Car Warranty vs. Car Insurance: What’s the Difference?

When your car is damaged or breaks down, it’s not always clear who’s going to pay for repairs. If you have car insurance and a car warranty, you can figure out who might pay by how the issue happened:

Essentially, car insurance protects you and your car in case of accidents and external damage. If someone hits your car or a tree falls on it, car insurance can cover the cost of the repair. If you damage someone else’s car or property with your car, your insurance’s liability coverage can pay for it.

A car warranty covers the cost of repairs in case of defective parts, mechanical or electronic failures. It’s a guarantee that your car will work like it’s supposed to. Your new car comes with a manufacturer’s or factory warranty, typically lasting three to five years. You can also opt to purchase an extended warranty to cover repairs after the factory warranty expires.

Car insurance covers the cost of damage to your car due to collisions and other accidental events.

Other types of car insurance, such as collision insurance and comprehensive insurance, can pay for damage to your car from natural disasters, theft, vandalism and incidents like hitting a curb.

Example: You get into an accident with another car. You and the other driver both file a claim with your insurance companies. The driver found to be responsible for the accident pays for the damages. If you’re found responsible, your monthly insurance rate will typically go up.

Car warranties cover the cost of the parts and labor needed to fix internal defects and mechanical failures. There are two main kinds of warranty:

The “bumper-to-bumper” warranty that comes with your brand-new car from the manufacturer typically covers major repairs for the first three years or 36,000 miles, whichever comes first. Some cars also come with a longer “powertrain” warranty that covers parts like the engine and transmission for five to 10 years, or a higher mileage limit.

Example: Your transmission fails. You bought the car new a year ago. You bring the car into the dealership you purchased it from, and they work with the manufacturer to replace the transmission at no cost to you.

An extended car warranty, more accurately a “vehicle service contract,” covers the cost of repairs after your factory warranty expires. Covered parts vary depending on the company that sells you the warranty and which plan you choose. Extended warranties typically last two to seven years.

Example: Your air conditioning stops working. You pay $60 a month for an extended warranty plan on your used car that includes air conditioning. You take your car to a certified repair shop and file a claim with your extended warranty company. If the claim is approved, you pay a $200 deductible for the repairs, and the warranty covers the rest.

For the most part, car warranties and car insurance don’t cover routine car maintenance or normal wear-and-tear items such as oil changes, tire changes and windshield wiper replacement. Some warranties do offer add-on plans that cover these items.

Technically, no, a car warranty and car insurance do not usually overlap. Though some insurance companies offer an add-on called Mechanical Breakdown Insurance (MBI). It works a lot like a warranty but is billed through your insurance provider.

MBI pays for repairs or replacement parts when your car breaks down, even if there’s no accident or other external cause. MBI is usually less expensive than an extended warranty, but may include higher deductibles. You’ll need to purchase it early on, though: For example, GEICO only offers MBI coverage for cars with less than 15,000 miles and newer than 15 months old.
