Greetings from Wisconsin. I hate that my first post here is about an issue with my new to me truck. So have had my 2015 PRO4X for just over two weeks now. Love the truck, but have had a few issues with it already (leaking rear diff and sonar sensor beep after getting wet). Current issue is on the way to work this morning the truck stopped blowing warm air from the vents. I turned the heat off and drove a few miles. Turned the heat back on and it was warm again. Is this the air in the system issue that is fixed by slightly filling the coolant reservoir a bit past the max level?
