Wrangler 4WD 6-cyl

  • 50,683 miles


Just purchased a 2006 Jeep Wrangler sport. All stock. When fueling the vehicle, once the fuel is almost full or to the point of full, the fuel shoots out of the fuel inlet. Also, it does not trip the fuel shut off on the dispenser quick enough.

Wrangler 4WD 6-cyl

  • 25,000 miles
My 2006 Jeep Wrangler has developed a consistent failure to stop pumps at gas stations from continuing to pump fuel even though the tank is full. As a result, gasoline is spat out from the filler neck of the gas tank like a burst from a fountain, splashing out on the ground, on the side of the vehicle, and generally on me, the operator of the gas pump. It started about a year ago, and it now exhibits this behavior consistently every time I fill up. This is a problem not only due to the cumulative environmental impact of spilling out raw gasoline and of ruining clothing and resulting in carrying with me the strong smell of gasoline all day at work and at home, but it is also a clear and appalling safety hazard with raw gasoline splashed around. The Jeep dealership has recommended a very costly replacement of the entire gas tank assembly at my own expense and has said that this will only temporarily relieve the symptoms, that the design has not changed and thus the problem will continue to resurface.

Gasoline spill each time fuel tank is filled. At about the same time the tank reaches full and shuts off the gas flow at the nozzle a large volume of gasoline rushes out of the filler neck of the vehicle and onto the pavement. Potentially dangerous situation and quite prevalent in this model vehicle.

Every time I fill my fuel tank without metering the fuel the last gallon, the shut-off valve fails and fuel pours out of the filler neck onto the ground, Jeep, and myself if I'm close enough.

Multiple instances of gas tank in my 2006 Jeep Wrangler unlimited overflowing, due to possible check valve malfunction and/or improper design from factory. When filling ones gas tank, you would expect the pump to stop once the tank has reached its capacity. However due to a faulty in-tank check valve, the pump never gets the pressure change as a signal to stop the flow. Hence, every time I fill up I end up spilling a not-insignificant amount of fuel on the ground. This issue is absolutely not operator error, it is a known defect by Jeep/Chrysler.

The gas spills out everytime I fill up. The pump does not click off until gas sprays out of the filler neck. It is not the gas pump because this is an ongoing problem and I fill up and may different places.

Fuel spews from fuel tank during fill up. Fuel nozzle would shut off normally until recently it has now become a problem. This should not happen and this problem is potentially very dangerous to not only myself but to others sharing adjacent pumps not to mention the environment.

While fueling vehicle at gas station, fuel splashes out before fuel pump shuts off at fill up. Regardless of gas station or speed at which pump is set at fuel always spills unto vehicle and ground. It is apparent that the fuel tank's roll over check valve is at fault.

2006 Jeep Wrangler rubicon - during every fueling the fuel tank will overflow, this allows gas to run on the ground and on my person if standing too close to the vehicle.

When I attempt to fill my gas tank, the gas comes back out of the tank. I have tried this by going slow & when the gas shuts off, I shake the Jeep to get the air out of the tank - when I do this the air pocket pushes gas back out of the tank even when I don't have the fuel nozzle still in the tank. This isn't the first time that this has happened - I purchased the Jeep in St. Augustine, fl in Jan., 2011 & I had to get gas right after purchasing it. The first time I had the auto shut-off on the gas filler - it clicked off & gas started flowing back out of the tank. At first I thought that the gas filler nozzle was defective, & notified the convenience store about the overflow - I asked for some "dry agent" to capture the gas that had spilled over. The attendant shut the pump station down, & said they would call someone to check out the filler nozzle. The next time that I needed gas (back in orlando, fl) the Jeep was back near empty (fuel light "on"). I used the auto click-off on the filler - same[xxx], different day! I heard the "click" of the auto-shut off & within a second, gas was pouring back out of the fuel neck of the Jeep. People who were pumping their own gas heard the fuel come out of the tank (and heard me curse, lol!) they couldn't believe what they saw. I'm not sure how much fuel poured back out of the fuel neck of the Jeep (and the tank for that matter), but there was a pool of fuel on the ground. I notified the fuel attendant of the situation & they didn't have any dry-sorb chemical to absorb the fuel. I used paper towels to clean it up. Now I have to resort to fill the Jeep with no more than 12 gallons (no more shaking or the fuel may come back out). I've been told that the internal valve is defective or that the use of ethanol in the Jeep has destroyed the internal valve. I don't give a [xxx] what has caused it - this is a dangerous situation that needs to be resolved. There are thousands of Jeep that have the same problem - do your job NHTSA.gov!!! information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

Over flow of gasoline every time I fill up at the gas station. It has been an issue since I bought my Jeep brand new in 2006. The gas station attendant holds you responsible for all gasoline and expects it to be cleaned. I drive a 2006 Jeep Wrangler X.

During re-fueling my 2006 Jeep Wrangler, fuel will come back out of the inlet when the fuel level reaches the top. It spills no matter how slow or fast I fuel the vehicle. I have been reading on internet community sites that this is a large scale problem and that I should log a complaint.

Faulty fuel tank causes fuel spill every time tank is filled. I bought this Jeep a year ago and every single time I've filled the tank it spits back fuel when the tank is filled. I would guess 4-5 ounces of fuel get spilled on the ground every time the tank is filled. Dealership diagnosed the problem and says the tank is faulty and needs to be replaced.

When refilling my Jeep with gas it occasionally overflows. I didn't know if it was a pump or Jeep issue until I started hearing more people having the issue and realized it was a Jeep issue and not a pump issue. I understand that the 2007-2008S have a tsb and djc will fix for free, but my Jeep is a 2006 and has this problem and I am not covered. I would like the tsb to include all Jeep.

It seems a check valve that is part of the fuel tank failed. Regardless of gas station, nozzle position or flow rate I always get gas splash back when I fill up the tank. It is my understanding that replacement gas tanks have the same defect that will cause them to fail in a short period of time.

The contact owns a 2006 Jeep Wrangler unlimited. The contact stated that after refueling the fuel tank, gasoline fuel would spill back out onto the ground. The vehicle was not inspected by a dealer nor was it repaired. The failure mileage was approximately 34,000.

My gas tank will overflow if I am not incredibly careful with the gas nozzle. This has happened repeated times and on one occasion poured gas on my shoes. (I now stand pretty far back whenever I am filling up) it has also poured down the side of the Jeep, discoloring the fender and paint, as well as leaving an approximate 1-2 foot puddle of gas on the ground at the gas station. I'd guess about 1/4 to 1/3 gallon of gas will gush out each time it overflows. To fix this (according to Chrysler) would cost between $800 and $1000. How is this in any possible way* a safety hazard"?"!
