2005 TOYOTA SEQUOIA Vehicle Speed Control Problems

After several years of fighting problems with, after braking to a brief stop, the loss of power/abs grinding when accelerating and turning right, now the ABS is completely dysfunctional. Both TRC lights will turn on and usually the parking brake, and when braking at speeds less than 10mph the abs will activate and prevent bring the truck to a stop without pumping them, on dry pavement. When the ABS light turns on, then braking is possible, but all pressure is gone from brake booster and brakes sound like they're grinding, not like the sound of abs engaging. Very dangerous to drive in snow as front brakes work but drive axle doesn't disengage when the brake pedal is depressed. Regular mechanic won't engage with diagnosing issues as he feels the problem is partly computer malfunction and Toyota won't allow for used part mismatching. ABS/ECU is failed.

Malfunction indicator lights - Check engine, VSC off and TRAC off. The vehicle goes into limp mode. The issue is both a mechanical and engineering defect causing the override of the entire AIP system. Parts affected are Air injection pumps, Air switching valves, Air pump inlets/covers, Gaskets/connectors/clamps and Speed sensors.

I GET CONSTANT WARNING LIGHTS FOR BRAKE, VSC AND TRAC. THIS IS A VERY COMMON PROBLEM WITH THE SEQUOIA. IT SHUTS DOWN THOSE SAFETY FEATURES.

TL* THE CONTACT OWNS A 2005 TOYOTA SEQUOIA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE INDEPENDENTLY ACCELERATED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO AN UNKNOWN DEALER WHERE IT WAS DIAGNOSED, BUT THE CAUSE OF THE FAILURE WAS UNDETERMINED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE, BUT DID NOT OFFER ANY ASSISTANCE. THE VIN AND FAILURE MILEAGE WERE UNKNOWN.

MY VEHICLE WILL SUDDENLY ACCELERATE FOR NO REASON. THIS SUDDEN "UNINTENDED ACCELERATION OF POWER" COMES ON WITH NO NOTICE. I HAVE ALMOST HIT A PERSON AND HAVE BEEN IN ONE CAR ACCIDENT AS A RESULT. THIS UNINTENDED ACCELERATION PROBLEM HAS OCCURRED ABOUT 10 TO 12 TIMES. THE UNINTENDED ACCELERATION HAS OCCURRED BOTH IN STATIONARY & IN MOTION; AND BOTH ON A CITY STREET AND HIGHWAY. TURNING HAS NOT BEEN AFFECTED BY UNINTENDED ACCELERATION. TOYOTA HAS TESTED AND PROVIDED THE ATTACHED REPORT TO ME BUT WITHOUT ANY INTERPRETATION. MY VEHICLE REPAIR COST BECAUSE OF THE UNINTENDED ACCELERATION WAS $4,529.24. TOYOTA STILL HAS NOT RESPONDED TO THIS DANGEROUS AND LIFE THREATENING SITUATION. THE MANUFACTURER COULD NOT DUPLICATE THE FAILURE. UPDATED 10/04/2017*JS

I EXPERIENCED A PROBLEM WITH ENGINE WARNING AND VSC TRAC OFF LIGHTS GOING ON. THE CHECK ENGINE LIGHT ALSO CAME ON. MY FAMILY AND I WERE ON A TRIP AND OUR SEQUOIA ALL OF A SUDDEN LOST POWER. IT SLOWED DOWN DRAMATICALLY EVEN THOUGH THE ENGINE WAS FINE. IT WAS A VERY DANGEROUS SITUATION BECAUSE WE WERE ON AN INTERSTATE WHERE THE SPEED IS 70 MPH. I ALSO EXPERIENCED ALL THE BRAKES MAKING A MASSIVE GRINDING NOISE WHILE GOING SLOW INTO A RESTAURANT. (THE BRAKES HAVE LESS THAN 3000 MILES ON THEM.) THE PARKING BRAKE LIGHT ALSO COMES ON PERIODICALLY.

I HAVE VSC TRAC, VSC OFF, AND CHECK ENGINE. IF YOU GIVE IT A LOT OF FUEL, IT JUST SOUNDS LIKE IT WANTS TO GO, BUT IT DOESN'T TRANSLATE INTO POWER IN THE REAR END. I USE MY CODE READER AND IT SHOWED CODES P1441 AND P1444. SAYS I MAY HAVE: A) FAULTY VACUUM SWITCHING VALVE (VSV) FOR AIR INJECTION CONTROL CIRCUIT, B)FAULTY AIR SWITCHING VALVE NUMBER 2, OR C)FAULTY VSV FOR AIR INJECTION SYSTEM. THIS IS THE SECOND TIME THIS HAPPENED TO MY SEQUOIA, AND THIS SEEMS TO BE A RECURRING ISSUES FOR TOYOTA SEQUOIA OWNERS AND IN FACT IT IS A RECURRING ISSUES FOR OTHER MODELS AS WELL. THIS COST ME APPROXIMATELY $2200 LAST TIME AND NOW 2 YEARS LATER IT IS BACK FOR ANOTHER $2200 TO REPAIR. IT'S ALL THE OVER THE INTERNET ABOUT THIS VSC TRAC, VSC OFF, AND CHECK ENGINE, IT NEEDS TO BE RECALLED!

