Toyota to US Senate: Electronic Engine Controls Safe VOA News 02 March 2010 A Toyota employee installs an accelerator into a new Camry in Georgetown, Kentucky, 18 Feb 2009 Photo: AP A Toyota employee installs an accelerator into a new Camry in Georgetown, Kentucky, 18 Feb 2009 Toyota's top engineer says the automaker is confident its electronic engine controls are not causing cars to accelerate suddenly. Toyota chief engineer Takeshi Uchiyamada told U.S. lawmakers Tuesday that electronic engine controls are designed to ensure "absolute reliability" and that intense testing has failed to turn up any flaws. The hearing before the Senate's Commerce, Science and Transportation Committee is the third congressional hearing on the auto giant's safety problems in the past seven days. The automaker has recalled more than 8 million vehicles for problems with unintended acceleration. Some experts and lawmakers believe a faulty electronic system is to blame. Senate committee Chairman John Rockefeller opened the hearing, charging that safety concerns at Toyota "took a back seat" to profits. The U.S. Department of Transportation said Tuesday it is now investigating 52 deaths over the past decade for possible links to unintended acceleration in Toyota vehicles. During the hearing, Toyota Executive Vice President Shinichi Sasaki said the auto giant is, in his words, "fundamentally overhauling" its quality assurance processes. Yoshimi Inaba, the president of Toyota's North American arm, said former U.S. Transportation Secretary Rodney Slater has been picked to head an independent quality control review panel. Last week, Toyota President Akio Toyoda apologized before a U.S. House committee for not doing enough to fix safety problems that prompted a massive recall. A poll by the Gallup Organization and USA Today released Tuesday finds almost one-third of Americans now think Toyota-made vehicles are unsafe to drive. Almost one out of every five people polled also said they would no longer consider buying a Toyota. Still, a majority of those polled, 53 percent, said they would consider buying a Toyota. Also Tuesday, Toyota said it is repairing nearly one million vehicles in the U.S. and Japan for potentially leaky oil hoses, but the company says it is not a recall because the problem did not affect safety. Toyota said in an email statement that the faulty hoses can cause engine noise and light up the oil pressure light on dashboards.
