I don't think it's actually what you meant to ask (I think you are actually interested in legally mandated warranties rather than the courts where they're enforced) but I think most countries have something equivalent to "small claims court" to make low-stakes suits viable.
I have successfully used exactly the same technique of "get a court date, wait for your opponent to contact you and resolve the issue, cancel the court date" in the past to challenge an illegal rent increase in Switzerland. The court for that here is called the Schlichtungsbehörde.
It seems like we have 2 year legally enforced warranty (which I knew about), and some sort of small claims court (which I did not know about).
I think I would have heard about legally mandated warranties that extended beyond the 2 years I knew about. The Australian system seems quite reasonable, I wonder why we don't have something like that? 2 years for everything seems pretty weird.