OYOTA SEQUOIA 2005 ENGINE LIGHT ON ,VSC OFF LIGHT AND TRAC VSC LIGHT ON. THESE COMPLAINTS ARE ABOUT THIS PROBLEMS HTTP://WWW.AUTOMOTIVEFORUMS.COM/T544406-SEQUOIA_VSC_TRAC_PROBLEM.HTML,HTTP://WWW.CARCOMPLAINTS.COM/TOYOTA/SEQUOIA/2003/ELECTRICAL/VSC_TRAC_LIGHTS_ARE_ON.SHTML,HERE ARE TONS OF OTHER COMPLAINTS ON THIS PROBLEM AND IT IS NOT LIMITED TO OUR YEAR MODEL. IF ALL OF THE COMPLAINTS WERE COMPILED IN ONE AREA AND PRESENTED TO THE NTSB, I'M SURE THAT TOYOTA WOULD BE FORCED TO DEAL WITH THIS ISSUE AND CORRECT IT. ITS A BIG ISSUE ESTIMATED COST FOR THAT AROUND $ 2000 TO $ 5000 I DON`T KNOW IF U INVESTIGATE OR NO .I AM NOT GOING TO GET THIS ISSUE REPAIR UNTIL I WILL HEAR FROM YOU .PLEASE TAKE IT SERIOUSLY

WHEN TURNING CORNERS IN MOTION, THE TRACTION CONTROL LIGHT ILLUMINATES CAUSING A LOSS OF BRAKING AND ACCELERATION. THERE IS NOW WAY TO CONTROL THE VEHICLES ACCELERATION/DECELERATION UNTIL THE LIGHT GOES OFF. TYPICALLY LAST ABOUT 3-5 SECONDS. THIS HAPPENS FREQUENTLY EVERY TIME THE VEHICLE IS DRIVEN.

WAS DRIVING AND VEHICLE SLOWED DOWN TO ABOUT 35 40 MPH AND WOULD NOT ACCELERATE PASS 40. WAS IN MOTION ON A CITY STREET

WHILE DRIVING AT 35 MPH, THE CHECK ENGINE LIGHT, VSC OFF LIGHT, VSC TRAC LIGHT, AND THE EMERGENCY BRAKE LIGHT ALL CAME ON AT ONCE, AND THE VEHICLE STOPPED ACCELERATING, AND I EXPERIENCED A DRAMATIC DECREASE IN VEHICLE POWER. I DROVE THE VEHICLE HOME NOTICING A DRASTIC CHANGE IN ACCELERATION AS THE SEQUOIA WOULD NOT ACCELERATE NORMALLY; IT WOULD ACCELERATE AT A SIGNIFICANTLY REDUCED RATE, TOPPING OUT AT 35MPH ON THE FLATS, 30 MPH ON AN INCLINE, I WAS ABLE TO REACH 70MPH GOING DOWN HILL ON A HIGHWAY. SINCE THAT DAY, DURING START UP, THE ENGINE MAKES A HIGH-PITCH VACUUM NOISE, WHICH DROPS OFF AND NORMAL ENGINE SOUND RETURNS. ALL DASHBOARD LIGHTS ARE NORMAL, UNTIL 10-15 SECONDS AFTER START, WHEN THE VSC OFF/VSC TRAC/BRAKE LIGHTS ALL ILLUMINATE, AND REMAIN ON UNTIL THE ENGINE IS TURNED OFF AND THE POOR ACCELERATION AND DECREASE POWER ARE NOW THE NORM. THIS IS...

TL* THE CONTACT OWNS A 2005 TOYOTA SEQUOIA. THE CONTACT STATED THAT THE BRAKE WARNING LIGHT ILLUMINATED. IN ADDITION, THE VSC TRACK OFF AND THE CHECK ENGINE WARNING LIGHTS ILLUMINATED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 103,000.

WITHIN THE FIRST TWO WEEKS, AFTER PURCHASING THE VEHICLE, THE "BRAKE" LIGHT, "VSC TRAC" LIGHT, AND "TRAC OFF" LIGHT CAME ON AND THERE WAS A TERRIBLE GRINDING SOUND WHEN ATTEMPTING TO STOP. IT WAS VERY HARD TO STOP BUT LUCKILY I WAS IN A PARKING LOT WHEN IT HAPPENED THE FIRST TIME. THE "BRAKE" LIGHT HAS CONTINUED TO COME ON MULTIPLE TIMES PER WEEK SINCE MAY OF 2015 AND THE OTHER TWO LIGHTS STILL COME ON OCCASIONALLY. IN FACT, ON MY 800 FOOT DRIVE BACK FROM PICKING UP MY LUNCH TODAY, THE "BRAKE" LIGHT WAS ON. EACH TIME THE OTHER 2 COME ON, IT CAUSES THE BREAKS TO GRIND AND IT IS VERY HARD TO STOP. THERE WAS JUST OVER 120,000 MILES ON THE VEHICLE AT PURCHASE. I HAVE READ NUMEROUS FORUMS ONLINE STATING ISSUES WITH THIS MODEL, 2004, AND 2003 MODELS FOR THE SAME ISSUE BUT TOYOTA HAS REFUSED...

