2015 Chrysler 300: check engine light

Filed Oct 7, 2026 · TX

Finnegan completed manufacturer emissions recall UB4 (evaporative canister) on my 2015 Chrysler 300S, VIN [XXX], on [XXX]. After that repair the check engine light returned. Independent scan showed code P0456 on the same EVAP system. I asked Finnegan to inspect their completed campaign work at no charge. They required a paid diagnostic. Chrysler cases [XXX] and [XXX] were opened and closed; Chrysler said they cannot override the dealer fee. I did not refuse a repair. I refused a paid diagnostic on work already performed under a manufacturer campaign. I want Finnegan to inspect the UB4 work at no charge or explain in writing why a paid diagnosis is required.

2015 Chrysler 300S VIN: [XXX] Mileage: 198,677 Finnegan Chrysler Jeep Dodge Ram, [XXX], completed manufacturer emissions recall UB4 (evaporative emissions canister replacement) on this vehicle. After that repair the check engine light returned. On XXX, AutoZone scanned the vehicle. The only code stored was P0456, EVAP System Leak Detected (very small leak). The scan identified the Emission System Integrity Monitor (ESIM), which mounts on the canister, replaced under UB4. The dealer service advisor, [XXX], said the vehicle would have to be diagnosed again and that I would have to pay for the diagnosis if they found something other than the original recall item. She said a manager would call back. I did not receive a call back. I opened Chrysler Customer Care case XXX. I have not authorized a paid diagnostic or signed a paid repair order. I am requesting that the completed UB4 repair area and related EVAP/ESIM components be inspected at no charge. I am filing this report because the same evaporative emissions system set a leak code after a completed manufacturer campaign, and the servicing dealer required a paid diagnosis before inspecting that work.

I was driving on the highway with cruise and my car started to go limp, then started to accelerate without my foot on the gas. Then my check engine light came on and I pulled off and turned the car off and back on. It drove fine but when I went to have it checked they said it threw a code for my TCM. My coworker also drives a Chrysler 300 and had the same issue in the same week! He never got his checked out but his car stopped accelerating and then started again while on cruise. This is happening to a lot of Chryslers so I looked up recalls and it looks like the TCM was recalled in the 2016 300’s but my 2015 and his 2015 is having the same issues

Car keeps saying service fuel sensor. I bought the car from enterprise rental car in march 2015 and in june 2015 the check engine light came on and the gas tank picture kelp blinking. I took it to chrysler dodge jeep in duncanville ,tx and they supposedly fixed the problem. Well my car have been to the shop 5 times with the same problem over the past 3 yrs. It is currently doing the same thing at this time so this will make the 6th time it has to go to the shop for this issue. My warranty is out and I don't feel I should have to pay for this problem. I can't even get my car to pass inspection until this problem is fixed I don't know if the dealership reported the problem but I reported it to chrysler corporation last year. .
