Vehicle is a 2022 GMC Yukon Denali with the 6.2L L87 V8, covered by the federal safety agency Recall 25V‑274 (GM N252494001). The recall remedy was performed. The engine passed the dealer inspection and was given the higher-viscosity 0W-40 oil remedy rather than an engine replacement. On 05/26/2026, at approximately 43,000 miles, the vehicle suffered a sudden engine knock while being driven by my wife. At the same time, the dash displayed Service ESC and Service Traction Control warnings, the vehicle's speed fluctuated on its own without driver input, and the air suspension cycled up and down while the vehicle was in motion. The vehicle had to be towed to the dealer. The dealer diagnosed a failed lifter with resulting camshaft damage and repaired it under the powertrain warranty. The vehicle was out of service approximately fifteen days. Shortly after the vehicle was returned, it began displaying a "Theft Attempted" message on the dash every day. I reported this to the dealer in writing on 06/15/2026 with a photograph at 43,898 miles. The dealer stated it was unlikely to be related and did not scan or diagnose it. On 07/14/2026, approximately 560 miles after the repair, the vehicle became inoperable and had to be towed to the dealer a second time. It is currently at the dealer and has not yet been diagnosed. The unexpected loss of power, speed fluctuation, and stability-control failure at road speed present a serious crash risk. This vehicle passed the 25V‑274 inspection remedy and then experienced a valvetrain failure regardless, which is directly relevant to Recall Query RQ26001 into the adequacy of that remedy.

with no warning ,the GMC 6.2L engine failed on my family trip to Colorado. The engine seized at HWY speeds, stopped running, failed to restart and had to be towed to local dealer. This issue is a known GMC defect with numerous reports and a safety recall issue. I was fortunate to be able to move offer in hwy traffic and get to the shoulder where my situation took 8 hours travel time to continue my family trip.

We were driving on 95S when the Yukon Denali automatically shifted itself from D to N. On the dash it had a warning message to press start again. When my husband did that we could smell a smoke smell. Meanwhile, we are in the middle lane of the highway while trying to safely get off the middle of the interstate without being rear ended by the semi that was behind us. We finally made it to the side of the interstate where my husband was able to put the Yukon in park. He was never able to get the vehicle back in Drive. The car would never click back over to start up again. We had to have the vehicle towed to the nearest GMC dealership where it has now been for almost 3 weeks with no timeline for a date of a new engine. I was told it needed a new engine and radiator. Said the alternator was trying to catch fire when he was trying to start the vehicle. This is the SECOND time the Yukon has been in the dealership in 4 months for this recall issue. This time it is 2hrs away from my home.
