Service Brakes Problems of Lexus LS400

The evening of 3/7/15 my wife and I drove from cedar rapids, IA. To our home in muscatine, IA. As we exited I-80 after almost one hour of constant interstate driving, the car stalled at approximately 5 mph as we came to the stop sign at the end of the exit ramp. We lost power steering and power brakes as well, causing panic. This is not the first time this has happened in the two years we have owned this car. It seems to occur after prolonged interstate driving only. It did not occur that morning because we broke up the trip to cr with a stop in iowa city. This is a horribly dangerous condition and after researching on the internet last night, a very inherent problem with this model and year. Toyota's TSB eg003-96 speaks of it and its remedy, published 10/7/96. The remedy is to replace the faulty ecm with part 89661-50224; a very expensive fix and presumably the reason Toyota did not voluntarily recall the car. There was no forced recall either, but should have been due to the many complaints reportedly submitted to the NHTSA and potential deadly consequences of losing control of the vehicle due to faulty ecm programming. Please make this posting available to any potential 1995 Ls400 owners and/or force a recall of this vehicle.

As I was driving, my vehicle started accelerating on it's own. When I had previously checked the speed odometer it said 50. All of a sudden the vehicle started gaining speed. I took my foot off of the gas pedal and the speed kept accelerating. I pressed the brakes and the brakes did not work! the vehicle kept accelerating. I saw a side road and turned onto it. I kept trying to stop the vehicle and it kept going. I thought to pull the emergency brake and it slowed the vehicle considerable, but it kept moving. The engine continued to accelerate. I kept pumping the breaks with the emergency brake on and the car was still moving. It finally stop, but the engine was still accelerating. I put the vehicle in park and the more the engine accelerated. I put back in drive and it continued to accelerate. The vehicle started smoking. I didn't know what to do or what was going to happen to the vehicle. I told my sons to get out of the car. I turn the engine off, the car jumped and I ran away from the car. The vehicle was still smoking. I called 911. The car stopped smoking and remained in place. My husband came and started the vehicle it accelerated and he pressed the gas pedal and it stopped. I drove the car home and parked it. I am not driving the vehicle and this is the reason that I have not entered a VIN number.
