Adaptive Equipment problems of the 2007 Toyota Highlander

I have a 2007 Toyota Highlander that had mat entrapment--I had after market mats as none were given to me when I bought the vehicle--I reported this to Toyota corporation and had vehicle inspected at dealership and rep said there was no defect in my accelerator--the vehicle had accelerated and I hit a picnic table and 2 bird feeder and a fence in my yard before I got the vehicle to stop. I would like to know what is different about my accelerator as the 2007 is not on recall but I feel it should be--they did not explain that to me just told me that my floor mat caused this to happen--I realize that but I would like an answer to my question--I blew a michelin tire and have damage to my bumper--total cost--about $600 according to Toyota garage--no answer from them except to say this was my fault.
