The National Highway Traffic Safety Administration, with the aid of NASA engineers, concluded that the electronics systems found in Toyota’s vehicles was, in all likelihood, not the cause of unintended acceleration. In 2009 and 2010, the Japanese car manufacturer recalled nearly 8 million cars after drivers began reporting sudden and unprovoked acceleration from their vehicles.
“Our conclusion- that Toyota’s problems were mechanical, not electrical – comes after one of the most exhaustive, thorough, and intensive research efforts ever undertaken,” said Department of Transportation Secretary, Ray LaHood.
The report determined that two mechanical defects in the accelerator pedal and floor mats are to blame. “Both problems had been identified before the NASA investigators began their work.” NASA was given unrestricted access to over 200,000 lines of code used in Toyota’s vehicles; its examination of said code lasted over 10 months.
Toyota says it’s confident that the issue is now resolved and that its cars are amongst the safest on the road.
