While car newly made remote key crank car that had been sitting without being driven 30 +days, I crank car and alarm sounded and flashing lights came on and would not turn off when car key taken out of ignition. Then the car began to crank all by itself without the key even in the ignition!!! I unhinged the battery cables and the car wrnt dead. Also smoke was coming from back engine area!! I towed car to Lexus dealer and they replaced the starter. The gear shift locked and the car drove for about a month whe check engine light came on reporting electrical/oxygen sensor code. The car started making a clicking chirping low sound coming from behind dash board. I reported it to Lexus dealer service a again but nothing done about it. An outside mechanic said it could be an electrical problem or faulty alternator.

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.
