New owner here....less than 500 miles on vehicle. Noticing a fluttering noise - similar to what a climate system fan might make. I only notice the noise once the car has warmed up, as it isn't noticeable when car is first booted up each day. The sound is subtle, but more noticeable due to the wonerfully quiet cabin. The sound continues whether or not climate system is on, an whether or not fan is on. Is this normal, or do I need to stop by service to have them check it?

Why spoil the quiet cabin? Being a brand new vehicle I would take it in just in case it gets worse. Get it documented now for future reference even if they tell you it's nothing.

BTW, congrats on the new wheels.

Brought it in to the Dealer - Cole Buick in Portage, MI - and they were very good (first time to their maintenence), but after a review, indicated that the noise was "normal". So, I'll live with it for now and at least it's documented.
Love this forum so far...btw, said it is a noise commonly made by the High Pressure Fuel Pump.

I would ask your dealer if you can drive another new Enclave, let it warm up and see if it also makes a fluttering noise.
