Are Turbochargers Covered by an Extended Warranty?

What Does a Turbocharger Do?

A turbocharger uses energy from the engine's exhaust gases to spin a turbine.

That turbine is connected to a compressor wheel that forces additional air into the engine. With more air available, the engine can burn more fuel efficiently and produce significantly more power from a relatively small displacement.

That's why many modern four-cylinder turbocharged engines can produce horsepower that once required much larger V6 or V8 engines.

Because turbochargers play such an important role in engine performance, they're commonly covered under many comprehensive vehicle service contracts.

If you're comparing protection plans, our guide to What Does an Extended Car Warranty Actually Cover? explains how different levels of coverage compare.

Are Turbochargers Usually Covered?

Many vehicle service contracts include turbochargers, especially under:

• Powertrain Plus coverage
• Inclusionary coverage
• Exclusionary coverage

Some powertrain contracts also include factory-installed turbochargers because they're considered part of the engine assembly.

However, coverage isn't universal. Every vehicle service contract is different, so it's important to review the covered components listed in your agreement.

Why Turbocharger Repairs Can Be Expensive

Turbochargers are precision-engineered components.

Depending on the vehicle, replacing a turbocharger can involve:

• Removing exhaust components
• Disconnecting oil and coolant lines
• Replacing gaskets and seals
• Programming or recalibrating engine controls in some cases

Many modern vehicles also package turbochargers deep within the engine compartment, increasing labor time.

As a result, turbocharger repairs commonly cost well over $1,500, with some luxury and performance vehicles costing substantially more.

Common Signs of Turbocharger Problems

A failing turbocharger can produce several different symptoms.

Some of the most common include:

• Noticeable loss of power
• Slower acceleration
• Excessive exhaust smoke
• Whining or siren-like noises
• Poor fuel economy
• Check engine light
• Increased oil consumption

These symptoms don't necessarily mean the turbocharger itself has failed.

Vacuum leaks, boost leaks, sensors, wastegate problems, ignition issues, and fuel system faults can all create similar symptoms. Proper diagnosis is essential before replacing major components.

How Turbocharger Problems Are Diagnosed

Diagnosing turbocharger issues involves much more than simply scanning for trouble codes.

A technician may perform:

• Computer diagnostics
• Boost pressure testing
• Intake system inspection
• Oil supply inspection
• Wastegate operation testing
• Turbo shaft play inspection
• Smoke testing for boost leaks
• Manufacturer-specific diagnostic procedures

These tests help determine whether the turbocharger itself has failed or whether another component is causing the problem.

What Related Components May Be Covered?

A turbocharger doesn't operate by itself. Several supporting components help the system function properly.

Wastegate

The wastegate regulates turbocharger boost pressure.

Many higher-level vehicle service contracts include wastegate assemblies when they're integral to the turbocharger.

Intercooler

The intercooler cools compressed intake air before it enters the engine.

Coverage varies considerably by provider. Some contracts include intercoolers, while others treat them separately.

Oil Supply Components

Turbochargers rely on a constant supply of clean engine oil for lubrication.

Depending on the agreement, certain oil supply components associated with the turbocharger may also be covered.

Sensors

Turbocharged engines often depend on boost pressure sensors, MAP sensors, and other electronic controls.

Coverage for these sensors varies by agreement.

Does Coverage Depend on the Type of Vehicle Service Contract?

Yes.

The level of protection you choose often determines whether turbocharger components are covered.

Powertrain Coverage

Some powertrain contracts include factory-installed turbochargers because they're considered engine components, while others may not.

Powertrain Plus

Powertrain Plus plans commonly expand coverage to include additional engine components, including turbochargers.

Inclusionary Coverage

Coverage depends on whether the turbocharger and related components are specifically listed in the agreement.

Exclusionary Coverage

Exclusionary vehicle service contracts generally provide the broadest protection and often include turbochargers unless they're specifically excluded.

For a deeper understanding of these coverage levels, see Inclusionary vs. Exclusionary Warranty: What's the Difference? and What Is an Exclusionary Extended Warranty or VSC?.

What Usually Isn't Covered?

Even comprehensive vehicle service contracts have exclusions.

Common examples include:

• Routine maintenance
• Oil changes
• Damage caused by contaminated oil
• Failures resulting from inadequate lubrication
• Performance modifications
• Aftermarket turbocharger upgrades
• Racing or competition use
• Accident damage
• Neglect

Because turbochargers depend heavily on clean engine oil, skipping oil changes or operating the engine with low oil levels can contribute to premature failure.

How the Claims Process Typically Works

If your repair facility determines the turbocharger has failed, it will generally diagnose the cause of the problem before replacing any components.

Before covered repairs begin, the repair shop typically contacts the vehicle service contract administrator to request authorization. The administrator reviews the diagnosis, confirms whether the failed component qualifies for coverage under the agreement, and may request additional information before approving repairs.

This process helps ensure repairs meet the terms of the contract. It doesn't guarantee every turbocharger repair will be approved, particularly if the failure resulted from an excluded cause.

Can You Help Prevent Turbocharger Failure?

While no turbocharger lasts forever, proper maintenance plays an important role in its longevity.

Following the manufacturer's recommended oil change intervals, using the correct engine oil, checking oil levels regularly, and addressing warning lights promptly can all help reduce unnecessary wear.

Even with excellent maintenance, however, turbochargers can eventually fail due to age, mileage, or normal mechanical wear.

Should You Buy a Vehicle Service Contract Just for the Turbocharger?

Probably not.

Turbocharger repairs can be expensive, but they're only one part of your vehicle's engine.

A comprehensive vehicle service contract is designed to help protect many major systems—including the engine, transmission, cooling system, fuel system, electronics, steering, and suspension—against unexpected mechanical breakdowns.

Final Thoughts

Turbochargers are commonly covered by many vehicle service contracts, especially under Powertrain Plus, inclusionary, and exclusionary plans. However, coverage ultimately depends on your specific agreement and the reason for the failure.

Understanding how turbochargers work, what supporting components may also be covered, and what exclusions commonly apply can help you make a more informed decision before an expensive repair becomes necessary.
