Just for everyone's info I found the cabin fan running in my car in the garage for the fourth time yesterday. Have found the motor cooling fan running twice. Contacted Hyundai again by email and they said someone would call me. The someone who called me back was a script reader. She told me she had no information that anyone else was having the dead battery problem. She also stated that if the problem could not be duplicated at the dealership Hyundai could not help me. In other words Hyundai is hanging us out to dry and not even acknowledging the dead battery problem. If either of the fans decides to run while the car is in the garage or driveway overnight you are going to wake up to a dead battery like I did. Wasted my time taking the car back to the dealership after the dead battery and they told me they could not duplicate the problem. Therefore it doesn't exist to them. I have had to resort to checking the car in the garage everynight before I go to bed to see if either fan is running. If it comes on after bedtime it will be dead battery time again. Going to research to try and find out if there is any organization that I can contact and escalate the problem because Hyundai is playing dumb. Good luck to everyone. Just an afterthought, the fans in my car are coming on usually after it has been driven and been shut off in the garage for at least two or three hours.

I am ready for a class action law suit if they don't fix this issue soon.

My Stealership, as well as many other Stealerships here in the US, like to install LoJack antitheft GPS devices in all their new cars and then add it as a markup item...

I recently purchased a '24 Kona N-Line that had one of these installed and I refused to purchase the Kona with this "Dealer installed" option....They disabled it and after inspection this morning I found that it was still hardwired in the system...It was not connected, nor piggy backed onto the OBDII line port but instead still had 12vdc power and control line tapped into existing lines...

Recently after one month of ownership and only 850 miles my battery died and had to have it replaced by dealer under warranty...Wondering if this LoJack which has been disabled but still hardwired into the system could be a problem?

I also have come on occasion to find the climate fans running even with the AC dry out feature disabled, door locked with fob, and fob stored in a faraday box...

I have an appointment with Service next week for another "we owe" item and will ask that they physically remove this LoJack device that's still hardwired in the system....

Stay Tuned....

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?

Was not aware of need to use fob. I used the door button all the time. 5 months in and battery completely flat. So many fault a in this car. Should have stuck with VW troc

At least you got 5 months, I got two months and Battery died.

After the last episode where I lost all camera function on the car it went back to the dealership exactly one week ago today. Do I know what is happening with the car? No I do not. One week and not a call or text from the dealership with an update. Sort of expected it because I went through the same thing last visit. Hyundai USA rep called me yesterday when I was out. Was in a no signal zone when she called. Didn't see her voice mail until much later. Called her back and left a voicemail. Did not get a call back. Becoming more stressful by the day. Have another car in the household so I have not been stranded. No offer of a loaner from the dealer. Not really happy with Hyundai. There doesn't seem to be any communication between the dealers and Hyundai. Now with the cyberhack going on with the car dealers I am not sure if I will ever get a car back.

Here's the actual Hyundai battery diagnosis procedure TSB.
If every dealer is not performing this diagnosis when presented with a battery issue. they are doing it wrong.
Kona owners should never be presented with a dead battery without Bluelink first sending a notification that there is a problem so the car can be started, instead of waiting for roadside assistance to boost the car.
Dealers should not be telling owners of a brand new car to get a battery tender or to drive the car more to avoid a dead battery.
Hyundai needs to fix the OBDII port in the Kona so it works the same as millions of other cars when an external device it attached to it.

I'm having the same issue, have a 2024, the vehicle has been to the dealership 3 times, the battery has been replaced. I don't think that they know what the issue is. Over the past couple of months I've done my own troubleshooting - turned off the AC running while off, it still died, I put the key fob in an RFID blocking pouch, the battery still died. I uninstalled the digital key and didn't have any issues, so this past weekend I decided to reinstall the digital key, I really like this feature, and sure enough the vehicle was dead Monday morning. I'm running Android Samsung Galaxy S24 Ultra. I'm almost positive that it's the digital key after all of my troubleshooting, I just don't know how to fix it. I carry a portable jumper to be on the safe side. I uninstalled the digital key again and am going to see how the vehicle performs this week.

