Toyota Recalls 2010 Prius and Lexus HS250h for Brake Booster Defect

Toyota is recalling 87,060 model year 2010 Prius and Lexus HS250h vehicles because nitrogen gas from the brake booster pump assembly could leak into the brake fluid, potentially reducing hydraulic pressure and increasing the risk of a crash.

What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: The recall involves a structural vehicle defect in the braking system that could increase the risk of a crash, which aligns with the rubric criteria for a Severe (4) rating.

Plain-English summary

Toyota Motor Engineering & Manufacturing is recalling certain model year 2010 Prius vehicles manufactured between March 31, 2009, and October 9, 2009, and model year 2010 Lexus HS250h vehicles manufactured between June 19, 2009, and October 9, 2009. The recall covers a total of 87,060 vehicles.

The defect involves nitrogen gas from a component of the brake booster pump assembly leaking into the brake fluid. As the nitrogen is released into the brake fluid, the brake pedal may experience 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 began on August 7, 2013. Owners may contact Toyota at 1-800-331-4331 or the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or visit www.safercar.gov.
