The warranty on a used car is not a single, standard length. It depends entirely on the type of warranty provided. The most common scenarios are: the remaining balance of the original manufacturer's warranty, a specific warranty from a Certified Pre-Owned (CPO) program, a limited warranty from the selling dealership, or a separate third-party service contract (often called an "extended warranty") that you purchase. Many used cars, especially older ones sold "as-is," have no warranty at all.
The gold standard for used car coverage is a factory-backed CPO program. These typically extend the original bumper-to-bumper and powertrain warranties. For example, a popular CPO program might offer a 7-year/100,000-mile limited warranty from the original vehicle in-service date. It's crucial to verify the exact coverage and deductible.
If you're buying from a private seller or a small lot, the car is almost certainly sold "as-is," meaning you assume all repair costs after the sale. Some larger dealerships may include a short-term "dealer warranty," often 30-90 days, covering major components like the engine and transmission. Always get any warranty terms in writing and read the fine print to understand what is and isn't covered.
| Warranty Type | Typical Length (Time/Mileage) | Key Coverage | Common Provider |
|---|---|---|---|
| Remaining Factory Warranty | Varies by original in-service date | Bumper-to-bumper, Powertrain | Vehicle Manufacturer |
| Certified Pre-Owned (CPO) | 1-2 years/up to 100,000+ total miles | Comprehensive, Powertrain | Manufacturer (e.g., Honda, Toyota) |
| Dealer Warranty | 30 days to 1 year | Major components only | Selling Dealership |
| Third-Party Service Contract | 1-5 years/12,000-100,000 miles | Varies by plan (Powertrain to Comprehensive) | Companies like Endurance, CarShield |
| "As-Is" | No Warranty | None | Private Sellers, Many Independent Lots |
Your first step should be to get the Vehicle Identification Number (VIN) and check with the manufacturer to see if any original factory warranty remains transferable. This due diligence is the best way to get peace of mind with a used vehicle purchase.

Don't assume there's a warranty. Most used cars from private sellers are "as-is"—you buy it, you own any problems. Big dealerships might include a short 90-day powertrain warranty, but read the details. The best bet is a Certified Pre-Owned (CPO) car from a brand like Honda or Toyota; they come with a real, extended factory warranty that can last for years. Always ask for the warranty document and read the exclusion list before you sign anything.

It's all over the map. If the original factory warranty is still active, it transfers to you. Certified Pre-Owned vehicles have the best and longest warranties, sometimes adding over a year of coverage. But the minute you drive off a lot with a basic used car, the only warranty might be your own savings account. The answer isn't simple—it’s in the paperwork. You have to ask the seller specifically what’s covered and for how long.

Focus on the source of the warranty. A manufacturer's CPO warranty is strong because it's backed by the brand itself. A dealer's warranty is only as good as that specific dealership's reputation. A third-party warranty can be complicated with many loopholes. The length is important, but the strength of the company honoring it is what really matters. A one-year warranty from the manufacturer is more valuable than a three-year warranty from a company you've never heard of.
