Over the past 9-12 months i have owned the 4runner, i have noticed the floormats slide up behind the brake and acceleration pedal when i am constantly switching between the two (eg. heavy traffic, long trips, etc.). i usually am able to pull them back down at a stoplight or stop sign; however, on tuesday, july 29th, i was involved in an auto accident that was not only in heavy traffic, but while on a 200+ mile trip as well. i believe that the floor mat caused my car to have limited braking ability in addition to possible increased acceleration. the nhtsa's findings seem to be consistent with this. additionally, the complaint with nhtsa id number: 10384563 states that "i pushed on the brake... but the car continued accelerating" and then "toyota inspected the vehicle... and said they adjusted the mat" is one of many that have findings consistent with the malfunction that caused my wreck. *tr
