I have a 2004 Toyota 4runner and a few months ago the accelerator pedal got stuck under the rubber floor mat. I purchased the rubber floor mat from a Toyota dealer and it was made specifically for the 4 runner. When the pedal got stuck, the engine was running wide open. I managed to get the vehicle in neutral and stopped before hitting anything. It was very frightening. It appears like the mat slid forward and that was what caused the pedal to get stuck. I had recently cleaned the mat and may not have had it positioned properly when I reinstalled it. I think the design of the mat is not safe due to the thickness of the mat at the front near the pedal. Future incidents are likely if the mat is loose and slides forward. I did have a carpeted mat under the rubber mat. The carpeted mat came with the 4runner when I bought the vehicle. This likely contributed to the rubber mat coming loose and sliding forward. If not installed properly, it appears like the carpeted mat could also slide forward and may cause the accelerator to get stuck.
