I'd rather they guarantee a fairly inexpensive replacement. When electrics can already give you range anxiety, 70% capacity is a deal-breaker.

Batteries are getting cheaper, and I think there is a perception issue here as well as perhaps a real issue of used parts availability.

A brand new Model 3 battery pack, for example, is in the neighborhood of 10 or 11K installed. Or at least it was about a year ago, I don't closely track prices. Blow up an engine, and you won't be far off that in an ICE car. I know someone who just dropped $18K because they blew up both the engine and the transmission in a single shot. Oops.

But the ICE car has cheaper used options, for sure, where you can probably fix a 15 year old car by dropping in a reman or used engine for under five grand. Options for used Tesla battery packs definitely exist but are nowhere as plentiful. Yet!
