1 Automatic Transmission problem

Failure Date: 04/15/2009

The gas pedal on our 2003 Toyota Avalon began sticking when car was 5 years old. It was most noticeable when the car was stopped and we wanted to begin moving. It became hard to depress until a good bit of pressure, and then the car would lurch forward or backward very quickly. We tried lubricating the pedal mechanism but that didn't work. The dealer said they fixed it at our 100,000 mile check but it still stuck. The recent problem with Toyota gas pedals may have been around a lot longer than thought.
