I have a 2022 Ioniq 5 Ultimate with no heat pump so cannot pre heat the traction battery. When the car was just over 2 years old the 12v battery failed. The main cause, after several trips to the dealer and 4 call outs for the AA was a faulty battery sensor reporting 12v battery at 20v so the car did not charge the 12v battery and it dropped to 3v several times which killed the 12v battery. The dealer changed the sensor and 12v battery under warranty. Today I 10:10 have another fault being the car will not charge on AC but is OK charging on DC. I am booked on the Channel Tunnel for a trip to Framce tomorrow so no time to get this fixed. Wish me luck.
I'm in the US and have been driving an Ioniq 5 for about 10 months with no issues, but have had 2 ICCU updates, including 1 about a week ago. I also drove a Model 3 for 4 years and other than the lack of a rear wiper, I'm very satisfied with the car.
Ioniq 6 here. No rear wiper either, but when driving it on dusty gravel roads I have seen exactly WHY. The car's aero design is SO good that no dust gets deposited on the rear. In the rear-view I can see twin dust spirals racing off behind the car, instead of the usual ICE car's vision-obstructing all-embracing dust-cloud. Not sure how the Ioniq 5 goes with this.
I live in Canada and in 2022 my 2023 Ioniq 5 AWD Limited arrived, I picked it up and drove it home really nice car. We bought it as our road tripper as our other electric is a very reliable 2020 Kia Soul EV which we had used for road tripping but the Ioniq 5 is much better as a road tripper with it's high speed DC charging. So I had the car for 2 weeks and decided to see how well it fast DC charges, well it did not, I tried multiple chargers and no DC charging. I live on a remote coastal community north of Vancouver and it is a 40 minute ferry ride to get to the dealer service department. Needless to say after 7 trips on the ferry to the service department all 6 times they failed to fix it, on the 7th time it was finally fixed at another Hyundai Dealer, was quite simple a pin had be bent on the Temperature sensor module (causing a short) for the charging port which fried the module, even the other dealer replaced it twice, not understanding the cause. We sold it and bought a 2023 Tesla Model Y Long Range AWD and never looked back.
If you get an Ioniq 5 or 6, change the 12v lead battery for an AGM style. Plus make sure you're local service centre gives it a once over. Lots of updates since the release for ICCU.
Hyundai have had a service recall out for updating of the ICCU which impacts charging and other issues. It came out locally here earlier this year and mine was done at the dealers in about May. I have just seen on a FB page that it has only just a week ago been announced in the US. Lady really needs to check with her dealer and check the recalls in UK. I reckon she may have missed the recall notice. Been waiting 1hr 20min for AA and going to be another hour 😳 Sheesh, what a crappy roadside service! I have never had to wait for more than 45 min for service by our RACV here in Australia.
I had the same fault on our Ioniq 5. It wouldn’t charge on the home EO chargers. Tried public chargers the same. Called the service centre and first appointment was for three weeks ahead. They fitted a new ICCU and all was fine. It is a known problem, but not a recall item. We now have a Tesla.
Yes.. the lady owner did say the home charger had the same issue around a year ago. She said they had a Pod Point unit at home. If and when I meet her again the ICCU will need to be mentioned.
Time is precious to some not all. Most of the time Charging is done as you Shop, socialising, even working. If not the vast majority have home Chargers where you fuel up as you sleep at very cheap rates. This is relatively rare and let’s face facts… Thousands of ICE Cars breakdown ( some run out of fuel) everyday.
I’ve also got an ioniq5 but never had this. However there is a well known problem with this architecture with ICCU failure. Initially Hyundai tried a software update to prevent any problems with the ICCU which doesn’t seem to have worked. However not wanting to put a dampener on this. Some who’ve had the ICCU replaced because of failure have also had that one fail. One symptom is charging problems. Can I suggest, if not already aware, to join the ioniq 5 uk owners face book page where this is discussed in depth.
