NHTSA Complaint #11506567 — 2022 KIA EV6

The on-board charge controller on my EV is drawing excessive current from my Level 2 EVSE portable charger. When my charger is set to 24 amps maximum the car will draw 28 to 30 amps, causing the charger to shutdown and report a short-circuit has been detected. When my charger is set to 40 amps, about an hour into charging the car will draw 46.6 amps again causing the charger to shut down and indicate a short-circuit. My understanding of the Level 2 charging standard is that the charger tells the vehicle its current setting and the vehicle is not supposed to draw more current than the charger tells it. I've done lots of reading online and this is a problem EV6 and Ioniq 5 owners are having with a variety of charger brands and some owners state that the same charger when used with other vehicles like the Mustang Mach E does NOT draw more current than the charger is set to. It seems to me like this is a HUGE safety issue, as excessive current draw is causing the charge cable to get hot and could cause a fire. Kia hasn't indicated any willingness to fix the problem and they don't seem to be treating it with the seriousness it deserves. I took my car to the dealer and they grudgingly applied the only Level 2 software update they had, but it has not made any difference in the problem. Now they say there is nothing else they can do.
