In the UK (and all over the EU) as a consumer, I have strong protection if I buy a product and it was faulty when it was purchased. Even if the fault was not visible, for example if the product lasts only one year because of a faulty component.
Now with modern electronics, it often happens that the manufacturer updates the software in the product long after the product is purchased. How does that work out legally if let's say I purchased a product 18 months ago, it worked fine because it was actually faultless when I purchased it, and the manufacturer updates the software on the product and breaks it?
Normally if it breaks after 18 months I would have rights against the store where I bought. In this case the store is arguably without fault. So who has to fix this, and how do I get it fixed without going to court?
(A recent example is many Bose headphones suddenly not working anymore after a firmware update).
