TL* THE CONTACT OWNS A 2010 GMC SIERRA 1500. THE CONTACT STATED THAT WHEN THE PISTONS WERE LOOSE AND STRUCK THE CYLINDER WALL, IT WOULD LOOSEN UP THE ENGINE AND CAUSED AN ABNORMAL KNOCKING FROM THE ENGINE. THE DEALER WAS NOTIFIED OF THE FAILURE WHO ADVISED THE CONTACT THAT THE FAILURE WAS NOTHING TO BE CONCERNED ABOUT AND WAS NOT HURTING THE ENGINE. THE MANUFACTURER WAS NOTIFIED WHO STATED TO THE CONTACT THAT THEY WOULD SPEAK WITH THE DEALER TO DETERMINE THE REMEDY FOR THE FAILURE. THERE WERE NO RECALLS FOR THE FAILURE. THE FAILURE MILEAGE WAS 5,000 AND THE CURRENT MILEAGE WAS 24,000. UPDATED 01/10/12*LJ
