ELECTRICAL SYSTEM, ENGINE
While driving 75 on the highway the vehicle shut off completely, shifted to neutral and a message flashed on the dashboard to "press start again". This has happened previously when my 16 y/o was driving but we chalked it up to user error. Scheduled appointment with dealership. There were no warning lamps, no lights illuminated on the dashboard. The vehicle just cut off and I have not been able to reproduce the issue.

ENGINE
The engine on my vehicle has been consuming approximately a quart of oil every thousand miles for months. I have made this issue known to the dealership who services my vehicle over that time period. The dealership (Radley Chevrolet in Fredericksburg, Virginia) and particularly the management has not been concerned about my issue. I have also contacted GMC. I've explained to Radley Chevrolet and GMC that as a [XXX] while in the military [XXX] that my vehicle will leave me and my family stranded somewhere without recourse. Both are aware of the ongoing issues and have not addressed my many documented concerns. I have an extended warranty, so I'm covered for parts and labor for years. Again, the concern is for my safety and the safety of my family. This vehicle could possibly leave me as [XXX] and my family on the side of the road. I have reported these concerns numerous times.

ENGINE
The vehicle’s air suspension system failed multiple times, followed by failures in the rod and/or crankshaft engine components. Currently, the vehicle is also experiencing engine warning lights and reduced propulsion issues. The vehicle is currently at the dealership and is available for inspection upon request. The loss of propulsion and engine failures create a serious safety hazard on the road, as the vehicle can unexpectedly lose speed or stop functioning, increasing the risk of rear-end collisions or being stranded in dangerous traffic situations. The dealership has explicitly stated that the vehicle is not safe to drive due to the risk of potential accidents. Yes, the dealership has confirmed the air suspension failure and the engine component damage. However, they have not yet been able to identify the exact cause of the current reduced propulsion issue despite multiple service attempts. The vehicle has been inspected multiple times by the dealership’s service department. Prior to the failures, engine warning lights and other dashboard warning signals appeared. These warning indicators first appeared after the air suspension failure and before the reduced propulsion issue emerged. These issues closely match the conditions described in the recent GMC recall; however, our specific vehicle model was not included in the recall. We believe this might be a systemic issue and request that NHTSA investigate whether the recall scope should be expanded.

ENGINE
I took my vehicle into the GMC dealer near my home in Beaver Dam, Wisconsin (Napleton) on April 30, 2025 to have the L87 engine recall addressed. I had a video with sound where a loud clacking noise could be clearly heard, coming from the passenger side of the engine. The service attendant and the mechanic assigned to my vehicle listened to it and both agreed that the sound was not normal, or good. Four hours later, they called and said the vehicle was ready to be picked up. They did neither pass or fail the engine, and didn't put in thicker oil. I was told that they aren't doing anything until they received clearer direction from GM. This is very disappointing for me and now afraid to drive on the highway for fear of catstrophic failure and potential crash. I called another GMC dealer nearby, in Watertown, WI, who said they weren't doing anything either with the L87 engines (year 2021-2024) until they recieve clearer direction from GM. I have taken my vehicle in 2 previous times to address the "clacking" noise, each time they say they hear nothing wrong.

POWER TRAIN
Driving at normal speed when my 2021 Yukon backfired and began to lose power. The check engine light came on. The vehicle would go into reverse and would not get over 20 miles an hour. It has been at a GM repair shop since March 24th waiting on the tranmission valve body. There is no ETA from General Motors on when this part will be available. Could this be associated with the most recent GMC recall of 2021-2024 Cadillac, Chevrolet and GMC vehicles?

ENGINE, POWER TRAIN, FUEL/PROPULSION SYSTEM
My engine failed while I was driving & I had no warning. It was very scary & dangerous. Luckily I was in an area where I could get off the road quickly. It started skipping then lost power. I basically coasted off the road & had to call for help. It was making a bad knocking noise. This happened 2 weeks ago on April 16. It has been sitting at Glynn Smith.GMC dealership since. I was told by the service manager that the engine failed & I will need a new engine. the engines are on back order now. I fear they will replace it with the same problem. I see the recall this week but will changing the oil viscosity really fix it?? Doubtful. Someone is going to get killed or hurt from this problem. I do not want the same issue to happen with a new engine.

POWER TRAIN
I have had major transmission failure in my 2021 GMC Yukon Denali (6.2L V8, 10-speed automatic). The vehicle has approximately 72,000 miles. Recently, a critical internal clip/retainer in the transmission broke loose, sending metal debris throughout the transmission. This catastrophic failure has rendered the vehicle undrivable and requires a complete transmission replacement. Unfortunately, the vehicle is just outside the powertrain warranty, yet I firmly believe this failure is due to a manufacturing/design defect – not normal wear and tear. I purchased this Yukon Denali as a premium, flagship SUV and have maintained it carefully. I expected the transmission to last well beyond 72k miles under normal use. It is disappointing and that a core component failed so early. Not only has this imposed a significant financial burden, but it also undermines my confidence in the vehicle’s safety and reliability for my family. A modern transmission should not self-destruct at this mileage, especially given GM’s reputation and the Denali’s top-of-the-line status. Importantly, I have discovered multiple known issues and GM bulletins related to the 10-speed automatic transmission used in my Yukon. For example, GM issued a major recall in late 2024 (NHTSA Campaign 24V797000, GM recall #N242454440) affecting 2021 Yukon models (among others) due to a defective transmission control valve that could fail and cause the rear wheels to lock up, this demonstrates that GM has acknowledged serious problems in the 10L80/MQC 10-speed transmission design. Additionally, a recent GM service bulletin (PIP6008C, Jan 24 2025) indicates that internal transmission retaining rings can dislodge, causing the internal gears to separate – which leads to loss of reverse and internal damage. This scenario is similar to what happened in my transmission. My family was left stranded away from home with no warning. The vehicle just stopped working. The warning lamp did not come on until diagnostics was run.

ENGINE, POWER TRAIN
On March 28, my 2023 Yukon Denali stalled on a 4 lane road forcing me to make an emergency stop on the side of the road in a right hand turn lane. The vehicle required towing to a local GMC dealership. They could not restart the vehicle and upon evaluation found metal shavings in the oil. They have recommended an engine replacement. There was no warning, it just stalled and would not restart. My Yukon remains at the dealership and we are still waiting for an engine.
