Car Slowed Down On Its Own Problems of Toyota Sequoia

While driving our 01 Sequoia sr5 with only 85,000 miles on side streets and highways at speeds ranging from 5mph to 70 mph, the SUV's braking system suddenly engages for no reason while the veh. Is in motion. The vsc, check engine lights come on along with the alerting sound. When the brakes engage, the veh. Veers to the right, the steering wheel vibrates and the veh. Goes into a skid due to the brakes being suddenly engaged. The veh. Also decelerates suddenly as if it has lost power. This is dangerous for other drivers who can't tell if you are braking because there are no brake lights to be seen to prevent a collision. Thankfully we have been able to react defensively and avoid collisions with other veh. 's. And roadside objects. We have seen several suggestions as to the fix for this problem like the yaw rate sensor being replaced. The cost of the part is $568. 00 without the install cost. This problem is a safety issue and if it occurs at the wrong time, a preventable tragedy is going to occur. I have seen well over 50 complaints on this from other owners and a closed NHTSA investigation on this exact issue. They recalled the 2003 Sequoia for the same issue. Toyota needs to fix this in all model years before a life is lost. . Read more...

While I was driving at an approximate speed of 40 mph, I noticed my brake, trac off, vsc trac, engine light all came on at once. I noticed that braking was not as responsive (increased braking distance; abs doesn't seem to be engaging) and when speeding to over 50 mph, the vehicle feels as if it is slowing itself down. It is currently an expected heavy rainfall season where I am and having the vehicle in this state is very dangerous especially when the brakes are not working effectively or when it starts to slow itself down suddenly. After shutting the vehicle down and restarting it after about 2 hours, the lights mentioned are still illuminated except the brake light. After reading all the other similar complaints, I am surprised Toyota is not paying for all aspects of this defect associated with the vehicle and not driver misuse.

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 active and the shop indicated that nothing could be done unless the codes were active again. Research indicates the 2003-04 had skid control computer recall, reflashing/reprogramming the computer but only a TSB was issued on the 2005 model year. After the third incident, the most severe, we went to a Toyota dealer. They confirmed the recall & the TSB. In discussions with the service advisor's and technicians, they both reported that they have had numerous 2005 models with the same issue. The dealer informed us that the skid control computer will need to be replaced at a total cost of $1100. However, numerous posts on online blogs & forums indicate the problem persists even after the skid control computer was replaced. We are lucky that this event did not result is an accident as we were in traffic and vehicles behind us would not expect our vehicle to suddenly brake causing them crash into us at full speed. This is a severe known safety issue and Toyota should issue a recall.

Since end of June 2010, I had to have my 2002 Toyota Sequoia towed because it had started to veer off and the wheel became stiff and I couldn't control the steering. The vsc lights came on as well as the "squiggly car" light. I was scared to drive it again as I was 100 miles away from home, so I had it towed. I had taken it to the Toyota dealership and they diagnosed the bearings but couldn't diagnose the failure I had felt as far as the vsc incident. They charged me for inspection but said they didn't know exactly what was wrong and sent me home with the car. I experienced this for a few days and finally took it to an independent auto repair. They did a zero recalibrating and saw there was issues on the computer coming up but couldn't also exactly pinpoint what was wrong. It took a week before I got it back as it didn't reoccur with them. The following day as I drove it, the vsc lights and squiggly car light came on again. Every time I made a turn it seemed it jumped and it wouldn't gain acceleration quickly when I pressed on the gas. Plus it made this loud noise as if something was rubbing and it would slow down , then after a few seconds, regain speed. I took it in again and they replaced the yaw sensor. The following day, again taking the streets it seemed that everytime I stopped and pressed again it shifted something as I felt it under the pedals, the vsc lights would turn on but then turn off and then finally regain speed. Each and every time I was stopped at a light and then pressed on the gas, it did this. I finally looked up a recall that one technician told me about and noticed the 2003 recall for traction control system. However Toyota will not help since my car is 2002, hence why I'm complaining about it now. I believe the exact thing is what is happening to my car. I've had it swerve on the freeway when the vsc light came on and am afraid to drive it on the freeway for fear of it slowing down unexpectedly.

The contact owns 2001 Toyota Sequoia. While driving 70 mph, the vehicle slowed down rapidly without warning while he depressed the accelerator pedal. The dealer was unable to duplicate the failure. The current mileage was 100,000 and failure mileage was 5,000. The VIN was unavailable.
