| Traction Control System problems |
On my 2005 Toyota xle limited, the traction control system engaged on its own while driving about 50 mph on a flat road in dry conditions, as a result the brakes engaged on its own and the car shook profusely for a couple of seconds. I had to hold onto the steering wheel to maintain control and avoid going into the neighboring lane. My 2005 Toyota Sienna has 84,000 miles on it. There have been two other incidences when the traction control engaged but the brakes did not. I have only owned the car for 1 week and I am communicating with Toyota but I they have yet to organize a recall for this very dangerous problem. I plan to drive to canada in this car so I hope we can find a solution.
2005 Sienna was driven to a parking garage and parked for two hours. Upon returning to the Sienna and starting the engine, three lights came on; check engine, vsc, and trac off. Drove vehicle home (150 miles), the 3 lights remained on as well as loss of cruise control and an intermittent compass display. Took vehicle in for inspection at a local Toyota dealer and was told the skid control unit ecu needed to be replaced. I found out there are other complaints and a technical service bulletin on the 2005 Sienna vehicle stability control (also called electronic stability control) system that has caused injuries. Even more remarkable, my 2005 Sienna has only 62k miles and in that time there has been 2 other incidences with the same symptoms. Why has there not been a recall if there are already injuries in the database??.
