I also have a 2007.5 and it came with a built in exhaust brake system. Are you using the tow mode? Thats when it kicks in. IMHO take in tto the dealer and have it checked to see IF you have one already. If so have it checked. If everything is OK then read your owners manual. This might save you some money for more camping.
