Strange noise when my new 2021 Model S locks and unlocks

Take it to service center. They should fix it. Most of the Mobil techs who come out are clueless. This one time this mobile service guy came and told me oh I do stuff for Tesla on side. I can go sound barriers on your doors for you for 200bucks
OP, did you ever figure out what was causing the noise? My '20 MSLR+ is making the same sound that you described. I've never heard a moose call, but like you, I would imagine it sounds just like when I lock and unlock my doors! Sounds like a rear door, or hatch mechanism. I'm out of warranty so I'd like to try and resolve it myself.

Got an audio clip of the sound? I've found the handles can dry out a tad and get a little squeaky at times. Some silicon lubricant spray around the edges fixes it.
Thanks for the reply. Here is a link to the video I took with the sound. It's funny because it sounds exactly as the OP described.

Can you get out of the car and figure out which lock/handle is the origin of the sound?
I didn't think that pre-facelift Model S cars has the boom box functionality to change lock sounds. I'll certainly check the car when I get home to investigate. That would certainly be a simple resolution!

So it's definitely coming from the hatch. Seems to be the lock mechanism. My car is an early 2020 build and does not have the boom box feature, so it's not an adjustable lock sound. I tried a little lube in the hatch lock mechanism with no luck. I suppose I'll make an appt with Tesla. I'll keep this thread updated with what they say in case anyone else has a similar issue.
I replaced the cinch mechanism (a Mercedes part) and the noise went away for a week. Now it's back all of a sudden! I'll have to remove the hatch plastics again and see what else it could be. I'm baffled.
Well, after several hours of troubleshooting and multiple rounds of taking down and putting up the hatch trim pieces, I found the root cause of the loud sound from the hatch. I climbed into the hatch and had one of my children open it and close it until I could pinpoint the exact source of the sound. It turns out the sound triggered by the unlocking of the hatch was coming from a speaker. I took the plastics off yet again and isolated the specific speaker, while at the same time noticing that the connectors for the speaker and the hatch light are all the same. I looked at the light and it was not illuminated despite being connected. I thought possibly that the connectors had been mixed up and the light connector was plugged into a speaker which was causing the noise when the vehicle was unlocked as the light connector was powered. Sure enough I switched the connectors from the speaker making the noise to the light and the light popped on and the sound completely went away.
Tesla had previously attempted (and failed) to resolve some water that was getting into the hatch and dripping out of the power hatch trim piece. When they put everything back together they must have switched those wires. The situation cost me 6 hours of my life, and $75 for a part that didn't fix the problem, but I am beyond relieved and excited I was able to determine the cause of the noise and get it fixed for good.
