Does the Hyundai Ioniq 38kWh refill coolant issues (a recall) cause battery overheating?
ฝัง
- เผยแพร่เมื่อ 19 มิ.ย. 2024
- Hyundai currently have a recall on all Hyundai Ioniq Electric 38kWh models where the original BSC-1 coolant (a low conductivity coolant) is flushed out and replaced with BSC-2 coolant, due to the original coolant crystallising within the cooling system. The first indication that your vehicle has this issue is the "Refill coolant" message on the dash. This only affects the 38kWh model (2020-2022), as the previous 28kWh model (2016-2019) does not have a water cooled battery pack.
My 2020 Hyundai Ioniq 38kWh has this issue and is booked in to have the recall work done, but the dealership had a 3 week lead time. So in the meantime, is it safe to drive? I was wondering if the deposits left by the coolant crystallising would hamper the cooling of the battery pack. So in this video, I try to test this. I did a two hour motorway drive and checked the battery temperatures and then again after another one hour drive and a 40 minute DC rapid charge.

Thank you for your test of Hyundai ionic 38 kw I have wanted to do this test I but do not have the tools. My car is going in for a third cooling issue. Great video
Google search"
The valves have three modes: Heating, Low-Temperature Radiator, and Chiller.
“During much of the year in mild climate conditions the thermal system typically starts up in LTR mode,” according to the article, “which circulates coolant through a single interconnected loop to warm the battery up to its optimal operating temperature when cold and to maintain that temperature with the help of a radiator and fan.”
Thanks. I would guess then this is actually just the radiator at the front of the vehicle then and the LTR temperature being reported in the BMS is the water temperature as it enters the radiator (i.e. before it is cooled down) or maybe the temperature as it leaves the battery pack. On our other Ioniq when I tested it, the battery cell temps were 28-29 degC, yet the LTR temp was 42 degC.
Thanks that’s reassuring. I haven’t seen the refill coolant since the TSB was carried out although I did have to get the coolant topped up a month afterwards and it has dropped again to just above the minimum line but seems to be stable there. Will see what happens in Jan 24 Y4 service when the new coolant is thrown away and refilled at the insistence of Hyundai customer services to maintain the warranty.
I have an Ioniq with this issue, it disappeared for a while after service, but came back in a couple months. I've found that for the most of the time, the error will clear after a reboot of the car, meaning it cant b e related to any permanent fault, as that would persist through a reboot, with crystallization still being there. It happens more often of the car is parked at a certain incline, and can be completely avoided at another incline, which makes me believe it is a sensor issue more than anything else, crystallization wouldnt change much depending on parking incline. Since I am not planning to sell the car, I will just keep informing them about this when it goes in to service, and hope they find a better answer than their current one
There isn't a sensor. Apparently its by the water pump speed.
I had this issue on my Ioniq too but never really told what the issue was so very interested to learn about it here. Had mine on lease and loved it so looking to get another one used as they are a bargain.
Yes, they are currently way too cheap. Even cheaper than the hybrid.
Great video Matt and FYI,
I got the alert for it too 👍🏼
Thanks
Just wanted to say thank you for all the videos and details you’ve created over the years for the Ioniq 😊
I’ve just purchased a used Ioniq and hope to collect it next week. Thanks to your videos I called the local Hyundai dealer about the coolant recall and found the Ioniq I’ve purchased still needs the recall done, as such it’s now booked in for them to change the coolant next month.
Your videos helped me to decide an Ioniq was the best value second hand EV for me and I can’t wait to get it!
Thanks again it’s been really helpful 👏🏻
Glad they helped. Also get the SOS recall done at the same time. They should do it, but just check. Some dealerships are better than others at checking.
Plenty of other Ioniq videos also filmed, now I'm driving one myself again and will be released on the channel over the next few months.
@@GoGreenAutosThanks so much I will do 👍🏻
They did mention there was a another recall - I’ve written down Logic Control Unit (although I might have picked up what they said wrong lol) but I’ll make sure to ask about this so it won’t get missed.
