One problem related to software has been reported for the 2012 Dodge Ram 1500. The most recently reported issues are listed below.
At about 18000 miles on vehicle it suddenly stalled. Throttle body control light came on, rpm dropped to almost zero. Pumping gas pedal had no effect. Condition lasted about 15 to 25 seconds. Took truck to dealer and was informed it needed a throttle body software update. This was done. Also was performed again later. The stalling is intermittent some times not happening for weeks then again it will happen up to 3 times in a week. Bit once stalled on my lady as she was crossing an intersection . Vehicle now has 77000 miles on odometer . I thought this just a hassle until about three weeks ago. As I was merging on to the interstate at about 65 mph in front of a big truck the vehicle stalled for a long period. The big rig was within a very few feet of my vehicle before engine started running again. Needless to say this scared me big time. This was when I started to look for someone to be in my corner on this vehicle has been serviced by Dodge dealership regularly since new. Each time I have reported stalls and at one time had a case opened with Chrysler. I am told they find nothing and they only have my word this is happening. This from dealer and Chrysler.
