I took delivery of a 300C on 10/3/04. Thus far the car has met & exceeed my expectations...until yesterday. We were 140 miles from home on a trip when I stopped for gas. Up to that point the car was running perfectly with no indications of a problem. When I tried to restart the car would not turn over. The lights, stereo, instruments, etc. all worked so I knew it was not a battery but it would not turn over at all. After exhausing all of the options in the service manual I contacted roadside assistance which after a 2 hour delay sent a flatbed to take the car to the nearest dealer. The closest dealer was Peters Chrysler in Longview, Texas. The dealer has had very little experience or exposure to the car & actually asked if it was a 2005 "Concorde"...bad sign. After 6 hours of examination they came to the conclusion that the PCM (Powertrain Control module) was defective & was in "shutdown mode". After checking with DC they informed me that a new PCM was on backorder status with DC with no expected date, they told me it could be 2 days, 2 weeks or even longer. They gave me a rental car (they were very accomodating on arranging alternate transportation at DC's expense) and I headed back to Dallas. Bottom line is my car is dead, at a Chrysler dealer 140 miles from my home, with no expected date to be fixed and running again. Has anybody else had any problems with the PCM or it rendering the car inoperable? This all happened on Friday so I haven't had a chance to contact DC yet, but I plan to on Monday.
