This just started happening in my 2008 Tahoe LTZ and needless to say it’s pissing me off!! I only have 74k miles (I don’t drive a lot) and I recently picked it up from a maintenance visit at the dealer. I notice it only happens when I’m stopped; I hear ding, ding, ding, ding, then Stabilitrak Off, red brake symbol, Traction Control Off, and Service Brake System pop up on the dash. Eventually all disappear except for the little yellow road sign with the squiggly lines. No shutting off, no hard shifting, no losing power.

I can still drive fast and brake when I need to. So far, it’s more annoying than anything else because it shouldn’t be happening. But the craziest thing is, I called to ask my dad about it, he had no idea; and about two days later he called me furious saying the same exact thing starting happening to him 600 miles away in his 2015 Buick LaCrosse. WTH!!!!
