2023 HYUNDAI IONIQ 6 Complaints

My Ioniq6 slowed down to 20 mph for the second time tonight. No matter how hard I pressed on the accelerator the car would not speed up past 20 mph. A message on the dashboard said “Limit: 20 mph”. Eventually the car picked up speed then said “Limit: 43 mph”. (The speed limit on University Blvd at this point was 35 mph). I did not test that, as I was almost home. This happened around 7pm on Saturday, Nov 18, 2023. My wife was in the car with me and asked why I was driving so slowly. The first time this happened, a couple weeks ago, I don’t recall seeing a message on the dashboard. I fiddled with some of the controls on the steering wheel and it sped up. So I thought I had fixed it.

I have a 2023 Ioniq 5 that was purchased in June, 2023 and an 2023 Ioniq 6 that was purchased in April, 2023. I had a new Chargepoint Home Flex charger installed in April when I purchased my Ioniq 6 and set the charging current to 40 amps. The charger was hardwired directly to my service panel with the appropriate 6 gauge wire and 60 amp breaker. My Ioniq 6 reliably charged at 40 amps until early July when it started dropping the charge rate to 23 amps about 40 minutes into my charging session when using the level 2 charger at home. My Ioniq 5 only charged at 40 amps for the first week of ownership before starting to drop the charge rate to 23 amps. When this behavior started I plugged an OBD2 scanner in and was able to monitor the AC Charging Inlet temperature and noticed that the charge drop happened when the temperature reached 240F. This causes an issue when planning my charge times because they can essentially double, meaning that my vehicles are not ready for a trip by the estimated time. I am also concerned that having electronics that overheat on an EV may be a potential fire hazard in the future. One of the key reasons for purchasing these vehicles was the advertised charge times. I have appointments with the dealership to have both of these vehicles diagnosed.

Car's onboard AC charger overheats, I can replicate every time upon charging Poses fire hazard Dealer will not confirm, but TSB's have been issued to reduce the charging current (car no longer charges as advertised at time of purchase) Inspection performed by Ioniq certified dealer Warning first appeared June 2, 2023

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
