About half of the millions of General Motors vehicles recalled over a faulty and sometimes deadly ignition switch have been fixed, nine months after the first recall, according to a new report.
GM (GM) estimates that more than a million unfixed vehicles, of the more than 2.3 million needing a fix, remain on the roads, a spokesman told the New York Times. The automaker has promised a large campaign — amidst continued criticism for not recalling affected vehicles when evidence of an issue first emerged — to reach owners whose vehicles maybe have the defect, launched a social media campaign and staffed a recall call center with 72 employees.
The ignition switch problem, which has been linked to the deaths of at least 30 people and dozens more injuries, stops airbags from inflating and affects both steering and brakes.
