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 PURCHASED MY VEHICLE FROM CARMAX ABOUT 2.5 MONTHS AGO WITH AN EXTENDED WARRANTY. AFTER DRIVING MY VEHICLE DAILY BACK AND FORTH TO WORK, I NOTICED THE HESITATION WHILE COMING TO COMPLETE STOP OR A TRAFFIC LIGHT. THE RPM WOULD INCREASE WHILE THE TRANSMISSION WOULD HESITATE WHEN I PUSHED THE ACCELERATOR BETWEEN THE SPEEDS OF 10 - 35 MPH. AT FIRST SIGN, IT APPEARED THE TRANSMISSION WAS DEFECTED, SO I DECIDED TO TAKE IT TO CARMAX SERVICE CENTER. TWO DAYS LATER I RECEIVED MY 2003 LEXUS ES300 WITH A CLEAN SLATE (THE SERVICE TECHNICIANS INDICATED THE TRANSMISSION DID NOT INDICATED WEAR) AND I WAS TOLD TO BRING IT BACK IF I STILL HAD THE SAME PROBLEM. I AM TAKING MY VEHICLE TO THE SERVICE CENTER WITH MORE INFORMATION TOMORROW. LEXUS/TOYOTA NEEDS TO EITHER RECALL THESE VEHICLES TO FIX THIS ISSUE OR THEY WILL HAVE A MAJOR LAWSUITS FROM A LOT OF PEOPLE WITH A CLASS ACTION SUITE. THIS IS A VERY DANGEROUS SITUATION AND NEEDS TO BE ADDRESS FROM LEXUS/TOYOTA REPRESENTATIVES TO KEEP TOYOTA/LEXUS IN GOOD STANDINGS. AFTER READING OTHER COMPLAINTS, I AM REALLY NERVOUS ABOUT DRIVING MY VEHICLE AND I JUST PURCHASED IT. *TR

WE HAVE EXPERIENCED ON SEVERAL OCCASSIONS THAT VEHICLE HESITATES WHEN TRYING TO ACCELERATE AT STOP SIGN OR WHEN INITIALY IN START TO DRIVE AT ABOUT 20-30 MILES PER HOUR AT TIMES FOR FEW SECONDS & AT TIMES IT RATTLES 3-4 TIMES. THIS CAR WAS PURCHASED AS CERTIFIED PRE-OWNED FROM LEXUS DEALER IN EXCELLENT CONDITION IN 2006 THAT CAME WITH EXTENDED WARRANTY UPTO 75000 MILES BUT THIS PROBLEM STARTED WITH SLIGHT & SMOOTH JERK ABOUT 3 YEARS BACK, TOOK IT TO DEALER AFTER NOTICED FOR FEW TIMES TO DIAGNOSIS. AT FIRST INSTANCE THEY COULD NOT FEEL IT SINCE IT WAS NOT CONSISTENT BUT WHEN AGAIN COMPLAINED FOR SECOND TIME WAS TOLD THAT IT COULD BE FUEL INJECTORS CLOGED FOLLOWED BY OTHER LIST OF POTENTIAL SERVICE ITEMS WE WERE TALKING ABOUT $1000+ EXPENSE WHICH WE DENIED IT SINCE WE HAVE ALWAYS MAINTAINED OUR CAR GOOD & ALWAYS USE 93 OR 89 OCTAINE GAS WITH MAINTENANCE SERVICE AS RECOMMENDED. THIS ONE IS MY WIFE'S VEHICLE & USED TO COMMUTE TO WORK MOSTLY ON EXPRESS WAY. WE DO HAVE COUPLE OTHER ISSUES WITH THIS CAR BUT NOT AS IMPORTANT. NOW, LATELY THIS HESITATION FREQUENCY HAVE INCREASED & FROM WHAT I HEAR IS THAT WE ARE NOT ALONE AND THIS SEEMS TO BE AN ONGOING ISSUE WITH SOME OTHER ES300 OWNERS AS WELL. *TT

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

THE LEXUS ES300 HAS HAD A SERIOUS HESITATION PROBLEM SINCE DELIVERY IN MARCH 2003. I HAVE HAD IT IN FOR SERVICE SEVERAL TIMES BEFORE THE ACCIDENT COMPLAINING ABOUT THIS PROBLEM. ON MAY 8TH,2006, MY WIFE WAS TRYING TO MAKE A LEFT TURN AT AN INTERSECTION AND UPON ACCELERATING THROUGH THE TURN THE CAR HESITATED/LAGGED AND WAS STRUCK BY AN ONCOMING AUTO. AFTER CONTACTING LEXUS DIRECT, THEY CAME OUT TO TEST DRIVE THE AUTO. I WAS CONTACTED SEVERAL DAYS LATER AND WAS TOLD THAT MY LEXUS HAS NO PROBLEM. SINCE THIS PROBLEM STILL EXISTS, I TOOK THE CAR BACK IN FOR SERVICE ON MAY 26TH, 2006 AND AGAIN WAS TOLD THAT MY CAR HAD ALREADY RECEIVED A TRANSMISSION COMPUTER UPDATE AND THEIR FINAL WORDS WERE "VEHICLE IS OPERATING AS DESIGNED AT THIS TIME". THIS CAR STILL HAS THE PROBLEM. *NM

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.
