NHTSA Complaint #11640766 — 2019 GMC TERRAIN

Headlights flicker when auto stop releases and clicks back on to move the vehicle. This happens when it wants too but usually at the same time service parking brake will pop up, followed by steering is reduced, drive with care.. Lets see what else. Carplay no longer works. No sound. sd card error pops up. Car will not play music through a cord but will via bluetooth, but charges a phone. OnStar light flickering between green and red until I turned off power to the liftgate. (manually clicking over knob to disable) Headlights flickering can cause accidents. Sure hope there's no epileptics out. Yes, orielly. I have documentation, photos, videos, take your pick I'm here to help. Not evaluated at dealer or mechanic, who can afford labor rates? This has been happening for months and I will continue to report till something is done or lives are cared about.
