I'm talking about the fees charged to a someone returning a lease for any damage, which would be less than the cost of a new battery pack. When you return a lease you are obligated for any damage/repairs not caused by normal wear & tear or covered by warranty. Tesla shouldn't charge a lease return customer for such things unnecessarily by replacing a battery pack when a repair is possible. If I return a leased Honda and the exhaust system needs to be repaired with a new muffler, they charge me for the repair, not to replace the whole exhaust system.
In this case, Tesla under-equips service centers so local battery repairs aren't possible. Shipping it back to the factory is necessary. So I can kind of understand if they charge the customer a $1200 freight fee + the cost of the repair itself, but that would still be > $10,000 less than the cost of an entire new battery pack.
Although I think it would be much better if Tesla actually enabled their service centers to do repairs like this. They can get away with it right now since they're more of a luxury/prestige brand and have minimal competition in that EV segment, but if you buy a Cadillac you don't deal with this type of thing:
As other manufacturers are catching up with offerings that compete on the lucury/prestige side of EV's as well as entry level cars. These are manufacturers with more experience in engineering their cars for decentralized service, with customers that expect that: Honda knows that their Civic customers won't buy a comparable EV if a little road debris will either cost them $10k out of pocket or raise their insurance by getting a $10k at-fault claim that raises their insurance costs. Tesla may have a hard time facing such competition without changing their model.
Currently the extra price of an EV makes attracts customers where price is not as much of an issue. As manufacturers significantly larger than Tesla enter the marker with their economies of scale and lower prices, the target customer for an EV will change, as will their expectations.
