One problem related to tank filler pipe and cap has been reported for the 2010 Chrysler 200. The most recently reported issues are listed below.
The power failed. I had filled the tank with gas and was proceeding home in traffic on connecticut avenue in washington, DC. We were stopped due to the traffic lights. The driver of the car beside me to the right motioned for me to open my window. He told me the gas cap was not on and waving at the side. I thanked him and then tried to maneuver the car. The car had no power. I tried moving the gear into low, but that did nothing. The cars beside me and behind me moved on as I sat there. I put the gear in neutral. As the street was on a downhill slant, once the cars were gone, the car could sort of coast and I managed to steer it through force on the steering wheel heading to the curb side where there was a side street. As the car came to a stop just into the side street, a young woman on the sidewalk commented on the gas cap. I asked if she could put it in and said that the power had gone off. We wondered if that would help. She closed the gas cap. I shoved the gear into park and it jerked as I did that. I then tried turning the key to no avail. I took out the key, reinserted and turned it again. I believe it was then that the car started and I was able to turn it around and head to my residence three blocks away.
