Sweet smell in cabin after using "REX" engine

[i3eezy]

I make a 120 mile trip once a week and end up using the ICE.

When i get off the freeway a sweet (coolant?) smell fills the cabin.

Is this a known issue? Anyone else have this experience?

I don't really smell it while driving on the highway, only about 2 minutes after i get off.

What do you think it is?

Ethylene glycol (main component in antifreeze) smells sweet...you may have a coolant leak.
