First cold snap today. Start my 2013 Ram 2500 this afternoon hear a strange groaning/ wining noise
. Stop the engine look under hood nothing seems out of place. Re start and I get the Low Batt CEL sure enough it's not charging only showing 11 volts
. Drive a short bit and the groaning noise comes back and so does the Volts back up to 14. Engine running normal everything else normal after a short while the groaning stops. Let the truck sit an hour start it and again Not charging again
. I pulled code U059F any ideas? I can't find the code on our lists. I'm guessing I'll be paying my dealer a visit after my shift tomorrow. I'm wondering how much warranty I've got left....... 63875 miles on the clock....
