As the title states. We have a new iX 50 and are running into issues with nuisance trips with the Flex Charger. The charger is plugged into a NEMA 14-50 that is connected to a 50A GFCI breaker.

Nuisance trips are not uncommon and it is typically suggested to hardwire the charger and use a standard breaker. With that said, we are renting for a few more months while we await completion of a new home. I'm debating swapping the GFCI breaker for a standard one just for the time being - in the new house, we will hard wire the charger.

Have folks encountered similar issues? Wiring is definitely OK and we had no issues with our Q5 PHEV. Maybe the BMW chargers are more sensitive. Lowering the current limit makes no difference, and the breaker is warm (to be expected), but never hot.
