Defect investigations
Unintended engine speed increase/sa
On may 13, 2003 the federal safety agency received an april 25, 2003 letter from mr. Peter boddaert petitioning the agency to conduct a petition analysis of certain 1997 through 2000 model year lexus 300 and 400 series vehicles for problems of vehicle speed control linkages which results in sudden, unexpected excessive (vehicle) acceleration even though there is no pressure [sic]applied to the accelerator pedal.in support of his petition, mr. Boddaert cites a number of odi reports concerning vehicle speed control linkages in the subject vehicles.included amongst the thirty-six reports he cites is one involving a lexus that collided with five other cars in the space of one-half mile before it could be stopped.odi found no data indicating the existence of a defect trend related to the petitioner's allegations at this time.therefore, there is no reasonable possibility that an order concerning the notification and remedy of a safety-related defect would be issued as a result of granting mr. Boddaert's petition.consequently, in view of the need to allocate and prioritize the federal safety agency's limited resources to best accomplish the agency's safety mission, the petition is denied.

Dt: the caller said while driving 50 MPH the vehicle accelerated to a faster speed very quickly. There was an accident. The caller sustained injuries. A police report was taken. The caller said the vehicle was accelerating without warning for about a year. The caller called the manufacturer the day of the accident and told them about the problem. Dealer said they would get back to him. He was told nothing was wrong with the car a few weeks before the accident. Dealer was contacted after the accident, and they said they will set up an appointment to find the cause of the problem. On september 26, 2005 at 8:00 am, manufacturer said they would call in two days. This was before the accident. After the accident they said they would come and look at the vehicle. The caller said she called manufacturer again on september 27, 2005 at 9:00 am to tell them of the accident, they said someone would call back. On september 28, 2005 manufacturer said it would take six to eight weeks to look at the vehicle. The caller told them they were going to sue, and the manufacturer said they will not come to look at the vehicle.
After starting the vehicle, it suddenly accelerated at a high speed. The condition caused the vehicle to hit three parked vehicles and one vehicle in motion. The consumer received minor injuries to her face due to air bag deployment. The other driver and passenger of the other vehicles appeared to show no injury.
Three events occurred where my 2000 lexus 400 accelerated on its own in beginning to start moving by releasing my foot from the brake. The first incident occured in cannon falls mn. We had come to a stop at a stop light and when the traffic started moving I lifted my toe from the brake and the car leaped forward --- I immediately slammed on the brake again since my toe was still on the brake. It lurched several times and then quite. I barely stopped it before hitting the car in front of me. It happened again the same way several weeks later but not as violent. The third time happened as I was bringing my car into lexus to diagnosis the problem. This time it violently leapt forward causing me to brace myself on the steering wheel to get more leverage on the brake. It lurched forward what seemed to be in jumps of six inches to a foot with me pushing as hard as I could on the brake. Finally I had the presence of mind to shift into neutral. Again I barely was able to stop it before hitting the car in front of me. This is a highly dangerous condition and I have told lexus I will not drive the car again until it is fixed. Lexus is looking at it and so far claims that nothing is wrong. Ie nothing can be found with the diagnostics. I am willing to let the federal safety agency have the car for testing if I can get replacement transportation during the testing. Norm talsoe.
