NHTSA Complaint #11702654 — 2022 HYUNDAI IONIQ 5

I have had all recall updates on the car including a recent one on 10/13/2025. Turned on the heater on the first cold night in Dallas this fall and got the engine warning light. Checked the ODB and code was P1A90(96). I was able to drive it to the dealer with a 40 mph max speed. The funny thing is my ICCU has already been replaced under warranty once like 16 months ago, so it seems the replacement parts aren't much better than the original. Dealer confirmed it is an ICCU failure and I'm now waiting on the part. Hyundai has NOT fixed this ICCU problem even when they replace with a new ICCU. Someone needs to hold them accountable for finding a real fix.
