What stands out
No new NHTSA fuel system complaint has been filed on this vehicle in over 11 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.

full bulletin at NHTSA ↗Part Description: RHR Radio Issue Description: Issue 1: While performing RHR radio reflash (software update), on rare occasions, the flash can fail to properly update the radio resulting in the radio running in Emergency IFS mode. This error condition can occur due to interrupting the software update, background radio operations interfering with the reflash process, etc. The radio will reboot, but with limited functionality (examples may include but are not limited to: NAV, Voice Recognition, Bluetooth, or AUX jack are inop, no available space shown on HDD, etc.). The radio can still be properly updated by simply reinserting the software update disc and performing the reflash procedure again

The failure pattern owners describe
Owners report the dominant complaint is fuel overflow during refueling. Nine of twelve narratives cite the pump failing to cut off automatically when the tank is full, or fuel backing up out of the fill neck after the pump stops. Spillage ranges from a splash to about one-half gallon, occurring at all gas stations and with different pump types. Several owners have tried manual pump control and different filling strategies without success. One owner at 142,000 miles was told by the dealer that the problem is common and the fuel tank requires replacement. Two owners note that a TSB was issued for 2007/2008 Wranglers to address this identical failure, but no recall covers the 2011 model year. Dealerships refuse warranty coverage because no recall applies.
One unrelated narrative describes a fire in the engine compartment traced to hot transmission oil leaking from the fill tube onto the engine, causing damage to the wiring harness, fuel lines, and plastics. Chrysler denied any manufacturing defect after investigation and refused repair support, leaving the owner with $5,000 in insurance-estimated damage.
One owner reported gasoline odor in the cabin during high-altitude, hot-weather 4WD use; the dealer could not identify the cause.

Failure modes owners describe
Fuel pump fails to shut off at full tank
The fuel pump does not automatically stop when the tank reaches capacity, allowing fuel to overflow out of the fill neck and onto the vehicle and ground. Occurs regardless of pump type (automatic or manual), filling rate, or gas station.
When: During refueling; up to 142,000 miles noted in one complaint
Symptoms owners cite: Fuel overflows/spills out of fill neck when tank is full; Fuel splashes onto driver or clothing; Unable to reliably fill tank to full capacity; Fuel spills approximately one-half gallon or more; Problem occurs at all gas stations with different pumps
Repairs/costs cited: Fuel tank replacement required. One owner reported dealer quoted cost; insurance estimated repair at $5,000 for fire damage related case. Dealers refuse warranty coverage citing lack of recall for 2011 model year.
Recalls/TSBs owners mention: TSB exists for 2007/2008 Wranglers for tank replacement per owner complaint. No recall issued for 2011 model. Chrysler declined to cover repair in fire case, stating investigation found no manufacturing defect.
Fuel tank overflow at fill nozzle
Fuel surges or backs out of the fill neck after the pump shuts off, or overflows continuously regardless of automatic shutoff operation. Occurs across multiple gas stations and pump types.
When: Consistent issue since purchase; mileage not specifically noted except one instance at 142,000 miles
Symptoms owners cite: Fuel spits or shoots out after pump stops; Fuel backs up and spills onto vehicle exterior and ground; Fuel splash hazard to driver and passengers; Overflow occurs even when using low-flow filling techniques
Repairs/costs cited: Owner reports fuel tank replacement is only solution. Dealership confirmed this is a common failure. No specific repair costs cited for this mode alone.

Engine compartment fire from transmission oil leak
Hot transmission oil leaked onto the engine and surrounding components, igniting a fire in the engine compartment. Caused damage to wiring harness, fuel system lines, and plastic components.

What owners are reporting 1 most recent
Whenever I go to the gas station to fill up with gas, one of two things happens; either it doesn't automatically cutoff and gas spills out onto my fender/wheel, or it does the opposite....continues to click off over and over and over again and I am unable to fill my tank. I have tried getting gas at several different stations now, and it does it at all of them. *tr
