I didn't say it would look pretty or be safe ;-) But I have no doubt that something like heated seats could be hard-hacked, I mean there are a lot more complicated pieces of equipment out there that get hacked. Personally, I wouldn't cut holes in the seats of my brand new $50k Audi, but some else might.

You'll find you are NOT covered if you make changes or modification and in soem countries you are not ALLOWED to make some types of modifications.
I agree, there is a contract but it typically expires when the warranty period runs out.

Patents and copyrights as the name suggest is to prevent copy and redistribution. It doesn't prevent me from reverse engineering anything I bought. I know there are gray areas to this, but for genuine personal use I am free to do a lot.

There is no law that says I can't look at the code inside the ECU. It just depends on what I do with that code. As well, if I go around modifying things with unintended consequence I may be legally liable. But isn't that price of freedom?

IANAL so feel free to correct me where I am wrong.

That is an interesting point.

If it says you did not purchase the heating element and control then you do NOT have a right to use. Just because something is "ther" does NOT imply amy right to use and in the case they woudl offer a pay-as-you-go model then the contract will make that clear.
I just don't ever see how this can be legal. I buy a car without the heated seat option, but the seat heating system is still installed. I decide to build a street racer and therefore part-out the factor equipment starting with the seats. Someone with a heated seat enabled car buys my seats, because their seats broke and they don't want to pay OEM prices.

If I don't own the heating system I would be breaking the law by selling something I don't own.

I wasn't clear before...I am talking about personal use only. You are talking about copyright, resell, redistribution, etc but I am talking about what I can do in my own garage for my own personal use.
