What owners report
After filling the car with gasoline, I get a strong odor of gasoline in the cabin of the car. After the fuel level gets to about 7/8 full the issue goes away. After further inspection the odor seems to be strongest in the passenger side aft wheel well. Excessive fuel vapors are harmful to people and could cause explosion or fire.
After filling tank with fuel, car smells from fuel. Fuel vapor comes out ac vents, fills cabin. Very bad after sitting parked. Odor fades and stops when fuel level reaches about 7/8 of a tank. Took it to mechanic and mechanic says he found fuel on top of starboard fuel pump. Fuel pump mounting bracket has hairline cracks in it. Needs complete replacement. This same problem and one related to the fuel pump seal are recorded in forums all over the internet. Why is there no recall? This is a very serious problem. Vehicle is currently awaiting repair parts. Apparently Chrysler (not nhtsb?) is aware of the problem as the local dealer ordered 500 replacement units for inventory. Vehicle is in ny and mechanic found 1 (one) available from san diego, california. I would say there is a problem with this part.
There is a fuel smell in the car, for the first 1/4 tank of gas. The smell is really bad in the back seat. After the car is under 1/2 tank the fuel odor begins to subside. Passengers in car begin to have headaches and upset stomachs. After veiwing other chrysler forum's - I believe this to be common with this style of car and an extreme Safety issue
Engine stall immediately following fuel tank fill up. Chrysler refuses x53 lifetime extended warranty. Service bulletin 14-002-14 Applies to 2005-2006. I own 2008. Identical car. Identical problem. Happens every time fuel is filled.
Car dies right after filling the gas tank. This has happened numerous times while driving at a low speed, idling away from the gas pump, or stopped at a stop sign or traffic light. Last time this happened, I was almost hit in the rear at a traffic light when the car stalled. Local Chrysler dealership acknowledged the problem was a faulty part that is molded into the 19 gallon fuel tank but said my car wasn't covered. My mechanic verified that the "rollover" valve in the tank was indeed faulty. Have talked to Chrysler twice about this problem but they have flatly refused any assistance even though they agreed that my car has a 19 gallon tank. I know that Chrysler has already had to replace over 150K of these faulty tanks. Mine is faulty also but they will not do anything. This is a serious and dangerous situation. I have parked the car for now out of concern for safety.
Vehicle dies while driving and wile coming to a stop in town. No check engine light. 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 5 times and wont always re-start. Sometimes it takes 5-10 minutes, and other times it starts right back up. This recent issue happened less than two weeks after having a leak detection pump replaced.
The contact owns a 2006 Chrysler 300C. The contact stated that the fuel tank was previously replaced under an unknown extended warranty coverage; however, after the repair, the vehicle experienced a failure. The contact stated that after refueling the vehicle and driving at slow speeds, the vehicle stalled. The contact stated that the failure recurred several times while driving and coming to a complete stop. The vehicle was towed each time the failure occurred. The contact stated that the vehicle stalled in the middle of the road during the last failure. The contact was able to push the vehicle to the side of the road with assistance. The vehicle was towed to the residence. The vehicle was then towed to the dealer, where it was diagnosed and test-driven, but the cause of the failure could not be determined. The vehicle was not repaired. The failure mileage was approximately 214,624.
My Chrysler 2006 300 C smells of heavy oder of fuel inside occupant seating area. upon investigation, found the fuel pump situated behind driver, under back seat, and the modulator is situated behind passenger seat. both fuel and assembly are exposed to occupants, leaking and accumulating pools of fuel. there is no safety barrier between the fuel and occupants! this is a critical DESIGN FAILURE for occupant safety!!! The modulator is made of plastic and exposed to caustic chemicals (fuel) which causes premature corrosive damage exposing all occupants of vehicle to multiple health risks including DEATH!! This vehicle needs to be recalled!!! and not only fix the issue with leaking fuel, the vehicle needs a fire proof barrier between the fuel system and the occupants.
