Judging from previous responses, I'd think there is either something wrong with my car, or with me. Or, maybe a second impression would change my opinion ...
On my trip home after taking delivery, I bordered a large thunderstorm complex for 30 or 40 miles and experienced some blustery side winds. It was a white knuckle experience for me at Interstate Hwy speeds.
It is a fairly light, high profile vehicle. So, it is not surprising it is not a champ with regard to strong cross winds. IMO, it would be an improvement for the ESP to address cross winds. But I see no indication that it does. 2¢
