2012 Jeep Wrangler Fuel System Problems

Having a hard time putting gas, I have to do it slowly so it can go in, the worst is when I put fuel a bit more fast it will throw gas out even if it ain't even close to half the tank.

When the fuel vents on the top of the fuel cell get old, they are extremally brittle. Washboard roads or a pot hole can jar the fuel tank breaking the connectors that go to the emissions system and the rollover valve. If any of these plastic pieces break, there is a chance for fueling problems and effects the drivability of the vehicle. The 3 connector vent is a non-serviceable part, requiring the gas tank to be replaced. The replacement has the same plastic connectors, leaving the possibility for breakage. These connectors breaking can lead to a multitude of issues, including but not limited to fuel spills while filling, leaking fuel from hoses. I have had 2 tanks in my 2012 jku have this issue and a quick search on jeep forums will show that this is not an isolated problem.

The skid plate assembly that retains the fuel tank is very corroded, corroded to the point of the fuel tank dropping out of the vehicle if not repaired as soon as possible. The other part of this issue is when trying to get this part, there is a backorder of approximately 50 of the skid plate assemblys! This information was provided to me by the Chrysler/ Dodge/ Ram /Jeep Dealership from where we purchased the vehicle new, and that has done all of the repair work on this vehicle since we bought it. The 2 things I find to be very concerning with this issue are the potential fire hazard if, and when a fuel tank were to fall out of the vehicle and the issue of a parts back order appears to show there is an ongoing issue with this very serious situation . Also this vehicle has never been used off-road or for any extreme off-road activities, solely on road use. I did contact Chrysler in regards to my concerns, but other than attempting to get the part shipped sooner, I was told the vehicle is out of warranty and there is no recall on it so there is nothing they can do.

Occasionally we would smell gasoline fumes. The occurrence became more frequent to the point we had a mechanic check it out. The mechanic dropped the gas tank and found that there is a steel ring between the tank and the fuel pump flange. This flange had rusted and expanded to the point of cracking the fuel pump flange. Mechanic replaced the flange, seal and fuel pump. I have retained the cracked fuel pump.

The contact owns a 2012 Jeep Wrangler. The contact stated that while refueling, fuel spilled out when the automatic shut off activated on the fuel pump. The contact stated that the failure recurred. No warning light was illuminated. The vehicle was not diagnosed or repaired. The dealer was not notified of the failure. The manufacturer was notified of the failure however, no assistance was provided. The failure mileage was approximately 75,000.

SUDDEN ACCELERATION WITH BRAKES NOT RESPONDING .THIS HAS HAPPENED 4 TIMES AND ONLY WAY WAS TO PULL OUT OF ROAD AND JAM BRAKES AND DISENGAGE FROM DRIVE TO PARK IN A MOMENT TO AVOID ACCIDENTS OR ME DRIVING OF THE SIDE ROAD . THIS WAS REPORTED TO DEALERSHIP AND NOTHING CAME BACK WITH NO CHECK ENGINE LIGHT ON. I ALWAYS DONE MY SERVICE AT DEALERSHIP AND APPARENTLY SUPPOSEDLY NOTHING HAS BEEN REPORTED OF THIS NATURE.IT FEELS LIKE IT'S ON CRUISE CONTROL WITH HAVING A SPEED OF IT'S OWN BUT BRAKES ARE NOT RESPONDING NORMALLY. HOPEFULLY CAN ADDRESS ASAP LUCKY I'VE BEEN WORKING FROM HOME BUT I SHOULDN'T BE AFRAID TO DRIVE MY OWN CAR. THIS IS A VERY SERIOUS SAFETY ISSUE AND NEEDS ATTENTION ASAP.THANKS MB

