The questioning became contentious at times but it did not appear to rattle the GM chief executive, who rose to her current job in January. However, she repeatedly did not provide the answers House Energy and Commerce panel lawmakers were seeking, citing the company's ongoing internal investigation.

Barra was called to testify as part of congressional probes into GM's delayed recall of 2.6 million vehicles that could have faulty ignition switches that unexpectedly cause engines to stall and prevent air bags from deploying and power brakes and power steering systems to operate normally.
