2019 GMC Yukon Xl

The contact owns a 2019 GMC Yukon XL. The contact stated that while driving approximately 68 MPH, the vehicle vibrated abnormally, with a knocking sound coming from the engine compartment, with the check engine warning light was illuminated. The vehicle was taken to a certified mechanic, who diagnosed the vehicle and determined that lifter #7 had failed and needed to be replaced. The contact stated that all the lifters were replaced. The contact stated that approximately 5 days later, on October 2, 2025, while reversing, there was a burning odor with black smoke coming from the exhaust pipe. The vehicle was towed to the mechanic and was diagnosed with coolant intrusion into the engine. The contact was informed that the engine needed to be replaced; however, the warranty only provided the replacement of 2 head gaskets. After 7 days of having the vehicle, while driving approximately 68 MPH, the vehicle started shaking with the check engine warning light illuminated. The vehicle was also idling roughly. The vehicle was towed to the mechanic and was diagnosed with fuel pump failure. The fuel pump was replaced; however, the vehicle was idling roughly, and there was an intermittent misfire in cylinders #1 and #6. The dealer was unable to identify which cylinders needed to be replaced. The contact discovered information of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling); however, the VIN was not available. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 127,000.

The vehicle experienced a lifter and valve train failure within the warranty period, as addressed in GM TSM MC-10209953. This failure can cause sudden engine noise, loss of power, and potential engine seizure while driving, creating a serious safety hazard for the driver, passengers, and others on the road. The component failure is reproducible and has been confirmed by a repair shop; it is available for inspection upon request. An engine rebuild was completed just after the warranty expired, and the manufacturer has denied warranty coverage and refused to address the issue. Prior to failure, no warning lights or messages indicated a problem, meaning drivers have little to no warning before a potentially catastrophic malfunction. Because this is a documented issue affecting multiple vehicles and the manufacturer is refusing corrective action, this defect presents a clear risk to public safety. I urge NHTSA to investigate this matter, determine whether a safety recall is warranted, and require the manufacturer to address this known defect to prevent accidents and injuries.

The V8 engine on our family's 2019 GMC Yukon Denali XL check engine light came on and began ticking while taking our daughter to college in Montana. The dealer informs us the engine has probable lifter failure and will need to be disassembled to diagnose additional issues. The estimated repair costs are from $3,000 to $10,000+, may require a new engine, and we will be without the vehicle for almost two months. We are incurring additional costs such as lodging, airfare to fly home, costs for an additional car, and storage for a travel trailer that must remain behind. The warranty on our vehcle expired last year. The vehicle has been consistantly serviced at our local dealer. Research and discussions with other GM customers inform us this is a known issue for our year and that a recall was issued for vehicles for 2021 to 2025.

2019 GMC Yukon XL. Purchased pre-owned from a dealership in July 2023. This month, August 2025, my transmission has failed. Apparently this defect is notorious for this particular year of GMC Yukon XL. There was a lawsuit against GMC but it was closed in June 2025. The issue is real and widespread and GMC should ABSOLUTELY be responsible. There’s no reason a six year old vehicle should require this extensive repair.

Engine Knock, possible piston rods bent. oil in cylinder. cylinder has not enough compression. No safety issues, was able to drive to mechanic without harming myself or others. this is the second vehicle in my family to have lifter or rods issues leading to major engine work. Check engine light came on after the vehicle began to misfire.

Driving down the interstate and engine gave out, started shaking, and started losing speed. No warning, in the middle of the night with two young kids in the car. Sat on the side of the highway in the pitch dark. 2 days later truck was towed but the GMC had no one to look at it. Had it towed again and that GMC dealership said it was the engine and they see it all the time with that year/make/model. $16,000 for new engine. Contacted GMC and they stated that year is not included in the recall. Research this issue on google and most owners of the same year/make/model have the same issue with no help to solve the problem.
