So about a week after the warranty ends I get this message in the DIC. 2017 Grand Sport 7 speed. Didn't seem to affect anything until I went on my favorite exit with the off camber dog leg. I usually hit this one at around 95 or better. Now I can feel the rear end fighting itself. Anyone have any idea what sensor is failing/failed? It was an intermittent warning on the DIC until this week. Now it shows up on every start. Any help is always appreciated. PS, all fluids have been changed in the transmission and the axle. And yes I used the GM gear lube with the limited slip additive in it.
