A warranty is a promise
A warranty is a seller’s promise that a product will perform as intended. The warranty tells what items the seller will pay to fix after the sale, and for how long. A vehicle may have a "manufacturer warranty" that obligates the manufacturer to pay the cost of certain repairs. Or it may have a "dealer warranty" that obligates the dealer to pay. If a car comes with a warranty, you are entitled to get the warranty in writing from the dealership. Read the warranty carefully to learn what is covered, for how long, who pays for the repairs, and what you must do to keep the warranty in effect.
New and used car warranties
All new cars come with a manufacturer warranty. Tires, batteries, and dealer-installed options may have separate manufacturer warranties.
Some used cars come with a warranty. The Wisconsin buyers guide (used car window sticker) shows whether the used car comes with a "dealer limited warranty," or remaining "manufacturer warranty." If the vehicle comes with remaining manufacturer warranty, consult the warranty book or ask the seller what you need to do to have the warranty transferred into your name.
Many used cars come with no warranty at all. These cars show "AS-IS - NO WARRANTY" on their window sticker. When you buy a car as-is, the dealer and manufacturer are not responsible for paying for repairs after the sale.
What to do if your car needs warranty repairs
If your car needs repairs under a dealer warranty, consult the warranty or selling dealer to find out which repair shops are authorized to do your warranty repairs. If it needs repairs under a manufacturer warranty, you may take it to any dealer authorized to sell your make of car.