I BOUGHT A TOYOTA SEQUOIA 2005 BACK IN 2005 AT RICE TOYOTA DEALER IN GREENSBORO . TODAY , WHEN I WAS DRIVING ON THE STREET AND TURNED ON THE LEFT LIGHT SIGNAL WITH LESS THAN 15 MPH WHILE USING THE BRAKE, I HEARD A VERY LOUD GRINDING NOISE AND THAT INSTANTLY I SAW ALL 3 SIGNS ( TRAC OFF, VSC TRAC, BRAKE ) ON AT THE SAME TIME. I AM ALMOST OUT OF BREATH AND SCARED TO DEATH. THE SIGNS (TRAC OFF, VSC TRAC, BRAKE ) ONCE IN A WHILE APPEARED IN THE PAST AND DISAPPEARED BY THEMSELVE AND I DID NOT HAVE ANY SERIOUS PROBLEMS IN THE PAST , BUT TODAY THE CAR JUST ACTED LIKE A DEAD CAR AT THAT MOMENTARILY. I WAS SO SCARED AND SCARED. *TR

WHEN SLOWING TO A STOP, MY SEQUOIA PERIODICALLY GRINDS WHEN BRAKING AND THE VSC SENSOR, ABS SENSOR AND TRAC SENSOR LIGHT TURN ON AND STAY ON. *TR

WE NOTICED THAT OUR FRAME HAD SEVERE RUST LAST WINTER. (2/14) WE ALWAYS DID THE REGULAR RECOMMENDED MAINTENANCE. WE PURCHASED THIS NEW IN '05. I'M SURE OTHERS HAVEN'T REPORTED THIS AS THEY HAVEN'T LOOKED FOR THIS PROBLEM NOT EXPECTING IT FROM SUCH AN EXPENSIVE VEHICLE THAT YOU WOULD EXPECT TO BE VERY RELIABLE. WE DID PUT IN A CLAIM TO TOYOTA LAST FEBRUARY AND WE WERE TOLD THAT IT WASN'T A PROBLEM THAT THEY HAD MANY COMPLAINTS ON. I KNOW THERE WERE RECALLS IN THE PAST WITH TOYOTA VEHICLES THAT HAD THE TUBULAR FRAMES. THIS ALSO HAS A TUBULAR FRAME. WE ALSO HAVE THE SAME PROBLEM WITH VSC AND TRACKING THAT MANY OTHERS ON THIS SITE HAVE COMPLAINED ABOUT. *TR

WHEN ACCELERATING FROM LOW SPEED OR STOPS THE SEQUOIA ACTIVATES THE VSC AND THE TRACTION CONTROL SYSTEM AND REFUSES TO ACCELERATE. HAPPENS CONSISTENTLY BUT NOT CONSISTENTLY ENOUGH TO KNOW WHEN TO EXPECT IT. THE TRACTION CONTROL/SKID CONTROL LIGHT ACTIVATES FOR AROUND 5 SECONDS AND THEN VEHICLE RETURNS TO NORMAL OPERATION. IT CAN BE NERVERACKING. FROM ALL MY INVESTIGATION IT SEEMS IDENTICAL TO THE PROBLEMS THAT LED TO THE 2003 SEQUOIA RECALL. I DO BELIEVE THAT THIS IS A SIGNIFICANT SAFETY ISSUE. AGAIN FROM MY RESEARCH THIS IS A VERY COMMON PROBLEM AMONG MANY MODEL YEARS OF SEQUOIAS. *TR

WHEN TURNING AND ACCELERATING (FOR EXAMPLE, TURNING OUT OF A PARKING LOT AND ENTERING TRAFFIC) THE TRACTION/SKID CONTROL WILL ENGAGE - THE SKID CONTROL LIGHT TURNS ON - AND CUT THROTTLE FOR APPROXIMATELY 3 SECONDS. DURING THIS TIME THE VEHICLE SLOWS DOWN AND IS NOT RESPONSIVE TO PRESSING ON THE GAS PEDAL. THIS HAS HAPPENED APPROXIMATELY 10-15 TIMES ON THIS VEHICLE. I WAS NOT AWARE THIS WAS AN INHERENT SEQUOIA PROBLEM UNTIL I READ OTHER COMPLAINTS ONLINE - WHICH IS WHY I DID NOT REPORT THIS EARLIER. *TR

