Nearly 150,000 of the cribs on recall carry the Fisher-Price logo.
The agency is aware of four deaths of young children who suffocated in the cribs, which have a side that moves up and down to allow parents to lift children from the cribs more easily.
The Stork Craft cribs have had problems with their hardware, which can break, or with assembly mistakes by the crib owner.

This would not be the first time cribs have been taken off the market because of this danger.
Nearly five million cribs have been recalled over the past two years, and the CPSC has talked about banning drop down sides altogether.
In July, Simplicity recalled 400,000 drop side cribs after one baby, maybe more, died.
The danger is the crib's plastic hardware can break or deform, causing the drop side to detach, creating a space between the drop side and the crib mattress.
Infants and toddlers can roll into this space and become entrapped which can lead to suffocation.
At the time of Simplicity's July recall, the CPSC said it was aware of 26 incidents where the drop sides had detached.
The government agency says Tuesday's massive recall will be part of a larger effort to put in mandatory rules to make all cribs safer.
