Problems with 2003 Toyota Sequoia VEHICLE SPEED CONTROL

Vsc and abs lights come on in 2003 toyota sequoia. dealers request that the sensor or ecu be replaced out-of-pocket ($700 - $2000). a lot of complaints have been filed by 2001-2003 sequoia and tundra customers but toyota refuses to issue a recall. *tr

Vsc trac and vsc and brake lights come on and sometimes can be reset by turning the car off and then on. loss of power when this happens sometimes. lately this has been happening on a regular basis. *tr

On several occasions after backing out of the driveway and beginning to accelerate the vsc light comes on and a strange sound is heard from under the truck. the tires are either slipping on snow at the time or loose gravel leftover from the snow. toyota dealership said we need to replace the ecu unite for $1000 because it's not covered in the may 2010 recall based on our vin number. *tr

Vsc and vsc of lights are oncodes c1223 abs control system malfunction, c1231 steering angle sensor, and c1247 stroke sensor indicates needs the skid control ecu t 2.0 replaced skid control ecu 08/01/2010 check engine light found p0031 af sensor b1s1 t1.0 parts replaced. 6/01/2013 again vsc trac off service engine light on and dealership wants 1400.00 for new computer. *tr

My complaint is the abs/trac control system in my toyota sequoia. it engaged without any reason and i lost power when i was driving in a hot day on the freeway. i had to pull over. there are many other owners who are reporting this issue on many websites. does someone have to die for you guys to take any actions. *tr

The vehicle stability control (vsc) lights keep coming on at random and will not turn off until the engine is restarted. there was a voluntary recall from toyota for this problem but the dealer said mine is not affected but obviously it is since i received a notice and the lights do come on. i also hear grinding noise when the abs engages. toyota dealer wanted to charge me for the fix. *tr

Abs, vsc/trac lights are "on" all came up at the same time. it was a rainy day in houston, tx. had to run 55mph at 65mph speed limit due to rain for safety pre-caution. at the time i reached my work place (approx 10miles from my residence), all 3-lights (abs, vsc, trac) turned on. i am the 2nd owner of this vehicle, acquired it from toyota dealer 15 october 2009. with this incident, got curious of any recalls, complaints or issues with 2003 sequoia. unfortunately, i just realized that i am among owners having the same issues. *tr

Vech. skid control alarm and reaction takes place without warning or justification. vehicle brakes come on with warning and car shakes because the brakes which are automatically being applied and brake anti skid system is activated. this happened when traveling approx 45 mph. thought i was going to die because of the violent reaction of the vech. this has happen more than five times and toyota wants me to pay $2,100 to correct their engineering error. should i submit a bill for mental anguish? *tr

I own a 2003 toyota sequoia sr5 with 95000 miles. vsc, trac, and abs lights came on. dealership said that the codes are faulty ecu. cost of repair was $1700. the following week lights came back on. this time they tell me it is a faulty speed sensor on the front right. they recalibrated the vehicle and said if it comes back the cost of the repair is $400. following week, the lights come on, same code for the speed sensor, so i have it replaced. two days later, the lights are back on. not certain what will code this time. after reading several posts online, it looks like this is a recurring issue with this vehicle. so, i'm filing a complaint sense there hasn't been a recall.*tr

Driving home and all of the sudden the vsc/trac/ and abs light go on. toyota says it is not dangerous but the manual says to take it in asap. spent ~$1000 to replace the control unit. *tr

a vsc/ abs/ skid lights starts to trigger on my 2003 toyota sequoia limited 4wd which will create unnecessary grinding sound... *tr

While driving along at city street speeds, during dry weather, on paved roads, my vsc trac and trac off lights come on. no other warning lights come on. then a buzzer sounds for about 3 seconds. then at the same time, a strange grinding sound comes from underneath the car, and the brakes seem to start working for no reason. i quickly pull over, turn off the car. i check the outside of the car and see no indication of running over anything. i then start the car and all the lights are back to normal (off). this happens about 2-3 times a month, for about a month or 2 now. i have not been able to determine any problems. *tr

I have a 2003 toyota sequoia 4x4. i had the 60,000 mile service done at piercey toyota milpitas, ca. i received a call from the service department advising me that the vehicle battery needed replacement, which i authorized. when i picked up my vehicle, i noticed that the vsc/vsc traction light was on and would remain on. i brought the vehicle back to piercey toyota, and they advised me that the vsc computer needed to be replaced. the cost for replacement was $2,000. i declined repair until i could do some research. i have checked the web, and apparently there are numerous complaints regarding the premature failure of the vsc computer. your nhtsa action number is pe08072. i have no way of proving it, but i think when the new battery was installed, the vsc computer was damaged, since it had worked fine until the 60,000 mile service/vehicle battery replacement. *tr

I have had the same problem as detailed in nhtsa action no. pe08072. several times, my vehicle stability control system has activated unexpectedly. every time, it happened when i was at a stop sign. when i accelerated to turn right, the vsc system activated and i lost power to the vehicle, half-way pulled out in a turn. after several seconds, power returned. *tr

Tl*the contact owns a 2003 toyota sequoia. the contact stated that while driving in snowy weather at 28 mph, the vehicle suddenly accelerated, skidded to the left and crashed into a field. there were no injuries but a police report was filed. the vehicle was taken to an independent repair shop where the body was repaired. the acceleration problem had not been addressed at the time of the complaint. the contact believed the failure occurred because of the electrical system. the failure mileage was approximately 95,000. the current mileage was approximately 139,000.

