Common car warranty exclusions

New vehicles typically include a manufacturer warranty (bumper-to-bumper and powertrain limits vary by brand). Extended or third-party service contracts are separate products—sold at dealerships, online, or by phone—with their own administrators, deductibles, and exclusions.

The Federal Trade Commission (FTC) advises reading the full contract before buying, not the sales brochure. Neither factory nor extended coverage pays for everything.

Most contracts distinguish mechanical failure from normal wear. Commonly excluded wear items include:

• Brake pads, rotors, and drums
• Clutch components on manual transmissions
• Wiper blades, belts, and hoses (unless tied to a covered failure—often disputed)
• 12V batteries (hybrid/EV high-voltage systems may have separate rules)
• Tires, filters, fluids, and routine maintenance supplies

Unless your plan explicitly includes wear-and-tear coverage—uncommon on budget tiers—repairs attributed to normal use may be denied.

Contracts almost always require proof of proper maintenance. Missing records can void otherwise covered claims.

• Missed oil changes or incorrect fluid specifications
• Ignored recalls or manufacturer technical service bulletins
• Driving with known warning lights or unfixed problems
• Non-OEM modifications not approved by the contract
• Commercial use (rideshare, delivery) when the plan is rated for personal use

Keep dated receipts and follow the schedule in your owner’s manual. Documentation gaps are a top denial reason cited in consumer complaints.

Many plans impose waiting periods (often 30–90 days) and mileage caps before coverage starts. Problems that existed before enrollment—or that appear during the wait—are excluded.

Some administrators require an inspection at signup. Undisclosed issues discovered later can limit coverage for related components.

Damage from events outside normal operation is typically excluded:

• Collision, vandalism, and theft (auto insurance territory)
• Flood, fire, lightning, or rodent damage
• Contaminated fuel or wrong fluids
• Overheating from ignored coolant leaks or continued driving after warnings
• Off-road use or racing if prohibited by the contract

Service contracts focus on mechanical breakdown, not appearance:

• Paint, body panels, rust, and glass (unless a separate rider applies)
• Interior trim, upholstery, and squeaks or rattles
• Infotainment and navigation (sometimes partial coverage on premium tiers only)
• A/C refrigerant top-offs versus compressor failure—terms differ

Exclusionary (comprehensive-style) contracts cover mechanical parts except those listed as excluded—broader and usually pricier.

Stated-component contracts cover only named systems. Anything not listed is excluded by default. Cheap plans may cover major assemblies but exclude seals, gaskets, and diagnostic labor.

Read the Definitions section. Phrases like “internally lubricated parts” have precise contractual meanings.

Even covered parts may not be paid if:

• Repairs start without administrator pre-approval
• You use a shop outside the required network
• Labor rates exceed plan caps
• Diagnosis fees are non-reimbursable
• Annual or lifetime payout limits are exhausted

The FTC recommends confirming who backs the contract (dealer, manufacturer, or independent administrator) and researching complaint history before you pay.

1. Is this exclusionary or stated-component coverage?
2. What is the deductible per visit—and per component?
3. Are there per-claim or lifetime caps?
4. Can I use any licensed repair facility?
5. What maintenance records are required, and how far back?
6. What happens if the administrator becomes insolvent?
7. What are cancellation and refund terms?

Get answers in writing. Verbal promises from sales staff may not bind the claims administrator.
