The new executive in charge of safety at General Motors says parts will start arriving in a little more than a month - but it'll take all summer to fix the 1.6 million vehicles recalled because of faulty ignition switches. ABC News reports the newly appointed vice president of global safety at GM says it'll take at least all summer to fix the 1.6 million vehicles recalled because of faulty ignition switches, with the first shipments of parts scheduled to arrive at the dealer the week of April 7. GM expects to have one million replacement parts in the field by the end of August. Jeff Boyer says part of his job is to find out why the recall came 10 years after GM was aware of the problem that's been blamed for a dozen deaths. GM is launching a web site, 800 number and twitter account for owners with questions.
