What causes a car computer to go bad?

Vibration and Stress.

Vibration as well as thermal stress has also been known to cause control modules to go bad.

This is because they can cause tiny cracks to form in the control module's circuit boards.

However, unlike water damage, this type of damage to a control module is repairable.
