My ESP keeps kicking on when I'm driving on the highway going around very moderate curves between 65 and 80. It seems to be getting worse. It kicked on 5 times this morning. Not a good feeling -- am I truly slipping around a curve and in danger? These are not sharp curves at all -- in my Ford Explorer (not exactly a good handling vehicle) I dont' feel any lean at all. The car, and therefore the tires, only has 15K miles on it. I'm going to take it to the dealer, but any similar experiences from anyone? This can't be normal. My tires don't appear to be excessively worn in any way.
