General Motors (GM) authorized faulty ignition switches for its vehicles in 2002 despite the parts not appearing to meet the car-maker's requirements, Delphi Automotive has told U.S. congressional investigators.
The House Energy & Commerce Committee released the information yesterday, two days before GM CEO Mary Barra is due to testify before the panel about the switches, which have been linked with at least 13 deaths.
The committee also said that the National Highway Traffic Safety Administration twice decided not to open formal probes into the cars.
Meanwhile, GM has recalled 490,000 trucks and 172,000 compact cars, due to the possibility of oil leaks and fires because of a loose fitting for an oil-cooler line. GM is aware of three fires but no injuries. The company has now recalled 4.8M vehicles this year.
