ENGINE
MY 2000 LEXUS RX300 HAD AN UNEXPLAINED SUDDEN UNINTENDED ACCELERATION WHERE THE VEHICLE ALMOST KILLED ME AND MY SON. I WAS DRIVING RESIDENTIAL BACKROADS BY MY HOUSE, ACCELERATED SLIGHTLY TO GET UP A HILL AND THAT'S WHEN IT TOOK OFF. THE BRAKE PEDAL WAS UNRESPONSIVE, THE EMERGENCY BREAK WAS UNRESPONSIVE, I PULLED THE FLOOR MAT OUT FOR GOOD MEASURE, NOTHING WORKED, IT KEPT ACCELERATING AT A HIGH RATE UNTIL I FINALLY SLAMMED IT THROUGH GEARS TO "PARK" TO GET IT TO A STOP. I HAD IT TOWED TO THE LEXUS DEALERSHIP, WHERE THE TOW TRUCK DRIVER EVEN TOLD ME WHEN IT STARTED THE CAR TO GET IT UP ON THE TRUCK, AFTER BEING TURNED OFF FOR OVER 12 HOURS, IT WAS STILL RED LINING THE ENGINE, AND EVEN LURCHED FORWARD BUT BECAUSE THE CAR WAS IN PARK, IT DIDN'T CRASH INTO THE BACK OF THE TOW TRUCK. LEXUS INVESTIGATED THE CAR AND DID ABSOLUTELY NOTHING. THEY WOULDN'T TELL ME WHY IT HAPPENED. I DEMAND AN EXPLANATION AND A REPLACEMENT VEHICLE - ONE THAT DOESN'T HAVE A HISTORY OF HAVING SUA PROBLEMS. I FEAR FOR MY LIFE EVERYTIME I HAVE TO DRIVE THIS VEHICLE.

ENGINE
ON JANUARY 17TH, 2016, I TOOK MY '99 LEXUS RX300 TO CHURCH, PARKED THE CAR, AND JOINED THE SUNDAY SERVICE. AN HOUR AFTER PARKING THE VEHICLE (DURING WHICH TIME IT WAS NOT RUNNING OR IN USE), I WAS TOLD THAT THERE WAS SMOKE COMING FROM IT AND WENT OUTSIDE. WITHIN MINUTES, THE FRONT END WAS BURSTING IN FLAMES. THE FIRE DESTROYED THE ENTIRE FRONT PORTION OF THE CAR, INCLUDING THE ENGINE, TRANSMISSION, TIRES, AND DASHBOARD. I DON'T KNOW WHAT COULD HAVE BEEN THE CAUSE; IT WAS SEEMINGLY RANDOM.

AFTER FIRST HAVING TO REPLACE MY TRANSMISSION AT 75,000 MILES. IT SEEMS I WILL HAVE TO PAY TO DO IT AGAIN AT 186,000. THE PROBLEM STARTED OUT WITH THE VEHICLE HAVING TROUBLE CLIMBING A HILL. I CHANGED THE TRANSMISSION OIL AND TWO WEEKS LATER THE VEHICLE MOVE ABOUT THREE FEET FROM A PARKING STALL MADE A LOUD NOISE JERKED TO A STOP AND WOULD NOT MOVE. I WAS ABLE TO PUT IT INTO DRIVE AND REPARK THE CAR. IT WILL NOT REVERSE AND HAD TO BE TOWED TO A MECHANIC.

ENGINE
MY CHECK ENGINE LIGHT CAME ON. I HAD THE OIL CHANGED FOR THE SECOND TIME WITHIN 30 DAYS BECAUSE I THOUGHT IT WAS AN OIL PROBLEM. THE LIGHT WENT OFF AS I WAS LEAVING THE PLACE. A COUPLE DAYS LATER THE LIGHT WOULD COME ON WHEN I MADE TURNS, BLINK, THEN GO BACK OFF. A FEW DAYS LATER, IT CAME BACK ON STEADY, AND THE CAR STARTED TO JERK WHILE I WAS DRIVING ON THE INTERSTATE. IT WOULD JERK, THEN SLOWLY INCREASE SPEED. LAST SATURDAY, I APPLIED BRAKES, AND THE CAR ROLLED ANOTHER FEW FEET. HAD TO SWERVE LEFT TO KEEP FROM REAR ENDING A VEHICLE. TODAY, UPON SLOWING DOWN TO ENTER MY DRIVEWAY, IT DID IT AGAIN, AND I NEARLY HIT A BRICK COLUMN AT THE BEGINNING OF THE DRIVEWAY. IT DOESN'T JERK FREQUENTLY, BUT IT SEEMS TO DO IT MORE OFTEN WHEN I AM ON CRUISE CONTROL. I LOVE MY SUV AND AM ALWAYS BRAGGING ABOUT WHAT A RELIABLE CAR IT IS. I CAN'T AFFORD TO REPLACE IT, RETIRED AND ON DISABILITY.

