Went to the service yesterday (45000km) and told them about the "refill coolant warning" issue. The guy found out that the recall was issued recently by Hyundai about this. However, since only like 500 e-Ioniqs were sold in my country overall, he wasn't specific and also told me that car would be ready today afternoon. A mechanic called me a while ago telling me that the procedure is not that easy and that the car will be ready tomorrow afternoon, but he did not sound certain about that at all. I don't think dealers have any experience with this issue here, will keep you updated (Coolant used and the outcome, cause if this is a recall action, it should include flushing the system and changing the coolant for newer one.

Hi,
I have a 38 kw 2020 as well.
I'm at about 40,000 km.
Just got the error this morning.
Reading this thread actually terrified me...
I have always boosted to people with gas cars that Electric cars don't break down. No I see a problem that no one in this forum could solve.

Has there been any definitive answer as why this is happening and what we should do from Hyundai? Is there going to be a recall?

I'm living in Denmark and it is almost impossible to sue anyone...

The problem is solved. I know the thread is very long. But it is solved. You shouldn’t need to sue anyone. Hyundai is aware and has a campaign to fix it (note that it doesn’t look like it is a recall at present). Some of us have had that recent fix with the new machine doing the flushing, including me. And since I had it done, I’ve not seen the issue again.

Also, from what I understand, your car won’t break down. It doesn’t refuse to drive. It’s just a warning.

Call your dealer/retailer, explain the error and if they’re not sure ask them to contact Hyundai directly who can advise them.

Wow! That's great to hear Leafocaster!
Thank you for the good news 😊

Ok, so my car was serviced (3rd service - 45 000km) plus the campaign stuff under warranty including flushing the cooling system and replacing the old blue BSC-1 coolant with new one. New coolant has the same blue colour but its name is BSC-2.
Don't hesitate to call your local hyundai dealer, they should know about the campaign by now and it should be free of charge for Ioniq EV owners.
I have driven some 400 km since the coolant change and so far so good, let's hope that this will solve the problem for good.

OK - finally, I have written evidence to support my battery change - completed late December 2022:-

Complete Recall 11D044 - Replace high voltage Battery System Assembly (BSA) and update software logic - 5.4hours
Parts:
 Battery System Assembly - 37501-G7650AS
 Low Conductivity Coolant - LP040APE02EVH0 x3

Ioniq 2020 22,000 miles on the clock, coolant level was slightly below minimum, no warning though but Hyundai dealer very efficiently topped up the coolant for free under warranty, a month on, the warning appeared "refill coolant" randomly but progressively more frequent, now every time I start the car. Coolant level same as the rest of the comments on the list, normal between max and min.
Messaged Dealer waiting for reply, extremely disappointed as Ioniq EV's had great reviews on reliability but having spent a lot of money on a nearly new car I didn't expect these frequent issues and having to drive miles to dealer so often to resolve.

Hi
I just got the Refill Coolant warning today on my 2020 electric after 40k. From what I gather it's a closed system and can't be topped up manually and I should take it back to the local Hyundai dealer? I'm in Australia, will this be covered under warranty?
Thanks.

Check if the level actually is low or not. If so, the dealer will simply top-up, job done (in their eyes). But you may well get it again soon, in which case you need the Coolant Replacement Campaign done by the dealer. This needs a special bit of kit he may not have, and takes a few hours to do. All this should be done under warranty. Read this thread.

 

[alsiik]

Bottom line: Hyundai dealers should all have the equipment necessary by now.
As Andy put it:
1) check the coolant level
2) also check if there’s some jelly-looking coolant stuck in the coolant tank (I had less than minimum amount and could see the jelly stuff)
3) contact any H. dealer, should be replaced free of charge under warranty.

 

[andy_G]

Contacted dealer, if u get the warning and level is normal then there is a recent recall in Uk which involves I think flashing the battery cooling system, replacing the high insulation coolant with a newer type? And updating the main software, dealer wants the car for a day, it’s done under warranty

Thanks. It's just below minimum. I'll book it in at the dealer. Although I don't really trust my local dealer (Castle Hill, who is new to IONIQ EV servicing), as when I took it in the for the last service they couldn't even update my firmware, said my current one was the latest when I could clearly see on the website it wasn't. Had to upgrade it myself.

 

[HandyAndy]

Hmm, that's unlikely to be low enough to trigger the alert! What happens is the pipes get clogged so fluid doesn't flow, the pump motor spins without managing to move fluid so it's doing no work & overspeeds. This overspeed is detected, and the assumption is that there's no fluid around to be pumped, therefore the level must be low. Ask yr dealer if they've heard about the Coolant-swap campaign ... ! And if so, have they got the special flushing kit yet?

Thanks. I assume the car is still safe to drive though? Although if there is no actual coolant flow to the radiator then it may as well be empty.

When you see the error, try turning the car off, waiting a few seconds and then turning it back on - that method always worked for me while I was waiting for the dealer to fix it.

It's been constantly on for a few days now, doesn't go off.

Mine looked just the same, especially the upper part where you can see the blue stuff starting clogging.
Used the car in everyday driving though, it might have affected the rapid charging speeds but I'm not quite sure about it cause there are so many things (outside temp etc.) to be 100% sure.
After changing the coolant I got nice steady 35-40 ish DC rapid charge this weekend while charging from 35-74% SoC but again, it might be because of the rather spring weather atm - temperatures of 12°C.

 

[HandyAndy]

I don't know if the coolant is for the battery only, or whether it's cooling the motor as well. Whatever, makes sense to not thrash the car hard if the warning's showing! A steady 60 on a dual only takes about 10 kW of power from the battery, and the motor's peak is 100 kW for a few moments of maybe a minute or 2, so that's well below the kind of continuous mountains/hills stuff that you'ld expect to need cooling. Mine's been fine with the occasional meassage popping up, nothing broke!

Gge has just finished swapping my battery & flushing the cooland at the same time, 8 a.m. yesterday to 11 a.m today to complete both jobs. It's now charging for a few hours filling up, so I'll get there about 3 ish.

Hi Guys,

A member of Australian FB ioniq group reported they had coolant changed to "BSC-2" twice under the same service campaign code TSB 20D140.

Low coolant warning returned after 6000km and again 3000km later.

Thoughts anyone?

 

[HandyAndy]

Feedback after getting my Coolant swapped out, at same time as a Battery Swap under the Recall.

The new fluid (BSC-2) is Blue. So anyone in here who got pink stuff in their 38, has presumably got the wrong stuff.
I quizzed the mechanic I spoke to, but he wasn't clued up on what the pink stuff's for, or whether the Ioniq 5 uses it.
Mine was done yesterday & today by Richmond Hyundai in Portamouth, and was also the 2nd Ioniq battery swap they've done.
On Monday they also did an Ioniq 38, the first of this model they'd battery-swapped, and they had a techhie freom H to come & supervise the process. That car also got the full flush + coolant swap treatment.

They had mine from 8am yesterday to 11 am today, then they put it on charge & I picked it up around 3 p.m. with just over 50% SOC in it. As far as I can tell they know what they're doing, and have done an ok job. Time will tell!
