GMC Complaints

I ordered and purchased this vehicle in November of 2021. Since it was new, it has consumed approximately one quart of oil per oil change interval as indicated on the oil life monitor system. Every time I have it serviced by the same dealership, I have inquired as to if this amount of consumption is "normal". They said it wasn't excessive yet to continue monitoring it. This vehicle did pass the recent engine recall inspection yet I'm still feeling as if there may be a problem that hasn't fully surfaced yet based on the initial recall.

On April 20th, 2025 while accelerating from a stop light, my vehicle (2021 GMC Yukon Denali XL, 6.2L V8) started making a ticking noise and the service engine light started flashing. I was within a few minutes of my house and limped my vehicle home. The next morning, I started it and it exhibited the same symptoms. I called my local GMC Dealer, Wright Buick GMC, and was advised to have the vehicle towed to them. It was towed to the dealership and within a few days I was advised that the engine needed replaced. I had heard a story that there was a pending recall, so I had hoped that this would resolve itself without a bill to me. unfortunately I was advised that there was no actual outcome on how to handle recalls, so if I wanted my vehicle back, I would have to pay the $11K for replacement as I was outside of my power train warranty (I had roughly 73,000 miles on my car). I have hoped for some resolution to include my vehicle in this recall but I have not yet received any word from GMC.

On [XXX], my 2022 GMC Yukon Denali XL (VIN [XXX] ) experienced a complete loss of propulsion while I was driving on [XXX] in El Paso, Texas, with my wife and two young children in the vehicle. Mileage was approximately 50,364. While in motion, the vehicle was displaying abnormal behavior, concerned the vehicle would stall on the highway, I exited at the Geronimo exit. As the vehicle slowed, it shut down entirely. Multiple restart attempts failed. The dashboard cycled on and off, displaying a "Service 4WD" warning while the vehicle was in 2WD mode. The transmission locked, and the vehicle became inoperable in the middle of the roadway with traffic passing on both sides. OnStar SOS was activated to communicate the unsafe location. The El Paso Police Department was requested to divert traffic. A city tow vehicle arrived after approximately fifteen minutes; my family was assisted across the roadway. Roadside assistance did not arrive for approximately three hours. This was the second loss-of-propulsion event on this vehicle in less than twelve months. The first occurred in March 2025 and resulted in engine replacement under NHTSA Safety Recall 25V274 (L87 Engine Loss of Propulsion). The [XXX] failure occurred after the recall remedy had been applied and the engine was replaced. The vehicle was towed to the dealer who replaced the throttle body, intake air duct and a service item titled "Repair open ground circuit". I am filing this report to document a second loss-of-propulsion event on a vehicle that already received the remedy under Recall 25V274, and to ensure NHTSA has visibility into the potential pattern of recurring or inadequate remedy on the L87 platform.

Driving back to camper in the late evening and was listening to music and gps was on the screen when I was going approximately 32mph when headliner airbags on both sides went off causing me to hit my brakes and veer into the ditch. I was able to maintain pretty good control but did hit either a rock or stick or something that punctured my wheel sidewall. Unsure if a tree limb then got caught and tore off my bedcover that then left a small dent on the c column on the passenger side. I was able to put my truck in 4wd to get back fully into the roadway and walk about to see potential damage. At that time I only saw my tire was loosing air and bedcover was off aside from the airbag deployment. I slowly made my way home to assess further during complete daylight. I was not injured other than a cut on the hand due to the bedcover and a headache from the deployment. No hard hit or collision and truck did not make contact with tree trunk or any front end damage that would ordinarily come from someone going into the ditch. Reached out to a shop to have them check it out and see if they can see any reason why those airbags would have deployed without force then causing an incident

While passing a vehicle the engine failed and had to replace the engine. The cams and lifters went out.

our truck has the GM 6.2L V8 engine in it. We had the “recall” done where they recommended thicker oil. Despite that recall work we still had catastrophic engine failure and GM’s solution is terrible. A new engine that can have the same issue?

Multiple repairs on brakes and tires are mismatched old since purchased in 2023 tires deflate gas cap missing

driving and truck started to misfire (due to collapsed lifter after shop diagnosis) that then made my truck do reduced steering assist and my wheel got super hard to turn that almost sent me in the ditch at 60MPH and also turned off my Electronic Stability Control and also turned on my Service Parking Brake drove straight to the shop and parked it very lucky i did not crash and the fact that multiple people this has happend too GM need to recall from the 2019 and up for these lifters after reading about it.

My 2022 GMC Sierra 1500 AT4X experienced an engine failure requiring full replacement under warranty. The vehicle was out of service for approximately 46 days. After replacement, the vehicle experienced additional electrical issues and unsafe operating conditions. The replacement engine has now failed again in under 8,000 miles. A dealership performed diagnostic testing (Pico scope) which failed immediately and recommended another full engine replacement. I have been advised not to drive the vehicle due to safety concerns. This appears to be a repeat defect that was not corrected by the initial repair.

Driving down road and had total loss of power steering and yes it is available for inspection. Almost drove it off the road due to loss of steering Yes, it happened to be a failed main grounding strap that created the issue. The dealership made the repair. No, it was inspected and repaired by the dealership Yes, started with loss of power steering, then truck died and these codes popped up: Low fuel code, but tank was full; trailer brake system code; side detection code and esc traction control code.
