   OK - More information is out.   
   It APPEARS the problem is with the one part that is common to both the   
   drive-by-wire and linkage vehicles - the design of the actual pedal   
   assembly. Apparently the pedal, under some conditions can bind - but I   
   can't for the life of me figure out how it could bind that you could   
   not pull it back by getting a toe under it.   
      
   Anyway, the supplier of the pedal is going crazy trying to get a   
   redisigned pedal into production at all of their plants across North   
   America. I don't know if it is a materials problem, or what, but if   
   the bushing (or the entire pedal) is made from, say, nylon, and the   
   clearances are small enough, absorbing moisture (which nylon is real   
   good at,) could cause the bushing to swell and bind on the pin.   
      
   The design of a floor mat could contribute to this if it holds   
   moisture in close proximity to the pedal pivot.   
      
   At any rate, millions more floormats have just been added to the   
   recall.   
      
   Hopefully within a few days more information will be released, and the   
   problem will be 100% solved.

   Whether they have actually gotten pedals to stick "on command" or   
   whether the experience in europe has pointed them to the pedal design,   
   I have not heard. They must have thought the design was different   
   enough that the european experience did not apply directly to the   
   American vehicles or they would have addressed it much sooner.
