Purchased vehicle used in 2013 11/17/2015 1. Engine continues to run when key is removed from ignition switch. While parked. First noticed last week 11/08/2015 (only as long as the preset time on the radio shut off or the door is opened) 2. With cruise control set and going up hill, transmission down shifts to maintain speed. While trying to keep speed up and then break applied, excessive force is required to dis-engage cruise control. While driving at normal speeds. For as long as I can remember. (break switch has been changed twice) 3. While filling fuel tank at gas station, paying close attention to the pump, fuel will pour out from the filler neck after the pump has shut off. For as long as I can remember. (many occasions) 4. Check engine light continuously on. Possible damage to hoses on emissions canister in left rear wheel well due to gas spillage? (as long as I can remember) 5. …
Amongst other issues: vehicle fails to start occasionally, from both cold and warm states. From completely off, turning the key begins ignition but often does not start the vehicle. Engine sputters but does not complete the start. On some occasions, depressing the gas pedal while trying to start the vehicle works, leading me to believe this is one of the widely reported TIPM issues plaguing jeeps from 2007-2014. I conclude the fuel pump fails to receive a signal to start from the TIPM which causes the ignition failure. In addition, I have had multiple electrical issues including doors locking and unlocking when the opposite corresponding buttons are pressed, windshield wipers turning on when the turn signal is used, warning lights on the dashboard reporting non-issues, failure of power steering, and failure to accelerate when the gas pedal is depressed. …

I have 2 problems number1 is the gas mileage it gets the mileage it says on the internet but I feel that is bad fuel mileage I had a 2000 Jeep grand cherokee with a v8 and got 25 miles per gallon on the high way you would think that a v6 would just as good or better but it is not .second problem is fuel spillage evrytime you fill up I have tried different things to try and stop the spillage but to no avail. I feel there should be a recall on this problem but there is no recalls for a 2008 Jeep they had recalls on some older jeeps but not mine it would be nice to see something done about this problem. Thanks [redacted]
Tl* the contact owns a 2008 Jeep Liberty. While the contact was filling the fuel tank, the fuel pump sensor did not alert her that the tank was full. As a result, fuel spewed out of the tank. The failure recurred numerous times at different fuel stations. The contact stated that she could not fill the fuel tank because fuel would flow out. The vehicle was taken to an independent mechanic who stated that the fuel station pump sensors failed. The vehicle was not diagnosed or repaired. The vehicle was not taken to a dealer. The manufacturer was notified of the failure and did not assist. The approximate failure mileage was 80,000.
When filling this vehicle with gas, gas with spew out all over the car and the person holding the nozzle that is still in the gas tank. No matter what gas station used/pump and no matter how slow or fast it is going. I do not " top off". The spillage can be between a cup to a half gallon for no reason in particular. This is a very dangerous issue and needs to be resolved.I have to guess each time how much to put in so I can limit the amount of fuel spillage. This has been happening for years with no resolution.

The failure mileage was 84,656. ...updated 06/30/16
When filling fuel tank to full capacity and fuel flow is shut off, fuel comes back up out of fill port spilling at least 2 cups of gas over filler and ground. Happens every time tank is filled full. This occurs while vehicle is stationary engine off while at any gas station. It is an apparent failure on a valve in the gas tank requiring entire tank to be replaced at the owners expense. Is a known issue to manufacturer.