CAR HAD VERY LITTLE POWER WHEN PRESSING GAS PEDAL. TOOK TO TOYOTA DEALERSHIP WHERE THEY INDICATED THE "AIR INJECTION PUMP" REQUIRED REPLACEMENT. I PERFORMED THE REQUIRED REPAIR AND IT WAS $3,000. I'VE ALSO SEEN THIS IS A COMMON PROBLEM WITH THIS MODEL VEHICLE. *TR

VSC TRAC, ABS AND BRAKE ALERTS LIGHT UP ON DASH BOARD, NOISE WHEN VEHICLE IS INITIALLY TURNED ON, THE NOISE DISAPPEARS AFTER A FEW MINUTES BUT THE ALERTS STAY ON. THE VEHICLE ALSO LOSES POWER (BUT THE ENGINE KEEPS RUNNING, JUST NO POWER TO ACCELERATE) IF I MAKE A QUICK TURN, LOSS OF POWER LASTS FOR A FEW SECONDS THEN TURNS BACK ON. *TR

VSC TRAC---VSC--CHECK ENGINE LIGHT--AND THEN PROBLEMS WITH ACCELERATION!! *TR

ABS SYSTEM WOULD ENGAGE AS VSC SKID CONTROL LIGHT AND BRAKE LIGHT APPEARS. SYSTEM WOULD RESET AFTER IGNITION WAS TURNED OFF AND RESTARTED. MISHAP OCCURRED SEVERAL TIMES ON DRY, SMOOTH ROAD SURFACE AT A LOW RATE OF SPEED WITH MINIMAL PRESSURE ON BRAKE PEDAL. I TOOK CAR TO DEALER FOR REPAIR. THEY REPLACED SKID CONTROL ECU. CAR REPEATED SYMPTOMS ON MY WAY HOME. I TOOK IT BACK TO THE DEALER. THEY REPLACED BRAKE BOOSTER. CAR IS WORKING NORMALLY NOW. *TR

THE VSC TRAC, VSC OFF AND ABS LIGHT WOULD COME ON AND THEN RESET WHEN I TURN OFF & RESTART THE VEHICLE. I CALLED THE TOYOTA DEALER I TAKE MY CAR TO FOR MAINTENANCE AND THEY SAID TO BRING IT IN WHEN THE LIGHTS TURN ON AGAIN. I DID SOME RESEARCH AND WAITED FOR THE LIGHTS TO COME BACK ON. THE LIGHTS CAME ON TODAY & I TOOK IT INTO THE DEALER. THEY SAID THE MASTER CYLINDER AND SKID ECU WAS BAD & NEEDED TO BE REPLACED. THEY QUOTED ME $1900 PLUS LABOR. THIS IS AN EXTREMELY COMMON PROBLEM WITH THE SEQUOIA'S AND I AM VERY SURPRISED & DISAPPOINTED THAT THERE HASN'T BEEN A RECALL DONE FOR THIS PROBLEM. *TR

VSC TRAC, VSC OFF, BRAKE, ABS LIGHTS... ALL ON, ALL AT ONCE. THIS HAS HAPPENED SEVERAL TIMES NOW. IT COMES ON FOR A COUPLE OF DAYS AND THEN RESETS ITSELF NO CODES FOUND. THIS TIME IT CAME ON AGAIN AND LIMITED THE SPEED TO ABOUT 35MPH WHILE MY WIFE WAS DRIVING ON A MAJOR HIGHWAY. SHE WAS ABLE TO GET IT BACK HOME SAFELY THANK GOODNESS. I HAVE BEEN READING ABOUT SIMILAR CASES FOR THIS MODEL AND DO NOT KNOW WHAT TO DO.PLEASE HELP. WE HAVE JUST HAD IT SERVICED ABOUT A MONTH AGO FOR TIMING BELT REPLACEMENT ETC. THIS IS MY WIFE'S PRIMARY VEHICLE AND I CAN'T AFFORD TO PUT ANY MORE MONEY IN THIS. IS THERE A RECALL FOR THIS WITH SO MANY CASES OF THE SAME ISSUE I HAVE READ ABOUT? *TR

TRAC OFF, VSC TRAC ,ENGINE LIGHT CAME ON...TROUBLE CODE WAS P1444 (SECONDARY AIR INJECTION SYSTEM SWITCHING VALUE STUCK)...VEHICLE HAD PROBLEMS ACCELERATING. REPAIRMAN INDICATED THAT THE AIR INJECTION PUMP/CHECK VALUES NEEDED TO BE REPLACED AND VERY EXPENSIVE. BASED ON OTHER REPORTS IT APPEARS THAT THIS IS A FREQUENT OCCURRENCE AND VEHICLES SHUTTING DOWN ON INTERSTATES. OTHERS HAVE SAID THAT TOYOTA KNOWS ABOUT THIS BUT WON'T ISSUE AN EXTENDED WARRANTY, BUT OFFERS FOR NEWER VEHICLES . OWNED SEVERAL TOYOTAS BEFORE THIS...THIS COULD BE A DEAL BREAKER FOR FUTURE TOYOTAS. *TR

