2001 Toyota Sequoia

VSC/TRAC CONTROL SYSTEM ENGAGED WHILE DRIVING ON SMOOTH DRY ROAD AT 70 MPH. VEHICLE BEGAN TO LURCH AND BRAKE, HAD TO GUIDE TO SIDE OF ROAD. EXTREMELY DANGEROUS. TURNED VEHICLE OFF, RESTARTED, VSC OFF LIGHT AND CHECK ENGINE LIGHT WERE ON. HAS HAPPENED MULTIPLE TIMES SINCE, WITH TOYOTA INDICATING THAT VSC COMPUTER NEEDS TO BE REPLACED FOR $1200+. *TT

WHEN TRAVELING AT ANY SPEED THE TWO WARNING LIGHTS CONCERNING THE TRAC CONTROL ON THE THE DASH COMES ON AND BEEPS SEVERAL TIMES, THE VEHICLE SUDDENLY BRAKES AND PULLS HARD TO THE RIGHT TEMPORARILY LOSING CONTROL. ALL THIS HAPPENS IN A SPLIT SECOND WITH NO WARNING. I AM VERY CONCERNED WITH MY SAFETY ALONG WITH MY FAMILIES AND OTHERS ON THE ROAD CONCERNING THIS SAFETY DEFECT.

WE BOUGHT OUR 2001 TOYOTA SEQUOIA IN JULY 2009. WHILE DRIVING HOME FROM THE USED CAR LOT THE "VSC TRACE" AND THE "VSC OFF" LIGHTS CAME ON AND HAVE NEVER GONE BACK OFF. THE CAR LOT SAID THAT THE VEHICLE WAS "AS IS" AND WE HAD TO DEAL WITH IT. AFTER HAVING THE VEHICLE FOR A MONTH, THE "CRUISE CONTROL" LIGHT STARTED COMING ON, BLINKING AT TIMES, THEN IT WOULD TURN OFF FOR A WEEK OR SO, THEN IT WOULD COME ON STEADY AND BLINK AT TIMES FOR DAYS STRAIGHT. ONE DAY WHILE DRIVING THE "BRAKE" LIGHT, "VSC TRAC" LIGHT, "VSC OFF" LIGHT, THE "DOOR AJAR" LIGHT, AND THE "CRUISE" LIGHT ALL CAME ON AND BLINKED RAPIDLY WHILE DRIVING. AFTER PULLING OVER AND TURNING OFF THE CAR AND BACK ON, THEY WERE STILL BLINKING. I TURNED IT OFF AND ON MANY TIMES AND THEY ALL CONTINUED TO BLINK. AFTER GETTING HOME AND LETTING IT SIT OVER NIGHT, THEY DIDN'T COME BACK ON. CURRENTLY THE "VSC TRAC" AND THE "VSC OFF" LIGHT ARE STILL ON. THE "CRUISE CONTROL LIGHT IS ALSO ON. AFTER TURNING OFF THE VEHICLE AND REMOVING THE KEYS THE "KEY" LIGHT STAYS ON, BLINKING NON-STOP AND THE RUNNING LIGHTS STAY ON. SOMETIMES I CAN RESTART THE CAR AND THE RUNNING LIGHTS WILL STAY OFF AFTER REMOVING THE KEYS AND LOCKING THE DOORS. I COULDN'T GET THEM OFF LAST WEEKEND AND TRIED EVERYTHING, FINALLY THE BATTERY DIED, AFTER I GOT A JUMP START, THEY TURNED OFF. WE CONTINUOUSLY HAVE PROBLEMS WITH THE DASH BOARD INDICATOR LIGHTS AND THE RUNNING LIGHTS STAYING ON TW*

