Your question is sort of backwards, perhaps you meant what causes engine failure? Engine failure causes...the engine to fail. If someone told me their engine failed I would take it to mean that it stopped running, or wouldn't start.
HEadgasket failure, internal oil cooler leak.
Age, carbon deposits, and driving an engine with a misfire.
causes of corporate failure
Causes include internal failure, solenoid malfunction, wiring malfunction, engine/trans sensor failure, pcm failure.
The check engine light comes on when there is an emissions related failure. You need to have the system checked for trouble codes to know possible causes.
If it blows when trying to crank the engine, the starter is probably the failure.
Gasket failure (they don't last forever). Warping of the two mating surfaces, loose bolts.
The light comes on when there is an emissions related failure and the pcm sets a code.
So you don't have vehicle or engine failure that causes a serious collision with injury or death.

No oil pressure, engine noise, engine failure.
