Combi USA recalls more than 33,000 child seats

DETROIT - Combi USA is recalling more than 33,000 child car seats made before January 2013 because the harnesses aren't strong enough to meet federal safety standards.

The Charlotte, N.C., company is recalling the Coccoro, Zeus Turn and Zeus 360.

The National Highway Traffic Safety Administration says the seat straps don't meet minimum strength requirements. If there's a crash, children may not be properly secured.

A company spokeswoman says the seats are still safe to use because the harness as a whole meets safety standards. She says one part of the harness that includes a plastic button failed strength tests. Seats made after January 2013 don't have the same problem.

Combi will notify registered owners and send out free harness replacement kits starting in February. Owners can contact Combi at (800) 543-7734.
