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.

2006 Chrysler 300 Touring 3.5L V6 engine. Car has intermittent stall at slow speeds or at complete stop. Sometimes feels like it stumbles, other times it dies suddenly and unable to tell the engine shut down. I have to put car in park and completely switch the ignition fully off and turn back on to start position. When it stalls while rolling, I have to brake and bring car to full stop, with no power steering, and go through the same start procedure. No trouble codes are generated, and no check engine light indicator illuminated. Car usually starts right up, but sometimes I have to keep cranking starter, stumbles to catch as if starving for fuel. A/C was on first two times but also happens with A/C off. Research online reveals an open recall for the fuel tank on the 300C model with a 5.7L or 6.4L engine. Problems described on the 300C model are nearly identical to what my 300 Touring is experiencing. PCM replacement does not correct problem. Some noticed it happening only with a full tank. Stopgap measure is to only fill no more than 3/4 tank. I am currently testing this idea. The safety issue is significant and twofold; three times I have had one other adult and two children in the car. While stalled at a major intersection traffic signal trying to restart the engine, other vehicles approached from the rear at 50-55 MPH. A rear end collision with children in the back seat would likely be fatal. Secondly, during a stall event while the car is moving, it is extremely difficult to steer the vehicle to a safe place, and braking takes significant pedal pressure once power assist bleeds off. This is a serious concern and obvious collision hazard, as I may not be able to stop or steer to a safe location or avoid a hazard. I had the car at the dealer for over three weeks in July 2024 and they were unable to duplicate the issue. Their answer was to drive car until it happens more frequently. This is unacceptable. No other solution or repair was provided.
