Everything I’ve read is they cost much more to repair and many are being totaled because the insurance companies don’t want the liability if the battery pack is damaged and catches fire later.
A lot of used EV’s in my area are Insurance Loss and Lemon Law vehicles lol. The battery is easily the most expensive component to repair. If the insurance costs have lowered them its likely because manufacturers are just eating some repair costs for them. The components haven’t gotten much cheaper.
My EV6 GT caused my insurance premium to decrease compared to the VW Tiguan it replaced, but I think that’s because Progressive lumps all of the EV6 trims together. I’d imagine it depends on the provider.
I was thinking the I-Pace was expensive to insure compared to my old ID.4, but then I recalled it was an 85K vehicle new (vs. 40K) sold in small numbers so it kind of checks out.
I would imagine TM3/Y aren’t terrible anymore to fix except maybe the simplified, half shell cast versions.
