NHTSA Complaint #11680893 — 2021 GMC YUKON XL

Complete engine failure and lock up driving 70MPH. I was very lucky to not wreck the vehicle when this occurred with my family of 5 present. Had towed to the dealership and diagnostics performed. Diagnostics confirmed crankshaft issue and complete engine failure requiring engine replacement. I was informed that this was the same issue that is under current recall, but the 5.3L is not part of it. This is the same crankshaft issue that has been recalled in over 700K 6.2L GM motors. I am being told that the 5.3L engine is not covered under the recall and i am 100% responsible for all costs related. I want this 5.3L issue reported and documented to help extend the recall to the 5.3L engines in the future
