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?
