It's interpretive on my side, the maintenance is supposed to be lower largely based on a lot fewer parts in an EV. But there have been a lot of real use stories pointing to higher repair costs for the EVs. Without hardcore sourcing those stories it is possible that they are shoddy slant pieces, but I think there is truth in them and it is reflected by the fact that Tesla's dominated the early EV market and the entire design of those made repairs inherently more difficult and challenging compared to other EV brands. Hence my comparing it to a smartphone. It looks great at first has all kinds of bells and whistles, but it doesn't last/ isn't readily repairable. Not claiming to be definitive just my attempt to reconcile the different info out there.
