I’d bet the battery is an issue. Possible internal short. Hyundai uses AGM batteries in the Kona and god knows who makes them. These are not like the typical flooded lead acid batteries were used for years.
running the car for 30 minutes probably did little good. Kona uses a “smart” charging system designed to maintain charge rather than charge a dead or low battery. A good half hour run down the interstate will help to charge it. Not idle speed.

After running the car for 30 minutes after the Triple A jump start when I was backing into the garage none of the cameras or parking warnings were working. I then noticed that the parking safety button on the console was lit. Tried turning it off and on and it stays lit. Checked the manual for the fuse location and pulled the fuse. The light on the button stayed on. Fuse panel is not lableled for an average person. Don't know if I pulled the right fuse or not. It only says module four ten amp. Now none of the safety features work at all. No cameras no sensors. I have an appointment for the dealer on the 18th. Problems with the bluetooth also. When I was trying to change some settings I got a message that the system was unstable and I couldn't make the changes. Did a system reset and no improvement. My iphone says the car is not connected in bluetooth but it is actually working on the car. I might as well be driving a 1950 Studebaker. So disappointed in the car and Hyundai. The parking safety button is staying lit after the car is shut down and all other lights have shut down. At this point I don't know if the car is safe to drive or not.

This sounds like it's above and beyond a dead battery issue. Hope Hyundai can get a handle on these problems. After bringing my car in last week (which I waited 3 weeks to get an appointment) I don't have a lot of faith in their ability to come up with a solution as they told me to get a battery tender.

Rick2055, keep the rest of us informed after you see the dealer. This Hyundai 2024 Kona parasitic drain problem is affecting more and mroe owners. I really like mine but need a car that I can depend on like my last 2020 Kona.

I continue to deal with this issue. Drove car on 6/11 then parked car over night had no report of issues (i have third party battery monitor (bouncie)) next day drove car 50 ft. at 6am, 8 hrs later monitor reported batter at below 11.5 volts. I now have a battery tester that i purchased at NAPA it read cold battery at 11.2 volts i have run car for 15 minutes battery now test at 12.4 volts i will check it in the morning to see how much it has dropped overnight.

We've got a 2024 Kona Limited FWD. We were away for 18 days. Got back, Kona started with no problem. If the dead battery problem was to happen, I guess that would have been the test. I hope it gets figured out. Gary

It's hit or miss. You can leave it alone for 3 weeks, and it will start up, or you can leave it alone for two days, and it won't start. That's why it is so hard to find the problem.

I actually found the battery draining the last time it happened. There was nothing running or turned on. I put my volt meter on the battery and could see it draining off. Not a steady drain but looked like a relay or switch turning off and on. Took a short film clip of what the meter was reading. When I take the car back to the dealer next week I would like to talk to the shop foreman or the tech assigned to my car but I doubt if I will be able to get past the service writer. There was enough juice left in the battery when I tried to start the car and I got a message on the main display stating" There is an outside parasitic source draining the battery". What would be considered an outside source on a self contained system. Wish I had an infrared heat gun and I would have looked for a heat source while the battery was draining. When you have a major drain on a battery like that it creates a lot of heat. Another downside of the last episode was that none of the cameras and safety sensors connected to it work. Car is okay to drive but I can't rely on any of the safety features to work. Surprisingly the blind side monitors still work. Will post the results of the next appointment afterward. One other quick note. After I lost all the cameras I went into setup to see what was enabled or not. Tried to tweak the settings and got a message that the system was unstable and it would not let me change any settings. Have to go on a trip next month and round trip will be about 2K miles. Don't know if I can trust the car or not.

Got into my car late Friday afternoon to go out and grab a bite to eat. Started the car and immediately got this message on the display"An outside source is draining the battery. Didn't know if the process would continue after driving the car and leave me stranded in a parking lot. Decided to leave it home and drive the reliable car. After I got home I checked the car and from what I could tell the battery draining process stopped after starting the car before. Put my battery charger on the car and it took about three hours to charge it back up to 100%. There was nothing running on the car when the battery was draining. Back to the dealer on the 18th for another useless appointment. Will post the results on the forum.

Dealers won't do anything until Corporate acknowledges there is a problem. My dealer told me it was normal because I don't drive my car a lot, BULL!!!. I have owned 20 cars in my lifetime and never had an issue with battery dying because I might not drive the car for three days. They told me to buy a battery tender, that was their solution. I am wondering if the new CCN3 system Hyundai is starting to roll out in all their cars is the issue, I also Wonder if other models beside the Kona are having issues.

 

[david13]

How did you learn corporate is aware of the issue

I am not saying they know, even though common sense would dictate between the dozens of people online that have reported this problem and the untold amount that don't report online, they do. Every trip to the dealer for service gets reported to corporate.

Well count me in on the dead battery group...I came out this morning to find my '24 N Line which i purchase 1.5 months ago battery was dead....I made sure to keep all the doors locked and also had the AC Drying Feature turned off....

 

[Floplop]

Well, that puts the lock door with key fob and keep keys in shielded box theory down the drain. I keep mine on a battery tender, and I think it's the only way to avoid a dead battery as of now. I think a new Subaru Forrester is in my future if Hyundai doesn't man up to the problem.

