Federal safety officials on Thursday ordered child seat maker Graco to explain why it decided to exclude seven infant seat models from its recall of 3.8 million child seats last month and to hand over a trove of other related information.
In the child seats recalled, the buckles may not unlatch, making it difficult to remove the child from the seat. That could increase the risk of injury in a crash, fire or other emergency when a speedy exit from the vehicle is required.
