So get this...I believe my issue is fixed.....with a new battery...no joke. I had the dealership look out over and everything checked out. It would appear a sensor or module doesn't work well if the voltage is low....which it would be slightly low due to the cold weather, plus lights, defroster, seat warmers, and high blower setting.
Before I took it to the dealership and after I tried a few things, the jeep wouldn't even budge an inch.
Even though it sounded like something mechanical broke (clunking/slipping sound) everything drives just fine now.....put 600 miles on it yesterday without a hitch.
