The check-valve nipple on the gas tank of my 2011 Jeep Wrangler is broken. You can see it and smell the gas vapors leaking from this nipple. The vehicle has 86K miles. The Jeep failed our Delaware state inspection because the check engine light came on. The Jeep smells like gas and in addition to harmful vapors, it is a serious safety issue and an explosion danger. Two service stations attempted to fix this without success. The error code is P0455 for an emissions leak. The most recent service station ordered several previously-owned Jeep gas tanks but they all had this same failure. They next ordered a new gas tank from Jeep which was out of stock for several months, indicating they can not keep up with the demand for these failing nipples. When the new gas tank finally came in, this same nipple was broken and this was a brand new gas tank. If you go on line, you will see this is a common problem and a safety issue. As a former engineer for Ford Motor Company, it is clear Jeep has a design flaw that will break and cause a safety risk to customers. The material is wrong for this application, and there is not enough strain relief where this nipple is located. It will inevitably break on all Jeeps at some point in time causing this safety risk. I told the service station that there is no reason to replace the gas tank because this nipple will simply fail again. They have other Jeeps they are working on with this same problem so had no problem canceling my service request. Please address this problem with Jeep before someone is injured or killed.
Jeep wranglers have a common problem with the fuel inlet. It clogs over time then will cause fuel to spill over or click off constantly while fueling the vehicle. This gets worse in cold months. I have spilled fuel hundreds of times over the years while fueling. Jeep forums and YouTube talk about the widespread issue. No warranty or recall? Perhaps after a gas station goes up in flames
The contact owns a 2011 Jeep Wrangler. The contact stated that the fuel pump would continuously stop while attempting to refuel the vehicle. Due to the failure, the contact could not gauge when the fuel tank was full; therefore, fuel would splash out of the tank once it reached capacity. The contact stated that fuel would splash onto her clothing or onto her face because of the failure. The contact called a dealer and the service mechanic confirmed that the failure was common and that her fuel tank would need to be replaced. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 142,000.
WHEN FILLING UP WITH FUEL, THE GAS WILL SPIT BACK AND SPILL FUEL ON THE SIDE OF JEEP AND GROUND, EVEN AFTER THE AUTOMATIC SHUT OFF OF THE HOSE ENGAGES.

WHEN FILLING WITH FUEL, GAS WILL SPIT BACK FROM THE FILLER NECK AND ALL OVER THE SIDE OF THE JEEP RIGHT BEFORE THE FUEL NOZZLE CLICKS OFF. THIS HAS HAPPENED 3 TIMES NOW IN THE 3 WEEKS SINCE I BOUGHT THIS VEHICLE FROM A DEALER. THIS CREATES A FIRE HAZARD IN THE EVENT GAS HIT A HOT SPOT OR A SPARK CAUSED BY STATIC, ETC...
WHEN FILLING UP AT A FUEL PUMP, THE FUEL PUMP HANDLE WILL CLICK OFF AND AFTER THAT HAPPENS, ABOUT 1/4 OF A GALLON OF FUEL WILL SPILL OUT OF THE FILLER NECK ONTO THE SIDE OF MY VEHICLE.

I HAVE SPILLED GASOLINE, ON VEHICLE, CLOTHING, GROUND, GAS PUMP, ETC. THIS IS A PRETTY SERIOUS ISSUE AND I COULD NOT FIND A RECALL. I DON'T THINK THIS SHOULD BE IGNORED. I HAD TO ADD A DATE BELOW, JUST THE LATEST TIME IT HAS BEEN AN ISSUE. IT HAS OCCURRED MULTIPLE TIMES TO MYSELF AND MY SPOUSE.
CRACK IN GAS TANK - THE CHECK ENGINE LIGHT ILLUMINATED YESTERDAY WHEN I STARTED THE VEHICLE. I TOOK MY VEHICLE TO MY MECHANIC. THERE IS A CRACK IN THE TOP OF THE GAS TANK. MY MECHANIC SAID THAT AFTER RESEARCH IN TRYING TO GET A NEW GAS TANK, HE FOUND THAT THIS IS AN ISSUE. MOPAR HAS A SIGNIFICANT BACKORDER FOR THESE TANKS. THIS IS DEFINITELY A SAFETY ISSUE AND I HOPE IT WILL BE LOOKED INTO.
