My cruise control on my 2001 Kia Sportage stopped working.

You can check the fuse but I would lean more towards the set button being bad.

I am having the same problem on my 2003 kia sportage. It went off 2 weeks ago and then I got it to turn off by unplugging the battery over night but now it came back on. let me know if you get a solution that works please

usually on the end of the cruise control button(lever)..but look at transmission fluid levels add if low..overdrive is the first gear you loose when fluid levels drop..

Try checking the small switch at the top of the brake pedal. There may be two one for brake lights and one for the cruise control. To ascertain what is what, pull one wire off and see if brake lights work. If not, then the other switch controls the cruise control disconnect and engage..I you have a DC test light check to see if power is on on both side of the switch with brake pedal up. If so, depress pedal and check power on the other side there should be none, if there is the switch is defective.

I know this sounds crazy, but have you checked to see if all of your lights illuminate? My 2007 Sportage had a burned out brake light, then the cruise dtopped working also. I thought it was just getting ready to start systematically breaking down, piece by piece. As soon as I replaced the brake light, however, the cruise instantly began working again! I figured it was some strange way of Kia letting me know if I was missing a brake light. No guarantees, but it might be worth cheking out.

Well Im hoping that by telling you to check your cruise control wiring and vacuum routing for broken, unplugged wires or vacuum hoses you just might find that a simple vacuum line is in need of attention. good luck

check your brake switch mine was shot

Check the brake lighf bulbs. If even one is burnt out, it throws the sensors.
Had the same problem replaced both bulbs and now the esp light stays off and the cruise control sets.

look in side the panels in the rear of the car, on the inside next to the tell lights, there should be a red button on a switch, push the button and turn the key on if you dont hear anything then your pump is bad or the wiring to the pump went bad, known to rought on the plug
