I'd like to see it extended to most consumer goods too, obvious exceptions for consumables and physical damage but TV's, appliances, phones etc should be warrantied for 5 years minimum.
You can often make a valid legal argument that if the manufacturer or retailer is offering an extended warranty option for extra cost. Then it's reasonable to expect that type of product should last that long.
So if your local consumer laws state that a product must last for a reasonable length of time then by them offering an option of an extended warranty they have proved what "a reasonable length of time" is and so everyone gets that length warranty for that device under the law.
Of course you have to argue it and the reseller might force you to go to small claims court to win.
But that is usually pretty cheap, being small claims court. Depending on where you live.
More of a time cost than a money cost.
This is why extended warranty are often a scam.
