One problem related to starter has been reported for the 2012 Dodge Ram 1500. The most recently reported issues are listed below.
With the cold weather, it's not cranking. I had a new battery and starter installed and it still doesn't crank unless it's in neutral and I press the fuel peddle. If it sets for too long in cold, I have to repeat the process and no longer am able to use remote start and sometimes have to be jumped off.
