Hey all. Having a loud beeping noise occur inside the cabin. 2006 4.8is

It sounds like either 4 or 6 beeps, in rapid succession "beepbeepbeepbeepbeepbeep" (all within like 1 second) and has a very "piezo"/alarm type sound to it (not the normal "chime"/ding you get with the speed warning or memo etc.) Very loud and high pitched.

Sounds like it's coming from either the passengers side, or the homelink/garage door opener console.

No warnings or other indicators. Happens completely randomly while driving or parked.

If I had to guess I would think it was the sound you get when you disconnect and airbag or some similar severity issue, but nothing is showing up to show fault anywhere.

I've already cleared/reset the memo and speed warnings, but it still happens.

Anyone ever experience anything like this?
