What Happened
Your vehicle's brake booster pump assembly might have a small leak that could let nitrogen gas into the brake fluid. This is a safety issue that affects the Prius and Lexus HS250h models made in a certain time period.
Risk if Unfixed
If the leak happens, your brake pedal might feel spongy, and you might need to push it further down to stop the car. This could make it harder to stop in an emergency situation and increase the risk of a crash.
Free Fix
Don't worry, this is a free fix! Toyota will notify you and their dealers will replace the brake booster pump assembly at no cost to you. You'll receive a call or letter with the details and a schedule for the repair.

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.
