Jeep gas pedal goes and sticks floor

I have a 07 Sahara unlimited twice in past month I was driving. The gas pedal goes all the way to the floor and sticks. I do not have floor mats in my Jeep. I try everything first time it popped back up when I turned Jeep off. The second time even after I was pulled over and Jeep was off it didn’t pop back up till I restarted the Jeep. I’m about to trade it in because all I hear is this is impossible.

I would say either your throttle cable or throttle body is sticking or if it's drive by wire it's the reostat assembly on the gas pedal

Try the easy possible fix of using some WD40 or Release-All and spraying the linkage under the hood.
