Just a follow up to my post from Oct 29. I am not really clear on what they did in regards to my coolant refill error but the error hasn't appeared in over 8 days (knock on wood). They had reported the coolant level was normal and there were no visible leaks. They will schedule me in for the coolant pumps replacement when it comes in.

Just adding myself to the list, the warning having returned after about 4 months. In the first fix (under warranty in June 2022), the invoice stated:
Check Coolant light appearing on dash and report.
Carried out coolant flush as per TSB SF22016. Drained coolant, flushed with clean water and air, through hose. Carried out coolant bleed. Road tested, all okay.
Which it was. Until now.
About to book 24 mnth service, so will be including this issue. I'll report back if I learn anything of use.

Morning all, just to add my car to the list. 3 weeks after the 40,000 mile service I started to get the orange 'Refill Coolant' light on my dash, normally just after switching on for the first time that day, but it has occurred once of twice at other times.
The first time the car was booked in for a service the garage called to say that the problem was bigger then first thought and would need to book it in another day for a longer slot, but the car is safe to drive and charge.
The second time I got a call to say they had a problem with there compressor and could I bring it in another time, they did not say right away, but had the car most of the day before calling.
The third time the coolant flush was successful, but the 12v battery had lost charge and they can't get it off the ramps and will need to charge the battery overnight and would call me in the morning, so I was without my car until around 12 noon that next day.

I have read most of the replies here and can see it's a problem for a lot of us, but does anyone really know the reason for it to happen? Is it the service centre or a problem at Hyundai?

I love my car, it's been such a nice experience so far, yes a bit of charge anxiety when on a long (over 160 miles) journey and can't find a working charge point, but at all other time, just a pleasure to drive. I hope this is not the start of a down hill breakup, only time will tell.

As far as we can tell, Hyundai is indeed aware of the issue, but does not have a real fix for it, it's all patchwork and hoping for the best.

As the car sold low volumes and is now discounted, hopes of them spending time to actually fix it is low. The only positive light is that it happens to brand new SantaFes too, so they might find a fix for those that can be ported over to our Ioniqs.

I agree. Since they stopped making the car, replacing it with the Ioniq 5, I don't expect a fix. But the good news, is that hopefully that will give me even stronger grounds to claim a buyback from them. I read that you are pursuing the same option, do you have any details on what Hyundai will offer on a buy back? Have they offered cash or to exchange for an I5?

Add me to the list 2020 38kwh version premium se with 37k. Five year warranty is saving me and so far :-

On my second 12volt battery and this one on the fritz. Was down at 11.8volts and randomly logged a SOS call before the cabin microphone stopped working. Back at 12.2 volts after changing how I leave the car (ie switch off and unplug everything)

Had to replace a rear door handle (snapped off)

Refill coolant comes on at start and shutting down starting car clears it.

Car constantly forgets charge schedule and needs reprogrammed but never target temperature?

Strangely I still really like the car?! More so than the bmw 320d it replaced…

OK - the 'Refill Coolant' warning appeared on my 2019 38kWh car at 29,000 miles.
When I re-started, the warning did not reappear.
I wasn't planning to do anything about the warning because I am (patiently) waiting for the full battery replacement recall.
My understanding is that the coolant will be replaced during the recall thus saving me the expense at the 40,000 mile service!

Your coolant is possibly fine if you have followed the maintenance schedule for the car.

Mine started coming on after the 30k service and restarting the car clears it. I checked the levels and it was fine. Unless the sensor can tell when the coolant is no longer in good condition and it isn’t a simple level check?

I wonder if it is to do with my 12volt battery being kaput as that seems to create all sorts of glitches….

This whole issue is crazy. As I have posted earlier. This has been happening on and off with me for a few months now. What normally happens is sometimes it comes on when I start the car so before moving etc I switch it off and then on again and the warning goes off and stays off. Surely, this is an electrical / sensor issue and nothing to do with actual coolant or levels etc? The Hyundai garage say that I have to bring it to them with the light on as there is no log of it. This is virtually impossible as there is no consistency to it!

My car does exactly the same thing. Low Coolant level keeps coming on. It's going back for its 5th visit to try and fix it. They said they need it in for a few days to do multiple flushes of the system. (This will be its sixth time to try and fix!!!!!!
They did try updating the car to the latest firmware on visit 3 but that introduced another issue of the relay behind the passenger glove compartment Clicking for about 10 seconds every time the car is started and stopped. Reading another thread, I know what this might be now and can tell the dealer to fix this at the same time, I hope.
This all started around 39,000 miles.

