I PURCHASED A USED 2003 LEXUS ES30FROM USED CAR DEALER. AFTER A COUPLE DAYS OF DRIVING IT I NOTICED IT WAS SHIFTING GEARS INNORMALLY. IT WOULD SURGE UP TO 4000RMP BEFORE SHIFTING TO 2ND GEAR AND AT ONE POINT WASN'T MOVING WHILE I HIT THE GAS THE ACCELERATION VERY FAST OUT OF NOWHERE. MY MOTHER ALSO HAD THIS SAME YEAR MAKE AND MODEL VEHICLE A FEW YEARS BACK AND IT HAD THE SAME PROBLEM BEFORE THE TRANSMISSION WENT OUT. I DID SOME RESEARCH ONLINE AND FOUND MANY OTHER LEXUS CUSTOMERS EXPERIENCED THE SAME PROBLEM. I FOUND A WEB SITE THAT CLAIMED THAT THERE WAS A TSB PUT OUT FOR THIS VEHICLE AND THAT THE LEXUS/TOYOTA DEALERSHIPS WOULD FIX THIS PROBLEM WITH AN UPGRADE. I WAS WONDERING IF THIS UPGRADE IS STILL AVAILABLE AND IF MY VEHICLE WOULD QUALIFY? AND IF SO HOW WOULD I GO ABOUT THIS PROCESS.

I WAS PULLING OUT OF THE GARAGE SLOWLY TO PAUSE ON THE DRIVEWAY TO CLOSE THE GARAGE DOOR AND WHEN I STEP ON THE GAS IN REVERSE THE CAR FLEW OUT OF THE GARAGE AND I COULDN'T STOP IT WITH THE BRAKES. THERE WAS A SMALL ROOFING ACROSS THE STREET WHICH STOPPED THE CAR. NO ONE WAS NEARBY SO NO ONE WAS HURT. THE ACCELERATOR SEEMED STUCK FOR THIS INCIDENT TO HAPPEN. HOWEVER, LEXUS HAD AN INSPECTOR CHECK THE CAR AND DIDN'T FIND ANYTHING WRONG THAT SHOWED ON THE COMPUTER SO THEY WON'T TAKE RESPONSIBILITY FOR THIS OCCURRENCE AND THEY CLOSED THE CASE. I TRIED TO SPEAK TO SOMEONE TO SEND THIS TO ARBITRATION BUT NO ONE WOULD SPEAK TO ME. CASE CLOSED. THIS WAS A VERY FRIGHTENING EXPERIENCE WITH NO CONTROL IN THE CAR. *TR

MY CAR OVER THE LAST COUPLE OF YEARS STARTED EXPERIENCING ABNORMAL ACCELERATION . THERE WERE TIMES IT USES TO SURGE OR SOUND LIKE IT WAS RAMPING UP TO GO FAST, EVEN WITH MY FOOT ON THE BREAK, YOU COULD HEAR THE ACCELERATION TRYING TO RAMP UP LIKE IF MY FOOT WASN'T ON THE BREAK IT WOULD JUST TAKE OFF. THEN THE OPPOSITE STARTED TO HAPPEN. MY CAR IDLE WOULD JUST DROP AND BASICALLY WHEN I WOULD GO TO TAKE OFF FROM A STOP, THE CAR WOULD NOT ACCELERATE AT ALL. IT WAS INCONSISTENT SO SOMETIMES IT WOULD OVER ACCELERATE AND SOMETIMES UNDER. THERE WAS NO ACCIDENT, BUT I'VE HAD A FEW CLOSE CALLS AND SOME PEOPLE TO GET AGGRAVATED AT MY CAR.I TOOK IT TO THE PEP BOYS THEY THOUGHT IT NEEDED FLUSHED MAYBE INJECTION CLEANING LIKE ALL OTHER SCENARIOS I AM JUST NOW READING ABOUT. AFTER THAT, IT SEEMED TO WORK FOR A SHORT WHILE, BUT THEN THE ISSUE START OCCURRING AGAIN. I HAD MY SPARK PLUGS CHANGED AND NEW COILS , NEW AIR FLOW HOSE TO MAKE SURE THERE WAS NO APPARENT REASON FOR THE ISSUES. THE PROBLEM STILL EXIST SO I TOOK IT TO A LEXUS DEALERSHIP WHERE THEIR SUGGESTION IS THE PROBLEM IS IN THE THROTTLE BOTTLE. IT SEEMS TO BE A COMMON LINK WITH THE ACCELERATION ISSUE AND THE SAME SUGGESTIONS ARE MADE FROM THE MECHANICS TO FUEL INJECTION , TO SPARK PLUGS TO SEEMING LIKE TRANSMISSION ISSUE AND ITS THE THROTTLE BODY / PLEASE HAVE LEXUS FIX THESE ISSUES.. THEY ARE EXPENSIVE FOR THE OWNER TO HAVE TO GO THROUGH ALL THE TROUBLE SHOOTING AND RANGE OF . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

