Starter Motor
Manufacturer warranty
Potentially covered if the vehicle is still within its bumper-to-bumper or comprehensive warranty period.
Powertrain coverage
Often not included, for the same reason as the alternator — it's generally treated as an electrical component rather than part of the engine/transmission/drivetrain.
Exclusionary service contract
Possibly covered depending on the contract's component list and any electrical-system exclusions.
Auto insurance
Mechanical or electrical failure of a starter motor is normally not something standard auto insurance responds to.
Manufacturer recall
Only applicable if there's an open recall specifically covering the starter or its circuit on that vehicle.

This is general guidance about how these coverage categories typically work, not a diagnosis or a claim about any specific provider, manufacturer or your own contract. Always check your actual warranty booklet or service contract for what's really covered.
