2001 Toyota Sequoia

INTERMITTENT VSC CONTROL WARNINGS, BREAKING ENGAGED WITH PULLING VEHICLE STEERING TO THE RIGHT. SOMETIMES WITH ONLY THE WARNING LIGHTS AND CHECK LIGHTS. FIRST OCCURRENCE DAY AFTER PURCHASE OF THIS USED VEHICLE (50 MILES). TOOK BACK TO DEALERSHIP AND COULD NOT FIND NOTHING WRONG, VERY SCARE . SPEED HAS BEEN BETWEEN 10 TO 65 MPH. HIGHWAY AND CITY DRIVING.

MY 2001 SEQUOIA (151,000 MI) WHICH HAS BEEN GARAGED AND MAINTAINED METICULOUSLY IS SUDDENLY SHOWING THE VSC LIGHTS AND BRAKE LIGHTS AT THE SAME TIME! THERE IS A VERY ROUGH FEELING WHEN I'M DRIVING THE CAR LIKE SOMETHING IN THE UNDERCARRIAGE IS VERY WRONG. THERE IS A "CLUNKING" NOISE AS SLOW AS 5 MPH AT ALL TIMES AND ALL SPEEDS. AT HIGH SPEEDS, THE CAR WILL SUDDENLY PULL TO THE LEFT MOMENTARILY AND THEN RELEASE ITSELF BUT THE LIGHTS NEVER GO OUT UNLESS CAR IS OFF. I HAVE READ THE 138 COMPLAINTS AT THE DOT.GOV SITE ABOUT THIS EXACT PROBLEM AND THUS FAR, TOYOTA CORP IS IGNORING THE COMPLAINTS.WHERE IS THE RECALL FOR THIS PROBLEM. I KNOW ALOT OF OWNERS WHO HAVEN'T EVEN INVESTIGATED WHY IT'S HAPPENING IN THIER TRUCK TOO. HOW CAN THEY DO BUSINESS LIKE THIS ??? THIS IS A LIFE THREATENING PROBLEM FOR TOYOTA !!! I WILL STOP AT NOTHING TO HAVE TOYOTA REPAIR THEIR PROBLEM ON THEIR PRODUCT. JUST FIX YOUR PROBLEM TOYOTA AND I WILL CALL OFF THE DOGS... SIMPLE STUFF.

I AM HEARING A RATTLING SOUND THAT SOUNDS AS IF IT IS COMING FROM THE TRANSFER CASE. I HAD RECENTLY (10 DAYS) REPLACED ALL THE SHOCKS WITH BILSTEIN AND REPLACED THE TIRES WITH PIRELLI ATR P265/76R-16. THE PROBLEM APPEARS MORE PRONOUNCED IN A TURN AND OVER MORE ROUGH ROAD (NOTHING CRAZY, ASPHALT HIGHWAY). I DO NOT NOTICE THE SOUND AT HIGHWAY SPEEDS. I SUSPECT THAT THIS CONDITION MAY BE ASSOCIATED WITH THE ATC OR VSC SYSTEM. I TRIED TO DISCONNECT THE VSC SYSTEM HOWEVER I STILL WOULD OCCASIONALLY GET THE NOISE. THIS IS SIMILAR TO A PROBLEM I HAD 6 YEARS AGO: WHILE IN MOTION, ENTERING A DOWNHILL TURN, THE VEHICLE BEGAN TO SHAKE UNCONTROLLABLY. MY FIRST THOUGHT WAS THAT THE ENTIRE WHEEL ASSEMBLY WAS SHEARING OFF. THE CONDITION WAS MORE COMMON IN A TURN, BUT COULD BE INDUCED IN A BUMP. I HAD RECENTLY INSTALLED NEW TIRES AND A SUSPENSION SO THE DEALERSHIP SUGGESTED THAT THE SLIGHTLY OVERSIZED TIRE (P265/75R-16) WAS HE CAUSE. I REPLACED THE BRAND NEW PIRELLI TIRES WITH THE FACTORY SIZE MICHELLIN'S HOWEVER THE PROBLEM CONTINUED. I HAD THE VEHICLE RE-INSPECTED AND THE TECHNICIANS STATED THAT THE PROBLEM WAS A WORN RACK & PINION ASSEMBLY. I PAID TO HAVE A NEW ASSEMBLY INSTALLED; THOUGH THE VEHICLE WAS SUPPOSED TO HAVE BEEN TEST DRIVEN IT EXHIBITED THE SAME SYMPTOMS WHEN I DROVE IT. AFTER RETURNING TO THE DEALER I HAD THE HEAD MECHANIC TEST DRIVE WITH ME; HE STATED THAT THIS WAS A NORMAL VSC OPERATING CONDITION. I INSISTED TO SPEAK WITH SOMEONE HIGHER UP AND HAPPENED TO CONNECT WITH A TOYOTA FACTORY ENGINEER FROM JAPAN. AFTER A TEST DRIVE HE CONCLUDED THE PROBLEM WAS PROBABLY SOMETHING IN THE VSC SYSTEM. AFTER FURTHER INSPECTION THEY DISCOVERED A SENSOR WAS BAD. I HAD TO PAY FOR THIS REPAIR AS WELL. NOW, I AM BEGINNING TO HAVE THE SAME PROBLEMS, COINCIDENTALLY, AFTER A TIRE REPLACEMENT USING A PIRELLI P265-75R-16 AND NEW BILSTEIN SHOCKS.

