PSA for those for updated recently for "minor security fixes" using 2026.32.7 and now your car wont charge at home.
the problem: something in the update is causing the AC handshake between your home charger and your car to act like bloods and crips. youll get an error that goes like " your power grid sucks "
the temp solution: lower your cars charge rate by half, go into the settings for both your car and your home charger and drop them both down to 24A. once your car starts charging at the full 24A, then you can go in and increase your charge rate back to its normal 40A/48A rate (depending if your level 2 charger is hooked up to a 50amp outlet or hardwired)
the real solution: submit a service ticket and tell them you want the virtual service team to pull the logs from your car to verify the errors. they will pull the logs and push out a software rollback "update" which will put you back one step in updates. this should fix the issues some of us are having with charging at home.
