Thanks for your post! I am in the middle of this exact same problems: tomorrow will be the 3rd jump in 7 days and the dealer checked & charged it two days ago. No one has mentioned the double lock with fob and radio completely off situation. My 2024 Kona came off the lot Jan 1, 2024. Using the mechanical key is a royal pain!

 

I may have found the solution open rear hatch and look around rubber plugs on hatch door, hand tighten those plugs there is a fat one and a thin one there should be no gap between them. Also when open close rear hatch make sure you run the car within 2 hrs or keep engine on while doing this. A guy in England discovered this. He believes that there is a sensor that is triggered and running the engine after closing hatch seals door. Also the gap between the plugs triggers the car in thinking hatch is open so it is trying to seal hatch.

 

My daughter had the same issue. One month old Kona . Took back to dealer they found a gps tracker that was as causing the drain. The car was a dealership transfer neither she or the dealer she bought from know it was in the car.Tech saw some wires under the steering wheel that was out of place.

 

That is a great observation. My vehicle was also a dealer transfer, as the Kona I originally chose was just off the transport, with no dealer adds. It had some sort of mechanical issues, and the dealer found a similar Soultronic Orange about 100 miles away and sold me that one. The replacement may very well have a dealer add tracking device installed. I will check early next week.

Thank you.

 

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.

 

Any updates? I am about to get rid of it because I need a reliable vehicle and cannot afford to be stranded. It's a shame because I really like the car.

 

I am having this problem. I bought a jump pack, so I can jump it myself. Dealer told me next time it dies to have it towed into him in the dead state so they can see what's going on. I already know they can't fix it, so I will give them the opportunity, and then I will trade it in on something else. If it was a bad battery, I would just get a new one and pay for it, but it's not the battery.

 

After doing research and testing I think I found the problem for the parasite battery drain and bluelink not working issues. It appears that the problem is with the key fob. The key fob, per hyundai, needs to be within 32 ft to start car, but it acutally transmits up to 500 ft (some guy in England discovered this). What is going on is that it is establishing a weak link with the car, thus draining the battery. What is needed is to buy or make a Faraday cage. Here is how: 1. purchase an rf blocking box or pouch ($5.00 or more). 2. place key fobs in a tin can (i am doing this) can must have cover/sealed. 3. place key fobs in the refrigerator (which is a large tin can). 4. wrap key fobs in aluminum foil. So far this is working. It solves the bluelink issue because once the battery gets to 12 volts or less bluelink will not work. Remember not only must you have a faraday cage device for home but work, staying in motel, etc. Anyplace where the car sits for 5 hrs or more (not running) and within 500ft of the key fob. Also remember car comes with two key fobs. An interesting note: what the key fob issue means is that the quality of hyundai vehicles is so (so) good that that they created an issue by being so good. Possible solutions for hyundai tech is: smaller battery in key fob and/or provide owners with a portable faraday cage.

 

Thanks for the reply, but I don't think the key fob is the problem. There are probably 100k key fobs like this one being used all over the world. Hyundai would be swimming with problems if that was the issue with the Kona battery dying. On top of that, my keys have been in the same place in my house since I purchased the car and never had a problem up until 2 weeks ago. If anything, it's either the latest update, the blue link app or the using phone as key.

If I don't get satisfaction soon, I am trading it in, as it is not reliable. Let it be someone else's problem.

 

It is possible I am wrong and you are right. All I can say is it cost no $$ to try my solution and if it doesn't work one is out nothing

 

Trying everything I can, I don't want to trade it in if I don't have to, I like the car. I do know that Hyundai cannot and will not fix it unless the car dies while in their possession, and that could take weeks.

 

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 have heard the fan come on just one time since I owned the car, it turned off after about 5 minutes. I live very close to Canada, so it really has not gotten very hot here yet. My thought is that it's not the fan, as it would be happening to tens of thousands of people. The fan running is something common to all Kona's. I have an appointment June 4th to take it into the dealer, chances are I will have it traded in before that appointment comes. I have zero confidence in Hyundai being able to locate the problem, never mind fixing it.

 

I have a 2024 Kona N Line and I had a dead battery after owning the car for 5 months. The car had been sitting in the garage for 3 days. About 2 weeks ago, I had the warning "An external device is discharging your battery". This time it was not dead: what a relief. I am curious about the comment your dealer made about locking the doors with the key fob. Was this confirmed? If yes, that could be my problem because I never lock my car when I have it parked in my garage.

 

Make sure you shut everything off before leaving your car including radio, a/c, heat, vent etc. Close the door and use the key fob to lock it. Hit button at least 3 times to make sure everything power down. It may not work, but it cannot hurt. **** of a way to own a car.