For no reason, the traction control system lights (vsc trac) have lit up and will not turn off. after researching the matter, it appears this is a common failure of the vsc traction control ecu. the approximate cost to repair is $2000.00. this item is currently being considered for a recall as its a widespread problem for all toyota sequoias. *tr the vehicle does in fact experience the occasional locking up of the brakes coupled with the loss of ability to accelerate. this occurs several times a week and usually occurs after coming to a stop and you begin to accelerate forward again. as you begin to accelerate, the vehicle suddenly loses power and the brakes lock up and make a loud griding noise. while this occurs, if you step on the brake pedal, its very firm and you can feel a vibration in the pedal. *smch

I bought 2003 toyota sequoia. i am getting the vsc traction control and abs light on. checked with other sequoia owner and they have similar problem. i went to checked the car and was told that the ecu computer is faulty. the faulty ecu needs to be replaced. since this is wide spread problem with 03 sequoia it should be recalled. this is a safety issue. here are the codes: c1203, c1223,c1244. *tr

Vehicle stalls occasionally when making a right turn. this happened to me while pulling into traffic which made for an extremely dangerous situation as i have to quickly steer the car over to the side of the road. after starting the engine, vsc off light is illuminated and stays on. when putting vehicle in gear and driving for a few seconds, a grinding noise with a warning signal occurs. *tr

03 toyota sequoia vsc trac lights on. safety concern. *tr

2003 sequoia bought in nov 2002. currently only have 20,474 miles. 1-1/2 yrs after buying car, brake light kept coming on. took to 3 different dealership and no one could figure out what was wrong. finally, on 4th attempt, they said it was skid control board. they initially tried to charge me to fix it, but ended up doing under "good will." now, a few months later, the abs, vsc and track lights are coming on and the dealership said i need to replace the yaw sensor. they know and i know it is all related to the skid control system, but they want to charge 423.00 + tax to replace it. i think it should be free, considering the common problem they have with the skid control system. my warranty has expired and i don't have an extended warranty. *jb

Vsc lights are on. my vehicle has less than 26,000 miles on it. *tr

2003 toyota sequoia (2wd) without warning the vsc/trac system engaged while turning on dry pavement causing a loss in acceleration. this was the initial incident which was followed by multiple other incidents at random intervals. incidents occurred while making both left and right turns from a turning or stopping position. trac off "button" does not disengage the system as indicated in the owner's manual from a low speed. local dealership ran diagnostic test and recommended new tires/brakes but could not identify any "problems" with the vsc system other than the vsc system had engaged. after 4 new tires and new rear brakes were installed service tech drove vehicle and experienced the issue. he recommended documenting when the incidents occurred and under what circumstances in order to determine repair options. the vsc system continues to engage randomly causing a loss in acceleration when this occurs and is dangerous if driver has need to pull into traffic in instances such as turning onto major roadways. *tr

2003 toyota sequioa vsc/trac saftey problem. starts with the dash lights appearing and then can turn suv off and/or turn brake lights off. a definite safety problem. toyota really should recall. *tr

The vcs and traction control light came on and the vehicle started to brake by itself. this was a sudden deceleration without warning. *tr

'2003 toyota sequoia vsc/trac/abs indicators based on edmunds.com forums an increasing number of problems may contribute to uncontrolable accidents if this electronic computer is not fixed. toyota dealers inidicate if an issue, car will resort back to conventional brakes & steering but examples on this were showing falsely. this appeared to need a fix immediately as the item was. ball joint) recalled about 1-2 yrs ago, and now the problem was surfacing again.*ak

Vsc traction and abs control warning lights stay lit. lights would go on and off and now stay lit all the time so have no warning if abs system is functional or has other issues. lost the ability to turn traction control on/off. took vehicle in for service at dealer, 3-26-07, and was informed it was a manufacturing defect with an internal component, yaw rate sensor. reported to toyota and requested assistance in repairing as this appeared to be a manufacturing defect. toyota denied claim. have seen vehicles produced 1 month earlier are now under recall for similar issues nhtsa campaign # 10v176000. dealer cost to repair at time was $1433. have experienced braking oddities on occasions. *tr

Vsc and trac and abs lights come on 2003 sequoia with 38,000 miles for no reason. dealer says yaw rate sensor bad but have had problem with these lights since purchase in 2003. apparently, many sequoias from 2001 to present have problems like this. toyota needs to be do something.