WE USE THIS JEEP ONLY FOR HIGHWAY TRAVEL. IT HAS 48,000 MILES. ON OUR WAY TO CHURCH, YES UNBELIEVABLY WE HAD A STRONG SMELL OF 'GASOLINE' ONCE WE ARRIVED BACK HOME THERE WAS A STEADY STREAM OF GASOLINE RUNNING DOWN THE BELL HOUSING OF THE TRANSMISSION TO THE GROUND, THIS WAS IN AN AREA ABOUT UNDERNEATH THE FRONT SEATS OR NEAR THE REAR OF THE ENGINE. THIS LEAK OCCURRED ONLY WHILE THE JEEP WAS IDLING. ONCE WE TURNED THE ENGINE OFF, THE GASOLINE STOPPED LEAKING OR RUNNING DOWN THE BELL HOUSING. THE GREATLY ALARMED US DUE TO THE POTENTIAL IT COULD EASILY HAVE IGNITED TO FLAMES SINCE THIS WAS VERY FLAMMABLE GASOLINE LEAKING WAS SO CLOSE TO SO MANY OTHER HOT EXHAUST PARTS. WE HAD TO TOW THE JEEP (OBVIOUSLY NOT DRIVING IT LEAKING SO MUCH GAS ANY LONGER) TO OUR JEEP DEALER SERVICE CENTER FOR FURTHER INSPECTION AND REPAIR. THEY DISCOVERED A SMALL LENGTHWISE SPLIT IN THE FORWARD HARD PLASTIC FUEL LINE SEVERAL INCHES FROM WHERE IT ATTACHES TO THE FUEL RAIL. THIS IS THE FUEL LINE TUBE THAT GOES TO THE END OF THE ENGINE. I HAD SEVERAL TIMES REQUESTED THE JEEP DEALER TO SAVE THE OLD DEFECTIVE PARTS BUT THEY THREW THEM AWAY. I HONESTLY DONT KNOW IF THAT WAS BY DESIGN TO AVOID A RECALL OR NOT, I CERTAINLY WOULD HAVE PHOTOGRAPHED THE SPLIT WOULD I HAVE HAD THE PART.

JEEP WAS GETTING OVER 20MPG THEN SUDDENLY STARTED DROPPING AT A RAPID RATE NOW 1YR AFTER PURCHASE IS GETTING AVERAGE 12.9MTG. DOWN TO 9MTG. HIGHWAY OR TORREVIEJA DOESN'T APPEAR TO EFFECT THESE NUMBERS, NOT IN WRONG GEARS, OIL CHANGES CURRENT, TIRES BALANCED AND AIR CORRECT.

ENGINE LIGHT CONTINUES TO COME ON AFTER SEVERAL REPAIRS A SENSOR WAS REPLACED. THE ENGINE LIGHT IS ON AGAIN I HAVE READ SEVERAL REVIEWS AS TO CYCLINDERS ARE MISFIRING THIS IS A MANUFACTURING PROBLEMS THAT NEEDS ADDRESSED BY THE MANUFACTURER

FUEL IS OVER FLOWING FROM FILLER TUBE WHEN AT THE GAS STATION. FUEL RUNS DOWN THE SIDE OF VEHICLE AND ON TO THE GROUND. THIS HAPPENS ALMOST EVERY TIME I FILL UP.

WHEN I FILL-UP MY GAS TANK, THE PUMP DOES NOT SHUT OFF PROPERLY AND GAS OVERFLOWS TANK, SPILLING ONTO REAR QUARTER PANEL, BUMPER, AND GROUND SURFACE. AT TIME OF FILL-UP, VEHICLE IS STATIONARY, PARKING BREAK ON, AND ENGINE OFF. THIS OCCURS PRACTICALLY EVERY TIME I FILL UP GAS TANK, AND OCCURS AT DIFFERENT GAS STATIONS. HENCE, THIS PROBLEM IS NOT CAUSED BY THE GAS STATION PUMPS, AND APPEARS TO BE CAUSED BY MY VEHICLE NOT SHUTTING OFF PUMP BEFORE GAS OVERFLOWS TANK. I RESEARCHED THIS ONLINE, AND IT APPEARS THIS PROBLEM IS COMMON TO JEEP WRANGLER OWNERS, AND JEEP IS AWARE OF THE PROBLEM, BUT HAS NOT DONE ANYTHING TO FIX PROBLEM. OVERALL, THE OVERFLOWING OF GAS FROM TANK UPON EACH FILL-UP PRESENTS A SIGNIFICANT RISK TO VEHICLE OWNERS AND GAS STATION ATTENDANTS (NOTE: I LIVE IN NJ, AND STATE LAW REQUIRED GAS STATION ATTENDANTS, I.E., NOT VEHICLE OWNERS, TO PUMP ALL GAS INTO VEHICLES). I BELIEVE JEEP SHOULD DO SOMETHING TO CORRECT THIS PROBLEM, AND UNDERSTAND THAT THEY INITIATED A VOLUNTARY RECALL FOR 2007 TO 2009 JEEP WRANGLERS, BUT NOT LATER MODELS.

WHEN I FILL UP AT THE GAS STATION, AND THE FUEL PUMP CLICKS OFF, FUEL SPILLS OUT EVERYWHERE. EVERY SINGLE TIME.

BAD FUEL PUMP

WHEN FILLING THE GAS TANK, ONCE IT REACHES THE FULL POINT, IT FAILS TO TRIGGER THE FUEL PUMP TO STOP IN TIME AND FUEL SPILLS ALL OVER THE SIDE OF THE REAR FENDER. IT DOES THIS EVERY SINGLE TIME I FILL UP.