WE WERE DRIVING DOWN THE HILL AND THE TRACTION CONTROL SYSTEM WENT CRAZY WE SKIDDED OUT AND THEN THE ABS AND TRACTION CONTROL/SLIP LIGHTS WENT ON. THEY STAYED ON UNTIL WE TOOK IT TO THE DEALER AND THEY REPLACE SOME BRAKE SENSORS THAT WERE CORRODED. ON THE WAY HOME IT HAPPENED AGAIN. THE TRACTION CONTROL COMPUTER WAS REPORTING THAT THERE WERE STILL BAD SENSORS, BUT THE SENSORS WERE FINE, SO THEY REPLACED THE ENTIRE TRACTION CONTROL COMPUTER. AFTER A WEEK IN THE SHOP IT FINALLY CAME BACK WORKING. A TRACTION CONTROL SYSTEM SHOULD NOT THROW YOUR CAR OUT OF CONTROL AND RUN YOU OFF THE ROAD. THE DEALER SAID THAT THEY HAD NOT SEEN SO MUCH CORROSION UNDER A VEHICLE BEFORE. THEY SAID THAT THE FRAME, EXHAUST, SPARE TIRE, AND BRAKE COMPONENTS AS WELL AS VARIOUS OTHER ELECTRICAL COMPONENTS LOOKED TO HAVE WHAT THEY WOULD CALL EXCESSIVE CORROSION. THEY SAID I SHOULD TAKE IT UP WITH WHOM I BOUGHT IT FROM. I THINK THIS IS THE SAME PROBLEM AS THE TUNDRAS ARE HAVING WITH CORROSION AND SHOULD BE LOOPED INTO THE SAME INVESTIGATION. THE SEQUOIA, I WAS TOLD WHEN I BOUGHT IT, WAS DESIGNED ON THE SAME FRAME, AND DRIVE TRAIN AS THE TUNDRA WHICH WOULD EXPLAIN WHY THE CORROSION IS EFFECTING SIMILAR BRAKING SYSTEMS AND THE SPARE. I WOULD LOVE FOR SOMEONE TO INVESTIGATE THIS. I WOULD HAVE HATED FOR ANYTHING TO HAPPEN TO MY FAMILY WHICH WAS IN THE CAR WITH ME. *TR

WITH NO PRIOR WARNING SYMPTOMS, THE "VSC TRAC" "VSC OFF" BRAKE" AND ABS" LIGHT COME ON IN MY 2001 TOYOTA SEQUOIA. IT STARTED ABOUT 2 WEEKS AGO JUST ONCE IN A WHILE, BUT NOW IT HAPPENS ALMOST EVERY TIME I PUT THE CAR IN MOTION. IT SEEMED TO ME AT FIRST THAT IT HAPPENED MOST FREQUENTLY WHEN THE WEATHER IS COLD (THE HIGH 30S IS ABOUT AS COLD AS IT EVER GETS HERE, THOUGH.) THIS IS A PROBLEM THAT HAS BEEN REPORTED BY MANY OTHERS. SEE HERE: HTTP://WWW.TUNDRASOLUTIONS.COM/FORUMS/1GEN-SEQUOIA/62954-VSC-TRAC-VSC-OFF-BRAKE-ABS-2/. *TR

