I WAS ABLE TO GET MY CAR TO THE RIGHT AND GET OFF THE FREEWAY TO A GAS STATION. AS I WAS SLOWING TO A STOP, THE CAR WAS SHUDDERING BEFORE IT CAME TO A COMPLETE STOP.

I FOLLOWED THE INSTRUCTIONS IN THE MANUAL AND WAS ABLE TO DRIVE THE CAR AT LOWER SPEED TO GET HOME AND THEN GET IT TO THE DEALER THE NEXT MORNING.*JB

I WAS TOLD THERE WAS NOTHING WRONG SEVERAL TIMES AND MORE RECENTLY HAVE BEEN TOLD IT IS A DESIGN FLAW IN THE COMPUTER-CONTROLLED ACCELERATOR AND CANNOT BE FIXED. I HAVE SEVERAL TIMES HAD A CLOSE CALL ON THE FREEWAY WHEN I NEEDED TO ACCELERATE QUICKLY AND THE CAR HESITATED BEFORE ACCELERATING. I HAVE NOT HAD AN ACCIDENT, BUT HAVE BEEN VERY FRIGHTENED BY THE DELAY IN PERFORMANCE. I HAVE HAD 2 PREVIOUS LEXUS ES 300'S THAT DID NOT HAVE THIS PROBLEM. *NM

ON JAN 20, 2005 AT ABOUT 7:30PM I WAS RETURNING FROM WORK DRIVING MY LEXUS 2003. JUST BEFORE REACHING MY HOME, I TURNED RIGHT INTO NOTLEY ROAD FROM STONE GATE DRIVE AT SILVER SPRING, MD AFTER STOPPING AT THE STOP SIGN. BEFORE I REALIZED, THE CAR KNOCKED OVER THE MAIL BOX OF THE HOUSE ON THE RIGHT SIDE AND STARTED RACING ON THE YARD OF THE HOUSE. NEXT THE CAR KNOCKED DOWN THE STREET LIGHT, CROSSED A ROAD AND RACED TOWARDS A TREE. ALTHOUGH I APPLIED, THE BRAKES WERE NOT WORKING. ULTIMOTELY THE CAR CRASHED ON TO A TREE, TURNED OVER AND I WAS LUCKY ENOUGH TO CRAWL OUT OF THE CAR WITH MUCH EFFORT. I WAS TAKEN TO THE MONTGOMERY COUNTY GENERAL HOSPITAL BY AMBULANCE AND AFTER BEING EXAMINED BY THE PHYSICIAN AND XRAYS I WAS RELEASED. THE CAR WAS ULTIMATELY TOWED TO LEXUS BODY SHOP AND WAS PRONOUNCED A TOTAL LOSS I FEEL THAT THE LEXUS TOOK OFF ON ITS OWN WHEN I TURNED RIGHT FROM A STOP SIGN INTO THE NOTLEY ROAD DAMAGING PROPERY AND ULTIMOATELY CRASHING ON TO A TREE. BECAUSE THERE WAS SNOW ON THE YARD, I WAS ABLE TO VIDEOTAPE THE TRACK MARKS MADE BY THE CAR FROM THE BEGINNING TO THE END OF THE CRASH. I HOPE THAT YOU WILL INVESTIGATE THIS INCIDENT AND GIVE ME SOME REPORT.*AK

THE OFFICE OF DEFECTS INVESTIGATION (ODI) OPENED DP09-001 ON APRIL 8, 2009, TO EVALUATE A DEFECT PETITION REQUESTING ADDITIONAL INVESTIGATION OF POTENTIAL THROTTLE CONTROL SYSTEM DEFECTS UNRELATED TO FLOOR MAT INTERFERENCE WITH ACCELERATOR PEDALS IN MODEL YEAR (MY) 2007 LEXUS ES 350 VEHICLES.THE PETITIONER REFERENCED AN EARLIER ODI INVESTIGATION CONCERNING FLOOR MAT INTERFERENCE WITH ACCELERATOR PEDAL RETURN (PE07-016/EA07-010), WHICH HE STATED WAS TOO NARROW IN SCOPE AS IT DID NOT INCLUDE ALL INCIDENTS OF UNWANTED ACCELERATION AND