VSC, TRAC, ABS AND BRAKE LIGHTS WOULD ALL COME ON A ONCE. THEY WOULD USUALLY RESET AFTER ON THE NEXT START. IT HAS PROGRESSED OVER THE PAST YEAR TO THE LIGHTS STAYING ON MOST OF THE TIME AND ONLY OCCASIONALLY RESETTING TO OFF. I HAVE NO ABS OR STABILITY CONTROL DUE TO THIS MALFUNCTION. EVEN WITH THE LIGHTS ON, THERE WERE NO CODES ON SYSTEM WHEN I WENT TO THE DEALER. THEY RECOMMEND REPLACING THE SKID CONTROL ECU WHICH IS VERY EXPENSIVE. THIS SEEMS TO BE A VERY COMMON PROBLEM. *TR

VEHICLE WHEN ON A STOP AND MAKING A TURN DOESN'T ACCELERATE FOR A FEW SECONDS IT GOES BLANK THEN AFTER GETS SPEED. IN MANY OCCASION I HAD CLOSE CALLS WITH UPCOMING TRAFFIC BEHIND ME AFTER MAKING THE TURN BECAUSE OF THE ACCELERATION FAILURE. I CALLED THE DEALER WHERE THE CAR WAS OBTAINED AND THEY SAID THAT THERE IS NO RECALL FOR THAT VEHICLE EVEN WHEN I TOLD THEM THAT THE SEQUOIA 2003 WAS RECALLED BECAUSE OF THE SAME ISSUE. THE TOLD ME THAT THEY CAN CHECK WHAT IS WRONG WITH IT BUT I WILL NEED TO PAY THE INSPECTION PLUS THE REPAIRS. LAS CONVERSATION WITH THEM WAS 6/27/2014. *TR

WHILE DRIVING MY VEHICLE ON THE HIGHWAY TO WORK, MY BRAKE WARNING LIGHT ON THE DASH CAME ON. I PULLED OVER CUT THE TRUCK OFF THEN BACK ON, THE LIGHT WAS GONE. THE NEXT DAY DRIVING HOME FROM WORK, IT WAS POURING DOWN RAIN AND THE BRAKE WARNING LIGHT CAME ON AGAIN, ALONG WITH THE TRAC AND VSC WARNING LIGHTS. I WAS ONLY DRIVING ABOUT 25 MPH SINCE I WAS IN THE CITY AND NOT ON THE HIGHWAY YET. I PULLED OVER CUT THE TRUCK OFF AND THEN BACK ON, THE LIGHTS WERE OUT, BUT WITHIN ANOTHER MILE THEY WERE BACK ON. I AVOIDED THE HIGHWAY SINCE MY BRAKES WERE HAVING PROBLEMS AND IT WAS POURING RAIN. THE NEXT DAY THEY WERE OFF SO I DROVE BACK TO WORK BUT WHEN I WAS ON THE WAY HOME THEY ALL CAME BACK ON, THIS TIME IT WAS THE AFTERNOON AND NOT...

CAR STALLS WHEN PUT IN DRIVE AND WILL NOT DRIVE SAFELY. THERE IS A LOUD CLUNK WHEN BACKING UP. CAR DOES NOT HAVE POWER GETTING UP HILLS. TOYOTA MECHANIC SAYS THERE IS A BAD COMPUTER THAT HAS BEEN RECALLED IN 2004 MODELS. I *TR

THE VSC TRAC LIGHT IS ON , AND ENGINE LIGHT TOO. *TR

MY VSC, TRAC OFF, CHECK ENGINE LIGHT AND THE EXCLAMATION SING ALL CAME ON FOR THE FIRST TIME SINCE I BOUGHT MY SEQUOIA, AND IT STARTED JERKING AND WHEN I SET MY FOOT ON THE BREAK IT STARTS TO PULL, AS I GOT ON THE INTERSTATE MY SEQUOIA ACCELERATED ITSELF THE RPM WHEN UP TO # 5 IT REALLY SCARED ME I HAVE TO TAKE IT THIS MORNING TO TOYOTA TO HAVE IT CHECKED, I DO TRAVEL WITH MY CHILDREN ALOT AND THAT IS A SAFETY CONCERN FOR ME. *TR

VSC AND ABS LIGHTS ARE GOING ON AFTER HORRIBLE SHUTTERING SOUND FROM FRONT OF VEHICLE. MY WIFE HAS EXPERIENCED THIS FOUR TIMES ON A MAJOR HIGHWAY AND WE ARE CONCERNED ABOUT SAFETY. I HAD RECENTLY EXPERIENCED THIS LAST WEEKEND. THERE IS A SUDDEN LOSS OF CONTROL OF THE VEHICLE BEING AWARE OF THE EMERGENCY BRAKE IS THE ONLY WAY TO STOP THIS VEHICLE.TOYOTA HAS MANY COMPLAINTS ABOUT THIS AND THEY NEED TO RECALL THIS PROBLEM BEFORE SOMEONE GETS REAR ENDED ON A HIGHWAY. *TR

