Model 3 Weird Smell

Maybe a collant leak?

From the web: "If the cooling system in your car smells sweet, then you should have your unit checked immediately. The sweet smell is often the cause of toxic liquid ethylene glycol or antifreeze. This smell is the result of a leak in the cooling system."

From other posts...the Model 3 only has one coolant circuit for all its system...so HVAC uses the same coolant as the battery. So if you have a coolant leak...you could also be affecting your battery.

I don't believe the coolant loop goes into the passenger compartment. Many ICE cars have the coolant loop going through a heat exchanger to provide heat. Thus a coolant leak ends up in the cabin.
 
Has anyone been experiencing a weird smell in their model 3 when the HVAC is turned on?
Yes, there is an odd, new car/something burning smell. I'm hoping/expecting it will go away after some usage.
Also, I've noticed that smells from items in the frunk seem to leak into the HVAC (spicy takeout food in the frunk)...I suspect the rubber seal on the frunk to the hood isn't perfect.
 
A damp musty smell is not good so early. I would take that to the SC.

Mine smells weird when it has been sitting in the sun, but it started after I got my tint installed. So I think it is the adhesives from that. It is a chemical smell vs musty tho.

I thinking you may be right because I just got my windows tinted as well and that's when I noticed that smell. Do you have any ideas on fixing it or is it stuck in there for good?
