Members of the Senate Commerce Committee's consumer protection panel has raised the possibility of a criminal prosecution and vowed to conduct more hearings over General Motors’ handling of its faulty ignition switch recall. The new hearings may invite former GM officials in charge during the years that vehicles with the defective ignition switch were not recalled – until February 2014.
Sen. Dan Coats, R-Ind., said, said the panel needs to hear from people who had held key GM posts who may have knowledge of defects. GM chief executive Mary Barra endured a scolding at the Capitol Hill and vowed to return with answers once GM wraps up its own investigation. Panel members were frustrated over Barra’s inability to answer even questions pertinent to documents that GM itself submitted over to lawmakers.
At one point during the hearing, Sen. Barbara Boxer, D-Calif., told Barra: “You don't know anything about anything!” Sen. Claire McCaskill accused earlier in the hearing a GM engineer of not telling the truth on his role in the 2006 redesign of the faulty ignition switch, saying that GM “chose to conceal, rather than disclose” the defect for over seven years.
She cited an April 2006 document that shows GM engineer Ray DeGiorgio authorized the redesign of the faulty switch. The carmaker has told the NHTSA that the redesigned part was not assigned a new part number, which is a violation of its protocols.
The non-assignment also muddled engineers’ efforts to determine why switches in later-model cars were different. DeGiorgio said in an April 2013 deposition that he was not aware of changes to the ignition switch in 2006, adding that they did not approve a detent plunger design change.
