Toyota recall: NASA says that the 'sticky' accelerator pedals that killed at least 50 people and led to a recall of nearly 8 million cars last year were not the result of faulty electronics.
In March 2010, at the time of the recall, Toyota was unsure of the cause behind a spate of cars that would speed up without the driver's help. The Toyota problem was linked to at least 50 reported fatalities, according to the National Highway Traffic Safety Administration (NHTSA).
Eventually, the NHTSA identified two mechanical defects behind the malfunction: "sticking" accelerator pedals and a design flaw that caused the pedals to become trapped by floor mats.
However, the NHTSA asked NASA engineers with expertise in electronic and software systems to look into consumer claims that electronic systems may have played a role.
