The fact that basically all manufacturers offer the same fairly pathetic warranties (and that extended ones cost absurd amounts) should give you some idea that basically all products out there are made with similar expectations as to how long they'll last before something breaks.

This has long been the case for cars, where Japanese brands focused on reliability and were able to outcompete less reliable brands when new, and command higher prices in the used car market. Many Japanese brands are now no more reliable than their domestic counterparts, but that doesn't mean they're unreliable, and consumers are still voting with their wallets based on their past experience.

Bringing this back to home appliances, when my parents purchased their home, it came with a fancy-looking Samsung fridge, which broke shortly after the warranty period. That meant that when it came time to purchase my own fridge, I wrote off Samsung completely. Additionally, my parents purchased a nice LG washing machine, which has been running great for well over a decade now, and again when it came time to purchase my own, I went with LG. None of these were the cheapest, and I as a consumer voted with my wallet.
