    Smile 2013 Optima EX

    Hi everyone. I go by Joecorvair. My wife's car is the Kia. It has almost 150k miles and luckily has been a very good reliable car and passed the engine recall test. Recently it has been making a short growl / snort noise when accelerating from a stop. I listened to it with my wife pressing the gas with the brake and it sounded like was in the intake area. I could feel a vibration that felt like the sound was in the silencer in the intake hose. I took the hose off and shook it and nothing. Then I took off the air filter cover and it rattled when I shook it. The carbon looking filter that says "do not remove" was a little loose so I put some rubber sealant in the corners (not on the air filter seal area) and after it dried put it back together and voila no noise!
    Hope this helps someone. I saw a forum question from earlier this month that sounded like the same issue but I could not post because I'm new here.

    Hi Joecorvair, welcome aboard to the Optima Forums!

    Wow that is a a lot of mile for the 2013 Optima EX.

    Glad to hear it's running like a champ, and thanks for the tip.

    Thank you for the heads up, I posted earlier on what seems might be the same thing. I will check on it this week end!

    Well, I took my whole intake apart and cleaned the throttle body while I was at it. My system had no carbon filter in the air cleaner box and nothing ratteling. Everything looked great, put it back tougether and still have that snorting noise at initial throttle and again it is more pronounced when the AC is on. Last week I was in the Home Depot parking lot and I heard another LX making the same noise?
