How to Use OEM Repair Procedures to Fight Insurance Claim Denials
Why OEM Procedures Matter
Insurance companies frequently deny or underpay claims by arguing that cheaper, non-OEM repair methods are "equivalent." This is often wrong — and dangerous. OEM (Original Equipment Manufacturer) repair procedures exist because the manufacturer engineered specific methods, materials, and sequences to maintain the vehicle's structural integrity, safety systems, and warranty coverage.
What Are OEM Repair Procedures?
OEM repair procedures are the manufacturer's official instructions for repairing their vehicles after a collision. They include:
- Joining methods: Specific welding types, rivet specifications, and adhesive requirements
- Materials: Steel grades, aluminum alloys, and composite specifications
- Safety precautions: High-voltage disconnect procedures for EVs, airbag handling, UHSS restrictions
- Tooling requirements: Specialized equipment like 3D measuring systems, STRSW guns, rivet tools
- Prohibited practices: Actions the manufacturer explicitly forbids (e.g., heat straightening UHSS steel)
How to Use OEM Procedures Against Insurers
1. Pull the OEM Procedure Before Starting Work
Access the manufacturer's repair portal and download the specific procedures for the vehicle and damage area. Major portals:
- Tesla: Tesla Body Repair Manual (available to certified shops)
- BMW: BMW TIS (Technical Information System)
- Toyota/Lexus: Toyota TIS
- Honda/Acura: Honda Service Express
- GM: GM Genuine Parts Collision
2. Include OEM Procedures in Your Estimate
Attach the relevant OEM procedure pages to your estimate. When an insurer sees documented manufacturer requirements, it's much harder for them to argue for shortcuts.
3. Cite Specific Position Statements
Most manufacturers publish position statements on topics like:
- Aftermarket parts: Many OEMs explicitly state that aftermarket parts void their warranty
- Scanning: Pre- and post-repair scanning is required by most OEMs on 2016+ vehicles
- ADAS recalibration: Required after any front-end, windshield, or sensor-adjacent work
- Aluminum repair: Dedicated tools and facilities required — no cross-contamination with steel
4. Reference I-CAR Standards
I-CAR (Inter-Industry Conference on Auto Collision Repair) publishes Uniform Procedures that are recognized industry-wide. When the OEM procedure isn't available, I-CAR standards are the next best authority.
Common Insurance Objections and Responses
| Insurer Says | You Respond |
|---|---|
| "We don't pay for pre/post scan" | "The manufacturer requires it. Failure to scan could miss safety-critical DTCs." |
| "Use aftermarket parts" | "The OEM position statement prohibits aftermarket parts for this application. Using them voids the manufacturer's warranty." |
| "That labor time is too high" | "These are the OEM-published repair times. Deviating from them risks an improper repair." |
| "ADAS recalibration isn't necessary" | "The manufacturer requires recalibration after any work in this area. Skipping it could cause the system to malfunction." |
Key Takeaway
The OEM procedure is your strongest weapon against insurer shortcuts. When you can point to a published manufacturer requirement, the insurer's argument shifts from "we don't want to pay for it" to "we're asking you to violate the manufacturer's instructions" — which is a much harder position for them to defend, especially if a lawsuit results from an improper repair.
