Graco is recalling nearly 3.8 million car safety seats because children can get trapped by buckles that may not unlatch.
The recall covers 11 models sold from 2009 through 2013.
They include: Cozy Cline, Comfort Sport, Classic Ride 50, My Rid 65, My Ride with Safety Surround, My Ride 70, Size 4 Me 70, Smartseat, Nautilus, Nautilus Elite and Argos 70.
Graco says there have been no reports of injuries due to the defect.
The company will send replacement buckles for free to owners who registered their seats.
Owners who did not register their seats but want free replacement buckles can call Graco's consumer hotline at 800-345-4109 or visit the company's web site.
