Will this remove the carbon build-up...is it even bad to have the carbon build-up?

You COULD, but unless there is an issue with the way the car runs or excessive carbon build up, there is no reason you HAVE to. You will always get different answers on here. I work in a private shop in Burlington, ON. I would only every recommend either of those services if there is an issue to fix (I get paid hourly, not by how many services I sell). At a dealership, most tech's are paid flat rate, which means they get paid per job, which means the more jobs they "sell" the more money they are paid.

You can clean the throttle body (If it is dirty) without doing an injector flush, and add a "fuel system cleaner" to your next tank of gas or two. That will cost you $75 and do a good job cleaning up any dirt that is in your injectors. That is what I would do.

Also, a brake flush is a good idea, but if it's only a 2009, it really doesn't need to be done yet. I would wait another year or two on that one
