2018 granturismo sport 15300 miles

Hello everyone looking for some imput here as I wait a few days for the dealer to look at my car.
Purchased a 2018 granturismo sport in January and have very little problems up until about 2 weeks ago. The car is making a knocking noise when it is at idle. The noise seems to get quiet after the car is warmed but sometimes the noise is pretty persistent and quite loud.
Last oil changed was 2200 miles ago and less than 2 months ago.

my 2008 also has this tick, you hear it in closed spaces especially. It gets quieter as the car warms up. almost sounds like timing chain slap. i wouldnt worry about it. ive been driving the car very hard for a week or 2 and its almost gone. give that a go.

Either one of the bolts are loose on one of the few metal braces underneath the car,

Or I think its the heat-shield metal is vibrating against the trans tunnel/transmission , when it gets warmer from the heat it expands and the vibrating stops. This happens to my car when starting from cold on cold days as well. It usually will go away within 5 -10 mins . Next time you get a chance to get the car on a lift it wouldnt hurt to then make sure all the bolts for the heat-shield and 2 cross braces are tight.

Thanks for the replies!
I took my car to the dealership I just bought it from and they told me it is being caused by the oil pump setup. They said when it gets hot outside it is normal for this noise to occur. Told me I'm hearing the teeth from the chain catching and that there is nothing to worry about.

The "there is nothing to worry about" statement I would want put in writing -

Hi.
I'm having the same issue. No alarms, but he noise is annoying. This weekend I will try to verify the bolts, thanks.
