Filing a warranty claim sounds straightforward — but the process has landmines. A single misstep (authorizing repairs before calling, using an unapproved shop, losing a receipt) can turn a covered claim into a denied one. This guide walks you through every step correctly, so you don't give your warranty company a reason to reject what should be a routine reimbursement.
This guide applies to extended warranties and vehicle service contracts (VSCs). If you have a manufacturer factory warranty, the process is similar but handled through the dealership service department. For details on factory warranty appeals, see our appeals guide.
Step 1: Assess the Situation Safely
Don't keep driving a vehicle that may cause further damage
If your check engine light is on, you're hearing unusual noises, or the vehicle is overheating — pull over safely and stop driving. Continuing to operate a vehicle with an active mechanical failure can turn a covered $800 repair into a $4,000 engine replacement that the warranty company argues was caused by operator negligence.
Document everything at the moment it happens:
- Current odometer reading (photograph the dashboard)
- Date and time of the event
- Exact symptoms — sounds, warning lights, behavior changes
- Recent driving conditions (highway, short trips, towing)
This documentation forms the foundation of your claim. The more specific you are now, the stronger your position if the claim is disputed later.
Step 2: Call Your Warranty Company First
Pre-authorization is required by most contracts — skip this and you risk losing coverage
Before authorizing any repairs, call the claims number on your warranty contract. Most vehicle service contracts require pre-authorization — repairs started without approval are one of the most common grounds for administrative denial, even on otherwise covered failures.
Have this information ready when you call:
- Your contract or policy number
- Vehicle year, make, model, and VIN
- Current mileage
- Description of symptoms and when they started
- Location of the vehicle
Get the name of the representative you speak with, the date and time, and a confirmation or reference number. Write all of this down — it becomes part of your claim record.
Step 3: Choose an Approved Repair Facility
Using an unapproved shop is one of the easiest ways to have a claim rejected
Most vehicle service contracts require repairs to be performed at an ASE-certified repair facility or licensed repair shop. Some contracts have preferred networks. Check your contract's repair facility section before dropping the vehicle off anywhere.
Priority Auto Protection accepts any ASE-certified repair facility nationwide — you're not locked into a dealer network. But for other providers, verify before you commit to a shop.
When selecting a shop:
- Confirm they have experience with VSC/extended warranty claims
- Verify they can contact your warranty administrator directly
- Ask if they charge a diagnostic fee — and whether that's covered
- Confirm they'll provide a written diagnosis before any repairs begin
Step 4: Get a Written Diagnosis
The mechanic's written diagnosis is your claim's spine — it must be specific
The repair shop will diagnose the vehicle and prepare a repair order listing the failed component, the failure cause, and the recommended repair. This document is submitted to the warranty administrator with the claim.
A strong diagnosis for warranty purposes should include:
- The specific failed component (not just "engine issue" — the exact part)
- The failure mode (not "bad" — "bearing seized due to metal-on-metal contact")
- Confirmation that the failure is not due to maintenance neglect, modification, or misuse
- The mechanic's name, ASE certification number, and shop letterhead
If the written diagnosis is vague, ask the shop to be more specific. Vague diagnoses give warranty administrators room to deny.
Step 5: Wait for Authorization
Do not authorize repairs until the warranty company approves the claim
Once the shop submits the claim with the diagnosis and repair estimate, the warranty administrator reviews it. Most straightforward claims are authorized within 24–48 business hours. More complex claims — or those requiring physical inspection — can take 3–7 business days.
During the authorization window:
- Ask the shop to provide a rental car recommendation if your contract includes rental coverage
- Stay in contact with both the shop and the warranty company
- If the warranty company requests an inspection, cooperate fully
- Do not authorize additional unrelated repairs that could complicate the claim
Step 6: Approve Repairs and Pay Your Deductible
Once authorized, the warranty company pays the shop directly — you pay only your deductible
When the claim is approved, the warranty administrator will authorize a specific dollar amount for the repair. The shop proceeds with the repair and submits the completed invoice to the warranty company. The warranty company pays the shop directly for the covered amount. You pay your deductible ($0, $100, or $200 depending on your contract).
Before authorizing the repair, confirm:
- The authorized amount covers the full repair cost
- Any gap between the authorized amount and actual cost (if applicable)
- Your deductible amount — confirm it matches your contract
- The repair warranty (most shops warrant their labor for 12 months / 12,000 miles)
Step 7: Keep All Records After the Repair
The claim isn't over when the car is fixed — your records protect future claims
Keep copies of every document related to the claim:
- The original repair order and diagnosis
- The warranty authorization confirmation
- The final invoice showing what was paid by the warranty company vs. your deductible
- Your communication log from every contact with the warranty administrator
These records matter for two reasons: (1) future claims on the same system may reference this repair, and (2) if your warranty company attempts a retroactive denial, you need documentation that the claim was properly authorized and paid.

Common Mistakes That Kill Warranty Claims
- Starting repairs before calling The most common and fatal mistake. Always call the warranty company before authorizing any work. Repairs begun without pre-authorization are denied on procedural grounds even when the failure is covered.
- Using an unapproved shop Using a shop that isn't ASE-certified or isn't on the approved network gives the provider grounds for an administrative denial regardless of the actual failure.
- No maintenance records Filing a claim without being able to produce maintenance records for the failed component's service interval. Gaps in your service history are the most common supporting argument for denial.
- Vague mechanic's diagnosis A repair order that says "engine noise" instead of "main bearing failure due to oil starvation — independent of maintenance history" gives the warranty administrator a reason to push back or inspect.
- Not keeping a communication log Failing to document who you spoke to, when, and what was said. If the claim is denied and you escalate to regulatory agencies, this log is your evidence.
- Repairing it yourself first DIY repairs before filing a claim give the warranty company cover to deny on the grounds that they can't independently verify the original failure mode. Always get a professional diagnosis before any work is done.
If Your Claim Gets Denied
A denial is not the end of the road. Most warranty denials can be appealed — and a significant percentage are overturned when the right documentation is presented. Your immediate steps:
- Request the denial in writing with the specific contract clause cited
- Read our guide to the top 10 denial reasons to understand the specific argument being made against your claim
- Follow the full appeals guide for step-by-step instructions
- Use the documentation checklist to ensure your appeal package is complete
- If the appeal fails, escalate via the complaint filing guide
