To those that say it's not a design issue, I disagree.
I, myself as an engineer, when I design a product, I design it for 100% of my customers. I don't design a product and say for this percentage of my customers it will perform this way, and for that percentage of customers it will perform that way. My products aren't a crap shoot. Anything that adversely affects peformance in any way that was not planned is a design flaw, even it happens to a certain percentage of products. Tolerance stack ups, incompatablity analysis, failure mode analysis, and testing regimen should have brought this problem to light before production. That's why engineers do those things in the first place. If their R & D process didn't detect this problem, then perhaps they need to take a long hard look at their R & D process. |

Update:
Took my car in this morning to have them look hub/wheel interface based on the latest bulletin noted earlier in this thread. I know this is most likely not the issue and if it's not fixed, I will be calling BMWNA to start the whole "fix it or give me a new car" process. I had my Dad drive my car this weekend and asked him (without telling him specifically) if he noticed anything strange in the way it drove. He said "it drives great, with the exception of this steering wheel shimmy." That just further solidified the fact that I'm not imagining the issue. Also, my loaner this morning was a brand new '13 F30 Sport with 325mi on the odometer. Between the drive from the dealership to my office, there was ZERO vibration.

Hi everyone,
I started a survey to try to substantiate the link between the steering wheel vibration and the Dynamic Handling Package. Please take a minute and answer the survey at http://www.f30post.com/forums/showthread.php?p=12875547 Thank you! |

Definitely there is some issue in TQM, but what it is at this stage, even BMW may not have fully identified or appraised. Sure we don't expect something like this from BMW, what I ask, are we sure how big an issue this steering vibration really is? Also is every claim to steering vibration, the same issue? Forums are known to skew statistics. We have the issue here in the UK where the BMW diesel engines, (M47 in particular) are putting failing swirl flaps through the engines with total write-off. No one can establish the percentage of engines that are failing. BMW say it is small, but forums make it appear as a massive problem, as if virtually every M47/57 engine is being written off over time. Companies are offering swirl flap removal on the back of the panic. HighlandPete |

I've been in engineering long enough to appreciate if there is some issue, (however small) that is likely to come back and bite us, it will, without fail. HighlandPete |

Update from yesterday:
I got my car back yesterday and for now, the vibration is gone. The steering wheel still has some movement to it, but nothing more than just typical feedback from uneven pavement. There is no uniform frequency to the steering wheel oscillation like there was before. From what the SA said, they did a road force rebalance and put the tire with the highest value on the back...I think it was in the neighborhood of 23 but will have to check. The steering seems different now though...not bad, just different. Probably due to the wheels being rotated around on the car. I have the square setup and was planning on rotating the tires every 5k miles, but maybe that's not a good idea if it causes vibration again. On my previous E36's the dealer did not recommend rotation. Wonder if that's still the case with the F30?

My 2013 goes in tomorrow for the vibration issue, and I'm not going to be happy if the fix is stated to be a road force balance or similar, since this will do nothing for me, as it will be right back when I put my M5 reps back on.

I have just been told repeatedly BMW NA and my dealer that there is no fix and that it is normal functionality for my car.

Two days after road force balancing and while not as bad, the vibration seems to be coming back. As others have pointed out, if this is the "fix" for my vibration, it's going to come back as the tires wear or are rotated.

I smell a class action lawsuit waiting to happen, hope my F30 does not have this issue because I did not notice anything when picking it up during European delivery.
