Engine chatter

[alee1969]

Hey everyone - apologies if this is a silly question but I have always owned 8 cylinder vehicles so wasn't sure if this is normal or not - I have a 2017 3.8 and notice that when I'm sitting idle there is a distinctive chatter - not too loud to hear from inside with windows up but is noticeable if outside the car, or when I put the windows down - with or without the air conditioning on - is this normal for this type of engine? It only has 1000 miles on it.

Believe I have read here that the GDI engines do have a bit of chatter to them particularly on start up.
Nature of the beast.

Does it sound like:

Hey batter, batter. Hey batter, batter ...​

If so, probably just a nearby little league baseball game during the summer months.

It is most likely the Direct Injection system. I had two Lexus vehicles and they had the same noise.

Oh, you mean clatter.
