Due to the severity of the issue, the vehicle was towed to a GMC dealership for diagnosis.  The dealership diagnosed lifter failure and a cracked cylinder head. The dealership also documented coolant intrusion, oil/coolant contamination, and evidence of internal engine damage. Repairs were attempted, including replacement of the cylinder head and lifter.  After the repairs were completed, the vehicle never left the dealership because it continued misfiring on the same cylinder. GM later determined the engine had a failed piston ring and scored engine block requiring complete engine replacement.  The vehicle has approximately 55,000 miles, has been properly maintained, and was purchased new. This catastrophic engine failure resulted in loss of power and major internal engine damage at relatively low mileage.  I also opened a case directly with GM Customer Assistance regarding this failure. The case involved multiple escalations after the initial repair attempt failed and the vehicle ultimately required full engine replacement. GM ultimately advised that only partial assistance toward the engine replacement would be provided, leaving the customer responsible for a significant portion of the repair cost.  I am submitting this complaint because this vehicle appears consistent with the ongoing NHTSA investigation involving GM 6.2L L87 engine failures and loss of motive power.","products":[{"type":"Vehicle","productYear":"2019","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]}]}
