Chuck Grassley wants NHTSA to take another look at Toyota’s unintended acceleration

Article by Christian Andrei, on July 14, 2012

The unintended acceleration controversy facing Toyota Motor Corp. may not have ended yet as Iowa Republican U.S. Sen. Chuck Grassley wants to take another look at this issue. Sen. Grassley sent a letter to the National Highway Traffic Safety Administration last Thursday to ask about the phenomenon of "tin whiskers," specifically crystalline structures of tin, that may theoretically cause the vehicles to take off all of a sudden, according to a report.

Sen. Grassley, a ranking member of the Senate Judiciary Committee, cited documentation given by whistle-blowers about the probe by NHTSA and NASA into the Toyota issue, which led to the recall of Toyota units throughout the world.

According to the report, just because no proof was found that unintended accelerations stemmed from electronic throttle-control systems doesn’t mean that it couldn’t have been the reason. The agency said that it has already gotten the letter and that it was being reviewed. Grassley requested the NHTSA to reply by July 26.

Grassley had written that the data received by its officer brings to light worries that the NHTSA probe was “too narrow.” He said that there are unanswered issues left about what had caused unintended acceleration just as NHTSA demands for brake-override throttles to be a requirement.

NASA and the NHTSA conducted an investigation for 10 months and concluded that the Toyota models didn’t have any electronic defect. The agencies put the blame on stuck pedals or those that got caught on the floor mats.
