My 2019 will make a buzz noise for a few seconds after a cold start. The butterfly's that close and open the exhaust bypass is probably the issue. There was a TSB to epoxy down the butterfly. Yours sound different and it continues which I never heard of. Definitely a dealer problem.

No, it's the combobulator.

Anyway, I just started mine after sitting a week in storage and I got the same buzz noise but just for about a second. It sounds like it is the butterfly in the center of the exhaust pipe under the seats. It doesn't matter which mode it's in. I can have it in stealth mode via the settings, push the start button for five seconds without the foot on the brake to turn everything on and the actuators will move the butterflies to it positions for the mode and it will still buzz. It has been doing it for about a year. However, if the exhaust is hot, it barely does it or not at all. Since it is my weekend toy I'm not worried about.

Are you sure it isn't a frammished degronculator?
