GM Recall : How the ignition switches fail

It was a deadly defect in an ignition switch that led to the recall of millions of GM cars like the Cobalt and the Ion and the confirmed deaths of almost 30 drivers, with close to 200 more being investigated.

In "The Switch From Hell" -- the premiere episode of the fifth estate’s 40th season -- Bob McKeown investigates what and when did GM and Transport Canada knew about the problem -- and reveals startlingly new information about fatal crashes in Canada.

For GM it all began to go wrong along a stretch of highway in Georgia on March 10, 2010 when Brooke Melton, a nurse outside Atlanta, died in a crash. In this excerpt from "The Switch from Hell" we look at how the search for the truth of what happened in that crash led to the discovery of a deadly defect and a corporate coverup.
