BMW is recalling 156,137 vehicles powered by the 6 cylinder N55 for issues with the VANOS bolts.
Quote:
BMW says it has told the National Highway Traffic Safety Administration that in rare cases, bolts holding the variable camshaft timing unit may come loose or break, causing the engine to go into a "safe mode." If the problem continues, it can lead to stalling, engine damage – and it may not start.
