What “Factory warranty” means
Most new cars come with a comprehensive warranty, commonly around 3 years/36,000 miles, and a powertrain warranty, commonly 5 years/60,000 miles. Some brands offer longer terms, and some long powertrain warranties apply only to the original owner. There are also separate warranties for emissions parts, corrosion and, on EVs and hybrids, the high-voltage battery.
Warranties cover defects in materials or workmanship, not wear items like brakes and tires, and not damage from accidents or neglect.
How it shows up at the dealership
When buying used, check the original in-service date: coverage counts from when the car was first sold, not when you buy it. On new cars, salespeople may suggest a service contract “to protect” you while the factory warranty is still running for years.
Coverage usually transfers to the next owner automatically, but some extended terms do not. If you’re buying used, confirm what remains for you, not just for the original buyer.

How much coverage is left on a used car
| In-service date | June 2023 |
| Mileage now | 28,000 |
| 3yr/36k comprehensive | ends June 2026 (already expired) |
| 5yr/60k powertrain | until June 2028 or 60,000 miles |
Terms are examples; check your brand’s warranty booklet or the manufacturer’s VIN lookup.
What to do
- Look up remaining coverage by VIN with the manufacturer or a brand dealer.
- Keep maintenance records; they help if a claim is questioned.
- Before coverage ends, get any known issues documented on a repair order.
What to say
“Can you look up the in-service date and remaining factory coverage on this VIN and print it for me?”
