Yes, there can always be cased cited where such and such a bike broke and folks tend to then make a generalisation. Unless such events have a recoded history of happening frequently, it's heresay.
Many cyclists I've come across dislike Treks - I've been told my Madone is "the commodore of the peloton" by a fellow club member riding a Pegoretti...it is personal preference, but I personally know of quite a few Colnago, Pinnarello and other so called "exotic frames" failing in less than 10 years, and what happens then? You buy a new one. Trek on the other hand provide a new frame.
I'd be interested to hear why anyone might dislike a Trek 9.9 SSL if they ride one!
