My brake fluid reservoir is also filled to correct amount, so hasn't leaked since I have never had to top it off.

Definitely not brake fluid. Color was lime green in the snow. My coolant tank was also down to about an inch left in it, all adds up to being coolant to me. Just dropped about an inch yesterday when I went out to check it before I started it. But no drops or sign of leakage underneath where I parked or in the engine bay at a quick glance before I left. But then held tight after a 3 hour drive to ski mountain and back. Checked this morning and held tight.

Thanks for the replies, but I don't think it is coming from the cap or reservoir. I checked all around the engine bay immediately after I saw the drips on the driveway and saw that everything was dry. Would have been fairly easy to see it coming from either of those, along with the snow that had been scraped up in the belly pan. The other thing that is boggling me is how it got all the way to the center-rear end of my car. If it were the cap or reservoir cap, it would have most likely dripped straight down under the engine. The drips I found on the driveway were located in the center, towards the rear seat of the car. Possibly dripping on belly pan plastic and pouring out when I move the car? But the times I found the drips on the driveway, I moved the car in reverse, so it could only fall closer to the front of the car.

I have a 2013 Subaru Legacy 2.5i Limited with 104k miles that I make sure to keep up with maintenance with due to it being my daily driver. The other day we had a huge 2 day snowstorm in NH, so like usual I warm up the car, dust it off, and move it into the street so I can snowplow the driveway. When I moved it back I noticed a large quantity of coolant in the snow. When I checked the reservoir it was down below the "low" line, about an inch left in the tank. Put it up on the lift later that day, couldn't find any drips, breaks, all visual hoses weren't dry rotted or cracked, all seals were dry and clean. Let it run in the driveway for 20 minutes. Nothing. So I topped off the coolant back to normal level. The next day, the same thing happens - start it up, drips all over the snow (less this time, the reservoir only went down about a half inch from "full" line). So I let it cool off thinking that cold start is causing it from quick pressure to cold cracked hose. Still couldn't recreate the leak. Today I dropped it off at my mechanic's. Comes back inconclusive. Told me they did a visual, didn't see anything, then pumped the coolant system up to 16lbs pressure and let it sit, held no problem. He told me to just keep an eye on it but the fact that I lost about 8oz of coolant scares me. Could have been over time, but I checked coolant level on the last oil change about 2 months ago and it was at the normal level. Anybody else have this problem or know what could have possibly happened? Any reason why the system would just decide to dump/overflow? Due to cold weather, snow, or any other known issues? Appreciate it.
