According to the plaintiffs, the NASA study only reviewed 280,000 out of the 8 million lines of code in Toyota's electronic systems. They also pointed to so-called Tin Whiskers as a potential cause, citing their role in the failure of three commercial satellites.
The NASA report, which was revealed on February 8, concluded that the accelerator-related issues encountered by Toyota drivers were caused by sticking pedals, floor-mat jams, or driver error. The report had focused on just nine vehicles over ten months, and on those it could find no defects.
The first of several so-called "bellwether" cases dealing with the acceleration issue will be set for trial in 2013, and a U.S. District Court judge recently posted that one of the first two trials would involve a Camry and Toyota's electronic throttle system.
