2000 LEXUS GS300 Vehicle Speed Control Problems

REGARDING MY 2000 GS 300 LEXUS. BRAKE, ABS, VSC, VSC OFF LIGHTS ALONG WITH LOUD ALARM DISPLAYED. ALSO HAS HAD AN ANNOYING ON AND OFF CHIRPING NOISE BEFORE THIS ALARM SOUNDED. THE BREAKS APPEAR TO BE WORKING WITHOUT ANY PROBLEMS. THE CHIRPING NOISE IS HEARD ON THE DRIVERS SIDE AND DOESN'T SEEM TO MATTER WHETHER CAR IS MOVING OR DRIVING AND SOMETIMES IS NOT HEARD AT ALL AND THE CAR DRIVES FINE WITHOUT ANY MECHANICAL PROBLEMS. BUT WHEN THE BRAKE LIGHT CAME ON IT WAS ACCOMPANIED WITH A SHRILL ALARM THAT SOUNDED FOR ABOUT 10 MINUTES AND WENT OFF. I TOOK THE VEHICLE TO MY MECHANIC AND HE SAID IT WAS THE HYDRAULIC BRAKE PUMP AND WOULD COST $3700 TO FIX. THIS IS A LOT OF MONEY AND I AM AFRAID THE BRAKES WILL GO OUT AND AFRAID TO DRIVE IT SINCE MY BRAKES MAY SUDDENLY GO OUT. *TR

BOUGHT A 2000 CERTIFIED PRE-OWNED IN 2005 FROM LEXUS DEALER. IN 2007 ON A RESIDENTIAL STREET, A DRIVER WAS DRIVING VERY SLOW AND STARTED TO PULL OVER. I QUICKLY WENT AROUND HER TO PASS, AT ABOUT 35 MPH, BUT AFTER RELEASING THE GAS PEDAL, CAR SPED UP INSTEAD. TRIED TO SLOW DOWN WITH THE BRAKES, BUT IT SPED UP MORE. THEN SLAMMED THE BRAKE PEDAL WITH BOTH FEET AND PUT IT ON PARK TO AVOID HITTING STOPPED CARS AHEAD. IT STOPPED IN "PARK" BUT WAS STILL REVVING HIGH. I GOT OUT OF THE VEHICLE AND IT WAS STILL REVVING OVER 6 RPM! I BENT UNDER THE DASH AND TRIED TO LOOSEN THE GAS PEDAL WITH MY HAND THINKING IT WAS STUCK BUT IT WOULDN'T STOP REVVING SO I TURNED THE ENGINE OFF. BEFORE TURNING ENGINE ON AGAIN, I MADE SURE NO CARS WERE AHEAD OF ME AND PREPARED TO PUT...

I WAS TURNING ONTO THE FREEWAY (UPHILL ONRAMP) I STEPPED ON THE GAS GOING ABOUT 20 MILES AN HR WHEN SUDDENLY MY CAR WOULDN'T STOP. ACCELERATED SO QUICKLY. AT FIRST I THOUGHT MY FOOT WAS TOUCHING THE GAS ACCIDENTLY SO I MOVED AND APPLIED THE BRAKE WHICH WAS NO HELP, AFTER I TOOK MY FOOT OFF THE BRAKE IT ACCELERATED FASTER I WAS TERRIFIED. I SLAMMED ON THE BRAKES WITH BOTH MY FEET AND THE CAR SLOWED ENOUGH THAT I WAS ABLE TO TURN IT OFF. EVEN WHILE I APPLIED THE BRAKES THE CAR WAS STILL TRYING TO PULL FORWARD AS I TURNED IT OFF THE STEERING WHEEL LOCKED. THIS WAS THE WORST EXPERIENCE I HAVE EVER HAD AFRAID TO DRIVE IT I HAD IT TOWED TO THE NEAREST GAS STATION TO HAVE IT CHECKED. I'M HOPING THAT THEY WILL FIND THE PROBLEM BECAUSE I DON'T WANT THIS TO EVER...

WHILE DRIVING MY LEXUS GS 300, THE VEHICLE STOPPED ACCELERATING! THE VEHICLE WAS DRIVING NORMALLY AND ALL OF SUDDEN IT STALLED OUT (ENGINE STILL RUNNING) BUT NO ACCELERATION AT ALL, ALMOST CAUSING ME TO GET HIT BY ANOTHER VEHICLE. THE VEHICLES VSC AND THE ENGINE LIGHT CAME ON AFTER THIS HAPPENED.. I PUSHED THE GAS PEDAL ALL THE WAY TO THE FLOOR BOARD AND NOTHING HAPPENED, AFTER A MINUTE OR SO, IT BEGIN TO ACCELERATE BUT ONLY ABOUT 20-30 MPH. AFTER CONSTANTLY HOLDING THE PEDAL TO THE FLOORBOARD, THE CAR BEGIN TO ACCELERATE NORMALLY AGAIN FOR A FEW MILES. IT DOES THIS CONTINUOUSLY WHILE DRIVING NOW. AT TIMES I HAVE HAD TO PULL OFF THE ROAD AND LET THE VEHICLE SIT FOR AWHILE AND THEN IT WILL RETURN TO FUNCTIONING NORMALLY. THE CODES THAT THE MECHANIC PULLED UP FROM THE ENGINE AND VSC LIGHTS WERE FOR THE THROTTLE BODY SENSOR...

TL* THE CONTACT OWNS A 2000 LEXUS GS300. WHILE DRIVING AT 5 MPH, THE CONTACT STATED THAT THE VEHICLE ACCELERATED WITHOUT WARNING. IN ORDER TO STOP THE ACCELERATION THE CONTACT HAD TO SHIFT THE VEHICLE INTO PARK. THE VEHICLE WAS TAKEN TO AN AUTHORIZED DEALERSHIP WHERE THE CONTACT WAS INFORMED THAT THE FAILURE COULD NOT BE REPRODUCED. THE CURRENT AND FAILURE MILEAGES WERE APPROXIMATELY 98,000. UPDATED 8/2/10 *CN UPDATED 08/09/10*JB

TWICE IN THE SAME DAY OUR 2000 LEXUS GS300 EXPERIENCED ACCELERATION PROBLEMS SIMILAR TO THOSE NOW INVOLVED IN THE INTERNATIONAL INVESTIGATION OF TOYOTA PRODUCTS. THE ACCELERATION BEGAN AS THE VEHICLE WAS STOPPED. I HAD TO PUSH THE BRAKE WITH GREAT FORCE TO KEEP THE VEHICLE FROM MOVING FORWARD. WHEN I PLACED THE CAR IN NEUTRAL, THE REVVING OF THE ENGINE STOPPED. THE FLOOR MAT ON THE DRIVER'S SIDE HAD NOT BEEN MOVED AND WAS NOT INTERFERING WITH THE GAS PEDAL. WE CALLED A MECHANIC WE USE FOR THE CAR AFTER THE INCIDENT TO FIND OUT WHETHER ANYTHING SIMILAR HAD BEEN REPORTED OR IF LEXUS HAD ISSUED A RECALL. WHEN WE LEARNED THAT OUR MODEL VEHICLE WAS NOT INDICATED AS HAVING A PROBLEM, WE DID NOT DO ANYTHING FURTHER ABOUT THE PROBLEM. WE'VE NOT HAD THE PROBLEM SINCE THEN. HOWEVER, I THOUGHT IT BEST TO REPORT THE PROBLEM AFTER HEARING ABOUT...
