Does Car Insurance Cover Mechanical Repairs?

Last Updated on February 5, 2026

Car insurance is great at covering sudden, accidental damage—like crashes, theft, hail, or vandalism. But if your car needs a repair because something simply wore out or failed over time, standard auto insurance usually won’t pay the bill.

Standard car insurance usually doesn’t cover mechanical repairs caused by wear and tear, aging parts, or routine breakdowns.
Insurance may pay for repairs when the damage is caused by a covered event (like a collision, theft, hail, or vandalism) rather than an internal failure.
For mechanical failures, drivers typically need a warranty/service contract or optional Mechanical Breakdown Insurance (MBI), which is often limited to newer vehicles.
Before paying out of pocket, review your policy and document what happened—some “mechanical” damage may still be claim-related if it followed a covered incident.

Quick Answer: Car Insurance Usually Doesn’t Cover Mechanical Repairs

In most cases, an ordinary auto policy won’t cover mechanical repairs caused by wear and tear, age, or a part failing on its own. However, you may get coverage when the repair is tied to a covered claim (like a collision or comprehensive loss), or if you buy separate protection like mechanical breakdown insurance or a warranty.

When Car Insurance Can Pay for Repairs

Standard auto insurance is designed for accidents and unexpected events—not breakdowns. That said, you can see repairs covered when they’re the direct result of a covered incident, such as:

Crash damage covered by collision coverage (for example, impact damage to your suspension or radiator after hitting an object)
Non-collision damage covered by comprehensive coverage (sometimes called “other than collision”)—often discussed in “full coverage” conversations (see full coverage vs. comprehensive coverage)
Damage you cause to others covered by liability insurance (this pays for the other person’s repairs and injuries—not your own car’s mechanical problems)

Bottom line: if the mechanical repair is needed because of a covered event, insurance might pay. If the repair is needed because the vehicle is aging or a part failed on its own, insurance usually won’t.

What Car Insurance Typically Won’t Cover

Most policies exclude mechanical issues tied to regular maintenance and gradual breakdown. That includes many of the most expensive “my car won’t run” repairs.

Common examples of repairs that are usually out-of-pocket

Brake pad replacement and other wear-item replacements
Oil changes, fluids, filters, and tune-up-type maintenance
A blown engine or internal engine failure not tied to a covered incident
Big-ticket mechanical failures like transmission repairs
Component repairs like suspension work, axle replacement, or piston repairs

If you’re dealing with a breakdown and you’re unsure whether anything is covered, start by confirming what your policy says and what caused the damage—see Am I covered if my car breaks down?

Alternatives That Can Cover Mechanical Repairs

If you want coverage for mechanical failures, you typically need something outside a standard auto policy—usually a warranty or a specialty add-on.

1) Manufacturer warranty or extended warranty

New cars often come with factory warranty protection, and you may be able to purchase extra coverage. Here’s a deeper look at what a car warranty covers.

2) Mechanical Breakdown Insurance (MBI)

Mechanical breakdown insurance (MBI) is optional coverage that’s designed specifically to pay for certain unexpected mechanical repairs—often for newer vehicles. It’s sometimes called “car repair insurance,” and it’s offered by select insurers (for example, see GEICO and Progressive).

MBI rules vary by company and state, but it commonly comes with:

Vehicle eligibility requirements (often limited to newer vehicles, which is why it’s frequently discussed alongside coverage options for new cars)
A deductible you pay when you use the coverage (learn how deductibles work here: car insurance deductibles explained)
Covered vs. excluded parts lists (maintenance and wear items are still typically excluded)

Compared to a dealer warranty, MBI is often billed like insurance (monthly or with your premium) instead of a big up-front purchase.

Is Mechanical Breakdown Insurance Worth It?

MBI can be worthwhile if (1) your vehicle qualifies, (2) you want predictable costs, and (3) a major repair would strain your budget. Like any add-on, it can raise your premium—so it helps to understand why your insurance might be high even with no accidents before adding more coverage.

A quick checklist to help you decide

How long you’ll keep the car: MBI is usually most appealing if you plan to keep the car well past the factory warranty period.
Your emergency fund: If you can comfortably pay a sudden $2,000–$5,000 repair, you may not need MBI.
Your risk tolerance: If you’d rather pay a little extra each month to reduce surprise bills, MBI can make sense.
Coverage details: Compare exclusions, the deductible, and where repairs can be done (dealer vs. any licensed shop).

If You Think a Repair Might Be Covered, Here’s What to Do

If the issue happened after a covered event (like a crash, vandalism, flood, or falling object), don’t assume it’s “just mechanical.” Take photos, save towing/repair paperwork, and contact your insurer. This step-by-step guide explains how to go through your insurance company to get repairs done.

FAQs on Car Insurance and Mechanical Repairs

Does comprehensive insurance cover mechanical failure?

Usually, no. Comprehensive coverage is meant for non-collision events like theft, vandalism, hail, fire, or falling objects. If a part fails due to age or wear (like an alternator, water pump, or transmission), that’s typically not covered unless the failure was directly caused by a covered comprehensive event.

Will car insurance cover engine or transmission repairs?

In most cases, insurance won’t cover an engine or transmission repair if it failed on its own. However, if the engine/transmission was damaged in a covered accident or another covered loss (like flood damage), the related repairs may be covered under collision or comprehensive, minus your deductible.

If a mechanical part breaks and causes a crash, is the repair covered?

It depends on what needs fixing. Collision coverage may pay for accident damage to your vehicle from the crash, but it generally won’t pay to replace the worn or defective part that failed first. For example, collision might cover body damage from the wreck, but not the underlying worn component that triggered it.

Is Mechanical Breakdown Insurance (MBI) the same as an extended warranty?

They’re similar because both can help pay for unexpected repairs, but they’re not identical. MBI is offered by insurers as an optional coverage add-on, often billed with your insurance. Extended warranties (service contracts) are typically sold by manufacturers, dealers, or third-party providers and may be paid up front or financed.

What cars qualify for mechanical breakdown insurance?

Eligibility is set by the insurer and commonly depends on the vehicle’s age and mileage. Many companies restrict MBI to newer or lower-mileage vehicles, and availability can vary by state. If you’re interested, check your insurer’s requirements before assuming your car qualifies.

How much does MBI cost, and what deductible should I expect?

Costs vary based on the insurer, vehicle, and coverage terms. Many MBI policies use a deductible in the “few hundred dollars” range, but the exact amount depends on the plan you choose. Always compare the premium increase, deductible, and exclusions to see if it’s a good value for your situation.

How do I file a claim if I think the repair is covered by insurance?

Start by documenting what happened and why you believe it’s tied to a covered event (photos, police report if applicable, receipts, towing invoice, and the shop’s written diagnosis). Then contact your insurer before authorizing major work. Your adjuster may need to inspect the vehicle or approve the estimate first.

Final Word on Car Insurance and Mechanical Repairs

Standard auto insurance is built to cover accidental damage and sudden losses—not the cost of keeping a vehicle running. So if your car needs mechanical repairs due to age, wear, or breakdown, you’ll usually pay out of pocket.

If you want protection for unexpected mechanical failures, look into warranty options or mechanical breakdown insurance (if your car qualifies). And at renewal time, it’s smart to compare your coverages and costs—here’s why it matters to review your car insurance policy regularly.
