Thanks so much to those who responded.
The problem with my car was a broken park pawl. According to the service manager, that was the root of the entire problem. When that broke it tripped a circuit breaker. They replaced the part and everything seems to be working fine. I am not a mechanically oriented or car person so apologies if I have not explained the problem well.
As for the customer service portion of the event, I was underwhelmed. I was eventually promised a loaner from the local dealership but by then I was already home and when I came back up my car was done. My Chrysler Cares rep seemed unsympathetic and uninterested in my situation. Each time he called I needed to remind him of my case. He never remembered I was no longer in the area. Example: he called to let me know he had secured me a loaner even though I told him I wasn't in the area any more. I asked him if it would be ok if I picked up the loaner when I returned to the area in a couple of days, he said yes but then called me the next day to see if my loaner was ok. He was never rude, I just felt like he didn't care. Also never felt like he was fighting for me to get reimbursed for a rental or other transportation back up to my car. I ended up buying a train ticket since it was cheaper than a one way car rental. I understand he was there to protect Chrysler's interests and not mine, I just wish it wasn't so obvious!
I do have one remaining problem, one of the rear seat theatre screens isn't working. If anyone has any ideas about fixes for that, I'd love to hear them. It's not the contrast.
Thanks again all!
