Most recently, passenger side automatic door stopped mid-way, I closed it manually, drove a couple of feet and turned off the car. Then the car would not start. Door is not working automatically only manually. Started easiy with jumper cables but continues to not start on its own most of the time, usually when engine is cold it won't start on its won. This happened about 8 months ago and dealer said it needed a starter even though I showed printout from tow truck showing it wasn't the starter. This also happened some time before that and dealer said I needed a new battery and that seemed to fix the problem temporarily. This has been a problem since I first purchased the car and the dealer did not fix the problem.
