Thanks all. I just saw these replies but took the vehicle into Dealer as it's still under warranty. It was throwing one of the "lost communication with..." codes and also a bad bank in the Cat. They are replacing the cat and failed the battery and replaced that as well."
This is all good info. to have though because it won't be under warranty forever. Thanks again
