so after almost three years the ICCU got me

[steveinarizona]

The challenge is always to see it. I back into my garage so the car is facing away from me in the garage. But I will post back if I see it.

When I had a GV70 as a loaner, I thought I had refilled the gas tank before returning it to the level when they loaned it to me. I was advised I was a little over 1 gallon short and the dealership charged me for the difference. I think at like $6 to $7 a gallon.

At least my dealership didn't require me to refill the gas tank.

The Scottsdale dealership built a separate service facility alongside the Hyundai building. It has three bays and no other working space. I see a lot of Genesis vehicles here and I don't see how they will be able to timely service them and, eventually, how they will avoid losing sales as a result.

I think Genesis of Scottsdale decided to meet the manufacturer's requirements in the least expensive way: sell out of a high end mall and build a small service facility. My car was in the shop for almost two full weeks.

Yay. I got my GV60P back this morning. I missed my little luxurious pocket rocket.

By my calculations, it took them 2 weeks to replace your ICCU and get your car back to you.

I haven't posted about this here, but a couple of months ago the 12v failed and had to be replaced. Not the ICCU, just the 12v. It took the dealer THREE WEEKS just to replace the 12v battery! Almost a week of that was diagnoses, then 2 weeks to get the apparently very hard to get 12v battery from their supplier.

Funny. I just wrote an email to the GM raising that very point. They started on my car this morning and finished it this morning but it sat there for almost two weeks. I see a lot of Genesis vehicles here in North Scottsdale and the Service facility has only three bays and no other working areas.

If they had given me an equivalent loaner I wouldn't have minded. But the basic GV70 is no where close to my car and I sorely missed such basic features as the HUD.

Right after posting this I went out to the garage and the orange light was on! Prior to the ICCU replacement the orange light was on very often during the day/night. Maybe with the new ICCU there is better 12 volt battery management/charging and needs to recharge less often. Looking forward to your experience with the new ICCU.

That’s great they didn’t charge you for any of the gas. 2 weeks is a long time, however my dealer in Dublin, CA advised me more than once that I was very lucky they happen to have an ICCU unit in stock.

 

[steveinarizona]

I think I was right. the dealership built the service building right next to the Hyundai service area. The GM just responded that they have nine dedicated bays in the Hyundai building so I think they did just enough to satisfy Genesis corporate.

Sort of a weird decision I think as North Scottsdale is ripe territory for luxury cars and the BMW, Lexus and Mercedes dealerships have huge buildings and the Porsche dealership just replaced its facility with a 77,000 square foot building that doubled its bays. If Genesis wants to play with the big boys, it might need a more complete facility than it is presently presenting (showroom at an upscale outdoor mall, service facility as described above).

Our ICCU puked 2 weeks ago, had it towed to the dealer. Took a week to order and put in a 12v battery. Then after further diagnostic they had to order and install an ICCU, two weeks in the shop. We've had the car for 35 months at the point of failure. Tow and all repairs/parts covered under warranty.
Love this car but it is very embarrassing how much time it spends in the shop, after the 5yr warranty is up we're dumping it, 90% sure we'll go full EV again, and about 33% sure it will be another Hyundai product. My 2018 G80 sport was an awesome car too, but very problematic. Genesis needs to up their game in the reliability engineering segment. Not building a reputation for reliability in my opinion.

It interesting that several of us had our ICCU’s go out around the +/- the 3 year mark. I also don’t think it had to how many miles we had driven as I only had about 5,500 miles on my car and it’s 41 months old. I think others had over 30k miles on their cars. I understand your thoughts about getting another Genesis product. I also would have preferred a Genesis dealer in the city in which I live in. Taking any car into service that’s not too close to home is really inconvenient.

In the past ~4 weeks, five people on this forum that we know of... AZ, CA, PA, and I'm not sure the others (that's a pretty small pool). Different mileages so I assume that means widely varying numbers of charging events. I'm fascinated by the timing.

Ours has about 22,000mi on it. I wonder if this could possibly be a chicken/egg scenario? Seams that oem batteries tend to start failing around the 3-4 yr mark, what if the failing battery needing more charging over works the ICCU? Food for thought.
I believe these batteries are AGM, but wonder if they are an automotive type or a deep cycle type? I would think seeing that there isn't a need for serious cold cranking amps for starting an engine that this system would benefit from a deep cycle battery like campers use.

They didn't replace any batteries for me. They "REPLACED ICCU ASSY & FUSE" and charged the 12 volt battery which was low at 8 volts.

I have no idea what an ICCU ASSY is. Edit: I googled. It is the battery control system. Quite a complex unit.

Can you let us know if your orange light ( to charge the 12 volt battery) on the crash dash comes on. I have not seen mine come on since the new ICCU was installed last weekend.

Yesterday I was walking by my car in my home garage and noticed the yellow light on the dash was on.

Before the ICCU new install I used to walk in and out of the garage during the day and evening and see the light on multiple times. After the new ICCU install I have only seen it come on once.

 

[steveinarizona]

I have seen it in my garage at least three times in the few days I have had it back. But the front of my car is near my second refrigerator so I do go back there somewhat regularly.

Here are the insides of the ICCU for those who are interested. As you will see there are two functions of the unit. First is the OBC (on board charger) that rectifies the AC to DC and boosts it up to the battery voltage. Second is the DC to step down transformer to charge the 12v battery. During the video he makes a comment about high current AC charging as a possible cause for the failures. I don't agree that this will cause ICCU since they are in different sections and separated by a cooling channel.

Just read a Hyundai announcement (For Korea Only) that they notified all owners in Korea that the ICCU warranty has been extended from 10 yrs/100k miles to 15 years 248k miles. It will be interesting to see if Hyundai/Genesis will do the same for the North America market.

 

[steveinarizona]

If one's ICCU has failed and received a hardware replacement, does the extended warranty apply to the replacement?

 

[Acpantera]

I'm not really on board with Ed's theory of high ac current harming the ICCU in the vid. For 3 years we primarily used the free DC charging from EA and charged at home very little during that 3 years. The supply cord we use has a max of 7500kw charge rate. I just don't see that being an issue. I believe the issue is on the step down of the traction 800v battery to the 12v accessory battery.
Many here have noticed the charge indicator light on more frequently before the ICCU gave up. I think the iccu can't deal with a failing 12v battery. Now that we have a new 12v battery and a new ICCU, I think I may replace the 12v battery next year with a know quality battery.

I wonder how many E-GMP platforms won't suffer an ICCU failure in their life??
On another forum a contributor surmised that the E-GMP platform prioritised not reducing HV range over keeping the 12v battery healthy.
Perhaps a solution:
Have smart charger from AC mains when car is parked??
Bypass the ICCU 12v side with a smart charger plugged into the V2L socket, I'm not certain if the V2L can be left switched on, and keep the battery charged from that??
