You are welcome.While Hyundai did seem to cheap out in some parts that boggle the mind (like the door handle assembly) they also over engineered some aspects as well. The Tau engine is a perfect example of that. And it appears you may have found another.
Thanks for the write up. Definitely good to know.
Thank you. I will look it up the TSB on the Hyundai service website.There is a service bulletin out about this issue. Don't know the number. Dealer might help you.
It recommends wire splicing and a slight re-routing of the wire bundle.
There's about 9 wires in the bundle. Plus the optic cable for the camera.
I assume your reverse camera still works?
My car had 7 broken wires IIRC and a partially damaged optic cable. Still worked!
Don't wait too long to repair. You don't want to deal with a broken optic cable.
Good luck
I found the TSB related to the trunk wiring harness. This TSB helps big time and clarify what went wrong with my taillight.There is a service bulletin out about this issue. Don't know the number. Dealer might help you.

Today my rear right side inner lights went off, I figured out it was a wiring issue because it’d be lit back on once my trunk was open. Excuse my ignorance but if the trunk is open, technically means these wires should still be somewhat intact? Any advice on how to fix this?Today I fixed three broken inner taillight wires as per the TSB and now my inner taillight work perfectly; brake lights and all.
My advice would be for anyone with a 2015 or 2016 Genesis model is to check to see if the right side inner taillight harness has been relocated to prevent the wires from being too stressed and breaking. Either check yourself by pulling the trunk trim or have a dealership check it before the wires break. The car does not give a bulb out warning for the inner taillight if it is out. This repair job could be expensive out of warranty if a mechanic does the job, especially if the wires are broken.
My broken inner taillight wires.

Inner taillight wires repaired. I used aluminum foil to protect the good wires when I applied heat for the shrink wrap tubing. I relocated the wire harness as specified by the TSB and used cloth electrical tape to protect the harness from chaffing when the trunk lid moves.

My advice would be to just inspect the wiring harness by removing the trunk trim and see if a wire is damaged. A frayed wire is probably touching bare metal or another frayed wire when the trunk is closed which shorts out the light and maybe the damaged wires do not contact anything when the trunk is open.Today my rear right side inner lights went off, I figured out it was a wiring issue because it’d be lit back on once my trunk was open.

Appreciate the response man! I took apart the trunk trim and it looked like everything was fine, didn’t see any exposed frayed wires. Except this time after taking it apart, and the trunk still being open the light wasn’t on at all, whereas last night if I opened the trunk the light would be back on, and when I closed it the light would flicker on and off on its way down.My advice would be to just inspect the wiring harness by removing the trunk trim and see if a wire is damaged.

This is only speculative; the only way to know for sure is to visually inspect the wire harness or probe the wires for any shorts.
I had to remove a lot of the tape to find my broken wires. At first I was thinking that my wires was good(and the problem was more serious) until I kept removing tape and then I found the damaged wires. Even after I found the wires I used a continuity tester to make sure the wire was not broken in other location farther down the harness. I would also relocate your wiring harness to prevent the issue from happen again when you repair the wires.Appreciate the response man!

So like you advised there’s most likely a short. I’ll probe the wires to see. Last question is, if I find a short, should I just cut up all the electrical tape till I find the area that’s causing the problem or?? I have friends at an audio shop who helped fix my electronic exhaust cutouts and I’m wondering if they could help or just go somewhere professional? Any advice on this?
Ohhh man do I feel like an idiot… I had just recently changed my rear emblem since it was getting worn down, I was a bit in a rush so I didn’t bother to plug the holes in the trunk once the emblem was removed. I was spraying goo-gone with open holes and looking now I see the wiring that’s directly in front of the holes for the emblem.. I didn’t bother to flash a light inside the hole but also assumed they wouldn’t have put open wiring connectors directly behind the holes, wow. I feel like an idiot, lesson learned. I guess imma try to clean it out and hope for the best, otherwise I have no idea what to do to be honest.I had to remove a lot of the tape to find my broken wires.

Here is how much tape I removed to find my broken wires.

Try cleaning the wire harness connectors pins with electrical contact cleaner. We all make mistakes when trying to do work our cars from time to time; it is part of DIY. Make a mistake and learn from it.Ohhh man do I feel like an idiot… I had just recently changed my rear emblem since it was getting worn down, I was a bit in a rush so I didn’t bother to plug the holes in the trunk once the emblem was removed.