TRAC OFF, VSC TRAC , ABS AND PARKING BRAKE LIGHTS ALL CAME ON AND STAYED ON WHILE DRIVING. VEHICLE HAS BEEN DOING THIS INTERMITTENTLY FOR ABOUT A MONTH NOW ON A REGULAR BASIS. HAS DONE IT OVER THE PAST COUPLE YEARS BUT MAYBE ONCE EVERY SEVERAL MONTHS. RESETS AFTER VEHICLE IS TURNED OFF. LOOKED UP ISSUE ON INTERNET AND WAS SURPRISED TO FIND ALL THE POSTS ABOUT THIS ISSUE AND THE LACK OF TOYOTA TO RECALL WHATEVER IS CAUSING THIS ISSUE. *TR

WHILE DRIVING HOME ON INTERSTATE 15 IN CALIFORNIA BRAKE PEDAL WOULD NOT DEPRESS. AFTER SEVERAL HARD FOOT APPLICATIONS PEDAL FINALLY ENGAGED. THIS IS AFTER MONTHS OF SERVICE ON THIS VEHICLE FOR BRAKE PROBLEMS STARTING WITH SPONGY AND INCONSISTENT PEDAL AND VCS, ABS AND BRAKE LIGHTS COMING ON AND STAYING ON. DEALERSHIP REPLACED ON BOARD COMPUTER, BRAKE BOOSTER, BRAKE MASTER CYLINDER, BRAKE PADS AND PROBLEM STILL THERE. I AM THE ORIGINAL OWNER AND BOUGHT THIS VEHICLE NEW. THIS IS A SERIOUS PROBLEM AND JUST A MATTER OF TIME BEFORE AN ACCIDENT OCCURS. THIS VEHICLE IS NOW BACK IN THE SHOP ONCE AGAIN. *TR

I WAS TOLD THE VEHICLE CONTROL AND STABILITY SYSTEM WAS OFF. AND IS A COMMON ISSUE WITH THIS YEAR MAKE AND MODEL. VSC AND TRAC OFF LIGHT KEEPS COMING ON. ALSO SECONDARILY VALVE STUCK CLOSED. P1445 & P1442 CODES. ALSO ANOTHER KNOWN ISSUE FOR THIS VEHICLE YEAR MAKE AND MODEL. TOYOTA IS AWARE BUT WON'T FIX AFTER CERTAIN MILES. *TR

AFTER CRANKING THE CAR AND DRIVING FOR A FEW MINUTES, THE FOLLOWING LIGHTS ON THE DASHBOARD APPEARED: VSC OFF / VSC TRAC / CHECK ENGINE LIGHT. I ENTERED THE ON RAMP TO THE INTERSTATE AND COULD NOT ACCELERATE PAST 40 MPH. HAD TO PULL OVER AND LET THE CAR "RESET". ATTEMPTED TO RE-ENTER THE INTERSTATE AND THE FLOW OF TRAFFIC BUT CAR WOULD NOT ACCELERATE BEYOND 40 MPH AND I HAD MY 3 SMALL CHILDREN IN THE VEHICLE. VERY TERRIFYING EXPERIENCE. DROVE TO A DEALERSHIP THAT ADVISED ME A SECONDARY HOSE HAD TO BE REPLACED ON THE ENGINE. LATER DETERMINED THAT TOYOTA RELEASED A TECHNICAL BULLETIN AND ARE AWARE OF THIS ISSUE BUT WILL NOT ISSUE A RECALL. IT IS AN EXTREMELY COSTLY PART TO FIX. PARTS ALONE ARE $3200. *TR

DRIVING VEHICLE AND ABS ACTIVATES AND STALLS VEHICLE NOT ALLOWING FOR ACCELERATION PULSATING THE BRAKES AND LEAVING ME IN THE MIDDLE OF THE ROAD FOR ABOUT 30/45 SECONDS. IT HAS HAPPEN TWICE ALREADY SAME THING BOTH TIMES. *TR

WHILE APPLYING THE BRAKES THERE IS A GRINDING NOISE COMING FROM THE FRONT OF THE VEHICLE WITH A SHUDDER AND THE VSC, TRAC OFF AND BRAKE LIGHTS COME ON AND STAY ON. THIS HAS HAPPENED SEVERAL TIMES RECENTLY. ALSO THE BRAKE LIGHT WILL COME ON AT RANDOM TIMES. EVERYTHING RESETS WHEN THE IGNITION IS TURNED OFF. WHEN THE VEHICLE SHUDDERS IT DOES NOT SEEM TO BE SLOWING DOWN. I HAVE CHECKED THE TOYOTA WEB SITE AND THEY DO NOT SHOW ANY RECALLS. ALSO I HAVE CHECKED ON-LINE AND THERE ARE SEVERAL PEOPLE THAT SEEM TO BE HAVING THE SAME PROBLEM. THIS IS A VERY UNSAFE PROBLEM AND I FEEL THAT TOYOTA NEEDS TO FIX THIS WITH A RECALL. THEY ARE AWARE OF THE PROBLEM AND IT IS VERY EXPENSIVE FIX. *TR

