THE FIRST TIME MY ECU FAILED WAS WHEN I WAS PARKED I WANT TO DRIVE AND THE ENGINE WOULD NOT GO ABOVE 1000RMPS. I GOT THE ECU REPLACED THIS WAS AROUND 2013. THE SECOND TIME WAS A MONTH AGO. I WAS DRIVING HOME FROM WORK HAD A HUGE THUD IN THE ENGINE AND THE SAME THING MY CAR COULD NO LONGER GO ABOVE 1000RPMS AND COULDN'T GET THREW THE INTERSECTION. THE CAR BEHIND ME HAD TO SLAM ON THERE BREAKS BECAUSE MY CAR HAD LOST ALL POWER. I MADE IT HOME AND WAS ABLE TO GET A TOW TRUCK. BY THE TIME THE TOW TRUCK ARRIVED THE CAR WOULD START BUT THEN COMPLETELY DIE. TOOK IT TO A MECHANIC THEY HAD IT FOR A WEEK SAID IT FIXED ITSELF. ONE HOUR AFTER I GOT IT THE CAR STARTED TO ACT UP AGAIN. THE CAR IS BACK IN THE SHOP. THEY HAD TO SEND THE ECU OUT TO GET REPAIRED. I DID SOME RESEARCH AND APPARENTLY THE PARTS LEXUS USED ON THE ECU ARE FAULTY AND LEEK. CAUSING THE MOTHERBOARD TO SHORT. I STILL HAVE NOT GOTTEN MY CAR BACK AND DON'T KNOW IF THE CAR WILL BE FIXED ONCE THEY GET THE COMPUTER BACK. PLEASE RESEARCH MORE AS THIS IS NOT A CHEAP FIX AND FOR IT TO HAPPEN TWICE....WHICH I'M SURE YOU ALREADY KNOW IS NOT SOMETHING COMMON TO HAVE TO REPAIR ON A CAR LET ALONE TWICE. WILL SEND MORE DOCUMENTATION ONCE I GET MY CAR BACK. OR FEEL FREE TO CONTACT ME.
NHTSA complaint #10957724 — an unverified report by a vehicle owner.
TL* THE CONTACT OWNED A 1993 LEXUS LS400. WHILE DRIVING AT A LOW RATE OF SPEED, THE VEHICLE ACCELERATED AT A HIGH RATE OF SPEED WHEN THE BRAKE PEDAL WAS DEPRESSED. AS A RESULT, THE VEHICLE DROVE OVER A CURB AND CRASHED UP A SLOPE NEAR A WOODED AREA. THERE WERE NO INJURIES AND A POLICE REPORT WAS NOT FILED. IN ADDITION, THERE WAS AN ABNORMAL NOISE HEARD NEAR THE ENGINE COMPARTMENT AND FRONT END OF THE VEHICLE AS THE VEHICLE SURGED AT AN EXTREMELY HIGH RATE OF SPEED. THE FAILURE WAS REPORTED TO THE INSURANCE COMPANY AND THE MANUFACTURER. THE VEHICLE WAS DESTROYED AND TOWED TO A COLLISION CENTER. THE CONTACT WAS WAITING ON A RESPONSE FROM THE MANUFACTURER REGARDING THE UNINTENDED ACCELERATION FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 201,600.
NHTSA complaint #10906939 — an unverified report by a vehicle owner.
