Vehicle stalls when idling or coming to a stop, mainly at low RPM. No codes are thrown. Gas tank has been replaced and fuel pump is new, still stalls. There are many reports on the Chrysler 300 Forum regarding the same situation. Many people have thrown good money after bad towards parts and still there's issues. I have my car at the Moss Bros Dealership in Riverside Ca. now for 5 days to try and repair this Safety Issue! 3/28/23. Car has stalled approximately 20 times, 4 times which were on the freeway. The car will start up and run fine for several days and then it acts up. Could be a number of things, but with no codes, pretty hard to diagnose the stalling issue.

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.

Fuel vapor was leaking into our car through air vents and from fuel pump itself. It caused the car to fail and not start. Had to replace fuel pump, yet same thing keeps happening. Now gasoline leaks from the outside underneath the car (when driving, or parked but with car turned over) where the fuel pump is non stop.

7/11-5/12, I took my 2006 300c hemi into my dealership for my car stalling after I have driven it past 1/4 tank then fill it up. I was told different repairs was causing the issue. On 5/4/12 I got an answer it was my fuel tank. My warranty ran out 12/10 the dealer wanted $1500 to replace the tank. I contacted chry corp explained what I had been dealing for the last 10 mos. I didn't have money to repair. Chry offered to help had me pay a deductible of $245. My mileage was about 57,000. I was thankful for chrysler helping me out. In 2013 there was a recall on the fuel tank. I called chry corp again and they said yes it is a recall & offered to refund me back for the deductible I paid. Now in 2020 my car is doing the exact thing, (125k mi) wanting to stall/does stall after I ran past 1/4 tank, then fill it up. I took my car to my private mechanic, he told me this is a recall take it to the dealership. I called the dealership, they said my VIN # was not on the list. I called chry corp explained what I was experiencing. They told me they do not take 3rd party diagnosis, I needed to take it to a certified chry dealer. I did and they confirmed it was my fuel tank! Chrysler corp said there's nothing they could do for me my VIN# does not qualify, besides the warranty expired! On the forums I read said this recall is a lifetime recall. I sent my work orders to both dealer & corporate and the dealership said my fuel tank was never replaced just fuel pump. All these years I never let gas tank get lower than 3/4 tank, it was a habit from my prior problems. Until 9/14/20 I ran my gas past 1/4 tank and filled up. As soon as I was driving on side streets when I would come to a stop at a signal and start to go. My car would do the exact same thing as 2011-2012! Sending all my info I was still denied by chrysler to fix fuel tank recall!! Please help, to repair now it's $2500!!!

A lot of others on 300 forums have had the same issue !! So many 6.1 and higher that need that fuel pump but chrysler seems to keep sending me parts and taking my money! Please help
