I discovered a leak pretty high on the right side behind the dog bowl. Probably the hose as it rubs against the engine as it's poorly positioned. I thought I heard a hissing sound one time going up a hill with a lot of throttle just after being on the highway for 2 hrs at 80 mph. The coolant level hasn't suffered much and I have an extended warrantee. Thinking about waiting till spring the have the dealership fix. Anyone else have this issue beforem, just a hose or something else?
