    Unknown Error BMS_a066

    I hope you get a HV battery soon, they have had my car since the 24th March and still haven't gotten a HV battery assigned. From the sound of the text I got from them today I don't think I'm getting mine back anytime this month.

    Two new errors this morning bms_a064 & bms_a174 and the car failed to charge last night. Service Appointment is tomorrow, luckily I think I have enough charge to get me there.

    Just had the error (bms_a066) pop up on Saturday, appointment scheduled for this week (although the fault disappeared on my way in to work this morning). Any info on what is actually wrong with the battery / management system? 2021 Model 3 Performance (4500 miles)
