One problem related to accelerator pedal has been reported for the 2007 Jeep Wrangler. The most recently reported issues are listed below.
The 2007 Jeep Wrangler unlimited x, otherwise known as the jk, lost engine power twice while driving 55 mph, and the electrical and engine shut off for 3-5 seconds and came back on. The electronic throttle for the gas pedal went into the default mode, where it won't go over 45 mph ,and the traction control shut off at this time also. This happened while driving at 55-60 mph. Also, the compass shut off also at a different time. Each time I had to pull off the road and restart the Jeep , and every thing worked again.
