Auto warranties and vehicle service contracts are very different. A car manufacturer issues an auto warranty with a new vehicle purchase, while a vehicle service contract is a separate plan you can buy after your factory coverage ends. Yet, people who work in the car industry often refer to them interchangeably, leading to confusion for many drivers.
So what's the real difference? Learn more below.

| Length of coverage | Usually 3–5 years | Varies by provider; often up to 20 years or 200,000+ miles |
| Custom options | No | Yes, flexible plans and terms |
| Best for | New vehicles | Used or high-mileage vehicles |
An auto warranty, also known as a manufacturer’s warranty or factory warranty, is a written agreement that promises to pay for specific malfunctions or vehicle defects. Dealerships include these contracts with the purchase of a new car or a certified used vehicle, and they expire after a stated number of years or miles. Most include bumper-to-bumper and powertrain coverage.
Bumper-to-bumper warranties protect most of a car’s parts between the front and back bumpers and typically last 3 years or 36,000 miles, whichever comes first. A powertrain warranty is less extensive and protects components like the engine, transmission, drive axle, transfer case, and differential. Contracts typically last 5 years or 60,000 miles.
A vehicle service contract is a vehicle protection plan that helps pay for costly repairs after the manufacturer’s warranty expires. These are often marketed as auto protection plans or extended car warranties, though they’re technically not warranties under federal law. Coverage varies, so reviewing the contract helps you understand what’s included and what’s not.
An auto warranty provider is the vehicle’s manufacturer. For example, if you purchase a new Toyota vehicle, then the auto warranty provider is either Toyota (the manufacturer) or the dealership that sells you the car. A vehicle service contract provider can be a third party, a dealer, an automaker, or an insurance company. If you buy a vehicle service contract from a dealership, the administrator responsible for handling claims and processing payments may differ from the company that sold you the contract.
Auto warranty coverage starts when the vehicle is purchased or first put into service. Vehicle service contract coverage may begin when you sign the contract, after a waiting period (typically 30 days), or once the factory warranty ends.
Factory warranties typically include bumper-to-bumper and powertrain protection and may offer perks like roadside assistance. Vehicle service contracts vary widely. Some offer extensive protection, while others cover only essential parts. Many third-party vehicle service contracts also include roadside assistance, rental car reimbursement, and trip interruption. Some plans are transferable, which can boost resale value.
Auto warranties are built into the cost of a new vehicle. You won’t pay out of pocket for covered repairs during the contract term. Vehicle service contracts are separate purchases. Prices vary based on coverage, vehicle type, deductible, and provider. Some require full payment upfront, while others offer monthly payment plans.
New car buyers rely on factory warranties during the first years of ownership. Once that coverage ends, a vehicle service contract can provide added protection. Vehicle service contracts are especially valuable for used or high-mileage vehicles. If you want to keep your vehicle long-term but avoid unexpected car repair bills, a service contract can offer peace of mind.
There are several factors you should consider when searching for the right contract. Carefully review the following details before spending your money on an auto warranty or vehicle service contract:
Research providers, compare quotes, and read customer reviews before signing anything. Auto warranties come with new or certified used cars. Vehicle service contracts are purchased separately and can extend protection once factory coverage ends. If your car is older or sees frequent repairs, a vehicle service contract can be a smart way to reduce your out-of-pocket costs.
