Insurance covers some repairs but not all — it depends on your policy type and what caused the damage

Car insurance does not cover routine maintenance or wear-and-tear repairs. It covers damage from specific events — collisions, theft, weather, vandalism — but only if you have the right coverage type for that event. A fender bender is covered under collision insurance. A tree falling on your car is covered under comprehensive insurance. An engine that simply fails is not covered under either, because it is not damage from an external event.

The distinction matters because you pay for different coverage separately. Liability insurance (required in every state) pays for damage you cause to someone else's car or property — it does not pay for your own repairs. Collision and comprehensive are optional add-ons that protect your own vehicle. If you have a loan or lease, your lender will require you to carry both. If you own the car outright, you choose whether the cost is worth it.

Key Takeaways

  • Collision insurance covers repairs from accidents you cause or are involved in, minus your deductible.
  • Comprehensive insurance covers theft, weather, vandalism, and animal strikes, minus your deductible.
  • Liability insurance covers damage you cause to other people's property, not your own repairs.
  • Maintenance repairs — oil changes, brake pads, worn belts — are never covered by any car insurance policy.
  • Your deductible is what you pay out of pocket; the insurance company pays the rest up to your policy limit.

What collision insurance covers

Collision insurance pays for repairs when your car hits another vehicle, a fixed object, or rolls over. It covers accidents you cause, accidents someone else causes, and single-vehicle accidents where you hit a guardrail or tree. The insurance company pays for the repair minus your deductible — typically $500 or $1,000, though you can choose a lower or higher amount when you buy the policy.

Collision does not cover the other driver's repairs if you are at fault. That is what your liability insurance does. Collision only covers your own vehicle. If the repair cost is less than your deductible, you pay the full amount yourself and do not file a claim — there is no point, because the insurance company will not pay anything.

If your car is financed or leased, your lender requires collision coverage. If you own it outright, you decide whether to carry it. The decision usually comes down to the car's value: if repair costs would strain your budget, collision makes sense. If the car is worth less than a few thousand dollars, the monthly premium may cost more than you would save.

What comprehensive insurance covers

Comprehensive insurance covers damage to your car from events other than collisions. This includes theft, vandalism, weather (hail, flooding, wind), falling objects, and animal strikes. If a deer hits your car, comprehensive pays. If a tree branch falls on your roof, comprehensive pays. If someone breaks your window or slashes your tires, comprehensive pays. If your car is stolen, comprehensive pays the actual cash value of the vehicle.

Like collision, comprehensive has a deductible you pay first. The insurance company then covers the rest, up to the actual cash value of your car. If your car is worth $8,000 and comprehensive damage costs $6,000, the insurance company pays $6,000 minus your deductible. If damage costs $12,000 but your car is only worth $8,000, the insurance company pays $8,000 minus your deductible, and the car is declared a total loss.

Comprehensive is also optional if you own your car outright, but required if you have a loan or lease. It is usually cheaper than collision because weather and theft happen less often than accidents. In areas with frequent hail, flooding, or theft, comprehensive premiums are higher.

What is never covered: maintenance and wear

No car insurance policy covers routine maintenance or parts that wear out over time. Oil changes, tire rotations, brake pad replacement, battery replacement, transmission fluid flushes, and engine coolant refills are your responsibility. Neither are repairs for parts that fail because of age or use: a transmission that stops working, an alternator that dies, a water pump that leaks.

Insurance also does not cover damage you cause by neglecting maintenance. If you never change your oil and your engine seizes, that is not covered. If you ignore a warning light and the engine fails, that is not covered. The insurance company will deny the claim because the damage resulted from lack of maintenance, not from a covered event.

Some dealerships and independent shops offer extended warranties or service plans that cover certain repairs after the manufacturer's warranty ends. These are separate from insurance and work differently — you pay a set fee upfront and the plan covers named repairs. They are not insurance products.

How deductibles work and when they apply

Your deductible is the amount you pay toward a repair before insurance kicks in. If you have a $500 deductible and collision damage costs $2,000, you pay $500 and the insurance company pays $1,500. If damage costs $300, you pay the full $300 and do not file a claim, because the insurance company would pay nothing.

