WASHINGTON (AP) -- House members say they still have many questions about General Motors' delayed recall of small cars, including whether the company's culture has truly changed.
A House subcommittee is hearing testimony Wednesday from GM CEO Mary Barra and attorney Anton Valukas, who recently completed an internal investigation on the recall of 2.6 million Chevrolet Cobalts and other cars.
Congress wants to know why it took GM more than a decade to recall the cars, which have defective ignition switches. GM blames the switches for 13 deaths.
Republican Rep. Fred Upton says this week's recall of another 3.4 million cars with faulty ignitions shows the problem didn't end with the first recall.
Rep. Diana DeGette, D-Colo., says senior executives at GM, including Barra, should have acted sooner to change the company's culture.
