I have noticed a couple of times that when I put the pedal to the metal, sometimes it will stay floored when I let up. The pedal is still on the floor and I have to hit the brakes hard to slow the car down and then the pedal pops back up. It may be a geometry problem with the linkage (I know it's fly by wire) but it still may be with the pedal itself. It's not getting caught on the rubber mat. I figure an easy fix would be to put a small (1/4") piece of wood on the bottom of the pedal. It shouldn't affect the full throttle operation, but possibly aleiviate the sticking pedal syndrome. Anyone else experience this? By the way, it's a '09' RT automatic.

 

I havent had that problem but thats not good others have had similar problems sticking wide open
