From reading the various responses, I'm beginning to see that this is not a common issue, unfortunate as it is for me. I think I will call over to the dealer and talk to their maintenance folks to see if they have any ideas. However, I must say that I have wanted this car ever since I first heard about it.

And it has not been a disappointment.

Sure my experience caused some alarm, but I love my Challenger. That may mean I am hopeless, clueless, etc., but I can't imagine parting with it now. I hope that some of you prospective buyers won't be put off by my personal tale of woe; that was not my intention. I was just hoping for an easy answer, i.e., "oh, that's just your [insert unintelligible gearhead language here]!"

I could've bought a BMW. But, to me, that is a car that says "Hey! You cut me off or ding my door then I'm going to pop out of my car and sue you!" The Challenger says "Hey! I might just have a chainsaw in my trunk and I'm not afraid to use it." I had to go for the chainsaw.

Thanks again for the comments and I look forward to your advice.
