One capacitor on a tank array would definitely reduce its total capacitance, but they are nearly always in parallel and would not cause a failure of the whole tank, and the device would be inoperative if the output of the array was shorted.
I'm skeptical that losing one capacitor in the array would cause the failure mode you're describing. Especially if the age of the devices is considered, the array would have been designed with margin to withstand capacitance loss as the device ages.

In many cases, having a cap fail open results in a higher current draw which kills the unit if left in operation for too long. This is the case on some of the off-road lighting I manufacture. If one cap is present and fails open at ground, the circuit overloads. If the cap is connected to ground but not the rest of the circuit, the circuit doesn't operate. Regardless, one component being off can cause a whole chain of maladies.