I’ll definitely be watching the other videos too - it’s my first EV and the ones I’ve watched so far have been so helpful 😊
@@RickyG84 Yes I think that's the SOS recall. To my knowledge, the Ioniq hasn't had any others yet anyway. All the Ioniq videos are in this playlist th-cam.com/play/PLW0oq-rvufntC8Qk6ONQjJ7nncwqhp9LL.html and new ones will be added as they go live in the future.
thank you
Thanks
Thanks Matt . Reassuuring to know and really impressed with my Ioniq and its abilty to be efficient. Getting over 200 miles per charge. Going to book in for a health check that Hyundai offer so interested to anyones experince of this
The health checks aren't worth the paper or video they produce! Its just a quick once over and really only checks the tyre treads. They don't even take the wheels off to check the brakes.
@@GoGreenAutosso that's how they diagnosed my rear brakes and pads need replacing then. The video I got wasn't sync-ed properly so I had to look at it multiple times before it started to make sense. Stupidly I presumed they'd actually taken off the wheels before filming then just shown everything in one take. They had just done the MOT though...
Matt what is your opinion on the service and MOT's plan? We're drawn by the inflation proofing and Huyndai stamp but I'd actually trust James from Cleeveley's to do a proper job.
@@judebrown4103 A service plan keeps you with a main dealer for servicing. Personally, I've never purchased a plan and never would. You'd get a far more thorough service from Cleevely Mobile. What main dealers don't do, yet charge and invoice for is shocking. Or replace items when it wasn't necessary or due to their incompetent fault finding. Yet people still seem to trust the big flashy main dealer.
@@GoGreenAutos do you know what Matt? This really has helped me get my thoughts straight! I've not trusted main dealers since Skoda 'found' six hundred quids worth of stuff that needed doing amazingly just as it went out of warranty. They might have got away with it if they hadn't tried to tell me the rear nearside shock absorber had gone when quite patently it was perfectly ok. That was ten years ago and I never went back to them.
Knowing the service was due on the Ioniq '20 plate I went to the local HEVRA garage but wasn't enamoured. Lots of certificates on the wall but their workshop was a dangerous mess and they didn't seem to understand what I was talking about which was odd so next port of call was the dealer.
They pulled up my vehicle's details on their computer, found out which service it needed and if it was subject to the recalls, it was.
They did its first MOT and they did the health check and filmed it all which I thought seemed quite transparent. Only when you mentioned that what I was seeing on the film wasn't a summary of what they'd done but was probably actually the health check did the scales begin to fall from my eyes.
James is booked up until September so I'll have to stick with the appointment for the service and warranty recalls. However I won't have the brakes and pads replaced for £324 I'll book in with James to do that in September.
I did have to negotiate the price of the service down because they reckoned its the £500 one with the coolant change which they were going to charge me even though they were doing the warranty coolant change! They still want £259 which is ridiculous but haven't got any choice at this point.
I'll get back on to James and get booked in. Can't thank you enough Matt.👍
Very helpful..
Hi there. I have a 2020 38kWh Ioniq also (I had the coolant changed prior to my first rapid charge after taking ownership of the vehicle a couple of months ago - I did it proactively under the campaign, before any warnings occurred). I just thought I'd chip in my experience:
You will definitely see coolant flowing back into the reservoir and the level will be bobbing about if the coolant is circulating around successfully (it returns to the top of the tank). I lifted the bonnet and checked this during my first rapid charge after they changed the coolant, to make sure everything was ok. (I also observed the level drop about 1-2cm initially, as they left air in my system after changing the coolant, but for all subsequent rapid charges then the level hasn't changed during circulation as the lines are all flooded).
I have never had the "front flaps" open up yet, although the radiator fan is running during rapid charges. I guess the battery never reaches a critical temperature to open them.
Thanks for your work so far. Worth checking that the coolant is circulating after they have flushed the system out - you'll definitely see it when the pump is running.
Hi, yes always welcome to chip in. Its good to hear about your experiences.
I did a video on the Ioniq cooling system which you may find interesting as I show the water pump working. Its long, but you can use the timestamps at the bottom to skip through it - see th-cam.com/video/iRIqqhYXu5g/w-d-xo.html
Thanks Matt for this great video. I researched LTR online, which means Low Temperature Radiator. I think another great test that you can do for science, is to bring your two Ioniqs (the one with BSC-1 cristallization issue and the one with the new BSC-2 liquid) to a DC charging station, at similar SoC, charge them for about 15-30 minutes and compare the temperature variation on both of them, in under the same conditions. I think a test like that will reveal if the cooling performance is degraded or not on this car, by using the other as reference. But this setup is complicated for sure, because you will need the help of another driver and it will be expensive. Thanks again very much for this video that tells us at least that the batterty pack is being cooled enough and that we don't need to worry about it overheating.
