Representatives Henry Waxman and Bart Stupak have released a batch of documents this afternoon on the day before their committee hearing on the Toyota debacle. Their focus is largely on the issue of the possible role of electronic failures as a cause of sudden unintended acceleration cases. They criticized Toyota's response to the reports of electronic problems, and in their letter to transportaiton secretary Ray LaHood, say:
Our preliminary review of the documents and the information learned from the meetings with NHTSA officials raises two significant concerns. First, NHTSA appears to lack the expertise needed to evaluate defects in vehicle electronic controls. ... Second, NHTSA's response to complaints of sudden unintended acceleration in Toyota vehicles appears to have been seriously deficient.