My car has had annual Hyundai servicing - last one, 3 months ago at 27,000 miles. But I am sceptical about the service having any impact on the car, as I seriously think the only area looked at was the brakes and discs!

I am showing my naïveté there thinking that they do more than just kick the tyres, pick there nose and take your money at a service 😬😬😬

Charged my battery using a ctek charger today and the negative terminal clip was lose and inside dirty.

I am kind of hoping my coolant refill light is related to the battery issue.

Largely because I see what others are saying and hope I can avoid multiple visits and no joy.

It is really disappointing that dealers etc seem to lack technical expertise in the vehicles they sell / service.

Had similar with bmw and bro same thing with Audi..

Just thinking out loud here :cautious: given that quite a few Ioniq 38 and Kona owners suffered the fault quite soon after a service?

I wonder if uniformed Hyundai service personnel are topping up the coolant with the wrong type of coolant, mixing normal antifreeze with this new expensive wonder coolant that is no longer electrically conductive?

The first time the refill coolant warning came up was in October 2021(Approximately 42,000kms), it would come up regularly and in November the dealer serviced my vehicle but couldn't replicate the fault and asked me to keep an eye on it.
The battery was replaced in December 2021 (47,000kms) - So it's unrelated to the issue.
The second time the refill coolant warning started appearing was in January 2022 (49,000kms), the dealer carried out an 'electronic flush' which cleared the fault
The third time the refill coolant warning started appearing was April 2022 (50,000kms), again the dealer flushed the system and said they had now put in a new special coolant under technical advice from Hyundai
The fourth time the refill coolant warning started appearing was May 2022 (54,000kms), I started insisting the Hyundai replace the vehicle or refund my money, I was forced to return the vehicle for them to attempt to rectify this issue, In August 2022 under technical advice from Hyundai they 'triple flushed the coolant system with hot and cold water'.
The fifth time the refill coolant warning started appearing was just now in September 2022 (60,000kms). The dealer is reporting the issue to Hyundai and looking for technical direction.

Hyundai Australia say the fault is isolated to my vehicle, which clearly it isn't. They also say that each time the dealer has been able to rectify the issue as the fault does not return immediately, so in Hyundai's eyes it's deemed as being repaired.

I'm told the pump rpm is what the car uses to detect the low coolant and when it exceeds a certain value (I believe to be 2,500rpm) it triggers the warning. The car has also had the pumps replaced and several hoses which as per above has not resolved the issue.

I've noticed that the first time the fault appears the vehicle ambient temperature is 21C, the fault starts with an occasional appearance resetting when the car has been off for a long period but it steadily gets worse until it appears every day. For me the fault usually only appears on the second occasion I use the car each day, but then will stay on for the remainder of that day.

I'm now lodging a complaint to Fair Trading in Australia as clearly the vehicle has an issue that cannot be rectified. If you have the same issue with your Ioniq, please get in touch so we can arrange a class action and get this sorted out.
Hello
We too are having the same "Refill Coolant" problem - for close to 2 years now with 5 returns to the dealer for flushes and one new coolant pump and still the message reappears so I think a class action to retrieve our purchase cost must be a possibility if Hyundai can't fix the problem. I have emailed Customer Service several times without receiving a response but from this forum it is clear the 38kWh Ioniq has a big problem. I believe the Kona may also have an issue but that is not confirmed. I am in Brisbane and deal with Keema Hyundai Mt Gravatt so keep me informed as to the response to your post. Thanks Joey 2022

A quick update from my end, Thanks to a bit of legal bantering and a letter of demand, the local dealer has requested to have my vehicle for a full week to run some ongoing tests for Hyundai. The car has been flushed 6 times in the past, the pumps, battery and several hoses have been replaced but the problem returns roughly 4 weeks after the last flush.

As it's been explained to me, there is a temperature sensor in the battery that turns the coolant system on and off as required, but this is not related to the refill coolant warning. The warning is generated by the rpm of the coolant pump, with the trigger point being 2550rpm. If your pump goes over that, the warning appears.
Hi Silver wheel
we too have had the Refill Coolant problem with numerous flushes and one new coolant pump. Please get in touch as another owner is looking at a class action and this might be a possibility as this problem will not go away Thanks Joey2022

Hi All,
Thought I'd provide an update on where I'm at with this ridiculous problem. I lodged a complaint with the department of fair trading (that's the first legal step you can take in Australia to getting compensation). Hyundai reached out and said they had just become aware of my case (despite about 20 emails and 10 or so calls from me to their 'customer care centre') and were looking into it and would be in touch within 48hrs to discuss it, then radio silence. Fair trading got in touch as asked if I would accept a face to face with Hyundai at the dealer to discuss a course of action, which I gladly accepted. The dealer also asked if I could return the vehicle for Hyundai to bring their specialist technicians on the day to test and confirm the issue.

