I wouldn't have raised this as an issue if it was only snatch of the wheel on the sort of surface you describe, but this is not the case, it is bad enough to shake the wheel violently on ordinary give and take A and B road surfaces where I am traveling at between 20 - 70 mph and will shake the wheel out of my hands if not held really tightly. This is particularly dangerous on corners and makes it very difficult to place the car.
I know it is all relative and one mans wheel shake is another mans 'feel', but believe me, I am not being oversensitive about it, this is a real problem. Having said that, it is not fair to make a big fuss at this stage as my car hasn't yet had its' PDI, as I collected it directly from the factory, and it didn't get to the dealer first, it is booked into him in a few weeks time [he is 135 miles away, so not that convenient to drop by] and we will see what happens after that. It could come back as smooth as a baby's bottom. I'm only wondering if other cars have this problem, which they have, what may cause it and what has been done about it, maybe a faulty batch of dampers for example.
It is detracting from the driving experience, and if there are other cars with the same problem, then we can help each other.
