Car started on the evening of August 12th, driven approximately 17 miles, stopped for 10 mins, restarted & driven 5 more miles. I went to start it again after about a half hour, would turnover but would not start. Car towed by mechanic 8/13/2014. As of 9/26/14, car has been in mechanic's care & unable to fix. Car being towed back to me with no further information on how to fix it. Mechanic has had vehicle on 2 separate diagnostic machines. Mechanic informed me he thought it was the computer then flywheel then back to computer but unable to fix it & giving up trying. This car is in good shape with low miles on it, I'm at a loss as to what to do or how to get it fixed. It was with mechanic 6 weeks & now being returned as "unfixable".
Tl contact owns a 1999 Chrysler 300m. During an oil change, the mechanic noticed that the tread for the drain plug was wearing thin and the oil pan and plug needed to be replaced. Chrysler is aware of the failure and stated that it only occurs with the 300m and concorde vehicles. The tool that mechanics use to perform the oil changes is the cause of the failure because it damages the tread. Chrysler stated that she would have to pay $575 plus tax for the replacement. The contact informed them to tape the pan and plug instead. She filed a complaint with the manufacturer. The current and failure mileages were 94,815. Updated 12/12/2007 updated 12/12/07

1. Normal everyday driving. 2. Radiator/condenser cooling fan burnt up; could smell electrical components and saw smoke coming from fan unit. Blew 30a fuse and smoke/smell stopped.

Luckily the car kept running on one of the two fans, and it was at night when it wasn't so hot! Had to replace dual cooling fan unit. 3. Replaced dual cooling fan unit and 30a fuse. $300.00 repair done by myself since the car is not in warranty.
1999 Chrysler 300m - have had the car since 2002. About a year ago we noticed it would stall during operation then immediately restart. Now it has gotten worse. It just stops while at highway speeds, during city driving or even at a light. Usually re-starts right away but lately it takes about 10 minutes before re-start is possible. Took to Dodge dealer and they cannot find the problem. I won't allow my wife to drive the car as it is too dangerous. Any feedback on what the problem is would be greatly appreciated.