JEEP WAS STALLING. HEAD WAS REPLACED UNDER WARRANTY. ONE MONTH LATER JEEP STILL RANDOMLY STALLS AT IDLE / STOP LIGHTS. NOW IT IS STARTING TO CUT OUT AT ROAD SPEEDS.

I BOUGHT THIS WRANGLER ON 5-30-2015. THE FIRST TIME I TOOK IT TO FILL UP THE GAS TANK, I WAS EXPOSED TO THE FACT THAT THE TANK DOES NOT SHUT OFF AND OVERFLOWS ALL OVER THE JEEP (AND ME). THIS HAS HAPPENED EVERYTIME WE GO TO FILL UP, TO WHERE WE HAVE TO WATCH THE FUEL LEVEL ON THE INSTRUMENT PANEL TO MAKE SURE IT DOES NOT GET ALL THE WAY TO FULL. THIS INDEED HAPPENED AGAIN JUST A WEEK AGO SUNDAY WHEN WE WENT TO FILL UP AND I WAS SPEAKING WITH A GENTLEMEN WHO HAD JUST BOUGHT HIS JEEP AND I WAS TALKING TO HIM ABOUT HIS AND IF HE HAS HAD ISSUE WITH HIS GAS TANK OVERFLOWING. AS I WAS TALKING TO HIM YEP, YOU GUESSED IT, IT OVERFLOWED. NOW, I READ TODAY THAT CHRYSLER HAS SAID THAT IT HAS TO DO WITH THE TYPE OF FUEL YOU PUT INTO THE TANK?? REALLY??? SO I HAVE PUT IN ANYWHERE FROM 85, 87, 90, AND HIGHER GRADE FUELS, AND IT STILL HAPPENS? NEXT ARE THEY GOING TO SAY IT IS THE GAS STATION COMPANY I GO TO? THE WAY I PUT THE NOZZLE INTO THE TANK? (DOES THIS SOUNDS SARCASTIC WHEN YOU READ IT? GOOD) I FIND THAT COMMENT FROM CHRYSLER ABSOLUTELY DEMEANING AND IDIOTIC!!! IT HAS BEEN A KNOWN ISSUE ON SEVERAL PREVIOUS MODELS OF JEEPS, BUT FOR SOME REASON THEY ARE GOING TO IGNORE THIS ONE? WHAT WILL IT TAKE CHRYSLER? WILL IT TAKE A CLASS ACTION LAWSUIT TO GET YOUR COMPANY TO FIX THE PROBLEM? I NOW JUST READ A REPLY THAT SOMEONE HAD CONTACTED A LAW FIRM IN REGARDS TO A CLASS ACTION SUIT AND THAT IT HAD BEEN TRANSFERRED TO BANKRUPTCY COURT IN NEW YORK WHERE IT WAS STILL ALIVE AND THAT THE COURT HAD GRANTED CHRYSLER'S MOTION TO DISMISS STATING THEY ARE BARRED BY THE SALE ORDER BETWEEN BANKRUPT CHRYSLER AND THE NEW CHRYSLER. WOW!!! GREAT BUSINESS MODEL. LETS FILE BK. (ONE OF THE QUESTIONS ASKED AT THE BOTTOM OF THIS COMPLAINT FORM IS WHEN DID THIS HAPPEN? EVERY TIME I FILL UP SINCE 5-30-2015!!!

FUEL SPRAYS OUT OF THE FILLING TUBE WHEN REFUELING TO A FULL TANK.

GAS SPILLS OUT OF THE GAS TANK WHEN FILLING UP. HAPPENS AT DIFFERENT GAS STATIONS, BOTH WITH THE HANDLE CLIPPED IN THE PUMP POSITION AND ALSO WHEN GRIPPED BY HAND THROUGHOUT. VERY DANGEROUS AS IT HAS GOTTEN ON MY HANDS AND CLOTHES AND ALL OVER THE CAR. VERY FLAMMABLE SITUATION. *TR

UPDATE TO COMPLAINT NUMBER 10692609 REGARDING THE CHECK ENGINE LIGHT AND CODES P0441 AND P0445. A NEW MOPAR GAS CAP HAS TAKEN CARE OF THE PROBLEM. TWO AFTER MARKET GAS CAPS, PURCHASED NEW, WERE FAULTY RIGHT OUT OF THE BOX. THE NEW MOPAR GAS CAP HAS CLEARED THE CODES. APPARENTLY NOT ALL GAS CAPS ARE VEHICLE SPECIFIC... *TR

MY CHECK ENGINE LIGHT CAME ON. THE CODES WERE P0441 AND P0445, BOTH HAVING TO DO WITH THE EVAP SYSTEM. *TR
