2023 GMC Sierra check engine

HammyD · May 11

So I have a 2023 Sierra less than 6000kms I got a Check engine air filter system message about two weeks ago took it to the dealership and they said it was a glitch and nothing was wrong. Today it comes back mind you I think I lifted the hood once to put windshield washer in so no mods whatsoever and obviously something is wrong I took it a friend’s shop and he put his scan tool on it and said no codes. Any suggestions or thoughts would be appreciated

Thanks in advance

I always press the OnStar button whenever an indication light comes on and ask the rep to run a diagnostic. If they find anything I have then send the info to my email.

Never thought of that. GM forced me into 3 yrs so thanks for the tip!

I guess maybe I should have subscribed I think I got 3 months free but pretty sure it has expired now. I guess it’s back to the dealership for me hopefully they find something this time and don’t try and tell me it was a computer glitch again
