NHTSA Complaint #11703083 — 2022 GMC YUKON

My 2022 GMC Yukon with the 6.2L V8 engine is covered under recall 25V274000 for connecting rod and crankshaft defects that can cause engine failure. Approximately three months ago, Wiesner GMC dealership performed the recall inspection and stated the vehicle passed. Recently, the engine suddenly began misfiring on cylinder 6. The failure was sudden and severe—the vehicle started shaking significantly, the check engine light illuminated, and multiple safety sensors began deactivating. The vehicle was clearly unsafe to drive. An independent repair shop diagnosed oil leaking into the cylinder and stated the condition is consistent with internal engine component failure—the same type of defect the recall is meant to address. When I contacted the dealership to have it re-evaluated, they stated my vehicle is no longer under standard warranty and I would be responsible for repairs. After escalating to GM customer service, they confirmed extended coverage exists under Special Coverage N252494003 (10 years/150,000 miles) if the diagnostic confirms the issue is related to the recall defect. The fact that my vehicle passed the recall inspection three months ago and is now exhibiting the exact failure symptoms the recall was designed to prevent raises concerns that the inspection procedure may not be detecting all affected engines. The component (engine) is available for inspection. This defect poses a serious safety risk as the sudden loss of power and deactivation of safety systems could cause a crash.
