Nobody here can say whether there are issues with your thesis. Perhaps there is something different than usual about it.
The most common situation for students in the U.S. is that you can do what you like with the content of the thesis. You can submit the entire thing as a book, or you can divide it up and use it as several papers. This is not plagiarism, because the thesis is not viewed as "published", even though it may be available from your school's library or from services like ProQuest.
The flip side of this situation is that, when we evaluate someone's vita, we don't count the thesis as a "real" publication. So if you are pursuing an academic career, you probably should publish the results of your thesis elsewhere, to develop your vita.
In Europe, some students have many copies of their thesis professionally printed, and distribute the hard copies. I don't know whether they view this as a formal publication.
