DETROIT (AP)-- Nearly 40,000 child car seats are being recalled over safety concerns.
Combi USA is recalling more the car seats because they can transmit too much force to a child's chest in a crash.
The recall covers certain Coc-Coro Convertible Child Restraints with a model number of 8220.
Government documents show the problem happens when the seats are installed in a forward-facing position and secured only with a vehicle lap belt.
Combi said there is little to no risk in real-world crashes and has seen no reports of injuries however the company said they will notify owners and send them a cover that will reduce the force on children's chests.
