The brake booster pump in your Prius is a crucial part that helps you stop your vehicle. It's possible that nitrogen gas is leaking into the brake fluid, which could cause problems.
Risk if Unfixed
If this happens, your brake pedal might feel soft or spongy. Under certain conditions, this could make it harder to stop your vehicle, increasing the risk of a crash.
Free Fix
Your Toyota dealer will replace the brake booster pump assembly with a new one, and this repair is completely free. You should schedule the repair as soon as you get the recall notice.

Original — What Happened
Toyota is recalling certain model year 2010 Prius vehicles manufactured March 31, 2009, through October 9, 2009; and model year 2010 Lexus HS250h vehicles manufactured June 19, 2009, through October 9, 2009. Nitrogen gas from a component of the brake booster pump assembly could leak into the brake fluid.
Original — Risk if Unfixed
As nitrogen is released into the brake fluid, the brake pedal may have reduced hydraulic pressure. Under certain circumstances, this condition could affect stopping distance and increase the risk of a crash.
Original — Remedy
Toyota will notify owners, and dealers will replace the affected brake booster pump assemblies. The recall began on August 7, 2013. Owners may contact Toyota at 1-800-331-4331.

The anti-lock braking system (ABS) control unit in your car helps you stop smoothly on slippery or rough roads. In some 2010 Prius and Lexus HS250h models, this unit can send mixed signals to the brakes, making it harder to stop.
Risk if Unfixed
If the ABS control unit isn't working correctly, you might need to press the brake pedal harder than usual to stop, which could increase the distance it takes to stop. This might lead to a higher risk of a crash, especially on slippery or uneven roads.
Free Fix
Your authorized Toyota or Lexus dealer will reprogram the ABS control unit to ensure it works as expected. This repair is free, and you should schedule it as soon as possible.
