What is mechanical breakdown insurance coverage?

Mechanical breakdown insurance (MBI) is an optional add-on that helps cover costly repairs for major mechanical failures unrelated to accidents, unlike standard auto insurance (which won’t cover a failing transmission or broken A/C) MBI steps in for these big-ticket repairs. It works similarly to an extended warranty, protecting essential parts such as the engine, brakes, and powertrain.

MBI isn’t included in a typical policy, but it can be a great addition for certain drivers. For instance:

  • Drivers with a newer vehicle
  • Those planning to keep their cars long-term
  • Those who want more predictable expenses
  • Owners of vehicles with complex tech

Is car repair insurance the same as mechanical breakdown insurance?

There’s no single policy called “car repair insurance." This could technically mean any coverage that helps pay for vehicle repairs.

Mechanical breakdown insurance (MBI) is one option, along with traditional collision and comprehensive coverage (usually called full coverage), which covers damage from accidents and other external events. However, collision and comprehensive don’t cover mechanical failures, like drivetrain issues, while MBI does.

What does mechanical breakdown insurance cover?

Mechanical breakdown insurance covers vehicular damage occurring outside of a car collision. Much like comprehensive or collision coverage, MBI is subject to variable deductibles. For mechanical breakdown insurance to provide coverage, the value of repair costs needs to be greater than the policy's deductible. Mechanical breakdown deductibles are usually $250.


Typically, the following parts can be covered by MBI:

  • Engine
  • Transmission
  • Exhaust
  • Air conditioning
  • Technical components, computer

Covered repairs are outlined in your policy, so check with your insurer to see what’s included or if additional protection can be added.

Does insurance cover a blown engine?

Unfortunately, a blown engine can be an expensive fix, and typical car insurance won't cover it (unless it's caused by a covered accident and you have full coverage). But if you have mechanical breakdown insurance, it can be really helpful if you blow an engine, a transmission fails, or your A/C goes out. 

The key factor is maintenance—if you’ve kept up with regular service and your engine still fails due to a covered event, your insurance may help foot the bill.


How much does mechanical breakdown insurance cost?

MBI can cost around $100 a year, but the price varies depending on your provider and car (its make, model, mileage, etc.). So, if you have an electric car, you’ll pay a different rate than someone with a Toyota Corolla or a Ferrari. But remember that MBI often comes with a high deductible, which means the policyholder (you!) may end up paying out-of-pocket for many expenses. 

The cost of MBI varies by insurer and vehicle, but it is typically more affordable than extended warranties offered by dealerships. For instance, GEICO's MBI charges a small premium per policy period instead of a large lump-sum payment upfront.


Mechanical breakdown insurance vs. extended warranty

A typical warranty on a new car lasts about three years. An extended warranty does just what it says— it takes that three-year warranty and makes it last as long as you choose to pay for it. Here are a few key differences between an extended warranty and MBI through an insurer. 

MBI

  • You can choose your repair facility
  • Added to your regular insurance payment
  • Not offered by all insurance companies

Extended warranty

  • You have to use an approved repair shop
  • Usually paid via a bigger lump sum
  • Offered my many third-party companies

Agent insight: Can anyone buy MBI?

"Generally, companies will let you purchase additional coverage to protect your assets fully. However, MBI may have some limitations. For example, GEICO's MBI coverage specifies that vehicles must have 15,000 miles or fewer and be newer than 15 months old. The owner must also be the first person to own the car.[1] This definitely reduces the number of people who can purchase and benefit from MBI. Still, third-party companies (who aren't insurers) may have different options for vehicle service contracts (VSCs)."

Which companies offer mechanical breakdown insurance?

Not all insurance companies offer Mechanical Breakdown Insurance (MBI) because it’s costly, less in demand, and faces tough competition. Big repairs, such as engine or transmission failures, can be expensive for insurers to cover, making MBI a risky option for some. Plus, many new cars already come with manufacturer warranties, so drivers may not need extra coverage right away. On top of that, dealerships and third-party companies dominate the extended warranty market, so traditional insurers are less likely to offer MBI as part of their policies.