 

Thank goodness I'm not the only one! I bought a brand new 2024 Kona Limited FWD with only 15 miles on it on May 3rd, 3 days later on May 6th it was dead. Took it in they said the battery was testing just fine, so it might have been low from coming off the truck. Next day, May 7th, I wake up and it's dead again. They had it in the shop for 3 days and couldn't figure anything out, so they put a new battery on and gave it back May 9th. Again on May 12th it was dead again. I took it in again and by May 15th it had been through several technicians and they still couldn't figure out what was wrong with it. So, that day I traded it in for another brand new 2024 Kona Limited AWD. Once again today, May 20th it was dead.... I'm about over this car and it sucks because I really love it.

 

Your scenario is the exact reason I am getting rid of mine. They cannot duplicate the problem and even if they did, they probably cannot fix it. I had it down to them twice already, and it was a giant waste of time. Plus, I live in a rural area and the closet dealer is 40 miles away, and I cannot be without reliable transportation. Too bad because I really like the car. People told me not to buy the first year of a new car, now I know why.

 

I've had my new Kona N-Line for a few weeks now and so far, so good...It also was sitting on the dealer lot for a good few months before I purchased it and service history records don't show any battery replacements occurring during this time...That said, I do double-click my key fob lock when I leave the car...I also keep both my C8 Corvette and Kona keys in a shielded faraday box to ensure no communications are happening between the fobs and cars...

 

2024 Kona limited dead battery after two months. Took dealer 6 days to tell me bad battery because warranty approval. I had to go to dealer and raise ****. All the service people scattered. The warranty approval happen in 30 min. I asked the double lock FOB trick nobody knew about it. I will contact customer at headquarters and not stop until I get an answer. Yes my handle cover got scratched because it is not easy to get off. Was priced $94 to fix it. I will pay and file a claim at headquarters

Unfortunately the Battery is not the issue, If it was, I would immediately get a new one and gladly pay for it out of my pocket. Local Hyundai dealers cannot even begin to fix this issue. The car has to be torn down at the factory and investigated to see what exactly is draining the battery.

 

Fellow 2024 Kona owners: Here's what I've sent to our FL and NC dealers trying to get Hyundai's attention. I suggest you do the same with your dealers.

Will, luckily, we still haven't had a repeat of the dead battery problem on our 2024 Kona Ltd. we had in February just 3 months after we'd bought the car from Gettel Hyundai in Bradenton Florida, but if anyone at Kona's U.S., EU or Seoul Headquarters is monitoring the Hyundai Forum, they would see it's a real and growing problem for 2024 Konas and Hyundai should be looking for the cause at the factory level.

Seemingly, none of the Hyundai dealer service departments can find the cause. After the cars are jump started by AAA and taken to the dealerships, the service departments test the batteries (which all test fine) and then keep the owners' cars for 2 or 3 days testing the entire electrical system but none of Hyundai's service departments can identify the cause and send the owners home...for many of their batteries to just drain again.

Several of them have warned 2024 Kona owners to not try to lock the car by touching the door knob, but click "lock" on the fob TWICE every time you leave the car.

Having a discharged battery in a brand new Hyundai Kona is a real inconvenience (especially with the difficult-to- remove lock cover on the driver's door knob). Some of the owners are talking about starting a Class Action Lawsuit.

My question: Is there any U.S. Hyundai dealer who will contact headquarters and get Hyundai actively working on a solution for all us 2024 Kona owners?

Here are are just a few of newest occurrences from the Kona Forum: (and I attached 4 or 5 posts with the same problem).

 

I don't know if you monitor Reddit, but there is a thread over there as well.....2024 Kona N Line Battery Dies Twice at 1500 Miles : r/Hyundai (reddit.com)

 

I called corporate and was assigned a case number. Long story short the local dealer was contacted. Dealer has been contacting me constantly if there is anything I need. So far free 5 year warranty battery. All scratches repaired on door lock cover. Corporate informed me they would research the dead battery issues and let me know. I have a direct case member direct line. They will close this case but if I have any issues I am to call them first to reopen battery case or new case. Local dealer took 6 days to diagnose a dead battery and replace. Corporate was not happy. Case member said my case got the attention of Senior staff

 

Can you let me know what you did to reach the corporate level?

 

Google customer service got 800 number went through until I got a person. Gave my story. Corporate called me within 4 hours

 

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...

I have a 2024 Kona Limited AWD and love it. The AC blower is SUPPOSED to do that. Read the manual!!!
It explains it and why. It’s. actually a good idea.
You can always go into Settings and turn it off. Personally, I like the feature and it WILL NOT drain the battery.
Do people ever bother to read the manual? I found out so much stuff I never realized the car would do.

