NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2023 Hyundai Ioniq 6. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
The Ioniq 6 is supposed to be able to charge at 48 amps. I bought a new Ioniq 6 in early June 2023. June 12 I had the level 2 Juice Box 48 amp charger installed. At least twice (I think three times), it would stop charging after about twenty minutes — the charge port appears to be overheating in certain situations. Please have Hyundai either fix the port (or other hardware) and/or software. They may not advertise 48 amp charging when so many users are having overheating problems. They need to own this and be accountable. Precisely this happened on the Ioniq 6 to me: https://youtu.be/uXi33MtrJAU
