MEMORANDUM To: National Highway Traffic Safety Administration (NHTSA) Subject: Safety Defect Report – 2019 GMC Yukon Denali 6.2L V8 (L87) with AFM/DFM I am reporting a serious and recurring safety defect involving my 2019 GMC Yukon Denali equipped with the 6.2L V8 L87 engine and GM’s AFM/DFM system. In the past twelve months, I have experienced two separate engine failures, both occurring at highway speeds and both involving valve-train/VLOM failures on the same side of the engine. In each incident, the vehicle suddenly lost power, misfired violently, and became unable to maintain speed. This created an extremely dangerous situation for my family. One failure occurred while my wife was driving; the other occurred while my [XXX] son was driving. Both were forced to maneuver across high-s

Four of the eight oil lifters in my 6.2L engine in my 2019 GMC Yukon failed. The car has around 53,000 miles. The issue was confirmed by an independent service center. There were no warning lamps or messages prior to the issue. Zero. The service center even ran diagnostics with no result and could not confirm the issue until after it partially took apart the engine. I noticed a noise similar to a card flapping in the wind and took it to the service center that same day. The car had been properly serviced with oil changes and still had 44% oil life that same day. Repairs are currently being made and estimated at $4,000.

Driving out a town 400 miles away, with a young passenger in my car on [XXX] in rush hour traffic, i started hearing a slight ticking sound then moved into a full blown knock on my drivers side ( I recorded it). within minutes, my oil light came on and my dash notification reading "engine overheating idle" with the knocking really load. I had to cross 3 lanes to traffic quickly to get to the shoulder of the road, which was NOT a safe place. I smelled smoke and cut the the engine off. I popped the hood to see that there was now no coolant (that is all I knew to look for). I immediately called OnStar Roadside assistance. 2 hours later, I was towed to a local hotel room. Car completely dead. not lights, couldn't lock it, nothing. I had to pay a large fee (almost $2k) to have my car

I just purchased this 2019 GMC yukon denali. About 3 weeks after; the message "service trailer brake system" started beeping...didn't really pay bother me at 1st since I weren't planning to pull anything. Then it started doing it more frequently. Now it is constantly doing it every few days. Can't seem to get it to stop. Very annoying... Any suggestions?

Brake lights completely stopped working. Car is 1 year old.

Steering wheel surges during travel especially when turning at speeds.

2019 GMC yukon denali. 6408 miles. Driving down the highway at normal speed a warning appears that says service power steering. Immediately lost power steering on the vehicle and by the time we got it to the off ramp the steering was completely locked in the straight position. Very fortunate that this did not happen on one of the many curved roads where we live. We had no warning.

Rear shocks are frozen (seized) Makes the vehicle hard to control on bumpy surfaces.

The seatbelt on the second row driver side captain chair no longer works. It started not retracting about a year ago and now it won’t retract or pull out so it is stuck and cannot be used. The $85k Yukon is only five years old, seat belts should last longer than that. GMC wants us to pay $500 to fix a safety concern seat belt. I would understand if the vehicle was 10+ years old but we are still less than 100k miles and we just hit 5 years.
