What owners report
Fuel was spilling out underneath vehicle every time I filled up. The issue was that the plastic housing where the fuel filler tube connects to the gas tank hardened and deteriorated to a point where it begins to leak. That plastic appears not to be ethanol resistant. Indications a leak will or is occurring: P0456 code or fuel dripping down under vehicle or smell of fuel.
Gasoline is leaking out when filling up. This is a know issue with previous year models. The problem is so serious that Jeep is have a problem manufacturing the part to fix it. There should be a recall.
I currently own two of the same year vehicles. They BOTH have the same problem with the ECM. I have also spoken with multiple people who own Jeep vehicles @ the same year. We all seem to have; lifter, Rod knocks, oxygen sensors and ECM that have caused multiple other problems (and severe accidents) due to their malfunctioning. I have had both of my vehicles to licensed mechanics, who have advised me of the same problem. One of the 2011 Jeep Libertys have been owned by me since brand new, the other was bought used. PLEASE PLEASE help us out!!! I have spent so much money trying to repair these vehicles!!! THE ECM & OXYGEN SENSOR need to be recalled!!!
The contact owns a 2011 Jeep Liberty. The contact stated while adding fuel to the vehicle, there was no indication that the fuel tank was full, and fuel splashed outside of the vehicle. The local dealer was not contacted. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure. The failure mileage was approximately 104,000.
2010 Jeep Liberty spontaneously caught on fire and exploded on Friday April 15, 2016. My stepdad and I were out and we stopped and picked up a pizza on the way home and everything was just fine the whole drive home, no smell, no driving issues, no smoke, no overheating dings, no funky sounds. We pulled into the driveway to park and turned off the car, my stepdad got out first, and when I opened my door I said 'ooh it smells like fall!' (I thought the neighbors were having a bonfire or something.) then I saw it and told him 'the car is smoking!' and I got out of the car and got away from it. He tried to open the hood thinking it was a radiator or something but it was so hot it burned his fingers and then he lifted it a bit with a screwdriver as we went to get the fire extinguisher and we saw the fire start shooting out of the sides. It was so hot and so fast. …
When filling the vehicle with gas, the fuel overflows onto the side of the car, onto the ground and sometimes, if you forget and don't stand back far enough, is will splash onto who ever is filling the tank. This started in the fall of 2013 and continued off and on until the winter of 2014 when it became an every fill up issue. We did some research and found that older models of Jeep Liberty had the same problem, and had been recalled to have the tanks replaced. When we contacted Jeep they told us that my vehicle was not included in the recall, and that they would not do anything to help with the cost of replacing the tank. I had some other work done this last week on my Liberty and found out that to correct the problem, I would have to pay $710.00 for the tank and $365.00 for the labor. …
Fuel Spit Back During Refueling. When refueling at any gas pump, flammable fuel almost always spits back out of the filler hose, down the side of the vehicle and pools on ground by the tire. There has been a recall issued for the same issue and same vehicle model: Jeep Liberty KK, which runs from 2008-12. However, the recall only covers year 2008.
On Friday, 07.07.2017, as I was driving into a turn lane from the hwy, I had slowed way down for traffic then picked up speed slightly, not even 10 MPH, to follow cars in the turn lane when the accelerator became sluggish and the Jeep came to a stop. As I pressed the accelerator again there was a very loud pop from under the hood. Everything quit, the engine, the electric, the starter would not turn over when I tried to start it again or the emergency flashers. Just before this happened the engine light and, what I found out later, the electronic throttle control light came on. I was confused at what just happened. Thinking what I saw next was steam coming from under the Jeep was steam I popped the hood to go look. There was traffic all around on the hwy. …
