Can I Request OEM Parts for My Auto Insurance Claim? A Complete Guide

Quick Answer

If you've been in a collision, you can ask your insurer to use original equipment manufacturer (OEM) parts for repairs, but approval depends on your policy, state laws, and the insurer's assessment of cost versus value. This guide explains the rules, how to make a strong request, and what to expect during the claims process.

What Are OEM Parts?

OEM parts are components made by the vehicle's original manufacturer or an approved subcontractor, matching the exact specifications, fit, and finish of the part originally installed on your car. They differ from aftermarket parts, which are produced by third‑party companies and may vary in quality, design, or warranty.

Why OEM Parts Matter in a Claim

Choosing OEM parts can affect:

• Vehicle value: OEM parts help preserve resale value and maintain the manufacturer's warranty.
• Fit and function: They are designed to work seamlessly with your vehicle's systems.
• Safety: Certain safety‑critical components (airbags, brake calipers) are often required to be OEM.

Insurance Policies and OEM Parts

Most standard auto policies do not explicitly guarantee OEM parts. Instead, they use language such as "reasonable and customary" repair costs. Whether OEM parts are covered depends on three key factors:

• Policy language: Some policies include an "OEM endorsement" that guarantees OEM replacement for a higher premium.
• State regulations: A few states (e.g., Michigan, New York) have statutes that give consumers the right to request OEM parts.
• Claim value: For high‑value or luxury vehicles, insurers are more likely to approve OEM parts to avoid depreciation.

Step‑by‑Step: How to Request OEM Parts

1. Review Your Policy

Locate the section on "parts and equipment." Look for terms like "OEM," "original equipment," or "manufacturer‑specified parts." If you're unsure, call your agent and ask directly.

2. Document the Damage

Get a detailed estimate from a reputable body shop that specifies OEM parts. Include part numbers, manufacturer names, and cost breakdowns.

3. Submit a Formal Request

Write a concise letter to the adjuster stating:

• Your desire for OEM parts
• Why they are necessary (e.g., safety, warranty, vehicle value)
• Supporting estimate and any relevant policy language

Send the request via certified mail or the insurer's online portal for a paper trail.

4. Negotiate if Needed

If the insurer offers aftermarket parts, you can:

• Request a cost‑plus quote (OEM cost plus a reasonable markup)
• Offer to cover a portion of the price difference
• Escalate to a supervisor or the state insurance department

5. Appeal the Decision

Should the claim be denied, you have the right to appeal. Provide additional evidence such as:

• Manufacturer's recommendation for OEM replacement
• Expert testimony from a certified mechanic

File the appeal within the timeframe specified in your policy (usually 30‑45 days).

When OEM Parts Are Typically Required

Insurers are more likely to approve OEM parts in the following scenarios:

• Luxury or high‑performance vehicles where aftermarket parts could affect performance
• Safety‑critical components (airbags, seat belt pretensioners, steering knuckles)
• Vehicles still under manufacturer warranty

Cost Considerations

OEM parts often cost 15‑30% more than comparable aftermarket options. However, the long‑term value may offset the premium. Below is a typical cost comparison:

State‑Specific Rules

Some states have consumer‑friendly statutes:

• Michigan: No‑fault law allows drivers to request OEM parts if the vehicle is less than five years old.
• New York: Insurance regulators require insurers to provide OEM parts when the vehicle's market value exceeds $25,000, unless the policy expressly limits it.
• California: No specific OEM mandate, but the Department of Insurance encourages transparent cost breakdowns.

Common Misconceptions

My insurer will always use the cheapest part. Not always. Adjusters balance cost with depreciation, vehicle age, and policy language.

OEM parts are always better. While OEM ensures exact fit, high‑quality aftermarket parts can be comparable and cost‑effective for older, lower‑value cars.

Final Checklist Before Filing

• Confirm policy language regarding OEM parts.
• Gather OEM‑specific estimates from a reputable shop.
• Document vehicle age, mileage, and warranty status.
• Know your state's OEM regulations.
• Prepare a written request with supporting evidence.

By following these steps, you increase the likelihood that your insurer will honor a request for OEM parts, protecting both your vehicle's integrity and its resale value.
