It was a Japanese problem in the 1990s. This type of capacitor was much
smaller than previous types, so it was an obvious choice to use them
everywhere. There was a surveillance camera that used over 100 of them.

The problem was that they had various temperature ratings. Most had a
life of 1000 or 2000 hours at their maximum temperature, which isn't
very long when run continuously. This life roughly doubled for a 10
degree decrease in temperature. So when they ran cool, or in
intermittently-used equipment, they were no trouble. But eighty degree
capacitors running at fifty degrees might last around 10000 hours,
which is about a year in continuous use.

The unfortunate thing was that this type of capacitor failed in a way
that previous types did not: it leaked electrolyte. This reduced the
capacity and eventually caused many faults, which were worse when the
equipment was cold. And the electrolyte dissolved copper, so a leaking
capacitor would destroy the printed circuit tracks nearby...