You choose your deductible when you buy or renew your policy. A higher deductible ($1,000 or $1,500) lowers your monthly premium. A lower deductible ($250 or $500) raises your monthly premium. The trade-off is between what you pay monthly and what you pay when you file a claim. If you rarely drive or have a strong emergency fund, a higher deductible saves money over time. If you drive frequently or cannot afford a large out-of-pocket cost, a lower deductible makes sense.

Deductibles apply separately to collision and comprehensive. You might have a $500 collision deductible and a $250 comprehensive deductible. If you file a collision claim, you pay $500. If you file a comprehensive claim, you pay $250. If you file both in the same year, you pay both deductibles.

When your insurance company might deny a repair claim

Insurance companies deny claims for several reasons. The most common is that the damage is not covered under your policy — for example, filing a comprehensive claim when you only have liability and collision. Another is that the damage resulted from a cause not covered by your policy, such as normal wear or lack of maintenance.

Claims are also denied if you did not disclose information when you bought the policy. If you said you use your car for personal driving only but actually use it for rideshare, the company may deny a claim. If you said you have a clean driving record but did not mention a recent accident, the company may deny a claim. The insurer can also deny a claim if you do not cooperate with their investigation — for example, refusing to provide photos or a police report.

If your claim is denied, you have the right to appeal. Read the denial letter carefully to understand the reason. If you believe the denial is wrong, contact your insurance company's appeals department and provide additional information. You can also file a complaint with your state's insurance commissioner if you believe the company acted unfairly.

Liability insurance and repairs to other people's cars

Liability insurance covers damage you cause to someone else's vehicle or property. If you hit another car and are found at fault, your liability insurance pays for their repairs (up to your policy limit) and any injuries you caused. It does not pay for your own repairs — that is what your collision insurance does.

Liability has two parts: bodily injury liability, which covers medical bills and lost wages for people you injure, and property damage liability, which covers damage to vehicles and property. Every state sets a minimum liability limit you must carry. Most states require at least $25,000 in property damage liability, but this varies. Your policy limit is the maximum the insurance company will pay for one accident.

If you cause an accident and the other driver's repairs exceed your liability limit, you may be sued for the difference. This is why many people carry higher limits than the state minimum — it provides more protection if you cause a serious accident.

Frequently Asked Questions

Does insurance cover engine problems or transmission failure?

No. Engine and transmission failures are considered mechanical wear, not damage from a covered event. Insurance covers damage from collisions, theft, weather, and vandalism — not parts that fail because of age or use. If the failure resulted from an accident (for example, the engine seized after you drove through deep water), collision or comprehensive might cover it, depending on the cause.

Will insurance pay if I hit a pothole and damage my suspension?

Collision insurance may cover suspension damage from hitting a pothole, but only if you can prove the impact caused the damage. Many insurance companies deny these claims because they consider potholes a normal road hazard. Your best option is to document the pothole with photos and file a claim with your city or county — they may reimburse you if the pothole was unusually deep or unmarked.

What happens if I do not have collision or comprehensive insurance?

If you do not have collision or comprehensive and your car is damaged, you pay for repairs yourself. If someone else causes the accident, their liability insurance should pay, but only if they have it and only up to their policy limit. If you have a loan or lease, your lender requires both collision and comprehensive, so this situation does not apply unless you own the car outright.

Can I file a claim for damage I caused myself?

Yes, if the damage is covered by your policy. If you back into a pole and have collision insurance, you can file a claim. You will pay your deductible and the insurance company pays the rest. If you only have liability, you cannot file a claim for your own damage — liability only covers damage you cause to other people's property.

Does my insurance cover rental car repairs while mine is being fixed?

Not automatically. Some policies include rental reimbursement coverage, which pays for a rental car while yours is in the shop after a covered accident. This is an optional add-on you choose when you buy your policy. If you do not have it, you pay for a rental yourself. Check your policy documents or call your insurance company to see if rental reimbursement is included.
