She was concerned it was on the recall list.It turns out - that specific child car seat - is not.0154 Relieved knowing that mine was not affected. However, being a mother, I could even imagine how I would feel if one of mine was the one affected. Currently, infant seats are not on the recall list - only the child seats.But the government's road safety watchdog still wants Graco to recall 1.8 million infant seats - because they have the same buckles.But Graco says the infant seats are used differently - and the entire seat can still be removed even if the buckle is faulty. Danielle Kessenger a Child Passenger Safety Tech for Safe Kids says the buckle doesn't affect the crash worthiness of this seat, but it's more of a concern of getting the child out in a medical emergency. Danielle Kessenger/Child Passenger Safety Tech 51004051221 If it were a medical emergency and you need to get the child out because of choking or a seizure, that would be a danger.
