Nothing engaged an then all of sudden it worked like it was back to running normal for like 10 seconds then lost almost all the power an you can push the padel to the floor almost befor it will even engage. It's my everyday driving car it not safe to be driving, when it's malfunctioning in the ecu, vsc , cruise control quit because of what happened. There a recall on the vsc for the lexus gs 300 for having malfunction problems. But it only let's the you use only the last 25 percent of the gas padel, it don't do anything in till almost to the floor. This happened in brookville pennsylvania, when I was turing left on to route 36 south. I also had to replace my thottle body because when this all happened, my thottle it was stuck in wide open thottle. It was very dangerous it could have easily put others citizens an my life in danger, witch could cause serious injuries, or in a worse case death. I'm filling out this foam in regards of a recall, to fix or replace the ecu, vsc , cruse control .

Referring to a 1998 lexus gs300, rear wheel drive car with 84,000 miles. On saturday, june 19, 2010, I was coming to a stop at an intersection with a 2 way stop sign, with my foot on the brake. My car after slowing down a bit, suddenly accelerated, almost resulting in an accident as I 'cruised' across the intersection instead of stopping. I called lexus and they advised that I bring the car in. I drove there about 15 miles, and on the way there I stopped about 100 feet behind another car which was stopped at a red light. I was at a total stop, my foot on the brake, and the car suddenly lunged forward. There was no accident because I was so far behind the car in front of me. I drove to lexus. They examined the car and told me they found nothing wrong, including with the computer. They then took me for a drive, perhaps 20 or 30 minutes, stopping and starting, and the problem could not be duplicated. I was too afraid to drive the car away as this sudden acceleration happened twice that morning, so I bought a new car on the spot. I was of the understanding that the problem of sudden acceleration did not involve the gs series. Lexus did allow my gs300 as a trade-in. Both times when the car accelerated, I had no distractions and am certain that this description is absolutely accurate. Also, I had only the original mats in the car and they were set properly with the hooks through them as they should be.

When at a stop sign or red light, with my foot on the brake pedal, the car accelerates. I press on the brake pedal and, usually, the acceleration slows down. This happened 3 times in 2 days and the third time the acceleration did not stop, the car really accelerated, I pressed on the brake pedal as hard as I could and the rear tires were smoking so I turned off the key. The dealer had the car for a week and could find no problem. Before I got the car back into my garage, it happened again but not too badly.
