Vehicle is a 2022 GMC Yukon Denali with the 6.2L L87 V8, covered by NHTSA 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.

ENGINE AND ENGINE COOLING — Filed 06/19/2026

The contact owns a 2022 Chevrolet Yukon. The contact stated that while driving at an undisclosed speed, an abnormal knocking and ticking sound emanated from the engine before the vehicle stalled. The vehicle was towed to a local dealer, where it was diagnosed with total engine failure, requiring replacement. The vehicle was not yet repaired. The contact stated that the current engine was a replacement engine from a previous failure, which was tested prior to installation but also failed. Additionally, the contact stated after the failure, the transmission could not be shifted into Neutral, forcing the tow operator to drag the vehicle onto the flatbed truck. The manufacturer was not yet notified of the latest failure. The failure mileage was 45,000.

ENGINE — Filed 05/18/2025

My 2022 GMC Yukon (6.2L L87 V8, VIN [XXX]) is covered by recall 25V-274 / GM N252494000, "L87 Engine Loss of Propulsion." In May 2025, at about 65,800 miles, the engine lost power and shut down while I was driving, then developed a loud knocking noise and an intermittent low-oil-pressure warning. The dealer (The Faricy Boys Automotive, Salida, CO) found excessive metal in the oil sample and replaced the entire engine under this recall in June 2025. The original engine serial was [XXX]; the replacement serial is [XXX]. On XXX, at about 93,000 miles — roughly 27,000 miles after the recall repair — the REPLACEMENT engine GM installed began making the same knocking noise. A dealer (Turner Automotive, Montrose, CO) has confirmed the engine is failing and has ordered a second replacement engine. The recall remedy GM performed did not fix the defect; the engine GM installed to cure the recall is now exhibiting the same failure mode (knocking / loss of propulsion). When the engine failed on XXX, GM Roadside Assistance refused to cover towing despite the engine's replacement coverage, and I had to pay roughly $484 out of pocket to tow the vehicle about 74 miles to the nearest dealer. This is a safety issue: the defect causes loss of motive power, and in my first failure the vehicle shut down while I was driving. I am reporting this because the recall remedy itself appears defective, consistent with NHTSA Recall Query RQ26001 regarding the adequacy of the remedy for campaign 25V-274. Please associate this report with that recall and that investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN,ENGINE — Filed 06/17/2026

With no warning, my engine 6.2 L stopped running at highway speeds and failed to restart. The power train completely failed for a second time after having a previous engine replaced for the same failure in 2024. I had the car inspected per the recall along with changes in the oil viscosity as recommended along with service inspection. The car left me stranded again on rural highway for over 5 hours in temps that exceeded 98 degrees. The car would not start and went into a power save shutdown and had to be towed to the dealer. I was fortunate to have avoided any traffic on the highway enough to get the car off the road. This is not safe to drive on the highway and GMC has known defect and safety concern with this issue.