IN APPROXIMATELY 1995, I EXPERIENCED THE "SUDDEN ACCELERATION" PROBLEM TWICE WITH MY LEXUS LS. AT THE TIME, NO ONE HAD EVER HEARD OF IT AND THE DEALER SAID HE COULD NOT REPRODUCE IT AND COULD DO NOTHING. AFTER THAT I WAS MORE CAREFUL WITH THE FLOOR MATS AND THOUGHT I HAD SOLVED THE PROBLEM. FOR THE LAST 7 TO 8 YEARS, THE CAR SUDDENLY SLOWS AND STALLS. I HAVE REPEATEDLY COMPLAINED TO NEW COUNTRY LEXUS BUT THEY JUST SAY THAT THEY CANNOT REPRODUCE THE PROBLEM AND DON'T KNOW WHAT IT IS. IN JUNE, IT HAPPENED AGAIN AND I HAD TO BE TOWED BY AAA. AT THIS TIME I RESEARCHED "LEXUS LS STALLING PROBLEM" AND GOT HUNDREDS OF HITS. ONE LEXUS SITE PERFECTLY EXPLAINED THE PROBLEM, HOW TO REPRODUCE IT AND HOW TO FIX IT. THE POSTING ON THE LEXUS SITE WAS DATED 2005, TEN YEARS AGO. THE TOW TRUCK DRIVER REPRODUCED THE PROBLEM WITHIN AN HOUR BUT NEW COUNTRY LEXUS WOULD NOT SELL HIM THE REQUIRED RESISTOR TO FIX IT. I TOOK THE CAR TO NEW COUNTRY LEXUS, JUST NORTH OF ALBANY NY, AND THEY HAVE HAD IT SINCE JUNE. THEY KEEP SAYING THAT THEY CANNOT REPRODUCE THE PROBLEM. THEY KEEP TELLING ME THAT THEY CANNOT REPRODUCE THE PROBLEM BUT I KEEP GIVING THEM THE PRINT-OUT FROM THE LEXUS SITE AND THE BILL FROM THE TOWING COMPANY EXPLAINING EXACTLY HOW TO REPRODUCE AND FIX THE PROBLEM. FINALLY YESTERDAY JOE MORAN SAID THAT HE COULD FIX IT BUT "AS SOON AS ANYONE BRINGS UP ANYTHING TO DO WITH SUDDEN ACCELERATION" I AM TOLD TO STOP AND DO NOTHING." HE SAID "IT IS NOT IN THE BEST INTEREST OF THE COMPANY TO FIX IT." THEY CLEARLY SEEMED TO BE TELLING ME THAT THIS RESISTOR (OR SENSOR) IS PART OF THE RAPID ACCELERATION PROBLEM WITH TOYOTA VEHICLES AND, ALTHOUGH MY VEHICLE IS NOT ON THE LIST OF VEHICLES INDICATED FOR A "SPECIAL PROTOCOL," THIS PARTICULAR PART IS TRACED TO THE RAPID ACCELERATION AND THEY WANT NOTHING TO DO WITH IT.
NHTSA complaint #10764167 — an unverified report by a vehicle owner.
TWICE, WITH TWO DIFFERENT DRIVERS, THIS VEHICLE HAS ACCELERATED/SURGED AT A STOP. THE VEHICLE WAS ABLE TO BE HELD STEADY BY PRESSING THE BRAKE AS HARD AS POSSIBLE, BUT VEHICLE STILL SURGED AND TRIED TO MOVE FORWARD. ON THE FIRST INCIDENT, THE VEHICLE WAS PUT IN NEUTRAL AND CONTINUED TO REV MOMENTARILY. AFTER THE FIRST INCIDENT, THE LEXUS OEM FLOOR MAT (STANDARD, NOT ALL SEASON) WAS REMOVED. THE SAME EVENT OCCURRED AGAIN TONIGHT WITH A DIFFERENT DRIVER AND THE FLOOR MAT STILL REMOVED. I AM QUITE CONCERNED THIS MAY BE RELATED TO OTHER TOYOTA RECALLS.
NHTSA complaint #10672882 — an unverified report by a vehicle owner.
