Turkey 2018

I though it was strange right after service if it was to be caused by an impact or wear. But I have no idea how much diagnostics they do in service (and how many sensors they have to monitor the health).

If it was just caused by a hidden manufacturing defect or something like that I get that it's not strange.

Well, I think that there is no way how to find some internal cracks in the material during service stop because You can't do an X-Ray or ultrasonic scan there. You have to trust Your experience. The thing is that if there is a crack in the material already initiated it will most likely result in a breakage when there is the highest load. That is when there is the highest torque (acceleration on first gear from zero speed) or when there is high torque combined with an extreme angle of the driveshaft joint (full steering at jump landing as the most extreme case).

specially with a lot of steering.

Yes, I know that on asphalt with gr.N Civic You can nearly brake the driveshaft at will...
