Home charging not working
Leased a 2026 iX 60 last week, previously a service loaner. I have a wallbox L2 charger connected via Nema 14-50 outlet in a 50Amp breaker. Bmw software updated to the latest version
1st day Car set at 48A limit and Wallbox at 40A limit. Charges at 7.3kwh from around 20-55%
Next day it stops after an hour or so and trips the breaker.
After that it isn't charging at all.
My diagnosis -
Tried reducing the power to 32A/16A - no luck. Just getting a blinking red light with 'Grid power too low' error.
Next tried with the onboard charger connected to the Nema outlet - Same error.
Then tried with level 1 120v outlet - Same error
Took the car to a nearby EvGO charger to try DC fast charging. Same error
Next day I took the car to a nearby dealership and dropped off. They have the chargepoint fast charging and everything works normally in it and they just return the car saying no other issues.
Now I tried again at home with 32A and no luck.
I called the electrician to check the ground/neutral and confirmed 240v in the outlet and everything looks good. He has a Ford F150 EV and wallbox charges it without any issues.
I heard about CCU issues in EX90. Is this a common issue in IX too ? Could this be related to the most recent software update ?
I'm suspecting that the dealer did not diagnose the issue fully and returned the car.
Looking for guidance.
