1 Tank Mounting problem

Failure Date: 12/26/2011

When filling tank, just prior to the pump auto shutoff, fuel sprays out of the gas tank, sprayed all over me and ran out all down my vehicles side. This has happened to me the last 3 times I have filled my tank and is very dangerous. The total amount of fuel that sprays out is approximately 1/16th to 1/8th of a gallon.

2 Tank Mounting problem

Failure Date: 01/13/2011

When filling gas tank a large backsplash of gas comes out as tank approaches full. I tried adjusting the gas hose nosle both in and out. Splashing occurs in all cases. Gets less the further the nossel is pulled out. Gas could splash on person standing close, mostly runs down side of Jeep and onto and over rear bumper and onto ground. Service station attendants have come out to check for issue due to amount of gas spilled. Car had no issues with this for first 3 years. Problem developed suddenly with no warning. Only fix is to not completely fill tank but you have to guess each time how close to full the tank is. Gas spilled out between 1/10 and 1/2 gal each time -hard to measure.

3 Tank Mounting problem

Failure Date: 01/11/2011

Gas will spill from the fuel inlet when filling the gas tank, regardless of speed of additional gas or current amount within gas tank. Enough gas is spilled to cause significant damage should it reach an ignition source.

4 Tank Mounting problem

Failure Date: 11/20/2010

2008 Jeep Wrangler unlimited having fuel spew from filler pipe when filling tank. This occurs just as tank is full and fuel pump automatically stops. The amount of fuel spilled is about 500 cc and comes out as a bubbly mixture. The fuel spills on the vehicle and on to the ground. It will get on the person filling if standing close. The problems started at about 37k miles and is now occurring with nearly every fill-up. There is no warning that this is going to happen that would allow one to stop the pump before the overflow occurs.

5 Tank Mounting problem

Failure Date: 10/20/2010

I own a 2008 Jeep Wrangler where fuel spills out of the filler port during the refueling process. This condition occurs when the fuel tank is filled to the full or nearly full level and the gas pump automatically shuts or clicks off. This occurs every time I fill up with gas, and every time it happens, a significant amount of gasoline is splashed all over the driver side rear corner of the vehicle, the ground, and sometimes the person filling the tank. It first happened roughly 600 miles after the bumper to bumper warranty expired, so the dealership currently will not cover the repair.

6 Tank Mounting problem

Failure Date: 10/15/2010

Fuel tank overflows a large amount of gas whenever I fill the tank. I estimate approximately 6 -10 ounces is spilled down the body and onto the ground every time I attempt to fill it up. Will overflow even when I fill it slowly. Started happening at approx 37,000 miles. Happens at all gas stations.

7 Tank Mounting problem

Failure Date: 10/01/2010

Vehicle spills fairly large amount of gas when filing gas tank constantly. Gas spills on vehicle, ground and person which could be a fire and environmental hazard. Took it to the dealer and they claimed to have changed the filler neck but the problem continues.

8 Tank Mounting problem

Failure Date: 09/23/2010

I have a 2008 Jeep Wrangler unlimited that overflows while filling up the gas tank. The dealership changed out the filler neck and the problem when away for a few months but it is back. Everytime (without fail) the tank is filled up a considerable amount of gas pours back out.

9 Tank Mounting problem

Failure Date: 09/04/2010

During the first week of September 2010, when refueling my 2008 Jeep Wrangler unlimited, when the gas station fuel pump /nozzle automatically shuts off, fuel began to overflow / backflow and spill out onto the side of the Jeep and the ground. This continued to happen almost everytime I refueled. I began stopping the fuel nozzle manually when it sounded like the fuel was getting close to the nozzle. It would still overflow on occasion. Now I have to refill the Jeep's gas tank judging by how low the gas gauge reads and how many gallons I put in. Usually I fill the gas tank a to little over three quarters of a tank. I do not feel comfortable filling up the gas tank until it is full or filling it until the pump automatically shuts off when it sense the tank is full because the amount of overflow varied, but in worst cases I estimated it was anywhere from 10 fluid ounces to 32 fluid ounces which really concerns me. There were times when the gas literally gushed out enough to splash onto the thigh area of my pant leg and shoes, while I was standing a good 18 inches from the Jeep.

