Welcome!

It can go either way depending on how it was cared for. The key to put the odds in your favor is if you found an X5 that came with lots of history and no major issues were found in a pre purchase inspection. If you bought a well maintained vehicle you could be fine for another 25,000 miles or more. Somewhere around 100,000 miles the suspension may need some work.
