I heard this was an issue with all Chrysler 200's. It is a costly repair just to have it flushed at $150. Dealer did not give me an estimate, just did the work, then handed me the bill. There was also a ticking noise every time I start the car. It stops when I turn off the heat. They did not fix that, so I asked what it was. They said, "Oh, it's a flap that opens and closes and it's going bad." What?!?! Why didn't they fix it. They checked on an estimate and it will be $129 just for the part. So, another major hit to keep the heat going. Hopefully putting it off doesn't cost me more money!!! I will probably be switching from Chrysler to another major dealer.
