Hyundai INSTER

No vouchers from my dealer and service was expected to be every year, although mine isn't due for another 6 months.

Thanks both, dealer came back yesterday evening to confirm it was the health check and is free. That's a handy link to have.

Well Folks, looks like I could possibly be the first to report a second ICCU failure.

Will keep you updated over next few days.

How many kms on the car do you have now?

6500km on it. Very light use.

Fast charge completed ok. Running for about an hour. The failure over night appears to have happened after 1.5 hours.

Looking at the Zappi data it actually dropped from 7.2Kwh to 1.1kwh which is odd.

I am hoping this was some kind of Zappi firmware issue. We will see.

No guess about it - well reported on here that Hyundai/KIA don't have a fix for the ICCU issue and the replacements they send out are just as likely to fail, because nothing has been fixed in the component design.

You are rolling the dice to a degree if buying a Korean EV.

And for anyone thinking of returning a car to Hyundai - good luck 😅 They're up there with Nissan.

Still looks like an ICCU failure but a few more things to try.

Good point, the challenge has been letting charging run long enough to fail and then having to run the charge down again. Takes time.

are these cars sketchy enough, poor reliability?

Yes, Inster.

The wall charger failure was initially ignored essentially, which was very disappointing. I pushed it to outline the seriousness of my situation and was eventually told by the dealer (and later Hyundai Ireland) that I'd need to provide a report from a competent person (e.g. electrical engineer's report) to back up what I'd self reported and confirmed with the facilities manager at my workplace responsible for the chargers, if I wanted them to follow up. Given that it wasn't my charger, I wasn't able to get this directly myself (and I'm not sure I'd have liked setting the precedent that I should do this on my dime where I feel this could be a safety issue!), and haven't chased it further as work has already replaced the charger with a new one.

Pretty much a no, correct. I'm glossing over some details where I was given incorrect information about what was repaired (like where I was told it was ICCU, then just ICCU fuse, before I pushed for them to correct the record and it turned out to be both), but in summary a small extract from after a few weeks and pushing for a yes/no answer on refund:

"I have not followed up on anything regarding the charger that you mention below, but I will need some kind of report as to the extent of the damage from a competent person as these units are very well protected, like ours are here in the workshop. They don’t just blow and then be rendered useless.

I have had a chat with <Dealer Principal> and he is of the same opinion as myself, that we are entitled to try and repair your vehicle, which we are in the process of doing, and, at this moment, we will not be in a position to take the car back.

Of course, if this happens again, well then that is a different scenario but as far as we are concerned here, your car has been repaired correctly, and once this 3-way valve has been replaced and rigorously road tested, we are happy that the car is good to be returned to yourself."

The "third time would be different " is just .. meh. Consumer law makes no such distinction (in summary of https://www.ccpc.ie/consumers/shopping/buying-goods/refunds-for-goods/ ). Serious faults are grounds for a refund. Additionally, recurrence of a fault despite previous attempt to repair is also grounds to refund (this is subject to several conditions for some situations where trader can make the customer accept further repair attempts, like whether customer can have confidence in the repair, fault is not serious, the value of the goods etc.. I argued this and other points in much more detail to no avail. Unfortunately, the law is only as strong as its enforcement.

Specifically, my understanding of CRA 2022 (I'm not a solicitor, this is not legal advice, blah blah blah):you can terminate a sales contract if

Consumer Rights Act 2022 Sec 26 https://www.irishstatutebook.ie/eli/2022/act/37/section/26/enacted/en/html

(1)(b) the same or a different lack of conformity of the goods with the sales contract becomes apparent despite the trader having attempted to bring the goods into conformity with the sales contract,

(Subject to Sec 26 (5,6))

This grants the right to a full refund (in theory they are only able to deduct for depreciation in excess of normal use!) under Sec 28 https://www.irishstatutebook.ie/eli/2022/act/37/section/28/enacted/en/html#sec28

No, it was in for the coolant valve issue in November I think and they said it was drivable while the part was on the way. The part was on order until late December. They ended up replacing the ICCU, ICCU fuse, and then separately the coolant valve after a couple of weeks later - all in December.

The first ICCU replacement was in April.

Changing the charging RATE (AC charging current menu) to 90% is a workaround for this issue in that it allows the car to be charged at a consistent rate of about 6.2Kw. I've been using this for the last few months while waiting for the promised (mythical?) "software fix".

The actual charge capacity can be set to whatever % you want.

Is this limiting to 90% charge rate an option as a preventative measure to the ICCU failing? I'd be 'happy' to do this if it meant avoiding the hassle of getting the ICCU replaced.

Hi Folks, doing some research here.

For folks who have experienced ICCU failures, can you tell me if you have a 1 Phase or 3 Phase home charger and the make? Thanks.

I would assume that nearly all home chargers are single phase? Most homes would only have a single phase supply!
