I got my child out of her Chicco fit360 at a store, when I came out to put her back in, the chest clip release buttons were stuck. The chest clip would not close together because the open buttons were stuck. I kept pushing them trying to get them to release, I tried pushing them out from the inside & finally got them to release. After the hour drive home, when I went to open the chest clip, the side that had the buttons stuck completely fell apart in my hand when I pushed the release buttons. Every single button, piece, spring, etc fell apart into my hand. I chatted with Chicco & they are sending me a new chest clip.
