That notice has been happening to my Trailblazer since I bought it in June 2020. My
service department can’t figure out why it does that or what’s wrong with it. When that Power Steering notice comes on, all of my features turn off and I can’t turn them back on. Collision alert, hill assist, auto stop/start, traction control, lane assist, parking alert... etc. All turn off and I can’t turn them back on until the notice goes away. Mine also starts driving funny when that turns on. Only word to describe it is wobbly. The wheel starts to get wobbly then gets stiff.
