When the vsc light or the traction light comes on the alarm sounds and the the van brakes for me! it can be up hill or down hills, between 30mph-70mph, left or right curves. Thas happend on dry pavement, it is dangerous because the van braking suddenly for me and dont let me accelerate.
Slid warning light, vsc comes on randomly. Has been happening beginning at 110k miles. Taken to dealership and reported durning normal service. I worked at a Toyota dealer. Front end suspension has been rebuilt. Cv shafts replaced. Rock solid. Dangerous as the vsc system engages and the slid light comes on, tire speed control engages, happens in a normal 70mph easy turn on the expressway. No codes stored. Only warning lights and vsc actions engaging for no reason.
The main spring that supported the entire front of the car just collapsed as I was about to park my car. Thank god it did not happen while I was on the highway. Although there was a safety/service bulletin listed by Toyota on this part they would not cover the replacement cost of almost $1500.
