2017 base Giulia, ~500 miles, no after-market gear.

I've had her for few weeks now, and she just started making a strange, random buzz/alarm with no corresponding visuals. The sound is different from all of the expected audible alerts (seat belt, door open, key fob removed, parking sensors, forward and reverse obstacle detection, etc.), and sounds like an old-school door-open alarm. It's not a beep or ding, it's a constant tone, and the volume of the tone correlates to the volume of the radio (i.e., if the radio if turned down, the tone is soft, and when the radio is loud, so is the tone). It sometime goes for just a second or two, and sometimes several seconds. It happens most often when my auto-stop engages, but has also happened while driving at slow speeds in city traffic. It happens most in stop-and-go traffic.

This started when I was literally pulling out of my dealer's service department after having my front license-plate bracket installed (the bracket requires drilling into the front bumper, covering the driver's side tow hook). The front sensors do not seem to be obstructed.

At first I thought either I had a door that was mostly, but not fully latched, or that it was some kind of tailgating/obstacle detection of some kind, but it sometimes happens when there aren't any cars that are particularly close, and the alarm is different from any of the ones I mentioned above.

Is this some kind of safety feature that I hadn't encountered before, or is something wrong? Thoughts?

Have you taken it back to the serving dealer for correction. Appears to have started after that visit correct.

and if it happens intermittently, take a video of it on your phone, because it may not happen when you bring it into your dealer, or they may deny that they saw it. good luck!

Is it just the front parking sensor, with the visual sensor turned-off? You can set it to audio-only.
My ParkSense was set to sound only (not sure how, because I'm certain it was set to sound+visual), so I'll see if that's the answer.

The tone is different from the regular parking sensor, which beeps with increasing urgency, culminating in a solid tone.

I'll keep an eye on it, and update if I learn anything new.

It is almost certainly parksense with the new plate obstructing the sensor. No distance = solid tone.

Now that I have the visuals turned on for ParkSense, I can verify that this is certainly the issue. I have another service appointment in a couple weeks. Will definitely have them take care of it at that time. Thanks for all the input!

I hope aligning the plate is all it takes. If they pranged the harness during the drilling job it could be a long wait. :(

Update: I had my service appointment, and they didn't fix it. The note on the service ticket said:

"1448 SCANNED VEHICLE NO CODES SET, ROAD TESTED AND ALL WORKING CORRECT AT THIS TIME, FRONT PLATE BRACKET MOUNTED IN CORRECT LOCATION. DID FIND EXCESSIVE BUGS SMASHED ON FRONT OF VEHICLE POSSIBLE CAUSE OF SENSOR INTERFERENCE"

Note, it does not happen all the time, and only at very low, or no speed.

I've linked to some pix of the bracket placement and a video of me driving in slow-and-go traffic. The alarm sounds soft here because the stereo is muted. When audio is playing, the alarm is much louder/more annoying.

Hello I removed the holder from the license plate and attached it directly to the bumper
No more buzz

How did you attach it to the bumper? Did you drill new holes, or some other clever solution? I'm not about to drill new holes in my bumper.

Ah, I see. Plates in the States are different from yours. I don't think that's an option for mine.

sorry I forgot this detail !
here in Portugal we have had this problem and the solution in the costumer car is to slightly lift the bracket up

Ugh! But glad you got it solved. Punching the bumper is just a shame but maybe what you gotta do. Sure enough, tucking it in that little bit was enough to clam the sensor down. They must have a really good arc towards the vertical plane. That can't be more than 15 degrees difference if that. Or maybe it was too close.
