2011 V6 1LT 700 miles: Odd, subtle, continuous noise at idle
I don't THINK this is anything to be worried about, but it just seems odd to me (I've never heard such a noise before with any vehicle I've ever owned): Ever since brand new, whenever the engine is at idle (and probably whenever the engine is running), I can hear what sounds like 'jackhammering off in the distance', or a helicopter-like propeller noise. It's continuous ... maybe at a 5-10 Hz rate. First time I noticed it (with the radio off and the windows up), I started looking around because I thought there was construction going on nearby. It's not like lifter noise from the engine. It's not metallic-sounding. It's more plastic-sounding, and I don't think it's a fan blade noise.
Anybody else notice this sound at idle?
