Just bought a 2010 Ram 3500 Crew. The check engine light came on at 600kms. Turns out when hooked to the computer that the EGR was said to be leaking. WTF? The dealer tried to get it to leak on the hoist, now way. With the check engine light on the command start wouldn't work, and when the engine was cold it ran like the old cat engine in a dozer! Rough. Now when the truck is at idle and stopped at a light the mirrors rattle. I can hear them from inside the cab with the windows up! Not impressed so far.
