It could have been as simple as that. My company has been bitten by bad batches of capacitors in the past. We are now very picky about our sources.

Traditionally electrolytic capacitors tend to have a more limited lifespan compared to other electronic parts, primarily because of their "wet" electrolytic dielectric material and construction.

The worst example of bad capacitors I have heard of involved electrolytic capacitors produced by certain Taiwanese manufacturers around the 1999-2007 time frame. See:
