The OP brings up an interesting contradiction: appliances have become less reliable but cars have become more reliable. Cars have become worse in some of the same areas as appliances, like the use of touch screens instead of physical controls, but cars have nevertheless become more mechanically reliable. What would explain this opposite trend?
The reliability of cars, on the other hand, used to be pretty awful. Lots of maintenance, regularly needing repair work done - not to mention regular servicing, oil changes and tyre changes. And people replacing their 5-year-old cars because 'old cars just aren't reliable'. So there was a lot of scope for improvement.
That stove top broke after a couple months, but luckily we're in Denmark where the warranty is a year, and when something gets repaired like that it's also under warranty for a year (actually sometimes more). We got that stove top replaced about every 4-6 months for 4 years until finally they did a good enough job that it lasted. The repairman said yeah sometimes it's just like that, ha ha.
No monetary cost but every few months you can't cook for a week.
Luckily I also bought a portable non-induction stove with two plates which we use whenever the main stove has problems.
You may or may not be a fan of the Euro, but EU law is two year warranty for consumers.
So far that has worked decently well : my kitchen water heater (3 year warranty) is going on nearly a decade and only now is starting to have issues, while the previous one, albeit significantly cheaper (minimum warranty), only lasted half a year.
(One should not underestimate the cost / effort spent dealing with a poorly working / broken tool.)
Ford's EcoBoost and Peugeot's Puretech engines come to mind in particular, with the latter being so bad, that they tend to fail well before 100k km, and there's an active investigation going on about it by European Commission.
