    Ghostbusters: NASA tests find no electronic problems with Toyotas

    Consumer Reports News: February 10, 2011 05:52 PM

    Just before last Halloween, we wrote about "ghosts in the machine"—appliances that seemed to have a mind of their own. Cars appeared to be haunted last year, too. After Toyota recalled 8 million vehicles in the United States for sudden unintended acceleration problems related to either the floor mats or sticky accelerator pedals, some owners complained that their vehicles still experienced the problem—even after they were fixed.

    An electronic ghost, perhaps? Not according to a 10-month study conducted by NASA at the request of the National Highway Traffic Safety Administration (NHTSA) to determine if electromagnetic interference or software glitches were at least partially responsible for the vehicles speeding out of control.

    Department of Transportation Secretary Ray LaHood announced this week that NASA engineers found no evidence of electronic-based causes for unintended acceleration in Toyotas.

    "As we stated last year, there are only two real-world causes of high-speed unintended acceleration in Toyotas," said LaHood. "First, some Toyota floor mats entrapped drivers' gas pedals while their vehicles were in motion. Second, so-called 'sticky pedals' made some Toyota accelerators too slow to release."

    As an evidence-based organization, the fact that NASA did not discover an acceleration-causing ghost gives us confidence in our recommendations for Toyota vehicles.
