Toyota Study Finds No Electronic Flaw Behind Sudden Acceleration Hazard

Toyota’s recent problems with unintended acceleration, which have led to millions of auto recalls and are linked to dozens of deaths in the U.S., are not the product of an electronic defect, according to a widely anticipated new report.

The report, prepared by NASA and released Tuesday by the National Highway Traffic Safety Administration, said that mechanical safety defects identified more than a year ago  “remain the only known causes for these kinds of unsafe, unintended acceleration incidents.” As the Los Angeles Times reports, those mechanical problems include sticky accelerator pedals and pedals trapped by floor mats.

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.”

Even so, NTSA said it is considering steps to deal with sudden acceleration. The measures include proposing rules by the end of the year to require brake override systems, standardized keyless ignition systems and accident data recorders in all passenger vehicles. The agency also is proposing to launch research on the reliability and security of electronic control systems and to study the design and placement of accelerator pedals.

In its 10-month study for transportation officials, NASA, the nation’s space agency, examined the electronics, software, wiring and in-house processes employed by Toyota.

Before the report’s release, officials with the Japanese car giant said that they looked “forward to reviewing the NASA and NHTSA report regarding our electronic throttle control system,” the Times reported.

A more comprehensive evaluation of vehicle electronics and sudden acceleration is expected to be issued by the National Research Council in July.

Once thought of as one of the world’s most reliable car makers, Toyota’s reputation has been tarnished, and its sales hurt, over the last 18 months.  More than 12 million vehicles have been recalled in the U.S. since late 2009 as a result of reports of unintended acceleration and other problems.

In December, Toyota agreed to pay more than $32.4 million in fines for failing to inform U.S. regulators promptly about vehicle defects. That followed a $16.4-million fine in April for delaying the recall of vehicles with gas pedals that could become stuck.
