Toyota Prius Plug-In brake system failure after ABS parts replacement on Toyota Prius Plug-In

Some Toyota Prius Plug-In owners report experiencing brake system failures after replacing ABS parts, which can lead to serious safety concerns on the road. Issues such as brake actuator failure can render the ABS and brake booster systems ineffective, making traction control useless and increasing the risk of severe accidents. Additionally, some owners have faced costly repairs, with quotes for ABS actuator replacements exceeding $5000, particularly when using new OEM parts. Warning signs like the "Check hybrid system" light, red BRAKE light, and persistent illumination of the ABS and VSC lights may indicate ongoing brake system problems, including reduced braking force. Toyota has issued goodwill Technical Service Bulletins (TSBs) and warranty extensions for certain models, suggesting that owners check with their dealership for potential support. Furthermore, when replacing ABS components, ensuring the correct parts are sourced is crucial to avoid compatibility issues across different Prius generations. It is advisable for owners experiencing these issues to consult with a certified technician or dealership for accurate diagnosis and appropriate solutions.
