Toyota sequoia - consistent failure of the traction control system while driving. this issue has been addressed by the dealer multiple times to no successful repair. we also have had significant issues with the rear window seals leaking and causing the window motor to fail. *nm

A few months after we purchased the vehicle in december 2004 we noticed that the traction lights are coming on periodically. we took the car to toyota service to check the issue and been charged hundreds of dollars for diagnosis and sensor replacement. however the problem was not solved and even got worst: the traction and brake lights were continuously on now. in 2010 we received a notice about a recall with regard to the above issue and brought the car to toyota dealership located at 4248 morse rd., columbus, oh 43230. the car was serviced but a few hours afterwards all the lights were on again. when we returned to the same dealership with the same complaint we were told that the recall was on the vehicle computer adjustment, which was done, and that and any additional services will be charged in full. we looked up the recall document and realized that it is clearly specified under remedy that: if the reflash cannot be completed on a particular vehicle, the ecu will be replaced with a new one. this service will be performed free of charge. since the manufacturer dealership is refusing to comply with the recall requirements we would like to bring the issue to your attention and seek your intervention. *tr

We own a toyata sequoia ltd 2003 model year. we took the vehicle several times to the dealer regarding braking issue. if we ever used the emergency brake, for some reason the right side front and rear brakes will start to lock up, that would shake the suv and we had to pull over. the dealer never determined what the problem was even though we ended up paying for repairs that never made a difference. eventually we stopped using the emergency brake on our vehicle, that also stopped the right side wheels from locking up. during this period the car parked in our driveway also crashed into our garage and broke the garage doors. with emergency brakes on and in park, middle of the night we there was a loud bang, the suv had crashed into the garage; even though the suv was in park position gear and with emergency brakes on. *tr

When we first bought the vehicle the trac system lights kept coming on and the brakes felt mushy; we took it in to toyota and they replaced the computer system which seemed to rectify the problem. then about 9 mo to a year later the lights kept coming on again and the brakes failed twice, toyota stated they would replace the brake system fluid and the master cylinder at our cost because we had taken it elsewhere and they felt that it had contaminated brake fluid, which our mechanic stated in writing was not. although we tried numerous times to have toyota fix it under warranty; we got the vehicle repaired through our own mechanic and then shortly later the brakes failed resulting in a crash on the freeway. when it was decided that the seq would be repaired via ins there was a code that showed up on the computer system that showed that brakes indeed did fail; however when taking it to toyota the same code did not show up. the vehicle did well, however we live by a dirt road and when traveling down the road or going around a corner quickly the trac system lights go on and now the vehicle acts like it won't go when the trac system is on and you slow down or start up again--at present the system is turned off; it has really never worked correctly. *nm

While consumer was driving the check engine light/trac light, and abs braking light appeared on the dashboard and remained on. then, vehicle stalled. consumer was unable to restart vehicle, and had vehicle towed to dealer for inspection. mechanic determined that the battery needed to be replaced. consumer informed mechanic that this problem recurred and had not been resolved. *ak

The vehicle skid control and traction control light came on intermittently and caused the vehicle to lose rpm's and had no throttle response. the indicator lights flickered and the rpm's dropped and there was no control with the acceleration. provide further details. *jb

Dt: brake system will grab and throw car into skid, but parts are failing intermittently. the switch on the dashboard does not shut it off. consumer had no control of vehicle. it has been in the repair shop, and found out steering angle sensor was bad, and replaced it. also, computer was defective. *ak the vehicle's computer was replaced also. the technician could not confirm what failed first, why either failed, or why he could not find any trouble over one year ago, when consumer noticed blinding lights on the dashboard. the consumer feels that this is a safety hazard because drivers do not have control over this active 4 wheel drive system. also the dash control will not shut off vsc (vehicle skid control), nor any other fuse, switch, wire, or other vsc's.*sb

Vehicle skid control (vsc)continues to fail, taken the sequoia to toyota several time and the reset or change the vsc module. toyota knows this is a problem on all sequoias but don't appear to interested in fixing it. *tr

We purchased a 2003 sequoia in august of 2003. the first thing that happened was the hood latch came off no biggie a $10 replacement everything a ok. next came the oil pressure gauge it always read low. i took it to the dealership and was fixed, the cause was a faulty sender, no charge to me. on a routine oil change i asked for the alarm to be check because it was always silent. to my surprise the horn had come off lucky for me it was still under warranty so it was replaced. all this time the vsc/ trac off light keeps coming on. the dealer can't come up with a problem and they say just restart the car and they should come off. now there is a grinding sound coming from my dash and the lights are coming on again so off to the dealership again. they can't duplicate the sound and the lights well maybe its my brakes and i have to get those replaced. i decided to wait on that. ok now since my kids like to ride with the back windows down and i can't stand the pressure and sound in the car. (it sound as if i'm in a helicopter) i decide to roll the back window down to stabalize the pressure and what do you know it doesn't work and now my vsc / trac off and abs lights are all on "all the time" . now i'm at the dealership again (everyone there knows me by name now) . the vsc/ trac off and abs light well that was a sensor that needed replacing and the window well guess what that was the grinding sound i had heard before . the motor needed to be replaced. be ready to pay about $800 in parts and labor. lucky for me i had purchased the extended warranty so i was left with just my deductible. i have owned 3 toyotas in the past and have always had that peace of mind "its a toyota" but now i'm not so sure. toyota is not what it used to be. i still love the space and comfort of the sequoia but would rather do without all the service trips to the dealership.