10 Tank Mounting problem

Failure Date: 08/10/2010

I have a 2008 Jeep Wrangler. Each time I refuel the gas tank it spews gasoline on me as well as the vehicle and the ground. This is a fairly large amount and must be a fire safety as well as a health hazard from direct skin contact. I purchased this vehicle from the dealership used and under warranty approximately 8 months ago. This problem started about 2 1/2 months ago after warranty expired. I am taking vehicle back to dealership along with a printout of the complaints already voiced of the same nature since this appears to be a ongoing problem with these vehicles.

11 Tank Mounting problem

Failure Date: 05/18/2010

When filling up my 2008 Wrangler rubicon unlimited with fuel, it does not allow any pump to automatically shut off on time therefore it causes a good amount of fuel to spill out every time. No matter how fast or slow you are pumping. This could make for a dangerous situation as well as have a bunch of fuel spills which cant be good in the eyes of the epa. Seems to be a very common problem with several late model Wranglers as evident by personal experience and many, many post on Jeep Wrangler forums. Took it to the dealership, and of course they couldn't replicate the problem so they couldn't fix it. From what I've read on forums it seems that the only fix is to change out the fuel tank, which apparently has a faulty valve inside. This issue has been going on for quite some time. I bought the vehicle new and it currently only has 13,400 miles. Some people have reported them doing this in the very first fill on their new vehicles.

12 Tank Mounting problem

Failure Date: 09/20/2009

Stopped at gas station to fill up tank. Held down the handle until the tank was full and the pump is supposed to cut off. It worked correctly. However, immediately after it cut off, gas spewed back up out of the gas tank. It was enough to spill out onto the side of the vehicle and the ground below. I would estimate the amount that spilled out was about a 1/4 of a gallon. I bought the vehicle used in July with about 35,000 miles. The first few refills did not do this. It has happened on approx. The last three refills in a row at three different gas stations. Do not have a cause or solution. There are several others with the same vehicle with the same problem starting to occur. .

13 Tank Mounting problem

Failure Date: 04/01/2009

My 2008 Jeep Wrangler x's gas tank overflows upon the last bit of filling the tank. It started at about 20,000 mi. The gas pump shuts off, and then wait a few seconds to hear it coming up the throat of the tank and it spills a good amount of gas everywhere, not just a few drops. There were no particular events leading up to the failure, and it occurs 9/10 times that I get gas. It does not matter which gas station I go to, or what pump is being used. Chrysler told me when I brought the Jeep into the Jeep service department that "they have no solution for the problem".

14 Tank Mounting problem

Failure Date: 01/31/2008

Every time I fill the tank on my 2008 Jeep Wrangler a significant amount of fuel overlows out of the tank. This is a serious health and safety issue. This problem occurs when I fill the tank myself or when an attendant fills it. I have been told by the attendant at my local station that this is common to this make and model.

15 Tank Mounting problem

Failure Date: 01/01/2008

When fuel tank is filled, as soon as the fuel pump nozzle "clicks" off (indicating the gas tank is full, several ounces of gasoline "spits" out. It spits out in a fashion to directly land on the shoes and/or pants leg of the person operating the fuel pump. This occurs on the first click (as opposed to those situations that occur when someone is "topping off" the gas tank). It occurs on every fuel tank fillup, except in those situations where the gas pump operates notably slower than most service stations. The amount of gasoline that ends up on the ground is typically at least 2 or more feet in diameter. The dealer has acknowledged that these fuel tanks do not vent properly and that caused the problem. Many you tube videos demonstrating the problem. Environmental - raw gasoline dispensed on the ground personal - raw gasoline on clothing/skin, with issues of strong gasoline odor in passenger compartment safety - potential disasterous issues if spark were to occur.
