I traded my '06 2500 for an '06 3500 and the new one was turning off the dome lights after like 8 seconds. I told the dealer i wanted it fixed before i took delivery on it. According to what the told me it was a simple flash of the CCM. Computer must have had a virus, lol. Anywho, They got it fixed and i havent seen it again, but only about 5k on the truck since i got it. Hope this helps
