The affected child seats have a red harness adjuster button that may stick in the down (harness release) position allowing the shoulder harness to loosen. If the harness loosens, the child may not be properly restrained, increasing their risk of injury in the event of a crash. Britax will notify registered owners and send them a remedy kit that includes a lubricant to apply to the harness adjuster button, free of charge. The recall is expected to begin on August 17, 2015.
