Service brakes
Problem: 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.
Risk: 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.
Fix: 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.
