I just concluded getting an ID on my.GMC.com based on recommendations that it might help me get service history on our 2012 Acadia SLT more easily. Well, once I got on the site and followed a link for Warranty Tracker I found that our Acadia appears to be eligible for this Special Coverage Adjustment. It may have nothing to do with the "service air bag" warning light we are getting repeatedly, but then again it may. Does anyone know anything about the referenced adjustment? The date of the adjustment is June 13, 2019.
