Several owners of the 2010 Prius have complained about inconsistent brake feel when the vehicle is driven over potholes, bumps or slippery road surfaces. Toyota says that there were design problems with the anti-lock braking system of the Prius.

 

"Toyota Motor Corporation spokeswoman Ririko Takeuchi said that Toyota found out there were design problems and corrected the design for Prius models sold since late January. It was still investigating how to inform people who had bought them earlier though."

 

This is SEPARATE from the issue that Steve Wozniak, Co-Founder of Apple, had pointed out in his 2010 Prius. Wozniak said his Prius has a software-related acceleration problem that only happens when he uses the cruise control. His Prius can "unintentionally accelerate to as much as 97 miles per hour when he uses cruise control to increase his speed."
