THIS IS AN EXTREMELY COMMON ISSUE WITH FIRST GENERATION SEQUOIAS. MY SPECIFIC CODES ARE C1241 AND C1203. TOYOTA TOLD ME I WILL NEED A NEW COMPUTER TO CONTROLS THOSE SYSTEMS AT A 921 DOLLAR EXPENSE. THESE ISSUES HAVE BEEN ONGOING SINCE 2009.

THE WARNING LIGHTS ABS, VSC, EMERGENCY BRAKES, TRACK, SLIP INDICATOR COMES ON ALL THE TIME AFTER ENGINE START RUNNING. IN CERTAIN INSTANCES, THE VEHICLE DOES NOT RESPOND TO ACCELERATION FOR FEW SECONDS. THE PROBLEM STARTED AROUND 70K MILES. TOYOTA DEALER HAS CHECK THE VEHICLE AND SAID THAT THE PROBLEM IS THE ECU COMPUTER AND THE ESTIMATED COST IS ABOUT $3,000.OO DOLLARS WITH ONLY 3 MONTH WARRANTY. THE MECHANIC EXPLAINED THAT THE VEHICLE WOULD BE ABLE TO BRAKE BUT NON OF THE FEATURES ABOVE WILL BE FUNCTIONING. THE MECHANIC ALSO STATED THAT THIS IS VERY COMMON PROBLEM WITH SEQUOIA MODELS BUT THERE IS NO RECALL OR WARRANTY FOR THIS PROBLEM AT THE TIME IT WAS DIAGNOSED. SINCE THE REPAIR FOR OUR SUV IS NOT AFFORDABLE FOR US AND THERE IS SO MUCH UNCERTAINTY IN ITS SAFETY, WE USE IT IN A LIMITED BASIS.

MY FATHER AND I WERE LEAVING FRYS ELECTRONICS ON FRIDAY MAY 19, 2017. AS WE TURNED FROM THE FRY'S PARKING LOT TO HEAD ON THE 60 FWY ALL OF A SUDDEN THE VSC STARTED BEEPING AND JUST AS WE WE PICKING UP SPEED(50MPH) THE TRUCK STARTED TO SWERVE WHILE AT THE SAME TIME A GRINDING SOUND WENT OFF MY FATHER PUSHED THE VSC OFF SWITCH BUT DID NOT HAVE ANY EFFECT ON WHAT WAS HAPPENING. WHEN THE BEEPING HAD STOPPED BOTH VSC OFF AND VSC LIGHTS HAD STAYED ON AND THE VEHICLE SEEMED TO BE RUNNING OK AND EVER SINCE THAT DAY WHENEVER WE USE THE SEQUOIA THE LIGHTS COME ON AND STAY ON DURING THE TRIP ON OCCASIONS IT DOESN'T TURN ON AFTER ABOUT 5 MINS THE BEEPING GOES ON AND VEHICLE ENGINE IMMEDIATELY SLOWS AND GRINDING SOUND GOES ON AND CAUSES VEHICLE TO SWERVE AND MY FATHER IS A BIT ELDERLY SO AS A SON I AM PUTTING IN THIS COMPLAINT IN HOPES OF SOME ASSISTANCE IN REPAIRS THIS MALFUNCTION. MY PARENTS ARE RETIRED AND DO NOT HAVE AN GOOD INCOME, IS THERE ANY POSSIBLE WAY TOYOTA CAN FIX THIS MALFUNCTION WHICH SEEMS TO BE QUITE A PROBLEM AMOUNGST SEQUOIA OWNERS THANK YOU FOR YOUR TIME AND PATIENCE I WILL AWAIT A RESPONSE THANK YOU. I WOULD ALSO LIKE TO APOLOGIZE TO THE READER FOR THE LACK OF MY LETTER SKILLS AND HOPE I WAS ABLE TO EXPRESS THE PROBLEM FOR YOU TO UNDERSTAND

2002 TOYOTA SEQUOIAL HAS THE VSC AND VSC TRAC LIGHTS ARE ON.WHEN I STARTED MY VEHICLE THEY WERE OFF, THEN THEY JUST STAY ON STEADY.

