What 2000 Lexus GS400 owners say
Speed control & acceleration
I was traveling with my father, ming suen on I-95 south bound near I-15 inter-change in my 2000 Lexus GS400(30900 miles). The accelerator got stucked(not by carpet or floor mat) mechnically, and my car downshifted itself and went into full power acceleration at the engine speed of over 5000 RPM. I tried to brake with full force, but failed to stop the vehicle, and the car was going at 85mph and gaining speed! The whole incident last for about 3-5 minutes, and I dialed "911" and tried to ask for help. Before the call was connected, I magically regain control of my Lexus. The accelerator dis-engaged and the engine speed returned to normal. I felt the brake was losing power and became very weak. I got out at the nearest exit and pulled into a gas station. As I got out my car, I could smell the brakes were burning, and the front right brake was fried. …
While driving on the highway my car suddenly stop with no apparent reason at all. I tried to accelerate but it did not responded, eventhough the engine was running perfectly. Everything was working but the accelerator. When taken to the Lexus dealer they told me the problem was with the electronic control module. They told me it will cost me around $3,000.00 to replace it. Is this normal for this car to happen or is it normal wear and tear?. We did not have an accident because it was early in the morning but it could be worse during heavy traffic hours.
