The contact owns a 1999 Lexus GS400. The contact stated while driving at 1 mph, the vehicle accelerated independently. The brakes failed to engage while depressed on the brake pedal almost causing a collision. The contact informed the independent mechanic of the failure, but the vehicle was not diagnosed nor repaired. The manufacturer was not made aware of the failure. The failure mileage was 67,000.

Filed Sep 3, 2014 · Airbags, Body · 80,000 miles · CA · crash

In the process of making a u-turn on a private narrow street the automobile RPM jumped from an almost idle condition to over 3000 RPM. Every effort to brake the car and shift to neutral proved ineffective within the distance of approximately 30 feet. The automobile jumped the curb and struck a low garden wall forcing an engine stop. The airbags failed to deploy. My estimate of the speed when striking the wall was 30 to 35 MPH. I have pictures which show the brake streaks as well as total damage scene. In addition a next door neighbor heard the entire sequence of events and can verify the extent of the braking effort. To date lexus has stated that it was not an automobile defect. I am looking into appropriate legal action. The 1999 gs300 is identified as a candidate for uncontrolled accelerations in the recently complete toyota uncontrolled acceleration class action suite but my event is closed out due to the date of occurrence.
