SAN FRANCISCO (KGO) -- Harmony Juvenile Products is recalling nearly 150,000 Big Boost Deluxe seats.
The National Highway Traffic Safety Administration says a crash could cause the seat belt to put excessive force on a child's chest, which could increase chances of injury.
The company is still working on a fix for the problem.
