The National Highway Traffic Safety Administration is taking a second look at the electronic throttle systems in Toyota vehicles that are allegedly prone to sudden acceleration, says Transportation Secretary Ray LaHood, confirming news reports of the probe.
LaHood tells reporters the probe also will include complaints of sudden acceleration in vehicles made by other automakers. He says NHTSA will study whether electromagnetic interference from power lines could affect the performance of electronic throttle controls. He says the agency plans to meet with automakers and suppliers, independent experts and safety advocates.
NHTSA has previously examined a handful of Toyota vehicles blamed for sudden acceleration and found no defect. LaHood says the agency has no reason at this point to believe the systems pose a safety risk. Toyota says its testing has found no evidence of a problem that could cause unintended acceleration.
Safety experts suggest to Dow Jones Newswires that other electronic devices such as cell phones or Blackberries could interfere with a vehicle’s electronics. They note that airplane passengers aren’t allowed to use such devices during takeoff and landing for fear they might affect flight controls. Hospitals also restrict the use of electronic devices around medical equipment.