Last week I was contacted by Hyundai to say they would be giving me a loan car today at the meeting (EV Kona) and to pat themselves on the back for being so amazing at helping out (note the sarcasm) and that my vehicle would be looked after.

At the meeting was to be: Myself, The Dealers Service Manager, The Fair Trading Representative and The Hyundai representative. The Hyundai representative decided to appear 1 1/2hrs late to the meeting, attempted to give the keys to the Kona to the customer service counter and leave without even speaking to the rest of us. Fortunately the service manager cornered him and forced him to come talk to us. When he entered the room, he identified my and literally through me the keys and said "I only found out about this case late last week, it has nothing to do with me, I'm just here to drop off the vehicle" at managed to get a few words out and confirm that there was no Hyundai Specialist technician coming nor did the guy care about what was happening. As he exited the room, he said "by the way the car needs charging" and left.

The arrogance of this company is almost incomprehensible, my statement is simple to any one reading this: Under no circumstances should you ever by a Hyundai Vehicle, that is EVER, for ANY reason! Do not buy any model of Hyundai!

The dealer now has my car, they confirmed that their instructions from Hyundai are to flush the vehicle again and hope that it fixes the issue. If you've got this far through the posts on this topic, you'll be aware that this will not fix the issue.

So I have no referred my case to NCAT (next step after fair trading) who has the authority to make a financial notice against Hyundai should they feel there is enough evidence to warrant it.
Hi WarwickR Please get in touch as we are likely to follow your lead and complain to Fair Trading. Thanks Joey2022

Yet another update from my side.
I'm told my vehicle is off the Hyundai graveyard. I returned the vehicle a few weeks back to the servicing dealer, where we were supposed to meet with Fair Trading and Hyundai to discuss and resolve the issue, except the Hyundai Australia representative chose to not turn up. I was given a loan vehicle (EV Kona) while they were attempting to fix my car, which I have now had for 3 weeks.
To be honest, the dealer has been exemplary, they have communicated with me regularly to let me know what Hyundai Australia was asking them to do and what the outcomes had been at each point. Hyundai on the other hand have been the exact opposite, I'm having to chase them down every step of the way and constantly get 'we are looking at what the best options are for you we'll contact you tomorrow to discuss' and of course they never do.

According to the dealer - Hyundai believe that there is a crystal formation occurring in the coolant system (Which there definitely is). The crystals start to block the coolant flow, which starves the pump, causing it to cavitate, which then allows it to overspeed and trigger the coolant refill warning. Each time my vehicle has had the coolant change they have had cupful's of crystals. Even with the change in coolant types, battery replacements, pump replacements and everything else they have done the crystals keep returning.

This time Hyundai had the dealer disassemble the entire coolant system and flush each component in both directions. After each flush the dealer had to report on if any crystals were found. Over a period of 3-4 days they kept reporting crystals coming out of the system. After a week, Hyundai asked the dealer to re-assemble the vehicle and they would arrange for it to be towed back to the head office (that was two weeks ago and the car is still sitting at the dealers).

In the same time line, I was contacted by Hyundai Australia because of the legal pursuits I have undertaken. They conceded that it was unlikely that any amount of flushing is going to permanently rectify the situation and after a few weeks of back and forth they are now offering to refund the full purchase price of the vehicle. Based on my experiences with Hyundai Australia to date, I feel I will be fighting all the way to the end of this process for it to actually occur. At this stage they have proposed it will take 3-4 weeks to complete.

The fight continues...

Thanks for the detailed explanation of your issue - I really hope that isn’t happening in my case.

Did you refill coolant light reset if you “rebooted the car”?

Is the fair trading authority quite powerful / competent in Australia?

Good luck with getting your compensation / refund.

Each time the warning started it would come up occasionally, then steadily get more frequent until it came on every day. I usually found it would reset with a reboot the first few times, each time the issue reappeared but as the problem got worse that would stop.

Fair Trading is pretty good here. It's a bit of a process but it's the best we have. The system is designed to be used without specifically requiring legal representation which makes it great for the average person.

Basically you lodge your complaint, they'll contact both parties and attempt to mediate a resolution, failing that they refer you to an arbitrator who will listen to both sides and make a binding ruling. If someone plans to bring legal representation they must advise the other party before arbitration so you go in knowing what to expect.

In Hyundai Australia's case, failing to turn up to their meeting with Fair Trading and I was a very poor decision on their part.
