Scare the landlords, then walk it back and get a great deal.
This is how the conversation with the landlord would probably go:
Tesla: We're going to close our store in your mall.
Landlord: Good luck with that. Next month's rent is due in a week.
Tesla: But we're closing our store...
Landlord: You signed a multi-year lease without an early cancellation clause. I don't care if you're closing the store, you still owe me rent for the remainder of the lease. You can pay it as due or buy out your for X% of the aggregate remaining amount. [where X is some obscenely large percentage approaching 100% because the landlord has Tesla over a barrel and doesn't need to offer a discount].
Their landlords are a large number of different entities each with their own areas and laws. This is not an effective way to negotiate with 100s of malls around the country.
