The fog problem is interesting, as the 2015 Outback had a problem with the windshield cracking. Maybe that is the reason. They installed a very cheap windshield in the Outback. Check the oil every 2,000 miles or less because Subarus are known for consuming a lot of oil. If it is low, buy some oil at the autoparts store and fill it up with the correct type. Do you have the 2.5 or 3.6 engine?
