How Subaru's CPO Warranty Works

Subaru's Certified Pre-Owned (CPO) warranty is a manufacturer-backed coverage plan that comes with vehicles sold through Subaru dealerships. Unlike a private sale, when you buy a CPO Subaru, the dealership has inspected the vehicle and Subaru stands behind it with specific warranty terms. The coverage is tied to the vehicle itself, not the owner, so it transfers if you sell the car later.

The warranty has two main parts: powertrain coverage and comprehensive coverage. Powertrain covers the engine, transmission, and drivetrain — the parts that make the car move. Comprehensive coverage protects against defects in other systems like electrical, climate control, and suspension. Both parts have different time and mileage limits, and whichever limit you hit first is when coverage ends.

You do not pay anything to use the warranty. When something covered breaks, you take the car to a Subaru dealership, they diagnose it, and if it falls under warranty, Subaru pays the repair. You may have a small deductible depending on the specific plan, though many CPO warranties have no deductible.

Key Takeaways

  • Subaru CPO warranty coverage lasts 7 years or 100,000 miles for powertrain and 5 years or 60,000 miles for comprehensive, whichever comes first.
  • The warranty transfers to a second owner if you sell the vehicle, though the second owner's coverage period is shorter.
  • You must use an authorized Subaru dealership for repairs to keep the warranty valid — independent shops do not count.
  • The warranty covers defects in materials and workmanship but not wear items like brake pads, wiper blades, or routine maintenance.
  • Subaru dealerships can tell you the exact remaining coverage when you buy, based on the vehicle's age and mileage at the time of purchase.

Powertrain Coverage: Engine, Transmission, and Drivetrain

Powertrain coverage is the longest part of the Subaru CPO warranty. It runs for 7 years or 100,000 miles from the vehicle's original in-service date — not from when you buy it. This means if the car was first sold three years ago and you buy it today, you have four years or 100,000 miles left, whichever comes first.

What powertrain covers: the engine block, cylinder head, internal engine parts, transmission, transfer case (on all-wheel-drive models), differentials, and axle shafts. If any of these fail due to a manufacturing defect or material failure, Subaru pays for the repair or replacement at a dealership.

What powertrain does not cover: routine maintenance like oil changes, spark plugs, and air filters; wear items like brake pads and clutch plates; damage from accidents, neglect, or using the wrong fuel; and repairs needed because you did not follow the maintenance schedule. If you skip oil changes and the engine seizes, that is not covered.

Comprehensive Coverage: Everything Else

Comprehensive coverage is shorter than powertrain but broader in what it touches. It lasts for 5 years or 60,000 miles from the original in-service date. This coverage includes electrical systems, air conditioning and heating, suspension, steering, brakes (the hydraulic system, not the pads), windows, locks, and other components not in the powertrain.

The intent of comprehensive coverage is to protect against defects in parts that are not wear items. If your air conditioning compressor fails at 40,000 miles, that is covered. If your power window motor stops working, that is covered. If your suspension strut leaks, that is covered — but if your brake pads are worn down from normal driving, that is not.

Like powertrain, comprehensive coverage requires you to use an authorized Subaru dealership and to have followed the maintenance schedule. It also does not cover damage from accidents, misuse, or environmental damage like rust from road salt (unless the rust is from a manufacturing defect in the paint or undercoating).

What Happens When You Transfer Ownership

If you sell your CPO Subaru to another person, the warranty transfers to them — but with a catch. The second owner gets 5 years or 60,000 miles of powertrain coverage from the original in-service date, not from when they buy the car. Comprehensive coverage does not transfer to a second owner at all.

This means if you bought a CPO Subaru with 30,000 miles on it and the original in-service date was two years ago, you have 5 years and 70,000 miles of powertrain coverage left. If you sell it two years later at 80,000 miles, the new owner has only 3 years and 20,000 miles of powertrain coverage left, and no comprehensive coverage. The dealership can calculate the exact remaining coverage for any vehicle before you buy.

