Toyota installed known faulty brake booster and master cylinder systems in Prius C models manufactured 2012-2014. Knowing these systems would fail, but not wanting to pay for their mistake, they created a basically secret ‘extended warranty program’ for owners to get their brake booster replaced ONLY IF for a specific 2 year time frame their brakes failed with a certain DTC code. Knowing that many prius owners would not actually receive the notification nor had driven their vehicle enough miles for the braking system to fail, they got away without having to correct their issue. The brakes literally just fail and stop working in the middle of the highway, causing extreme safety concerns and accidents with no responsibility from Toyota.
