One problem related to vsa warning light on has been reported for the 2006 Toyota Prius. The most recently reported issues are listed below.
2006 Toyota Prius. If it encounters bumpy road while turning and braking, then stability indicator will light up and brakes will stop working for about a second. It feels like the car is being driven on ice. It can be reproduced at will. Just bumpy road surface and turning/braking at the same time. Did not take it to a dealer to have it looked at it though. Learned to live with it.
