Cooling system related failures.
 
As far as catastrophic failure of the engine itself, overheating. Many cars with working engines are junked due to rust-out or crashing.

While this could easily vary with engine design/make

I would think Cooling system failure by a large margin.

That is what killed my Cherokee.

It's a race between the RMS or the tranny as to what kills my Rav4.

I see how many miles you have on your cars, we got a measly 111,000 ... wife loved her car and was very upset about replacing it!
 
It varies by design and ect, but by far I have cooling or seal failures too be most common.

A 3400/3800 is dated and they have ago on them. A intake or head gasket is many time more money then the vehicle is worth.
One just left the barn with heads, seal, fluid,etc. The bill was to customer $900 before the extras, Ditto a totaled car for most.

Car itself: Maybe they crash into something or rust, as mentioned somewhere above.

Engine: I say cooling system issues because those can lead to bad head gaskets, or engine part damage, and either slowly or instanty affect the engine.

Boat engines its a manifold issue and the engine injests water.
 
Definatly overheating. When I went to drivers ed we were told to pull over asap if the gauge showed hot. People today think its ok to drive with the needle in the red instead of calling a tow truck..

I'd say 90% of the cars I see that got hot are cooked. People drive until the thing stops running.

What new cars have a real needle?

my jeep shows coolant temp(if it put it on that screen) but no gauge.

My previous subarus dont have anything except a double idiot light
blue for "take it easy I'm cold" and red for you are about to explode.
 
Here in Phoenix, it's usually either a coolant issue or A/C failure costing more than the car is worth to repair. Back when I lived in Chicago, it was usually either rust or antifreeze failure.

Or, in both places, some kind of driver error or weather-related crash.
 
The one I hear about most from friends here are timing belts that finally let go. I'm not sure if it's just my friend group, or the population overall, but no one seems to change them, or buy high mileage cars with the original belt, and drive them till they snap. Mostly recently, a lady friend killed her Subaru.

My Cherokee has a coolant temp icon (looks just like the gas level thing) that's always there even if you're not on the coolant temp display.

Motor oil related failures not caused by running the oil low enough that the pickup sucks air simply don't happen.
As many have noted, loss of coolant kills more engines than any other single cause, maybe all other causes combined.
Most newer cars lack coolant temperature gauges, not that the average driver would pay any attention to a gauge anyway.
A gauge can save your bacon if you pay attention, though.
When the coolant temperature light illuminates, it means shut down now, not ten miles from now.
Do that and you might just save the engine. Keep on driving and you're probably looking at major and maybe economically unfeasible work to return the engine to service.
