Thanks for the advice. I will try it out

We’ll this is a real kick in the nuts. I’m in the middle of a night shift trying to figure out what’s wrong with my brand new truck. It sounds a lot like what you started off with... 2020 GMC 1500 Denali with 263 miles on it. I’ve had it for 3 weeks and the check engine light has came in twice now. First time I thought it was a fluke, because it cleared quickly, but now it’s in again. I can’t feel anything wrong with the truck. There is a weird clicking noise on start up idle that I don’t remember earlier, almost like the belts are wet or something. The other thing is radio glitches. Sometimes when I remote start it and get in quickly, or I get in and start it up with the button inside the screen glitches on and off and the radio cuts in and out for about 20 seconds. Really irritating. I’m going to try and get some codes read in the morning and maybe stop by the dealer between shifts. Will keep you updated.. Any one else have the same issues? I looked up my VIN and there are no recalls or updates apparently. It was manufactured 03/20 in Mexico.
