That's perhaps rather alarmist. It implies the earlier kompressor version of the M271 fails without warning after one fatal death rattle. IIRC from M271 failure reports there are usually ample indications from increased timing chain noise especially at start up prior to the fatal timing chain "jump" that causes the expensive engine failure? The article also fails to mention the fundamental change in timing chain design that the introduction of CGI necessitated [ greater timing accuracy] which lead to the improvement in timing chain/sprocket life??
