    There exist a defect which is common through multiple years with RAM that have the Cummins 6.7L diesel engine. The problem is the heater bolt in intake system. When this fails it falls into intake and proceeds into piston which requires engine rebuild. Unfortunately the same part is put back in causing repeat. Solution Banks Monster Ram Intake system. Many, many owners over years have experienced loss of vehicle in both new and older models. Engine lock up can cause loss of steering and worse on highways.
