Ok here is my $.02.
I purchased my used 05 about a year ago from a stealer. It came with the A\W floor mats and the carpet ones. The carpet ones went directly onto a shelf in my garage and the A\W ones were put in by them self’s. I noticed at the time that there was nothing to hold the mats in place. I did see there were two holes located right by the drivers’ seat were something would be used to attach them but the mat and the floorboard holes did not line up, so thought they were aftermarket and the hardware would not work.
About two mounts after I got it, I accelerated hard to get in front of another vehicle before the next red light. While approaching the light I found myself almost unable to stop the vehicle. I got the vehicle stopped just passed the crosswalk (very hard braking while engine revved out of control). Fortunately there wasn’t any traffic coming the other way so all was ok. While trying to figure out what happened, I discovered that the floor mat had slid forward up onto the firewall so when the gas was pressed it became stuck on the mat. I don’t consider my self an idiot, in fact the opposite. The problem as I see it is the mat has to be secured properly. If you move your stock mat up onto the fire wall you will see that the pedal is able to touch it (stick). The cutting and ECU modes that are being done must be to compensate if the mat is not secured properly.
I received my recall letter a couple of months ago but wanted to find out more information (wait for others). I have been following this thread and am very reluctant to have this “safety update” done to my 4R. The “fix” that Toyota has come out with is BS in my opinion and sub par to the mats that are in my 4R. I will not give up my A\W mats for the POS Toyota is offering (even though my mat has significant wear from driving). I drove my 4R for a year knowing there was a problem with the mats and that I needed to make sure they did not slide forward, ok maybe I am an idiot for doing this, but I have done just fine with it. So that's my contribution to this thread.
I do think I will be looking into the mounting clips. Does any one have a part # on these? Any one have a pictures of there mats installed correctly (do your holes line up?)?
