On july 12, 2017, I had backed up my 2017 toyota sequoia to a family member's house and then put the vehicle in park, but left it running. My three children remained inside the vehicle, seated and buckled. I exited the vehicle to walk to the back and put a box in the back and when I turned around, the vehicle had suddenly accelerated and was speeding away. The vehicle struck a small section of trees on the right side, which popped the front passenger door open. The vehicle then continued on until it ran through two fences and into the woods behind the neighbor's house, where it struck other trees and came to a stop. Upon catching up with the vehicle, the engine sounded as though it was still revving and was digging ruts into the ground. I opened the driver's door and found the gear shift just slightly out of park, which is not where I left it. I had to forcefully put it back into park by hitting it and then turned the key off. The motor wound down with a high pitched whining noise. I then unbuckled all three of my children (ages 11, 9, and 5) and got them out of the vehicle. The vehicle was heavily damaged in the front end and passenger side but no airbags deployed. There had been two other instances of trouble with this vehicle previously that toyota had stated they couldn't figure out what the problem was. The first was approx 2 weeks after purchase where it would lose power while driving and then suddenly get it back and surge. The second occurred in march 2018 and the vehicle would suddenly decelerate while on cruise control, even when there were no vehicles in front, and then suddenly reaccelerate. Neither time toyota could pinpoint a cause or fix for either but the vehicle suddenly worked after they checked it out. The edr report collected by toyota contained a large amount of incorrect data, such as the vehicle rolling over when it did not and other info.

Every time I drive my 2002 toyota sequoia within 10min on average the trac off/vsc warning sounds come on and the car violently shakes and the brakes seem to lock up. It usually starts at speeds from 25 to 40mph and sometimes even on the highway at 65mph, very dangerous and scary. I have to stop the vehicle and shut it off and restart it for the signs to go off and for the traction control to stop. This doesn't resolve the issue since it just starts again when I start the car back up and drive. Its gotten to the point where its not safe to drive the vehicle especially at long distances. The vehicles cruise control was off going straight on a smooth city streets or highway while in motion.

Toyota complaint, dangerous computer program, can cause death. Toyota programs the car computer to post a "maintenance required" sign to pop up on the dash. It has a "red triangle" also to get your attention. The sign stays on constantly until you take your vehicle into toyota to be serviced. This sign is very very distracting while driving because you can not see your speed that is hidden by the sign when you try to set your cruise control. I have run off the road several times while trying to adjust my cruise control and could not see it because of the maintenance sign. It is a very dangerous sign and toyota should remove it from the computer program. I hope someone files a class action law suit against toyota to force toyota to remove the maintenance reminder sign from the computer.

My vsc trac, trac off and check engine lights all came on yesterday. I was driving so I'm not sure if they all came on at the same time or not. The brake does not over ride cruise control on highway. So it will continue gas up even you use brake under cruise control mode. This is pretty disappointing since this problem has been seen all the way back to the first generation

My toyota sequoia sr5 is showing some lights in dashboard. First it was the vsc solid light coming on then off on it own, after some months, the airbag light came on then off then solid on, I went to the toyota dealer to get it check out, and they couldn`t find what is making the airbags light to come on. More recently, I started having a cruise control problem as well. The cruise control will sometimes work and also some other time refuse to work unless you turn the steering wheel over and over again and then it will sometimes kick -in. I have also noticed that the car will loose power while simply driving it, when it does so, the system will still be running but simply will get weak no matter how much gas you`re giving to the pedal. I hope to have this issues investigated since toyota doesn't really address them when I call them. Warm regards,