Mu ioniq developed a fault in Nov 2023, after a battle with the dealership to actually try and look at it they discovered that it needed a new ICCU. I had already suggested this as I looked it up on a forum. The car wasn't charging via AC, but would only charge DC. This got to be expensive and I received no interest or recompense from Hyundai. After the ICCU was replaced the car would charge AC but now will not charge DC as the dealership have told me that the car thinks that the charger unit is trying to charge the car at 120 degrees C so the car refuses the charge. Its now December 2024, its been in and out of the garage for the last year in attempts to sort it out. Now the dealership tell me it needs a new charger port and wiring loom. I've been waiting over a month for the part. Neither the dealership or Hyundai have been swift in sorting this issue out. I'm not buying Hyundai again
Your input is appreciated and I have noted from others that it seems the Dealers are never in a rush to put it correct. It has put me off looking at the Genesis GV60.
I'd seriously urge anyone buying a Hyundai to think twice. My dealership seems to employ decent types but I often get the feeling that their hands are tied regarding what they can do and what they can tell you
I had an ionic 5 which wouldn't charge at rapid chargers (anything over 7 kw), it would charge fine at home but not at any public chargers unless they were 7kw), took it to Hyundai who replaced the wiring in the charge port, after that it worked ok. Now I've got a Tesla.
ICCU issue and ac charging. In the background I see the 50kw DC charger. It will still charge ok on DC chargers, move the car - 3% will get her there and charge up there.
You should have plugged it in to show us the lights flashing. These cars flash if its set on timed charge. If there driving around a low charge from memory they don't charge the 12v battery and if all heating and fans on will drain the 12v. Saying that there is a recall on the charging circuits for all GMP platform cars . If the battery's cold it won't charge fast on dc if not prewarmed. Has it had the update when the sat nav is set to a rapid charger it prewarms the battery?. Plus was there enough charge left in the battery to prewarm.
The 12v battery was fine. It was an issue with the HV Pack. The lady had had a similar issue before. Thanks for the input. Any info is good for owners!
@@KKandEV Two ways the fault shows, 1 the car fails to switch on and therefore the 12v battery is at a low state of health or 2 the 12v battery as a low state of charge and not enough charge to power the charging electronics.
The charging/battery problems are well known and documented among the IONIQ 5 and EV6 communities. All the dealers know. It’s ridiculous. I have had 4 new 12v batteries and a replacement ICCU on my EV6 and I’m told there is another recall for the ICCU!!! Recommendation - Buy something else. 😓
My daughter's 38Kw Ioniq (still under warranty) threw a massive fit and did the same and she had to call the AA. The AA guy said he thinks the battery is bust. On the truck it went to the main dealer...It turns out it was just the latch on the charge port. The only dangerous thing about it is someone having a heart attack since the dashboard lit up like a xmas tree and gave doomsday messages!
I'm wondering why you didn't go through the motions on camera-show us what actually happens when it's plugged in. That said, it really isn't a good idea to run down that low any more than it is good to run an ICE vehicle down to a few drops of gasoline. That's hard on the fuel pump. I learned the hard way a few times about 50 years ago to fuel up at a quarter tank (25% in EV lingo). I walked a few miles in my youth with a gas can.