Where You Can Get Repairs Done

You must use an authorized Subaru dealership for any repair you want covered under warranty. Independent mechanics, chain shops, and other dealers do not count, even if they are skilled and charge less. If you take your car to an independent shop and they fix something that would have been covered, Subaru will not reimburse you.

This is a real constraint. If you live far from a dealership or prefer your local mechanic, you need to know this before you buy. Some people factor the cost of driving to a dealership into their decision. You can find authorized Subaru service locations on Subaru's website or by calling a dealership near you.

The dealership will not charge you for the repair if it is covered under warranty. You may have a small deductible (often $0 or $50, depending on the specific plan), but the dealership will tell you this upfront. You do not need to pre-approve anything with Subaru — the dealership handles the warranty claim directly.

Maintenance Requirements and What Voids Coverage

Subaru requires you to follow the manufacturer's maintenance schedule for the warranty to stay valid. This means regular oil changes, fluid checks, and inspections at the intervals listed in your owner's manual. If you skip maintenance and a part fails as a result, Subaru can deny the claim.

For example, if you do not change your oil and your engine fails, Subaru will likely deny coverage because you did not maintain the vehicle. The dealership will check your service records when you bring the car in, so they will know if you have been keeping up. If you buy a used CPO Subaru, ask the dealership for the service history to see what the previous owner did.

Other things that void coverage: using the wrong type of fuel (like regular gas in a car that requires premium), modifications to the engine or drivetrain, racing or towing beyond the vehicle's rated capacity, and damage from accidents or environmental causes. If you modify your Subaru significantly, tell the dealership before you have warranty work done, because they may deny the claim.

How to Use Your Warranty When Something Breaks

When you think something is wrong with your CPO Subaru, call or visit an authorized Subaru dealership and describe the problem. You do not need to call Subaru first or get pre-approval. The dealership will schedule an appointment, inspect the vehicle, and diagnose the issue.

Bring your keys, the warranty documentation (which came with the car), and your proof of ownership. The dealership will run a diagnostic to confirm what is broken and whether it is covered. If it is covered, they will repair it at no cost (minus any deductible). If it is not covered, they will tell you the repair cost and ask if you want to proceed.

Repairs typically take a few days to a week, depending on what needs to be fixed and how busy the dealership is. Some dealerships offer loaner cars while yours is being worked on, though this is not may provide. Ask when you call to schedule whether a loaner is available.

Frequently Asked Questions

Does the warranty cover regular maintenance like oil changes and tire rotations?

No. The warranty covers defects in parts and materials, not routine maintenance. Oil changes, tire rotations, brake fluid flushes, and similar services are your responsibility and must be done to keep the warranty valid. Some dealerships offer separate maintenance plans you can purchase, but these are not part of the CPO warranty.

What if I buy a CPO Subaru with 50,000 miles already on it?

You have 2 years or 50,000 miles of powertrain coverage left (since powertrain runs 7 years or 100,000 miles from the original in-service date), and 1 year or 10,000 miles of comprehensive coverage left. The dealership will tell you the exact remaining coverage based on the vehicle's age and mileage when you buy it.

Can I take my CPO Subaru to any mechanic I want and still keep the warranty?

No. You must use an authorized Subaru dealership for any repair you want covered under warranty. If you take it to an independent shop, Subaru will not cover the cost, even if the repair would have been covered otherwise. This is a key difference between CPO and some other warranties.

What if the dealership says my car needs a repair that is not covered?

Ask the dealership to explain why it is not covered — whether it is outside the time or mileage limit, a wear item, or something excluded by the warranty terms. Get the explanation in writing. If you disagree, you can contact Subaru customer service, though Subaru will typically stand by the dealership's assessment if the vehicle was not maintained properly.

Does the warranty cover damage from an accident?

No. The warranty covers manufacturing defects and material failures, not damage from accidents, collisions, or misuse. If you are in an accident, your auto insurance would handle the claim, not the warranty. The warranty also does not cover environmental damage like rust or corrosion unless it is caused by a defect in the paint or undercoating.
