"Apparent engine failure" is a bit vague.
It would be interesting to know what failed.
Some bloody engine management system dropped a few bits and shut down?
Or did the mill blow up mechanically? This would be a bit harsh after only 4,500km

You can also quickly destroy and engine by dropping some liquid be it oil or coolant. This does not mean it's a bad engine. It might have been poor workmanship during assembly or servicing or just a hole knocked into something and not noticed in time?
You also get people who will break EVERYTHING
