i agree on the reservoir refill. however, i would like some kind of tool like a coolant specific gravity tester. then one can see how contaminated it is. drain/refill until near new specific gravity is achieved. reminds me of transmission fluid, half stays in the converter, but drain/refill does replenish entire fluid so it is still good. brake fluid can be done the same way, power steering fluid, coolant, why not the low conductivity coolant?

If you watch the video above you will see they extract almost all fluid before refilling. Ithi di something I don't think the shop down the road will do.

i did watch it. in real life, coolant, atf, brake fluid and power steering fluid can all be serviced by drain/refill thru the reservoir. if there is some way to determine how contaminated the fluid is, then it can easily be refreshed by the drain/refill method. like oil changes for gas engines. every time i sent a sample to blackstone, it would come back as still good for much more. not all cars are the same

I did get mine done to the tune of $1,000 on Monday, 3/10 but it wasn't without a hitch, (and this is at a reputable dealer). After 3 hours, I was given the keys to my car to drive home only to find my instrument cluster telling me "Refill Coolant". Went back in and they checked it out determining that there must have been a bubble in the system.
Next day, drove the car to the Y in the morning and when I left there, I had the same message. Looked into my frunk and saw the blue coolant reservoir empty. Called the dealership and went back down. After another 2 hours, got the car back and so far so good. Mechanic just said that the system is very sensitive. Hmmmmm. Anyway, all seems good right now. I guess the moral of the story is this may not be something you want to do on your own if the professionals are having issues with the procedure.. Between 4 12 volt battery replacements in one year and now this, I'm starting to second guess my purchase. I absolutely love the car when all is well but it has been a challenge.

€530 when mine was done several months ago.

I called Red Rock Hyundai in Grand Junction CO yesterday. Over the phone they quoted me a cost of $375 to flush and replace the low conductivity coolant in our 2022 AWD Ioniq 5.

I just got back from service where Hyundai performed the coolant flush. That and a full 40k mile service cost right at 200.00. 2023 Ioniq 5 sel rwd.

Just kidding. I just paid attention to the video the dealer sent me and they are draining the wrong coolant. I don't think they know the difference between the two coolants

I spoke with the Service Coordinator and sent her a link to Ioniq Guy's video on LV Coolant flush and she confirmed that, even though she placed the proper coolant on the tech bench, the technician failed to flush the LV Coolant. I am taking it back tomorrow and she said they would take care of me.

I have a great amount of patience for anyone in customer relations and am confident this will get resolved.

In many EVs, coolant replacement requires that a vacuum be pulled in the system before refilling, to prevent any potential air-filled voids. It would appear that in the replacement process performed above, either the vehicle didn't require it, or the tech didn't do it. (It's quite a hassle to do.)

 

[Ferg5]

Hyundai has an air pressure tool to remove all coolant similar to blowing out irrigation system for those that live up north. And a vacuum side to use atmospheric pressure to fill the system. I doubt many shops will use such a system.

I just scheduled my appointment at Roseville Hyundai in the Sacramento CA area - $248. Not bad, considering their sister dealership in Folsom quoted me $600 a couple months ago.

I asked about the other coolant system (pink), he said it's recommended to be inspected/flushed every 30k miles. When I mentioned I hadn't done that one, he said they would take a look, but it's not as important as this one.

Wait, i need to replace the standard coolant at 120k miles? Imagine that, someone at a dealership didn't know what they were talking about when it came to EVs...

Astonishing, isn't it?

I'm not very thrilled with the "After that ..." interval.

I just had the LCC coolant flush done at Temecula Hyundai in Temecula, CA.
When my regular dealer, Hyundai of El Cajon quoted me $900, I called all the dealerships in the area. The quotes ranged from $1100 to $500 to $260.
I called Temecula Hyundai to get the $260 quote. But I knew that was wrong and kept telling them EXACTLY what I needed, but their service manager kept coming back with $260. So I called back again a day later to confirm and they quoted me the same thing. Then I asked them to email me the quote so I had it when I brought my car in. (Temecula is over an hour drive away for me.)
Of course when I got there today (a few weeks later from when I got the quote since that was the first available appointment I could make.) The service manager that emailed me the quote told me, the EV LCC service is $379. I showed him the e-mail he sent me and he denied sending it to me and said that $260 is for a non-EV coolant flush, but his email said "2023 Ioniq 5 LCC Coolant flush is $260."

So he honored the $260 price even though he kept explaining to me that the coolant cost alone was close to $200.
I know that! That's why I called twice to confirm and got it in writing too.

Anyway, it took them about 3 hours to do the service.
When I got back to pick up my car, the guy driving my car up to return it to me drove up to the front of the service dept. and I walked towards the driver's door. As he opened the door, a flatbed tow truck was driving the opposite way after dropping off a car and the guy opened the door into the flatbed as he was driving past and dented the door!

At least I was standing there right when it happened so there was NO denying the fact that he caused the damage.
The service manager came over and they called their body guy in to come fix the dent/scratch.
It only took them a couple hours and, to their credit, it looks perfect. Can't even tell where the damage was.

So all in all, I think they lost money on me, but that's all on them. Not my fault...

I got my coolant change done at 40K to the tune of $1,000. Brought it back the next day due to the "Refill Coolant" warning on my screen. Reservoir was empty. Got that straightened out and now 3 weeks later, have the same message popping up. Reservoir is now about 1/4 full. I don't know why this is happening but I suspect the dealership doesn't know what it's doing with this job. Very discouraging.

WOW! It takes a long time to do a job when you have no clue how to do it. Hence the insane price.

 

[justdoit.shattuck]

I don't know if that's the reason or not. I've seen prices all over the place from $300 to $1,000. Unfortunately, I ended up on the higher end of the spectrum.

i think that is because that dealer is not using the machine that hyundai has for this it is a lot like coolant on a gas car. for some cars, it is a real challenge to get all the air out. cars with v engines have problems. i have a kit, uview airlift that made the job foolproof. just like the hyundai machine, it would suck out all the old coolant. this would put the system in a vacuum. then, fresh coolant would be sucked in to fill, and there were no air pockets. no need to warm up, cool down, refill. when this came out, it was a game changer.