WHILE DRIVING DOWN THE ROAD ABOUT 30-45 MPH THE VEHICLE SUDDENLY JERKED TO THE LEFT AS IF SOMEONE ELSE TURNED THE STEERING WHEEL. IF I HADN'T MOVED FAST IT WOULD HAVE BEEN A MAJOR ACCIDENT IN THE NEIGHBORING LANE. THERE WAS A BEEP AT THE SAME TIME AND THE TRAC LIGHT AND VSC TRAC LIGHT WENT ON. UPON FURTHER TESTING THE YAW RATE SENSOR HAD A FAIL CODE OF C1234 AND THE CODE C1363 BOOSTER PEDAL FORCE SWITCH VAULT WAS ALSO AFFECTED. OUR YAW RATE SENSOR NEEDED REPLACING. I HEAR A RECALL IS IN THE WORKS FOR THIS. IF AO I WANT A REFUND PLEASE. IT WAS VERY SCARY AND DANGEROUS.

REGARDLESS OF SPEED A WARNING BELL WILL SOUND, SEVERAL INSTRUMENT LIGHTS COME ON AND THE BRAKES ACTIVATE CAUSING THE VEHICLE TO PULL TO THE RIGHT. I'VE EXPERIENCED THIS NUMEROUS TIMES WITH SEEMINGLY NO COMMON DENOMINATOR. NEITHER SPEED NOR STEERING INPUT SEEM TO BE THE TRIGGER FOR THIS. I'VE TAKEN IT TO MY LOCAL TOYOTA DEALERSHIP WITH NO SATISFACTION AND CONTACTED TOYOTA OF AMERICA CUSTOMER SERVICE WITH NO SATISFACTION.

AUDIBLE SOUND GOES OFF; TRUCK ABS BRAKES AND PULLES TO THE RIGHT; VSC LIGHT COMES ON AND TRACTION LIGHT COMES ON AND STAYS ON; GRINDING NOISES COMES FROM FRONT AND MIDDLED OF TRUCK. THIS OCCURED WHILE RIDING HWY I-95S AT 80MPH ON SUNNY DRY DAY. THIS HAS TO HAPPEN MUTIBLE TIMES OVER LAST 5YRS; MILEAGE WHEN IT STARTED WAS 128,000 AND PRESENT HAVE 159,000.

TUESDAY, NOVEMBER 10, 2015, I WAS DRIVING DOWN INTERSTATE 37 TOWARD CORPUS CHRISTI, TX, AND OUT OF THE BLUE MY WELL MAINTAINED VEHICLE HAD A HARD SHAKE/SHIMMY IN THE REAR END. IT ROCKED MY REAREND LEFT TO RIGHT. VERY SCARY. LUCKILY I HAD BOTH HANDS ON THE WHEEL. THE TRACTION CONTROL SENSOR WENT OFF. I BRAKED, THINKING MAYBE I HAD HAD A TIRE GO FLAT QUICKLY. VERY SCARY AT 75 MPH. ALSO VERY LUCKY THAT NOT SEMI'S OR VEHICLES WERE NEAR ME. I TURNED THE SEQUOIA OFF AND GOT OUT TO CHECK THE TIRES. THERE WAS NO PROBLEM. I GOT BACK IN AND RESTARTED THE VEHICLE, THE TRACTION CONTROL LIGHTS HAD GONE OFF, SO I STARTED TO ACCELERATE BACK INTO TRAFFIC...AND THE SEQUOIA WENT CRAZY AGAIN, REAR END SHAKING, TRACTION CONTROL LIGHTS GOING OFF. IT WAS 8 PM, DARK. I WAS TOO SCARED TO TRY DRIVING AGAIN, SO I CALLED FOR A TOW. I HAVE DONE SOME RESEARCH ON SIMILAR PROBLEMS AND FOUND THERE WERE MANY. SOME PEOPLE SAY IT IS AN ELECTRONIC CONTROL SENSOR. EACH WHEEL HAS ONE AND MAYBE ONE WENT OUT CAUSING THAT WHEEL TO ROTATE DIFFERENTLY FROM THE OTHERS, JERKING THE CAR AROUND. THIS IS VERY DANGEROUS! I HAD BEEN IN SAN ANTONIO, TX RUSH HOUR TRAFFIC JUST 3 HOURS BEFORE AND HAD THIS JERKING THAT CAUSED SWERVING HAPPENED ON THE DOWNTOWN HIGHWAYS, SOMEONE COULD HAVE BEEN KILLED. PEOPLE SHOULD BE WARNED AND TOYOTA SHOULD RECALL VEHICLES AFFECTED, BECAUSE FROM MY RESEARCH, THERE ARE A LOT OF AFFECTED SEQUOIAS.