Good idea, but too late now. My Ioniq was dropped off at Oxford Hyundai today ready for them to change the coolant tomorrow (Monday).
I think LTR is then referring to the main radiator at the front of the vehicle, so I guess its measuring the water temperature at the end of the circuit before its cooled by the radiator. Its probably a sensor on the coolant exit point in or near the battery.
Thank you for this test :-)
You're welcome
Thanks Matt for the informative video, most TH-camrs don't go into this sort of interesting detail.
The fluid tank you were looking at is the coolant expansion tank. You can think of it as the filler tank, or reservoir tank. The coolant doesn't flow in and out of the tank as part of its normal circulation, much as an ICE engine expansion tank isn't used this way. The flow circuit is thus not visible.
Also, we know what you mean when you call the coolant 'water', but while it may or may not be water based, it isn't water and your viewers should not be confused that putting water in this system is not wise. Many coolants these days are not water mixes at all.
I am still worried about your MS damage, although I know it is being taken care of and can't wait to hear more about the unfortunate plight of your beloved super saloon.
Yet when the water pump is running (at full speed anyway), the water certainly does come through the expansion tank at speed, as shown when I did the Ioniq coolant change video th-cam.com/video/iRIqqhYXu5g/w-d-xo.html. Its a long video, but the timestamps allow you to skip through it.
I hope to do a Model S update video, if the bodyshop let me in!
Reminder: while the coolant is fluid, it is definitely not water.
@@AlainODea It is around 50% water
I'm amazed that the battery cooling circuit did not kick in for you when rapid charging. I wonder if it was because you were relatively high SOC when you started. I was rapid charging a few days ago and decided to have a wee look under the bonnet and, just as you were expecting, you could clearly see the water flow in the coolant header tank, and there is quite a lot of noise from the pumps when it is cooling actively. I'm assuming you were charging at a charger that could provide over 50kw. If I am charging at a Tesla Supercharger it peaks at 50kW charging speed which is quite nice. But, if I plug into a regular 50kw charger then you get a max of 43-44kW as it can't supply more than 120 amps or so combined with our lowly battery voltages!
Yes I was using a 120kW DC charger.
When I've manually activated the water pump (when doing a coolant change on a 28kWh Ioniq - see th-cam.com/video/iRIqqhYXu5g/w-d-xo.html) the water flow is quite noticeable as you say. This is why I was expecting to see it flowing around.
I do have my suspicions that the coolant channels in the pack are blocked, but then there the cells weren't getting hot. Anyway, the car is now at our local Hyundai dealer where it should be getting the coolant flush and change job tomorrow.
Great video Matt, have you replaced the auxiliary 12v battery ? I’ve read they can fail and to fit a better make than supplied. Thanks in advance for any advice.
I've never needed too and never experienced a failure either...after 4 years of running 3 of them.
Thanks for this Matt and for going to the expense of charging much more than necessary.
You've made me realise that mine makes a bit of a racket when charging and I've had the light for a much longer time. Booked in to have the coolant change, service, other recall, brakes etc on 31st July. The noise it makes must be different from the aircon pump as I don't have sit with it on, it's evening when I charge, you can hear it inside the car, I'm presuming it's a pump of some kind as it starts whilst charging which I do after only about twenty minutes on the road. Have to rapid charge as no home charging. We're going to have to keep using it because...life and elderly parent so I hope if there's any damage to pumps etc it's all covered in the warranty! 👍
You should get the air con regassed about every 3 years. All cars loose about 50g of refrigerant a year. They shouldn't, but all vehicles do and have always done due to the number of joints and quality of the rubber & seals. If the refrigerant drops too low, the compressor can be damaged and they're very expensive items on EVs as they are high voltage. So its wise to treat an air con regass as part of the your preventative maintenance, like a service. You don't need to use Hyundai though. Anywhere that does air con can do it or use the mobile services for ultimate convenience and they're probably more skilled and experienced too as this is all they do.
@@GoGreenAutos thank you for this Matt, I will look into it. I think this is one of the many things they're going to do when they've got it on the 31st. Glad they're providing a courtesy car!
Hi Matt, can you please share with me do you know how we can check the state of health of the battery this will be very helpful to me because I’m looking to buy Hyundai ionic 2020 electric.
