One problem related to anti-lock brakes fail has been reported for the 2007 Toyota Prius. The most recently reported issues are listed below.
Toyota Prius 2007 - antilock brake failure hitting potholes, man hole covers, crossing train tracks, going the speed limit down hills, rain & snow are the worst. Every time car is taken in to dealer for servicing, we inform them of the brakes. They ensured us that nothing was wrong with them and there was nothing to worry about. We contacted our primary dealer who has done most of the services for the car, they conveniently no longer have service records for my vehicle prior to August 2009. The most recent incident that sent us complaining to the dealer was in October 2009, when returning home from work and the brakes needed to be applied in order to avoid hitting a deer, the brakes did absolutely nothing. The car continued to move and narrowly missed hitting the deer. This was reported to Toyota of york in pennsylvania. The primary dealership that has provided our services is riverhead Toyota in new york. The recent snowfall in pennsylvania has essentially made my car useless, it cannot handle the snowy roads without sliding all over the place, and we no longer trust the brake system in the event we need them. No physical injuries have occurred as a result of the brakes on our particular car, however emotionally, we are worried about placing ourselves in any potential situations where an accident could occur.
