Reported Issues with the Genesis GV60

[asterixs]

For those regularly charging their GV60's 12V battery with an external charger, what is the concern you're looking to address?

Isn't observation of the orange light enough to assure you that the battery voltage is being maintained? Have you had some recurring issue that has lead you to believe the battery is not being properly charged?

I'm not sure how big chargers the 12v, if it's DC to DC or it supplies AC to DC. I charged 12v full earlier this week, I noticed Orange light doesn't come as often as I had seen in the past. It does come when I play video when fully stopped for extended period, kind of 30min or so.

Most of my trips are local, I hardly clock 15miles on a 45min drive. So, I think charging 12v once in a month would maintain the longevity and avoid some unpleasant surprise. I'm keeping a jump battery irrespective.

I think with some of the members on the forum and from what we have seen on YouTube with the Ioniq 5 12V issues, there is a concern of a dead 12v battery. For example, if I externally charge the battery at the beginning of the month to +13v and then during the month the Orange Light would come on to charge the battery. However by the end of the month my battery voltage is down to 12.2v. Someone on the forum the other day mentioned his car was in storage or unused for 3 months and the 12v battery was dead. I assume that during that time the Orange Light was coming on to charge the battery, but it appears after a period of time it was not able to maintain enough of a charge of the 12v battery to start the car.

From my experience with a few dead batteries soon after delivery, subsequent use of a battery monitor, and what I've seen online, 12V issues seem to be acute - the system being ~13V at one point, the (DCC, I'm pretty sure) inverter not coming on to top up the battery when it should, and having a low battery condition shortly after. Furthermore, it appears to be related to some excessive draw, rather than slow recharging. It seems the system checks the battery at some interval, and if the drain occurs in between checks/charges the battery gets too low and since the recharging system runs on 12V, it can't work to save itself.

It does not appear to be gradual - as if the system was somehow not able to keep up and lost some amount each day until it got too low. In this sort of scenario, a monthly external top-up would be of little value, unless you happen to be charging on one of the days the system failed.


Someone chime in if they've had a different experience, but what has been posted to the board seems almost exclusively to be issues in the early days/weeks of ownership. In my case I had 3 or so dead batteries within my first month of ownership and nothing in the ten months since.

I'm curious to hear the details, but I suspect the individual who had the battery drain while the car was not in use did not have it plugged in as recommended in the manual.

Unlike an ICE vehicle, the 12V system in the GV60 charges both while being driven and periodically when off. If things are working correctly, the length of your drives should be irrelevant to 12V battery charge maintenance.

I've attached a few screen caps from my battery monitor to illustrate.
The July one was (I believe) my least dead battery. You can see that the battery went from 13V to 8V in just six hours. No trickle charger would help there.

Here's the narrative on the screen cap from yesterday - a particularly interesting one given the activity during the day.

• The battery got down to 12.65V before the system automatically topped it up just after midnight. It delivered voltage of ~14.7V while charging and brought the battery up to 12.95V when it was done.
• The ups and downs from 6:30-7:00 are while I was driving and should probably be ignored as they were likely driven by different systems going on and off while driving. I arrived at the office and plugged the car in, but scheduled a delayed charge.
• The car begins to charge the HV battery just before 9AM. The 12V battery reaches a low of 12.6V before it also begins charging simultaneously at 9AM. Charging voltage goes from 14.6V to 14.4V before stopping just before 11AM.
• The HV battery continues charging until about 12:15, where we see that dip in voltage, then is flat at 12.9V until 1:30 when I leave the office. It rests at 12.8V while at home for a short while, dips down to 12.3V as I leave the trunk open while loading up the car.
• Again, reported voltage swings up and down while driving ~2:45- 3:15.
• There are some ups and downs at 12.3V to 12.6V as I leave the trunk open while unloading the car. Then remains about 12.8V for about an hour while the car is shut off.
• Voltage goes from 14.4 to 14.1V from 5-8 PM while I'm using V2L. Then is at 13.7 on the drive back home, then remains at 12.9V for the rest of the night while shut off.

Over the course of the day, we see the battery charging spontaneously between 12-1AM, while charging the HV battery 9 - 11AM, while V2L is in use 5-8PM, and while driving ~9-9:30.

Finally, a 15 day graph (the longest period available). The car charges the battery whenever it hits 12.6V. Whenever the voltage appears lower, the car is in use. I wonder if that is a sign of a weak battery - from the three discharges it has suffered.

Does anyone see anything here that would indicate that a monthly trickle charge would be beneficial?

Thank you for your detail summary of what happened to the 12V battery.

12v battery issues are by no means exclusive to Genesis. Virtually every one of the five EVs I’ve owned had many threads, within their forums, on 12v battery issues. Tesla was probably the worst for this issue. The Genesis is actually the first EV I’ve owned that tells me the HV battery is charging the 12v battery.

With that said, it’s still amazes me that this remains such an issue.

