Brake master cylinder failure.

While driving 65 mph on the expressway on January 12th, 2026 under cruise control, I tapped my brakes to slow down. My brake warning light came on, along with the ABS warning light, and the anti-swerve warning light. Cruise control no longer worked, and my brakes were noticeably hard to apply. I immediately had the vehicle computer checked and the issue is a leaking brake booster component, a faulty part known by Toyota to fail prematurely with this and other Prius models. No recall was issued…

Brakes went soft with little braking power. Traced the fault code to a faulty braking actuator; toyota says this is past the coverage date for the recall.

Warning lamps for ABS and others and the chiming dings came on while pulling away from the bank drive through and parking for a second. I shut the engine off and turned back on with no success.

My car had been making an electric noise every 15 seconds or so previously, at different times when parked, but I thought it was the hybrid engine. Now I think it was the brake pump trying to build up pressure due to a faulty, leaking …

While driving, suddenly all brake lights and warning lights went on, and brakes stopped working normally. It became difficult to brake (brake took a while to engage - had to press pedal to the floor). After diagnostics at the dealership it looks like the brake booster failed. Apparently Toyota knew about this issue as they did an extended warranty through a Customer Support Program, but unfortunately my issue occurred just past the expiration of that warranty. Since brakes are such a critical…

My 2013 Toyota Prius has a failed inverter/converter assembly, including the Intelligent Power Module (IPM). This component is critical for vehicle operation and designed to last the life of the car. Premature IPM shorting and inverter failure is a known defect acknowledged by Toyota through multiple recalls and service campaigns for other VINs with the same part number. My vehicle is giving codes P0A94 and P0A1A which are also listed in the recalls for other Prius models of similar age. My…
