Senator Pushes NHTSA to Revisit Toyota Accelerator Issue
By Christina Rogers, Automotive News
U.S. Sen. Chuck Grassley is pressing the National Highway Traffic Safety Administration to take another look at questions about what caused Toyota Motor Corp. cars to unintentionally accelerate.
In a letter to the regulatory agency on July 12, the Iowa Republican and ranking member of the Senate Judiciary Committee asked NHTSA to examine the phenomenon of "tin whiskers"-- crystalline structures of tin -- that could theoretically cause the vehicles to suddenly take off, according to a report on CNN.com.
Grassley cited documentation provided by whistle-blowers about the investigation by NHTSA and NASA into the Toyota problem, which resulted in the recall of millions of vehicles worldwide.
One report stated: "Because proof that the (electronic throttle-control systems) caused the reported (unintended accelerations) was not found does not mean it could not occur."
NHTSA confirmed it had received the letter and was reviewing it, but didn't have an immediate comment.
Grassley asked for NHTSA to provide his office with a response by July 26.
The information provided to his office raises concerns about whether regulators' investigation was "too narrow" in scope, Grassley wrote.
He added that it also leaves unanswered questions about the causes of unintended acceleration, just as NHTSA moves to require brake-override throttles in response.
A 10-month investigation by NASA and NHTSA into the matter found no electronic defect in Toyota models. The agencies blamed the incidents on pedals that got stuck or caught under floor mats.
But Grassley, in his letter, noted that the NASA report also stated: "Because proof that the (electronic throttle-control systems) caused the reported (unintended accelerations) was not found does not mean it could not occur."
NASA also reported finding tin whiskers in its analysis of the brake assembly, noting that they could cause a short circuit between the pedal signal and outputs. This condition could theoretically caused a car to unintentionally accelerate.
CNN.com quoted a Toyota spokesman who said that "so-called 'tin whiskers' are not a new phenomenon and do not represent a mysterious or undetectable problem in a vehicle's electronics."
A Toyota spokesman could not be immediately reached for further comment Friday morning.
In its review, NASA concluded that there were 9,698 identified unintentionally acceleration complaints from 2000 to 2010, but NHTSA concedes the number could be much higher because not all incidents are reported.
Toyota ended up paying fines of $48.8 million for failing to order the recall in a timely manner.
More aggressive policies
Since the Toyota recall, regulators have become more aggressive about addressing the issue. NHTSA has been exploring a brake-throttle override system mandate since 2010.
In April, the regulatory agency proposed a requirement that all light vehicles have an override mechanism that enables drivers to stop a car or truck, if the accelerator pedal gets stuck.
NHTSA didn't didn't offer an estimate on how much it would cost manufacturers to add the technology, only saying it could be done "without significant difficulty or cost."

I've questioned the NHTSA results ever since they were published. That being while some of the incidents were the result of the floor mats and sticky pedals, the majority were supposedly driver error. That is, pushing the accellerator instead of the brake pedal.
Let's call this phenomenon, incompetence.
Are we then to believe that incompetent drivers ONLY drive Toyotas?
If it were truely driver error, other manufacturers would be experiencing similar situations at about the same percentage rate.
The public perception of an Ameican car in America is out of date, the public perception of a Japanese can in America is out of touch with reality.
Thank you Sen. Chuck Grassley for not yielding and taking Toyota to task for a problem that had at least 10 THOUSAND incidents and took 10 YEARS for them to address.
Ford, GM, VW and other companies test parts and cars long after a sale so they find problems BEFORE there is a NHTSA complaint. Those manufacturers also use a black box that investigators can easily read-not one that has to be taken back to Japan and analyzed in secret.
People died because of this issue, and I would like to see more of a change in how Toyota does business and takes care of their quality issues. When they start initiating major recalls on their own, without the NHTSAs intervention, AND make the even POSSIBLE in the US by using a black box that can be read so the info is transparent; then I can respect how they deal with their problems.
