My 2008 Chrysler T&C has been in the shop four times in 1.5 months for the same problem. The car keeps going into limp/fail safe mode. The transmission is fine, but it won't shift when in the mode. The code is always the same and indicates power failure/low power to TCM. They have changed the TCM and checked electrical lines and it keeps happening. I'm very frustrated. I have two young kids and this car is to cart them around and it is unreliable and can't be fixed. Chrysler keeps telling them to do random things and it keeps reoccurring. The only common denominator there might be is cold and wet weather conditions. Any thoughts?
