“My 2021 Acadia just stooped working as COMPLETLY SHUT OFF. I had no power to contact OnStar or more importantly to put my 4 ways(Hazard lights) on to signal or warn other motorists that there is a problem ahead. I could not push the vehicle as it is locked in gear because of the termination of power. I have had this exact problem happen 3 times leaving me and my family stranded on a busy road with nothing working. On each occasion I have removed my family from the vehicle in fear of being rear-ended! …”
