The Brakes May Not Perform as Expected
Brakes, June 5, 2013
RepairPal Expert Overview
Our Quick Take:
Reduced braking performance may be experienced due to a brake booster system issue.
What Should You Do?
Toyota will begin notifying owners of the affected vehicles during July, 2013. If you notice problems with the braking system, or you don't receive notification and you feel you should have, please contact your dealer for further instruction. They may ask for your vehicle identification number (VIN), so please have it handy when you call.
The brake booster pump contains a compartment filled with nitrogen gas. This nitrogen gas can leak into the brake fluid causing reduced hydraulic pressure during application of the brakes. Reduced braking efficiency can increase the risk of a crash. Dealers will replace the brake booster pump assembly as necessary to correct this concern.

Potential Number of Units Affected:
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.
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.
Toyota will notify owners, and dealers will replace the affected brake booster pump assemblies. The recall is expected to begin in late July 2013. Owners may contact Toyota at 1-800-331-4331.
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
