> Electrolytic Capacitors are perishable, they age even when not used.

But not that perishable. I have some old electronics, along with fully analog devices (guitar effects) and they, along with their power supplies(which get hot) still work.

> People arent surprised when servicing cars, why different expectations with modern electronics?

Because they have orders of magnitude less moving parts - if any.at all. Is it unreasonable to expect something that has one moving part to not fail after two years?

Actually, I wouldn't want a car exhibiting mechanical problems after such a short period.

Old gear didnt depend on low ESR (simplified resistance at high frequencies). Every time you turn on a piece of electronic with linear power supply electrolytic caps will slowly reform and start working better and better with time. Modern gear is DC-DC converters all the way down. Aged cap means no supply voltage at all (doesnt turn on), or crazy ripple (crashes, produces funny sound or visible artifacts).

Nobody would, thats what scheduled services are for.
