Its a V6. Good old BMW wants to blame it on worn belts and that I didn't bring it to their dealership for all service. This the company that markets the "ultimate driving machine"? Hyundai offers a 10 year, 100,000 mile warranty on their engines, something BWM falls short. So far, very, very unimpressed with the support and assistance I have received. They will do anything to not be the problem. Anyone know a good lawyers that may have gone to court with BMW over a hydrolocked engine?
