“I own a 2009 Toyota Prius and when the vehicle encounters a pot hole or any rough road service, it jumps ahead and there is a delay when I attempt to brake. On the dashboard the icy roadway indicataor appears at these times. This siituation has been ongoing since I purchased the vehicle in april 2009”

“The problem with the Prius is the enhanced vsc, not the brakes! I have been reading about the braking problem in the Toyota Prius and they all seem to occur under rough or slippery driving conditions. I own a 2009 Prius and the same thing happens but it seems to be a problem with the enhanced vehicle stability control (vsc). Please look into the enhanced vsc for the problem because I don't think it's the brakes.”

“As I was driving my 2009 Toyota Prius on the service road of I-30 in dallas around 25 MPH after previously taking off from a red light, my vehicle's warning lights all turned on and started to beep and I could not brake or really steer. My vehicle...I almost hit the vehicle in front of me. Somehow I was able to turn right into a parking lot and somehow press on the brakes strong in enough to make the car stop. I feared for safety and the safety others as well. …”

“Every day I encounter a large pot hole on my way to work. It is about 20 feet from a stop sign, so at this point I am already driving slow and braking. However, when the one wheel dips into the hole, the yellow traction system light comes on, and I feel what could be a slight loss in braking, as if the car is coasting for a split second (versus braking/slowing) or perhaps accelerating forward. The car/system recovers as soon as all wheels pass the pothole. …”