CONSIDER ALL POTENTIAL CAUSES OF VEHICLE SPEED CONTROL CONCERNS.THE PETITION ALSO REQUESTED AN INVESTIGATION OF MY 2002-2003 LEXUS ES300 FOR THOSE 'LONGER DURATION INCIDENTS INVOLVING UNCONTROLLABLE ACCELERATION WHERE BRAKE PEDAL APPLICATION ALLEGEDLY HAD NO EFFECT' THAT WERE DETERMINED NOT TO BE WITHIN THE SCOPE OF INVESTIGATION PE04-021. AS BACKGROUND, THE PETITIONER OWNS A MY 2007 LEXUS ES350 THAT ALLEGEDLY EXPERIENCED AN UNWANTED AND UNCONTROLLED ACCELERATION EVENT (ODI COMPLAINT NUMBER 10261660).TOYOTA CONCLUDED THAT THE INCIDENT WAS CAUSED BY AN UNSECURED FLOOR MAT. TO ASSESS THE PETITIONER'S REQUEST, ODI INTERVIEWED THE PETITIONER, INSPECTED HIS VEHICLE, REVIEWED INFORMATION SUBMITTED BY TOYOTA, REVIEWED OWNER COMPLAINTS ALLEGING INCIDENTS OF UNWANTED ACCELERATION IN THE SUBJECT VEHICLES AND MATERIAL RELATED TO THE INVESTIGATIONS CITED BY THE PETITIONER.ODI IDENTIFIED 64 COMPLAINTS ALLEGING INCIDENTS OF UNWANTED ACCELERATION IN MY 2007 LEXUS VEHICLES, RESULTING IN 8 CRASHES AND 15 INJURIES.ODI'S ANALYSIS OF THESE COMPLAINTS DETERMINED THAT 50 (78%) INVOLVED INCIDENTS OF FLOOR MAT INTERFERENCE, INCLUDING 7 (88%) OF THE CRASHES AND ALL 15 INJURIES.THEREFORE, ODI'S ANALYSIS FOUND THAT THE ONLY DEFECT TREND RELATED TO VEHICLE SPEED CONTROL IN THE SUBJECT VEHICLES INVOLVED THE POTENTIAL FOR ACCELERATOR PEDALS TO BECOME TRAPPED NEAR THE FLOOR BY OUT-OF-POSITION OR INAPPROPRIATE FLOOR MAT INSTALLATIONS. ON OCTOBER 5, 2009, TOYOTA INITIATED A SAFETY RECALL (RECALL 09V-388) TO ADDRESS CONCERNS WITH POTENTIAL ACCELERATOR PEDAL ENTRAPMENT BY FLOOR MATS IN APPROXIMATELY 3.8 MILLION VEHICLES, INCLUDING THE SUBJECT VEHICLES.EXCEPT INSOFAR AS THE PETITIONER'S CONTENTIONS RELATE TO THAT RECALL, THE FACTUAL BASES OF THE PETITIONER'S CONTENTIONS THAT ANY FURTHER INVESTIGATION IS NECESSARY ARE UNSUPPORTED. IN OUR VIEW, ADDITIONAL INVESTIGATION IS UNLIKELY TO RESULT IN A FINDING THAT A DEFECT RELATED TO MOTOR VEHICLE SAFETY EXISTS OR A NHTSA ORDER FOR THE NOTIFICATION AND REMEDY OF A SAFETY-RELATED DEFECT, AS ALLEGED BY THE PETITIONER, AT THE CONCLUSION OF THE REQUESTED INVESTIGATION.THEREFORE, IN VIEW OF THE NEED TO ALLOCATE AND PRIORITIZE NHTSA'S LIMITED RESOURCES TO BEST ACCOMPLISH THE AGENCY'S SAFETY MISSION, THE PETITION IS DENIED.THIS ACTION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT A SAFETY-RELATED DEFECT DOES NOT EXIST.THE AGENCY WILL TAKE FURTHER ACTION IF WARRANTED BY FUTURE CIRCUMSTANCES.PLEASE SEE THEFEDERAL REGISTER NOTICE FOR FURTHER DETAILS.

