First, these issues share are experiences from real owners of the current 6 Series 645ci/Cic and the 650i (Both Coupe & Vert). I have owned the 645Cic and now I own the 650i (Convertible).
Issues:
iDrive software corruption:(typically) If there were issues when the buyer picked up the vehicle even with updates or re-installs iDrive issues seem to remain; different issues but issues non the less. This issue seems to affect a small population of owners (2 out of every 20) from my analysis.
[iDrive] issues are described as intermittent reboots, longer than normal boot-up, and the interface not allowing the drive to go into menu areas.
{All described issues are resolved by the latest software update}
Drive-train issues: The transmission will idle high and or jerk when gear change is required. The jerk occured mostly in SMG transmissions. Step would achieve a slight jerk but nothing uncommon with automatic gear changing.
{To resolve these issues, an update or reprogramming of the EMS/DME will be required.}
iDrive Died: The iDrive system no longer displays [Work]. The car runs but there is no interaction with iDrive.
{iDrive computer (internal) will need to be replaced and programmed.}
Key Fob Loosing Memory: There has been cases where radio, SAT and other entertainment functionality is forgotton from the last time the driver was in the car [24 hours later].
{Computer subsystem in control of the Entertainment function requires reprogramming and the issue is resolved}

Sure there are anomalies like computer fault messages, Run-Flat-Tyre becomes flat, car fluids low -- oil, power steering, window washer
, tyre pressure
-- Convertible movement failure in Texas "Must be the Heat" because I have not heard this happening anywhere else.
I believe this sums up the issues. Everything else works like it should; Pure BMW driving pleasure. I hope this helps the curious folks out.
