It's almost like air or something . Anyway kind of hard to explain. If I put it in drive i don't hear it or in reverse . In neutral and park i hear it. I don't always here it ? I can't say if it's always been there or not cause normally the radio is on or fan but since weather got nice and heat is off I happened to notice it oneday sitting in the car with radio off? What could this be? There are no warning lights on truck drives normal am oil level is good I just did the oil change ? Any thoughts?
I swear Im hearing the same thing on mine.
I came back from a drive and left the 2014 GC V6 running while I was unloading it, I swear Im hearing the same thing as you. I cant figure out where its coming from I kept thinking in the intake somewhere and its definitely not metal on metal sound its more plastic on plastic lite knocking or air popping sounding, subtle but noticable and not a steady rythem. more like XX----XXX --X ----XX --X----- XXXX --X --X- -XXX--- X --XX- -X (X's repersenting lite pop sound and dashes representing a pause .
Did you ever find out what yours was?-
