NHTSA Complaint #11678448 — 2021 GMC YUKON

While driving the vehicle, the engine started to make a knocking noise and we experienced illumination of the check engine light. We also experienced engine performance issues with hesistation and reduced acceleration. We were able to take the vehicle to a GM dealer and it was determined that the lifters and crankshaft were defective and need to be replaced. There is a warranty out for 2021 GMC Yukon Denali vehicles that were manufactured less than a year after ours that have currently have a recall issued by GM for the same problems that we experienced. My wife and two young children, ages [XXX] and [XXX] , frequently ride in this car and catastrophic engine failures put their safety and livelihood at serious risk.
