I own a 2002 toyota sequoia 4x2. The vsc/trac lights came on after I had the battery replaced on dec. 20, 2006. My toyota specialist could not figure out what the problem was but said that the sequoia's seem to have multiple problems relating to brakes and computers. I took it to the dealer on jan. 8, 2007 and they said it has been a common/ongoing problem. Toyota has not recalled this problem though. They could fix the ecc (electrical computer component) at the cost of $1,600. I said no thanks.
2002 Toyota Sequoia acceleration complaints
Page 6 of 6: complaints 131 to 135 of 135, newest first, as owners wrote them.
During the past few months 'vsc trac" ,"vsc off","slip or skid","ABS",lights is going off while driving at low speeds like making turns and trying to accelerate from stop, even though the pavement is dry this happens every time ever since, brakes automatically apply causing the car to cut off or prevent the car from accelerating thus results in not able to control the car, there were instances that making turns is very dangerous due to the fact that the vehicle behind you can hit you due to the fact that failure to accelerate when needed because the ABS/vsc systems override you from accelerating by pressing the gas pedal, this seems to be a common complaint in online forums like edmunds.com tudrasolutions.com, and there was a discussion in there that someone's car with the vsc failure caught on fire, pls investigate.
Trac off and vsc trac lights intermittently turn on, sometimes when vehicle is in motion and sometimes when vehicle is in idle. While in motion, if trac off and vsc trac lights turn on, beeping occurs, grinding or "whirring" noises are audible and brakes cannot be depressed. Since the first incident, I've changed the rear differential oil and found small metal bits in the oil.
Abs vsc trac control system lights come regularly. Before lights come on, systems prevent acceleration for several seconds resulting in potentially dangerous inability to navigate the car. This continually happens.
I have a 2002 toyota sequoia sr5 4x4 and my ABS, brake, vcs, trac lights on my dashboard remain on. I have researched this problem on www.edmunds.com and on www.tundrasolutions.com and appears to a common problem for owners of 2000-2003 sequoia models. My 2002 has had several recalls that dealt with brakes and suspension. It appears that when the brake recall was conducted they did not upgrade other parts of the braking system including computer sensors/modules. I believe this is a safety related defect to these model years that should be covered by toyota. What I read on the above websites is that toyota has charged owners thousands of dollars to repair this defect when it should be a free repair.
