Families demand GM accountability

General Motors boss Mary Barra faced harsh questioning by US lawmakers and victims' families over an ignition switch fault in some cars linked to at least a dozen deaths.

The chief executive of General Motors Mary Barra faced harsh questioning from US lawmakers, who demanded to know why GM had waited nearly ten years to issue a recall on cars with faulty ignition switches.

Lawmakers said it would have cost GM just $2 to replace the switch.

Ms Barra has apologised for the switch fault, which has been linked to at least a dozen deaths in road crashes.

But family members protesting outside the hearing demanded more than an apology: they said they wanted accountability, and GM to pay.
