I called Graco because the plastic on the buckles that go into the crotch buckle on our MyRide is cracking. I was told that they did not think it was a safety concern but couldnt say for sure and that I needed to use my best judgement on wether or not I used the seat. I asked about purchasing a new piece to replace them but was told that piece was not replaceable. Since my seat is out of its 1 year warrently they wont do anything about it. My seat is only 2 years old so it still has plenty of use left. Would you continue to use the seat?
