Panasonic DVC Pro videotape machines from a few years ago had endless capacitor problems. The maintenance unit would have to recap every deck every couple of months.

Leaky electrolytic capacitors are why I try to avoid them where possible in my designs. Of course, there are places (like in power supplies) that you have to include them, so it's good to include redundant caps in parallel in case one fails open. They're pretty cheap, after all.

I hate electrolytic and tantalum capacitors because of their premature failure issues.
