Hi all, I have a 2023 Kona EV SEL, 100,200 miles. Dealers performed the 9C5 recall update for me last week and it shows the “ check electric vehicle system” warning light is on. I called the dealer and they say I can tow the car to the dealer at my own cost and they will performed an inspection with $300 fee. If it is related to the recall, they won’t charge the inspection fee then. Have you seen the similar warning before after the update, any suggestions for the next step? Really appreciate it!

If the car drives there's no reason to have it towed. I'd email them a photo of the warning light and ask if it's "safe to drive". If it's not drivable call Hyundai Assistance or whatever it's called wherever you live and have them deal with it.
The update you have is likely been around the RoW since Jan 2026 (as it has a very similar description) and a few recipients have had this happen. Generally the fix is a new traction battery.

Thanks for your reply!! It is still drivable and the dealer who performed the recall update is 30-min away while I have another dealer is nearby about 5-min. Should I go to the one who performed the recall update.
One thing I’m concerned is that my car just passed 100k mile, which means it is out of warranty. Not sure if I need to pay everything out-of-pocket or it is related to the recall issued so Hyundai will cover it.
I am also interested that should I do something g simple to check by myself first. Like 12-v battery issue? Or something else. I bought this as used car about 6 months ago before and first time to see this warning light on. Appreciate it!

I'm not aware if your battery warranty is still in play but the campaign document addresses that situation. I'd use the dealer that did the update since they may feel more obliged to help since they did the work and should warranty that.
The error you're seeing covers a number of faults but the timing with having the update does seem to indicate that was the cause. The update tightened the tolerances of battery cell voltage variations ("balance") and temperature.

Really appreciated it! Is
is there a way to tell if the replacement is subject to this recall update or not? In case the dealer is misleading me. Thanks!
I went to the dealer today and he kept saying that everything is due to that I don’t do the service. The vehicle is giving a message that vehicle is due for the service. I bought this car from this dealer 8 month ago and have driven 6,000 mile since then. He said the electric car also needs fluid update which is similar to oil change for an oil car? Because of that I don’t do the service, it damages the battery. Is he right? Or he is just using this to try to put all the cause to me while not the upgrade or the car itself?

I've not heard of any 1st-gen Kona owner reporting that the battery had been damaged from lack of carrying out periodic maintenance servicing. The coolant replacement interval is at 40k (or possibly 35k) miles for that year and your's was not subject to the BSC1 coolant campaign which resulted in lots of related problems for those earlier examples. There's been no indications that leaving BSC2 coolant change intervals longer has been harmful.
You said you had a “check electric vehicle system” warning light which is not the same as a "service due indicator". The prior indicates and electrical problem and that needs to be diagnosed and rectified, not a difficult job for a trained Hyundai technician. But given that the update reduces the tolerance for battery parameters and a few others have seen this as well, it seems likely that it triggered the warning.
I'd suggest asking the dealer to "get your car in working order please" which long ago was what dealers did for a living.