ENGINE
I HAVE JUST SAT AND READ PROBABLY 50 COMPLAINTS; SAFETY AND DEFECTIVE, CONCERNING THE TRANSMISSION FOR THE 2001 LEXUS RX300. FROM WHAT IM READING, I GUESS I SHOULD CONSIDER MYSELF LUCKY, I CURRENTLY HAVE 142,000 MILES ON MY VEHICLE AND ALTHOUGH I'VE EXPERIENCED NON-PERIODIC SHIFTING ABNORMALITIES, I HAVEN'T EXPERIENCED ANY OF THE HORRIFIC PROBLEMS I'VE BEEN READING IN THE NHTSA COMPLAINT SECTION OF THIS SITE. IT IS OBVIOUS THERE IS A MANUFACTURING DEFECT THAT NEEDS TO BE ADDRESSED BEFORE SOMEONE (IF NOT ALREADY) IS MANGLED OR WORST, KILLED. IT ASTONISHES ME THAT A COMPANY THAT SURVIVES BY THERE REPUTATION FOR QUALITY WOULD NOT ADDRESS WHAT IS OBVIOUSLY A SERIOUS AND COSTLY BURDEN TO THERE LOYAL CUSTOMERS. WE ARE TALKING ABOUT A 35,000 DOLLAR VEHICLE IN 2001. APPARENTLY LEXUS IS NOT PLANNING ON RESOLVING THE ISSUE, SO WHAT CAN CONSUMERS DO OTHER THAN COMPLAIN WHICH OBVIOUSLY IS DOING NOTHING TO FORCE BIG BUSINESS TO TAKE RESPONSIBILITY FOR THERE POOR DESIGN THAT RESULTED IN UNSAFE COSTLY PRODUCTS, LEAVING THE CONSUMER POWERLESS, WITH NO OPTION BUT TO PAY THEM AGAIN TO FIX THE PROBLEM THEY CREATED IN THE FIRST PLACE.

ENGINE
WHILE ENTERING A FREEWAY ONRAMP THE TRANSMISSION SLIPPED OUT OF GEAR. I TRIED TO ACCELERATE BUT THERE WAS NO POWER THE ENGINE JUST REVVED. THE TRANSMISSION REINGAGED AS I WAS PULLING TO THE SHOULDER SO I CONTINUED MY TRIP HOME. LATER ON THE SAME DRIVE HOME, AT AN INTERCHANGE BETWEEN FREEWAYS IT HAPPENED AGAIN BUT THIS TIME THE TRANSMISSION DIDN'T RE-ENGAGE AND THERE WAS ALMOST A DEADLY MULTIPLE CAR ACCIDENT. IT WAS TOWED TO A TRANSMISSION SPECIALIST WHO HAD TO REPLACE THE TRANSMISSION. SOON AFTER REPLACEMENT I WAS ON ANOTHER TRIP AND I ATTEMPTED TO ACCELERATE TO PASS A CAR, THE TRANSMISSION SLIPPED AND I BARELY AVOIDED BEING IN A DEADLY AUTO ACCIDENT ON THE FREEWAY WITH A BIG RIG. ON THIS SAME TRIP I ALMOST LOST MY LIFE THREE TIMES DUE TO THIS IDENTICAL OCCURRENCE. IT IS ABSOLUTELY UNACCEPTABLE AND UNFORGIVABLE THAT TOYOTA HASN'T TAKEN RESPONSIBILITY FOR THIS MANUFACTURING ERROR AND ANNOUNCED A COMPLETE RECALL AND REPLACEMENT OF ALL TRANSMISSIONS FOR THIS YEAR, MAKE AND MODEL OF VEHICLE. IF, I KEEP THIS CAR AND I HAVE AN ACCIDENT DUE TO THEIR MANUFACTURING NEGLIGENCE ACTION MAY BE TAKEN.

