When the vehicle is in motion the vsc trac lights come on and the brakes active on their own causing the cracking noise and a rough jerk motion to the car. this has happened several times both on the highway and city streets even when driving 10 miles per hour
On multiple occasions recently while driving on the highway in a straight line manner, the rear brakes either the left or right have automatically engaged causing my sequioa to jerk to the left or right while at highway speed. my vehicle jerks violently, a buzzer sounds, and the vsc and trac lights illuminate and remain illuminated. if those lights are illuminated it no longer does this; however, if the lights are not illuminated it's a coin flip whether being jerked to the left or right while driving in a straight line on the highway. toyota dealership doesn't know what problem is. apparently it could be a dozen different things and they have to start replacing each one at a time to see if the problem goes away. to replace everything is several thousand dollars, probably more than the book value of the vehicle.
I forgot to mention in complaint 11282925 that some of the dozen parts needed to fix the vsc problem have been discontinued by toyota. so i could pay the dealership thousands to replace some of the possible culprits but the real problem could be the items that toyota discontinued. toyota cannot isolate what the exact problem is and has to replace possible culprits to see it it fixes the problem. after all of this and a huge repair bill could still have the highway safety problem if the faulty part(s) are the ones that have been discontinued. replacing items one at a time and then driving it on the highway to see if it's safe is not a good strategy. toyota should recall and fix all items at the same time and also produce the parts they have discontinued as a way to possibly try to cover up their negligence.
During driving on freeway with clean dry road car has beeping alarm on, vsc traction light on and svc lights lit up while the car shakes line the brake is on by itself for short period (3 seconds). then both warning light vsc and off and vsc track light is on still until the engine is turned off an hour afterward. the next day i drove the car slowly on a local street after picking up my son after school, the brake started shaking the car and vsc off and vsc track lights are on again. i drive the car with caution everytime after that but the occurance doesn't happen every time nor being recreate. it happened every few thousand miles unexpectedly. this is very dangerous . i would like to find a fix by the manufacturer and have them pay for it. it seems like this is a problem for many same cars .
The first indication that something was wrong was the first week of september 2019. i was driving down a county road when the lights indicator lights for the trac and vsc started flashing and beeping when i drove over some bumps. the lights would not go off even when pressing trac off. i turned off the car and restarted it and the lights were off but only for about 15 minutes into my drive. i took it to the toyota dealership and the agent said he did not know anything about the system and i would have to bring it back for diagnostics. that night i was getting ready to go over a rather large bridge when all of the sudden the car jerked twice to the right with the second event pulling me off the road. it was extremely frightening and terrified us all. thank god it did not happen on the bridge or under other circumstances. the vsc and trac lights came on at approximately the same time as they had been off. i contacted toyota corporate and essentially they said that the vehicle was not under warranty. ...
Just driving along, and feels like brakes grab and jerk the wheel and vsc trac lights go on. problem has been occurring intermittently. can be at highway speeds, but also happens at any speed. very dangerous and scary. vsc-trac and trac-off lights randomly illuminated on dry, level pavement when brakes were applied, causing a loud grinding noise (much louder than normal application of anti-lock brakes).
Tamara recall: i was going 60 mph when my traction control lights started blinking. it started making a grinding noise and front end shaking and loss of power steering it has 190,000 miles on it
Driving the vehicle at about 60mph, grinding sound, loss of power steering control, pulls to the right side, deceleration, loud noise like a tire blowout, vsc lights on dash come on. this has happened 4 times while driving the vehicle, no warning and you must pull over and turn the engine off and it will reset so you are able to start the vehicle to continue. very scary incidents!!!
Vehicle will engage anti lock braking system at speed and then no braking ability until vsc and traction control turn off. this can last up to 30 sec and vehicle becomes difficult to control.
The vsc trac, vsc off, brake light and abs light are all on on the dash. this is known problem with 1st generation toyota sequoia's. toyota issued a recall on the 03 models for this issue and provided a fix at their expense. the same issue occurs in other model years but there is no open recall for it. dealership wants approximately $2,000 to replace the skid control ecu.
The car makes a loud sound as if something was stuck underneath. at the same time it pulls to the right while severely vibrating. also at the same time the lights for tracking control and stability control turn on. after a few seconds the car seems to be in normal driving mode again except for the warning lights for the vsc off-light. the warning lights reset sometimes but that only leads to the same problem starting again.
My vehicle's vehicle stability control is engaging for no apparent reason while driving straight on a clear, clean, dry road. this has happened multiple times per month. both on highway and city street. (25mph-70mph) controlling the car can become hard to do. pretty loud grinding sound is heard when it is engaged. fear an accident may happen because the vehicle may pull due to the brakes engaging unexpectedly.
While driving at any speeds 65mph on freeway to around town at 30-40 mph the vsc trac and also vsc off light comes on and the car pulls to the right and acts like it is braking. this has happened multiple times at any speed. we have just missed cars from the pull to the right. very scary because it just happens no warning.
When driving on normal (safe and dry) road conditions, the vsa and trac control elements of the vehicle engaged and nearly caused me to crash. braking was severely inhibited (had to pump brakes to get them to work) and steering was jolted to the right/affected nearly causing an inadvertent lane change at highway speeds (65 miles per hour). was assessed by toyota and ruled to be a faulty steering column sensor and yaw rate sensor which is an astronomically expensive repair. my family is not safe in this vehicle due to the defect. please do something! this should be a recall!
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. the approximate failure mileage was 239,000.