Many many thanks in advance great video you have new subscriber! 🎉😊
You really don't need to worry about the battery. But I use a diagnostic scanner as you can see in many videos I've done about this www.youtube.com/@GoGreenAutos/search?query=ioniq%20battery
But there are apps you can use if you get a bluetooth OBD dongle.
The coolant stagnation on expansion tank is quite normal thing. The coolant circulates on lower parts of system.
Yet when the water pump is running (at full speed anyway), the water certainly does come through the expansion tank at speed, as shown when I did the Ioniq coolant change video th-cam.com/video/iRIqqhYXu5g/w-d-xo.html. Its a long video, but the timestamps allow you to skip through it.
@@GoGreenAutos Thanks. :) Your videos give me very useful knowledge package about classic Ioniq. Before buying it. Very limited cars are put up to sale, which happens when the machine is really good.
The Ioniq FL has three water pumps. The third is not in the drawings. Only marked with a star in the sheets without any ID. And that one was kaput on my FL. It was a hard job to find the right number to order this part according my bodyshop. So after one and a half year and 4 coolant refills and 2 new water pumps the error is finally done. 😃I bought a 2l bottle of the new coolant (~€36,-) and refill it time by time if the level is low.👍
Do you have a spec/grade or part number for the coolant?
Hyundai are now using "BSC-2" low conductivity coolant when they do this recall job. This replaces the "BSC-1" coolant they were previously using. The labels on the bottles do not identify the spec or ingredients.
Matt doing an almost full rapid charge on InstaVolt at £0.75/kWh as dedication to Science, taking one for the team 😂 👍🏻 Thanks for this informative video. I suspect the absence of massive increase in temperature is probably linked to the relatively slow charging rate of this 38kWh Ioniq model (~45kW in theory). Which makes me wonder if Hyundai may have voluntarily limited to this power as they might have anticipated this coolant issue due to their new battery cooling design (compared to the 28kWh Ioniq)🤨. Anyway, good to know that the car is usable.
Hello just done a load of research and picking up an ioniq tomorrow.
You say he's taking one for the team I'm guessing because the price? Am I right in saying its a 38kwh battery so 38x0.75p is £28.50 if you then divide that for say around 150miles if that's a doable range it's around 18 19p per mile which is what my audi does now 😅🙈
@@CJ-gq6ol actually, on an Ioniq, you can only rapid charge up to 94%. (100% on fast or 3-pin charging). So since you’d only realistically want to drive down to 15% of battery, we’re talking 94%-15% = 79% of charging to do on a rapid charger. 38 x 79% x £.075/kWh = £22.5 for a “full” rapid charge. This 38kWh Ioniq has a winter range of 155 miles/249 km (actual 130 miles/210 km, 100%-15% of battery) and a spring/summer range of 180 miles/290 km (153 miles/246 km 100%-15% of battery). So 94% down to 15%, that’s 122 miles in winter and 142 miles in spring/summer. So £0.18/mile in winter and £0.14/mile in summer if you only rapid charge, which is around the £/mile for a petrol/diesel car. So yes, I hate to break it to you, if you only rapid charge, then charging station companies have priced their service so that it matches how much they’d make from combustion cars… “Surprisingly” most of them are in this £0.75-£0.79/kWh bracket… supposedly competing 😤. Gridserve and Tesla are cheaper (£0.5-£0.65/kWh).
@@CJ-gq6olbut let me reassure you, if you charge at home or even if you also fast charge (7kW) in addition to rapid charging, your cost/mile decreases to £0.07-£0.09/mile.
@@Nikoo033 brilliant thanks for the info. I don't intend on rapid charging anyway I just wanted to make sure I was on the right page with costs. I just didn't know about the % with fast charging limits. My company just got chargers installed so going to take advantage of those and charge at home over the weekend if needed.
I had a diesel engine for a 6minute 2 mile journey to work so I think electric would be great for me.
I have seen something about warming the battery up before getting in or something I'm not clued up with that if you care to explain 😅😊
@@CJ-gq6olif you rely on DC chargers then yes they're about petrol/diesel prices. There are discount schemes to reduce the price a little but the real saving comes from charging at home on a decent tariff and that can be the majority of your usage. My DC charger bill over the past year is something like £80 from a few long trips.
I had my coolant changed under warranty a couple of months ago and it has been fine ever since, touchwood.
Good to hear. This cars has it done tomorrow.
I had the coolant flushed and replaced at about 55,000 miles and the warning came back just before the end of my lease at 63,000 around 7 weeks later.
