Brake booster failed. ABS lights on. Brake light on. Traction control light on. Was sitting at stop with foot gently on brake when lights turned on.

I took it to a Toyota dealership, and they found that the brake booster and pump had failed. I looked online and saw that many other Prius owners had the same issue, so it doesn’t seem like an isolated case.
