Has anyone experienced a buzz in the steering column? Its very annoying on certain road surfaces, and not nice for a brand new $100K car.
It only happened once on a poorly surfaced back road weeks ago (so I didn't mention it during the 1200 mile service), but it then happened ONE day after that, on interstate! I now have a 1000 mile round trip this week, and am hoping I don't hear it again.
Two, is it normal to hear the rear suspension working on a bumpy street? I wouldn't call it rattles, but just more noisy than any recent BMW, including a 335is and Z4 on runflats. I assume its the directly connected subframe.
Now the good news, I have thoroughly enjoyed the luxury and performance of the car, whether commuting or interstate trips, or blasting through back roads with friends. I've not had a chance to really get into it since the break in service except brief runs on on-ramps, so I can't comment whether I feel more power now or not. Its either too cold, too wet, or too much SLOOW traffic. I don't understand why people take 2 city blocks to go 0-35, and then zoom up to 50 on the next down hill.
Twice I have done a 1-2 shift on throttle, and had traction control really KILL the power. There is definitely an art to giving it just enough but not too much throttle for max acceleration in first or second.

Both the steering vibration and the rear suspension are well talked about issues with the F10 M5. I'm not going to call them problems, since it seems to be hit or miss. I've never experienced either before and I'm at nearly 50,000 miles.
Also, you have nailed it my friend. It IS an art. My best advice is that if you really want to fight traction issues is to try to install 305mm tires or install the Michelin Pilot Sport Cup 2 tires, but then can't drive in the rain with the Cup 2's. Traction is vastly increased with the Cup 2's, and slightly increased with 305mm tires. There is a reason why the new head of BMW M has stated that AWD is in the plans for the next generation M5.
