The bad capacitor problem is well documented, for example, Wikipedia “Capacitor plague” and Capacitor Lab. My symptoms are 1,2 and 3, and sometimes 7. However, it is very important in a critical application such as an air bag or automotive braking system that the components do in fact fulfill their useful lifeSeveral factors can prevent them from doing so.
