What stands out
Owners have filed 95 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 14 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
Every fill-up becomes a hazard. Owners describe gas gushing, burping, or splashing back out of the filler neck as soon as the pump nozzle shuts off or near full capacity. It happens at every gas station, regardless of fuel type, pump speed, or how slowly the nozzle grip is operated. Gas sprays onto the person refueling, the vehicle exterior, and the ground around the pump. Multiple owners report this began between 8,000 and 74,000 miles, with most starting between 19,000 and 55,000 miles, and it recurs every single refueling after onset.
Owners note they cannot avoid it by slowing the pump or stopping before "full"—gas erupts even at low flow rates or when the pump shuts off automatically on its own. The overflow volume runs from ounces to several cups. Interior cabin odor and gasoline-soaked clothing cause headaches and breathing complaints. One owner reported a spouse experienced headaches and stomach pain for months from fume exposure.
Dealers tell owners the entire fuel tank must be replaced at $730–$800 cost. Some dealers recommended replacing the filler neck or fuel vapor filter without resolution. One complaint documents a dealer finding a deteriorated vacuum hose and attributing cabin odor to that rather than the tank defect. One owner reports a dealer could not locate any problem despite thorough inspection. Several complaints note Chrysler has a TSB (technical service bulletin) for 2007–2008 Wranglers covering a nearly identical issue and issued a recall for those models, but has not extended the same remedy to the Liberty. Some owners report Chrysler offered partial cost coverage via case numbers; others report denial of responsibility or claims that no defect exists.

Failure modes owners describe
Fuel tank overflow during refueling
Gas spews, burps, or splashes back out of the filler neck when the pump nozzle shuts off or near tank-full capacity. Occurs at all gas stations regardless of fuel type, pump speed, or nozzle grip method. Gas sprays onto vehicle exterior, ground, and person refueling.
When: Most commonly reported between 19,000–74,000 miles; some cases early (8,000–20,000 miles), others later (43,000–74,000 miles). Occurs every refueling event once started.
Symptoms owners cite: Gasoline gushes, burps, or spews out of filler neck when pump nozzle shuts off; Gas sprays onto clothes, hands, feet, vehicle, and ground; Occurs at multiple gas stations and with different pump types; Happens whether nozzle shuts off automatically or manually; Happens regardless of fuel type (premium, regular, ethanol or no-ethanol); Happens regardless of pump flow rate (fast or slow); Interior and clothing smell of gasoline; occupants report headaches
Codes mentioned: P0440 (evaporative emission control system malfunction), Check engine light, Gas cap warning light
Repairs/costs cited: Dealers recommend replacing entire fuel tank (reported cost $730–$800). One complaint reports dealer replaced filler neck with integrated sensor but overflow persisted. One complaint indicates dealer could not locate problem despite multiple inspections. One complaint reports owner attempted fuel vapor filter replacement without resolution before tank replacement was recommended.
Recalls/TSBs owners mention: Some owners report Chrysler/Jeep acknowledged problem via case numbers and offered 50% cost coverage; others report Jeep denied responsibility or claimed no problem exists. TSB acknowledged for 2007–2008 Wranglers with similar issue, but not issued for Liberty. 2007–2008 Wrangler recall existed but Liberty was not included. Some dealers stated problem is not under warranty once vehicle age/mileage exceeded coverage.
Fuel vapors entering cabin
Strong gasoline smell inside vehicle cabin during and after refueling overflow events. In one case, deteriorated vacuum hose was found that allowed fuel fumes into cabin; dealer attributed symptom to that hose rather than tank defect to avoid warranty repair.
When: Occurs during and for hours after refueling; one complaint notes wife experienced symptoms for months prior to discovery of abraded vacuum hose.
Symptoms owners cite: Strong smell of gasoline inside vehicle cabin; Smell lingers for couple of hours after overflow incident; Wife reported headaches and stomach pain for months in one case; Occupants report headaches and breathing problems from fume exposure
Codes mentioned: Check engine light
Repairs/costs cited: One dealer identified deteriorated/abraded vacuum hose as potential source. Whether this is a secondary effect of fuel system failure or independent defect is unclear from narratives.
Recalls/TSBs owners mention: One dealership (Alexander Chrysler Jeep, Franklin, TN) attempted to attribute cabin odor to vacuum hose defect to avoid warranty repair; owner complained this left wife breathing toxic fumes for months.
Stalling after refueling
Vehicle stalls immediately after driving away from gas pump, at traffic lights, or in intersections following refueling. Difficult restart for approximately 1 minute after stall.
When: Occurs after refueling with fuel tank full or recently filled.
Symptoms owners cite: Vehicle stalls after leaving gas pump; Stalling occurs in traffic, at red lights, and in intersections; Engine hesitant to restart; takes approximately 1 minute to restart

When filling up at a gas station, the gas tank over flows before the pump stops. I originally thought it was a broken pump, however, I have now filled up over 4 times at 4 different gas stations and the problem continues to happen. This most recent time I have lost around 1/2 gallon of gas on the ground. I am also concerned with the effect of the gas on my paint/car body. *tr

It's a documented issue but not catastrophic. 95 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 81 complaints that reported odometer mileage, most fuel system failures cluster between 26,000 and 45,375 miles, with the median around 37,000. A quarter of owners report trouble before 26,000; a quarter make it past 45,375. 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.
