2023 GMC Yukon XL: excessive oil consumption

Filed Sep 23, 2026 · Engine · CA

This is an ongoing problem from date of purchase, before the normal oil change time the low oil light comes on. When i check the oil dip stick it is in fact low. I have to add at least 2 qts of oil to get it to the right level. Time frame would be at least once every 2 months under normal CA driving conditions. Also does have a rough idle and noise that sounds like the motor is going to come apart on startup. I have takin it to the dealer, they performed consumption test and checked the motor recall. The dealer told us that our motor passed the recall inspection, made the changes, oil, oil cap, etc. Then told us it passed the consumption test. Since then I still have to add oil between oil changes. We were told by the service tech that even if the motor is bad, there is no replacements at this time and the vehicle would just sit at our dealership until we can get a replacement. No one has been hurt at this time. I'm just waiting for the motor to lock up. The vehicle can be inspected upon request. The only warning light that comes on is the low engine oil warning.

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.

Vehicle "Low Oil Warning" light appeared at approximately 3000 miles after an oil change. Checked the oil and it was nearly 3 quarts low. Without any visible leaks or loss of oil, I called local GMC service department and had them inspect. They found that 4 pistons and other components needed replaced due to failure. There was no signs or symptoms other than the warning light. The car has been in the shop for 3 weeks. I currently do not have my vehicle, but I was going to use this vehicle for a long road trip and I'm sure this would have been a catastrophic loss, and possibly a safety issue for my family traveling 1k miles at highway speeds.

The engine failed at highway speeds on approx. July 15 2024. Filed a claim with GM. GM replaced minimal engine parts to get the car running. GM refused to acknowledge this was a safety issue. Engine failed at highway speeds again approx 09/20/2024 this time just shutting off. When the engine oil was drained at the dealer it was silver. The entire engine was replaced this time. Again GM refused to acknowledge this was a safety hazard. After engine replacement the low oil light came on at the time of an oil change. I am monitoring oil burn on this new engine.
