report from the NHTSA claims that harness buckles stuck in the latched position can increase a child’s risk of injury in the event of an accident, fire, or other emergency. In some cases consumers have even been forced to cut harness straps in order to free their child from the restraints. Graco estimated that less than one percent of car seat models named in the recall was affected by a malfunctioning harness buckle, The Associated Press reported.

In a letter to Graco, the NHTSA also criticized the company for not including the seven models left out of the recall. The U.S. government’s highway safety regulator said the recall should include an additional 1.8 million car seats, making it the largest car seat recall in U.S. history. The NHTSA also "encourages parents and caregivers to consider acquiring an alternative car seat for transporting children until their Graco seat is fixed."
