      U0001 Code, What the H!!!!!

      Hello all, I am Harry from Oley Pa. 50 miles N.W. of Philadelphia. My 2013 limited has a recurring problem. All the interior lights, check engine, battery, low tire pressure etc. etc begin to flash off and on eventually car stalls and won't run correctly.

      First time it happened I was close enough to coast into a garage. The mechanic checked it out. He told me my battery polarity had reversed. So he put in a new battery, Wala problem solved. Not. Every few months it happens again. When it does I disconnect the battery charge it then it works again. Now on my third event with the new battery even after disconnecting and recharging again, this time it didn't work.

      Always the same code, U0001 non communicating bus.

      Anyone ever hear of such a thing? I'd hate to go to the dealer for a diagnosis of an electrical issue. TERRIFYING!!!!
