Q&A for 2010 Model Year Prius and HS250h Vehicle Brake Feel
Q1: What is the condition? A1: In certain 2010 model year Prius vehicles, a small number of customers have reported experiencing an inconsistent brake feel during slow and steady application of the brakes on rough or slick road surfaces when the anti-lock brake system (ABS) is activated in an effort to maintain tire traction. Q2: What is the cause of the condition? A2: This condition is as a result of braking system switching between regenerative and hydraulic braking. The system, in normal operation, engages and disengages rapidly (many times per second) as the control system senses and reacts to tire slippage.

In the event that a driver experiences an accelerator pedal that sticks in a partial open throttle position or returns slowly to idle position, the vehicle can be controlled with firm and steady application of the brakes. The brakes should not be pumped repeatedly as it could deplete vacuum assist, requiring stronger brake pedal pressure
