Please make sure to post to the NHTSA as they are the governmental organization that can push BMW to make a recall on this problem.
The more organizations this is reported to, the harder it will be for BMWNA to sweep this under the carpet.
This seems to be very uncommon I might add with most BMW's and specifically targeted to the GM6 transmission built in France.
There is a lot of finger pointing between dealerships and BMWNA. And no one will own up to the problem.
The good dealers are smart and get out of the problem as fast as possible.
