Investigators say that mechanical defects addressed in previous recalls are behind unintended acceleration and other safety issues. The Transportation Department, working with NASA engineers, found no electronic cause behind the problems. From AP:
"We enlisted the best and brightest engineers to study Toyota's electronics systems and the verdict is in. There is no electronic-based cause for unintended acceleration in Toyotas," Transportation Secretary Ray LaHood said in a statement.
LaHood said NASA engineers "rigorously examined" nine Toyotas driven by consumers who complained of unintended acceleration. NASA reviewed 280,000 lines of software code to look for flaws that could cause the acceleration. Investigators tested mechanical components in Toyotas that could lead to the problem and bombarded vehicles with electro-magnetic radiation to see whether it could make the electronics cause the cars to speed up.
This must be bad news for plaintiffs attorneys.
