Chrysler 300 fuel pump problems

Filed Mar 20, 2026 · Fuel system, Seat belts · 257,139 miles · TX

I have a 2010 Chrysler 300 and when I fill my tank up I take the handle out when it clicks I don’t keep filling because I know not to. My car will smell like someone poured gas into my backseat and if I roll the driver side window down for air it seems to get stronger for a little over 3 months now until it gets a quarter in a half below full. Now I don’t fill my car up all the way due to that and no one has figured it out yet. I have replaced lines and caps and now the fuel pump to find out none of it was the problem. I was followed home tonight to be told my car was pouring out gas from under the fuel pump area while I was driving. So I took a video of it pouring out under the driver back seat area and then I pulled off the back seat to find gas all on top of my brand new fuel pump. First I figured maybe the seal wasn’t on right but everything was put on correctly but yet I have no clue why there is gas everywhere especially seeing the pump is in correct. I can’t drive my car nor take my grandson anywhere with my car smelling like gas. Not understanding why my old and new fuel pump is backing up and I wouldn’t run my car on empty nor overfill. I have spent a bit of money into my car replacing things to continue to have the same problem. Major issue scared to ride in my car not knowing if it is going to catch on fire and that is my main transportation. By the way I changed my fuel pump because my car wouldn’t start yesterday and I didn’t hear the fuel pump turning on so tapped it a few times and it clicked on and it was whining so loud I parked it a few blocks away at a family members house scared to be stuck on the side of the road going home yesterday. Seatbelt lock box quit working as well I literally have to push it in 50 times to get it to click very irritating especially if you are in a hurry but that is way minor compared to my gas issue for the last few months Wish I could share video to show gas pouring out can’t see in pictures

I bought my car, Chrysler 300 2021 at the Hemet CA Dealership in 2021. Hemet Chrysler Dodge Jeep Ram. The car presented with several issues including, difficulty starting, engine misfires, stalling, and decreased fuel efficiency. The low fuel warning light on my car's dashboard would not come on when gas was low at all, until it left me stranded in the freeway far away from home and a dealership. I had to take it in to closest car service center to have the fuel pump replaced. These fuel pumps should last for 100,000 miles or more. My car had only 69,101 miles. The gas level on the dashboard was stuck at the level when I added gas the last time, again not indicating that it needed more gas. I do not see any recalls issued on FUEL PUMP for my cars year, make and model. But a lot of people have reported the same issues. Can someone respond to this email? I want Chrysler to understand that this is not acceptable. This issue should be part of a recall.

The computer issue has been on going for a while. The computer screen jumps around on its own changes air and heat settings, radio settings, blanks out on the rear view site while in use. Transmission skips on take off and bumps when changing gears particularly reverse and park...... Recently, last week, the car cut off in the middle of turning into a drive way no warning light or sign of distress. I attempted to start it and it just clicked like it was out of gas but wasnt. The (p) for parking kept blinking because it would not go in park completely so it never started . I had to use the parking brake to prevent it from rolling. I towed it to a auto repair shop and it was determined that there was an electrical fault with the fuel tank. So almost 1,ooo$ later it was replaced and its running however the transmission is not quite right. Im concerned about the fuel pump issue because it was sudden with no type of warning light etc. Theres been no "park outside recall' for this VIN# and I would like to know what I should to do to somewhat ensure my safety . Thank you for your consideration during this difficult time. I hope to hear back with a solution or advice.

Main Fuel Pump and accompanied electrical connect. The fuel pump and electrical wiring harness is available upon request. My safety was at risk due to a faulty electrical connection inside the fuel tank. My vehicle made a loud hmming sound at a stop sign, upon continuing forward the vehicle shut off randomly. Upon inspection, the fuel was not sending to the engine. We bought a new fuel pump and replaced at the side of the road. When inspecting the OEM fuel pump and accompanied electrical connection, we noticed over heated wiring and melts plastic inside the fuel tank on the underside of the fuel pump, as well as burnt connections on the outside of the fuel tank on the tip side of the fuel pump. We have pictures to support. No warning signs, signals, or lights were present at the time of failure. When purchasing new fuel pump, there were no instructions for replacement of electrical connections. The only indication we found as to what was happening was through public forums online, showing the electrical wiring was faulty and needed replacing with the alternative wiring harness due to wiring (hot wire, b+) being located too close to the grounding wiring causing it to burn amd/or arch creating a problem with which could cause fire and explosion. No information was readily available nor have we received any information on potential catastrophic injury or failure.

Strong fuel smell in cabin and outside of car when gas tank is full. Discovered gas in the cabin sitting on top of the fuel tank under the passenger-rear seat. Multiple posts in online forums confirm this is a known issue. Vehicle owner ordered a new o-ring to attempt repair. Area around fuel pump under driver's-rear seat was not affected. No warning lights, notices or performance issues. Only indication is strong gas fumes in car after filling up the gas tank (auto shutoff at pump, not topped off) which persists for several days. Problem seems minimized if gas tank is shorted 2-3 gallons from max capacity on fillup (about 14 gallons when car is close to empty per the gas gauge in dashboard.) Car was not inspected by dealer, insurance agent, police, independent service center, or anyone else other than owner.

Engine stalls after fueling tank. This has been confirmed by an independent service center. Spent months and lots of dollars trying to fix problem. Did research on internet and found chrysler had issued bulletin 14-002-14 showing there a problem with chryser 2005 and 2006 300's stalling. The fuel pump is in the tank and not monitored by engine computer. The fuel pump had gone bad causing the car to stall. Called chrysler and they said that the bulletin did not cover my model. Can not use car now because it is a safety hazard. Need help on this issue.

Took my car to the dealer to have the fuel pump replaced. Car was repaired and picked up only to have it returned for a fuel leak complaint. Dealership said there was no leak nor evidence of a leak, however, the car is leaking fuel. After my experience I searched for any information on this topic and found others that have had a similar issue with the repair/complaint. This has not been resolved after a call to the dealership owner.
