I was on the highway & had just passed a 18-wheeler & I saw some mist in his headlights. I had just driven through rain, & thought I was kicking up road mist, but I got that uneasy feeling In the pit of my stomach. I don’t recall seeing any idiot lights illuminated at the time. I got to my destination a few miles later & when parked, got a whiff of antifreeze when I was retrieving luggage from the trunk. Next day, I popped the hood & saw coolant level low in bottle & added a gallon, but eventually saw a stream emanating from behind the passenger wheel. Got down & saw a waterfall just behind the splash shield. I had emptied about a gallon into the bottle by then. I’m putting it on a dolly & towing it an hour back home to troubleshoot on a neighbor’s lift. Any ideas what this might be? I’m not sure what would dump coolant back that far? Think the 2015 extended warranty might cover this? Here’s a pic of where the coolant was leaking from: cold engine atmospheric pressure. The view is from behind the driver front wheel….passenger front wheel in view behind the leak.
