Hyundai Ioniq 5

Is this the dreaded ICCU?

Went out this evening to drive to Dublin and the above popped up. Thankfully it happened on my drive so I didn't move at all. I disconnected the 12v for half an hour and reconnected but the error remained.

Just waiting on AA now but my guess is the car will have to go to the local dealer.

All updates done. Was only in being serviced in April and I was told everything was up to date now. 26k km on it and been DC charged around 20 times.

AA have arranged collection of the car for tomorrow and I had a call from Europa Car 20 minutes later to arrange a loan car. I could have had an i10 tonight or if I wait until tomorrow they'll arrange something bigger.

I'm just sending it down to the dealer to be on the safe side and make sure it's right. I don't want herself getting stuck somewhere and then it becomes a bigger issue.

I didn't check mine because I didn't have a a battery tester at home. I couldn't find my ODB dongle then either to plug in and see if that would get me a reading.

AA guy didn't check the 12v last night but the recovery truck guy today asked if I wanted to try jumping it to see if that would work as he had to do that recently on a local Garda Ioniq 5. I'm not sure if he tried or not after because I'm in work but the car is showing in the dealers now on the App.

The missus got a warning yesterday when getting into car to travel home from work, was gone before she got a pic of it and doesn't remember what warning was for. Unfortunately all power was then gone😯.

Her booster battery was flat! Fortunately a work mate jump started the car and she drove home normally. I brought her car to my local tyre place today where they had the same 12v battery in stock, which they fitted for all in price of €85. At least wont break the bank, but hopefully that's all the problem is and not the dreaded ICCU. (She has had the update done recently.)

Just to be on the safe side we have booked car in with Hyundai so they can read the faults.

I got an i10 loaner car last night off them. I have to put the key in the door to open it 😯

Dealer didn't get to look at the car until last Monday as they had a few service techs out sick. They seemed to run a long test of some sort judging by the notifications I got overnight and then the car went offline.

ICCU gone and parts were ordered on Friday but no timeline on delivery yet.

Communication with the dealer was poor and I only got one unprompted call back. I rang every other day chasing for an update and to request a loaner car.

I'm setting myself for another 3-4 weeks without the car now but at least we have something to get around in. Will be strongly considering my options when the car is back and will go look at the Polestar 2 which seems to be available at a decent price now.

My warning stayed on the car after disconnecting the 12v and leaving it sit for a half hour and then reconnecting it.

I think the Ioniq 5 is the best car we've owned and it had been very reliable up until it wasn't so that's what's making me think that trading it in might be best.

Maybe video the “stuck in gear” error with your phone, it should provide sufficient proof there is an issue. Hyundai like to avoid paying out on warranty claims unless you push hard but it won’t fix itself.

If you having are to use a booster then I would look into replacing the battery, you might be ok for the summer but once the cold weather comes that battery is very likely to fail again.

We had no battery issues for 2 years but once we had our first the second one came a month later.

One for hurling fans

Good news👍️.

Ours touch wood seems fine since the new 12v battery, but have reported to the garage. If ICCU needs doing they will only give courtesy car for two days so the quicker the part comes in the better..

It was Kilkenny who said about the two days. If the car gives trouble will give Wexford a shout. Didn't buy this one from them but bought two previously.
