Bolding mine.
No, the A350's RR engines are Trent XWB.
The problem RR engines on the 787 are Trent 1000.

The XWB is a variant of the 1000 but I haven't read of any A350 engine issues. Yet. But it's too early to tell.


Edit: just found this article indicating that there's been an A350 engine shutdown. It also talks about the 787 problems. https://www.godsavethepoints.com/201...engine-issues/
