please help with 300..

Does it have the 19 gal fuel tank? There is a recall for the fuel tanks on them due to the rollover valve becoming distorted and shutting off the fuel flow. The NTHSB forced Chrysler to do a recall and give an owner independent lifetime warranty on the 19 gal fuel tanks as a result of stalling and non-start issues. I think the 3.5L AWD cars had the 19 gal tanks in 2007. If you have the 19 gal tank, Chrysler will replace it for free under the lifetime warranty.

Hmmmmm, interesting..next problem will be getting in to a dealer.. The mopar dealer around here stays so damn busy they act like they don't even want to talk to you. They stay at least 2 weeks behind.
