NHTSA Complaint #11658403 — 2021 GMC YUKON

The vehicle’s air suspension system failed multiple times, followed by failures in the rod and/or crankshaft engine components. Currently, the vehicle is also experiencing engine warning lights and reduced propulsion issues. The vehicle is currently at the dealership and is available for inspection upon request. The loss of propulsion and engine failures create a serious safety hazard on the road, as the vehicle can unexpectedly lose speed or stop functioning, increasing the risk of rear-end collisions or being stranded in dangerous traffic situations. The dealership has explicitly stated that the vehicle is not safe to drive due to the risk of potential accidents. Yes, the dealership has confirmed the air suspension failure and the engine component damage. However, they have not yet been able to identify the exact cause of the current reduced propulsion issue despite multiple service attempts. The vehicle has been inspected multiple times by the dealership’s service department. Prior to the failures, engine warning lights and other dashboard warning signals appeared. These warning indicators first appeared after the air suspension failure and before the reduced propulsion issue emerged. These issues closely match the conditions described in the recent GMC recall; however, our specific vehicle model was not included in the recall. We believe this might be a systemic issue and request that NHTSA investigate whether the recall scope should be expanded.
