General Motors CEO Mary Barra stepped in front of a House congressional committee Wednesday to offer a status report on the company's handling of a recall that is responsible for at least 13 deaths. GM's Chevy Cobalt had a faulty ignition switch that, while driving, could switch into the accessory position, making the airbags unable to deploy in the event of a wreck. It came to light earlier this year that General Motors knew of this issue for years before issuing a massive recall.

Barra appeared before a House committee earlier this spring to answer questions, and recently, the company released an internal report that shows a widespread cultural problem with fear of delivering bad news.

Lawmakers said Wednesday they remain unhappy with the auto giant and hope to continue investigating the company as it works to sort out its issues. Some Republican lawmakers wondered aloud whether GM has committed a widespread cover-up.
