Vehicle had a strong smell of fuel. there are many complaints regarding this same issue on the internet. the offending part was auxiliary fuel pump had to be replaced that is mounted on the top of the gas tank underneath the back passenger seat.
After filling up my gas tank, i noticed the engine light was on and an odor of gas was present in and outside the car. took the car for service. they checked for a gas leak and found it under the rear seat. i will quote the invoice (165567) dayton andrews inc.. "found gas dripping of side for gas tank coming from the top. removed back seat to find connector was not fully installed. they installed connector and clear codes. vehicle checks ok at this time". the service mgr. said "we cleaned up the gas as best we could, and that the odor should dissipate in a few days". it's been a week and i'm afraid to drive the car. when i do, i need to have all the windows down. this i feel is very dangerous. i've never had any kind of major accident and it seems to me that this connection that was not installed properly was done or not done at the factory. updated 10/01/15*lj updated 11/02/2017*cn
Tl* the contact owns a 2011 chrysler 300. the contact stated when adding gasoline to the fuel tank it would spill out. the fuel filler neck caused the fuel tank to malfunction. the fuel fumes would also linger in the interior of the vehicle which made her sick on the stomach. the vehicle was taken to the dealer on four occasions where they replaced the filler cap but the fuel continued to spill back out after refueling. the engine light also continued to illuminate and would not shut off. each time the failure occurred the dealer would repair it under warranty. the manufacturer was not notified of the failure. the vin was unknown. the failure mileage was 2,506.
At less that six-hundred miles on new vehicle had a failure of the electrical/electronic systems controlling fuel to engine. engine management computer (ecu) faulty, causing excessive amounts of fuel to be dumped into engine cylinders.
