Known issues
From the engine's Wikipedia article, section named in each item. Links are the references attached to those sentences (archived copies where the original page is gone); where none is shown, the Wikipedia section is the source.
In the United States, some N54 engines experienced failures of the High Pressure Fuel Pump (HPFP), resulting a class action lawsuit, a voluntary recall and an extended warranty for the HPFP. Failure of the HPFP can cause the engine to suddenly stop functioning, which has caused several near-misses on highways.

The High Pressure Fuel Pump issue caused BMW North America to extend the warranty for this pump to 10 years or 120000 mi. The warranty period for the fuel injectors was also increased, to 10 years or 120000 mi.
