One problem related to lose power steering has been reported for the 2003 Dodge Ram 1500. The most recently reported issues are listed below.
All of a sudden the truck started shutting off, whether in idle or on the freeway. It would happen multiple times during the day. When shutting off, the truck would loose power steering and brakes. Took to multiple dealerships and mechanics who couldn't find anything wrong with the truck, would never throw any codes, finally spoke with a mechanic who talked to a computer person who stated that we needed to have the computer fixed but it wouldn't be available for 3-6 weeks due to it being on national back order. This needs to be recalled, due to safety issues. You are unable to control the vehicle when you lose power steering and brakes. National back order tells me that there is a problem and Dodge knows about it.
