Nearly 800,000 
child safety  seats produced by Dorel Juvenile Group are being recalled due to 
safety  harness problems, the National Highway Traffic Safety 
Administration  announced Monday. The recall covers 
booster,   convertible and infant seats made by DJG of Columbus, Ind. At issue is   the harness locking and release button, which does not always return  to  its locked position. This can allow the harness adjustment strap to  slip  back through the 
adjuster as a child moves around in the seat and results in a loose harness, increasing the risk of being injured in a crash.
