I was driving at highway speeds and there was a sudden loud noise from the engine compartment and a loss of power resulting in my car becoming a hazard on the road. There were no warning lights or indicators that there was an issue. I was able to get pulled off safely and arranged for a tow to the local dealership. The dealership diagnosed the problem as a failed rod bearing which would result in the need for a new engine. They also stated that this is a problem they see often with the 4.4l engine. It seems that if this is a known issue, BMW should have issued a recall.
