general problems of the 2008 Dodge Caravan

Tipm has failed stuck in limp mode. Caused engine light fuel issues and stalling.

At about 140,000. Check engine light came on then off and on again. Replaced gas cap. Engine light still came off and on, one or other for extend time. Returned and after a check they said I needed to get it back when light was on. Fianlly last March at 153,000. I returned and they informed me it was my convertor. I feel that the convertor failed prematurely and after complaints did not get me any where with Dodge I am complaining that the part, which had not been damaged, fail prematurely and that it is a deective part.
