While driving the vehicle on a roadtrip in Missouri, the engine lost power and had a flashing check engine light. Upon diagnosis by three different technicians, the 6.2L Engine needs replaced after only 123000 miles. The lifters and camshaft have failed. This is a known safety issue and numerous recalls have been implemented, but my high end Denali is mysteriously absent from the recall. This is unsafe and unsatisfactory.

Vehicle is equipped with the 6.2L L87 V8 engine. Prior to receiving the dealer service for Recall 25V-274, the vehicle experienced a distinct highway vibration, powertrain shudder, and fluctuating/jumping RPMs on the highway. The dealer subsequently performed the recall remedy by updating the vehicle to the thicker 0W-40 oil specification. However, the underlying transmission torque converter had already suffered catastrophic failure due to the powertrain stress/shudder and…

2022 GMC Yukon XL suffered catastrophic transmission failure at approximately 87,000 miles. An ASE-certified transmission repair facility determined that the torque converter failed, resulting in transmission damage requiring over $7,000 in repairs. GM declined any assistance solely because the repair was performed by an independent ASE-certified facility. I am concerned that a major transmission component failure at this mileage may represent a broader defect, particularly…
