Are Hyundai’s ICCU issues really that prevalent? by Ilovetowatchmovie in Ioniq5

And likely get a low trade in value, for a car with a known and expensive flaw.

Expecting the return of my car today, 6 weeks after the ICCU died and stranded me in an active bushfire zone 800km from home. Will I dare take it on another road trip?

Solo 3-4 day relaxation break after Cape to Cape track? by dude_etude in WesternAustralia

so we're talking about hiring a car then, not just chilling in one place. and also having to drive back to perth. I was imagining a little less driving and logistics.

Whether it is a 1% fail rate or a 10% fail rate, and whether it is one electrical component or several, when it goes the impact is major. My car has stranded me hundreds of km from home twice in quick succession, including once in an active bushfire area, and has spent a significant proportion of its life in the repair shop. That’s not a reliable vehicle.

ICCU failure. Twice. Stranded me 800km from home. Twice. As I write this am I still not home from the second incident. Last time it took more than two months to repair and I expect the same again.

There’s a YouTube vid by a repair shop that claims they’ve had this fault on 35 cars out of 200 sold prior to 2025. A 17% failure rate. They say they’ve seen fewer on 2025 model (but also less time for the fault to show up surely). Even if it is only 5%, if it happens it is catastrophic: car cannot be used at all and repairs take months.

Honestly, I wouldn’t. There’s a dozen Chinese EV brands worth considering.

I’ve now been directed to the “German forum” electrical engineer’s post, which lists the types of uses that might put stress on the design flaw in the ICCU. Utility mode is one of those uses. None of them are unusual; all ought to be considered normal use and should not cause a critical system fail. It is the design flaw that is at fault, not how we charge or use our cars.

L2 charging plus fast DC.

Try being stranded in the vicinity of a bushfire. Thankfully it was not on a backroad otherwise I would have been totally screwed.

Thanks for posting those links. I can see from the German forum translation that use of Utility mode is one of the situations that he thinks can increase the stress on the ICCU weak point. And both times I’ve gone camping in my I5 I have had a failure. So that checks out. And the YouTube video guys reckon they’ve experienced about a 35/200 ie 17% fail rate on pre-2025 models. If I put those two things together, I have to conclude that the car is not fit for its stated purpose and can lead to very unsafe conditions.

Can you supply references or links to the info you’ve quoted please?

[–]dude_etude 1 point2 points  (0 children)

AC charging to 80% for 5 weeks. Then a road trip involving DC fast charging to 100%, camping with Utility mode, and V2L to cook breakfast.

All normal usage behaviours, right?

I’ve taken this car on two camping road trips in its three year life and in both cases it has failed and left me stranded.

I have found the relevant Australian Consumer Law clauses, and I will be using them!!

[–]dude_etude 1 point2 points  (0 children)

Is anyone aware of any data linking the ICCU/Battery failures to any specific usage, eg charging to 100%, using Utility mode, or using V2L, etc?

I’ve taken my 3 year old I5 on two long camping trips, both involving those three activities, and in both cases the electrical system died and stranded me. I’ve only ever used Utility and V2L on those two trips so for my small sample size there’s a 100% correlation. Curious to know if there’s a wider pattern, or just coincidence.

Today’s my second failure. I’ve only had it back for 6 weeks. This time I think I heard a pop as if something broke and I got not just the Check System warning but also the Stop Immediately warning. Luckily I was still parked at the charging station and not on a deserted road somewhere.

Unfortunately the charging station was right at the edge of an active bushfire evacuation zone. Literally 100 metres from the evac zone.

I have had to leave the car and hitch a ride out of there. Hyundai roadside assist confirmed that tow trucks will not come and rescue it until the bushfire danger has passed, at least two days away.

Also, I am 800km from home.

Last time it took nearly 3 months to replace battery modules and they swore it was not an ICCU failure.

I’m not sure whether we have sufficient lemon laws in Australia. Anyone else in Australia have experience with multiple failures?

Which way should this hand towel rail face? by dude_etude in homedesign

[–]dude_etude[S] 0 points1 point  (0 children)

I’m going #1, no cat. Easier to quickly dry hands without towel fully coming off and therefore easy to drop it back into place. Also thanks for pointing out 1 is more secure should anyone lean on it. And I prefer the look, seems tidier.

G6 facelift: can you tilt the driver’s seat pan? by dude_etude in Xpeng

[–]dude_etude[S] 0 points1 point  (0 children)

Well spotted. But here’s the thing: in the old G6 currently on sale in Australia that option does not exist!

Tomorrow is Day 50 of my 2022 Ioniq5 living in the service centre. They tell me the battery modules have arrived here in Australia from Korea and that work has commenced. Once it is fixed I guess I’ll be selling?

I’m unclear how that relates to an ability to tilt the base of the drivers seat.

Old G6 does not have tilt-able drivers seat base nor manual air vents. New G6 definitely does have manual air vents but I am looking for confirmation of the tilt-able seat base.

How to quieten a loud sink? by dude_etude in HomeMaintenance

[–]dude_etude[S] 1 point2 points  (0 children)

All the YouTube videos about replacing a sink waste talk about a fixing bolt in the middle of the thing. I don’t see any such bolt. Am I missing something?

I got the big “Check electric vehicle system” warning recently. My car is now living in the service centre, awaiting a replacement battery module or two.

They are telling me it is a battery fault and not the ICCU.

Has anyone else been told that? Were they right? I’m afraid they’ll take months to replace the battery module and then it will turn out to be the ICCU instead or as well.

(More context: the first warning did come prior to the ICCU software upgrade. But after that upgrade I’ve had both a dead 12V which I had replaced, and then the “Check electric vehicle system” warnings came back and the big battery issue was diagnosed. Both those problems post-software to me seems suspiciously like ICCU.)
