About a month ago, I was in a parking lot when a Jeep backed up into the FEH. Did some damage to the bumper and put a leak in a coolant line. That's when I first learned about the electronics coolant tank. I would drive for awhile and then the dashboard would light up with the triangle and exclamation mark. I would pull over adn pour more coolant in. First I thought it was the engine coolant but checking the manual showed that it was the electronics coolant. The other guy's insurance took care of the bill.
