Evenflo is recalling over 56,000 child safety seats because of an issue with the internal harness that can increase the risk of injury in a crash.

The recall covers Transitions Three-in-One Combination Booster Seats made from Dec. 18, 2014 through Jan. 29, 2016. According to the recall notice, the central front adjuster button that loosens the harness may be within a child's reach and could potentially be loosened by the child. A loose harness increases the chance of injury.

Only seats used as forward-facing harnessed boosters can have this issue.

No injuries have been reported since the problem was discovered in late January.

Evenflo is notifying owners and will send a kit with a new seat pad and front adjuster assembly.
