All Accents seem to do this so whatever it is, it's a design flaw. Thankfully, it seems to perpetually sit at the level it's at right now in my car and goes no further. The last time I topped it up, even to the 'low' point on the overflow, it lowered itself right back down to where it was before within a week.
Granted, I do 130-140* on the highway every day for a constant 15km stretch, then 70-100 the rest of the way. That little engine's gotta get hot.
* following the speed of the rest of the traffic in the fast lane during rush hour - remember folks, if you're the only one doing well below what the rest of the traffic around you is doing, YOU'RE the potential problem
