I've done a search on the topic with no results but maybe I've been looking for the wrong thing. I have an '11 M3 with roughly 1k miles, I've hit 80-85 on the highway a few times and the steering wheel starts shaking a fair amount. I've gotten it up to 90 and the shake goes away. Tire pressures are fine, thinking its a wheel balance problem but am a little ticked it left the factory this way. I'll be in for my 1200 service in a few days so we'll see what happens. Just curious if anyone else has had this problem?
