Documentation is the difference between a claim that gets paid and one that gets denied. Warranty companies look for gaps in your paperwork — a missing oil change receipt, a vague mechanic's diagnosis, or no record of your pre-authorization call are all they need to push back on an otherwise valid claim.
Use this interactive checklist before filing your claim, during the process, and if you need to file an appeal. Check items off as you gather them. Everything marked REQUIRED must be in hand before proceeding.
Section 1: Contract & Policy Documents
📋 Contract & Policy
0 / 4
Warranty contract or VSC agreement REQUIREDYour full contract document — either printed copy or PDF. Contains coverage terms, exclusions, and claims procedures. If lost, contact your provider for a duplicate.
Policy/contract number REQUIREDRequired to open any claim. Found on the first page of your contract, welcome letter, or any prior billing statement.
Coverage start and end dates REQUIREDConfirms your coverage was active at the time of the failure. Verify the failure date falls within the coverage period and after any waiting period.
Deductible amount and claims number REQUIREDThe 24-hour claims phone number (usually on your contract's front page or wallet card). Know your deductible before the shop asks.
Section 2: Vehicle Records
🚗 Vehicle Records
0 / 4
Vehicle Identification Number (VIN) REQUIREDFound on the driver's side dashboard (visible through windshield), driver's door jamb sticker, and your vehicle registration. Needed for every claim.
Current odometer reading (photographed) REQUIREDPhotograph the dashboard showing the odometer at the time of the failure. Timestamp the photo. Mileage disputes are a common denial reason — this evidence prevents them.
Vehicle registration OPTIONALConfirms ownership and vehicle information. Some providers request this to verify the named insured matches the vehicle registration.
Prior vehicle history report (CARFAX / AutoCheck) OPTIONALA clean vehicle history report at enrollment is strong evidence against pre-existing condition denials. Pull a current report and compare it to your enrollment documentation.
Section 3: Maintenance Records
This section is where most claims are won or lost. Providers look for gaps in maintenance records to argue the failure resulted from neglect. Gather every document you can find for the service interval covering the failed component.
🔧 Maintenance Records
0 / 6
Oil change records (all locations) REQUIRED for engine claimsDealership invoices, quick-lube receipts, or credit card statements showing service charges. Retrieve from every shop you've used — most retain records 5–7 years.
Transmission fluid service records REQUIRED for transmission claimsTransmission fluid change or inspection records per manufacturer intervals. Usually every 30,000–60,000 miles depending on vehicle and driving conditions.
Coolant flush / cooling system records REQUIRED for cooling system claimsEvidence of coolant maintenance. Overheating events that aren't in your records can be used to argue inadequate cooling system maintenance caused other failures.
Dealership electronic service history RECOMMENDEDMost dealerships maintain digital service records by VIN. Call the dealer and request a full service history printout — this often recovers records from services you no longer have receipts for.
Credit card / bank statements showing service charges OPTIONALIf physical receipts are missing, bank or credit card statements showing charges at automotive service locations can help establish a service history even without itemized receipts.
Prior repair invoices on the same system RECOMMENDEDAny prior invoices for related components. If the same system was repaired before and covered, this demonstrates the failure was mechanical, not due to neglect.
Section 4: Failure Documentation
📸 Failure Documentation
0 / 4
Photos of dashboard warning lights REQUIREDPhotograph all illuminated warning lights immediately when symptoms appear. Check engine, oil pressure, transmission temp, ABS — each light tells a specific story. Timestamp the photos.
Video of symptom if intermittent HIGHLY RECOMMENDEDFor noises, rough running, or intermittent failures, video evidence is more persuasive than any written description. Film the symptom before it's repaired — it's impossible to recreate afterward.
Photos of visible damage or leak RECOMMENDEDFluid leaks, damaged components, worn parts — photograph before any cleaning or repair. These photos counter any argument that the failure was gradual or pre-existing.
OBD-II diagnostic trouble codes (DTCs) RECOMMENDEDIf you have access to an OBD-II scanner, record the fault codes before the shop clears them. These codes are the electronic record of what the car's computer detected and are difficult to dispute.

Section 5: Shop & Repair Documents
🏪 Shop & Repair Documents
0 / 5
Written mechanic's diagnosis on shop letterhead REQUIREDMust include: shop name and ASE certification, mechanic's name and number, specific failed component, failure mode (not just "bad" — the exact failure mechanism), and confirmation of mileage at time of diagnosis.
Repair estimate with part numbers REQUIREDItemized estimate showing labor hours, parts costs, and part numbers. The warranty company authorizes specific amounts based on this estimate — vague estimates lead to partial or denied authorizations.
Shop's claim submission confirmation REQUIREDConfirmation that the shop submitted the claim to the warranty administrator — including the date submitted, the authorization request number, and the name of the administrator contact.
Authorization confirmation from warranty company REQUIREDWritten or emailed confirmation of claim approval — including authorization number, authorized repair amount, and any conditions. Never proceed without this.
Final repair invoice REQUIREDCompleted repair invoice showing work performed, parts installed (with part numbers), total cost, amount paid by warranty company, and your deductible paid. Keep this permanently.
Section 6: Communication Log
Every contact with your warranty company should be logged. If your claim is denied and you escalate to the BBB, state attorney general, or small claims court, this log is your evidence. Providers know consumers don't keep logs — when you produce one, it demonstrates professionalism and changes the negotiating dynamic.
📞 Communication Log
0 / 3
Pre-authorization call documented REQUIREDDate, time, representative name, phone number called, confirmation number received. This is the most critical entry in your log — proof you called before authorizing repairs.
All subsequent contacts logged REQUIREDEvery follow-up call, email, or chat — what you asked, what was promised, by whom. Providers sometimes give inconsistent information; your log is the record of what was actually said.
Any written correspondence saved REQUIREDAll emails, letters, and denial letters from the warranty company. Print emails and save to a folder. Do not delete any correspondence — even "routine" updates may become relevant in an appeal.
Section 7: Appeal Documents (if claim was denied)
⚖️ Appeal Documents
0 / 4
Denial letter with specific clause cited REQUIREDThe denial must be in writing and cite the specific contract clause. Verbal denials aren't sufficient. If you only received a verbal denial, write a letter requesting written documentation immediately.
Mechanic's rebuttal statement REQUIRED for technical disputesIf denied on technical grounds (pre-existing, wear-and-tear, maintenance), get a written statement from your mechanic specifically rebutting the denial reason. Must be on shop letterhead with mechanic's credentials.
Independent inspection report RECOMMENDED for high-value denialsFor claims over $1,000, an independent ASE-certified inspection ($150–$300) that contradicts the warranty company's denial reason is often worth the cost. Objective third-party evidence carries significant weight in appeals and regulatory complaints.
Formal written appeal letter REQUIREDSent certified mail with return receipt. Must cite the specific denial reason, the contract clauses supporting your claim, and request reversal within a stated timeframe. See our full appeals guide for a template.

💡 Pro Tip: Always repeat back what the representative told you before ending the call — "So just to confirm, you're saying my claim has been approved for $1,200 and the authorization number is 48821?" This locks in their statement and creates a clear record of what was promised.
