I don't think the rework rate is a big deal for the customer. Ultimately manufacturing is about increasing the yield rate so that costs are lowered, because rework is expensive. But if you can make money with lots of manual rework on every product, it's no big deal. Something to improve next quarter.

I have so many electronic devices, from cheap to expensive, that have some passive component manually bodged on somewhere. They work fine. It just means that paying someone to rework 1000 boards was cheaper than throwing the boards away and spinning up Revision B immediately. It's not a big deal. Waste is worse than a product that is imperfect immediately off the assembly line.

Rework dramatically slows production.

Tesla cannot get the rest of their booked-sale cash for an undelivered car.

But they must pay all the fixed production costs anyway. In cash, creditors at this point will be getting squirrelly.

Therefore: slowness in production is the fast-track to a possibly fatal cash crunch.

People are waiting 3 or 4 months for replacement parts for their vehicles or Tesla has had possession of the vehicle (and the person is using a loner) for a similar amount of time. That won't fly in the mass market.

Is Tesla making money?

It's not about money. Correcting and refacturing a board takes time, in the order of months even for a simple one. It's too long.
