sounds as if the position sensor in the roof control module has gone bad.

Without actually inspecting it, I recommend you take it to an authorized Hyundai Service Department and have it properly diagnosed -- impossible to tell here.

It sounds like it just needs to be reinitialized. Turn your key to the on position with motor off and hold the up/full vent button down for at least 30 seconds or until your sunroof either clicks or goes to the full vent position. That should fix your problem.

try oiling the runners

Open the shade cover to access the sunroof from inside the car. On each side of the sunroof (driver and passenger) there is a black accordian looking cosmetic molding, toward the back side of the sunroof (rear of the car) stick your finger behind it at the top and pull you will now be able to see a T25 (torx) screw you will need to slightly loosen it on each side of the car if they are not already loose then push up on the center rear of the sunroof. you may want to have someone outside of the car to tell you the proper height, when you have the proper hight set tighten the screws then replace the molding. You are done, no more noise!
