3.7 million Graco car seats recalled due to buckle issue

In one of the biggest such recalls ever, Graco has agreed to recall 3.7 million child car seats manufactured in recent years -- even as it officially contests a government request to recall nearly 1.8 million more -- over a buckling issue. The National Highway Traffic Safety Administration (NHTSA) announced Tuesday that Graco is voluntarily recalling 11 of 18 model seats that the government agency had asked it to recall.