ENGINE AND ENGINE COOLING
THE PAST TWO WEEKS PRIOR TO TAKING THE CAR TO MY LOCAL TOYOTA DEALERSHIP BECAUSE THERE IS NO LEXUS DEALERSHIP IN OCALA , FL ..... I WOULD SMELL SOMETHING BURNING LIKE RUBBER AGAINST A HOT EXHAUST OR ENGINE. EVERY NOW AND THEN I WOULD STOP THE CAR AND CHECK AND I MIGHT SEE A WHIFF OF LIGHT SMOKE BUT THEN NOTHING. NO ENGINE LIGHTS , NO SPOTTING ON THE GARAGE FLOOR. SO I TOOK THE CAR IN FOR AN OIL CHANGE EARLY AND ASKED THAT THEY CHECK THE CAR OVER. 3 HOURS LATER I WAS TAKEN INTO THE GARAGE BAY AND SHOWN OIL DRIPPING FROM THE UNDERSIDE OF THE ENGINE AND TOLD MY SEALS WERE BLOWN AND THE WHOLE ENGINE WOULD NEED TO BE TORN DOWN TO GET TO THEM. WHILE REPAIRING IT TURNED OUT THE WATER PUMP WAS LEAKING BUT THE TIMING BELT CHANGED AT 60,000 MILES WAS OKAY. THE FOLLOWING EVENING I WAS PRESENTED WITH A $1500 BILL MOST FOR LABOR. I GUESS I CONSIDER MYSELF LUCKY THEY FOUND ALL THIS BEFORE I TOOK THIS 12 YEAR OLD CAR ON A LONG TRIP .

ENGINE AND ENGINE COOLING
WHILE PULLING INTO A PARKING SPACE IN MY OFFICE PARKING LOT, I HAD AN UNATTENDED ACCELERATION WHILE MY FOOT WAS ON THE BRAKE. THE CAR LUNGED OVER THE CURB, UP A SLIGHT INCLINE, HIT A SMALL TREE WHICH KNOCKED DOWN THE PERIMETER FENCE. I CALLED THE LEXUS DEALERSHIP AND THEY GAVE ME AN 800 NUMBER TO CALL. I REPORTED WHAT HAPPENED AND THEY SENT A TOW TRUCK TO BRING MY CAR TO THE DEALERSHIP BECAUSE I WAS AFRAID TO DRIVE IT. AT THE DEALERSHIP THEY INDICATED TO ME THAT I WAS NOT SUPPOSE TO BRING IT TO THEM SO I HAD THE MANAGER DRIVE IT TO THEIR COLLISION PLACE WHERE I HAD THE BUMPER REPAIRED. MY INSURANCE COMPANY DID NOT PAY FOR A RENTAL REPLACEMENT. THE REPAIR COST ME $250 (MY DEDUCTIBLE) + THE RENTAL CAR COST OF APPROX. $210.00. MY INSURANCE PAID FOR THE TREE AND FENCE REPAIR OF ABOUT $2,000+. MY CAR WAS SUBSEQUENTLY INSPECTED BY TOYOTA'S INSPECTION COMPANY. IT TOOK ABOUT 3-4 HOURS AND THE END RESULT WAS THAT THE CAR DID NOT HAVE ANY DEFECTS. I CONTINUE TO BE CONCERNED ABOUT WHETHER OR NOT THIS WILL HAPPEN AGAIN AND MAINTAIN A LARGE DISTANCE BETWEEN VEHICLES. IN 2007 MY CAR HAD A SIMILAR PROBLEM WHEN IT ACCELERATED TO A HIGH SPEED BECAUSE THE THROTTLE GOT STUCK DUE TO A MECHANIC'S SERVICE ERROR WHEN WORKED ON THE DAY BEFORE. SINCE TOYOTA SAID MY VEHICLE IS OKAY, I HAD TO PAY THE ALMOST $500 FOR THE REPAIR AND RENTAL CAR AND MY INSURANCE WILL PROBABLY GO UP DUE TO THE PAYMENT MADE TO MY COMPANY FOR THE TREE AND FENCE REPAIR. I THINK THE THROTTLE HAS A FAULTY DESIGN AND I TOLD TOYOTA THAT THIS WAS MY OPINION.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
I PURCHASED A 2001 LEXUS RX 300 FROM A PRIVATE PARTY IN FEBRUARY OF THIS YEAR. WITHIN DAYS OF THE PURCHASE THE TRANSMISSION FAILED AND THAT WAS REPLACED, BUT I HAD ALSO NOTICED SOME BLUE SMOKE WHEN I STARTED IT. I TOOK IT INTO MY AUTO MECHANIC AND HE TOLD ME THAT THE CAR WAS BURNING OIL, AND ACTUALLY THERE WAS A CLASS ACTION SUIT FILED AGAINST TOYOTA RELATED TO THE PROBLEMS, I HAVE BEEN ADVISED THAT THIS CONDITION WILL LEAD TO ENGINE FAILURE IF THE ENGINE IS NOT REPLACED. I HAVE BEEN ADVISED TO FILE A COMPLAINT IN REGARDS TO THIS ISSUE TO SEE IF I QUALIFY TO BE PART OF THE LAWSUIT AND FILE A CLAIM.
