Apple co-founder The Woz says his Prius has acceleration flaw.

Toyota is now in a bigger hole than before because of their lackluster response to the pedal problem. Having Woz come out and complain about the Prius is going to make things worse on another front because he has the cache with that segment of the driving population to make them worried.

Count Apple Inc. co-founder Steve Wozniak among Toyota Motor Corp. car owners who say their vehicles accelerate unintentionally.

Wozniak’s 2010 Toyota Prius can unintentionally accelerate to as much as 97 miles (156 kilometers) per hour when he uses cruise control to increase his speed, he said in an interview yesterday. Toyota and the U.S. National Highway Traffic Safety Administration haven’t responded to his complaints in the past two months on what may be a software-related glitch, he said.

“It’s scary when it happens,” Wozniak, 59, said from San Jose, California. “I’ve had trouble getting both the government safety agency and getting Toyota to listen to me.”
