2002 TOYOTA SEQUOIA Electrical System Problems

I was driving my 2002 Toyota Sequoia on the freeway at approximately 65 mph on the [XXX] when suddenly the vehicle made a beeping noise and the VSC Light and TRAC Light came on. The vehicle suddenly lost control in the wheels and tires and suddenly decelerated out-of-nowhere. Due to the sudden, abrupt movement and loss of control, the vehicle nearly flipped over. It was an extremely dangerous, possibly life-threatening situation. Thankfully, I was attentive and alert and had both hands on the wheel and was able to get the vehicle in control. This happened before two times and this would be the third time. I have taken the vehicle to several different auto repair shops and they have been unable to pin point and fix the problem. Because this issue continues to happen and puts me into dangerous situations repeatedly, I firmly believe that this is a bigger malfunctioning/defect...

VSC, ABS, TRACTION CONTROL AND BRAKE WARNING INSTRUMENT LIGHTS ON. ABS AND TRACTION CONTROL AND VSC ARE INOPERABLE DUE TO A COMPUTER MALFUNCTION. 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.

BACK DOOR AND WINDOW DO NOT WORK

TL* THE CONTACT OWNS A 2002 TOYOTA SEQUOIA. WHILE DRIVING VARIOUS SPEEDS, THE BRAKE SYSTEM ENGAGED INDEPENDENTLY. A CRASH DID NOT OCCUR. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER WHERE IT WAS DIAGNOSED THAT THE ELECTRONIC CONTROL UNIT MODULE FAILED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 140,000.

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.

TL* THE CONTACT OWNS A 2002 TOYOTA SEQUOIA. WHILE DRIVING APPROXIMATELY 70 MPH, THE VEHICLE STABILITY CONTROL AND TRACTION CONTROL WARNING INDICATORS ILLUMINATED. IN ADDITION, THE VEHICLE DECELERATED AND BRAKED INDEPENDENTLY. THE VEHICLE WAS NOT TAKEN TO A DEALER AND WAS NOT REPAIRED. THE DEALER AND MANUFACTURER WERE NOT NOTIFIED.

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...

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

I HAVE HAD AN ISSUE WITH MY VSC/TRAC OFF LIGHT SINCE WE BOUGHT IT. THE LIGHT WOULD COME ON AT SEEMINGLY RANDOM TIMES, STAY ON UNTIL I RESTARTED THE TRUCK - WE WERE TOLD IT WAS NOT SOMETHING WE NEEDED TO WORRY ABOUT BY THE DEALERSHIPS IN FORT WORTH (FORT WORTH TOYOTA). RECENTLY (2/2014 & 3/2014), AS I WAS COMING DOWN A HILL IN OUR NEIGHBORHOOD, APPROACHING A STOP SIGN, THERE WAS A GRINDING SOUND AND THE VEHICLE WOULD SEEM TO BE STOPPING INSTEAD OF ACCELERATING - AND THE VSC LIGHTS CAME ON AGAIN. I IMMEDIATELY PULLED OVER AND STOPPED; I COULDN'T SEE ANYTHING WRONG UNDER THE HOOD OR NEAR THE WHEEL WELLS, WHICH IS WHERE IT SOUNDED LIKE IT WAS COMING FROM. IT DID NOT CONTINUE AND DID NOT HAPPEN AGAIN FOR ABOUT A WEEK. THE NEXT TIME IT HAPPENED I WAS ON THE HIGHWAY AT ABOUT 70 MPH....

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...

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

HEADLIGHT RELAY GOES OUT CAUSING HEADLIGHTS TO SHUTOFF WHILE DRIVING. FOR THE 2ND TIME IN A YEAR. PART WAS REPLACED WITH A NEW PART. REAR DOOR WILL NOT LATCH AND RATTLES. REAR LATCH ASSEMBLY WAS REPLACED. IT DOES NOT SHUT OR SEAL SO CARBON MONOXIDE ENTERS THE CABIN. THIS HAS HAPPENED 3 TIMES. BRAKE CALIPERS SEIZE UP FRONT DRIVER AND PASSENGER SIDE, REAR DRIVER SIDE. *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 .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

VSC/TRAC/PARKING BRAKE/ABS LIGHT TURNED ON. DEALER SAID ECU CONTROLLING THESE FUNCTIONS SHUT DOWN. REPLACED ECU FOR $2,000. *TR

BRAKE LIGHT STARTED TO COME ON AND GO OFF WHEN DRIVING, BUT MY MANUAL SAID THIS IS OKAY. THEN THE VSC AND TRAC OFF LIGHTS STARTED TO COME ON AND STAY ON BUT IT DID NOT HAPPEN EVERY TIME I DROVE THE CAR, ONLY HALF THE TIME. *NM

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

WE HAVE A 2002 SEQUOIA, NOT LONG AFTER WE BOUGHT IT THE VSC AND TRAC OFF LIGHT STARTED COMING ON, AND THE BOOSTER ASSY WAS REPLACED BY OUR LOCAL TOYOTA DEALER. WE HAVE HAD TO REPLACE THE BRAKES OR PARTS OF THE BRAKES THREE TIMES, 8/21/02, 3/11/03, AND 5/3/03, COSTING SOME WHERE CLOSE TO $1000.00. ON JUNE 6TH, I TOOK THE SEQUOIA INTO TOYOTA FOR A SERVICE CHECK AND WAS TOLD THAT EVERYTHING WAS FINE. 3 WEEKS LATER WE FELT THAT THERE WAS SOMETHING WRONG WITH THE BRAKES AGAIN, AND CALLED TOYOTA MOTOR CORP. THEY NOTIFIED THE LOCAL DEALERSHIP, AND THE BRAKES WERE REPLACED FOR FREE. NOW TODAY MY VSC AND TRAC OFF LIGHT STARTED COMING ON AGAIN.*AK
