There are 3 owner-reported fuel system complaints for the 2017 Chrysler 300in NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
Filling up the gas results in a strong odor of gas in the cabin and gas leaking out of the right rear wheel well. Also caused the engine to sputter and turn off. Found content in the https://www.300cforums.com/ forum that speaks of the issue.
AFTER I FEEL THE VEHICLE UP WITHOUT TOPPING OFF THE VEHICLE STARTS RUNNING ROUGH AFTER ABOUT 10-15 MINUTES. THE CAR SHUTS OFF AND ERROR MESSAGE COMES UP TO PUT THE CAR IN PARK AND THEN SELECT DESIRED GEAR. THE ENTIRE TIME YOU CAN SMELL GAS BECAUSE THE CAR IS LEAKING FUEL FROM THE RIGHT REAR WHEELHOUSE AREA. THIS IS VERY UNSAFE. I WAS JUST DRIVING ON I95 AND THIS HAPPENED TO ME. THIS VEHICLE COULD HAVE CAUSED A PILE UP ON THE HIGHWAY. PEOPLE COULD HAVE DIED. RECALL
WHEN AC IS ON THERE IS A STRONG ODOR OF GASOLINE EVERY TIME WE TURN AC ON OR IF THE CAR IS IN USE FOR A LONG TIME THE ODOR IS VERY STRONG IN THE CAR, SINCE THIS ISSUE STARTED THE CAR HAS BEEN USING MORE GASOLINE AND I HAVE TO FILL UP THE TANK MORE TIMES THAN USUAL. MY CAR IS STILL UNDER MANUFACTURES WARRANTY AND I SCHEDULED A SERVICE WITH CHRYSLER TO HAVE IT CHECKED OUT BUT THEY DID NOT WANT TO TAKE THE VEHICLE IN TO A SERVICE TECH BECAUSE NO ENGINE LIGHT OR NO CODE WAS PRESENT\. I HAVE TRIED TO GET THEM TO INSPECT THE FUEL LINES TO CHECK IF THERE IS A LEAK OR HAVE THEM CHECK THE AC TO SEE IF THEY CAN FIND THE CAUSE OF THE STRONG ODOR THAT WE GET WITH THE AC ON BUT HAVE HAD NO LUCK. I AM TO THE POINT THAT I AM WORRIED FOR MY HEALTH AND MY CHILDREN'S HEALTH DUE TO THE STRONG GASOLINE ODOR.
