What owners say
Fuel sending unit cracks which lets raw fuel pool directly under backseat.
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.
After refueling, car stalls. This happens after driving approximately 2 to 3 minutes after leaving gas station. The stall has taken place at intersections, while at a complete stop and while driving no more than 5 -10mph after leaving the gas station.. Car restarts after several attempts in neutral. When each incident occurs, the oil icon comes on, however the oil level is not low. On one occasion after having backed into a parking space with the car gear shift still in reverse and my foot on the brake, the car lurched. The tires could be heard spinning. That was very scary because my car could have rolled into a busy highway. Once the fuel level indicates approximately a half a tank, no stalling incidents take place. Car was taken to the dealership with this concerned. Service advisor was aware of chyrsler 300c stalls after refueling. Fuel injection system was serviced/cleaned. This has not resolved the problem. Car still stalling. Really afraid to drive the car, however I am taking it back to the dealership to let them know of the still ongoing problem.
The vehicle will stall out several times after filling the tank with gas and it only stalls out after filling the tank. Vehicle will stall when stopped or when the RPM is low. The problem is the vapor/liquid separator valve located at the top of the fuel tank. The valve is designed to prevent liquid fuel from entering the charcoal canister/emissions system. When the valve fails, liquid gas can enter the line and fill the charcoal canister. After refueling the PCM on the vehicle detects a change in fuel level. Then, when the engine meets certain temperature and driving criteria, the PCM issues a purge command to the charcoal canister to remove the stored gas vapors. It's at that point that all the liquid gas in the line gets sucked into the charcoal canister. The PCM expects to see gas vapors entering the intake manifold and it is prepared to adjust air/fuel mixtures to compensate. However, it is not prepared to see liquid gas coming into the intake. That's what causes the engine to stall. This can be a very dangerous situation with the vehicle on the road in traffic. I've read in multiple online forums this same situation is happening to many on the chrysler 300c early year models. Hopefully a recall will be created to resolve this situation.
After fill up at gas station ( not topping off), when leaving and coming to a stop at an intersection, car will shut off and have to crank two or three times to start again. It will do this several more times after coming to a stop, once on the road or freeway it will run like nothing is wrong. Once fuel level drops enough it will no longer stall when coming to a stop. Have read in forums that the problem is more than likely a valve that is built in into the tank, making this an expensive fix.
This has happen at every fill-up. I've own my chrysler 300c since may 2004 (one of the first to purchase) and this problem has been present since 2008. I have to estimate the amount of fuel to put in the tank at every fill-up. If not, the car will stalled until the excess fuel is burn off or you have to drive on road without lights until the fuel gauge goes a little below the full marker. This problem should be fixed before someone gets killed.
The problem started about 12 months ago. When ever I re-fuel my car it will shut off several times. It seems to happen more frequently if I let the fuel level get to or below 1/4 tank before re-fueling. The problem will continue at least 10-15 minutes after re-fueling. When the problem first started the car would only shut off at idling or at very slow speed. Now the problem will continue to happen even while at street or highway speed. It appears that the fuel flow is interrupted then begins to flow again. This will repeat several times. This only happens after re-fueling. I have not attempted to get it repaired due to no longer having a warranty. My car now has approximately 62000 miles on it.
After filling the fuel tank the engine will stall when stopping for a light or when first leaving the light. It will also jerk while driving.this happens until the fuel level goes down. It did not do this when first purchased. Now it happens every time the tank is filled. If the car stalls while driving the steering and brakes become difficult to use. There are many reports online about this same problem. Chrysler does not claim to know anything about this at the dealer. Someone will get hurt or worse if this problem is not addressed. Thank you
