Yukon would not idle without turning off on its own. Check engine light came on. Took it to my mechanic. Check engine light was flashing which indicated an active misfire. A running compression test found little to no compression from cylinder 6. Further investigation found that cylinder 5 had been repaired in 2022. Mechanic recommends engine replacement.

My wife drives this vehicle to work, it has started to experience reduced engine power driving on the highway causing her to pull to the side of the road due to no throttle to maneuver the vehicle in and out of traffic, leaving her on the side of the busy highway, we have now parked the vehicle after investigating problem there is a knocking noise coming from the lower part of the engine, after research of this 6.2l engine there are reports of the crankshaft and connecting rods seizing up and coming through the side of the engine block, knowing this we are hesitant to continue driving the vehicle. We continue to make payments on a vehicle that we can't use and can't afford to make a engine replacement at the moment. Very frustrating to say the least, as expensive as these vehicles are we have lost faith in the gm name.

Vehicle shudders at acceleration at times making merging onto highways and passing vehicles dangerous.

Incident: January 7, 2026 · Filed: July 6, 2026

The vehicle experienced a sudden and rapid mechanical failure of the 6-speed automatic transmission (6L80 model) within a span of less than two weeks. The light did not come on until the transmission was past salvage. The failure escalated rapidly from initial minor slipping to a severe loss of vehicle propulsion. A loss of acceleration while driving poses an immediate crash hazard, as the vehicle cannot safely maintain speed with surrounding traffic or accelerate out of dangerous situations. The failure required towing and a complete out-of-pocket replacement of the transmission unit at 116,374 miles to restore safe operation. The manufacturer has failed to issue a safety recall despite widespread failures of this component causing unexpected power loss on public roadways.

I was driving home on the interstate from vacation and I was set on cruise control it was 1 am so not a lot of traffic was on the road thank god. It could have been really terrible if lots of traffic was present as the engine just died without notice! The vehicle was decelerating nothing was working I could not speed up. I was able to get over to the side of the road. I got a notification on my phone that said battery critically low start vehicle to charge battery. Well nothing would start at this point. I lot all power seconds later. I thought that the cruise control was locked up and restarting it would reset it. I called roadside assistance to get a jump and that did not work. I got towed into an auto repair shop. They called me and told me that the engine is locked up that they drained the oil and found metal in it and metal pieces in the oil filter as well. They checked for leaks and said there was none that they could find. They said there was a recall but it was for the exact same symptoms that was diagnosed here but only starting with year 2021. Mine is a 2019 Yukon Denali with low mileage so not sure if all the other Yukons were aged out or already past engine death and that’s why they were not part of this but this should be included in with the open recall considering how everything is the same that is effecting this year that I have and they should pay for a new engine! Clearly the v8 6.2 gmc engines are having major issues I’m just glad I wasn’t going that fast and traffic was slow so I was able to get over safely before catastrophic things happened since there was no warning when this all happened!

Getting the valve ticking noise.

Incident: March 1, 2026 · Filed: May 28, 2026

The contact owns a 2019 GMC Yukon. The contact stated that after starting and exiting the vehicle to allow it to warm up, the contact later noticed that the vehicle had turned off. The vehicle was towed to a first mechanic, who was unable to restart the vehicle or determine the cause of the failure. The vehicle was towed to a second mechanic, where it was diagnosed and determined that the engine had failed and needed to be replaced. The vehicle was not repaired due to the cost. The dealer was contacted and provided an estimate for the repair, but the vehicle was not diagnosed or repaired. The contact stated that the dealer's estimate was higher than the mechanic's estimate. The manufacturer was notified of the failure and suggested purchasing a new vehicle. The failure mileage was approximately 170,000.

Complete engine failure. The dealership kept the engine. This happened at a low rate of speed but it would have been much worse if on the highway. Yes the engine was completely replaced. The check engine light came on and their was a loud ticking noise coming from the engine.
