“When I try to depress the accelerator of my 2003 Toyota Avalon, there are times when I feel resistance. If I press to overcome the resistance, it then races and does not return to normal position. It has happened multiple times over the past 4 years w/o any pattern. Nothing was done to correct it.”

NHTSA complaint #10317394, filed 2010-03, 38,122 miles

“I drove into a parking spot, put my car into park & released my foot from the brake. The car rolled back as if it was in reverse. I applied the brakes, shifted the gear into drive & drove back up into the space. I put the car back into park, released the brakes, only to have the car roll back again. I pulled back up into the parking spot, shifted back into park & this time put on parking brakes. I got out of the car & went into the store. When I came back, my car would not start. Not only would it not start, it would not make any sort of noise (which is how I knew it wasn't the battery). …”

“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.”