GEICO mechanical breakdown coverage

GEICO is one of the biggest providers of mechanical breakdown insurance. GEICO's mechanical breakdown coverage is for new or leased vehicles with less than 15,000 miles, purchased within the past 15 months. Once you have this coverage, it may remain active for up to seven years or 100,000 miles.

Below are the damages covered and not covered by GEICO’s mechanical breakdown insurance.


Covered damage:
  • Cooling systems
  • Suspension
  • Steering
  • Transmission
  • Drive axle engine
Not covered:
  • Regular maintenance services such as changing brake pads, spark plugs, air filters, tires, or tune-ups, suspension alignment, and wheel balancing.
  • Any damage that is intentionally caused or caused by misuse
GEICO mechanical breakdown cost:

The cost of MBI will depend on the value of your vehicle. As such, GEICO does not advertise standard mechanical breakdown coverage costs. Although independent sources claim GEICO's coverage is expensive, GEICO states its MBI costs “pennies per day.”

USAA mechanical breakdown insurance

Managed and serviced by Assurant Solutions, USAA’s option for MBI is called Extended Vehicle Protection. While less specific about its coverage option than GEICO, USAA’s MBI program applies to the failure of a covered fault under normal and usage of the vehicle. There are three main qualifications your vehicle must meet:

  • The vehicle needs to be younger than 10 years old
  • Less than 250,000 miles
  • Be covered under its original dealership warranty

Although they do not specifically state what is and is not covered, Assurant and USAA program offers additional coverage such as roadside assistance, car rental services, and overnight expenses. This is in addition to their mechanical breakdown coverage options.

Once your vehicle’s original dealership warranty expires, you will no longer be eligible for USAA’s MBI coverage. Because it is managed by Assurant rather than USAA, you will be dealing with their customer service and claims team. Assurant does not state how much this coverage will cost.

Is mechanical breakdown insurance worth it?

It can be worthwhile for drivers who want added protection from unexpected repair costs and who meet certain conditions. It’s most useful for drivers who:

  • Own a new or near-new vehicle that qualifies for MBI
  • Plan to keep the car long-term, especially after the factory warranty expires
  • Would struggle to cover a major repair out of pocket
  • Drive a vehicle with complex or expensive components, such as hybrids or advanced electronics
  • Prefer predictable expenses and want to reduce financial uncertainty around repair

FAQs

MBI usually costs about $100 per year, but it depends on your rating factors and vehicle. Ask your insurance company if they offer MBI, and if there are discounts you may qualify for by adding it to your policy.

Your insurance could pay for an engine replacement if it fails due to a covered peril (such as a collision). Car insurance covers unexpected accidents, not age or wear and tear. Typically, engine failure is due to maintenance and wear and tear, or possible manufacturer defects (which would likely be covered through a warranty or recall initiative).

Mechanical breakdown insurance (MBI) helps pay for unexpected car repairs that aren’t caused by accidents or normal wear and tear. It typically covers major parts like the engine, transmission, electrical system, and steering. After you pay your deductible, your provider covers the rest of the repair cost.

MBI won’t cover things like oil changes, brake pads, or tires—those are considered regular maintenance. Coverage details vary, so check your policy to see what’s included.

MBI can be great for specific drivers. For instance, if you've got a new car, and plan to keep your vehicle for a long time, you would have trouble covering repair costs, or like to have relatively predictable expenses. If you've got a car with a lot of extra features or tech components, it's also a good idea to carry MBI.

Yes, but there are limitations: the car must be 15 months old or less, have fewer than 15,000 miles, and the person buying the policy must be the first owner. If you meet the requirements to get MBI through GEICO, you can extend it for up to 100,000 or 7 years (whichever comes first).[1]