Do a little research on Subaru dead battery issues. My daughter is in on the class action suit for a battery issue on her 2021 that started 2 years ago. Subaru keeps the car and says they can’t find a thing. They put a new battery in and it was okay for 10 months. Now same old same old.
She’s starting to regret trading her 93,000 2015 Ford Fusion which gave her no trouble. Being an ASE certified tech myself and in the auto repair business for 58 years, you better believe I’d hear from her immediately if she has a problem.
I’m wondering if Hyundai didn’t just get a bad batch of batteries.
We’ve had no issues with our 2024 Kona Limited and we do have AC drying turned on on both of our profiles.

Thank you I will, I am looking at the 2025 Forrester (new redesign) so maybe I'll get lucky. People have reported getting a Battery replacement from Hyundai and still going dead, so I don't know if it's the battery, I tend to think not. My dealer tested mine for 2 hours, on a new machine Hyundai just sent them, and it was fine. He told me if the Battery was bad, he would have no problem giving me a new one, but it's not.

Update: I got into my Kona using the mechanical key and jumped started it...I then drove it over to my local Hyundai dealership where they determined the battery was shot and immediately replaced it with a new one....I was there for less than an hour total...I spoke to the Service Manager about this problem and even sent them links to a few threads here on the forum showing how widespread the problem seems to be! They are documenting this and sending a report over to the engineers at Hyundai for further investigation...

Had the problem reoccur the other day with the fan. Emailed Hyundai and they called me about 30 minutes later. They told me they were escalating my case and had a different advisor called me and wanted documentation. They advised me to make another appointment and I did yesterday. I have an appointment June 18th to take the car back to the dealer. Unfortunately the outcome will probably be the same where they can find nothing wrong with the car. I am wasting my time and the dealers time but will go through the motions for documentation purposes. I am not an expert but the car probably has a bad sensor somewhere or its in the programming in the car. Hyundai uses their own operating system so an error in the coding could cause problems. If you can check your car before you go to bed and make sure the cabin or motor fan is not running. I have found it running late at night at least three times. To reset it and turn it off you have to start the car and let the system load. Let the display get to the home screen and then shut the car down. This shuts the fan off at least until the next time. Good luck to everyone involved.

When you notice that the fan is running, have you checked if it indicated as running on the Bluelink app?

At only 3 months old, neither of our smart key fobs would open the car.

We tried to use Blue Link Digital Key 2, but it was unable to communicate with the car.

To try to get into the car, we followed the owner's manual instructions to remove the small door handle plate with the mechanical key. But putting the key into the slot under the handle successfully proved impossible for us.

So the dealership (Gettel Hyundai of Lakewood Ranch, Bradenton, FL) had Roadside Assistance (AAA Locksmith) come out to get into and try to start the car.

It took 2 of us to remove the small door handle plate, (one to hold the handle up and the other to try to release it with the mechanical key in the slot) but he finally did and then used the mechanical key to enter the car.

He opened the hood and put the jumper on the battery and declared it was totally dead. So he jump started it.

After a few seconds the car would start. But before he left, he disconnected the charger to see if it would start. It wouldn't, so he charged it again and started it again.

I immediately drove it to the dealership who kept it for 3 days performing battery diagnostics looking for "dark or parasitic current drain".

They couldn't find the cause, so they returned the car. Note: They didn't replace the battery we assume because they felt it wasn't the problem.

In the paperwork we got, the service tech noted, "parasitic draw test showed a multimeter reading of between 13 and 54 milliamps". Because this was a 2024 model, we assume Hyundai had no parasitic draw standards and they weren't sure if this was normal. So they tried it with another 2024 Kona off their lot which "found the reading exactly the same."

Later on this forum, I found only one person who'd reported a similar 2024 Kona battery drain problem and posted this response from his dealer:

My dealer told me that the radio needs to be fully off (black screen) and the doors have to be locked not once, but twice and with the key fob, not the button on the door. Otherwise they can both drain the battery, even when the car is off. I've had my battery die twice on me due to this issue.

I've asked the dealer if they were aware of this abnormal procedure to turn off a Hyundai, but have not heard back yet.

It seems it shouldn't be necessary to do all those steps to avoid " excessive parasitic battery drain" that makes our new car unusable.

Any other Kona owners have this problem and have hopefully solved it?

Just happened to my 2024 Kona for the first time. Battery is totally dead. NOT a good thing. Hyundai better fix this issue and soon or they are going to get sue!!!

I have had the same problem since i purchased a 2024 Kona in March. I believe the problem is worse than hyundai knows. I suspect that most people exerience this problem when bluelink doesn't work, so they report an issue with the app when in reality the app works fine. There are many fixes to this issue on the forum and all work until they don't. I have been collecting data on the issue and so far the issue appears to be so random that it is hard to pin point. The double lock with the key fob works most of the time but not always. My recommendation is to get a car monitor system it is not as hard to do as one thinks. I use one called Bouncie the is system is around $30 from amazon and cost $8 a month for service. This will alert you that battery is low so you can run the car for a few minutes to charge battery. It reports the battery low ( below 12 volts but greater than 11.5 vots) I run the car for 5 minutes than disconnect the monitor/reconnect the monitor (this resets the monitor). Recomendations so far inclued: 1. Use key fob and lock door twice with key fob. 2. No short trips (not enought time to charge battery) 3. Check rear hatch and tighten rubber gaskets 4. Turn every thing off (radio, lights etc). For peace of mind until you purchase a monitor system I recommend use the key fob but lock the door with key fob not twiced but 3/4 times.

This issue should be taken care off by Hyundai and not the buyer. I am a 60 year old woman and I need a reliable car.
