First happened at 75000 with engine and electrical system shut down. Doors don't work and radio/bluetooth works when it wants too. Exposed wires got fixed because of moisture. Steering power failure at low speed and emergency maneuvers. The dealerships cant fix it although they know its the steering pump. At 93000 a systemic failure of electrical systems again. New dealer fixed supposedly the wires again, still exposed. The car electrical does not perform over 76 degrees outside temperature. Power steering is a problem and getting worse. Finding that there are more problems with power steering from 2013 and lower models.
