1. WHILE PULLING INTO A PARKING SPACE, AT 2-4 MPH, WITH MY FOOT ON THE BRAKE, THE CAR SUDDENLY ACCELERATED AT FULL SPEED, JUMPING THE CURB AND HITTING A TREE WITH FULL FORCE. BECAUSE OF PREVIOUS CONCERNS WITH THROTTLE PROBLEMS NOTED WITH THE DEALERSHIP AT 1000 AND 5000 MILE CHECK, I IMMEDIATELY CALLED THE LEXUS DEALERSHIP. AFTER A CONFERENCE CALL WITH LEXUS ROADSIDE ASSISTANCE AND THE DEALERSHIP, MY CAR WAS FLAT BEDDED TO THE DEALERSHIP. THE FRONTAL CRASH RENDERED THE VEHICLE UN-DRIVABLE. RADIATOR DAMAGE WITH LEAKAGE OF FLUID COVERED A PORTION OF THE PARKING LOT. THE LEXUS DEALERSHIP SAID THEY WAS NO PROBLEM WITH THE CAR. I COULD HAVE BEEN KILLED OR SOMEBODY ELSE LIVE COULD HAVE BEEN IN DANGER. 2. THE FRONT AIR BAGS DID NOT INFLATE. 3. THE BRAKE ROTORS HAD TO BE CORRECTED AT 1500 MILES AND A "PART" WAS ORDERED AND PUT ON THE CARE TO CORRECT THIS PROBLEM. 4. THE CAR WHEN DRIVING AT ABOVE 50 PULLS TO THE LEFT AND FROM THE BEGINNING IT FELT AS THOUGH THE CAR WAS UNEVEN EVEN WHEN NOT MOVING. AT THAT TIME I REQUESTED A WRITTEN EXPLANATION OF THIS PROBLEM AND TOLD MY RECORD AT THE DEALERSHIP WOULD SUBSTANTIATE THIS. ON THE NIGHT OF THE ACCIDENT I LEARNED BY REVIEWING COMPLAINTS FROM THE OFFICE OF DEFECT INVESTIGATIONS ON THE NHTSA WEB SITE THAT THE PROBLEMS HAVE BEEN KNOWN BY THE CORPORATE OFFICE OF LEXUS FROM AS EARLY AS JANUARY, 2002 IN REGARDS TO ALL OF THE ABOVE PROBLEMS. I ALSO FOUND OUT THERE HAVE BEEN TWO RECALLS ON THIS VEHICLE THAT I WAS NOT INFORMED ABOUT.
