Traction control problems

8707 Views 16 Replies 9 Participants Last post by  fibber2
Driving under normal conditions, typically around a curve our traction control will engage. Car immediately slows, dashboard warning beeps/lights for a few seconds and then back to normal. My mechanic and Toyota dealer could not replicate it during test drives to get error code. Any advice on how to diagnose and what it could be?

Hi Fiegerph,

I am also curious to know if you had any further issues. I am having the same exact issue as you described. Usually VSC and TRAC control activate on sharper right curves at 25-35mph. I took it in to my mechanic and he stated that the rack and pinion needs replacing. Any thoughts from anyone? My Sienna is an 07' just hovering under 190,000.
