I drive mine down a gravel road daily, one miles worth then I switch to 3 miles of dirt (sandy clay). On the gravel...when it is not maintained and gets the washboard effect the ESC warning light comes on for a brief moment. No worries - it is just telling you all the wheels aren't all getting the same amount of traction, at least that is what the owners manual states. The gravel also beats the living daylight out of me but my tire pressure is jacked up, the factory recommended pressure really does absorb quite a bit on the severely bumpy roads. Once again - the county doesn't take the best care of the road.
I also get the same results from the dirt road I travel on. They graded it all today and I can tell you everyone else was doing about 60-70mph down it - idiots
