Warranties are there for consumer protection. Most people know what they're there for. Even if some people didn't understand it, businesses that treat warranty as "something we legally have to do" probably don't consider the confusion about warranty a problem, because clarifying it would make more people exercise their warranty rights, and hence more costs for them.
Honestly, I don't see how any of the examples, except perhaps the software engineering one, are problems experienced by businesses that they wish to solve. Perhaps I'm greatly misunderstanding.

Edit: I think the OP may mean businesses that wish to advertise their warranty protection better explaining to users what that "end date" means, and what the warranty offers them. Which I think can be done fairly easily: look at what Apple does to advertise their warranty protection, or the warranty stickers on every fridge/washing machine you've ever bought.
Although, Apple tries to upsell AppleCare rather than advertise their legally mandated "Apple Limited Warranty" and consumer law warranties.