THE VSC OFF, VSC TRAC, BRAKE LIGHT, AND ABS INDIATOR LIGHTS ON THE DASH BOARD, STAY ON ALL OF THE TIME. I HAVE BEEN TOLD THE VSC LIGHT PROBLEM IS AT LEAST A $700 FIX. THESE LIGHTS HAVE COME ON AND NEVER GO OFF.

THE VSC TRAC & VSC OFF LIGHT BLINKS ON AND OFF CAUSING CAR TO CUT ON AND OFF.WHEN TIS HAPPEN THE CAR WAS IN MOTION. I JUST PURCASED CAR THE DEALER SAID TO REPLACE THE ACCELERATOR PEDAL POSITION SENSOR OF COURSE IT IS NOT COVERED UNDER WARRANTY AND BECAUSE IT HAPPENED RIGHT AFTER 30 DAYS OF PURCHASE IT FALLS ON ME.

VSC TRAC/ VSC OFF, ABS, BRAKE LIGHS COME ON THE VSC TRAC AND THE VSC OFF LIGHT COME ON AND OFF DUE TO A FAULTY ABS SENSOR. TOYOTA DEALER CAN NOT FIGURE OUT WHY OR HOW THIS FAULTY LIGHT COMES ON. DID A RESEARCH ONLINE AND HUNDREDS OF THOUSAND OF OTHER TOYOTA SEQUOIA OWNER HAD THE SAME ISSUES.

TL* THE CONTACT OWNS A 2002 TOYOTA SEQUOIA. WHILE DRIVING 35 MPH AND MAKING A RIGHT TURN, AN ABNORMAL NOISE EMITTED FROM THE CONSOLE OF THE VEHICLE. THE VEHICLE WAS TAKEN TO A DEALER, WHO DIAGNOSED THAT THE COMPUTER NEEDED TO BE RECALIBRATED. THE VEHICLE WAS REPAIRED; HOWEVER, THE FAILURE RECURRED ON NUMEROUS OCCASIONS. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 240,000.

AS I WAS DRIVING MY VEHICLE IT MADE A GRINDING SOUND ALONG WITH A BRIEF SLOWDOWN AND THEN THE VSC TRACK LIGHT CAME ON. WHEN YOU TURN THE VEHICLE OFF THE LIGHTS GO OFF AND STAY OFF UNTIL ANOTHER EPISODE. THIS HAS HAPPENED ON THREE DIFFERENT OCCASIONS. *TR

WHILE DRIVING THE VEHICLE VSC TRAC BUTTON LIGHTS UP, VEHICLE STARTS BEEPING, THE TIRES SHAKE PULLING VEHICLE WHEEL LEFT TO RIGHT WHILE A V GRINDING SOUND COMES FROM UNDER THE VEHICLE. IT STARTED DOING V THIS FOR ONLY A FEW SECONDS THEN STOPS. THE FIRST INCIDENT HAPPENED IN MAY 2014, THEN NOTHING C AGAIN UNTIL JULY 2014. NOW IT HAPPENS SEVERAL TIMES RANDOMLY THROUGH THE DAY FOR UP TO 15 SECOND STRETCHES AT VARYING SPEEDS. *TR

VSC TRAC, TRAC OFF, BRAKE, AND ABS LIGHTS ON AS THE SAME TIME FOR THE LAST COUPLE MONTHS. SOMETIMES THE CAR STRADDLED A LITTLE BIT WHEN I DROVE ON FREEWAY. I CHECKED THE CODE, BUT THERE ARE NO CODE. I TRIED TO LOOKING FOR HELP ONLINE, BUT I AM SURPRISED, THERE WERE A LOT OF TOYOTA SEQUOIA OWNER HAS THE SAME PROBLEM LIKE MINE. *TR