Depending on how the coolant flows through the battery internally the sensors could show the coolant is being cooled but actually there is a local blockage and a hot spot in the battery. Hopefully that is not the case. I’m hoping it is a large diameter pipe that flows coolant through a heat sink and it’s the heat sink that does most of the work bringing the heat to the pipe and out through the coolant.
Id like to see a drawing of the battery and coolant system.
Hi, I bought my Hyundai a few months ago, but recently, it's been saying that my coolant is low, although it is at its maximum. My service is due in 9 days, could you please advise me on this. Thanks.
As I had the light come on after having recall done, I was going to do a fast charge to see if I could get battery temps up then see if the warning message could be forced to come on again. Normally it's very slow charging and local roads gentle driving so battery won't get hot on my daily commutes.
Is this happening to all vehicles or just some. Have you had the sos update for the 12v battery? Or ever had the 12v battery drain?
@@CJ-gq6ol seems the coolant issue is happening to most ioniqs 38kwh and also konas. I've not had the SOS update done yet, but also not had issues with battery drain either. Cars 3 yrs old.
Hi Matt, informative video as always!! I had a query regarding this, basically my 38kwh got it's coolant replaced under the recall in September. However it's due a service in November and the dealership are quoting £600+ for service because of coolant change. I said that it's already had it done under the recall, however they said "that's a different part of the battery". Do you know if this is the case or are they just trying to fleece me?
Yes they are. But they (staff at the front desk) probably don't understand. The coolant goes around the battery and the motor stack. There is only one circuit/system and they have already changed it. So as your coolant has been changed, it doesn't need changing again. But to keep to the schedule, it must be changed again in 3 years/40,000 miles which will be out of sync with the annual service.
The dealer can't argue with this. As long as the schedules are met, things can get done early. Many dealers are still doing a repeated coolant change at the 3 year service, but they're pulling the wool over the customer's eyes. If they'd just changed the tyres, but new tyres were part of a service, they wouldn't be changing them again!
I also have my suspicions that they are doing it correctly/thoroughly too and it is a 2-3 hour job to do the flushes.
@@GoGreenAutos 👍 thanks for speedy response and keep the videos coming!
@@GoGreenAutos Its actually 4 years/ 40k miles Matt. Also worth mentioning that unlike some others that have fixed price servicing, on the Hyundai it will vary sometimes greatly from one dealership to another.
My son was told he needed the 4 year/40k service as the car was nearly 4 years old at full price (£539) and the cheeky buggers were doing the coolant recall anyways.
Its when I stepped in and said the car will be 4 years old in june 2024 and has only just turned 20k miles so please just do the 3k mile service (under £100) and the recall on the coolant!
Can you tell us the Autel device,app and OBD2 connector? So othwrs can check this level of detail. I got OBD2 dongle connector for another car but it was flaky and wouldnt work after a few uses. Do you use a paid for app?
I was using an Autel MaxiCheck MX808TS, which was £955 in 2019 when I purchased it.
Hi mat I have a Hyundai ionic 38 kw and have the coolant problem and this will be my third time and each time it’s in for full day
I have my suspicions that some dealers aren't doing the flushing properly.
I have the same car in Australia. Can you tell me the name that OBD unit that you are using ? Where can I get one ?
Car Scanner App with an OBD2 dongle do the same
I'm using a Autel MaxiCheck MX808TS scanner, which was £955 back in 2019 when I purchased it. Its not the sort of thing a DIYer is going to fork out on.
Twice a week my IONIQ FL shows the same warning.
I've been viewing a channel run by a Jaguar I-pace owner which has had a number of problems, including a requirement to top up the coolant at an early stage which made me wonder if this is an, as yet undiagnosed, issue also affecting Jaguars?
Could well be. I've heard of Mercedes EVs doing exactly the same as the Ioniq, but Merc is yet to accept there is an issue or work out the solution. I don't know the spec of the BSC-1 coolant Hyundai uses, but you can be sure that the coolant manufacturer has also sold it to other OEMs. It is a low conductivity coolant, so will be used on other EVs with wet battery cooling.
Hi Matt,
I am having this issue currently. Do you have a link for the recall for this issue? I've been searching so I can show the dealer if they try to mess me around.
Sorry I don't. Best to phone Hyundai UK Customer Services as grass the dealer! All dealers should be able to identify the coolant recall which all 38kWh cars need. There's also a SOS system recall that affects many 38kWh cars too. Both were done on my Ioniq a few weeks ago.
