Britax Child Safety is recalling 60,000 car seats.  It has been reported that children can bite off a piece of the harness pad and choke on it.  The recall is for the Boulevard 70-G3, Advocate 70-G3 and Pavilion 70-G3 models.
U.S. regulators say the seats were made with softer chest pad material that can be bitten off and chewed by children.
There have been three reports of children biting off pieces and gagging on them.  The company plans to send new new pads for free to people who registered the seats. However, other owners can call (888) 427-4829 to receive new pads.  The seats can be used without pads until new ones arrive.
