Buying a Used Car: How to Check What Factory Warranty Is Left

A used car that is only a few years old may still have part of its factory warranty. That remaining coverage has real value, but you need to confirm it rather than take a seller's word for it. Here is how to figure out what is left and what it covers.

Factory warranties usually transfer

In most cases, the manufacturer's new-car warranty stays with the vehicle, not the owner. If the car is still within the time and mileage limits, the next owner gets the rest of the coverage.

There is one important exception. A few brands give a longer powertrain warranty only to the original owner. For example, Hyundai, Kia, Genesis and Mitsubishi offer a powertrain warranty of 10 years or 100,000 miles, but that longer term generally applies to the original owner. Later owners usually get a shorter powertrain term. Check the brand's warranty booklet for the exact rules for that model year.

Start with the in-service date

The warranty clock usually starts on the in-service date, which is the day the car was first sold to a retail customer or first put into use, such as a dealer demo or fleet vehicle. It is not the model year.

A car from one model year might have gone into service many months later, which can work in your favor. Or a car used as a loaner might have started its warranty before it was ever sold to anyone.

To find the in-service date:

1. Ask a franchised dealer for that brand to look up the VIN.
2. Check the manufacturer's owner website or app, which sometimes shows warranty status.
3. Ask the seller for the original sales paperwork.

Do the math on time and mileage

Most factory coverage ends at whichever comes first: the time limit or the mileage limit. For example, Toyota's basic coverage is 3 years or 36,000 miles and its powertrain coverage is 5 years or 60,000 miles. A Toyota with 30,000 miles that went into service three and a half years ago has no basic coverage left, even though it is under the mileage limit. It would still have powertrain coverage until it reaches 5 years or 60,000 miles.

Write down both the remaining time and the remaining miles for each type of coverage. Terms can vary by model year, so confirm the numbers for the car you are looking at. Our makes page has brand-by-brand guides.

Know the types of coverage

A factory warranty is usually several warranties in one:

• Basic or bumper-to-bumper: Covers most parts, with exceptions for wear items.
• Powertrain: Covers the engine, transmission and drive parts, usually for longer.
• Corrosion: Covers rust-through of body panels, often for a longer term.
• Emissions: Covers certain emissions parts under federal rules.
• Hybrid or EV battery: Often a separate, longer term on electrified vehicles.

Check for things that can affect coverage

Some situations can limit or void factory coverage. Ask about:

• A salvage, rebuilt or flood title, which often voids the factory warranty
• Odometer problems or a replaced instrument cluster
• Major modifications to the engine or drivetrain
• Open recalls, which should be done at no cost regardless of warranty

A vehicle history report and a dealer VIN lookup can help you catch these.

Get service records and an inspection

Even with warranty left, missing maintenance can cause trouble with future claims. Ask for service records. Then have an independent mechanic inspect the car before you buy. If you are buying from a dealer, ask whether any warranty repairs were already done and what the car's recall status is.

Plan for when coverage runs out

Once you know how much warranty is left, you can plan. If basic coverage ends in a few months, consider whether you want a service contract to pick up afterward. Some plans can be bought while factory coverage is still active. Our auto warranty page explains how service contracts work alongside factory coverage.
