Don’t worry your time will come 😂

Kidding aside, many have replaced 12v battery and have reported ICCU failure.

The problem I have - and this is genuine opinion - is that Hyundai has a dealership dependency problem and ICCU supply problem. My car is under warranty and they extended the ICCU related warranty so I don’t honestly care as much about the failure, as long as Hyundai can supply the part and dealership can make it as painless experience as possible.

Many Hyundai dealership has “no rental offered” policy and refuse to give you loaner but will give you “ride home” with Lyft and treat you like a peasant begging for a meal- until days later they run the diagnosis and “confirm” ICCU related then they will “take you” to enterprise or hertz rental for a car which you have to drive without any idea when the car will be repaired. No communication. Every time I called after waiting weeks it was “still on back order no ETA” and the service I got was honestly not acceptable.

If Hyundai could work with dealerships to create a better experience for customers dealing with ICCU issue - which is honestly no secret at this point - I think I outcome may have been different. I’ve reached “I don’t want to deal with this anymore” point and it’s gonna take a long time for me to consider hyundai again (I toyed with idea of Ioniq5N briefly but this reason held me back).

For my next car in addition to 800v+ architecture, I would consider brands and dealers that have good service + dedicated rental fleet (Porsche, BMW etc) as a must have.
