I have 130k mileage on my Chrysler 300 2007 model. For about 3months, I've been experiencing fuel leaks from the bottom rear corner of the driver side just directly beneath my fuel tank, which also makes both the exterior and interior of the car smell of gas. I took the car for maintenance and the fuel tank seals were replaced after my fuel pump was changed. There was no visible fuel spill after the rear seats were removed and inspected but there was constant droplets of fuel from beneath the rear left side of the car. I don't know what else to do and what can cause this?.. besides, whenever I put fuel in my tank, I can smell fuel coming from the AC vents. Also, my airbag warning light has been on for a long time on my dashboard. Help!!!
Engine constantly leaking coolant from multiple areas on the engine. Have had to constantly get it repaired at least once a month. Also have had constant cylinder misfires, fuel injector system keeps going bad
My car will outright just stop for no reason. I will sit at a light and the RPM guage will start going out of control and the car will rev on its own. Then I will start driving and ti will be find until I go to press on the brakes. Then the whole car will cut out. I'm able to get it to turn over again after two or three efforts of turning the key and pumping the brake. It has once done it with my daughter in the car, which I am not okay with. Luckily, we were turning into a neighborhood and not onto the highway into high speed traffic. It turned off and on about 7 times down the road before it started running properly again. It seemed to happen every time I would hit the brakes or attempt to turn. The car cut out like it had run out of gas even though there was plenty in the tank. …
Vehicle dies while driving and wile coming to a stop in town. No check engine light. No codes - took it in to the Chrysler dealership and they diagnosed a bad fuel tank. The inlet flapper on the fuel tank is defective allowing fuel to overflow the charcoal canister. This is the same problem as the 2005-2006 models that now come with a lifetime warranty on fuel tanks. I called Chrysler and they are not willing to work with me to replace it or consume some of the costs, and it is a safety issue. It has dies out in the middle of an intersection over 10 times and wont always re-start. Sometimes it takes 5-10 minutes, and other times it starts right back up. I was in the middle of a turn and the car stalled out and I almost hit the vehicle to the right of me. It is very dangerous and needs to be included in the lifetime warranty issued to 2005/2006 models.
At various times since I bought this car new, this vehicle stalled and/or violently shook while at stop light thinking someone must have hit me. When filling up with premium gas, the pump will trip and stop putting gas. I have to hold the pump slightly higher so that it will not trip. I could never use the pump rest for this car so that I don't have to hold the pump the entire time. We even choose gas stations that do not have ethanol mix. On Tuesday, 2/7/17, it shook and stalled at different times during the day while at stop light. On the same day, while in motion and making a curve on a narrow 2-way street, I suddenly could not steer the car. I stopped with my emergency flashers, turned off everything, and had to restart the car. We took it for service for same reasons and the dealer could not find any issues.

A part within the fuel tank needed replacement along with the fuel tank. The vehicle was not repaired. The manufacturer was notified and did not assist. The contact mentioned that the 2005 and 2006 Chrysler 300 had a recall for the same failure. The failure mileage was 63,000. Updated 9/19/18
I purchased a 2007 Chrysler 300 at the end of 2012 with 24K miles on it. Since purchasing it the car has continued to stall - while in motion at speeds of 55 MPH and while under 10 MPH. I have invested a considerable amount of money over a two year period trying to remedy the problem including the replacement of the purge valve in December 2014. The car stalled again today while driving 50 MPH, and was difficult to restart.
Car shut off while driving, there was a strong gasoline odor coming from underneath the vehicle, turned back on after a few minutes,gas cap light came on, went to autozone to run scanner and got code p0440, checked all EVAP components and lines and noticed something loose on top of fuel tank, rollover valve popped off and there was fuel all around it... I'm lucky there were no sparks from anything,had a full tank!
