WASHINGTON — After a series of blistering statements from lawmakers Tuesday, General Motors’ chief executive, Mary T. Barra, expressed deep remorse at a House hearing for the automaker’s decade-long failure to recall defective vehicles linked to 13 deaths.
But Barra offered scant new information in her opening remarks about how and why GM repeatedly failed to fix faulty ignition switches on Chevrolet Cobalts and other compact cars, despite conducting multiple internal studies of the problem since 2001.
“I cannot tell you why it took years for a safety defect to be announced in that program, but I can tell you that we will find out,” she said, adding, “I am deeply sorry.”
