  1. How did you fix it? I’m having similar issues thanks
  2. Iv noticed over the past week or so that every time I cold start my 2021 gmc sierra 5.3 it makes this weird sketch / whining sound for about 2 seconds when cranking then goes away. Only on cold starts it makes this sound. If I go out and start the truck after driving it does not make this sound. Anyone else experience this problem or knows what it could be. It’s driving me nuts my truck only has 40000km. IMG_5997.mov
