Reported risk: On certain vehicles, the valve train adjustment screw lock nuts may not have been tightened to proper specification during assembly. Over time, the screw lock nut could unthread and separate from the adjustment screw, causing damage to the engine, resulting in a loss of motive power which could increase the risk of a crash causing injury and/or property damage. Correction: Dealers will check the torque of the valve train adjustment screw lock nuts and ensure the nuts are tightened to the proper torque specification. If the nut is missing, the engine will be replaced.
