I own a 2005 Jeep wrangler. When filling up the vehicle with gasoline it often doesn't register the fact that the tank is full and the gas comes pouring out. The gas leaks onto me, my Jeep and the ground. This happens every time I fill my tank. I see this as a safety issue since it's bad to get gasoline on your body/clothing, it's also damaged the paint on my Jeep in that area and the spillage on…

What stands out
Fuel system accounts for 53% of every owner complaint on file for this vehicle — the dominant problem area across 12 categories tracked.
Owners have filed 347 fuel system complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
The failure pattern owners describe
The dominant complaint across these 50 narratives is fuel spilling from the filler neck during and immediately after refueling. Owners consistently describe the pump shutting off at full tank, then fuel gushing, spraying, or splashing back out onto the vehicle, ground, and whoever is holding the nozzle. The spillage volume ranges from a few ounces to over a quart per fillup, and it happens nearly every time the tank is refueled, regardless of pump speed, nozzle position, gas station brand, or geography.
Most owners and mechanics attribute this to a faulty check valve (rollover or fuel filler valve) inside the tank that fails to seal properly, allowing fuel to backflow when internal pressure equalizes. The defect emerges unpredictably between 20,000 and 75,000 miles—sometimes from the first fillup, sometimes after years of normal operation. Owners note they've tried different pumps, different stations, slow filling, and nozzle angles; nothing prevents the spill.
Dealers uniformly recommend full fuel-tank replacement at $500–$1,200. However, some owners report replacement tanks fail with the same symptoms after only 20,000 miles. Chrysler voluntarily extended warranty coverage and tank replacement for 2007–2008 Wranglers following an NHTSA investigation, but declined to expand the program to 2004–2006 models experiencing identical failures. Owners consider this a fire and environmental hazard that warrants recall; Chrysler has not issued one.

Failure modes owners describe
Fuel spilling from filler tube during and after refueling
When the pump shuts off at full tank, fuel spews, splashes, or gushes out of the filler neck onto the vehicle, ground, and person refueling. Owners report 8 oz to over a quart of fuel lost per fillup.
When: Occurs from early ownership (20K–30K miles) through higher mileage (75K–85K miles); some occur from first fillup
Symptoms owners cite: Fuel spits back out approximately 0.5–1 second after pump shuts off; Violent spray or splash of gasoline from filler opening; Fuel puddles 24+ inches in diameter on ground; Gasoline on operator's hands, arms, clothing, and vehicle fender; Occurs regardless of pump speed, nozzle angle, gas station brand, or geography; Sometimes occurs even when filling slowly or stopping before 'full'
Repairs/costs cited: Dealerships recommend full fuel tank replacement, cited cost ~$500–$1,200. Some owners report replacement tanks fail again after ~20K miles. One owner replaced filler neck only; problem persisted.
Recalls/TSBs owners mention: NHTSA investigation PE10-032 of 2007–2008 Wranglers led Chrysler to voluntarily extend warranty/replace tanks for those model years only. Older (2004–2006) models excluded. Dealer claims reported as 'normal wear item' or 'common problem' but refused warranty coverage on out-of-warranty vehicles. Some dealers unable to duplicate issue.
Faulty check valve or rollover valve in fuel tank
Multiple owners and mechanics attribute fuel spillage to a defective check valve (rollover/fuel filler valve) inside the tank that fails to seal properly, allowing fuel to surge back when pressure equalizes at the end of refueling.
When: Typically emerges around 20K–40K miles; can manifest at any point depending on valve degradation
Symptoms owners cite: Fuel backflow after pump shutoff; Air pocket rushes from tank toward filler when pump stops; Pressure imbalance in tank allows fuel surge; Non-ethanol-resistant plastics swell and jam valve (per one owner's research)
Repairs/costs cited: No individual valve replacement offered; dealers state entire fuel tank must be replaced (~$500–$1,200). One owner reports dealership suggested fuel tank replacement after smoke test revealed evap leak; fuel hoses replaced but spillage continued.
Recalls/TSBs owners mention: Chrysler acknowledges problem on some 2007–2008 models via extended warranty program but refuses recall. No manufacturer statement in narratives regarding 2004–2006 or 2005 models specifically.
Vapor vent or fuel system venting defect
Tank fails to vent properly during refueling, creating a pressure buildup that causes fuel to spray back after the pump shuts off. One owner notes tank isn't venting correctly; another identifies an inner tube extending into tank that creates air imbalance.
When: Varies; some owners report onset around 40K–75K miles, others from purchase
Symptoms owners cite: Insufficient venting during refueling; Pressure buildup as tank nears full; Fuel surge after pump shuts off; One owner describes inner tube design in pressure-equalization system as flawed
Codes mentioned: Possible EVAP system codes mentioned by one owner (check engine light at ~55K miles)
Repairs/costs cited: One owner had fuel hoses replaced following smoke test for EVAP leak, but spillage persisted. Another replaced filler neck; problem continued.
Recalls/TSBs owners mention: No specific OEM recall or TSB cited in narratives for 2005 models. One owner received software upgrade to fuel system on 4/6/12 without success.
Oil pump drive assembly screeching (unrelated to fuel system)
Loud screeching from oil pump drive linked to seized bushing at cam position sensor/oil pump drive due to inadequate lubrication; drive gear and camshaft gear self-destruct, causing loss of oil pressure.
When: Observed shortly after purchase; Dodge campaign E05 (March 2005) applied only to engines built 10/20/2004–2/1/2005
Symptoms owners cite: Loud screeching noise from oil pump drive assembly during startup; Noise subsides as engine warms but continues to recur; Drive gear and cam gear destroyed
Repairs/costs cited: Requires engine tear-down; estimated rebuild cost ~$4,000. One owner replaced drive gears and cams.
Recalls/TSBs owners mention: Dodge campaign E05 issued March 2005; limited to vehicles built 10/20/2004–2/1/2005. One owner's October 9, 2004 build date fell outside window and was deemed ineligible despite matching failure.