 

I am having the same problem with my 2024 Limited. Have found the cabin fan running at least six times. The cooling fan on the motor twice. One time I didn't catch it and had a dead battery in the morning. I have gotten into a habit of checking the car every night before bedtime to make sure one of the fans isn't running. Went shopping yesterday at Home Depot and was away from the car for about forty five minutes. Got back to the car and the cabin fan was running. Emailed Hyundai the same day and someone called me within thirty minutes. The call was a total waste of time because they want me to take the car back to the dealer. The fan coming on is a random thing and not predictable. The car could sit at the dealership for two months without the fan coming on. This time on the call there was a hint of them maybe buying the car back. The fact is that I really like the car and no one else makes a small car with all the options that a Limited has. Hyundai please wake up and at least acknowledge the problem and fix it. Going to the dealership is a waste of time because they will tell you that the problem can't be duplicated. If they can't duplicate it then it doesn't exist. Next time it happens I am going to waste my time and the dealerships time on a senseless attempt to get something done.

 

I feel exactly the way you do. My Hyundai dealer is small and has 2 techs, of which 1 of them in on vacation. Needless to say, they cannot fix this issue even if there were 10 techs there. It has to be investigated at the factory. I also love the car and I have been shopping around to trade it in and nothing even comes remotely close to having all these features plus a peppy engine. Thinking of moving into a Mazda or Subaru. I will give up a lot, but having something that I KNOW will start when I need it is more important. I have an appointment June 4th (waited 6 weeks for it) I know is a giant waste of time but will probably go.

 

Greetings,
I just remembered that we had a similar problem with our 2021 Kona. One day, the car was just dead. Had to have it jump started. It only happened once so we never figured out what caused it. Now...our 2024 Kona Limited seems to be waiting for this to happen with it. As I have said in another posting, HyundaiUSA is useless. You can't get past the so called Hyundai Care Center case managers. All they say is take it to the dealership. And the dealership will do nothing unless Hyundai USA tells them exactly what to do.

Greetings,
I just found this on another Hyundai Forum. This might answer some of our questions why the fan turns on after the car has been turned off. I searched the owners manual with 'auto-dry' and verified that it is in the manual. Who knew????
So for me, I am now less worried about my fan coming on after the car was parked. The fan did turn on about 30 minutes after it had been parked in the garage. Hope this solves some issues. But probably not the dead battery problems.

Great to see someone else actually reads the manual. I learned so much from reading.
my 2024 Kona Limited AWD so far is a great little car!! Love it.

 

Not worried about it either since I found the setting to turn it off. It's really not needed, and if it comes on and gets stuck for some reason, it will drain the battery.

 

Greetings,
Seems you shouldn't be worried only if this is what is causing the draining of the batteries (getting stuck). But we don't know. Kinda strange no one brought up this function before for the fans coming on.
Gary

 

I came out to the garage once and found that the fan was still going with the engine turned off...So I decided to turn off the "AC Auto Drying Feature" a while ago which keeps the fan going after the engine is turned off and the fan (with engine turned off) hasn't turned on since then...Since I live in So Arizona where the air is so dry here to begin with, there's almost no moisture in the air to condense anyways! I think this feature may very well have contributed to the drained batteries reported by others!

 

I have it set to “On” 2024 Kona Limited. We live in a high humidity area so that fan runs periodically.
never had a dead battery. If it makes you feel more comfortable, leave it off. Kudos to Hyundai for making selectable features.

 

We are in Canada and are having the same issues. The car has died twice and service could not duplicate the issue in the shop for 2 days. Told us to take it home and if it happens again to have it towed so they can verify the dead battery. We were told to only use the fob to lock/unlock the car and to press the lock 3 times to make sure everything is turned off.

 

I wonder if they just got a bad batch of batteries. I made them put their top 5 year battery under warranty. My original battery had no markings no date made no expired date. My new one has everything and is a 5 year right on. They have equipment to read the draw on the battery when it is off. We put our fobs in faraday bags at night so the car can not see them and go in standby mode. I also turned off the auto fan under climate control. If that turns on it will run for 10 minutes supposedly. The auto is supposed to dry out the vents after long ac usage. Some engineers came up with this

 

Have you read about insurance dongles draining the battery

 

That’ll do it!!! Pin 4/5 on the OBD II connector are Chassis and Signal ground respectively. Pin 16 is B+ and hot all the time.
plugging a dongle on requires power so there you have it. Dead batteries. Ditch the dongles. OBD II WAS NOT DESIGNED to have this crap plugged into it.

 

Have you read about the battery being drained by insurance dongles?
