 I owned the 2002 sequoia and had 92k miles on it. In Mar 2016 my wife drove it at 50-55 mph on a high traffic state highway and the trac control and VSC lights came on and the vehicle speed reduced to about 10 mph in a few seconds. She almost got heat by the other cars behind her, but she was able to move to the right and exit the highway safely. I did the search and found out that this model has had safety issue on trac control/VSC, but toyota only recalled on 2003. I took the car to the toyota dealer and he said it just the O2 sensors failure. I looked over his mechanic report and saw another sensor, accelerator paddle control sensor also a problem. However he did not put that on the report to me/customer. He said that it will cost 1300 to repair and he is not recommended to drive it in this condition. I took the car back and sold it few days later for "better safe than sorry"
