What stands out
Owners have filed 188 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.
No new NHTSA fuel system complaint has been filed on this vehicle in over 15 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering fuel system on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The overwhelming complaint cluster—affecting the vast majority of these 188 reports—centers on fuel spilling from the filler neck during refueling. Owners consistently describe the pump clicking off, followed by gasoline shooting, spurting, or flowing forcefully out of the fill tube and down the vehicle's side, often soaking the ground, bumper, and the person pumping fuel. Spillage ranges from a few tablespoons to two quarts per incident. This occurs at every fill-up or nearly every fill-up, regardless of gas station, nozzle angle, or whether the owner uses manual or automatic shutoff. The defect typically emerges between 20,000 and 40,000 miles—well after the vehicle leaves the showroom—though one owner reported it at 16 miles.
A smaller number describe actual fuel leaks from tank body or fuel lines. One owner discovered a pinhole in a plastic fuel-line elbow under the driver seat spraying fuel onto the undercarriage—a dangerous condition if fuel contacted hot surfaces.
One critical narrative reports a fuel-tank explosion and fire during normal driving, with damage to fuel lines and firewall; the Chrysler investigation team declined to examine the fuel lines.
A few owners also report a burning rubber or chemical fuel smell with occasional starting failures, unresolved by dealer cleaning.
Chrysler's recall covered 2007–2008 Wranglers built between March 2007 and March 2008, but many affected vehicles fall outside this window—owners cite build dates in May 2008, June 2008, and later. Repair typically involves fuel-tank replacement; one owner cited an eight-month parts backorder.

Failure modes owners describe
Fuel overflow during fill-up due to defective fill-valve or check valve
Gasoline spills out of the filler neck after the pump clicks off, often forcefully. Occurs at various fuel stations regardless of nozzle angle, grip, or manual vs. automatic shutoff use. Spillage volume ranges from a few ounces to 2 quarts per incident. Problem begins mid-life (typically 20,000–40,000 miles) rather than at new; owners report it was absent when vehicles were new.
When: 20,000–40,000 miles; several owners report onset at 6 months to 2.5 years after purchase; one narrative mentions 16 miles at failure, current at 26,000
Symptoms owners cite: Gasoline spills from filler neck after pump auto-shutoff clicks; Occurs every time or nearly every time tank is filled; Fuel shoots, sprays, or flows down side of vehicle and onto ground; Spillage volume 1 tablespoon to 2 quarts per incident; Sometimes fuel runs into exhaust or underneath vehicle; Problem did not exist when vehicle was new
Repairs/costs cited: Fuel tank replacement reported by multiple owners; one narrative mentions filler neck and fuel valve replacement; one owner paid $120 for diagnosis without repair; dealer backorder delays cited for parts (8 months)
Recalls/TSBs owners mention: Jeep recall for 2007–2008 Wranglers manufactured March 2007–March 2008 covering fill-valve overflow issue; extended warranty offered for vehicles in that range; Chrysler investigation team declined to inspect fuel lines in at least one fire case; manufacturer advised one owner there was no solution
Fuel tank crack or pinhole leak
Abnormal fuel leakage from tank body rather than fill port. One narrative documents a pinhole in a plastic fuel-line elbow under driver seat (right-hand-drive postal Jeep) squirting fuel onto vehicle underside, creating fire hazard if fuel reaches hot surfaces. Another narrative mentions confirmed fuel tank crack diagnosed by private mechanic.
When: Pinhole leak narrative: after fuel tank recall replacement (10-19-11); tank crack narrative: 43,000 miles
Symptoms owners cite: Raw gas smell inside and outside vehicle; Fine stream or leak of fuel from fuel line or tank body; Fuel leaking onto undercarriage; Tank overflow and inability to fill tank beyond half capacity
Repairs/costs cited: Pinhole elbow required replacement; private mechanic performed diagnostic confirming tank crack; manufacturer waiting list with unavailable parts cited
Recalls/TSBs owners mention: Recall-related fuel tank replacement performed in one case; no manufacturer assistance offered after warranty expiration in crack case
Burning rubber or chemical fuel smell with starting issues
Burning rubber or chemical fuel odor from vents (even with A/C off) accompanied by intermittent start failures. Dealer cleaned and sprayed vents without resolution. No diagnostic codes found despite dealer inspection.
When: 30,000–44,000 miles range
Symptoms owners cite: Burning rubber or chemical fuel-like odor from vents; Odor present even when air conditioner is off; Occasional failure to start immediately; No diagnostic trouble codes present
Repairs/costs cited: Dealer cleaned and sprayed vents; vehicle not repaired
Fuel tank explosion and fire
One severe narrative describes a loud explosion under the vehicle during acceleration that started a fire covering the undercarriage. Damage observed to fuel lines and firewall; fire department response required. Manufacturer investigation team refused to examine fuel lines.
When: May 29, 2014; vehicle mileage not specified but described as driven at 3000 RPM after traffic light
Symptoms owners cite: Loud explosion underneath vehicle; Fire covering bottom of entire vehicle; Visible damage to fuel lines and engine firewall
Repairs/costs cited: Vehicle rendered undrivable; fire department extinguished fire; no repairs performed
Recalls/TSBs owners mention: Chrysler and dealership provided no assistance; manufacturer investigation team declined to inspect fuel lines

What owners are reporting 4 most recent
Fuel overflow from filler tube and sprays onto person pumping fuel, vehicle and surrounding environment. This happen every time we fuel Jeep. We have had the Jeep since 2008 and problem started in december 2010. This Jeep looks brand new and garage kept and never been off road. *tr
Filling up at the gas station the gasoline overflows out of the tank, it happens almost every time I fill up my 2008 Jeep wrangler. *tr
Gas tank overflowed violently when the gas station automatic pump shut off.
Gas will spill out (splash) from the filler tube because the automatic fuel shutoff feature on gas pumps will not detect fuel fill level until too late. Gas will usually hemorrhage enough to splash out of the tube and run down the side of the vehicle and collect on the bumper. If you stand too close in some cases you might get gas on your clothing. This seems to be a common problem with late…

Common questions
How serious is the fuel system problem on the 2008 Jeep Wrangler?
It's a documented issue but not catastrophic. 188 complaints have been filed. Repairs average $1,200 and most owners catch it before it causes a breakdown.
At what mileage does the fuel system typically fail?
Across the 159 complaints that reported odometer mileage, most fuel system failures cluster between 24,000 and 44,000 miles, with the median around 32,241. A quarter of owners report trouble before 24,000; a quarter make it past 44,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $1,200 for fuel system repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to fuel system?
No active recalls currently cover fuel system issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
