Chrysler 300 misfire problems

Filed Jun 24, 2025 · Fuel system · CA

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.

My car has been at the first dealership (Brewbaker Dodge, Montgomery, Ala.) on November 11, 2020. I got the car back March of 2021. The problem of misfires on cylinder 1 side, hesitation when proceeding from a red light, and stalling out. The problem continued so; I took it to another dealership (Stiver Dodge, Prattville, Ala.) in August 2021. I was given the car back in February 2022 stating to me that the problem may correct itself after being driven until after my birthday (March 2022). So, to this date my car is still at the Dealership and Chrysler Star Team has no clue what is wrong with this car. I'm still paying a car note, insurance, and renewing the license plate for this car every year and moth. Chrysler knows that there is an issue with the 3.6L Pentastar engine. No one wants to help me in this situation, but all parties involved wants my money but no real solution(s). I need someone that's going to advocate for me on my behalf. I just want Chrysler at this point to just put a new engine in the dang car and cover the charges at their expense for their defective engine. Chrysler seriously knows what's going. As long as my car has been at this Dealership For over a year, how could the engineers who designed this engine not know what's wrong with? This car has very low miles to be 8yrs old with major issue. And FCA doesn't want to admit to this engine (3.6L Pentastar) being a defective engine. Look at the class action lawsuits pertaining to this. Please Sir / Ma'am help me make sense of this. Thank you.

Misfiring after spark plugs have been changed. Coil was checked as well as injector pulse, which were fine. Engine lights stays on and misfiring happens when car is idle.
