Owner reports
Selected complaints filed with NHTSA by 2011 Jeep Wrangler owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2011 Jeep Wrangler. The contact stated that the fuel pump would continuously stop while attempting to refuel the vehicle. Due to the failure, the contact could not gauge when the fuel tank was full; therefore, fuel would splash out of the tank once it reached capacity. The contact stated that fuel would splash onto her clothing or onto her face because of the failure. The contact called a dealer and the service mechanic confirmed that the failure was common and that her fuel tank would need to be replaced. The manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 142,000.
The check-valve nipple on the gas tank of my 2011 Jeep Wrangler is broken. You can see it and smell the gas vapors leaking from this nipple. The vehicle has 86K miles. The Jeep failed our Delaware state inspection because the check engine light came on. The Jeep smells like gas and in addition to harmful vapors, it is a serious safety issue and an explosion danger. Two service stations attempted to fix this without success. The error code is P0455 for an emissions leak. The most recent service station ordered several previously-owned Jeep gas tanks but they all had this same failure. They next ordered a new gas tank from Jeep which was out of stock for several months, indicating they can not keep up with the demand for these failing nipples. When the new gas tank finally came in, this same nipple was broken and this was a brand new gas tank. …
(1) Since October, I have had airbag failure in my Wrangler Rubicon. The failure is the 2nd time for the same defective parts. Jeep has failed to repair/replace the parts. I've been waiting for two months. I cannot drive with no airbags. It's a death sentence and SUICIDE to drive without airbags. There is a recall on this same defect issue, yet Jeep has continued to ignore this issue. (2) Jeep repaired a recall on my sidemirror defrosters a few years ago. After their repair, the defroster never worked again. (3) My heated seats failed to work, due to known defects. I've been without the deated seats for more than 2 years now! Jeep refuses to fix their defects.
Jeep wranglers have a common problem with the fuel inlet. It clogs over time then will cause fuel to spill over or click off constantly while fueling the vehicle. This gets worse in cold months. I have spilled fuel hundreds of times over the years while fueling. Jeep forums and YouTube talk about the widespread issue. No warranty or recall? Perhaps after a gas station goes up in flames
Driving down road vehicle started to flame from right front passenger side near front. Pulled over. Got out in time at which time vehicle went up in flames. Called 911 and fire department came put out fire left fire reignited and they came back to put out. Called insurance, filed case with Chrysler got no response. Vehicle was not modified or used for off road this was a vehicle used for regular commute to work. The vehicle was traveling a speed of approx 35 MPH on a city street. Raymond street. Believe it was an issue with fuel system in relation to engine.

I was driving at under 10 MPH, on a texas state road when the plastic fuel line which is connected to the underside of the body with some type of adhesive failed. This dropped the fuel line directly on the catalytic converter, which melted the fuel line causing a fire that spread to the engine compartment. Apparently this is an issue on the 4 door model wranglers as the 2 door wranglers have a plate preventing this. This issue should be looked at on all 4 door models, ranging from 2008 through at least 2013. I have looked at other 4 door jeeps and see that they have the same potential issue there is nothing that prevents the fuel line from coming into contact with the exhaust and potentially causing a fire.
Using my 2011 Jeep Wrangler (right hand drive), I deliver mail for the U.S. Postal service. Was delivering mail on my rural route. Date was 4th of feb.2014. The problem was a fire in the engine compartment. Causing damage to the wiring harness , many other wires, compartment plastics ,and gas line. The cause appears to be hot oil from the transmission dipping onto the engine and transmission . I only see that the fill tube on the transmission was the leak. I heard a fire ignite , open the car hood and seen the black smoke I then put out the fire. It is now the date-March 18 ,2014. I have no support from Chrysler corporation for repair of my problem. Their investigation stated an investigation into the incident found no manufacturing defect that caused the incident on 2-3-2014. I have now turned this over to my car insurance company . They say I should use the lemon law. …
Really annoying and very dangerous!! Each time we fill up our 2011 Jeep Wrangler with fuel, just as the pumps automatic shut-off clicks, fuel will blow out and all over whoever is holding the pump handle. There is no indication that this is going to happen, except for the click from the pump handle a split second before you get doused. We checked with our Jeep dealer to see if there is a recall, and they said there was not, however it appears to be a problem with the "inlet check valve"; a mechanical item that appears to be defective, and a severe safety concern, but is somehow not under warrantee. We went on-line to research and found similar issues with other Chrysler vehicles, including 2007-2009 Jeep wranglers. …
My 2011 Jeep Wrangler has major electrical problems. The windshield wipers wouldn't turn off even after shutting off the engine. I pulled the fuse but they still stayed on. I could smell something electrical burning so I had to disconnect the battery. Also the door locks don't work and front cigarette lighter stopped working. I called the dealer and made an appointment to bring it in. While driving to the dealer the Jeep started to shake horribly when accelerating (due to electrical issues with the fuel pump). The dealer says that I need a new totally integrated power control module (TIPM). The cost is well over $1000 (the vehicle is out of warranty). When I searched TIPM problems on-line I found that Chrysler has tons of complaints about this but the only issued a recall on a few vehicle models and Wrangler wasn't included. …
In July 2017, vehicle did not pass emission requirements at state inspection. Upon investigation, determination was made that a plastic hose connection on top of tank had broken and that entire tank needed to be replaced. Replacement availability was not a problem - over 100 in stock locally (really? This must be a recurring problem!) replacement cost, parts & labor - $1200.) first replacement had same problem and was replaced immediately at no cost. Second replacement has now developed same issue & and now, after approximately 6+ months must be replaced again. It should be noted that there hasn't been any accident, or trauma of any kind to vehicle. Although replacement cost is not to be ignored, it is my contention that this obvious design flaw creates a significant safety hazard. In the event of a rollover, gasoline would free-flow from the tank onto the muffler.