IN A LETTER DATED JULY 8, 2005, AND AFTER EXPERIENCING TWO INCIDENTS (AND ONE CRASH) WHERE HE ALLEGES HIS MODEL YEAR (MY) 2002 CAMRY ACCELERATED WITHOUT DRIVER INPUT, MR. JORDAN ZIPRIN PETITIONED THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION?S (NHTSA) OFFICE OF DEFECTS INVESTIGATION (ODI) TO COMMENCE A PROCEEDING TO DETERMINE THE EXISTENCE OF A DEFECT WITHIN THE ETC SYSTEM IN MY 2002 TO 2005 TOYOTA AND LEXUS VEHICLES, OR TO REOPEN A PRIOR INVESTIGATION PRELIMINARY EVALUATION (PE) 04-021.IN A LETTER DATED AUGUST 18, 2005, MR. ZIPRIN AMENDED HIS PETITION TO INCLUDE ALLEGATIONS OF INTERRELATED BRAKE AND ACCELERATION PROBLEMS THAT ALLEGEDLY RESULT IN INAPPROPRIATE AND UNCONTROLLABLE VEHICLE ACCELERATIONS.THE 1172 VEHICLE OWNER QUESTIONNAIRE REPORTS CITED BY THE PETITIONER INVOLVE 4 LEXUS AND 15 TOYOTA MODELS DEFINING A POPULATION OF 7 MILLION VEHICLES.THE REPORTS TYPICALLY ALLEGED A DEFECT IN THE BRAKE SYSTEM, THE THROTTLE CONTROL SYSTEM, OR A COMBINATION OF BOTH SYSTEMS.IN ITS REVIEW OF THE REPORTS, ODI A) FAILED TO FIND EVIDENCE TO SUPPORT THE EXISTENCE OF A BRAKE RELATED DEFECT IN THE CITED MODELS, AND B) DETERMINED THAT MANY CITED PRODUCTS WERE NOT EQUIPPED WITH ETC.ACCORDINGLY, ODI RESTRICTED ITS ANALYSIS TO THE 432 PETITIONER REPORTS INVOLVING MY 2002 TO 2005 CAMRY, SOLARA, AND ES MODELS (ALL EQUIPPED WITH ETC) THAT ALLEGED AN ABNORMAL THROTTLE CONTROL EVENT (SEE THE JANUARY 3, 2006 FEDERAL REGISTER NOTICE FOR FURTHER DETAILS).ABOUT 40% OF THE 432 REPORTS INVOLVE A DRIVEABILITY CONCERN WHERE THE OPERATOR INTENTIONALLY APPLIES THE THROTTLE PEDAL, IN EXPECTATION THAT THE VEHICLE WILL ACCELERATE, AND THEN EXPERIENCES A DELAY OR HESITATION IN VEHICLE RESPONSE.THESE REPORTS INVOLVE VEHICLE RESPONSE TO INTENTIONAL DRIVER COMMANDS WHICH ODI CONSIDERS UNRELATED TO THE ALLEGATIONS RAISED BY THE PETITIONER.THEREFORE, THE REPORTS DO NOT PROVIDE SUPPORT FOR THE INVESTIGATION REQUESTED.ABOUT 20% OF THE REPORTS INVOLVE INCIDENTS WHERE OPERATORS ALLEGE VEHICLE ACCELERATION WITHOUT DRIVER INPUT AND AN INABILITY OF THE BRAKE SYSTEM TO CONTROL THE VEHICLE WHEN APPLIED.NEITHER THE REPORTS, NOR THE INTERVIEWS CONDUCTED BY ODI, IDENTIFIED ANY VEHICLE-BASED CAUSE TO EXPLAIN THE INCIDENTS OR DISCLOSED EVIDENCE TO SUPPORT THAT A FAILURE OF THE BRAKE OR THROTTLE CONTROL SYSTEM HAD OCCURRED.BECAUSE THESE REPORTS DO NOT INDICATE A DISTINCT SAFETY DEFECT FOR INVESTIGATION, THE REPORTS DO NOT PROVIDE SUPPORT FOR THE INVESTIGATION REQUESTED BY THE PETITIONERTHE