2004 Toyota Prius accelerates due to gas pedal getting stuck in the floor mat. This morning I was driving my Toyota Prius 2004 that I bought from the original owner who mentioned all recall issues were addressed by Toyota dealership. He mentioned the dealer shaved off the gas pedal to make it shorter. But today, while on I 495 going eastwards just before entering the hov lane, I pressed the gas pedal all the way down to over take another slow vehicle. The car engine kept raising noise, and car started to accelerate on its own. I braked, the car slowed a bit but engine kept running fast. . . I realized this is potentially same issue that people reported on press and with lot of struggle trying to brake and slow down, realized and put the car into n, neutral position. I am lucky to know this from media reports, otherwise I would have been another dead guy on a Prius! while I was still on highway, needing to maintain speed I put the car back on drive mode, d and the problem continued. I realized, I can lift the gas pedal with my left foot, and succeeded in untangling the pedal from the floor mat. After I did that it was fine. I arrived at work, but with extreme shock and disappointment. I am wondering how this problem can still remain after a recall repair is done on this vehicle. This is completely unacceptable and my life was in total risk and I survived today purely because of my technical skills and knowledge about this car issue. I am an engineer in profession, a mechanical engineer with a masters degree and I understood how to react. If it was for my other family members in this situation the outcome would have been totally different. I am very very disappointed with Toyota corporation and also with you, the NHTSA for not making sure that all Prius out there are safety compliant. This is really terrible ! . . . Because its a known issue, and old issue that should have been corrected. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).
