More than 500,000 child car seats recalled

More than 500,000 car seats manufactured by Diono are being recalled because they may not adequately protect children in a crash.

The recall covers the Radian R100, Radian R120, Radian RXT, Olympia, Pacifica and Rainier convertible and booster seats. They were made from January 2014 to September of this year by Diono, once known as Sunshine Kids Juvenile.

Diono, based in Sumner, Wash., says it has no reports of injuries. The problem was discovered in testing.
