it to my other vehicle.

Engine Mileage is 72,728, on my 2022 GMC Sierra 1500 AT4, L87 V8 Engine. While driving [XXX] to drop off a co-worker at a Toyota dealership, my engine started making a strange "clicking" sound. A Toyota tech came out to look at it quick and suggested I try to get to a GMC dealer about .5 miles down the road. I made it about 100 yards before the entire truck shut down. The dash went black and then engine stopped running. Had to get towed to the dealership. Engine is considered "dead" by Diamond Auto in Worcester, MA, and the cost to replace the L87 V8 Engine is quoted at roughly $11,717.89. There have been zero prior engine issues on this vehicle. The engine failure came out of no where. Thank you for your time- [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have a 2022 GMC Sierra 1500 AT4 with a 6.2 engine. The truck had roughly 50,000 miles on it when the engine completely stopped working while I was driving on a busy multi lane highway during rush hour. After almost getting hit by multiple vehicles while trying to glide my truck to the side of the highway. I waited 2 hours trying to get my truck towed to a local dealership and the next day was told that my engine completely seized up and my engine needed to be replaced. I waited two months without my truck while it was at the dealership waiting on an engine that was back ordered. They told me it was complete engine failure. They couldn’t figure out why, all fluids were good yet the engine failed.

I was driving my vehicle when is started making a loud noise coming from the engine . My vehicle turned off in the middle of road and didn't start again. Putting the safety of the other drivers and my ownsafety at risk.

I currently own a 2022 GMC Sierra with 75823 miles on the vehicle. I purchased the vehicle new from Bill Cramer GMC, and just learned today that the engine has to be rebuilt due to bad lifters, cam shaft damage, and excessive oil consumption. According to the dealership and further research, this is a common issue with the GM 5.3L engine that is currently in my truck. Because the truck is now out of warranty GM will not cover the costly repair. Something has to be done regarding these engines, due to the thousands of people this has affected. According to the sites, no recall has been issued for these engines and its very dangerous to operate because the engine can lock up while driving.

On or around January 27 2025 my 2022 sierra loss power and shut down at night and dropped to 0 rpm. I was close to the house and got pulled home by relative. When I did get it cranked lifters were tapping which was common in the 6.2 but I drained my oil and filter and saw the glitter look. Truck was still tapping after warmed up. Last night I about got hit at an intersection when same thing happened. I felt a jar, and truck went to zero rpm and loss power. Truck said, put in neutral and try again. When I pushed starter had a click. Then I pushed start again and it started smoking. It burnt my starter up, because engine is seized. I saw where there is an investigation on this and I really hope it goes through because that was a scary moment and it is safety concern. Twice the same thing. But now can’t turn crankshaft, nothing to drive, making payments on a 80,000 truck that is my personal and work vehicle. 92000 miles on my truck and have my oil changed regularly. I’m stuck between rock and hard place, but will be getting it towed to a dealer somewhere. To here I need a 6.2l engine in my sierra slt. 2 year old truck it is stressful. I know im going to here 10,000 $$$ I don’t have.
