Manufacturers are typically as quiet as possible with regards to problems with their vehicles and most do not want to pay out big sums for repairs. Think about Toyota's recent problems. They were very quite initially about the problems with their cars. Honda Civic Hybrid owners are unhappy about the misrepresenation of fuel economy. The class action settlement gets them $200. That's peanuts compared to the increased fuel costs and premium paid for those cars. I'm sure there are many more examples like those. BMW is no different.
