2014 Kia Optima Ex
Hi everyone. I am getting a strange chugging sound from my left front tire area. Tires are 3 months old and at proper pressure. I added a little air just to see if the noise would go away and it did for a few miles and then returned. The brake pads are new but the rotors are not. I thought something might be dirty so i blasted the wheel area with the high power hose at the car wash and the sound went away for like a week and a half.. Happened again. Blasted it with the hose went away for another week and came back. I am stumped... Please help. The sound when it happens is a cha cha cha cha cha.. If it is a wheel bearing would it go away when blasted with the hose? The only thing that helps is inflating the tire over recommended pressure( I know not a great thing to do)and blasting it with a pressure washer...Dirty rotor, bad belt in tire? I am having it looked at in a couple days but would appreciate any thoughts... Thanks!
