Just getting back to this... So I never ended up taking my truck to the dealer. Before my appointment, I started noticing this smell in other places outside of my truck, particularly when there was a breeze on my face, much like vents pointing at you in a vehicle. I google why do I smell something no one else smells and it returned pantom smells. This can be caused by a whole host of things. For me it was just sinus pressure due to allergies, according to my ENT. After a course of steroids, no more smell. Crazy!

Good additional details to note! Thanks

I recently started to notice an exhaust or gas smell coming through the vents in my 2024 Sierra. I mostly have the climate set to Auto so I have to play around with, "does it happen with heat on/Off", "AC on/off" etc. I have an apt with the dealership but I would like to see if anyone has come across this? If so, what did you or the dealer find? If not, what are some additional troubleshooting tips you would recommend? Thank you in advance!
