The vehicle has the L87 GM engine. It lost complete power and the engine seized up and would not start again. Fortunately I was able to roll into a neighborhood and get off the main road with no issues. The dealer has confirmed the seized engine and a replacement engine has been ordered with no ETA. There was no prior warning of the failure, besides a shuddering, like I was running out of gas, and then a lose of complete power.

2023 GMC Yukon XL 6.2L V8 experienced progressive engine defects starting in first year. At 7,445 mi (Jan 2023), first dealer visit for engine issues. At 10,315 mi (Apr 2023), Cyl 2 fuel injector failed (internally open), vehicle TOWED to dealer, replaced under warranty. At 14,982 mi (Aug 2023), identical Cyl 7 injector failure (internally open), replaced under warranty. Two identical failures on different cylinders within 15,000 mi indicates systemic defect. By 30,409 mi (Aug 2024), dealer performed engine decarbonization due to carbon buildup from fuel injection issues. Dealer recommended additional decarbs at 38,077 mi and 42,577 mi. At 56,028 mi (Mar 2026), engine suffered catastrophic failure: piston ring failure causing excessive oil consumption and engine destruction, requiring full engine replacement. This matches GM's known 5.3L/6.2L V8 piston ring defect (subject of $150M class action settlement). Defective injectors caused incomplete combustion, carbon buildup on piston rings, ring tension loss, and catastrophic engine failure. Vehicle also has unfixed suspension defect (camber bolt/alignment). Vehicle visited dealer 8+ times. Engine failure poses serious safety risk from sudden power loss at highway speeds. Vehicle available for inspection.

2023 Yukon Denali XL 6.2l: GM oil change recall performed (October 2025) and GMC dealership noted no issues. Prior to recall oil change, at aprox 5k miles interval (45K total miles), check engine oil light on dash and was over 1 quart low. Next oil change at aprox 50K miles, no check engine light came on, but certified mechanic drained and measure oil level, 1.5 quarts low. Engine often sounds odd at cold start, ticking sound. Now an oil change is $100 more, due to special oil, but not compensated for extra cost. Brake calibers failed. February 2026, engine light on, then off, then hood latch dash light warning now on and off. Huge safety concerns with the 2023 GMC Yukon 6.2L.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
