Does auto insurance cover a blown engine?
A standard auto policy does not pay for a blown engine caused by wear, age, or lack of maintenance — that's mechanical failure, not a covered peril.
What flips the answer
- Covered when
The engine was destroyed as part of a covered peril — a collision, a flood, or a fire — and you carry the matching collision or comprehensive coverage.
- Covered when
You bought optional Mechanical Breakdown Insurance (MBI), or the failure is still under a manufacturer or extended warranty.
- Not covered when
The engine failed from wear, high mileage, overheating, or missed maintenance — that's an excluded mechanical breakdown.
Collision and comprehensive coverage pay for sudden, external events — a crash, a theft, a fire, a falling tree. An engine that dies from mileage, overheating, a skipped oil change, or ordinary wear is a mechanical breakdown, and mechanical breakdown is specifically excluded from a standard auto policy.
There are two situations where the engine damage can be covered. If the engine was destroyed as part of a covered event — a collision, a flood, or a fire — then the collision or comprehensive claim can include the engine. And if you bought optional Mechanical Breakdown Insurance (MBI) or still have a manufacturer or extended warranty, that's the product built to pay for internal failures.
So the answer turns entirely on cause. A blown engine from a wreck can be covered; a blown engine from a worn-out timing belt almost never is.
That's the general answer. Yours is written in your actual policy.
