Accelerator Stuck problems of the 2014 Jeep Wrangler

While driving on highway in passing gear the gas pedal gets stuck and accelerates continually while having to keep left foot on brake pumping gas with right foot to disengage the gas pedal. This has now happened 6 times in a month. Extremely scary and dangerous!.

On 6/23/16, I was driving my 2014 Jeep Wrangler unlimited sahara on a highway at approximately 65 mph. I accelerated to merge into the left lane and then, after letting up on the gas pedal, the vehicle continued to accelerate at the same rate of speed. I pressed the brake pedal and the vehicle slowed as expected but I heard a distinct "popping" noise, seemingly as if the gas pedal had popped back into place. Just a few miles later, while driving in the left lane, I accelerated a bit to keep up with traffic. The accelerator "stuck" a second time, and so I pressed the brake pedal again and the vehicle responded again by slowing but this time, when I went to accelerate again to keep pace with traffic, the gas pedal was completely non-responsive (I. E. , the pedal had seemed to fall to the floor and pressing it did not result in any further acceleration). I pulled onto the left shoulder of the highway and called roadside assistance to have it towed to the Jeep dealership. Dealership verbally told me computer fault code read as "accelerator pedal in correlation" and said the gas pedal module was reading incorrectly. Service advisor admitted to having seen this problem before. When picking up vehicle, service advisor told me that problem was due to excessive dirt on/behind the gas pedal. There is no way it was caused by this, as Jeep has not been taken off-road, no one drives it with muddy shoes, etc. Accelerator pedal assembly was replaced and pcm was updated to the most current software level. Previously on this vehicle, the sentry key was replaced as was the entire instrument cluster, as was the front stabilizer/sway bar. Not sure if the stuck accelerator is due to a computer/software glitch or a mechanical failure. A quick google search revealed that issues with "stuck" accelerators on this make/model/year vehicle are not uncommon. Invoice attached. Please investigate.
