On my 05 MDX I am getting a faint smell of antifreeze. The vehicle isn’t leaking or using any at all. Any suggestions on what it could be? Also it’s not overheating either. Thanks for any input!

Could just be a small leak thats not visible from the top of the engine. Have you checked under and in back of the engine?

Where are you when you're smelling it? If its inside, it could be a leak in the heater core or associated hoses. Under the hood, look at the heater valve (passenger side firewall, with a cable going it). They're known to drip some coolant, and it'll fall on or near the exhaust, making the smell more obvious.

I have noticed a similar smell. For me the smell is strongest at the front grill. I'm going to follow this thread.

The coolant color in the reservoir is still blue, the smell is predominately from the front. I believe it’s the original radiator.
