I HAVE NOW SENT MY CAR IN FOR SERVICE TWICE TO LEXUS OF ORLANDO ABOUT UNEXPECTED SURGING OF THE VEHICLE AND VEHICLE HESITATION WHEN THE ACCELERATOR IS PRESSED. THIS IS AN INTERMITTENT AND DANGEROUS PROBLEM, AS I DO NOT KNOW WHEN IT WILL OCCUR. WHEN IT DOES OCCUR THE UPSHIFT IS HARSH, THE DOWNSHIFT DELAYED AS IF THE TRANSMISSION IS CONFUSED ABOUT THE DRIVER'S INTENTION, AND THERE IS PRONOUNCED HESITATION WHEN THE ACCELERATOR IS PRESSED. THIS LACK OF RESPONSIVENESS LEAVES BOTH THE VEHICLE AND PASSENGERS EXPOSED TO ACCIDENT AND INJURY. ON MY FIRST VISIT, I WAS TOLD THE VEHICLE COMPUTER WOULD BE RESET, AS THE VEHICLE LEARNS YOUR DRIVING STYLE IN THE FIRST 30 OR SO MILES, AND I MUST HAVE DRIVEN THE VEHICLE HARSHLY. THIS SO CALLED RESET DID NOTHING TO FIX THE PROBLEM; LESS THAN A WEEK LATER, I NARROWLY ESCAPED A CRASH AFTER MY CAR HESITATED WHILE CROSSING AN INTERSECTION. I PROMPTLY RETURNED THE VEHICLE TO THE DEALER FOR SERVICE. UPON COMPLETION OF THE SECOND SERVICE, WHICH INCLUDED A DRIVE WITH THE TECHNICIAN, LEXUS SERVICE NOW SAYS THESE PROBLEMS ARE INHERENT TO THE MODEL AND THEY CAN'T FIX THEM. IN ADDITION, I AM AWARE THAT NUMEROUS OWNERS FREQUENTLY COMPLAIN OF HESITATION AND SURGING IN 2002, 2003, AND 2004 MODELS AND MANY COMPLAINTS (OVER 100) OF THE SAME NATURE HAVE BEEN FILED WITH THE NHTSA. THIS STATEMENT IS TO ISSUE NOTICE THAT I AM NOT SATISFIED, AND THE PROBLEM HAS NOT BEEN FIXED.*AK

ON TWO SEPARATE OCCASIONS, I HAVE TAKEN MY 2003 LEXUS ES300 IN FOR SERVICE TO REPAIR A DEFECTIVE TRANSMISSION. I HAVE 23,511 MILES ON MY VEHICLE AND THE TRANSMISSION IS SHIFTING ERRATICALLY AND HESITATING. IT IS CAUSING UNSAFE DRIVING CONDITIONS. LEXUS DENIES ANY RESPONSIBILITY TO FIX THE PROBLEM.*AK

LEXUS ES300 2003 - EXTREMELY DANGEROUS SITUATION WHEN ACCELERATING FROM 5-10 MPH TO FULL ACCELERATION (PASSING/MERGING ONTO HIGHWAY FOR EXAMPLE). TRANSMISSION HESITATES A VERY LONG TIME (1-2 SECONDS) BEFORE KICKING IN. DEALER CLAIMS THIS IS A KNOWN PROBLEM BUT NOTHING IS BEING DONE ABOUT IT. RESEARCHING LEXUS FORUMS INDICATES THIS IS A WIDE SPREAD PROBLEM FOR 2002, 2003 YEARS AT LEAST. THE HESITATION IS EXTREMELY UNNERVING IN A HIGH STRESS MERGING ENVIRONMENT AT LEAST AND POTENTIALLY DANGEROUS ACCIDENT POTENTIAL AT WORSE.

