In days of old many people would simply go out and disconnect the battery then turn on the headlights for about 20 minutes to fully drain all electrical power from the CPU (onboard computer). The reattach the cables and see if the glitch didn't correct itself and relearn your driving habits.
Downside is that it maynot correct itself and may erase any trouble codes from the computer memory. Another thought is you could run past your local auto parts store and see it they won't bring their scanner out and look for any trouble codes already stored on the memory.
Bottom line is, that while it is a PITA to take the Jeep in, the warranty will take care of the issue....unless it turns out to be bad gas.
