I have a 60A hardwired ChargePoint at home. Started at 48A but dropped it to 32A out of caution. It still charges overnight, so no big deal, and I haven’t had any issues.

That’s where I’m at. I don’t need 48A all the time, so dialing it down seems like a good idea to reduce stress on the system.

Exactly. The SC302 recall and the SC311 software update are supposed to handle charging issues, but they can’t fix hardware that’s already compromised. Even after the update, ICCU failures can still happen. I charge at 32A just to be safe, and I’ve set my car to charge to 90%, so it’s not running at full tilt all the time. It’s about reducing the stress on the system.
How can you tell if your car has the recall updates? Is there a way to check without an OBD scanner? I have a 2024 Wind with Tech Package, built in July.

Your 2024 model might already have the updates applied. You can check the Kia Access App to see if the SC302 recall appears there, or just call your dealer with your VIN to verify.
Charging at 50A can generate a lot of heat in the wires, plug, and handle. It’s much safer to dial it back to 40A or lower, which follows the 80% rule for electrical systems.
It used to work fine at 48A for me, but after the updates, it now throttles or stops. My EV9 charges at 48A from 0 to 100% with no issues, though. I wish they’d just used the EV9’s ICCU in the EV6.
I max out at 11kW with zero issues. If the car can handle 230kW DC fast charging, do you really think 11kW AC is going to cause thermal stress?

It’s not the battery that’s the issue—it’s the AC wiring at the charge port that gets stressed.
I charge at 48A because I’ve read that there’s less power loss due to resistance at higher currents. My EVSE is far from my breaker, so I figure charging at full power is the most efficient way to go.
