Would you mind sharing the service campaign notice no and details when you get hold of them please?

Thanks

Hi Kousuke. I wrote to my dealer right after your question if they could provide me some information or link to a website with more about the service campaign. They called me afterwards and told, again, that there is a service campaign on the issue but it "so new" that there is no public info on it (their words). He assured me that the work done would be free of charge (maybe thinking that was why I was worrying).

I then asked for him to write what he is saying to me on the phone to have some sort of history/proof of the issue. Here is the translated email from the dealer:

"As I said, Hyundai is running a service campaign on ''refill coolant''. This campaign means that the coolant on the car must be replaced with a new variant. This is done using special tools that can correct the problem. We have not received the special tool yet and therefore cannot carry out the repair at this time. Once we receive the special tool you will be contacted so we can make arrangements."

Many thanks for the update - very keen to get the service campaign no. or any available details.

Please keep us posted when your vehicle has completed the service campaign.

Well, so far I have had multiple flushes, a pump / foil update done, a new HV battery and last week they replaced the radiator. Picked up the car on Friday evening, didn't put it on charge that night and the next morning the light came on again. :mad:
They also are refusing to give me documentation of what they actually did.

My car has been with the dealer since 5th December 2022 for the Low Coolant level and two other faults. Clicking relays and Charge Plug not Locking in place.
They say that everything is fixed except for the coolant fault.
Sadly No indication of when I will get the car back.
Clearly flushing the system doesn't fix the problem as my car must have had multiple flushes.
When I get it back I will try and get as much detail as possible of what they have done and post it here.

As a Kona owner, I've been following all of the main Kona forums expecting this to show up and the closest I've seen is a Canadian owner's complaint about "a rapid loud clicking noise which stops and starts" immediately after a scheduled coolant change. There are no other reported symptoms and the dealer is still working on it.

Do you have the 38 or 64kWH battery in the Kona?

My Ioniq now has pink cooling fluid.
According to the dealer they drained the blue fluid, cleaned the cooling system and refilled it with the new stuff. They say, there is an advice from Hyundai to do so.
At the moment, the coolant warning hasn't reappeared.

Since my Ioniq was the first car with this issue at the Shop, they are as curious as I am, if this is the final solution.

And yes, they definetly used enough coolant.... ;)

As best as I'm aware the pink coolant is the current standard conventional ("HOAT"-type) coolant for all Hyundai ICE. My Sept-2018 Kona had this installed after the battery recall but it looks red ... I suspect because of mixing it with green coolant. I think it's a good solution to the problem and presumably the change interval is now far longer.

Presumably this is mixed 50/50 with water, so bang goes the "super-low-conductivity" feature/protection of the previous super-expensive coolant? I assume also that the 4-yearly fluid change (if H carry on doing this) will cost a whole lot less now?

With a bt of luck, if there are any crystals gumming up the pipes despite multiple flushes, the water in this might disolve them away, problem solved?

They said, there is an advice from Hyundai to replace the blue low-conductivity-fluid with fancy pink even-lower-conductivity-fluid.

Because all this was paid by the warranty, I did not geht a bill, or some other report.
So I don't know if the pink fluid is really something new an special or if it's standard-coolant.

If you can, please inquire as to which (model number) fluid was used. So we can check to see if they are just reverting back to ICE coolant (which is much more cost effective) or if it is a new "even-lower-conductivity-fluid" as you were told.

OK - I've had the 'Tilbury' (UK) treatment - allegedly, traction battery replaced and coolant flush/replaced. The whole process took 3 weeks and there was precious little communication - except at the end when Tilbury phoned me to say the car was ready for the AA to return it to me. After that, I heard nothing, until an AA person phoned me (3 days later) to say he had dropped my car at my road end . . . on a very dark, wet night - I didn't feel inclined to do a thorough inspection.
Image

The coolant in my car is BLUE - done by Tilbury in 2023 - (and as you can see - filled well above the MAX line) - so make of that what you will. I have asked on 2 occasions for a list or summary of the work completed in Tilbury - and am waiting for a response.
This experience has not enhanced my opinion of Hyundai because in answer to my question "given that the battery and coolant was changed at 30,000 miles - does this mean the coolant change at 40,000 miles does not need to be done?" Answer (from Tilbury): "you will have to check with your servicing garage". As if a garage would turn-down the opportunity to charge £450 for topping-up the coolant . . . .(excuse my cynicism).

This thread is a great resource for all IONIQ owners. Thought I'd help out the convo and add what happened in my situation. Over the course of 1.5 years, I took my Ioniq into 2 different dealerships for a total of 3-4 months of service, and they never fixed the problem. So I contacted HMA and worked through their customer service line, and they deemed my case eligible for a lemon-law buyback. I waited for a month for the offer, and when I got the offer, here's what it boiled down to.

My cash in (down payment plus payments) was about $30K (USD). My car had 30,195 mi on odometer at the first service appt for this issue (yes, this is important), and as such, they calculated a mileage deduction of $9,260 from $30K and they would pay off my remaining debt from Hyundai Finance, leaving me with about $12K. Overall, it was an OK deal, however, at the end of the day, I decided to keep the car instead of sell back. Since I decided to keep it, they offered me a $5,000 cash settlement.

In addition, one of the dealerships in my area figured out the appropriate coolant replacement for the error, so I decided to keep my car, take the 5K cash, and get the error fixed. I did this primarily due to wanting to pay off other debt sooner, and if they could fix the error, then it was a win-win. Additionally, I think I can sell my car on the market right now for around $20-25K, which means that I potentially could end up making more money this way than if I had sold it back to Hyundai.

Do any of the informed contributors to this thread know what temperature the cooling pump kicks in? I have a theory that the crystallisation and hence fluid shrinkage results from the fluids exposure to higher temps. There seems to be some correlation between the coolant alarm occurances and milage and higher ambient temps ie Australia, US and Europe. I have noticed that the alarm in my car only comes on after a period of rapid charging and that the fan becomes audible when the charge rate climbs to 40KW. I've also noted that the sweet spot of 40KW charging has shrunk from 30 - 70% to 40 - 60% which I presume is a related effect. My car 3 years old 26K miles and operating in a relatively cool climate
