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.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your
pre-purchase inspection list. Back to the