I was reading a couple of months ago about people suggesting uninstalling the digital key, so I did, I don't use it anyway. Since then, I have not had a dead battery. I don't know if the two are related, but crossing my fingers, since the only thing my dealer told me is to carry a charger and battery tender with me.

I never had the digital key installed or enabled and my battery still died even with AC drying turned off, tapping the close button twice on my fob, and storing the key in a Faraday box...

Had dead battery issue about 2 weeks ago on a Monday morning. Didn’t drive car on Sunday. Drove it to dealer who said something was drawing a steady 2 amps. They went thru fuse panel 1 by 1. Turned out it was the head unit which basically drives all the electronics more or less. Replaced it last week and so far so good

You're now the 3rd person I've seen recently that had the head unit replaced due to dead battery...

I had my battery replaced a few weeks ago after only one month of ownership but they never said why it failed....Wonder if Hyundai now knows the root cause which is the head unit?

 

[Kitkat7931]

That's really unacceptable to have a two month old car fail you three times. Hope Hyundai is taking notice and trying to find a solution. I have an appointment next week for the two recalls. My car has failed me one time and I was lucky that it was at home in the garage. I am going to ask a lot of questions when I drop my car off. I will post what information that I get on this forum next week. Good luck with your car, it sounds like a nightmare. Hyundai probably doesn't know what is going on yet. I wouldn't expect an OTA update any time soon. I may not be a software problem but something electro mechanical.

I've called three Hyundai dealer service departments (Bradenton FL, Fletcher, NC and Asheville, NC. NO ONE admits they've had any 2024 Konas in with a battery drain problem. They all want me to bring my car in for a several day battery diagnostic again like my Florida dealer did...and said they could find no cause of my dead battery.

Had it happen to my 2024 Kona Limited once. I have gone into the garage and found the cooling fan on the motor running twice for no reason. Had a doctors appointment last Wednesday and coming back to my car in the parking lot after the appointment I found the cabin fan for the a/c running. Heard it as soon as I entered the car. Nothing else was on or running. If either of the fans had decided to start running during the night the battery would have been dead in the morning. Took the car back to the dealer on the 14th for the dead battery problem and two open recalls. Wasn't optomistic when I left the car off and guess what? They couldn't find anything. The service writer said that there was no information about the problem in their database. Left the car at the dealership until the 18th and they didn't find anything. Said the problem didn't happen while it was there. What are the chances of a random problem happening in a four day period? The whole service appointment was a comedy of errors. Guess the honeymoon is over with this car. Don't know if they are in denial about the problem but I am really pessimistic about a fix coming anytime soon. Maybe contacting the NHTSA would light a fire under someone. Having to spend money for a jump start device is ridiculous. Better than being stranded. Hope everyone in this situation is contacting Hyundai.

Greetings,
As far as Corporate goes, don't hold your breath. I had a 2021 Kona that, out of the blue, rev'd up and then stopped dead in its tracks in traffic. Long story short...spent over 6 months between the dealer and Corporate trying to get them to do something. Since it did not produce a 'code', they would not do anything. I had a video from my dashcam showing exactly what happened. I gave up and traded it in for a 2024 Kona Limited.

Now, I have this event last night with the cabin fan mysteriously coming on much later after being parked. My dashcam captured the event. Here we go again. I'll be talking to my dealership next week. Stay tuned...
Gary

Turn you a/c dryer off..

I am having this exact issue with my 2024 Hyundai Kona. Car unlocked and even remote started but I go to start it it say no key found. It's at the dealer now I am afraid of the car now. It's a Lemon!! I haven't even had it 3 months yet. I'm so mad!!

 

[Rick2055]

Have had no problems with my car since the June 18th visit. They found a wiring anomaly in the ADAS module. Translated Advanced Driver Assistance System. Car has behaved and done nothing strange since the visit "Knock on wood". Had a couple of minor things that were different on the display screen when I got it back. Managed to work around them so that most work the way I want it to. Good luck to everyone and hopefully my dealership was in direct contact with Hyundai.

My Bluelink has also shown the car in Costa Mesa. We’re in Florida. Wondering what could be in Costa Mesa.

That's the location for Hyundai Motors America...Occasionally the location for my Kona will show this location in Costa Mesa California! This also has been reported to have happened to many others!
