“Lexus stuck pedal--I drive a 1998 Lexus GS400 which I bought new. When I first bought it, I'd pressed the pedal all the way down( floored it ) many times and everything was fine. However in more recent years, I rarely floored it . One time last summer, I pushed the pedal all the way down to pass a car and the pedal stuck. My car accelerated from 35mph to 70mph in a matter of seconds on a local road. I hit the brakes several times but it kept speeding up. I was able to pry up the pedal up with my toe averting a near-accident. …”
NHTSA complaint #10332417, filed 2010-05, 180,000 miles“On the first day I purchased my Lexus in virginia I almost drove the car over the curb. I thought my foot hit the gas accidentally, but it had not. Since that time I have had numerous instances where the car lurched forward while I was stopped with my foot on the brake. Luckily the problem never caused an accident so I never complained about it. I thought my car was the only one with the problem. I read a recent article in usatoday about the problem, and realized that my car was not the only one doing it. …”

Second incident caused minor damage to the pump and moderate damage to my vehicle. I am reporting this at this time, because I have seen no reports of this problem on toyota vehicles as far back as 1998. …”
