Most extended warranty disputes — including the ones that result in denied claims — center on a single question: did the second thing break because of the first thing, or independently? Consequential damage coverage is the clause that answers that question in your favor.
Subaru Added Security includes consequential damage coverage as a standard feature of every plan. If a covered component fails and that failure causes damage to a second component, both are covered under the same claim. Most third-party extended warranty contracts handle this scenario differently — and that difference often shows up as a claim denial.
Quick Answer: Consequential damage coverage means that when a covered part fails and that failure damages adjacent or dependent components, the secondary damage is also covered. Subaru Added Security includes this. Third-party plans frequently exclude it, allowing them to deny repairs on everything a primary failure touched.
- Added Security covers the original failure and the damage it causes
- Third-party plans often list “damage resulting from a prior failure” as an exclusion
- Subaru’s integrated systems — AWD, EyeSight, STARLINK — make this coverage especially relevant
- One engine seal failure can become a multi-component repair; consequential coverage keeps it one claim
How Consequential Damage Works in Practice
Consider a realistic scenario: an oil seal on a Subaru’s turbocharged engine develops a slow leak. The seal itself is a covered component. Left undetected — or noticed only after some interval — the oil loss leads to increased friction and accelerated wear on internal engine components: camshaft bearings, piston rings, and valve train hardware.
Under a third-party extended warranty, the adjuster reviews the claim and notes that the internal engine wear was not caused by a sudden mechanical failure — it was caused by oil loss from a seal. The seal failure may be covered. The engine damage resulting from the seal failure may be denied as “damage resulting from a prior unrepaired condition” or “damage from lack of lubrication” — standard exclusion language in many third-party contracts.
Under Subaru Added Security, the consequential damage clause keeps the entire repair under one covered claim. The seal was the primary covered failure. The engine components damaged as a result are consequential damage — also covered.
Why Subaru’s Integrated Systems Make This More Important
Subaru vehicles use tightly integrated systems where a failure in one area can trigger problems in multiple others. This is by design — the systems are built to communicate and respond to each other — but it means that a single component failure can generate fault codes and operational anomalies across several modules.
AWD System: Subaru’s Symmetrical AWD uses electronic sensors to monitor wheel speed and distribute torque. A failed wheel speed sensor can cause the AWD management system to operate incorrectly, potentially stressing differentials and transfer case components. Under consequential damage coverage, secondary drivetrain wear resulting from the sensor failure falls within the claim.
EyeSight Technology: EyeSight’s cameras, processing module, and connected driver assist systems share data constantly. A failed steering angle sensor can cause EyeSight’s lane-keeping system to behave erratically, which may cause secondary diagnostic codes in the EyeSight control unit. Under Gold Plus with consequential damage coverage, the diagnostic and repair chain stays within one covered event.
Cooling System: A failed thermostat that causes the engine to run hot is a covered component under both Classic and Gold Plus. If that overheating episode causes a warped cylinder head or damaged head gasket, that secondary damage is consequential to the thermostat failure — covered under Added Security, potentially excluded under a third-party plan that defines the secondary damage as “overheating damage” rather than warranty coverage.
The Language to Watch For in Third-Party Contracts
Third-party extended warranty exclusion sections frequently contain phrases that effectively eliminate consequential damage coverage without using the term directly. Watch for:
- “Pre-existing condition” — Used to deny claims on components that were degraded before the claim, even if degradation was caused by a covered failure
- “Damage resulting from a prior failure” — Direct exclusion of consequential damage
- “Lack of maintenance” — Broad language that can be applied to any failure where maintenance records are incomplete
- “Damage from overheating” — Excludes secondary engine damage even when overheating was caused by a covered component failure
Subaru Added Security’s coverage language is administered by Subaru of America directly. There is no independent adjuster looking for exclusions — the repair is handled between the service advisor and Subaru’s warranty system.
A Note on Subaru’s Boxer Engine Design
Subaru’s horizontally-opposed boxer engine positions cylinders on their sides rather than vertically, which affects how oil distributes at startup and how certain seals and gaskets are loaded over time. This design produces outstanding center-of-gravity characteristics but creates specific wear patterns that are characteristic of the platform.
Consequential damage coverage is particularly relevant for boxer engine owners because the engine’s layout means that a single oil seal or gasket failure can distribute oil to areas of the engine that would not be affected in a conventional design. Added Security’s coverage accounts for this — the claim process does not require proving that each damaged component failed independently.
