The safety harness in a child’s carseat is meant to prevent injury in the event of a crash. Those safety devices don’t do much good if the tiny occupant has already undone the restraints. Which is why Evenflo has recalled more than 56,000 carseats.

Evenflo announced this week that it would recall certain Transition 3-in-1 Combination Booster Seat models after determining that the central front adjuster button may be within a child’s reach.

The button is used to loosen the seat’s internal harness. If a child were able to reach the button they could loosen the internal harness, increasing the risk of injury to the child in the event of a crash.

In a notice [PDF] posted with the National Highway Traffic Safety Administration, Evenflo says model numbers 34411686, 34411695, and 34411029 are affected by the issue. The carseats were produced between Dec 18, 2014 through Jan. 29, 2016.

Evenflo will notify owners and provide a remedy kit that includes a newly designed seat pad and central front adjuster button.
