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.
Engine Stalls Randomly while Driving. Will crank over several times and over approx 10-15 min. of cranking(Say every 3-5min) vehicle will and will restart. No check engine lights and no warning. The loss of power can be dangerous since brake and steering assist require engine to be running. Vehicle will be fine for several days local commute and problem will recur without warning, usually on longer commute. Vehicle is unsafe and unpredictable.
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.
While driving making a turn, shifting from 1st to 2nd gear, and vehicle stalls losing all power. The vehicle has been to the deal multiple times and the issue can not be duplicated. The vehicle has been inspected multiple times and there are no known issues. No-fault codes are thrown. I stalled in the middle of a busy intersection, with my children in the car. I had to push the vehicle to safety!
While driving the car stalled. Loss of power steering and braking. I was able to coast to a safe location. I tried to restart, but Crank- No Start.
While crossing an intersection the vehicle stalled for no reason. No Codes were posted. Crank No Start, waited 10 min, and the vehicle started. Drove to the dealer to resolve. Dealer has no known reason for stalling while driving
While driving making a left-hand turn, crossing an intersection the vehicle stalled. Lossing all power, no power stirring or breaks. When trying to re-start vehicle will not re-start.
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
THE VEHICLE IS STALLING WHILE DRIVING OR ACTING AS IF ITS GOING TO CUT OFF WHILE IN MOTION CAUSING A VERY UNCOMFORTABLE JERKING MOTION. IT ALSO POWERS OFF AND WILL NOT MOVE UNTIL 3-5 MINUTES LATER REGARDLESS OF WHAT GEAR IT'S IN. THIS VEHICLE HAS CUT OFF ON ME NUMEROUS TIMES WHILE DRIVING AND HAS EVEN CAUSED ME TO BE STUCK IN THE ROAD BLOCKING TRAFFIC. I'VE CONTACTED THE DEALERSHIP MULTIPLE TIMES OVER THE PAST FEW MONTHS AND I ALSO HAVE DIAGNOSTIC RECEIPTS THAT CLAIM THEY CAN'T FIND ANY ISSUES WITH MY VEHICLE WHEN THEY INSPECT IT. HOWEVER, ABOUT A WEEK AGO I WAS WATCHING CHANNEL 4 NEWS AND THEY REPORTED A RECALL FOR 2011-2013 JEEP GRAND CHEROKEE AND DURANGOS FOR ENGINE STALLING ISSUES RELATED TO THE FUEL PUMP. I ALSO FIND AN ARTICLE ONLINE RELATED TO THIS ISSUE AS WELL (HTTPS://WWW.USNEWS.COM/NEWS/US/ARTICLES/2019-11-21/JEEP-DODGE-SUVS-RECALLED-DUE-TO-RISK-OF-ENGINES-STALLING). I WOULD LIKE FOR THIS ISSUE TO BE INVESTIGATED BECAUSE IT'S A MAJOR SAFETY CONCERN.
UNDER HARD ACCELERATION, LIKE PASSING A CAR ON THE HIGHWAY, THE VEHICLE GOES INTO LIMP MODE WHICH HAS NEARLY CAUSED ME TO WRECK 4 TO 5 TIMES DUE TO BEING UNABLE TO ACCELERATE. ONCE I PULL OF THE ROAD AND RESTART LIMP MODE GOES AWAY BUT THE ENGINE LIGHT STAYS ON. THE DEALERSHIP SAYS THAT THE WIRING HARNESS IS THE ISSUE. THE VEHICLE HAS CODES POPPING UP ABOUT TORQUE MANAGEMENT. I WOULD LIKE FOR THIS TO BE FIXED FREE OF CHARGE DUE TO THE WIRING HARNESSES BEING AN INTEGRAL PART IF THIS VEHICLE.
