There are sever possibilities to the horn not blowing consistently. The horn relay or horn button are the most common followed by a loose wiring connection or a defective horn.
you should lock driver door with key then unlock with key , that should stop that issue.
if your horn wont go off its a short to power or faulty conector

ok, you will need a few items. List of materials: White paint paint brush a sportage a friend with a drivers liscense stopwatch First use the white paint to make a start and finish line where ever you want to do the timing. Second, get your friend to drive the sportage up to the start line. once your friend is at the start line say "GO" and simultaniously start your stop watch. When your friend crosses the finish line press stop on your stop watch. record the time on the stop watch as your "sportage time"
