I don't ride on any wheels that I haven't built myself or have serviced by checking the trueness, tension, and ensuring they have been properly stress relieved.
Machine built wheels can be great as long as they get checked before you use them and after that they should be trouble free...it is worth it to bring them to a decent wheelbuilder / technician to check them over.
I have worked on a lot of bikes (and these are nice $$$ bikes) where this has not been done and in some cases the wheel had to be completely rebuilt after they de-tensioned under load.
