I wondered if you are aware of some major issues with Toyota's Safety Sense (TSS) system. TSS controls the pre-collision system, collision mitigation system, lane departure system, automatic dipping lights. In cold and wet weather, at night, in fog and seemingly at random, the car's computer disconnects the system - accompanied by a bright yellow flashing light (VERY distracting at night and a safety issue in its own right) and a complete info panel warning. Toyota contends that this shows the system is operating correctly. Nothing in Toyota's publicity states that TSS is a "sometimes on - sometimes off" system and so it's not at all unreasonable for owners to believe they would always have this additional safety system available.
