As miro_o says, it gets plastered over everything that Trek do so naturally some of it'll be alright, some of it utter shit.
I got one of the Race XXXLite carbon stems at a steal a few years ago (I work in a Trek dealership) and other than a rather low quality look and feel to the faceplate - it did it's job but on a stem with an rrp of around £150, I'd expect something, nicer - I had very little to complain about.
On the other hand, we had a £7k Project One Madone that had a set of the carbon wheels (can't remember what ones exactly but suffice to say, they were high high end) and they were shocking. The wheel had zero stiffness to it, you could wobble the rim probably a full inch side to side and the spokes were properly tensioned.
I tend to think that most of the stuff that comes out of Trek/Bontrager is a) a bit dull and b) doesn't really live up to the image of quality and innovation/great design that a lot of people seem to have for the brand so it's not a brand I lust after myself but what I will say of them is that they seem pretty good at honouring warranty claims (I'm sure the P1 Madone owner ended up with a set of very nice third party wheels when Trek couldn't sort the Bonty ones).
