Updated Statement From Toyota Regarding Prius Brake Issue
February 04, 2010
TORRANCE, Calif., February 4, 2010 – Toyota is aware that NHTSA has opened a Preliminary Evaluation centered on owner complaints of a braking issue with the 2010 model year Prius. Toyota will cooperate fully with NHTSA’s investigation.
Some customers have complained of inconsistent brake feel during slow and steady application of brakes on rough or slick road surfaces when the anti-lock brake system (ABS) is activated in an effort to maintain tire traction. The system, in normal operation, engages and disengages rapidly (many times per second) as the control system senses and reacts to tire slippage. A running production change was introduced last month, improving the ABS system’s response time, as well as the system’s overall sensitivity to tire slippage.
This preliminary evaluation addresses owner complaints specific to the 2010 Prius. This condition is not related to either the floor mat entrapment recall or the sticky pedal recall currently in action.
Toyota will continue to evaluate the condition as it relates to owner complaints and will keep NHTSA informed of its progress.
