When you hear the beep is anything displayed on the DIC?

Nothing is displayed. It's not the same tone as if your seat belt isn't buckled, it's like a quick beep usually happens 1-3 times at random times when driving.

There are many ways to customize how the blind spot warning, collision warning, pedestrian warning, etc are displayed and heard. For example I have front collision system partially enabled so that I get a beep when detected, but active braking is turned off. Sometimes when going over a speed bump or hitting a pot hole it will quickly beep at me even though nobody is in front of me. I also know that when the windshield gets dirty enough it will affect how well the sensor works. Everything is radar and lidar based now so false warnings/beeps can occur when nothing is actually wrong. There are sensors in the windshield, side view mirrors and rear bumper.

I've had it happen occasionally too and am not sure what it was for either.

I'm aware of the alerts they make but it's different from the safety features alert tone. I wish I could record the sound.

I'm just curious about what the sound is for, not something I would take to the dealer because I don't know how I would explain it. Everything in the car is working normally.

First time I noticed this was during a very heavy rain. Nothing on the Dash Info Center though.

The car I had prior to this would do a similar noise with no explanation, which turned out to be its warning that the outside conditions might lead to snow or ice. But this car has the heads up display for that message, and it shows up every time I drive, so can't be that.

im just taking a wild guess that it could be the outside temperature

No, it still makes a sound even if the car is parked
Raji, do you notice if it happens when you have something on the passenger seat or on the seat floor? This only happened to me once and I'll have my TB for a year in two weeks. But there were 2 potential causes, it was raining cats and dogs AND I had bags of Christmas gifts on the passenger seat floor. I've read about other GM models doing this random beep for those two things.

I have a car seat cover installed on it and I keep my hat on the seat, nothing on the floor other than weathertech mats

I never have anything in the seat or on the floor ... the one time that I heard the beeps I did, plus it was pouring rain. Good luck.

You wrote it makes the beep even when parked. When you say parked, is the engine running? Or are you saying it makes this beep even with the power off.
You say nothing gets displayed on the DIC. How about in the area above the DIC where various icons get displayed such as the lane departure is on or off?
Do you notice that this beep happens when you are behind another vehicle or close to a wall (such as when parked in the garage).
A longshot but possible is the remote sensor. Try using your other set of keys. If it eliminates the beep, then the "bad" remote needs battery replacement or is a bad one.
If you do a Google search on "random beep sound when car is parked, Chevrolet" you will find that this was a problem a while ago with the Chevrolet Malibu and Equinox, which I could not find what the solution was other than Chevrolet said there would be a fix but not retroactive and would be a long time before it could be fixed on future production.

The engine is running, no icons are displayed, lane departure is on, auto-stop is off. It's not the main problem for me but ill try to google it, I don't mind the beep but was curious if others experience this. Thanks

You mention no icons but that your lane departure is on. This should be displaying an icon in the upper portion of the dash, above the DIC, same if your auto-stop is off. But regardless I would try putting everything back to factory settins (I would turn lane departure off, and leave auto stop on) and see if it goes away. This beep may be just a reminder that you have departure on, autostop off.
