Driving straight on the highway ~50mph the car seemed to be drifting to the right as though being blown by heavy winds, although there was little/no wind that day. I applied a typical, slight adjustment to the left but the steering wheel resisted my input, as though somebody was holding onto the steering wheel and applying pressure to the right, after a split second, the opposing pressure released and the wheel overcorrected to the left followed by the identical response when I attempted to correct back to the right. It continued to do this every mile or so, for approximately 9 miles, until I turned off the highway. At lower speeds (city driving) the steering is completely normal. The same thing has happened on three different stretches of highway in the jacksonville area. I have tried different lanes, checking the tire pressure, and I had the dealership check it but they could not duplicate the problem. Applying light/steady/even pressure in the direction of the desired correction, without applying pressure beyond the point where you feel the resistance seems to help prevent the overcorrection problem. On 9 Jan, when crossing uneven lanes on the highway due to construction, the wheel pulled to the right more than you'd ever expect under these conditions and I ended up half way into the next lane. Luckily there were no cars in that lane otherwise it would have resulted in a collision without a doubt. That was followed by an overcorrection to the left, and again back to the right. I had to slow down below 40mph before the resistance in the steering eased up. This incident happened on a highway that I am very familiar with; I have traveled it without incident on my way home from work for the past 6 years, and I was prepared for the transition between the two uneven lanes. I have driven other vehicles with epas. This is not normal!!
