2004 LEXUS LS 430 Vehicle Speed Control Problems

WHEN PULLING INTO PARKING SPACE AT A LOW SPEED (2 MPH) CAR SUDDENLY ACCELERATED EVEN THOUGH ACCELERATOR PEDAL WAS NOT BEING DEPRESSED. OPERATOR'S FOOT WAS ON BRAKE PEDAL THE ENTIRE TIME BUT CAR WOULD NOT STOP UNTIL IT HIT A PARKED VEHICLE. AT THE TIME THE CAR WAS BEING TURNED TO THE RIGHT COMING INTO THE PARKING SPACE. THERE WAS A HIGH CURB (~10 INCHES HIGH) AT THE FRONT OF THE PARKING SPACE AND A MEDIAN BUT THE CAR JUMPED OVER THIS AND STRUCK THE PARKED ON THE OTHER SIDE OF THE MEDIAN.

I HAVE A 2004 LEXUS LS 430 THAT HAS A RANDOM PROBLEM THAT THE DEALERS TELL ME IS NORMAL. ON OCCASION WHEN I ROLL TO A STOP THE CAR LUNGES FORWARD ON ITS OWN FORCING ME TO APPLY EXTREME PRESSURE ON THE BRAKE TO STOP THE VEHICLE. IT ACCELERATES JUST FOR A SPLIT 2ND THEN STOPS. I HAVE LEARNED TO STOP APPROX. 20' BEHIND A VEHICLE JUST IN CASE THE CAR DECIDES IT WANTS TO LUNGE FORWARD. THIS HAS HAPPENED NO LESS THAN 6 TIMES SINCE WE PURCHASED THE VEHICLE NEW IN 10/2003. I HAVE EXPLAINED THE PROBLEM TO THE DEALER AT LEAST 4 TIMES AND THEY TELL ME THEY CAN NOT FIND A PROBLEM AND ITS NORMAL. WITH THE LATEST TOYOTA PROBLEMS I SUSPECT THERE IS AN ELECTRICAL PROBLEM AND I WANTED TO REPORT THE PROBLEM TO YOU. *TR

THE CONSUMER'S 2004 LEXUS LS 430 HESITATED INTERMITTENTLY WHILE ACCELERATING TO ENTER A HIGHWAY. *NM THE VEHICLE WAS TAKEN TO THE DEALER TWICE AND ALL THEY SAID WAS THAT THE VEHICLE HAD TO LEARN THE CONSUMER'S DRIVING HABITS AND IT WOULD CORRECT ITSELF. THEY ALSO SAID THE WOULD BURN SOMETHING INTO THE COMPUTER BOARD. THE VEHICLE HESITATED AGAIN WHILE THE CONSUMER WAS MAKING A LEFT TURN FROM A VERY LOW SPEED. AFTER A FEW SECONDS THE VEHICLE FINALLY ACCELERATED BEFORE THE VEHICLE WAS HIT BY ONCOMING TRAFFIC. *NM
