> The context here is not "they're half-assing it because the system demand are minimal so they can". It's "this repair technique works just fine on real automotive cooling systems that are much more demanding".
Firstly, using a tap to reverse thread into plastic housing, and then using brass threading into the housing and into a cut hose with a screw clamps.
Internal combustion or not, its hackish, the article even recognizes that, and their defense is that some people in Tesla's factory shipped some cars with fake bits of wood from home depot. You don't put metal threads into plastic in something that is exposed to vibration, in this fix they do it 4 times, it might work, for a while, but it isn't a good long term solution.
It's not a hypothetical, it happens literally every single day, I spend my youth working in a car shop, and people expect their cars to be fixed the way they where made, and even more so when someone else damaged it, and they (or their insurance company) are financially responsible.
It would be foolish for Tesla to allow this, they will likely want to sell that car after the fact, and I doubt they want to take on the liability of selling that car, that had this sort of hackish work done to it.
Also, I don't know where you reference for "Most people's answer is going to be..." but it wasn't my experience when working in a shop, so on that we can agree to disagree.
At the end of the day, he signed a lease, and agreed to the terms, those terms include how this maintenance and repair should be handled. Right to repair isn't going to change those terms, even more so when he isn't the owner of the vehicle.
If anything we should take away, is that leasing cars is stupid, on many levels, and this just high lights another one.
