This has been gradually happening so I brought it to the dealership and they confirmed that they dont see any leak. So my question is where is the antifreeze going?

I just filled it and travelled 6 miles and came back home and the antifreeze tank was half empty. Where is it going? I took the flashlight and looked everywhere no luck. But in the car when I drive, I was smelling antifreeze.

What gives?

 

Sounds like a pinhole leak somewhere. Something like the turbo cooling line leaking onto the hot exhaust or similar. Maybe leave the engine running and search around til you find it. A more expensive method is using a dye that shows up under a black light.

 

If you're smelling coolant while you're in the car, you should be suspecting the heater core.
Check for wetness on the floor of the right side and also the driver's side.
