ICCU recall / 12v battery effectiveness

[nwwoods]

Has anyone encountered the dead-12v-battery problem after having gotten the ICCU recall (+ software update) completed? Did the recall fully address the concern? Researching this issue, it's difficult to tell.

Per NHTSA, the recall (initially) covered 23-24 but 25 was apparently added as it's in the recall also. It also affects Ioniq 5 and EV6 as you might expect, and those forums have owner experiences as well. Per anecdotes here, it seems relatively infrequent to run into the problem. Also per anecdotes, it's unclear whether you've encountered the problem after having gotten the recall work done. Can you shed some light?

My wife is looking at a 2025 GV60 buyback vehicle that was bought back due to "battery concern" per the paperwork. It's up to date on recalls except the windshield molding. The dealer is mum on the details of the buyback, and we certainly don't want a vehicle that will leave us on the side of the road, so we'd like to understand, did the recall fix *really* fix it?

Thanks for any insight.

I have a 2024 Advanced. Never experienced 12 battery issues before or after the software update.

Same.

Around the beginning of the year I installed a bluetooth battery monitor on the 12v battery, just out of concern for the reports I'd read. So far in 8 months it has never shown any problems.

No issues with my 2024 Advanced.

No issues either but if I were you, I would strongly urge you to avoid the buyback vehicle, especially considering you don't know what it was bought back for.

Clearly, whatever it was - Genesis couldn't fix it to the original owners satisfaction after multiple attempts, and whatever it is, it may not reveal itself on a short test drive. Or if they purportedly fixed it, it may happen again.

Personally, I wouldn't want to have that as an added thing to worry about across the ownership experience.

There is a sufficiency of testimony on this and other eGMP-vehicle owner sites to fairly conclude that "the fix" is not "the fix", as even new, and relatively new, vehicles succumb to the ICCU failure and/or 12V battery failures (less than 1500 miles on a '25 in a fresh story). Perhaps the failure rate has declined, or is declining. The best news on the topic is that the replacement of ICCUs now seems to be taking less time...days, rather than weeks or longer...but it's same ICCU...warranties, but no guarantees.

I have competed all of the ICCU warranty work and have not had any issues before or after the repairs. I still carry a jump starter in the car just in case.

Same for my 2023 performance. No problems but keep a jump pack in the frunk and the mechanical emergency key, always accessible from outside.

Actually, the dealership is required to show you the document with buyback details when you ask. I did it when I purchased mine. Fortunately, it wasn't for the ICCU error, so I purchased it right away. I've had no issues so far
