2018 HVAC Smell

Hey guys. So for those of you with a 2018, have you guys noticed any faint and sporadic weird smells when you're running the heat? I commute a lot of miles, so I've already racked up 17k miles, all the new car engine smells and stuff they lather it with for transport at sea has already burned off long ago. So that's not the problem here.

This is more recent development within the last two days. Dare I say it smells like the faint smell of coolant, but I really only catch wafts of it sporadically. It's not a consistent smell; but it's definitely there. I don't smell any coolant in the engine bay, nor do I smell coolant when entering the car. It's only sporadically when the heat is running and the car is warmed up

Anyone else got anything funky like that? Insight? Thanks.

Just over 5K miles on my 2018 Signature and I haven't experienced any such problem.

None here.

Have you checked the coolant level to see if it has dropped at all?

Hey guys, thanks for the reply.
@idrive Coolant levels is just below the F marker (normal).
@Tosko Also the A/C is not on when the heat is running

Knocking on 10K miles, and I haven't had that type of smell. I've had a few other odd odors, but I don't think I can legally expand on that... lol

I am about to hit 50,000kms (31,000 miles) in my '18 Signature and I have never had any smells come from the HVAC like you're describing. Heat is being used lots, too, we have had a very very cold winter thus far so the heat is always blasting in the car.
