That statement alone sounds good to me... If there is no repair action that can fix the range issue on these cars, then it is a waste of everyone's time to go to a service center only to have a service tech poke the battery and realise it's fine. What are you expecting them to do when you arrive? They certainly won't be taking out battery cells and putting them under an electron microscope... And measuring battery voltages and currents is already done automatically by the computer.

There is very little you will diagnose on a modern car that the onboard computer isn't already aware of.

Therefore... the idea of a team of remote diagnosis people to fix most issues without a service appointment makes perfect sense.

As does the idea of having the analysis done automatically beforehand so the human doesn't have to wait.
