Roof Rack cross bars
I have a 2009. I did not think it would be any different, but I was able to remove the bolts no problem. I also have the sunroof. It does not interfere at all. Nobody has any clue as to why Hyundai puts those bolts.
I left mine out, and never had any problem. No water infiltration, wheezing sound (some people wander about the rubber strips, found no use so far for these as well), or any other problem. Seems to me you can do whatever it takes to remove them, at the risk of damaging them, you won't need them again. Some people even drilled more holes to be able to secure the cross bars more forward.
Hyundai really cheaped out with this roof rack. I had to make my own rack for my canoe. I also had to add hooks under the car, 'cause there's nothing to hook on.
