My aunt drives an 08 Equinox that is nearly out of warranty. The mechanism that holds the fabric of the seat to the frame keeps coming off. This has been a recurring problem that the dealer has fixed several times, and is finally going to replace (on one seat). Is this a typical problem on the first generation Equinox/Torrents? I'm new to these type of things, so if I'm not be specific enough, or it is confusing, let me know and I"ll try to explain better.
