i installed my uniden R3 on my model y last month. The volts showing on the radar is 15.4. When I run the same radar in my other cars, it says 13.5-14.4 volts. The radar works great in my non Tesla cars but when I put it model y, it doesn’t detect KA bands at all. Could it be that my model y is pushing more Volts out of the cigarette lighter then my other cars? Is there a fix to lower the volts in my model y? Thank you guys

- Model Y radar detector voltage
I have not looked into that. I used the original cigarette lighter cord and even purchased a aftermarket cord and it still gives me the same voltage

Where do you have your R3 Mounted?
I have the Radenso DS1, running into a usb hub with on and off switches and the hub is connected directly to the UBS C port in the Center Console. I am not currently having any issues. Have you tried checking the Radar Forums to see if anyone else is having similar issues?

No problems with running at 16V. Its within spec for the R3 per manual:
Also, I've been running the R3 in my MS with the 16V battery without issue.

If its not hardware failure or botched firmware on your R3, then I'm running out of ideas. This one's a bit of a stretch but may be worth trying:
Have you tried testing KA band performance with the R3 mounted immediately to the right of the rearview mirror? I ask because the Classic MS had a metallic layer embedded in the windshield--it was designed to reject heat (and did so very well) but came with the side effect of killing almost all RF signal transmission (e.g., toll tags wouldn't scan). The entire windshield except for the area immediately to the right of the rearview mirror had that metallic film.
My understanding is that they've moved away from the metallic film in favor of ceramic particles embedded in the windscreen (that has been the case for every M3 and MY I've seen). The ceramic, while better than the metallic film, supposedly still blocks some of the RF passing through the windshield. That's likely why Tesla recommends placing toll tags in the blue area depicted in the image below:
For what its worth, between a M3, MY, and MS, the blue area is the location I've always mounted my R3. And performance has been stellar (in line with Vortex Radar's testing) for all three vehicle types.

I have an R3 mounted above the middle of my screen with no issues. 22 MYP. Ceramic tint. I also check for firmware updates on my R3 monthly.

The power outlet (cig lighter) is actually switched, it just doesnt go off when the door is closed. This is covered in the model Y manual:
=====================================
Low Voltage Power Socket
Your Model Y has a power socket located in the center console's rear compartment.
The power socket is suitable for accessories requiring up to 12A continuous draw (16A peak).
Note
For vehicles manufactured after approximately November 2021, power inverters plugged into the low voltage power socket must support 16V DC input to function.
An additional low voltage power socket is located on the left side of the rear trunk.
Note
Power is available whenever the vehicle is considered "awake". The vehicle may be awake for many reasons. For example, when using features such as Summon, or when features such as Preconditioning, Cabin Overheat Protection, Keep Climate On, Dog Mode, Camp Mode, Sentry Mode, etc. are enabled. The vehicle is also awake whenever the low voltage battery is being charged or is in use, during HV charging, when the vehicle is communicating with the mobile app, etc. Leaving an accessory plugged in does not deplete the low voltage battery.

Yes! After a reasonable length of time it DOES power down. I'm a little concerned, though, that on a trip to my local Walmart it DIDN'T sound off for the automatic door openers like it used to. I'll have to do some testing to make sure the windshield thing isn't affecting my detector.