WHILE DRIVING STRAIGHT DOWN THE STREET, I HEARD A GRINDING SOUND AND ALL OF THE VSC TRAC WARNING LIGHTS CAME ON. AFTER STOPPING AND RESTARTING THE CAR, THE CAR BEHAVED NORMAL AGAIN. THIS IS THE SECOND OCCURRENCE. I'M PRESUMING THAT THE GRINDING NOISE MIGHT BE THE BRAKES PULSATING. IT IS NOT SAFE FOR THE BRAKES TO AUTOMATICALLY APPLY THEMSELVES DURING SAFE DRIVING CONDITIONS. *TR

LOSS OF ABS SYSTEM, VSC & TRACTION CONTROL ON INTERSTATE AT HIGH RATE OF SPEED BARELY AVOIDED COLLISIONS. UNSAFE. VSC/ABS/E BRAKE LIGHT ALL ON. *TR

MY VSC, TRAC AND BRAKE LIGHT ALL CAME ON ALL OF SUDDEN WITH A LARGE BOOM SOUND. THE CAR STALLED ON ME IN AN INTERSECTION. THE LIGHTS GO OFF ONCE CAR IS TURNED OFF AND THEN AFTER TURNING CAR BACK ON THEY WILL COME ON ABOUT 5 MINUTES AFTER DRIVING. CAR LOSES POWER EVERY SO OFTEN NOW. DEALER SAID IT NEEDS A NEW COMPUTER. *TR

I NOTICED THE VSC TRAC LIGHTS STAYED ON. THE VEHICLE APPEARS TO DRIVE FINE FOR A WHILE, THEN LOSES POWER. DEALER COULD NOT FIND ANY CODES AND RESET IT. HOW IT DOES IT ALL THE TIME MOSTLY ABOUT THE 2 OR 3 DAY AFTER UNHOOKING THE BATTERY. AFTER DOING MY OWN RESEARCH ONLINE I DISCOVERED THAT MANY SEQUOIA OWNERS HAVE EXPERIENCED THE SAME ISSUE, BUT TOYOTA HAS REFUSED TO DO A RECALL. THIS ISSUE WITH VSC TRAC IS A HUGE SAFETY CONCERN. THROUGH MY RESEARCH I DISCOVERED THAT THE VEHICLE COULD LOSE POWER AT ANY TIME, AND MANY OWNERS STATE THEY HEAR A GRINDING NOISE AS THE VEHICLE PULLS TO THE RIGHT OR LEFT. THEY RECALLED THE 2003, WHAT ABOUT US, A FRIEND HAD A NEW COMPUTER EPU PUT IN AT $3000 AND DID IT AGAIN IN 6 MONTHS...TOYOTA KNOWS ABOUT THIS AND OTHER PROBLEMS...WE NEED A RECALL OR HAVE...

THE BRAKE LIGHT CONSTANTLY GOES ON AND OFF. TRAC OFF, VSC TRAC AND CHECK ENGINE LIGHTS ALL COME ON. A LOUD RATTLING NOISE COMING FROM THE FRONT END OF VEHICLE AND VIBRATION THE ENGINE WILL NOT ACCELERATE RANDOMLY WHILE DRIVING AND THE TRAC CONTROL LIGHT GOES ON AT THE SAME TIME. *TR

WHEN BACKING OUT OF GARAGE AND APPLYING BRAKES, THE ABS MOTOR WAS HEARD AND THEN THE BRAKE LIGHT CAME ON. THEN THE VSC TRAC, VSC OFF AND ABS LIGHTS CAME ON. THE BRAKE PEDAL FELT MUSHY SO A VISIT TO DEALER WAS MADE. THE CONCERN WAS ADDRESSED WITH SERVICE, AND THEY CAME BACK WITH : "TEST DROVE CAR AND INSPECTED BRAKES. FOUND DTC'S C1223, C1244, C1247, C1310. PROVIDED ESTIMATE FOR UPDATED SKID CONTROL ECU @ $905 + TAX". AS THE CUSTOMER, I DECLINED TO SCHEDULE. THEN DURING A PAST WINTER STORM, BACKING OUT OF DRIVEWAY AGAIN, THE SAME THING OCCURRED. VERY CONCERNED THAT THIS BRAKING SYSTEM IS DEFECTED IN ANY WET/SNOWY/ICE WEATHER. I HAVE HAD TO DIVERT TO DRIVING MY 1998 HONDA ACCORD IN SNOW INSTEAD OF THE SEQUOIA. I AM VERY CONCERNED DRIVING THIS SEQUOIA WITH MY KIDS IN CAR AND BRAKING AT ANYTIME. I FEEL AN UPDATED SOFTWARE/LOGIC...

