NASA report on Toyota issues

The LA Times wrote:

Transportation Secretary Ray LaHood said: "We enlisted the best and brightest engineers to study Toyota's electronics system, and the verdict is in. There is no electronic-based cause for unintended, high-speed acceleration in Toyotas."

For the study, a team of NASA engineers evaluated the electronic circuitry in Toyota vehicles and analyzed more than 280,000 lines of software code.

"NASA found no evidence that a malfunction in electronics caused large, unintended accelerations," said Michael Kirsh, principal engineer at the NASA Engineering and Safety Center.

NASA's study "confirmed that there is a theoretical possibility that two faults could combine under very specific conditions" to affect the electronic control systems to create an unintended acceleration. But the team "did not find any evidence that this had occurred in the real world or that there are failure mechanisms that would combine to make this occurrence likely."

From MarketWatch: During the news conference explaining their [NASA's] conclusion, one investigator emphatically stated he was “incredibly confident” that electronics played no part in the problem.
