because of terminology like this "Electrified Garage also notes that the cooling system doesn't get anywhere near as hot as an internal combustion engine, and it's not likely that it would either, given that the operating temperature for most lithium-ion batteries is well below 60 degrees Celsius."
So this repair is made on anecdotal observation of ideal conditions, and disregarding factory specifications, and actual Tesla trained technicians.
If this was your car, and this damaged was caused by someone else's fault, would you want a hack fix, or it fixed to the manufactures specification? He Broke Telsa's car.
>How is the risk different from the existing leased model in any industry?
Have you looked at a standard lease for cars, they dictate the terms of how their vehicles are to be maintained and repair, often hold authority of who, and how those repairs are done.
Some simply reserve the right to charge you, for services not performed by them.
Other's make even simpler, they charge you for damaging the vehicle or require you to convert the lease to a purchase, before work is done.
