Barra Confidante Still at GM Was in Ignition-Flaw Debate

A top product-development executive still working at General Motors Co. was, as an engineer, involved in deliberations about a deadly ignition flaw kept from the public, newly released documents indicate.

Doug Parks, a vehicle chief engineer for the Chevrolet Cobalt in 2005, was involved in the debate over whether it was worth the cost to redesign a faulty ignition switch that had been installed on millions of cars, according to company e-mails and documents released yesterday by congressional investigators. He would later become vice president of global product programs under Mary Barra, now GM’s chief executive officer.