AS I WAS DRIVING, MY VEHICLE STARTED ACCELERATING ON IT'S OWN. WHEN I HAD PREVIOUSLY CHECKED THE SPEED ODOMETER IT SAID 50. ALL OF A SUDDEN THE VEHICLE STARTED GAINING SPEED. I TOOK MY FOOT OFF OF THE GAS PEDAL AND THE SPEED KEPT ACCELERATING. I PRESSED THE BRAKES AND THE BRAKES DID NOT WORK! THE VEHICLE KEPT ACCELERATING. I SAW A SIDE ROAD AND TURNED ONTO IT. I KEPT TRYING TO STOP THE VEHICLE AND IT KEPT GOING. I THOUGHT TO PULL THE EMERGENCY BRAKE AND IT SLOWED THE VEHICLE CONSIDERABLE, BUT IT KEPT MOVING. THE ENGINE CONTINUED TO ACCELERATE. I KEPT PUMPING THE BREAKS WITH THE EMERGENCY BRAKE ON AND THE CAR WAS STILL MOVING. IT FINALLY STOP, BUT THE ENGINE WAS STILL ACCELERATING. I PUT THE VEHICLE IN PARK AND THE MORE THE ENGINE ACCELERATED. I PUT BACK IN DRIVE AND IT CONTINUED TO ACCELERATE. THE VEHICLE STARTED SMOKING. I DIDN'T KNOW WHAT TO DO OR WHAT WAS GOING TO HAPPEN TO THE VEHICLE. I TOLD MY SONS TO GET OUT OF THE CAR. I TURN THE ENGINE OFF, THE CAR JUMPED AND I RAN AWAY FROM THE CAR. THE VEHICLE WAS STILL SMOKING. I CALLED 911. THE CAR STOPPED SMOKING AND REMAINED IN PLACE. MY HUSBAND CAME AND STARTED THE VEHICLE IT ACCELERATED AND HE PRESSED THE GAS PEDAL AND IT STOPPED. I DROVE THE CAR HOME AND PARKED IT. I AM NOT DRIVING THE VEHICLE AND THIS IS THE REASON THAT I HAVE NOT ENTERED A VIN NUMBER.

NHTSA complaint #10463436 — an unverified report by a vehicle owner.
I AM REPORTING THIS BECAUSE IT MIGHT PROVIDE A CLUE TO THE TOYOTA RACING ENGINE PROBLEM. ON EACH OF TWO DAYS BEFORE I TOOK MY 1999 LEXUS 400 TO THE DEALER FOR REPAIRS, THE ENGINE WOULD RACE AT AN ESTIMATED 4,000+ RPMS AND EMITTED A GRINDING SOUND AS THE CAR WAS STARTED. AFTER TURNING OFF THE ENGINE WITH THE KEY, THE CAR WOULD RESTART WITHOUT A PROBLEM. STRANGELY, THE DEALER DID NOT RECORD THIS PARTICULAR COMPLAINT, BUT STATED THAT DIAGNOSIS REVEALED THAT STARTER WAS FAILING. I WAS CHARGED $990 FOR REPLACEMENT AND REPAIRS. I COULD NOT GET A SATISFACTORY ANSWER AS TO WHY A FAULTY STARTER WOULD CAUSE THE ENGINE TO RACE. I HAVE DRIVEN THE CAR OVER 10,000 MILES SINCE THEN WITHOUT A PROBLEM.
NHTSA complaint #10319258 — an unverified report by a vehicle owner.
