I looked at those as well, but the ICCU issues were enough to deter me. I do a fair amount of highway driving and the thought of suddenly dropping from highway speeds to 12 MPH was somewhat chilling.
Maybe they are not as common as it seems.
- coldpie 2y agoI think that's solved by a recall, so if the car you're looking at is either new or has already had the 12V battery serviced, it should not be an issue.
- verdverm 2y agoI just dropped mine off for recall, it's not a big issue and if you don't own one yet, it will already be fixed.
- fullstop 2y agoWhen I looked into it, people who had the recall performed had it happen again. This made me suspect that they were trying to correct a hardware problem with software, or that the software was somehow able to damage the hardware if it wasn't updated in time. That was on the EV6, though, but they share the same eGMP platform.
- verdverm 2y agoThe recall has gone through multiple stages and expansions. At this point they are replacing the ICCU fullstop 1. Software fix 2. Replace fuse 3. Replace the ICCU and be done with it
- fullstop 2y agoRegarding #3, are they actually available now? At one point they were seemingly made of unobtanium.
- verdverm 2y agoApparently it depends on dealership / market. Mine's in today, Reddit has reports of people being told as late as March. Hyundai Finance is working with customers who cannot get the fix in the near term
- r00fus 2y agoAs an owner of a used EV6, I can tell you this issue has caused some concern and I do think it's a real but rare issue. However, my calculation is this: It's a 1% impacted issue. Replacing with an AGM battery drastically reduces the issues. Recalls somewhat mitigate this issue further. Apparently reducing your L2 charging rate to < 7kW also reduces this. At the end if you are still unlucky, the ICCU is almost always covered by warranty but replacement is annoying and can take months. To mitigate I plan to replace my stock 12V with AGM, and buy a portable battery starter.
- fullstop 2y agoI ended up with an Equinox EV instead. I suppose that it's the devil you know vs the devil you don't, as the Ultium platform is still pretty new.
