The repair tech made some comment about there being a lot of safety protocols to work around the battery....
Electricity from the HV battery can be disabled by pressing and holding the Power button for a grand total of 3 seconds. Let’s pray that the tech is aware of this nifty feature. Additionally, they will be dealing with the end of the operation that provides 120/240V FROM a wall outlet or charging station TO the charger. Let’s pray that the tech won’t have the car plugged in to a charger while making this repair.
It would have been a much more credible explanation if the tech had said we need to do this, that and the other thing, then put it all back together, and it takes 4 hours.
