What Does a Manufacturer’s Car Warranty Cover? A Complete Guide
When you buy a new car, one of the most reassuring parts of the purchase is the manufacturer’s warranty. But what exactly does it cover—and what doesn’t it? Whether you’re driving a fresh-off-the-lot SUV or still under warranty from a few years back, understanding the ins and outs of coverage, including how to check warranty by VIN, can save you thousands and a ton of stress.
Let’s break down the different types of manufacturer warranties, what you can expect to be covered, and how to handle warranty claims or extensions, including guidance on “how to check my warranty on my car” to understand your current coverage.
The Basics of a Manufacturer’s Warranty
A manufacturer’s car warranty is a promise from the automaker that your vehicle will function as intended for a specific period or mileage. If a part breaks because of a factory issue, they’ll fix it for free.
Most new cars include more than one type of warranty.
