GM’s Suspended Engineers Made Fateful Calls on Faulty Cobalt – Bloomberg
By 2012, GM knew a switch flaw was causing some Cobalts and other models to stall and prevent airbags from deploying, according to Lance Cooper, the Georgia lawyer who deposed DeGiorgio and several other GM engineers as part of the wrongful death suit against the automaker. Yet GM’s inhouse investigators, who had been looking into the flaw for two years, couldn’t figure out why it wasn’t showing up in later models, Cooper said.
In part, that was because DeGiorgio didn’t tell the investigators he had ordered the redesigned part without assigning it a new number, Cooper said last week in an interview at his office in Marietta.