REMAINING REPORTS (~ 40%, SIMILAR TO THE PETITIONER?S AND THOSE OF PE04-021) TYPICALLY DESCRIBE INCIDENTS WHERE A VEHICLE IS BEING MANEUVERED AT SLOW SPEED IN A CLOSE QUARTER SITUATION AT WHICH POINT THE OPERATOR ALLEGES THAT THE VEHICLE ACCELERATES WITHOUT DRIVER INPUT AND CRASHES.IN THE AFTERMATH, OPERATORS ARE UNSURE OF WHETHER THE BRAKES WERE APPLIED OR NOT, SOMETIMES STATING THERE WAS INSUFFICIENT TIME TO USE THE BRAKE; A CRASH OCCURRED AND THE OPERATOR BELIEVES AN UNCOMMANDED ACCELERATION CAUSED IT.IN SPITE OF THE EFFORT EXPENDED DURING PE04-021 AND DURING THIS ANALYSIS, ODI HAS NOT IDENTIFIED ANY VEHICLE-BASED CAUSE TO EXPLAIN THE REPORTS, OR UNCOVERED ANY EVIDENCE TO INDICATE THAT A THROTTLE CONTROL SYSTEM FAILURE OCCURRED.THEREFORE, THE REPORTS HAVE AMBIGUOUS SIGNIFICANCE AND DO NOT CONSTITUTE A BASIS ON WHICH ANY FURTHER INVESTIGATIVE ACTION IS WARRANTED.BASED ON THE ANALYSIS CONDUCTED, IT IS UNLIKELY THAT THE NHTSA WOULD ISSUE AN ORDER FOR THE NOTIFICATION AND REMEDY OF A SAFETY RELATED DEFECT AT THE CONCLUSION OF THE INVESTIGATION REQUESTED IN THE PETITION.CONSEQUENTLY, IN VIEW OF THE NEED TO ALLOCATE AND PRIORITIZE NHTSA?S LIMITED RESOURCES T

THE POPULATION NUMBER NOTED ABOVE IS ESTIMATED.IN THE JANUARY 15TH, 2004 PETITION REQUEST LETTER TO THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION (NHTSA), THE PETITIONER IDENTIFIED 37 VOQ COMPLAINTS AS RELATED TO VEHICLE SPEED CONTROL ISSUES SIMILAR TO THOSE THE PETITIONER ALLEGEDLY EXPERIENCED IN THEIR OWN VEHICLE ON MULTIPLE OCCASIONS (AS DESCRIBED IN THE PETITION REQUEST LETTER).DURING IT'S CONSIDERATION OF THE REQUEST, THE OFFICE OF DEFECTS INVESTIGATION (ODI) REVIEWED THE 37 COMPLAINTS AND CONCLUDED THAT 34 OF THE COMPLAINTS DID NOT INVOLVE A THROTTLE CONTROL ISSUE AS DESCRIBED AND ALLEGED BY THE PETITIONER; THREE VOQS (ONE OF WHICH IS THE PETITIONER'S) DO ALLEGE A THROTTLE CONTROL ISSUE.HOWEVER, THE THROTTLE CONTROL ISSUES ALLEGED BY THE PETITIONER ARE SIMILAR TO THOSE ALLEGED IN THE SUPPORTING VOQS FOR PRELIMINARY EVALUATION PE04-021 WHICH INVOLVES THE THROTTLE CONTROL SYSTEM ON MODEL YEAR 2002 AND 2003 TOYOTA CAMRY AND CAMRY SOLARA MODELS.BASED ON ODI'S REVIEW OF AVAILABLE SERVICE INFORMATION, IT APPEARS THE THROTTLE CONTROL SYSTEM MANUFACTURED ON THE LEXUS ES300 MODELS IS THE SAME AS, OR SIMILAR TO, THE THROTTLE CONTROL SYSTEM USED ON THE TOYOTA CAMRY AND CAMRY SOLARA MODELS.ACCORDINGLY, THE ES300 MODELS WILL BE ADDED TO THE SCOPE OF PE04-021 AND THE PETITION IS GRANTED.