WHILE DRIVING MY 1997 LEXUS LS400 IN CA ON THE 605 FWY, WEST TOWARD 210 FWY, ALL SYSTEMS ON THE CAR LOCKED (STEERING WHEEL, BRAKES, GAS PEDAL) AS I WAS CHANGING LANES. I HAD NO CONTROL OF THE CAR AND AFTER SPINNING SEVERAL TIMES RAN INTO THE CENTER DIVIDER. I WAS VERY LUCKY NOT TO GO OVER THE DIVIDER INTO ONCOMING TRAFFIC AND BE KILLED. I SUSTAINED NECK AND HEAD INJURIES AND THE CAR WAS TOTALED. I WAS VERY LUCKY THAT I SURVIVED AND THAT NO OTHER CARS OR PEOPLE WERE INVOLVED. EARLY IN 1998 I RECEIVED A RECALL NOTICE AND TOOK THE CAR IN TO LEXUS ON 2/24/98. THE RECALL WAS FOR A "STARTER PLUG PROBLEM". I TRUSTED THAT AFTER THE REPAIR I WOULDN'T HAVE ANY PROBLEMS WITH MY LEXUS. IN FACT, JUST OVER A MONTH LATER I HAD THE ACCIDENT AND THE CAR WAS TOTALED. I VERY HAPPILY DROVE LEXUS CARS FROM 1992 UNTIL THE ACCIDENT AND THEY WERE MY FAVORITE CARS. I HAVE 2 FRIENDS WHO HAD THE SAME MALFUNCTION WITH A 1996 AND A 1997 LEXUS LS 400. I FEEL IT IS MY DUTY TO PROVIDE THIS INFORMATION TO MAKE SURE IT'S INCLUDED IN STUDIES AND HISTORICAL DATA THE NHTSA KEEPS. I HOPE THE INFORMATION WILL BE PUT TO GOOD USE TO PREVENT FUTURE ACCIDENTS, INJURIES AND DEATHS, REGARDLESS OF THE AUTO MANUFACTURER. I BELIEVE THE PROBLEMS TOYOTA IS CURRENTLY EXPERIENCING ARE PROBABLY HAPPENING WITH OTHER AUTO MANUFACTURERS.
NHTSA complaint #10313402 — an unverified report by a vehicle owner.
I'M WRITING THIS IN THE HOPES THAT IT MAY BE OF SOME HELP IN TOYOTAS BRAKE PROBLEM. MY 1999 LEXUS LS400 WOULD LOOSE THROTTLE CONTROL, THE ENGINE SPEED WOULD DROP TO IDLE REGARDLESS OF WHAT WAS DONE TO THE THROTTLE ITSELF. AFTER 3 TRIPS TO THE DEALER, THEY FOUND THAT THE THROTTLE POSITION SENSOR WOULD NOT WORK IF IT HAD BECOME WET. THEY REPLACED THE TPS AND THAT CURED THE PROBLEM.
NHTSA complaint #10310746 — an unverified report by a vehicle owner.
ACCELERATOR PEDAL STICKS AND ENGINE CONTINUES TO ACCELERATE. I CAN ONLY STOP IT BY PUSHING ON THE BRAKE HARD, PUTTING IT IN NEUTRAL OR TURNING OFF ENGINE. SOMETIMES IF I HAVE ROOM IN FRONT OF MY CAR, I CAN STOP IT BY PUMPING THE BRAKE. THIS HAS OCCURRED SEVERAL TIMES. I CANNOT TELL WHAT CAUSES IT. DEFINITELY NOT FLOOR MAT.
NHTSA complaint #10307216 — an unverified report by a vehicle owner.
ACCELERATION STUCK, RPMS LOCK IN AT ABOUT 2000. FAILURE OCCURS ABOUT ONCE OR TWICE DAY, BUT USUALLY ONLY IF THE AIR CONDITION IS TURNED OFF. THIS HAS BEEN GOING ON FOR YEARS NOW WITH MY VEHICLE. I TURN OFF VEHICLE AND RESTART IT TO CORRECT THE PROBLEM AND REGAIN CONTROL OF THE ACCELERATOR, IT ALMOST ALWAYS RETURNS AFTER RESTART. I BELIEVE THIS MAY BE CAUSED BY FAULT IN LEXUS ELECTRONIC THROTTLE SYSTEM AND SINCE YOU ALL ARE FINALLY INVESTIGATING THIS I THOUGHT I SHOULD REPORT IT IN CASE YOU WOULD LIKE TO EXAMINE MY VEHICLE SINCE IT OCCURS SO OFTEN. I WAS TOLD BY LEXUS I SHOULD PURCHASE A NEW THROTTLE BODY, I HAVEN'T DONE SO BECAUSE I DO NOT SEE HOW THAT WILL CORRECT MY ACCELERATOR FROM STICKING IN ONE POSITION DURING DRIVING AND I BELIEVE THIS IS MORE OF A SERIOUS SAFETY ISSUE NOW WITH THE RECALLS FINALLY BEING DONE.
