Repair coverage that’s an insurance policy.
Mechanical breakdown insurance for newer cars, set next to the extended warranty a dealer offers, so you can compare coverage, exclusions and price.

Same protection, different rules
Your auto policy doesn’t pay for a car that breaks down. The California Department of Insurance says comprehensive coverage does not cover mechanical breakdown, normal wear and tear or maintenance. Repair coverage comes in three forms: a vehicle service contract from a service contract provider, a service contract where the dealer is the obligor, and mechanical breakdown insurance. The first two are what dealers usually call an extended warranty. MBI is an insurance policy, so the insurance company is the one that owes you.
That difference matters. In California, the Department of Insurance regulates the price of MBI so it isn’t excessive, and MBI can only be sold by licensed insurance companies and agents; the price of a service contract isn’t regulated and can be negotiated like the car. Which cars qualify for MBI is up to each insurance company, and it’s commonly limited to newer cars with low mileage, so the time to ask is soon after you buy. I check whether your car qualifies and lay MBI next to any dealer contract, coverage against coverage.
- MBIAn insurance policy; the insurance company pays claims, and in California its price is regulated.
- Service contractA repair agreement with a provider or dealer, sold as an extended warranty.
- Factory warrantyComes with the car. A breakdown it covers isn’t paid by MBI or a service contract.
- Your auto policyComprehensive and collision don’t cover breakdown, wear and tear or maintenance.
What underwriters will ask
Having these ready means I can go to market on the first call. The quote form asks for the same things, and anything you don’t know yet can wait.
- The car: year, make, model, VIN and current odometer reading.
- Purchase: date you bought or leased it, and whether you’re the first owner.
- Factory warranty: the bumper-to-bumper and powertrain terms that still apply.
- Dealer offer: any service contract you were offered, with its price and terms.
- Current policy: your auto declarations page.
- Use: commuting, pleasure, or any rideshare or delivery driving.
What California law calls each one
Insurance Code section 116 says an agreement to repair or replace a car or any part of it after a mechanical or electrical breakdown, at no cost or reduced cost to you, is automobile insurance. It then carves out vehicle service contracts governed by Part 8 of Division 2, which begins at section 12800.
Section 12800 defines a vehicle service contract as an agreement, for a separately stated price and a specific duration, to repair, replace or maintain a vehicle after an operational or structural failure caused by a defect in materials or workmanship, or by normal wear and tear. The same section also counts tire and wheel, glass, paintless dent and key or fob agreements as service contracts. For cars, the "seller" is a dealer or lessor-retailer that sells the contract incidental to its business of selling or leasing vehicles.
The California Department of Insurance guide spells out what follows:
- Breakdown insurance may legally be sold over the internet. Service contracts are sold through car dealers; the department says providers selling directly by phone or online in California commit a felony.
- Repair delays or poor-quality work at a shop, including a dealer's own shop, go to the Bureau of Automotive Repair. Delays by the company paying the claim go to the backup insurer first, then the department.
Other states vary. My side-by-side comparison walks through the paperwork.
Cancelling a service contract: the refund rules
California Civil Code section 1794.41 sets the cancellation rules for vehicle service contracts sold for use in the state. Each starts with written notice to the person the contract names:
- Full refund window. Cancel within the first 60 days after you receive the contract, with no claims made, and the seller refunds the full amount paid. For a used car without manufacturer warranties, the window is 30 days. The contract may allow longer.
- Claim made inside the window. You get a pro rata refund instead, based on elapsed time or a measure of use such as mileage or the retail value of service performed. On a vehicle contract, the obligor picks the method at the time you cancel.
- After the window. You still get a pro rata refund. The seller may also keep a cancellation or administrative fee of no more than 10 percent of the contract price or $25, whichever is less.
- Financed contracts. The refund may be made payable to you, the assignee or the lender of record, or both.
You must be able to inspect the contract before buying; it or a brochure covering its terms and cancellation rules is due at or before purchase, and the contract itself within 60 days after. Where Part 8 of the Insurance Code conflicts with this section, Part 8 controls.
For a breakdown policy, get its cancellation clause in writing before you buy. Other states set their own rules.
Federal rules and electric cars
The FTC says a service contract is not a warranty under federal law, because you buy it separately. Its guide to the Magnuson-Moss Warranty Act adds:
- The Act does not require any business to give a written warranty.
- A seller that makes a service contract on its own product cannot disclaim or limit implied warranties. A seller that only sells another company's contract as its agent, with no written warranty of its own, can.
- A warranty generally cannot require a particular brand of parts or service to stay in force, unless those are provided free under the warranty or the FTC grants a waiver.
The FTC's consumer guide adds that you don't have to use the dealer for repairs or maintenance to keep a factory warranty in effect. Aftermarket or recycled parts don't void it either. If such a part causes damage to a covered part, the manufacturer or dealer can deny that repair, but it must prove the part caused the damage.
For electric cars, the Department of Energy's Alternative Fuels Data Center says many manufacturers offer 8-year/100,000-mile warranties on the battery, and that replacing one outside the warranty is expected to be a significant expense. Some battery systems use liquid coolant that may need regular checks. Compare your battery warranty's end date with any repair agreement's start date.
Mechanical breakdown insurance, answered
What’s the difference between MBI and an extended warranty?
Protection can look the same; the rules differ. New York’s insurance regulator has described mechanical breakdown coverage as essentially the same kind of protection as a service contract, regulated as insurance instead. In California, MBI prices are regulated by the Department of Insurance and service contract prices are not.
Which cars qualify for MBI?
Each insurance company sets its own eligibility, commonly based on the car’s age and mileage, and many only write it on newer cars. Ask soon after you buy. Price also depends on the miles on the odometer when coverage starts.
What does MBI usually exclude?
Read the exclusions section. Repair agreements often won’t pay for breakdowns caused by skipped maintenance, overheating, wrong or contaminated fluids, alterations, towing too much weight, pre-existing damage, or negligence. Some exclude wear and tear, and commercial use is often excluded unless you bought that coverage.
Does MBI pay while my factory warranty is still in effect?
No. The California Department of Insurance notes that a breakdown covered by a manufacturer’s new car warranty won’t be covered by a service contract or MBI. Compare the dates before you buy, so you aren’t paying for overlap.
What records do I need to keep?
Proof of routine maintenance. A claim can be denied if you can’t show a part that needed maintenance was maintained, and the FTC notes that skipping the manufacturer’s schedule might void a service contract. Keep receipts and a log with dates and mileage.
Do you offer mechanical breakdown insurance outside California?
Yes. Clients across the country send the same quote form. Sam Alishahi is licensed in all 50 states and Washington, DC and places policies there directly. The shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
