Government was aware of GM problem in 2005, documents show
Laura Christian's 16-year-old daughter Amber died inside a Chevy Cobalt when the airbag failed to go off in a 2005 crash -- the first death to be linked to GM's faulty ignition problem. No recall was issued at the time, and the news never reached the public because Amber's adoptive parents reached a settlement and signed a confidentiality agreement with GM. Jeff Glor reports.
