One problem related to tank mounting has been reported for the 2007 Jeep Liberty. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2007 Jeep Liberty based on all problems reported for the 2007 Liberty.
Beginning at approximately 35,000 miles on the vehicle, fuel would spit-back immediately after the fuel nozzle shut off. The amount of fuel spit back was significant, drenching the lower half of the person fueling the vehicle. At first, we thought this might be an issue with the fueling pump, but found it repeated itself at every pump and at every station we utilized. It does not seem to depend on rate of fueling, as even attempting to fuel slowly results in a dangerous spit back of fuel and potential drenching of the individual. The vehicle was inspected by the dealer and a defective valve in the fuel tank was diagnosed as the cause of the problem. Interestingly, after reporting the labor charge of $200 to investigate the issue, we were told that they have seen a number of Jeeps with this problem. One would think common problems could be found without this level of labor. The valve in question cannot be obtained as an individual unit and the entire fuel tank must be replaced at the cost of approximately $900. Given that numerous other Chrysler vehicles of this year, including wrangler, Dodge durango, Liberty, and other models across the Chrysler, Dodge, and Jeep brand exhibit this problem and that lacking significant moving parts, one cannot justify a fuel tank component failure after 35,000 miles, this issue is unquestionable a design failure. Given the immediate hazard of fire, long term health risks, and environmental impact of repeated events of fuel spit back from these vehicles requires intervention.
