So I was going through some curves on the road today, and when turning in on one, the steering got VERY heavy, as if it was non assisted manual steering, with a grinding noise. It only lasted for half a second, but if someone had lesser arm strength they would have ended down in a river. This hasn't happened for several hours of driving home after the event. I did check the steering arms and everything associated with the wheels, nothing obvious. No error messages on the dash occurred, will check with a scanner for pending codes. Has anyone heard of this happening with these cars? Because that is a serious safety concern. (I am contacting the dealer Monday)