If you want the actual TSB number, as ask in facebook.com/groups/724470331518261 as someone there will have the info to hand.
So, just to be clear, is the original BSE 1 Coolant blue and the BSE 2 Coolant a reddish colour? Should all of the bigger battery Ionics have been recalled? I have a 22 plate and it has the blue coloured Coolant. Thanks.
Both BSC-1 and BSC-2 are the same blue colour. Yes all 38kWh Ioniqs and (2019-2022 Konas) are requiring this.
any video for ioniq ev is good to watch
I've got a few Ioniq videos stacked up to release over the coming weeks.
Most manufacturers will state that the optimum charging temperature range for the batteries is 15C to 35C, so that's probably why the coolant is not circulating to cool the batteries. It is not required.
Yes, its typically 30C. However, I've been driving the car for a while at motorway speeds, which would normally increase the battery pack temperature considerably. But the battery remained pretty cool in this case.
I see your state of charge display bars are grey, not white - same as my 2020 Ioniq. Does this mean anything?
I suspect its just my camera changing the colours slightly
Interested to know if anyone else is seeing the same 'issue' as me following the coolant flush/change. I asked the dealer for a 'top-up' bottle of BSC-2 anticipating a few air bubbles finding their way out after a bit of driving, they obliged. In the ~8 weeks since, I have had to top-up almost weekly (visually, not a warning) and used around half of the 1L bottle I was given. Have checked for leaks and there are none. Anyone else experienced this? Is this to be expected?
Oh, that's not a good sign. 0.5 ltrs is rather a lot.
No, that is not to be expected.
I’ve did 3 times recall of Refill Coolant signal. First time on May 7, second on May 15 and July 7th. And again the same day I’ve got the signal Refill Coolant?
Apparently something is more damaged in cooling system like water pump or ?
Thank you from Toronto Canada 😢
Yes, I would guess the water pump needs changing.
Hi Matt my Hyundai 38 kw had the coolant replaced and the problem is back
It seems likely some dealers aren't doing the battery flushing thoroughly enough when they do this coolant change. It's a 3 hour job but some people are getting their car back in 1-2 hours.
They will do it again under warranty though. Some people are having the water pump replaced too.
I possess an Ioniq 28 KWH Electric vehicle. While attempting to charge it using AC, the connection failed, and the car did not receive a charge. I encountered the same issue when trying CCS, and the cable appears to be in good condition. What might be causing this problem?
It could be the locking pin in the charge socket. The actuator fails and this will stop the charge process from starting. Its a common issue, but I've never experienced it myself.
thanks@@GoGreenAutos
What does hyundai service interval state when it comes to keeping the 8 year warranty?
Some cars I'm looking at 3 years old have had 2 or 3 services and the 3 services have done 40k miles and puts it over 10k miles 😅 I don't know what will be classes as full service
That’s a great question, but unfortunately most of the EV’s manufacturers out there are just guessing because they don’t know either! We used to own a 2006 Honda Civic Hybrid. It had a long California battery warranty, but Honda said it wasn’t defective until it had only 20% of it’s capacity left and that was insane! Imagine our Tesla only having a range of 30 miles! Of course it was mainly a gasoline powered car, but I had huge arguments with Honda. We got of it!
@@mitchellbarnow1709 it's super annoying as I really want one but also want that peace of mind with 8 years battery warranty. I've found one 2020 44k miles with 3 services from main dealer but at 44k miles and 3 services its actually overdue one lol I've called hyundai uk called local dealers and none have said yes its covered or no its not. Aghhhh lol
@@CJ-gq6ol Everyone’s battery warranties guarantee a certain remaining battery capacity, but then they are the ones who tell you what capacity if left. I wouldn’t worry about it too much as long as you are dealing with a good company. Our Tesla Model 3 was purchased in August of 2018 and we’ve had no major problems.
@@mitchellbarnow1709 yeah I think I'm over thinking the battery and all these videos show its reliability anyway. Its just when ypu see warranty you want it in tact lol I'd probably never need it as they don't do anything until the battery drops to 70% of its capacity and I've yet to see a video showing this issue
@@CJ-gq6ol You’ve got an excellent attitude towards them now!
Could it be a sensor issue?
No sensor, it detects the coolant issue when the circulation pump runs at a higher speed due to lack of coolant circulating. Its a pump over speed trigger.
