Time, age, moisture, ESD (electrostatic discharge), faulty part, poorly sodered connections, improper voltage running through fried it. All sorts of things.

A big mechanical relay like these solenoids isn't going to be taken out by ESD (unless you are talking about a bolt of lightning as ESD). Even an EMP probably wouldn't do the job.

What probably kills most of them is contact arcing or an open in the windings. The heat and vibration of being mounted in the engine compartment don't really help things either.
