One problem related to accelerator stuck has been reported for the 2012 Jeep Wrangler. The most recently reported issues are listed below.
On 3 occasions my Jeep Wrangler's accelerator pedal has stuck to the floor. Shifting to neutral would not bring the pedal up. Manually pulling the pedal would not make a change. Twice I had to turn off the car in mid traffic. The third time I was able to coast to the side of the road.
