For drivers concerned about paying for an unexpected repair — whether because you’re low on savings or on a tight monthly budget — mechanical breakdown insurance (MBI) offers an additional financial cushion for a relatively affordable monthly cost. It ’s cheaper than an extended warranty, too.
MBI is an optional coverage that offers car repair insurance for mechanical systems failures (air conditioning, electric, exhaust, etc.) due to faulty parts, defects, and other issues. But policies also come with some limitations.
Ultimately, only you can decide if an MBI policy is right for you — and this article provides everything you need to make that decision.

What Is Mechanical Breakdown Insurance?
Mechanical breakdown insurance (MBI) is a type of car insurance that covers the repair cost of unexpected mechanical failures or breakdowns on new cars. MBI plans typically cover repairs or replacements of major mechanical components — such as the engine, transmission, and electrical system — due to defects or failures that aren’t caused by accidents.
For a small additional cost, MBI can provide peace of mind and financial protection against costly repair bills for vehicles outside the manufacturer’s warranty.
How Does Mechanical Breakdown Insurance Work?
)
Policyholders pay an MBI premium to an insurance company agreeing to cover the costs to repair defects or other malfunctions. You can submit a claim to the insurer when your car breaks down. The insurer will assess the claim and issue payment (minus the deductible) up to coverage limits if the repairs are covered under your policy.
MBI is usually only available for cars under a specific mileage and age (i.e., MBI is typically not available for older vehicles). For example, GEICO only issues MBI policies to cars newer than 15 months old and with less than 15,000 miles. You can renew your policy for up to seven years or 100,000 miles, whichever happens first.
What does MBI cover?
Mechanical breakdown insurance covers breakdowns and mechanical failures of vehicle systems that aren’t covered by your warranty. The exact components covered will depend on the policy and insurer, but it’s common for an MBI policy to cover the following systems:
Brakes
Electrical systems
Emissions components
Engine components
Fuel systems
Steering systems
Suspension components
Transmissions
Some companies also include roadside assistance and rental car coverage with MBI insurance policies. But expenses like routine maintenance (tune-ups, alignment, fluid changes, tires, etc.) and breakdowns resulting from misuse, improper maintenance, and corrosion aren’t typically covered.
What’s the difference between MBI and an extended warranty?
MBI and extended car warranties (or vehicle service contracts) are similar but usually differ in what events or mechanical systems they cover. Coverage varies among policies and warranties, but all extend beyond what the typical manufacturer warranty covers. Both exclude routine maintenance and general wear and tear.
The main difference between the two products is the cost. ConsumerAffairs reports the average extended car warranty costs around $1,000 per year. MBI costs a fraction of that.
When choosing between the two, compare what’s covered and up to what amounts. It’s possible an extended warranty will offer you better coverage, which may make the higher price worth it.
Do You Need Mechanical Breakdown Insurance?
If you have concerns about covering unexpected repairs, mechanical breakdown insurance can offer you peace of mind. It’s a great option for people without emergency savings. Coverage is so inexpensive that a single claim can recoup all or most of that year’s premiums.
For example, replacing a faulty A/C compressor runs between $1,546 and $1,705, according to Kelley Blue Book (KBB). But many common repairs are only a few hundred dollars.
For some, coverage isn’t worth it. Mechanical breakdowns occur more often after a vehicle has more than 100,000 miles. Issues that occur before then often result from normal wear and tear or improper maintenance, which would exclude the repair from coverage.
Ultimately, it depends on what type of risk you feel comfortable taking. MBI can pay for itself if you end up needing a repair. But if you never make a claim over the course of your policy, you’ve most likely spent around $700 for unused coverage.
How Much Does Mechanical Breakdown Insurance Cost?
)
Mechanical breakdown insurance costs range depending on several factors. Many policies cost around $100 per year (or roughly $8 per month), but it’s also worth considering the deductible amounts. The MBI deductible will typically range between $250 and $500, which you’ll pay out of pocket when you file a claim.
The final consideration is the indirect costs of making an MBI claim. While MBI claims don’t usually raise rates, you may see an increase if you lose a claims-free discount.

Is mechanical breakdown insurance worth it?
MBI may be worth it for some drivers, but whether it’s right for you will depend on your specific needs, budget, and preferences. For some, the added peace of mind is worth the cost. Others prefer to save that money in a rainy day fund to cover the cost of unexpected car repairs.
A few things to consider when deciding if MBI is worth it to you include:
The average repair cost for your vehicle
Your budget and savings
The cost difference between an extended warranty and MBI
