Certain Evenflo Big Kid Factory Select booster seats, Model Nos. 30911173AD, 3091967AD, 30911118AD, and 30911120D, shipped between August 6, 2012, and September 18, 2012, fail to conform to the requirements of Federal Motor Vehicle Safety Standard No. 213, “Child Restraint Systems.” The subject seats were originally manufactured solely for purposes of retail display and not to be sold at retail. Therefore, the seats were packaged without the instruction manual or the required registration card. However, the seats were inadvertently shipped to Evenflo’s institutional customers (i.e. hospitals, government agencies) to be given to families. None of the affected units were sold at retail stores.
