This vehicle has now experienced two catastrophic powertrain failures at very low mileage.  The first catastrophic engine failure occurred at approximately 23,696 miles. The vehicle was taken to a GMC dealer, where the repair documentation states that the engine had suffered significant internal damage, including damage to the #3 connecting rod, a missing connecting-rod bearing, bearing material throughout the engine, and a scored crankshaft. The dealer determined that the engine was seized and required replacement.  GM replaced the engine under warranty with GM engine assembly part number 12740076.  The vehicle has now experienced a second catastrophic failure. On [XXX], while traveling approximately 40 mph,  experienced grinding, lurching, and knocking, followed by a complete loss of propulsion. The truck would no longer move and had to be towed to a GMC dealer. At the time of the incident, no warning lights or warning messages were observed.  The transmission is also suspected to have failed, although the exact cause and extent of the transmission failure have not yet been determined by the dealer. I understand that NHTSA is currently investigating failures involving GM 6.2L L87 engines, including failures occurring after previous recall remedies and engine replacements. I am therefore requesting that this incident be included in NHTSA\u2019s investigation and considered when evaluating the effectiveness of the existing recall remedy and the safety of replacement L87 engines.
