2005 BMW 6 SERIES User Comment / Complaint

I bought a new 2005 bmw 645i.and it had computer problems. the dealer said the manufacturer usually fixed problems in 60-90 days. it has been 18 months and the on board computer has problems with the entertainment, and bluetooth. the computer continues to play cd's after the engine is shut off. the dealer ignored the problem for months until i said the car would need to be bought under the "lemon law'. they will not replace the vehicle because they now say all 650 and 645 models have similar problems and they cannot guarantee another vehicle would perform without problems. the dealer and bmw northamerica are aware of the problem.
