I just bought a new Metalic/leather titanium interior Acadia SLT and I'm very happy with the style and driving comfort. But this week I noticed my drivers side lombar back support lever was not doing anything. I kept playing with it for a bit and the whole handle came loose, also the passenger side did the same. Has anyone else tested this yet? They were not working at all.Well you guys should check yours, the dealer is replacing them this week.
