How Infiniti's CPO warranty works

Infiniti's certified pre-owned (CPO) warranty is a manufacturer-backed protection plan that covers defects in parts and workmanship on used vehicles that have passed Infiniti's inspection process. The warranty runs from the date you purchase the vehicle, not from when it was originally sold, and covers both parts and labor at any Infiniti dealership.

The coverage is split into two tiers: a bumper-to-bumper section that covers most vehicle systems, and a powertrain section that covers the engine, transmission, and drivetrain for a longer period. You do not pay a separate fee for this warranty — it is included as part of the CPO certification when you buy the vehicle.

Key Takeaways

  • Infiniti CPO vehicles come with a six-year or 100,000-mile bumper-to-bumper warranty, whichever comes first, starting from your purchase date.
  • The powertrain warranty extends to ten years or 120,000 miles from your purchase date, covering the engine, transmission, and drivetrain components.
  • The warranty covers defects in parts and labor at any Infiniti dealership, but does not cover routine maintenance like oil changes, tire rotation, or wear items.
  • You must follow Infiniti's recommended maintenance schedule to keep the warranty valid; skipping scheduled service can void coverage.
  • The warranty transfers to a second owner if you sell the vehicle, though coverage may be reduced depending on when the transfer occurs.

Bumper-to-bumper coverage: what is included

The bumper-to-bumper section covers virtually every system in the vehicle except for items that wear out through normal use. This includes the electrical system, air conditioning, heating, audio, navigation, suspension, steering, brakes, and body panels. If a component fails due to a manufacturing defect, Infiniti will repair or replace it at no cost to you.

This coverage lasts for six years or 100,000 miles from the date you purchase the vehicle. Once you hit either limit, the bumper-to-bumper protection ends, though the powertrain warranty continues. The warranty is valid at any Infiniti dealership in the United States, so you are not locked into a single location for repairs.

Powertrain coverage: engine, transmission, and drivetrain

The powertrain warranty is the longer-lasting portion of Infiniti's CPO coverage. It protects the engine, transmission, transfer case, drive axles, and other drivetrain components from defects in materials and workmanship. If your transmission fails or your engine develops a covered defect, this warranty pays for the repair or replacement.

Powertrain coverage runs for ten years or 120,000 miles from your purchase date, giving you significantly more protection than the bumper-to-bumper section. Like the rest of the warranty, it is honored at any Infiniti dealership and covers both parts and labor. Wear items like spark plugs, belts, and hoses are not covered under this section unless they fail as a result of a defect in another covered component.

What the warranty does not cover

Infiniti's CPO warranty does not cover routine maintenance or items that wear out through normal driving. Oil changes, tire rotation, brake pad replacement, wiper blades, air filters, and coolant flushes are your responsibility. The warranty also excludes damage from accidents, misuse, neglect, or modifications to the vehicle.

Wear items like brake rotors, clutch plates, and suspension bushings are generally not covered unless the failure is caused by a defect in another covered part. Cosmetic damage, rust, and corrosion are also excluded. If you fail to follow Infiniti's recommended maintenance schedule, the manufacturer may deny a warranty claim, so keeping service records is important.

Maintenance requirements to keep warranty coverage valid

Infiniti requires that you follow the manufacturer's recommended maintenance schedule to keep your CPO warranty in force. This typically includes oil and filter changes every 3,000 to 6,000 miles (depending on the model year and engine type), tire rotation, and inspections at specified intervals. You can have this work done at an Infiniti dealership or at an independent shop, but you must keep records of all service performed.

If you skip scheduled maintenance and a component fails, Infiniti may investigate whether the failure was related to the missed service. For example, if you do not change your oil on schedule and your engine fails, the manufacturer could deny the claim. Keeping receipts and service records protects you in this situation, so save everything related to your vehicle's upkeep.

What happens if you sell the vehicle

Infiniti's CPO warranty transfers to a second owner if you sell the vehicle, which can make your car more attractive to buyers. However, the coverage changes after the transfer. The second owner receives a six-year or 100,000-mile bumper-to-bumper warranty and a ten-year or 120,000-mile powertrain warranty, but these periods run from the original purchase date, not from when the second owner buys the car.

This means if you sell the vehicle three years after you bought it, the second owner has only three years of bumper-to-bumper coverage remaining (or until 100,000 miles, whichever comes first). The powertrain warranty similarly has seven years left. The second owner still benefits from the warranty, but the clock does not reset.

How to file a warranty claim

If a covered component fails, take your vehicle to any Infiniti dealership and explain the problem. The dealership will diagnose the issue and determine whether it is covered under the warranty. If it is, they will perform the repair at no cost to you — you pay nothing for parts or labor.

Bring your proof of purchase and service records with you. The dealership may ask to see your maintenance history to confirm you have followed the recommended schedule. If everything is in order, the repair is covered. If the dealership denies your claim, you can contact Infiniti customer service to appeal the decision.

Frequently Asked Questions

Can I transfer the warranty if I sell my Infiniti CPO vehicle?

Yes, the warranty transfers to the next owner, but the coverage period does not reset. The second owner gets the remaining time on both the bumper-to-bumper and powertrain warranties, calculated from the original purchase date. This can be a selling point when you trade in or sell your vehicle.

Does the warranty cover regular maintenance like oil changes?

No. Oil changes, tire rotation, air filter replacement, and other routine maintenance are your responsibility. However, you must keep up with scheduled maintenance to keep the warranty valid — skipping service can result in denied claims if a component fails.

What if a repair is denied as not covered?

Contact Infiniti customer service with your vehicle identification number (VIN), purchase date, and details about the repair. You can request a review of the denial. Bring your service records to show you have maintained the vehicle according to the manufacturer's schedule.

Does the warranty cover accident damage or damage from misuse?

No. The warranty covers defects in parts and workmanship only. Damage from accidents, collisions, off-road use, or modifications is not covered. Cosmetic damage and rust are also excluded.

Can I have warranty work done at an independent mechanic instead of a dealership?

The warranty is only valid at Infiniti dealerships. Independent shops cannot perform covered repairs under the warranty. However, you can have routine maintenance done elsewhere as long as you keep records to show you have followed the manufacturer's schedule.
