That really sucks man. I had a check engine light on my 2020 AT4 485 miles!! this morning when I went to work, but it was gone after work? I hope it was nothing, but makes me mad when you know they are new.

you light still one? let me know what you hear from dealer. Ty

same thing happen to me, I remote started my 2020 sierra at4 with 486 miles and when i got on the check engine light was on. after work I didn't use remote start and light was gone?? it makes me mad! brand new truck and a engine light on?? wtf.
