My 2022 GMC Yukon XL with the 6.2L L87 engine was previously subject to NHTSA Recall 25V-274 / GM Recall N252494000 for L87 engine loss of propulsion.

Prior to this failure, the vehicle had already failed the GM PICO test related to the known L87 engine issue, and the recommended corrective action was changing the oil to 0W-40 synthetic and replacing the oil cap. Despite that intervention, the engine still failed at approximately 49,000 miles. A sudden complete engine stall without warning while driving created a dangerous situation, particularly with children in the vehicle. This raises concern that the prior corrective action did not resolve the underlying defect..
