My steering wheel gets really stiff at about 100km (60mph) and above. It makes fine tuning really difficult and I kinda zig zag from line to line. Adjusting the steering sensitivity has no effect (comfort/standard/sport). I did discover that wiggling the wheel (a few degrees back and forth rapidly but not enough to change direction) loosens it up for about a minute before is gets stiff again. EDIT: It has been like this since I bought the car in November 2014. (some have suggested a recent update is responsible) Is this normal? A common issue? Or, should I take it in for service?
