Consumer Description

I was driving 55 mph and the engine failed without any prior warning. I was partially blocking traffic while waiting for a tow truck. The car was taken to a repair facility and diagnosed. Spun rod bearings on cylinders 1 and 2 damaged the crankshaft. I purchased this car $49,000 45 days ago and have made one payment on a car that is not drivable and parts are not readily available. There is a GM service bulletin because this is a known issue but not a recall. The power train warranty is up by mileage not time. I contacted the dealership and GMC and they will not assist with repairs.
