Jun 8, 2026Chest Clip, Buckle, Harness
I buckled my 2.5 year old daughter into her carseat and secured the magnetic chest clip. It very easily popped back open WITHOUT pressing the buttons. I attempted to get it to securely close several times and with light pressure it opens back up. This is extremely unsafe as it would likely not stay clipped in a crash or a child could very easily open the chest clip. After a quick online search, it appears that several others have had this issue. I just noticed it yesterday but I have no idea how long this has been occuring and, unless checked thoroughly every time, could happen to anyone.

pre-purchase inspection list. Back to the
