The defect
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.
The 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.
