2022 GMC SIERRA 1500 Complaints

The motor stoped working 6.2. Left me stranded in the middle of the road. No warning, the engine just gave up and stopped working. As well as the grill flying away and breaking my windshield, this happened last year in february while driving 75 mph.

Tailgate opens randomly on numerous occasions. Sometimes it won't open after pressing the button.

The truck was a part of the L87 recall inlcuding the 6.2L engines. It passed their pico inspection. They changed the oil. I was driving down the interstate in Memphis rush hour traffic with my daughter in the backseat and suddenly lost all propulsion. The dash said please start truck. I lost all power to the engine. I had to navigate high speed traffic and merge lanes safely. The cars stuck behind me, myself and family, and others nearby could've been in a wreck because of this issue. We were stuck on the side of the interstate waiting for a tow truck. It was towed to the nearby dealer where it sat waiting for the engine to be replaced for a couple of months. We are extremely lucky that the large trucks did not run us over. GM has since replaced the engine with another remanufactured engine that is already making noises similar to the one it had before. What is going to happen when we are in an accident due to GM's negligence and continued issues with this engine?

The coolant control valve failed. This is a known failure point of poor design and on every other truck from 2019-2023 with the duramx LM2/LZ0 engine, they are covered by a special service warranty to 150,000 miles. GM knows this items fails and puts consumers lives at risk when the failure throws the truck into limp mode on the freeway. They refuse to do a recall to avoid doing the right thing. This is deceptive and wrong.

The front upper grille molding/deflector located above the front grille and directly below the hood on my 2022 GMC Sierra 1500 has become loose and is separating from the vehicle. The left side attachment points appear to have failed, allowing the plastic component to visibly move and lift while driving at highway speeds. The condition worsens with airflow, and the part vibrates and flexes significantly while traveling on the freeway. This creates a safety concern because the component appears at risk of detaching completely from the vehicle and becoming roadway debris, potentially striking other vehicles or causing drivers to take evasive action. No warning lights or dashboard messages were present prior to discovering the issue. The problem was first noticed after observing movement of the grille trim while driving at normal highway speeds. The vehicle has not been involved in any collision or modification that would cause this condition. A GMC dealer inspected the concern and confirmed the vehicle is not currently included in an active recall despite an existing GMC recall addressing grille deflector detachment on similar 2022 Sierra 1500 vehicles. The defective component is currently still installed on the vehicle and available for inspection upon request. Due to the risk of detachment while driving, vehicle operation at highway speeds now presents a potential hazard to surrounding traffic.

On 2/23/26 my GMC sierra 1500 AT4 3.0L Inline-6 Turbo-Diesel, it auto stopped (which I will never keep on again) on an incline and would not start back up or shift gears and rolled a few feet. I had to turn it off and restart it, then the engine light came on and a notification about conditions not favorable for shifting? My app said service was needed for engine/transmission issue. I took it to the dealership and it now has to have the transmission control valve body assembly replaced. I did not receive a recall notice for my truck but, it seems to be the same issue that the recall was for on GM vehicles of the same time period. Of course the dealership said they have no loaner vehicles and I'm supposed to be without my truck for approx. a week and a half at this point. I am disappointed with GMC and the quality that I am paying $70k for. I had a 07' Silverado 2500 I purchased new and drove it for almost 15yrs. w/ no issues. Hopefully this is a good fix and it'll last but, from what I've seen, GM is not the quality it used to be. This is on top of being in the shop for a coolant control valve issue that wasn't recalled either but, a known issue on the pickups so beware. I did call GMC and they will reimburse up to $44 a day on a rental (has to be a GM vehicle btw) during this fiasco of course afterwards and with a bunch of paperwork but, I have to have a vehicle, in TX nothing is close by. Good luck everyone!

Following engine replacement per NHTSA for 6.2l GMC engine. I am submitting a safety complaint regarding my 2022 GMC Sierra 1500 Denali (refresh body style). The vehicle has experienced repeated failures of driver-assist features and safety system warnings, including: Dash messages: “Lane Keeping Assist System Unavailable” and “Service Safety Restraint System.” When the fault occurs, driver-assist features including Adaptive Cruise Control become inoperative. The issue has recurred multiple times, including after repairs. After one event, the truck sat parked approximately 10 days and the battery discharged to failure and required replacement. A dealership visit documented DTC U3000 (“Internal Electronic Failure”) in the front view camera module. The dealer replaced/programmed/calibrated the front camera on 02/09/2026 at approximately 58,405 miles (invoice/RO #285795). The symptoms have recurred despite prior resets and this repair. I am concerned about loss of driver-assist functions while driving and the presence of a safety restraint system warning. Please investigate whether there is a defect related to the front camera/driver-assist systems and/or electrical module behavior that can cause repeat faults and battery drain on this model.

Front grill deflector detached from vehicle when traveling on highway. This is a recall repair for the same issue. There were no warning lamps.
