Vehicle went to GM for recall repairs on 02/24/25 the morning after when I cranked my car it was dead. Jumped the car off then began hearing a ‘clicking noise’ GM advised I replace my serpentine belt as they noticed it needed replacement when doing the recall repairs. 02/26/25 serpentine belt was replaced but car still seemed to have power issues when cranking. 02/27/25 car barely cranked then while driving down the highway I lost all power and power steering to the vehicle. There was no warning, no check engine lights etc. The screen went black then car shut off then the screen said ‘press start to restart.’ I was BARELY able to get the vehicle safely off the road with vehicles in front, behind, and in the other lanes. It could have caused a fatal accident. GMC still has my vehicle with NO UPDATE on replacement engine timeline.
