Select models use a harness crotch buckle which may become resistant to unlatching over time, due to exposure to various contaminants (like food and drinks) that are present in everyday use of the convertible car seat or harnessed booster by toddlers. This may make it difficult to remove a child from the vehicle. There is no such risk if the buckle is functioning normally. These convertible car seats and harnessed boosters meet all requirements for crashworthiness under the federal FMVSS 213 safety standard and can continue to be used to transport your child safely, if you are not experiencing difficulty unlatching the buckle. Importantly, Evenflo has received no reports of injuries to children in connection with the use of this buckle on the seats that are subject to this recall.