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
VEHICLE STALLED WHILE IN MOTION ON A HIGHWAY. THIS HAS BEEN A CONSISTENT ISSUE FOR THE LAST SEVERAL YEARS. I BELIEVE IT FIRST OCCURRED IN 2016. THE VEHICLE WILL JUST STALL ON A CITY STREET, IN A RESIDENTIAL AREA, OR EVEN ON THE HIGHWAY. FUEL WAS NOT RELATED AS IT HAS HAPPENED ON A FULL TANK OF GAS OR A QUARTER TANK. IT WAS TAKEN TO THE JEEP DEALERSHIP ON MULTIPLE OCCASIONS (THAT HAS BEEN DOCUMENTED) BECAUSE OF THIS DANGEROUS HAZARD, AND THEY WERE NOT ABLE TO REPLICATE SO IT WAS NEVER FIXED. I EVEN SHOWED THEM VIDEO EVIDENCE 3 TIMES. THE VEHICLE JUST STALLS RANDOMLY WHILE DRIVING (IN THE MIDDLE OF HIGH SPEED TRAFFIC). THE RPM WOULD JUST GO TO ZERO, AND WHEN TRYING TO START THE CAR BACK UP, IT WOULD TRY TO CRANK, BUT WOULD NOT START. THE CAR WOULD HAVE TO BE TURNED OFF FOR 5 MINUTES AND THEN THE CAR WOULD EVENTUALLY START AGAIN. THIS WOULD OCCUR AT LEAST 1/MONTH FOR SEVERAL MONTHS. THE JEEP DEALERSHIP REPLACED FUEL PUMP, AND CHECKED OTHER COMPONENTS AS THE ENGINE LIGHT NEVER TURNED ON, AND THEY COULD NOT FIND THE RESOLUTION TO THIS ISSUE. THIS IS A HIGHLY DANGEROUS PROBLEM AND SEEMS TO BE VERY COMMON AMONG THIS MODEL YEAR JEEP, AND JEEP CONTINUES TO CLAIM NO FAULT. SOMEONE COULD DIE IF THEIR CAR STALLED ON THE HIGHWAY WITH CARS GOING 70+ MPH. AN EXPERIENCED DRIVER MAY BE ABLE TO MANEUVER, BUT CERTAINLY AN INEXPERIENCED DRIVER WOULD NOT. THIS VEHICLE WAS INTENDED TO BE FOR A TEENAGE CHILD, BUT I COULD NOT KNOWINGLY GIVE THIS TO THEM HAVING THIS UNRESOLVED ISSUE. AFTER MUCH RESEARCH, I BELIEVE IT IS A FAULTY OR DEFECTIVE CRANKSHAFT POSITION SENSOR, BUT JEEP REFUSES TO ACKNOWLEDGE THIS AND CONTINUES TO SAY THIS IS NOT THE ISSUE, YET THE CAR HAS CONTINUED TO STALL ON VARIOUS OCCASIONS STILL. THEY SHOULD BE LIABLE FOR ANY SERIOUS INJURY OR DEATH THAT MAY POTENTIALLY OCCUR! I WILL BE TAKING THIS VEHICLE TO BE REPAIRED ELSEWHERE AFTER MY OWN RESEARCH AND TROUBLESHOOTING.
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.
PERSONAL MECHANIC HAS NOTICED OIL FILTER HOUSING IS LEAKING AND HAS A HIGH CHANCE TO BE FIRE HAZARD WITHOUT WARNING.
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.
GAS TANK CRACK LEAKS FUMES, ALSO THE TRANSMISSION POPS OUT WHILE DRIVING AND DEALERSHIP WOULD NOT FIX UNDER WARRANTY BECAUSE THEY SAID IT DIDN'T HAPPEN WHEN REPAIRMAN TEST DROVE IT. NOW ITS COMPLETELY BLOWN OUT DOES NOT WORK HAS 36,700. MILES ON IT 700 MILES PAST WARRANTY AND ONE YEAR PASS WARRANTY. THESE ARE TWO DEFECTIVE PARTS AND EITHER COULD RUN YOU OFF THE ROAD AND GAS LEAK BLOW UP YOUR CAR. MY GUESS IS THESE PARTS ARE MADE IN CHINA. WE ALL HAVE TO PAY FOR THIS WITH OUR SAFETY AND OUR LIVES IN SOME CASES.
WHILE TURNING TO PARK THE ENGINE THROTTLE SUDDENLY ACCELERATED & JEEP JUMPED THE CURB, CRASHED THRU A FENCE & ENDED UP IN THE OCEAN. WE WERE RESCUED BY DANA POINT HARBOR PATROL.
THE VEHICLE POWER ABRUPTLY DROPS WHILE DRIVING LOSING ANYWHERE FROM 100 TO 500 RPMS. IF THE VEHICLE IS STOPPED AT A SIGNAL OR TRAVELING AT LOWER SPEEDS THE POWER DROP WILL SHUT DOWN THE VEHICLE. THE PROBLEM IS RANDOM AND VERY UNSAFE
WHILE BEING TOWED BY OUR RV ON A CITY STREET, A FIRE STARTED UNDER THE HOOD OF THE JEEP. THE TRANSFER CASE WAS IN NEUTRAL. THE MANUAL TRANSMISSION WAS IN NEUTRAL. THE IGNITION SWITCH WAS TURNED 1 NOTCH TO ACCESSORY TO UNLOCK THE STEERING. THE FIRE WAS EXTINGUISHED BY THE FIRE DEPARTMENT. NO POLICE REPORT WAS FILED BECAUSE THE FIRE WAS NOT CAUSED BY AN ACCIDENT. BECAUSE OF THE SEVERITY OF THE FIRE DAMAGE, NO CAUSE OF THE FIRE WAS DETERMINED.
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!!!
Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
