No. Newer versions of Tesla's software disable the radar on cars that shipped with it.[1] Vision has gotten so much better (thanks in part to training from radar data) that radar adds noise to their model of the outside world. Andrej Karpathy explained the issues in a talk this summer.[2]

But you get the car. Some manufacturers have simply shut down production while they wait for parts to become available.

But at some point it stops being the car that I ordered as they strip parts from it. Arguably it stops being the car that I ordered the moment they decide to start taking stuff out of it.

You're buying the final product, not specific components when you place your order. As long as it functions as advertised and meets warranty requirements, it is what you were sold.

At least in the case of my Model Y, I was given the option to decline my order as it was placed before the vision transition [1], so there is disclosure and the ability to opt out.
