If it's what I think it is, it's new so report back with the campaign number if you can.

 

It's Campaign code: 20D140

 

I have seen this recall mentioned on a French Kona forum. Seems to have only cropped up in last week or so.

 

Put your VIN into Rückrufe und Serviceaktionen | Hyundai Deutschland
It says my Kona is affected:

 

Yes, confirms against the VIN for mine.... Wonder how widespread the recall is as sounds like they weren't aware of the recall when I booked it in for service..

 

Yep have a Ioniq 38 which is affected with this. If it's severe enough you will get a 'Refill coolant' message on the dash.

From the reading around I've done on a couple of forums - it's apparently the coolant crystallising somehow. There seems to be mixed messages as to which coolant it is replaced with however.

 

I have an e-Niro MY20 which also had the recall done a couple of months ago. Lots of people in Spain have had it done as well.

 

Do you have a recal number for this please?

 

I don't have it but someone mentioned it in post #3

 

Thanks , I noticed you had a kia and wondered if the kia number was different

 

This is a Campaign, not a Recall. So it gets done when you have a regular service that has a scheduled coolant swap anyway, and they'll charge you for that so it's an expensive one. If you get the coolant problem error-messages popping up, they should fix these under warranty. At least H did on my Ioniq 38 which started getting the warnngs last winter.

They aren't going to automatically recall all the cars with the early BC1 coolant in them, as why change it if there's no problem with the car?

 

And yet the website says to contact your dealer as soon as possible.

 

It might be because it's not explicitly a safety issue. But it's likely in Hyundai's best overall interests to get this taken care of as quickly and quietly as possible.

 

Cannot point to info but understand that some Mercedes EQC had an issue with coolant liquid “ gelling” so it had to be changed. my car has standard Mercedes pink antifreeze as found in any ICE.

 

Just had my Kona serviced, including the campaign recall. I queried what they were going to do and they said that the coolant isn't being replaced, its being pumped through a filter to remove and debris, anyone else heard this?

 

Did you have to pay for this procedure @Elevonic?

I would also be interested to know if your the speed of your home charging increases as a result.

 

Has anybody got any official documentation for this campaign code: 20D140? I've emailed Hyundai a few times but they haven't replied, and my dealer still says it's only a check. Thanks

 

My understanding is they'll only do the Campaign if the customer has a fault with the car, i.e. "Refill Coolant" message appears, AND the coolant level is between the Min & Max levels, proving the Coolant does NOT need topping up. If yours is a bit low, call in & get the dealer to topup under warranty, only takes 5 mins to do. Then wait for the next warnign message, preferabl take a picture showing vehicle mileage (so you can't have used an old pic!), & go back to dealer get them to do the Campaign to rectify the fault.

If this fault applies, as it did to me, they do the Campaign & it's zero cost to customer, H picks up the bill under warranty.
If it doesn't apply, you wait until year 4 service.

I believe they'll apply the Campaign automatically when the car's due the next Coolant change, namely year 4 service for ?all? of us involved. (May apply to year 8, if any affected cars of that age around?). And when it's done at the service, they'll charge you a fair bit extra for the BSC-2 coolant used, I guess the same cost they'd have applied for the BSC-1 old stuff. But if you haven't had the "Refill Coolant" error, for all I know they might simply drain the old coolant & refill with new, maybe leaving some old crud around. So we all need to be aware of this possibility, and insist dealer does do the full time-consuming flush&clean in full.

As mine got changed a couple of months ago, and yr 4 service is due in September, this means my new BSC-coolant will be < 1 year old. So we're pressuring H to accept that it's wasteful to change the coolant again, so soon. Please see here! Coolant Replacement Campaign causing waste...

When I get my yr 4 service done, I'll insist they do NOT change the Coolant. This stuff has a 4 year lifetime, I intent to get 4 years use before changing it. Which will be at yr 7 service, at this point the car's out of wty for the usual 5-year stuff anyway, won't be worth a lot, and I'm happy to take the risk.

 

I see from the German site my 2020 Kona has sprouted another service campaign item but it looks like it may just be a software update. Guess I should call the garage and check whether they'll automatically add it to the service booked at the start of next month:

AE EV OS EV eCALL CONTROL LOGIC IMPROVEMENT
Valid until: 30.11.2025
Campaign code: 30D042

 

My Kona EV received its expensive second service this morning. I had to wait 3+ hours and they told me that the coolant had taken longer than expected to change. The silliest thing is that the service sheets show nonsense items that only relate to ICE vehicles! You would think that for the prices charged they might at least produce a relevant information sheet.

So long as they don't include an invoice line for engine oil it shouldn't matter if a lot of the items are irrelevant.