TL*THE CONTACT OWNS A 2001 TOYOTA SEQUOIA. WHILE DRIVING 65 MPH THERE WAS A LOUD THUMP IN THE RIGHT FRONT PASSENGER SIDE WHEEL AREA, AUTOMATICALLY THE RIGHT FRONT BRAKE WAS APPLIED . THE VSC OFF AND TRACTION LIGHTS ILLUMINATED ON THE INSTRUMENT PANEL. THE CONTACT DEPRESSED THE BRAKE PEDAL AND RELEASED IT, WHICH ALLOWED THE FRONT PASSENGER SIDE BRAKE TO RELEASE AND THE VEHICLE TO DRIVE NORMALLY AGAIN. FOUR DAYS PRIOR TO THE FAILURE, THE CONTACT NOTICED THAT THE VSC OFF AND TRACTION LIGHTS WOULD ILLUMINATE WHILE DRIVING, BUT THEN DIM AFTER THE VEHICLE WAS RESTARTED. THE VEHICLE WAS TAKEN TO THE DEALER AND THEY DISABLED THE VSC SENSOR TO PREVENT THE FAILURE FROM RECURRING. THE CURRENT MILEAGE WAS 47,000 AND FAILURE MILEAGE WAS 44,700. UPDATED 09/10/08. *LJ UPDATED 09/12/08. *JB JUN 10, 2008, WHILE TRAVELING AT APPROXIMATELY 65 MPH THERE WAS A LOUD "THUMP" IN THE RIGHT FRONT PASSENGER SIDE WHEEL AREA, AUTOMATICALLY THE RIGHT FRONT BRAKE WAS APPLIED, THE VEHICLE VEERED TO THE RIGHT, THE VSC OFF AND THE VSC TRACTION LIGHT ILLUMINATED AS WELL AS A MOMENTARY INDICATION OF THE VEHICLE SWERVE INDICATOR CAME ON, I APPLIED THE BRAKES TO REGAIN CONTROL OF THE VEHICLE, SLOWED AND PULLED TO THE SIDE OF THE ROAD TO INVESTIGATE THE PROBLEM. A VISUAL INSPECTION INDICATED NO APPARENT PROBLEM. I STARTED THE VEHICLE AND NOTICED THE VSC. OFF AND THE VSC TRACTION INDICATORS REMAINED ILLUMINATED, THE VEHICLE APPEARED TO HANDLE NORMALLY AT SPEED SO I CONTINUED ON MY TRIP FROM VIRGINIA BEACH, VA. TO DENVER, CO. I COULD NOT TURN THE ILLUMINATED LIGHTS OFF WITH THE MANUAL SWITCH. ONCE I ARRIVED IN DENVER, I TOOK THE VEHICLE TO MOUNTAIN STATES TOYOTA WHERE THE YAW RATE SENSOR WAS UNPLUGGED. THE PROBLEM HAS NOT BEEN REPAIRED AND THE SENSOR REMAINS UNPLUGGED

BRAKE, ABS, SKID CONTROL WARNING LIGHTS ON , DEALER SERVICE CHECKED AND RECOMMENDED REPLACING BATTERY WHICH WAS DONE BY THEM. FOLLOWING DAY WARNING LIGHTS STILL ON INTERMITTENTLY , RETURNED TO DEALER FOR SERVICE BUT THE WARNING LIGHTS WOULD NOT COME ON WHILE THE DEALER HAD IT. WAS ADVISED IT WAS NOT A SAFETY ISSUE, JUST MALFUNCTIONING WARNING LIGHTS. NOW( OCTOBER 2007) THE LIGHTS ARE ALWAYS ON AND WHEN RETURNED TO DEALER FOR SERVICE AGAIN WAS TOLD THIS TIME IT WAS THE SKID CONTROL ECU, AND RECOMMEND REPLACING SKID CONTROL ECU. WAS ALSO TOLD IT THAT THE ABS AND SKID CONTROL WERE NOT FUNCTIONING WHEN LIGHTS WERE ON SO HANDLING WOULD BE AFFECTED (SAFETY ISSUE ). AT THIS TIME I AM GATHERING INFORMATION ON WHETHER IT SHOULD BE REPLACED OR NOT. *TR

I LEASE A USED 2001 TOYOTA SEQUOIA SR5 4WD SUV IN NOVEMBER OF 2001. THE SKID CONTROL ECU HAD FAILED IN 2003 AND A TOYOTA DEALERSHIP DID NOT WANT TO REPLACE IT FOR REASONS THAT THE WARRANTY NO LONGER COVERS IT. TO REPLACE THE ECU COMPUTER, I WILL HAVE TO PAY OVER $2000.00. THIS PROBLEM PREVENTS THE ANTI-SKID CONTROL AND ANTI-LOCK BRAKES (ABS) TO FUNCTION. I HAVE FOUND OUT THAT THIS PROBLEM WITH THE ECU HAS BEEN VERY COMMON FOR THE TOYOTA SEQUOIA'S MADE BETWEEN 2000 AND 2003. THERE ARE SEVERAL OCCASIONS WHERE I ALMOST HAD AN ACCIDENT BECAUSE OF FAILURE OF THE ABS AND ANTI-SKID CONTROL. TOYOTA HAS CLEARLY IGNORED AND AVOIDED TO FIX THIS PROBLEM. I HOPE YOU CAN HELP ME. *JB
