As many as 20,000 Toyota Prius owners have had electric power system failures after the company recalled their vehicles in 2014 and attempted to remedy a safety defect by modifying software.

The disclosure was made by a Toyota executive during testimony in a high-stakes, two-month-long civil trial that had closing arguments Monday in Orange County Superior Court in Santa Ana.
The jury of seven men and five women is scheduled to begin deliberating on Tuesday.

The case was brought against Toyota by Roger Hogan, one of the largest Toyota dealers in Southern California, who alleges that after he began sounding alarms about the problem Toyota retaliated against his dealerships in San Juan Capistrano and Claremont.
