One problem related to gas recirculation valve (egr valve) has been reported for the 2009 Dodge Ram 1500. The most recently reported issues are listed below.
The total integrated power module failed and it's a common problem in all Chrysler and Dodge vehicles. That fails the engine runs rough, ac, brake light, turn signal, horn, wipers, stop working and transmission stays in 1st gear. The lights on the das stay brakes, abs, seatbelt, check engine light and air bag. . . This is an specially when the module fails while driving in the road. Dealers know it's a common problem but they rather have customer pay for a new tipm.
