It is plausible if you live in the midwest or northeast and you dont maintain lubrication on the pivot of the hinge... its possible.Sorry; I've only had mine on for 1 month. I did a lot of research on the different ones out there, and have not heard reports of the hinges seizing.
Just to share a story I read recently. Not sure if it is true or not...
Woman driving on the freeway and had oversized tires and an oversized spare on the factory carrier. The carrier cracked, broke off while she was on the freeway. Tire hit two other cars but no one was injured. Her insurance denied her claim since it states in the owners manual states X weight but she exceeded that by quite a bit. We seem to forget that safety should come first and to do the right thing. IMO, lift, bigger wheels and tires, speedo calibration and tire carrier/hinge should all be installed together for safety sake.
