Biller worked four years for Toyota, handling product liability lawsuits from consumers about safety defects. Now he's blowing the whistle. He and Toyota are suing each other and he's asking a federal judge to make public documents he says will prove Toyota regularly hid evidence of safety defects.
"It was a culture of hypocrisy and deception," said Biller.
Toyota denies Biller's charges and says he is just a disgruntled former employee who is angry he lost his job.
In a statement, Toyota said Biller had left the company in 2007, and would not have any knowledge about current matters.
"Mr. Biller continues to make inaccurate and misleading allegations about Toyota's conduct that we strongly dispute and will continue to fight against vigorously," said the statement.
Toyota also said Biller did not handle unwanted acceleration cases while he worked at the company.
Biller disputes that, saying he worked as the managing attorney for Toyota on a sudden acceleration case involving Lexuses that was filed in 2005.
