The engine system (6.2L V8 L87) in my 2022 GMC Yukon XL failed due to a known manufacturer defect tied to NHTSA Campaign 25V-274. The vehicle is available for inspection upon request. The issue involves the risk of sudden loss of propulsion, which could result in a crash or injury to myself or others. This is a serious safety concern, and I do not feel safe operating the vehicle in its current condition. The defect has been acknowledged by GMC, but there is no remedy or repair currently available. I have contacted the selling dealership (Rick Hendrick Buick GMC, Duluth, GA) repeatedly for the past three weeks with no returned calls. I also contacted GMC corporate, who confirmed the recall but refused a buyback or replacement because no repair has occurred a” even though a fix does not exist. They offered a loyalty voucher that does not come close to addressing the safety risk or impact. The problem has not yet been inspected by a dealer or manufacturer because there is no repair action to take at this time. No police, insurance, or third-party has reviewed the vehicle. There were no warning lights or messages prior to the issue a” the problem was revealed when I looked up the VIN and learned of the active recall on the engine. I am requesting NHTSAas support to ensure General Motors provides a replacement vehicle and compensation for this ongoing and unresolved safety hazard. I should not be placed in a position where I am expected to continue operating a vehicle with a known and dangerous defect that has no resolution in place.
