2016 Ford Mustang Fuel System Problems

On 12/06/2025 I filled the vehicle with gasoline. As I was driving home I noticd a strong odor of gasoline. When I arrived home I parked the car in my carport. A short time later I went outside and noticed that I could still smell gasoline and I looked under the car, which was approximately 3 feet from my house and saw a puddle under it. This could have caused a fire, so I immediately took the car to a repair shop. Approximately one hour later I received a call from the shop informing me that the tank was broken at the top and it would cost approximately $2,600 to replace the tank. The problem was confirmed by Gemba Automotive, Surprise, AZ. I am unaware of whether they have the part available for inspection. There were no warning messages or lights displayed on the driver information system.

The vehicle is leaking fuel profusely right next to the passenger side exhaust pipe. The fuel is coming out of the fuel tank where the plastic is crimped go the fuel vent valve.

Vehicle is 2016 garage kept, just under 18,000 miles. Check engine light is on. Code scanner indicates EGR leak. EGR valve replaced, check engine light reset. No code for about 3 weeks. Started getting gas filler warnings and check engine light back on again EGR issue. Getting ready for a road trip took vehicle to Ford to troubleshoot check engine light. Identified problem as a cracked fuel tank near where the filler connects. I researched what I can on-line and others have this same issue. Wondering if this is a defect?

I am looking for support concerning a possible defect with our 2016 Mustang V6. It appears to be a fuel tank defect. Causing our garage to completely smell like gas when the car is full of fuel. Similar to recall# 15v339-7601. Our car has a hairline fracture (according to our dealership service department). They attempted to repair the issue by replacing the EVAP line, instead found a crack in the EVAP nipple. According to our dealership the emissions warranty expired the week before we reported the issue in 2023. This is upsetting as I feel this is not a maintenance issue and more of a design flaw as Ford changed the design of the fuel tank after 2017. The dealership wants us to pay for this service but this is not our fault they fixed it incorrectly. I feel like this should be a recall or some sort of extended warranty from Ford for a design flaw.

Noticed a fuel vapor odor for a couple of weeks. After filling the fuel tank the odor intensified. Drove the vehicle about 20 miles to my house. I could smell fuel when I exited the vehicle and noticed fuel leaking from the fuel tank. Took vehicle to the dealership, and when the tank was removed found the fitting for the evaporative system connection cracked. (See photos) There is no apparent impact that would have caused the crack.

The contact owns a 2016 Ford Mustang. The contact stated that after refueling the vehicle, there was an abnormally strong gasoline odor inside the vehicle. The vehicle was taken to an independent mechanic and the contact was informed that the fuel tank needed to be replaced because the cap on the fuel tank was fractured. The vehicle was repaired. The manufacturer was contacted and stated there was no recall for that failure. The contact was referred to the NHTSA Hotline to file a complaint. The failure mileage was 31,115. The consumer stated the vent nipple on the top of the gas tank failed.

I have had my 2016 mustang for 5 years already with 29k miles , my warrantee has expired. I recently notice I had check engine light for P0456 Evaporative Emission Leak. I took the car to get smoke test by my local shop mechanic and it came that there fuel vapor coming out of capless filler neck,since every ford model after 2013 don't have gas cap nomore I would have to replace the whole gas filler pipe which is around $500 for part and labor. In other cars you can just change gas cap for 20$ buh since in my case my car doesn't have gas cap i would have to replace the whole gas pipe filler and ford doesnt offer any gas cap for my car. I feel like if i do change my gas filler pipe , mabey couple years from now it's gona start giving same check engine problem. I also feel safety concern i do live in Arizona where gets really hot and with fuel vapor coming out capless filler it might cost a fire. I have 3year daughter that likes to ride in my mustang but i don't let her intill this gets fix i don't want her smelling gas . Im hoping with this recall ford can fix the issue and work on better design and or make a gas cap to fix evap leak without having to spend hundreds of dollards.thank you

DRIVING (IN MOTION)AT A HIGH OR LOW SPEED THE CHECK ENGINE LIGHT CAME ON IMMEDIATELY CHANGE THE SPEED OF THE VEHICLE STALLING WHICH COULD'VE CAUSE ME MY LIFE AND INNOCENT OTHER DRIVER THEIR LIFE WITH THE VEHICLE STALLING AS SOON AS THE CHECK ENGINE LIGHT CAME ON 270 HIGHWAY IN MARYLAND. I TRIED TO DRIVE ON THE STREET TO PARK MY VEHICLE DURING A SLOWING SPEED THIS PROBLEM HAPPENED AGAIN THAT A VEHICLE ALMOSTED REAR END MY VEHICLE DUE TO THE SUDDEN STOP AND STALLING .I PURCHASED THIS VEHICLE BRAND NEW LESS THAN 25000 MILES . I WAS RESEARCHING MANY FORD OWNERS HAD THIS SAME ISSUE WITH LESS OR HIGH MILES . WHY HAVEN'T FORD MAKE A RECALL FOR EVERYONE SAFETY. CODE P144C IS A COMMON PROBLEM REPORTED BY CONSUMERS

FUEL EVAPORATOR VALVE FAULTY. VALVE WOULD STICK OPEN, CAUSING VEHICLE TO STALL DIRECTLY AFTER FUELING. I ORDERED THE PART THROUGH A FORD DEALERSHIP. REPLACEMENT OF FUEL EVAPORATOR VALVE ELIMINATED THE ISSUE. PART COST $45

CAR STALLED RANDOMLY WHILE DRIVING DOWN THE HIGHWAY. PRESSED THE GAS AND WOULD NOT DO ANYTHING. WAS ABLE TO PULL IN A LOT TO GET OUT OF TRAFFIC. CAR WOULD NOT START AGAIN. FULL ACCESSORY POWER WAS ACTIVE. MECHANIC SAID FUEL PUMP AND MODULE. CAR HAS 46000 MILES. FUEL PUMP SHOULD NOT FAIL IN A 3 YEAR OLD CAR.