After having my Jeep for 3 1/2 years, every time I fill up my gas tank (no matter what gas station) the automatic shut off does not work on the pump and large amounts of gas spill out everywhere. It did not do this for the first 3 1/2 years of owning the vehicle. Numerous other people on the internet are experiencing the same issue and it's believed to be the roll over check valve in the…
When filling the fuel tank on my 2005 Jeep wrangler, the tank 'spits' the fuel out of the filler neck as it nears the top. The problem started just recently. But the amount of fuel spilled is getting larger with each fill up. *tr
When I try to fill my tank using the autofill option on the fuel pump handle, the fuel doesn't shut off when the tank is full and will come splashing out in force. My solution thus far is to be aware of the gallon amount as I fuel the vehicle, then when it gets fairly close, I try to trickle the fuel in so as not to splash too much fuel out on to the ground or my pants and shoes. *kb
When filling the fuel tank with gas, the gas pump does not shut off when the tank is full. This causes overflow of gas from the tank. An internet search indicates that this is a common issue with Jeep wranglers. *tr
Tl*the contact owns a 2005 Jeep wrangler. The contact stated that the locking mechanism on the gas cap failed and she was unable to put fuel into her vehicle. The dealer replaced the gas cap, but the failure recurred a year later. As of december 28, 2007, the dealer had not repaired the vehicle. The failure mileage was 5,000 and current mileage was 16,000.

I traced a loud screeching noise to the oil pump drive assembly. As the engine warmed up the noise subsided but continues to occur.on line research shows this to be a common problem for the 05-06 wranglers due to a design change from 04 to 05 model years where a bushing at the top of the cam position sensor/oil pump drive that seizes due to lack of lubrication and causes the drive gear on the oil…
Just purchased this used Jeep wrangler unlimited rubicon about 2 1/2 months ago and everytime I fill the gas tank, fuel pukes back out the filler opening and runs down the side all over the ground before the gas pump can shut off. Seems really dangerous not to mention making a big, embarrassing mess. It does not matter where I refuel, happens at all gas stations. *tr
