Reported Issues with the Genesis GV60

[Looney100]

I have always kept some means of boosting a dead battery in my vehicles. In the old days that was booster cables, for the last decade or so, a booster pack. For the GV60, with its known 12V issues, it is essential.

I don't think that a weekly recharge is of value. I had a battery monitor connected to my GV60 for several months, and had a couple discharges occur during that time. What I found was that they occurred abruptly. Battery was operating/recharging fine for several days or weeks, then all of a sudden, voltage drops and battery dies. A weekly recharge won't help with that situation.
Secondly, if the ICCU logic has it maintaining the battery at 12.2V (or whatever voltage is thought to be too low), then within hours of disconnecting the charger, the battery will fall to that level, and stay there for six days of the week until it's externally recharged, again.
Regular external recharging is a solution to a problem that doesn't exist with the GV60.

A NOCO jump starter is all that is necessary to start up the 12V. The things that seem essential to carry are the manual key and a small jump start pack.
That's just common sense given the obvious 12v battery issue that seems to exist across the board with Kia/Hyundai/Genesis EVs

I do understand what you are saying, However for my "own peace of mind" if I charge it once a week before I drive it I know that I at least started out the week with a "full" battery charge, vs starting out the week driving at 12.2v and wondering if it will maintain at 12.2 v or drop even further. The benefit of charging it once a week may or may not help, but for me I feel more secure in doing it this way, and after +2.5 years of ownership I have never been stuck with a dead 12v battery while travelling.

Update: After three days, service was unable to find any faults with the 12-V batter or (I assume) the ICCU. I got the vehicle back this morning. So far, I've only driven it home and gone in & out several times. No problem yet.

But I'm reading a few horrifying rumors that the 12-V battery issue happens after AC charging using a Tesla-to-J1772 adapter. I did charge using this adapter (connected to my Tesla Wall Charger) the night I got the car. It was fine driving to work in the morning and returning from work later that day, but then it was dead a few hours after that. So ... doesn't seem obviously related to the charge adapter. But... what do others think?

98% of all the charging for our 2023 GV60 has been done with a Tesla Mobile Connector charger + TeslaTap adapter.

No issues. (knocks wood)

I have the Lectron adapter.

The adapter has nothing but wires inside - no active components. It would be like saying "your television only works with one brand of extension cord." The car couldn't care less about the adapter, or even know that an adapter is being used. It just sees electricity.

 

[Yefchak]

I would like to believe that the adapter is a passive device, but somewhere I've read that there are communication signals as well. Someone wrote that Tesla and other vendors used slightly different communication protocols, leading to a problem. Seems odd, but I'm suspicious...

 

[ideutsch]

The adapter does nothing but connect the legs of power, ground, and signal wires. Level 2 chargers are also very simple. All the power conversion occurs within the vehicle.

Essentially, a charge port adapter is not going to cause issues with the 12v battery.

It does seem unlikely, but I will add that the Lectron adapter did not work with our car. That’s what I tried first, then replaced it with the Tesla Tap.

Here is an update. My car is still in the shop it will be 4 weeks Tuesday with no ETA on the back ordered replacement part (ICCU). I started a collateral swap and put a deposit on a new one that will be here 3/26!! Same color and everything except it is an Advance not a Performance which is what I originally wanted anyway.

 

[Yefchak]

New question from me here... What is the current version of the over-the-air software update (at least for the USA)? My car says it has version JW-USA-ccIC.001.010.240717. But it also keeps saying "Update was unsuccessful. Please try again when restarting the vehicle later." I'm not sure if "try again" refers to anything I can do proactively, but I have to dismiss this message each time before I drive. The car was purchased (and presumably upgraded to the latest versions) on March 15th, 2025.

 

[noremacnova]

It's very possible that your 2025 model has a different software schedule than my 2024, but the latest version as of this posting date for the 2024 model year USA vehicle is JW.USA.ccIC.001.009.240923

 

[wildt]

I would get on the wait list for the part. It is the ICCU t bust was recalled on the 23-24 models. I am guessing they didn’t start replacing them while building the 2025. Yeah I bought a charger too. The concern with me taking it back is it eventually causes the car to drop in speed suddenly. You will hear a pop the you will go from 60mph to 25mph.

This is a serious safety issue and should be reported to the NHTSA. It only takes 5min to complete the form.

Update: the car had been find after that first failure which occurred 23 hours after delivery a month ago... until this morning! The 12-V batter was nearly dead this morning. I discovered this when I was unable to close the charging port door. I had charged the car to 80% last night, which worked fine as far as I know. I even got a message on my phone around 4 a.m. saying charging was complete. So somehow the 12-V battery died between 4 a.m. and 9 a.m. It wasn't completely dead, actually, because the little flashing red light above the dash (security system, I suppose) was still working.

I connected my nice new 12-V battery charger (NOCO GB20) and the car came on right way. So that's good at least...

I called my local Genesis dealership, hoping to get some advice on what I should do next. (The car was purchased at a different dealership 30 miles away, because the local on in San Jose doesn't sell the GV60!) The told me I could bring the car in and the could "squeeze me in on May 12th." That's nearly a month from now, and they didn't even offer a loaner car! Isn't Genesis supposed to have better service than this?

I called the national Genesis customer relations number. I now have a "case number" and have been told to expect a call back within two days.

What should I do? The car seems to be working again, but of course that's been the case every day until it failed. I was quite surprised to NOT see the 12-V charging lamp above the dashboard light up. Surely the 12-V batter should be charging when I got the car started this morning, right? And the energy usage display on the console continues to show 0% for "battery care." None of this makes any sense to me.

You mentioned that the local dealer does not sell the GV60, are they authorized to sell and service any electric vehicles? If not, I would reach out to the dealership you purchased from. Your experience with Genesis service though is unfortunately not a surprise.

The orange light on the dash will only illuminate while the 12V battery is being charged while the vehicle is off. It’s really just indicating that the high voltage system is engaged. The “battery care” you see in the electricity usage screen in the dash is not for 12V charging. That’s to show how much electricity is being used for things like conditioning the battery. It’s described in the owners manual page I’ve attached.

 

[Yefchak]

Ah, OK, thank. And yes, the local deal does service GV60s, just not sell them. (Yeah, weird...) Actually another guy who works in my building has been taking his GV60 there for nearly three years and has never even heard of these 12-V battery issues.

 

[Nicoleabright1]

When you go, have them do a full evaluation on the ICCU. I have a 2025 as well and after only a month, it was permanently placed at the dealership awaiting the part that had no ETA. Since then, I have heard that parts are coming in pretty regularly now. I recommend getting a 12 V battery monitor Bluetooth of course so you can keep track of your 12 V battery and also a quick charger for your funk.

Update -- the car was dead again when I tried to leave work. This time when I tried to start with my little battery, the horn honked and I got a battery warning on the console. I don't recall the exact wording, but basically "battery has failed, pull over and stop driving." I assume this means things are really dead now. I had just set up a service appointment (for April 28, which is 12 days from now!). I guess tomorrow morning I will need to have the car towed to that dealer, which is 40 miles away. This is very frustrating. Surely they will give me a loaner, right?

My dealership was out of loaners so they rented me a car. It is a part of the concierge services. I had a rental at their expense for 6 weeks. Here is my story