 

I've just had a 45,000Km service done in Germany and this code was used: 10DC41R3 with notes that suggest that the "Coolant" system is flushed and refilled, as part of a recall. I assumed it was the Battery coolant.

 

Used the search tool and no joy.
Does anyone know if a 23 plate (old shape) 39 battery would need this coolant change doing?
Just spoke to Hyundai and the sales guy had no clue, he then "spoke" with the servicing department and came back with "the battery coolant in the 12v battery needs changing regardless of battery size"???!!!.
"I'm talking about the traction battery" says I.
Silence.
"Erm, I think it still needs doing whatever size of battery it is- its the same on ICE car; we check the battery when they come in at every service".
Not sure if he was genuinely thick or wanted me off the phone.
It was a genuine question and dictates whether I get a Kona or not.
I'm flat out not paying the equivalent of a cambelt change on an ICE every 4 years; I'll just get a Leaf or maybe a Zoe instead.
Anyone any insight on this seeing as I might as well bang my head against a wall than asking a dealer who really ought to know.

 

I'd probably ask Cleevely Mobile. They have actual functioning brain cells!

All depends whether it had the new BC-2 coolant (blue) when built, or the original BC-1 (also blue!) that will need changing.

Sounds incompetent to me. There isn't any coolant inside a 12V battery. Any battery checking at the annual service is going to be checking the 12V voltage at best.

Don't know what the coolant used in Leafs & Zoes is, but I'd expect them to need a similar coolant swap. Assuming these guys are all using a special low-conductivity mix (do NOT top-up with even de-ionised battery water!) then the articles I read on the web suggest this stuff has a 4-year lifetime. I assume it either degrades over time, or maybe contaminants find their way in somehow, perhaps permeating through flexible piping etc. As all EVs now use liquid cooling, I'd expect them all to specify a fluid change at some time.

I think the Ioniq 5 has 2 coolant systems, a tradition cheap-fluid one for air/con/heater matrix etc use, plus the 2nd one with expensive BC-2 coolant. And I think the Ioniq 6 has simplified to a single system, maybe it's all the cheap-traditional stuff (pink), maybe they've reorganised the way the battery is isolated from the coolant tubes & no longer need the pricey stuff? Not too sure about this, but there's clearly some variation between modern EVs.

Yes it adds to the cost of the 4-year services. But when my Ioniq 38 needs the 8-year service it'sll be a low-value car with zero warranty left. I plan to run it till it drops, as cheaply as poss. So I'll buy the BC-2 coolant myself (someone here has already bought some, not cripplingly expensive!) and I'll do my own change.

I wouldn't let this 4-year extra cost put me off an EV! Especially if it's one that really suits my needs.

The 4/8/12 year dealer services will use a v fancy bit of kit to change the fluid, takes a few hours & they'll charge a fortune. Instead I'll decant the old fluid from the reservoir, refill with the new. Repeat this over a few weeks/months and the total fluid will end up 99% new, and no fancy kit needed to do this. All I need to know is the volume I replace each time, and the total volume, to calculate how the concentration changes per topup.

 

Don't know what the coolant used in Leafs & Zoes is, but I'd expect them to need a similar coolant swap.

From my internet wanderings I think the low-conductivity coolant is a Hyundai/Kia thing only and was an over-reaction to the Kona battery fires, plus the fact that some crash-test EVs in S. Korea were bursting into flames some hours after the crash test. There's no question the rollout of this mid-production change has been more than a minor cock-up.

All recent Hyundai/Kia EVs have moved away from internal battery pack cooling and now use an external panel on the underside, same as VW did starting with the ID3. The Ioniq 5 has both coolant types (blue and pink) while most other H/K (not sure about the Ioniq 6) use conventional pink only. I think eventually all EVs (perhaps even Tesla) will adopt this strategy as it's just better engineering.

 

What I did not understand was that under the recall, outside of the normal service schedule, the old coolant would be drained, filtered and then put back into the vehicle, ...

Hmm, not sure I believe that! My Ioniq battery got replaced, and as I was getting the Coolant warning, the flush campaign got done at the same time. Thia was last Feb, 6 months before the year-4 service was due, which is our time-interval for coolant changes (4,8, ... year services). I do not believe they put the original BSC-1 back in! I needed a tiny topup of maybe 1/4 header-tank a week later, probably a few air bubbles worked out, and that was a dash of BSC-2.

... put back into the vehicle, that is completely stupid.

Absolutely agree.

At the year-4 service the dealer was happy to not swap the coolant, as all this had been done by them 6 months earlier! Made for a much cheaper service, and I'll get the next swap done at year-7 service. Or do it myself.