LTR FM BRETT WOODY (TX) RE DANGEROUS DEFECTIVE TRANSMISSION SOFTWARE PROBLEMS IN THE 2002-2003 LEXUS ES300, REPLY ATTN JAN CROW/ HOUSTON OFC. *PH CONSUMER WOULD APPLY MORE AND MORE PRESSURE TO THE BRAKE PEDAL BUT THE VEHICLE WOULDN'T ACCELERATE. *PH THE TRANSMISSION FAILED TWICE. LEXUS HAD GIVEN THE CONSUMER A NEW VEHICLE AND IT HAD SIMILAR PROBLEMS. THE CONSUMER WAS ALMOST INVOLVED IN SEVERAL ACCIDENTS. ON NUMEROUS OCCASIONS, AFTER THE BRAKE PEDAL WAS TAPPED, THE VEHICLE WOULD ACCELERATE BUT THE RPM'S WOULD RISE AND THE VEHICLE WOULD BARELY MOVE. IN STOP IN GO TRAFFIC THE VEHICLE WOULD SURGE FORWARD. (IT FELT AS IF THE TRANSMISSION SLIPPED THEN THE SURGING OCCURRED) THERE WAS AN ANNOYING RATTLE IN THE CEILING CONSOLE. *SC UPDATED 7/5/12 *CN

THERE IS A DANGEROUS AND UNPREDICTABLE TENDENCY FOR THE VEHICLE ENGINE/TRANSMISSION COMBINATION TO ACCELERATE SUDDENLY AND UNEXPECTEDLY. THIS IS AN INTERMITTENT PROBLEM WHICH MAKES IT ESPECIALLY UNNERVING. IT IS MOST NOTICEABLE AT SPEEDS BELOW 40 MPH, WHEN FIRST SLOWING, FOLLOWED BY ACCELERATION. IT APPEARS TO BE EXACERBATE BY UNCERTAIN TRANSMISSION "HUNTING" FOR PROPER GEAR/ENGINE SPEED COMBINATIONS. THE SUDDEN ACCELERATION CAUSES A RAPID AND JERKY THROTTLE RESPONSE TO MILD ACCELERATOR PEDAL INPUT. I HAVE TAKEN THE CAR TO THE DEALER ON AT LEAST TWO OCCASIONS FOR THIS ISSUE. THE FIRST TIME, THE DEALER REPROGRAMMED THE TRANSMISSION. THE SECOND TIME, THE TECHNICIAN TESTED THE VEHICLE AND NOTE "NO PROBLEM FOUND". AT CURRENT MILEAGE OF 32,000, THE PROBLEM SEEMS TO BE WORSENING. THIS IS A DANGEROUS CONDITION THAT, IF LEFT UNDRESSED, IS LIKELY TO BE THE CAUSE OF AN ACCIDENT, SERIOUS INJURY OR MUCH WORSE. *JB

THE TRANSMISSION IN THIS CAR IS UNPREDICTABLE. IT JERKS, JUMPS AND ON OCCASION LURCHES AHEAD. IT WILL HESITATE WHEN STARTING FROM STAND STILL OR WHEN MOVING AHEAD AT VERY LOW SPEEDS. I HAVE REPEATEDLY TAKEN IT TO THE DEALER. THEY HAVE DONE 2 COMPUTER DOWN LOADS OF A SUPPOSED FIX. THE FIRST LASTED A DAY. I'VE BEEN TOLD TO USE ONLY PREMIUM FUEL, AS THIS WOULD HELP. I'VE USED PREMIUM SINCE THAT TIME WITH LITTLE CHANGE IN THE CARS PERFOMANCE. MY WIFE DOES NOT WANT TO DRIVE THE CAR BECAUSE OF A NEAR T-BONE IN A CROSS PATTERN TRAFFIC. I'VE HAD 4 SIMILAR EXPERINCES. THIS PROBEM BECAME APPARENT AT ABOUT 1000 TO 1200 MILES AND EXITS TODY AT ABOUT 4000 MILES. ALL OF THESE QUERKY PROBLEMS EXIST BELOW 40 MILES PER HOUR. IF YOU DRIVE VERY AGGRESSIVELY (STOMP ON THE ACCELERATOR)THEY AREN'T EVIDENT...TO SOME EXTE THE SAME IS TRUE IF YOU BARELY DEPRESS THE ACCELERATOR WHEN STARTING TO MOVE.

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.
