My 2017 High Altitude Pat randomly makes a loud "beep-beep" noise inside the passenger compartment while driving. It's nothing mechanical, just an audible "beep-beep". I tried uploading a 2 second trimmed video from my dashcam but I'm unable to add it because it's MP4.
Any thoughts?

Any dash light turn on with it or a message in the odo window like change oil?

Willie semi-regularly (every week or two) throws the blinking TPMS light on startup, along with a couple of beeps. The tires are fine; it’s apparently a sign that the communication to the TPMS module isn’t as expected. It’s always gone out after he’s been moving for a minute or two.

So yeah - Watch for lingering dash lights while it beeps.

Nothing. And it's hard to describe the noise but maybe like 2 very short blasts of an air horn.

Yeah I've looked for something on the dash board whenever I hear it but have seen nothing.

But it's definitely not the standard chime you hear when the door is open and the key is still in, etc.

About the only way to get a sound file uploaded is to host it on another site then post a link to it.

Do all of your air vent modes operate correctly including recirculation? Maybe one of the blend door motors went really haywire making the noise?
