I purchased this vehicle as a GM Certified Pre-Owned vehicle. At approximately 7,000 miles, the engine developed a knocking noise and was determined to require complete replacement. I brought the vehicle to the dealership on May 19, 2025, and it remained there until September 17, 2025—nearly four months—while the replacement engine was obtained and installed. Since receiving the replacement engine, I have driven approximately 6,000 miles. On August 4, 2026, I was informed by the dealership that the replacement engine has also failed and requires another complete engine replacement. This means my vehicle has now experienced two major engine failures at extremely low mileage, including failure of the replacement engine. I understand that the 6.2L L87 engine has been subject to a GM recall involving potential engine failure and loss of propulsion. I have now learned that NHTSA has escalated its investigation into continued failures involving these engines, including failures occurring after the recall remedy. My experience appears directly relevant to that investigation. I regularly transport my children in this vehicle and am extremely concerned about the possibility of an engine failure occurring while traveling at highway speeds or with my family in the vehicle. I feel fortunate that the previous failures did not occur under those circumstances. I have contacted GM and requested that they repurchase or replace my vehicle. GM denied my request and has refused to provide me with a reason for the denial. I am asking NHTSA to document my complaint and investigate whether the existing recall remedy is adequately addressing the underlying safety defect, particularly given that my replacement engine failed after only approximately 6,000 miles.I can provide repair orders, recall documentation, mileage records, and correspondence with GMC","products":[{"type":"Vehicle","productYear":"2021","productMake":"GMC","productModel":"YUKON","manufacturer":"General Motors, LLC"}]}]}
