Well mine started giving me problems with 40K miles on it, probably because I live in a State the salts the heck out of the roads. I lived with it until the engine blew at 165K miles and I decided to try and fix it while the engine was out. By then you couldn't buy a new TIPM because everyone else had already had problems with theirs and Chrysler was sold out so I had to get a used one. After the second used unit I finally had all my lights working, then my trans problems kept coming on and I sold the truck at a loss.