Unintended acceleration, increased acceleration despite stepping on brake, , brakes did not stop car and crashed total loss. *tr

On my 2003 sequoia with 50k miles, i believe i have an extremely dangerous situation! on turns, especially right turns when trying to accelerate into fast moving traffic i experience a total loss of power with no acceleration. i can pumping the gas pedal and press it to the floor, but i just coast slowly into the oncoming traffic and wait to be possibly rear ended. this happens in dry road conditions, and seems to occur more often when the engine is cold. my skid/traction lights blink for a second or two, then i re-gain engine power another second or so after that. i have also noticed my steering has become very stiff when driving in very slow situations 2-4 mph (parking lots, driveway etc.), i don't know if this is related. thank you, dave frazee - strongsville, ohio. *nm

Vsc llights in my 2003 toyota sequoia have come on multiple times, the car has already been back to the dealer for repar 4 times, it seems that they either do not understand what is causing the problem, or toyota is unwilling to admit that there is a serious defect in the car. the vsc light seems to now come on in the morning when the car is cold, and will then shut off if the car is restarted. dealer has been notified and now waiting to see if any actions are taken. *jb

2003 toyota sequioa, vsc lights/vsc tracking lights come on and make grinding noise once it is triggered it stays illuminated and the vehicle must be returned to dealership, and now this third time the check engine light appears, and is staying illuminated. this problem has happened for the 3rd time in four months. it is ridiculous. checkered flag toyota, va. beach, va. is the dealer with who has looked at the vehicle. *ak

2003 sr5 sequoia with 4700 mi, and two accelerator problems: 1. surging from a stop and when accelerating out of a turn. 2. a dead accelerator for a period of six to ten seconds when accelerating out of a turn. the engine does not die it just remains at an idle for the six to ten seconds while the driver is pressing on the accelerator pedal. these two problems are not constant they just happen from time to time. three trips to the dealer so far results in the response "unable to duplicate problem". the first failure date is the day we drove the vehicle home for the first time and continues to now.

While driving and upon pressing the accelerator vehicle lost power, and will not move. this happened three times. consumer had the vehicle towed to the dealership three times. the problem had not been resolved. vehicle was taken to dealer for repairs again for the same problem. *ak

Since taking ownership of my vehicle we have been having trouble with it. when taking a turn the vsc skid light comes on and the accelerator looses power. the vehicle doesn't stall but the gas pedal is unresponsive leaving you stuck for 2-5 seconds. it is extremely dangerous and i have almost been in an accident numerous times. we have taken it back to the dealership multiple times and they can't correct the problem because they can't replicate it. we had a district manager for toyota look at the vehicle and couldn't help us either. however, he did tell us that the newer model toyotas have been updated so this problem doesn't happen. that leads me to believe they are aware of the defect. it is happening multiple times a day now and i am afraid for the safety of myself and my children. i need help. *tr

Concern started with a vsc and traction control warning lights in instrument cluster coming on and off in an intermittent fashion without pattern or external cause. the warning lights would not remain on but instead would glow for a brief bit of time and then extinguish. the vehicle did exhibit a spontaneous deceleration on several occasions while operating at low speed (less than 20 mph) and on level, smooth ground. the episodes were brief and normal brake operation return immediately once speed dropped to approximately 5 mph. in the decades that i have operated this automobile, the warning lights went from lighting intermittently to being illuminated continuously; the spontaneous breaking has seemingly ceased since these lights have remained on. dealership and factory were informed of this concern with each service visit. dealership response was that they were unwilling or unable to diagnose an intermittent concern. once the lights remained on, i was initially informed that they suspected a defective yaw sensor and more recently, malfunctioning brake booster components; warranty period had lapsed and no extension was offered. attempts to correctly diagnose and repair this concern have dragged on for 10 years with dealership and factory position that repairs, be they diagnostic (the yaw sensor replacement) or definitive (booster and brake system), were not warranty issues despite their intermittent presentation during the warranty period. my periodic practical testing of the brakes demonstrates that the abs system functions properly despite warning light indications to the contrary. current dealership estimated cost to replace brake booster and actuators is $3800 with a 12 month warranty. toyota usa's position is this is not a warranty issue as of april 2013. *tr

2003 toyota sequoia limited, 5 months old, 5200 miles, check engine light came on at the same time as vsc lights. seems to be other reports of same incident. also, brakes seem to be inadequate for vehicle weight with loing stopping distance, and significant travel when parking brake applied (low pedal)*ak

While driving at any speed consumer heard a loud noise coming from the front of the vehicle. consumer applied the accelerator pedal and the vehicle failed to accelerate. then, consumer again applied the accelerator pedal numerous times and the vehicle accelerated uncontrollably. he was able to maintain control of the vehicle, and drove it to the dealer for inspection. mechanic could not duplicate the problem. *ak