ON 9/4/2011 AT APPROX. 1: 41 PM, I WAS PULLING MY 2003 LEXUS ES300 (WITH MY FOOT ON THE BRAKE) INTO A SHOPPING CENTER PARKING SPACE WHEN IT SUDDENLY SURGED, THEN ACCELERATED OVER THE CURB AND ONTO A SIDEWALK WHERE PEOPLE WERE DINING AT TABLES. AS THE CAR ACCELERATED OVER THE CURB, I PUSHED HARDER ON THE BRAKE AND TRIED TO STEER THE CAR AWAY FROM THE DINERS. AS THE LEXUS GOES OVER THE CURB AND ONTO THE SIDEWALK, THE CAR CONTINUED TO ACCELERATE LIKE IT WAS BEING PULLED, AND THE DRIVER'S SIDE BUMPER HIT A TABLE OF DINERS. THREE PEOPLE ARE INJURED; ONE WITH COMPOUND FRACTURE. THE CAR CONTINUED TO ACCELERATE AS I CONTINUED TO PUSH ON THE BRAKE, TRYING TO WILL THIS CAR TO STOP. IT HIT TABLES AND CHAIRS AS PEOPLE JUMPED OUT OF THE WAY OF THIS RUNAWAY CAR! THE CAR DEFLECTED OFF A BUILDING AND CAME TO A STOP ON THE SIDEWALK. MY FOOT WAS STILL ON THE BRAKE. TIRE MARKS FROM THE BRAKING WERE VISIBLE ON THE CURB AND SIDEWALK AS LOCAL NEWS STATIONS RECORDED AND AIRED. AIRBAGS DID NOT DEPLOY. THE WEATHER AND VISIBILITY WERE CLEAR. AROUND 10/4/2011, ONE MONTH AFTER THE WRECK, A TOYOTA INVESTIGATOR INSPECTED THE CAR'S ACCELERATOR PEDAL AND FOUND IT "OPERATED SMOOTHLY AND RETURNED TO ITS IDLE POSITION WITHOUTANY BINDING OR STICKING...[IT WAS] CORRECTLY ALIGNED...NO DAMAGE OBSERVED. THE ELECTRICAL CONNECTOR WAS IN PLACE AND SECURE....A DIAGNOSTIC SYSTEM CHECK SHOWED THAT THERE WERE NO TROUBLE CODES RELATING TO THE OPERATION OF THE VEHICLE." BUT MY FOOT WAS ON THE BRAKE. AS OF 3/12/2012: PROPERTY DAMAGE: $20,000. LEXUS BODY DAMAGE:$9000. PERSONAL INJURIES: ONE SETTLED, ONE COUNTERED, ONE TALKING WITH A PERSONAL INJURY LAWYER. I NO LONGER OWN THE CAR. I WAS TERRIFIED TO DRIVE IT. *TR

2003 ES 300 - TRANSMISSION ISSUES: I HAVE BEEN EXPERIENCING HESITATION UPON ACCELERATION ALMOST EVERY TIME, ALONG WITH HARD SHIFTING 50% OF THE TIME. THE ACCELERATION HESITATION CAN BE SCARY IF I'M TRYING TO ENTER THE HIGHWAY, OR TURNING LEFT. THE HARD SHIFTING FEELS LIKE I GOT HIT FROM BEHIND. BOTH PROBLEMS HAVE BEEN GOING ONGOING FOR YEARS AND LEXUS DEALER HAS NEVER BEEN ANY HELP. I READ MANY OF THE ONLINE FORUMS AND FOUND THAT BOTH OF THESE PROBLEMS ARE VERY COMMON AS ARE THEIR RESULTS FOR GETTING THESE ISSUES FIXED - NOT MUCH LUCK FROM THE DEALER - "IT WORKS AS IT IS DESIGNED". REALLY? LEXUS NEEDS TO STAND BEHIND THEIR PRODUCT. I CAN'T BELIEVE HOW MANY COMPLAINTS I HAVE READ (100S) AND THEIR HASN'T BEEN A RECALL. HOW DOES A CONSUMER GO ABOUT PUSHING FOR A RECALL, OR CLASS ACTION OR WILL THE LEMON LAW WORK? *KB

Status: closed (inferred from source dates) · Vehicle Speed Control

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.