I TRIED TO SOUND THE HORN TO ALERT OTHER DRIVER OF MY PRESENCE AND THE HORN DID NOT SOUND. I HAD IT CHECKED AND IT WAS FOUND THAT THE SWITCH WHICH IS BUILT IN WITH THE DRIVER AIRBAG IS DEFECTIVE. THIS IS A SAFETY ISSUE AS I HAVE READ ONLINE THAT OTHER SEQUOIA OWNERS ARE HAVING THE SAME PROBLEM. *TR

THE VSC LIGHTS AND TRACTION LIGHTS HAVE BEEN RANDOMLY COMING ON SINCE WE PURCHASED THE SEQUOIA IN 2005 WITH APPROX. 80K ON IT. THEY TYPICALLY GO OFF ON THEIR OWN AND DO NOT CAUSE ANY ISSUES. NOW THE SLIP INDICATOR LIGHT COMES ON, FLASHES AND BEEPS WHILE LOCKING UP THE ABS AND MAKING IT IMPOSSIBLE TO MOVE UNTIL IT COMES TO A COMPLETE STOP. WE HAVE BEEN FORTUNATE THAT THIS HAS ONLY HAPPENED AT LOW SPEEDS AND NOT CAUSED ANY ACCIDENTS YET. IT APPERARS THAT THIS IS A WIDE SPREAD ISSUE WITH A COMBINATION OF PARTS STARTING WITH THE VSC COMPUTER, YAW SENSOR AND STEERING ANGLE SENSOR. HOPEFULLY TOYOTA WILL TAKE CARE OF THIS DUE TO THE OVERALL SAFETY CONCERN. *TR

DRIVING AT 75MPH AND INEXPLICABLY LOST VEHICLE SPEED. ENGINE WAS RUNNING BUT WOULD NOT RESPOND TO FOOT FEED, I.E. PRESS DOWN ON ACCELERATOR AND LITTLE TO NO INCREASE IN RPMS FROM IDLE. DEALER REPLACED THROTTLE POSITION SENSOR. *TR

WHILE DRIVING THE VEHICLE, AN ALARM STARTED GOING OFF AND SKID CONTROL LIGHT ON DASH WAS FLASHING AND THEN MOTOR LOST RPM, THE VEHICLE SHOOK AS IF ALL THE TIRE WHERE FLAT, THIS HAPPENED FOR ABOUT 30 SECONDS, WHILE I TRIED TO GET OUT OF TRAFFIC AND OFF THE ROAD, THEN THE VSC LIGHTS CAME ON IN THE DASH, THEN THE VEHICLE SMOOTHED OUT AND RAN NORMAL! AFTER LOOKING AT ALL THE FORUM ONLINE FOR THIS PROBLEM, IT APPARENTLY IS A HUGE PROBLEM WITH THESE VEHICLES AND AFTER CALLING TOYOTA ABOUT THIS THEY CLAIM THAT THIS PROBLEM DOES NOT EXIST, AS ALL THE FORUM WE READ SAID THAT TOYOTA WOULD NOT EXCEPT RESPONSIBILITY FOR THIS SAFETY PROBLEM! THEREFOR WE FILED A CASE TO TOYOTA, HOPING THEY COULD HELP US OUT! BECAUSE THIS HAPPENS ON THE ROAD IT IS HARD TO HAVE IT IDENTIFIED BY A MECHANIC AND A COMPUTER! WE CANNOT WITH THIS ECONOMY IN ANYWAY AFFORD THE EXTREME HIGH PRICE OF TOYOTAS SERVICE WORK , I FEEL MY FAMILY COULD BE IN GREAT DANGER! *TR

WHILE ON THE HIGHWAY, SUDDENLY THERE WAS A LOUD GRINDING NOISE IN THE FRONT END OF THE CAR, THE CAR LOST ALL POWER, AND THE VSC ALARM WENT OFF AND THE VSC DASHBOASD LIGHTS WERE FLASHING. THIS LASTED FOR ABOUT 30 SECONDS AND THEN STOPPED. THIS HAS HAPPENED AGAIN AND AGAIN AT ALL DIFFERENT SPEEDS AND NOW THE VSC LIGHTS ARE ON ALL THE TIME AND THE GRINDING HAPPENS INTERMITTENLY. *TR

