hi Scotty I have a 2011 Kia Sorento every 5 to 6 days it will not start when I turn the key then after about 15 to 20 minutes it will start the Run fine until another five to six days is that the anti-theft system going bad or the alternator or starter

No. 1-1

many things can do that. so start with a pro scanning it with a dealer level scanner to check the theft system and codes and live and mode 6 data for flaws
