Please also check out the statistics and reliability analysis of the 2007 Jeep Grand Cherokee based on all problems reported for the 2007 Grand Cherokee.
When attempting to start the (parked) car, when the key is turned everything turns on (radio, dashboard lights, seats ect) like it normally would start but the engine doesn't turn over or crank at all. . . When all the other lights go off the engine and oil light remain on. No clicking sound whatsoever, but I believe you can hear the fuel pump kick in. When the key is turned to the off position after it won't start, the accessories will occasionally stay on (such as the the seat when it has the easy entry option selected will stay in the driving position). Nothing seems to make it start. Jumping the battery does nothing. Putting it in neutral to start doesn't do anything. It's usually just a matter of time before it decides to start again. . . Sometimes hours, sometimes days. When taken to the dealership they can never diagnose the issue because they are unable to duplicate the issue. For whatever reason, possibly just a coincidence, replacing the battery in the key fob seems to delay the issue from happening again for a few months. Although this may not seem like a straight forward safety issue, the problem has left me stranded at a gas station in the middle of winter while being 8-1/2 months pregnant and most recently left me stranded with my 8 month old baby. I should also note that this problem never occurred until some time after the last recall was resolved.
