You can’t activate Utility Mode while plugged in and charging. The 12v battery does charge whenever you are charging the high voltage battery as well as in Utility mode. A good replacement AGM 12V battery will rarely see more than one brief charge per day. Ours goes several days without any charging when left off.
Interesting. I am surprised to hear that charging the traction battery (HV Battery) does not cause the 12V battery to also be charging as required to keep it topped up. Based on the behaviour you showed, it seems that when the vehicle is off there is no charging being done to the 12V battery even when the traction battery is being charged. It appears that the 12V is going dead on its own when the vehicle is parked in the garage even if the charger is active. There would seem to be four possible reasons for this to be occurring… 1. The 12V battery is in a poor state of health and the normal loads it must sustain (like the clock, wireless communications, remembering radio station presets, listening for the key FOB, etc.) when the vehicle is off is enough to drain the battery overnight. 2. The circuitry that is used to charge the 12V battery from the traction battery is faulty. And hence it runs down over a period of time. 3. Is that you have some unknown phantom load on the 12V system that is draining the battery when the vehicle is parked - such as interior lighting left on. 4. Battery is at end of life. Option 2 seems unlikely as you can operate the 12V charging circuity to operate when going into utility mode. My guess is that your problem is caused by the 12V battery as it is either defective or has reached its normal end of life. From the video, it looks like a normal lead acid automotive storage battery is used - these batteries don’t take well to deep discharge cycles. One other comment, I am surprised that the vehicle is allowed to be dead when the 12V system has a dead battery. You need to provide another power supply just to access the menus (Catch 22?) to access utility mode to get the 12V battery charging. It would be nice if there was a temporary override switch to provide power to the 12V system from the traction battery when the 12V system is dead.
Yup pretty spot on. I will note that the battery is only about 4 months old same as the car so its, either deffective or its the update thing. or one of the things you mentioned. It is weird, my bolt batter lasted 6 years with no issues, I replaced it based on age not because it was giving me trouble. thanks for commenting
Good video! As the owner of a '22 Ford Mach-e, I can understand the 12v issue. Many Mach-e owners have reported the 12v dying on them. I'm at 25,000 miles (40,000km) and have no issues. From what I understand the high-voltage battery must run for a while to charge the 12v. If you don't run the car often or long enough, the 12v may die.
That could well be, but that is a BMS issue I would think. My 2017 Bolt never ran into this problem. Frustrating eh! Thanks for the comment! and glad you liked the video.
My 12 volt battery died after 18 months, and 12,000 miles (19,000 ish km), so I feel your pain. The software updates to fix this were obviously not effective, and probably no more than service theater, as the brand is taking a PR hit from this issue. I’m taking mine in next week, and I’m expecting very little satisfaction down here in Las Vegas. I hear the dealerships won’t even supply a new battery unless certain parameters have been met. That is unacceptable to me. But… I have to at least give them a shot at doing something. Thanks for uploading your video, and GO LEAFS GO!
What is your opinion of any dealerships in Las Vegas as far as helping owners and future would be owners of the IONIQ 5 (2022 models) with repairs involving potential ICCU replacement, or the software fixes enhancing the Level 2 overheating issues ????
@ I have had poor results with my LV Hyundai dealership. The 12 volt battery issues only was solved by me replacing it at my own expense as Hyundai said they needed my car for 4 days, and wouldn’t give me a loaner. Since I replaced it, all has been well at least. I love the car, but not the service. As far as the level 2 issues, I never had a problem. I don’t use it at home. No need. When I use it at a hotel, it seems to charge slower than advertised. No big deal IMO. The QuickClip DC charging has been a highlight.
@@Bum_Hip OK thanks for noticing my question: I'm glad you mentioned you charge outdoors only in hotel environments, I'm curious: Do you find the outdoor weather in wintertime is making a difference in much slower charging times? I don't have a garage, but for Las Vegas January and February winter charging, how much slower can it really be? The 2022 IONIQ 5, did not come standard with a heat pump like it did in the 2023 models, and since there cheaper, I figured why spend the extra money , as far as what I've read, that's the only difference between the two model years: Note: On a resiential level 2 charger with the correct materials in the wiring and panel, etc...the IONIQ 5, is technically suppsed to charge from 10% to 80% in apx 7 hours. (in the longer range SE trim)
