The vehicle is advertised as supporting 48amp level 2 charging. After approximately one year of ownership, high amperage charging lead to overheating at the charging port, causing charging to produce errors and fail. Hyundai/Genesis released a software patch to detect overheating and throttle the amperage. This does not resolve the physical hardware that is overheating. This solution leaves the car in an unsafe operating posture where overheating could continue, leading to potentially unsafe circumstances when the vehicle is located in a garage attached to a home.

What owners say
The issue is with the level 2 charging, the car stops charging and can leave the car unusable or with limited mileage available. The charging port overheats and the car stops charging and will not restart without operator action. This is happening to many cars on this platform. Hyundia ioniq 5, kia ev6. My car has been to the dealer for service, charge port overheating code was registered. The car is being sold to charge at 48a / 240v level 2.
A defect is causing the level 2 chargers to overheat before my vehicles is charged. The chargers may overheat within 30 to 60 minutes of being in use. I must unplug and replug the home chargers in order to restart the charging process. The GV60 should be charged by 240-volt level 2 chargers at 48 amps in about seven hours, and it is not working as it stops and starts. I have reduced the charge rate from 11.2kw to 10.2kw and it still overheats and stops/starts. I reduced it all the way down to 6.8kw - the minimum setting on the vehicle. Genesis, Hyundai and Kia offered a software repair that does nothing to solve the charger problems. Dealerships perform the software modifications which allegedly lowers the level 2 charging speeds to avoid overheating down to 5.3kw which is less than the promised rate and this creates charging times of more than 10 hours. The Genesis/Hyundai/Kia Level 2 charger problems leaves all of us with different vehicles than advertised. Technical service bulletin (TSB) 23-EV-003h was issued to dealers due to level 2 charger problems when an electric vehicle, “intermittently stops charging before charging completes.” But the TSB never mentions how the software update will double the charging time. Genesis and Hyundai and Kia customers must allegedly manually turn down the charging current to prevent charge failures, but some vehicles allegedly suffer failures while charging at a low 28 amps. This means it will take much longer to fully charge the electric vehicles. I blame the problem on a defect in the charging port design which causes overheating. I would like Genesis/Hyundai/Kia to find a solution that restores the 11.2kw charging speed that I used to have on my GV60.
During at home level 2 charging, the charging port overheats
My Car Has a charging port that overheats. It consistently overheats whenever I charge it at the full speed that the vehicle is rated for, 11.5kw (48amp 240V) and their solution, was to slow my charge rate down, once the port overheats, NOT FIX THE ISSUE, it still overheats.
