“My air bag warning light/dashboard message has come on 7 times in the last 3 weeks, along with 4 other times in the 2 months prior, but the Gmc dealership will not investigate since it does not stay on. At the most recent event this weekend, I pressed onstar, and they ran diagnostics and emailed me the b0085 detected error code, but my dealership will still not investigate, since the light went out. The light has come on at startup and while driving. Warnings have come on 8/27/20, 10/5, 10/8, 10/12, 111/28, 12/2, 12/8(x2), 12/11, 12/14, and 12/19/20.”