ANTI-LOCK BRAKING SYSTEM ENGAGES SUDDENLY WITH POWER LOSS AND FRONT END VIBRATION. VEHICLE STABILITY CONTROL AND TRACTION CONTROL LIGHTS ILLUMINATE ON DASH. ABS AND VSC LIGHTS REMAIN ON (ABS AND STABILITY CONTROL THEREFORE DISENGAGED) AND CANNOT BE TURNED BACK ON BY OPERATOR. WHEN VEHICLE IS TURNED OFF, SYSTEM APPEARS TO RESET, BUT THE PROBLEM REPEATS AFTER RESTARTING AND DRIVING SEVERAL MILES. PROBLEM OCCURRED TWICE TODAY, ON TWO SEPARATE DRIVE EVENTS WITHIN A 2 HOUR PERIOD. *TR

TL* THE CONTACT OWNS A 2002 TOYOTA SEQUOIA. THE CONTACT STATED THE VSC, VSC-OFF, EMERGENCY BRAKE, AND CHECK ENGINE WARNING LIGHTS WOULD INTERMITTENTLY ILLUMINATE ON THE DASHBOARD. IN ADDITION, THE VEHICLE WOULD ABNORMALLY ACCELERATE SPORADICALLY WHEN SITTING IDLE AT A STOP. THE VEHICLE WAS NOT TAKEN TO THE DEALER FOR FURTHER ANALYSIS. THE FAILURE MILEAGE WAS 113,000 AND THE CURRENT MILEAGE WAS 116,000.

THE CHECK ENGINE LIGHT, TRACK, VSC, ABS LIGHT ARE ALL ON. THE DEALERSHIP FOUND A CODE OF C1241 WHICH WAS THE SKID CONTROL ECU HAD SHORTED INTERNALLY AND IT WAS NECESSARY TO REPLACE SKID CONTROL ECU AND RECALIBRATE ALSO BLEED BRAKE SYSTEM. AS YOU KNOW THE VEHICLE SKID CONTROL SYSTEM HELPS PROVIDE INTEGRATED CONTROL OF THE SYSTEMS SUCH AS ANTI-LOCK BRAKE SYSTEM, TRACTION CONTROL, ENGINE CONTROL, ETC. THIS SYSTEM AUTOMATICALLY CONTROLS THE BRAKES AND ENGINE TO HELP PREVENT THE VEHICLE FROM SKIDDING WHEN CORNERING ON A SLIPPERY ROAD OR SURFACE OR OPERATING STEERING WHEEL ABRUPTLY. I AM LOOKING FOR SOME ASSISTANCE AS THE CHARGE FROM THE DEALER WAS QUOTED AT $2714.12. THIS ISSUE SEEMS LIKE A RECALL FEATURE. *TR

2002 TOYOTA SEQUOIA ELECTRICAL ISSUES-AIR CONDITIONING COMES ON SPONTANEOUSLY WITHOUT INITIATION BY DRIVER, BACK WINDOW ALWAYS FAILING TO OPERATE PROPERLY, NOT OPENING OR CLOSING @ TIMES, NOW STUCK CLOSED, TRACKING DEVICE COMES ON FOR LONG PERIODS WITH USED & NEW TIRES, EVEN AFTER NUMEROUS PROFESSIONAL ALIGNMENTS, AND PROPER DRIVING, ENGINE LIGHT ALWAYS ON. ALL OF THESE ISSUES HAVE BEEN BOUGHT TO THE ATTENTION OF TOYOTA SERVICE DEPT , THE SUV HAS BEEN INSPECTED BY TOYOTA ON NUMEROUS OCCASIONS, AND PARTS HAVE REPORTEDLY BEEN REPLACED, HOWEVER, THESE ISSUES CONTINUE, THERE ARE ALSO NO DEVICES IN PLACE TO KEEP THE DRIVER'S MAT FROM CURLING OVER THE ACCELERATOR AND BRAKE PEDALS. *TR