I love going out to my garage and seeing the orange glow light going - it means it is charging my 12v! Just saw it this morning!

It certainly isn't intuitive, and involves combining a couple different features/section of the app.
In the Canadian app:

1. Go into 'schedule'. Use the slider to turn Schedule on.
2. Select Schedule 1 or 2, then enable Scheduled Charge
3. Set the day and time you want to depart.
4. Make sure you select 'Apply' or 'Save' before hitting the back arrow on any changes you make anywhere in the app, or it will just ignore your recent input - without warning.
5. Go back to the main 'Schedule" screen.
6. Use the slider to turn on 'Intelligent Charge'. You'll then need to input your 'Off-peak hours'.
7. You want to set this so your off-peak period ends when you want the car to be ready, so if you're leaving at 8AM, select that as the end time.
8. Do some math to estimate how much time you're going to need to charge, and set the start of your off-peak period so that the total time within the window just barely covers what you'll need - maybe is even a hair less. For example, if you need 3 hours, set off-peak for 5 - 8 AM.
9. Select 'Prioritize off-peak charging', this will cause the car to charge mostly during the time you specified, but gives it permission to start earlier, if needed, to complete charging by 8AM. If you tell it to charge ONLY during the period, you'll get your three hours of charging, and that will be it, even if that doesn't get you to your desired charge level at departure.
10. Go to 'Target state of charge', and select the percentage you want the battery to be at when you depart. 100%, if you want to leave with a full battery.
11. ALWAYS HIT SAVE/APPLY WHENEVER IT APPEARS ON ANY PAGE THAT YOU'VE MADE A CHANGE. Otherwise, you've just wasted your time and the car won't be ready.

There you go, 11 simple steps.

A small change to my instructions based on some recent experience doing this.

I assumed that the car would ensure that it had reached the desired SOC by the end of the off-peak period, but this does not appear to be the case - at least if you don't indicate a departure time - so, you may want to set the off-peak window to be large enough to cover the entire duration needed for charging.

We also had issues with an otherwise great Ioniq EV (mostly sold in California). A few days ago I was helping a friend investigate a new Ioniq 5, (at this less than pleasant Hyundai dealership), every car they tried to show us were dead from 12v drain - 7 in all. So embarrassing for the rep and seems so at odds with the otherwise amazing technology in these cars.

Initially we had 12v batt issues for the 1st few weeks when we took delivery (less than 25% charge level that required a trickle charger (the big batt was NOT charging the 12v for some mysterious reason even when the car was at 80% charge). Somehow it settled out and no further issue with the 12v.

"...less than pleasant Hyundai dealership."
Isn't that redundant?

What I can't figure out is why some of us have this problem and others don't. I have had my GV60 for 5 months and this has not happened even once. I do regularly see the orange light on the dash when I am in and out of my garage (I have to walk through my garage to get to my home office so I do it a lot).

Hi Steve, I think the issue could be a combination of the cars sitting on the ship/dock/lots for a long time with perhaps a very low Lithium batt for shipping/storing (remember the container ship full of Porsche/Audi cars burning/sinking?) that would not charge the 12v and/or issues with software/firmware that won’t charge the 12v correctly. We’re glad ours resolved with no further issues.

Apologies. But can someone please remind me what two buttons to push and hold in order to reset the infotainment system?

I did the update yesterday, and it instantaneously bricked the system. I restarted the car and it came back to life, except for the radio. I can access media and other parts of the infotainment system, including navigation and maps, but neither the physical radio button nor the touch screen radio button work.

TIA

If I recall correctly, you also are supposed to be in accessory mode (start car without foot on the brake).

Thanks all... I went to the gym, and when I got back in the car, it had corrected itself.
I'm not wholly fond of being a beta tester...

The GV70 has a more vertically raked rear window.
But I think it was completely stupid that the GV60 doesn't have a rear wiper.

I agree especially if it snows where you live.

 

[Bob Foster]

Would you bring up the issue with Genesis? It happened to me couple days ago, brought to deader checked and said no problem with the 12V battery. Hopefully they aware of this issue.

For what it worth and I have only had mine for two days but this morning after 12 hours of almost no charging I found that if you press and hold the button on the charger you can go from the default 6 to 12. I'm assuming we are talking amps here. I will try the 12-setting tonight but I still think the 110 is useless.

 

[MovingOn]

I agree especially if it snows where you live.

I was worried about this, but it was not a big deal at all in the winter. The angle is closer to a car than an SUV.

I agree I get lots of snow, its not a big deal at all. Also the rear spoiler really helps deflect rear wheel kicked up precipitation. The Ioniq 5 was horrible for this and absolutely needs a rear wiper. On the GV60 it would be "nice to have" feature but I feel I can totally manage without it.

Well we gets lots of snow here on the rock & it was really was no problem last winter. No different than the Stinger I had & other cars too. I can't believe some people said it was a "deal breaker" for them.