THE VSC, TRAK LIGHT AND ABS LIGHTS CAME ON WHICH IN TURN MADE THE CHECK ENGINE LIGHT COME ON. THEY STAY ON CONTINUALLY. AT FIRST NO CODE COULD BE FOUND. THEN DEALER STATED THAT THE ECU HAD TO BE REPLACED AS WELL AS AIR PUMP - BOTH TOTALLING OVER $3000. THIS IS NOT THE ONLY SEQUOIA TO HAVE THIS HAPPEN. OTHER YEARS HAVE BEEN RECALLED SO WHY NOT THE 2005 - OR ANY OTHER YEAR SINCE IT SEEMS TO BE AN ISSUE. I EMAILED AND TALKED TO TOYOTA. THEY HAVE NOT HEARD OF THIS PROBLEM AND CAN NOT HELP WITH IT'S SOLUTION. LAST TOYOTA I'LL HAVE. *TR

MY VSC TRAC, VSC OFF COMES ON ALL THE TIME AND DON'T GO AWAY. THIS APPEARS TO BE A MANUFACTURE ISSUE. *TR

SLOWING DOWN TO TURN THE VSC TRAC< TRAC OFF < CHECK ENGINE<BRAKE LIGHTS COME ON. THIS HAS HAPPENED THREE TIMES AND I TEMPORARILY LOSE CONTROL OF BRAKING AND EXCELLERATION. THIS IS DANGEROUS AND NEARLY CAUSED ME TO ENTER TRAFFIC IN AN INTERSECTION. *TR

WHILE DRIVING, THE BRAKE WARNING LIGHT, VSC OFF LIGHT, AND VSC TRAC LIGHT ALL CAME ON. PULLED OVER AND SHUT ENGINE OFF. RESTARTED THE CAR AND LIGHTS WERE INITIALLY OFF BUT CAME RIGHT BACK ON AS SOON AS I STARTED DRIVING. HAD ADVANCE AUTO PARTS HOOK COMPUTER TO IT, AND IT ISN'T THROWING A CODE AT ALL. *TR

3 INCIDENTS IN THE LAST 90DAYS, EACH ONE WHILE THE VEHICLE WAS IN MOTION BETWEEN 15-40MPH WITH 5 PASSENGERS AND IN TRAFFIC. ON EACH OCCASION, THE BRAKES SUDDENLY ENGAGED, CAUSING A LOUD BANG/THUNK SOUND FOLLOWED BY A SEVERE SHAKE IN THE VEHICLE. SPEED & CONTROL WAS DRASTICALLY REDUCED TO THE POINT OF BEING UNCONTROLLABLE. WITHIN SECONDS, THE VSC TRAC, VSC OFF, BRAKE AND MAINTENANCE LAMPS ILLUMINATED. VEHICLE WAS VERY DIFFICULT TO DRIVE, AS IF THE BRAKES WERE FULLY ENGAGED. AFTER PULLING OVER, WE SHUTDOWN THE VEHICLE AND LET IT SIT A SHORT PERIOD OF TIME, ON RESTARTING, ALL LAMPS WERE ON, THE VEHICLE WAS DRIVE-ABLE HOWEVER, THE BRAKES WE STILL BEING APPLIED BUT SLIGHTLY ALLOWING THE VEHICLE TO MOVE BUT ON RELEASE OF THE ACCELERATOR, THE VEHICLE SLOWED RAPIDLY. AFTER DROPPING OFF VEHICLE TO A LOCAL NON-DEALER SERVICE CENTER ON EACH OF THE FIRST 2 INCIDENTS, THE CODES WERE NO-LONGER...

THE BRAKE LIGHT CONSTANTLY GOES ON AND OFF. TRAC OFF, VSC TRAC AND CHECK ENGINE LIGHTS ALL COME ON. A LOUD RATTLING NOISE COMING FROM THE FRONT END OF VEHICLE AND VIBRATION WHEN STARTING UP THE VEHICLE. ENGINE WILL NOT ACCELERATE RANDOMLY WHILE DRIVING AND THE TRAC CONTROL LIGHT GOES ON AT THE SAME TIME. I FIRST EXPERIENCED THIS WHILE GOING UP A MOUNTAIN AND NEEDED TO TURN AROUND BECAUSE MY VEHICLE STARTED TO DECELERATE EVEN WITH THE GAS COMPLETELY FLOORED. I NOTICED THAT THERE ARE A LOT OF COMPLAINTS FOR THE SAME ISSUE. IS TOYOTA WAITING FOR A DEATH TO HAPPEN BEFORE THEY DO SOMETHING. THIS IS A FAMILY VEHICLE AND I'M TRANSPORTING MY 2 AND 5 YEAR OLD. SOMETHING NEEDS TO BE DONE ABOUT THIS BEFORE SOMETHING TRAGIC HAPPENS!! *TR