TL*THE CONTACT OWNS A 2002 TOYOTA SEQUOIA. WHENEVER THE CONTACT DRIVES THE VEHICLE HE NOTICED THAT THE SKID CONTROL WARNING LIGHT WOULD APPEAR ON THE DASHBOARD, MOMENTS LATER THE ANTI-LOCK BRAKING SYSTEM WOULD ACTIVATE CAUSING THE VEHICLE TO DE-ACCELERATE ON ITS OWN. THE CONTACT ALSO NOTICED THAT THE FAILURE WOULD NOT LAST MORE THAN 15 SECONDS BEFORE CORRECTING ITSELF. THE VEHICLE HAS BEEN DIAGNOSED BY THE DEALER. THE CONTACT PREVIOUSLY NOTICED THAT THE VCS LIGHT WOULD APPEAR ON THE DASHBOARD. THE CURRENT AND FAILURE MILEAGES WERE 127,000. UPDATED 01/05/10 *BF THE DEALER DETERMINED AN AFTERMARKET WIRING HARNESS FOR THE T.V, DVD AND VCR WAS INCORRECTLY ROUTED THROUGH THE STEERING COLUMN AND ATTACHED TO THE VSC AND STEERING POSITION SYSTEM SENSOR WHICH CAUSED THE FAILURE. THE WIRING WAS RE-ROUTED AND THE PROBLEM WAS SOLVED. THE ORIGINAL DEALER INSTALLED THE WIRING HARNESS INCORRECTLY IN 2002. UPDATED 01/06/10*JB

TL* THE CONTACT OWNS A 2002 TOYOTA SEQUOIA .WHEN DRIVING THE VSC LIGHT, ABS LIGHT, AND TRACTION CONTROL LIGHT WERE ILLUMINATED ON THE INSTRUMENT CONTROL PANEL. THE VEHICLE HAS NOT BEEN TAKEN TO THE DEALER FOR INSPECTION. THE FAILURE AND CURRENT MILEAGES WERE 52000.

2002 TOYOTA SEQUOIA ECU FAILS TO RESET AFTER ABS, VCU, SKID CONTROL & CHECK ENGINE LIGHTS ARE ON. TOLD BY DEALER THAT I NEED TO REPLACE THE ECU (OVER $2300.00) AND THAT CHANGING IT MAY NOT SOLVE THE ABS LIGHT PROBLEM. I MAY HAVE TO THEN REPLACE THE BRAKE BOOSTER FOR AN ADD'L $ 1200.00. THAT'S ABSOLUTELY RIDICULOUS TO HAVE TO REPLACE A $2300.00 PART AND STILL NOT RECTIFY THE PROBLEM. ALL THIS TELLS ME IS THAT THEY REALLY DON'T KNOW WHAT THE PROBLEM AND MAKE EXPENSIVE REPAIR SOLUTIONS. *TR

AUTOMOBILE STOPS OPERATING WITHOUT NOTICE OR WARNING. WILL NOT START AGAIN. *NM

I OWN A 2002 TOYOTA PRIUS. IT HAS BEEN AT TOYOTA OF ST. THOMAS FOR OVER 6 MONTHS UNDERGOING "REPAIRS". I DON'T KNOW WHEN I WILL EVER GET IT BACK AS THEY SEEM UNABLE TO REPAIR IT. *NM

I HAVE A 2002 TOYOTA SEQUOIA SR5 2 WHEEL DRIVE - THE VSC AND TRAC OFF LIGHTS COME ON AND OFF RANDOMLY. I HAVE TAKEN IT IN SEVERAL TIMES AND COMPLAINED OF THIS ISSUE. THE FIRST TIME (WITH ABOUT 15000 MILES) I WAS TOLD FRONT BRAKES NEEDED REPLACED - WHICH I DID. PROBLEM RETURNED AND WHEN I TAKE IT IN, DEALER SAYS THEY CAN'T DUPLICATE THE PROBLEM, SO THERE IS NOTHING THEY CAN DO. THERE IS SOMETHING WRONG, THEY ARE IGNORING IT. *LA