We have seen this problem with a GV60 and never let it get below 20% if we are doing short runs around town. We have had the 12v battery die on us twice in winter due to running heated seats etc with a low state of charge. If you are doing a long journey, this is not a concern as long as you plan to charge the vehicle on route or at the destination. On a long run the 12v battery will be kept topped up anyway.for us has been to "jump" start the 12v battery from another source, in some cases our yeti, and plug the car into an ev charger. After 30 minutes the 12v battery will be back up to par and able to take the load of the 12v circuit. We have proved that once the 12v battery has enough to start the charging cycle and the ev charger a meter will show around 75 amps being sent to the battery, an AA guy wanted to check all was charging once the car got running. The key is when the car switches on and starts charging, if the 12v drops too low the car goes into a safe mode and basically will not charge. Some forums have recommended swaping out the 12v lead acid for a 12v lfp, the advantage being that the lfp has c. 1kwh of charge while a 12v lead acid has c. 500wh (aka 50% of capacity). This allows more room during the winter months. For interest, if you watch the energy monitor while driving you will see the internal electrics pulling over 3k of power, this is a heavy load for a 12v battery system. To put that into context, 3000/12=250 amps. My only hope is that if an LFP battery is put in place that the charge controller in the car is able to charge at a high enough rate and therefore keep the 12v battery at a high state of charge. This is not a new problem, the more toys in the car, the higher the load on the electric circuit. This is the same problem that was seen with Jagular and Range Rover cars and caused them to have 2 x 12v lead acid batteries, one to start the car and one to run the extra electrics. We saw the same "fault" with a Zoe and an Outlander PHEV, but it was harder to achieve as there were less toys in the car. Our car is due a recall which will be implemented soon, I have asked what they are doing and specifically if the lead acid battery will be swapped for a lfp. I see this as a fault in execution and also piling too many toys in the car and therefore causing other issues. In summary, do not let the SOC of the car go below 20% if you are doing short journeys. If you are lucky enough to have home charging, put your car on charge over night. Also if you have home charging consider an EV tariff to make things cheaper. If you do not have home charging, in winter plan to chrage the vehicle at the supermarket or other ac charging location to keep the SOC above 20%. Above 20% is when the 12v battery will be charged.
Many thanks for the very intuitive comment. With my previous 4 EV’s over 5 years I’ve not ever come across it. Hopefully a few folk can learn a thing or two about this issue from this post. I’ve no idea if the lady has now got it sorted but I’m hoping she comments soon.
It most likely not charging because the 12v battery dead this happens to me 1 time I was on the freeway and my car had 7% enought range and got the same problem as her because the 12v went low screens and everything where working but car wouldn't drive a few feet and would stop lucky thier was enough area to pull over...I had a buddy flat tow me 4 miles with his truck to the eletrify america chargers and still wouldn't charge so I had to go home in a uber get a norco jump pack I had at home then another ride to the car I put the jump pack said battery was like at 9v I started it then quickly connected the fast charge and car started charging and everything was fixed ...they should put a volt meter in screen and people should carry a jump pack in case under 20% rage nomore alternator to chage the 12v axillary battery
IONIQ 5 uses Lithium Polymer Batteries NO ONE else but the Koreans uses that chemistry. There was a car-share service in Paris a decade ago that used that chemistry and the cars died a lot.
Mines never missed a beat but I don't do much much fast charging either mine did have recall on couple of things. One was something to do with the charging.
Ionic 5 owner for 3 years have not experienced any issues really. Not even the well documented 12v battery problems, still on the original 12v battery. Had the usual recalls and ICCU updates. Dealer has ordered a new 12v battery as a precaution.
Our Genesis GV60 threw up an error fault. Electric system fault with orange triangle while driving home. Then a red battery warning telling me to pull over and park safely. I was about 2 miles from home. I decided to risk getting home and with a mile to go the car went into turtle mode but still got us home. Car now with Genesis in Hampshire. The 12v battery I was told by the AA is ok. I suspect the iccu is giving false reading to the car. We are disappointed that they have not even looked at the car which they have had since Tuesday. I was told today they have a backlog of work. We have a Ford Mustang Mach E to drive while the repair is being carried out.
That’s not good… I’ve been considering the GENESIS GV60 or the EV6 Kia ( both sister cars) but have my reservations now. Some are saying there was a recall that fixed the issue?
@ I knew about some of the issues before getting the car. I also was aware of their sparce service network. Purchased the car second hand with only 2000 miles on the clock with 40% off list with 3.5 years of service left on it. The car to drive is fantastic compared to anything we’ve had before. It’s never nice to have a breakdown hopefully the Hyundai group will get this sorted soon.
I won’t be buying new on a Genesis…Been looking at the Premium as I want the Range and far larger Frunk. I would consider the AWD if price was good. Will Hyundai not service it ?
I didn’t film me asking if there was something I could do… which I did… she had already called the AA and been to two other chargers to try and get power. I asked her more than once if she needed anything.. as if I wouldn’t!! I also asked if she was willing to get it on UA-cam and she said yes if it raised the issue for others, which it has. I will leave your comment on here as I find it hilarious.
