It is more common than people think. An easy way to tell is to see if the bumper area is blacken around the exhaust tip area.
Of course if you have a black car it's impossible to tell, but on white cars it is very obvious. I have seen this at least on 3-4 X5M around my area. It is not normal, after my injectors was replaced the bumper have remained clean no blacken area at all.
FWIW, when I had the issue the car drove quit fine, no stalling or MPG issues. However the car did felt under powered. It wasn't quit noticeable until after the new injectors were installed.
But the key point is that the dealer finally admitted to me that BMW had a batch of bad injectors.