Mine was failing 12v battery as well and in the same exact conditions. It always happened when i was charging in garage. The dealer was unable to find the problem. But now the ICCU failed and guess what. The ICCU is responsible for charging 12v battery and for charging HV battery from AC. It is liquid cooled and it's leaking. When you are charging the coolant circulates and leaks probably.
I have a 23 Hi5 and have not had the dead battery problem. However, I have had a problem some call Zombie Mode. When I try to shift out of park I can not get it to go into D or R. The car is thus immobile. I had it happen in a carwash after I paid for my wash at the entry gate. I had to open the door because I couldn't reach the card slot so the car shifted into Park. I couldn't get it out of Park. After turning it on and off a couple of times and trying several times to get it to shift it worked. Took about 5 minutes. I put my foot on the brake each time I restarted it. It has happened four more times randomly. Each time I am able to get it to shift after doing various things. The dealer won't help me if I can't make it happen in their presence. Hyundai said they can't help me without a dealer experiencing it. They recommend taking it in to the dealer and leaving it there so they can try to duplicate the issue. No loaner offered. It is usually a couple of months between each experience so I can't imagine it is going to happen when the mechanic at the dealer is checking it once or so times a day. So, it looks like I am on my own. I think it is a low battery problem but am only guessing. I have purchased battery tester and a jump start battery. Hopefully, if it happens again I can just jump start and the problem will be over for the time being. I have had the recall ICCU update done. I don't know yet if it fixes the problem. Do any of you have any suggestions for what I can do?
That is the poor quality battery I had, which died 4 times, twice brought it to Kia service, they checked it and said it was fine. Died again and replaced the battery with a real AGM for less than the prorated warranty I would have had to pay, that was 2 years ago. The AGM still rocks!
Yes had the same experience with my EV6 which is identical under the bonnet(yes UK), however the battery never eally recovered and I had lost confidence in it, so I replaced it. I noticed you had a chamberlain garage door operator. I had 2 of these one on each garage, they both failed after about 20 years, they stripped a nylon gear inside, I bought a pack of 2 on ebay, easy to fit but they only lasted a few months. I think they were just a 3D printed copy, so now you know.
Why do it hard? Get a standard 12v battery charger, disconnect your car from the battery and charge the battery fully with the charger. Thats how its been done for decades and still works.
It's a thought but its really not hard to put the car into utility mode, my bigger issue is that the car should not kill the 12v battery within 4 months of ownership, when my Bolt gave me no trouble in 6 years
No way. Not going to happen. I deal with diagnosing computer systems all day long. I'm not going to spend my free time trying to make my car work like its supposed to. You shouldn't need to black box debug a toaster.
Guys the real solution is just to swap for a new battery and that's it. It's not iccu it's not blue link. Swap for new battery and try to get reimbursed from Hyundai cuz it's a ev design flaw. They could design it where the ev cars don't need 12v swapped every 2-3 years but there goes millions down the drain for the battery companies if they did that.
Electricity and where I live that is 1/3 nuclear, 1/3 renewables and 1/3 fossil fuels, but they are supposed to be zero emission by 2035 at the latest but likely sooner. It's not an either / Or thing it's a this AND that thing. The cars need to be produced using green power they need to drive on green electricity, and they need to be fully recycled. It's a whole of society thing.
I don’t care for zucchini, so I don’t watch cooking videos about them, why would one take the t8me to watch, then comment about a car they do not care for, and would never buy? BTW, if you know of an ICE vehicle that will never have any problems, I am all ears.
Connect: Positive first, then negative.
Disconnect: Negative first, then positive.
Thanks
I tried that, but it wouldn’t jump. So I did negative first then positive, then it did in fact fire up. 🤔

I just stopped using bluelink when battery got down to 30% and it seemed to help
Iccu recalled issued. Now iccu is covered by Hyundai long as you own the vehicle even if the warranty expires

Just bought an interstate agm battery hope it works out cuz I saw that agm might be an issue cuz it requires high voltage or something like that.

$5000 to repair unless you still have warranty.
its 4 months old
I don’t think even the best 12V AGM battery will cost $5000.
