How to disable VESS (Virtual Engine Sound System) on 2020 (US)

There is a slight gap right below the trunk opening latch and radiator in 2020 Niro EV. If look into this space, you will find VESS cable. Use a steel straw to push the cable lock which is facing towards radiator until you hear a click sound. that basically unlocks the cable. You can pull the cable right up to disconnect VESS. This took 2 minutes for me to disconnect. hope this helps.
Below is the link to purchase steel straw from Amazon. its $2.

Anyone know what he is talking about? I can't figure it out.
 
I have a 2020 EX Premium. I "think" I see the connector but want to be sure. I made a quick video as to what I think I need to unplug. Is this correct?


It is the shown connector. You can use the straw kri mentioned above to unlatch it. I couldn't pull it up with the straw, but I was able to reach my hand in there and pull it up.
 
I just bought a 2022 Kia Niro EV. The reverse sound was like a dump truck in the driveway. My wife said to turn it off. Ok. I decided the disconnect approach was my best option. I followed the instructions on the post prior to remove the front bumper, with the proper tab removal tools (Amazon), and I got to the last step which was to removed the bumper. I elected to try to remove one side only and put my hand in and remove the connector. With a bit of courage and a quick but firm pull, I successfully parted the right side of the bumper from the vehicle with only a tiny, tiny plastic piece as collateral damage. I pulled the VESS connector off with a pair of needle nosed pliers and carefully re-assembled the bumper and bottom separator. It disabled the sound, and with no warning light (so far). I considered wiring in a switch, but I would have had to chase down a wiring diagram, and a lot more work. I've decided that a quick tap on the horn when I'm backing in a parking lot will do just fine as an alternative the the overly loud and obnoxious reverse chime.
 
I have a 22 Niro and like many are not happy with reverse noise. People here have stated they have successfully disconnected the connector via accessing in the gap under the hood, apparently either with a metal straw, a long screwdriver, or even their hands. I have tried to disconnect but so far have not had success...I am having trouble unlocking the connector with my hand or tools. I have torn up my hand pretty well reaching under there. Just to confirm, where is this tab on the connector that must be pressed? It is facing away from front of car I assume? Is it pretty low down on the connector? How much force is needed and how wide is this tab? Frustrated...it is seems like others didn't have any problems, at least not that they mentioned. My hands are pretty large...Thanks.
 
On a FB Niro group that I'm part of, one new US 2022 owner claimed that the reverse sound didn't seem that loud. I'm just curious if KIA has indeed lowered the volume for 2022. Could any US 2022 owners compare the volume to the 2020 model in this video? I know it's difficult to really compare to a video, but in the video the horn is honked in the middle to give some reference for relative volumes.

Would say just as loud for 2022.
 
Success! Just using my fingers I was able to unlock via pressure on top part of connector, hear click, pull up, and remove. No more bothering neighbors or family members in early morning.

I tried looking for the wire on my 2022 Niro EV and can’t seem to locate it. Any chance you could take some better pictures of the location or maybe FaceTime to help me out? I looked at the video above and can’t seem to find a wire that looks the same. Tired of listening to that crap lol.

Thanks

Disregard I figured it out. What helped me was disconnecting the radiator bolts and prying it away from the front plastic “frame”. Easily fit my hand in there after that. Also removed the hood latch assembly. I was looking downward in the radiator and not seeing the wire. Realized it was forward of the radiator reaching towards the Kia logo on the front bumper, in the 1” gap.

Pic of the radiator bolt to remove, one on each side.

I put in a fuse bypass switch to enable/disable the backup "chime" but I wonder if anyone knows what the other function on that fuse, BATT_COOL_EXV, does. Is it a warning, or is it needed to turn on battery cooling when needed, or something else? Anyone have a shop manual that sheds light on this?

I'm interested in this too.

That controls the cooling fan for the 64kWh battery. I know it kicks in when fast charging on warmer days at high speed (it is noisy). I do not know if it kicks in more quietly under ordinary operation

Can confirm 2020 US Niro EV EX Prem is same volume as 2022 US Niro EV EX. We have both.
 
It is too bad the battery cooling electronic expansion valve is on the same fuse circuit. That would make it easy to disable. I pulled it out for a while to try it and had no warning lights, but seems problematic if fast charging or running it hard on a warm day.

Seems it would not be too hard to find the wire to the device and just pull it instead of popping off the bumper...
I found a fuse bypass switch online that allows me to turn the VESS off via the fuse when the noise is a nuisance (like backing into or out of my garage), but then turn it back on in all other situations! It’s been working well for me!
