"check engine light" came on regularly, prompting visits to the dealer. Was told I wasn't "clicking" the gas cap enough times upon closing it. Number of times to be clicked started out at 3 and eventually moved up to 7, increasing with each return visit until I screamed in the middle of the service area and they actually fixed the problem by replacing the leak detection pump and the natural vacuum detector. Sunroof motor wouldn't run continuously, the switch would have to be pushed repeatedly to get the roof to close, moving a fraction of an inch at a time. This happened on three separate occasions. Parts replaced included the switch, the motor, and eventually the entire sunroof motor assembly. The big problem: car wouldn't start, even after being jumped. This happened on five separate occasions during the first 16 months I owned the car. Parts replaced include the battery (replaced twice) the starter, the starter relay, and finally the powertrain control module. The car was deemed a lemon under the florida lemon law and I was refunded my money from Chrysler under a "byback" program not arbitrated by the state. *k.
