2022 Ioniq 5 Limited AWD, Phantom black, black interior
My wife had a brilliant idea to try and charge her Tesla 3 with the V2L feature. I bought an OEM V2L adapter from S Korea on eBay and an outlet adapter on Amazon per advice on another thread. We used the Tesla supplied cord that we normally use to charge the 3. But as soon as we fired it all up, a red light appeared on the 3 next to the charging port, and the interior screen said there was inadequate outlet grounding. The 5's screen said it was transferring V2L. Any idea which of the many components was failing?
