MBI vs. Extended Warranty: What To Know

Mechanical breakdown insurance and extended warranties are similar in that they can both reimburse you if your car breaks down due to a sudden internal failure. However, they often differ when it comes to how to obtain them, when you can qualify for them, how much they cost, what repairs they cover and how much you have to contribute out of pocket whenever you file a claim.

Continue reading for specific MBI vs. extended warranty comparisons that can help you decide whether you should add coverage to your car insurance policy or purchase a standalone plan.

Key Takeaways

Both mechanical breakdown insurance coverage and extended car warranties cover repairs if your car’s parts or systems experience a sudden mechanical or electrical failure.
Mechanical breakdown insurance is generally much cheaper than an extended warranty, but it may come with a higher deductible.
While MBI coverage may be restricted to newer cars with low mileage, you may be able to obtain a new extended warranty for an older, high-mileage vehicle.
You may be allowed to take your car to any auto shop with MBI, but an extended warranty may require you to visit an authorized dealership or auto shop.

What Is Mechanical Breakdown Insurance?

Mechanical breakdown insurance — also known as car repair insurance — is an optional car insurance add-on that covers damage to the parts of your vehicle caused by sudden breakdowns and other mechanical or electrical malfunctions. See the following table for an overview of the car parts that usually are and aren’t covered by MBI.^[1]

Generally Covered by MBI	May Not Be Covered by MBI
Suspension	Tires
Engine	Brake pads
Transmission	Drive belts
Drive train	Cooling system hoses
Cooling system
Air conditioning
Heating systems

How Does Mechanical Breakdown Insurance Work?

If you file a claim on your MBI policy after a covered loss, you will need to cover a portion of the costs out of pocket by paying a deductible. GEICO, for example, requires a $250 deductible for MBI claims.^[2] Keep in mind that your mechanical breakdown insurance won’t cover losses that are instead covered by physical damage insurance — such as damage from car accidents or storms — nor will it cover wear and tear, which is not covered by any type of auto insurance.

Deductible

Who Offers MBI?

Car repair insurance coverage is primarily sold by auto insurance companies as an add-on to existing car insurance policies. That said, you may also be able to obtain a standalone mechanical breakdown insurance plan from a bank or credit union.^[3] In this way, it is similar to gap insurance, which is offered by a variety of different financial institutions.

When Is MBI Available?

You may only be able to get MBI while your car is fairly new. For example, GEICO only offers new MBI policies for vehicles that are less than 15 months old and have no more than 15,000 miles on them. However, once they have purchased the initial policy, GEICO customers are allowed to renew their MBI for up to seven years or 100,000 miles — whichever comes first.^[2]

Because of these restrictions, it’s best to treat MBI as a backup in case a newer vehicle malfunctions rather than a Plan A for an older car with known mechanical problems.

How Much Does Mechanical Breakdown Insurance Cost?

The cost of mechanical breakdown insurance may range from as little as $30 per year to as much as $120 per year — with deductibles typically spanning from $100 to $500 — depending on the type of car you have and your policy’s coverage details.^[3] You must pay for MBI whenever you pay the rest of your car insurance premium, which usually occurs on a monthly, quarterly, semiannual or annual basis, depending on your insurance company.^[4]

What Is an Extended Warranty?

An extended warranty is a service contract that covers repairs or replacements of vehicle components that are damaged by sudden internal failures. As its name suggests, it is a paid extension of the manufacturer’s warranty that automatically comes with new cars. Free factory warranties usually expire after three years or 36,000 miles — whichever comes first — while extended warranties may add coverage for an extra two to seven years.^[5][6]

Although MBI and extended warranty claims both require deductibles, the deductibles for extended warranties are generally smaller.^[1] In addition, extended warranties may have much more lenient eligibility requirements than MBI policies. For example, Endurance offers vehicle service contracts for any car that is up to 20 years old with no mileage restrictions.^[7]

Who Sells Extended Warranties?

Extended auto service contracts are often sold by car dealerships, auto manufacturers and other third-party companies.^[8] Although insurance carriers don’t directly sell extended warranties, they may partner with other providers to offer comparable service contracts. For example, Allstate customers can secure a special deal on extended vehicle care plans administered by Pablo Creek Services — an Allstate subsidiary.^[9]

Coverage Tiers

There are three main types of extended warranties, as described in the table below. While vehicle protection plans that provide less coverage are naturally cheaper, those that offer broader coverage are generally considered to be a better value.^[10]

Warranty Type	Description
Powertrain warranty	Covers only the essential components responsible for moving your vehicle forward, such as the engine, transmission and drivetrain
Midlevel warranty	Covers most of your car’s major systems but excludes coverage for certain electronic and comfort features
Bumper-to-bumper warranty	Provides comprehensive coverage for nearly all of your car’s major parts and systems that may be subject to mechanical breakdowns

Common Exclusions

Your warranty company may reject claims involving racing, off-roading or defective aftermarket parts, depending on your coverage details.^[5] Meanwhile, oil filters and wiper blades may not be covered, and tires and batteries may require their own separate warranties.^[11] Additionally, while MBI may cover repairs performed by any facility, an extended warranty may only cover repairs performed by an authorized shop or the dealership that sold your car to you.^[2][8]

How Much Does an Extended Warranty Cost?

On average, bumper-to-bumper extended warranties cost about $1,000 per year, but the costs may be split into an initial down payment of $0 to $350 and monthly payments of $30 to $150 throughout the life of the warranty.^[12] However, some providers may require you to pay for your warranty in full with an upfront, lump-sum payment. Alternatively, the cost of your warranty may be rolled into your auto loan — in which case, you will have to pay interest on it.^[1]

Deductibles for extended warranties generally range from $50 to $250.^[1][12]