Does this issue affect Kia’s?
I believe some Kia's have had this issue, but not in the same number as Ioniq owners. I guess any vehicle that is using the same brand/spec coolant might well have this issue. I know that some Mercedes EVs are having exactly the same issue, but Mercedes is yet to accept it or work out a solution.
Ioniq 28 is better no? 😅 You seem to have more « problems » with 38
Yes, the 28kWh doesn't have a water cooled battery, so doesn't have this coolant issue. There is now this recall on the SOS system, which the 28kWh doesn't have. But apart from that (and the Bluelink app), the cars are identical.
@@GoGreenAutos you know 28 and 38 version. Quick question: tomorrow you have to choice between two. What is your?
@@aurelienmoonf4702 I would go with the 38 for the slightly increased range, bigger screen, mood lighting etc. Its all little touches, but it just makes it feel a slightly newer car. But there's not much between them.
@@GoGreenAutosthank you very much 😊
Hi just saw your videos and they came at the right time to me thanks for this. I am seriously considering this car but want or rather need trouble free electric motoring. Would you say that this is an issue that all 38kwh Ioniqs will have at some point? I have been trying to Google the recall and can't find it. Also, what range do you get on average out of it? Thank you.
When you say there’s a Hyundai’Recall’ on this they, Hyundai UK disagree and say it’s just a “campaign “? My fluid level is below the ‘Min’ on the reservoir and was in on Friday for its 3 yr service, I mentioned the level and Campaign in the service notes but the car was returned with the same coolant level and no mention of a change. They have mentioned ordering parts for the SOS button issue and my car’s air conditioning as it has hissing sound coming from behind the right side of the dash. They said it’s got a leak and needs a part, that dealership isn’t yet aware if it’s warranty covered?? Air con still runs cold btw
No one seems to be aware of the warranty cover I've called everywhere to find out if a used car with 3 services at 44k miles will be covered and haven't had an answer.
So the sos is a genuine issue everyone is having how would you tell if this has been resolved or if its still bad?
@@CJ-gq6ol I will do. My car has set off the SOS for no reason only twice in 3 years and 33000 miles but I have a had two dead 12v battery instances and the last one I replaced it myself but added a battery monitor.
Hi there. That is odd that they didn't offer to sort out the coolant under the campaign.
I phoned Hyundai customer services to confirm my '20 plate Ioniq was covered by the campaign once I heard about it. They then put me straight though to the Mansfield Hyundai garage and I got it booked in for one month later.
It took about 6 hours from dropping off my car to collection on the day of the work. Maybe they didn't have time during your service to change the coolant also (or didn't have the coolant in stock)? It would be worth phoning Hyundai and confirming your car is covered and then booking it in.
@@Adam-ni5lt yeh, I’m sure it is, it’s a 08/2020.
@@CJ-gq6olI picked up my 2020 (October 2020) Ioniq 38 from a car supermarket in Feb this year, although it had had two services the first one was after 16 months after 20K miles and then a second at 27K. I spoke to Hyundai directly and my local dealer and they both were a bit none committal on the warranty status. My local dealer suggested I book it in for a 3rd service at 30K to get it back in line (if you aren’t in the Uk the timings may be different here it’s 10k or 12 months whichever comes first). Anyway when I spoke with the service team they said unless I had a warranty claim that would have been picked up in that first service, which is basically a visual inspection, then he felt that is the only way they would exclude the car from a warranty repair. I got the coolant service campaign done and the SOS fix done so those campaigns were carried out on Hyundais dime despite my service record discrepancy. This may be a bit dependent on who you deal with, but hopefully that may give you a bit more reassurance of what is likely to happen.
I think you have three lemons for the price of one here. 1) It Hyundai. 2) It's electric. 3) It's Hyundai and electric. Never mind, all you need now is Vodka ice to go with it, it might help a bit.
Could be worse, could be yet another BMW with yet another blown head gasket.
LTR = Low Temperature Radiator - part of the battery conditioning system as far as I can find via google
Thanks. I would guess then this is actually just the radiator at the front of the vehicle then and the LTR temperature being reported in the BMS is the water temperature as it enters the radiator (i.e. before it is cooled down) or maybe the temperature as it leaves the battery pack. On our other Ioniq when I tested it, the battery cell temps were 28-29 degC, yet the LTR temp was 42 degC.
