After a car accident, most people expect their vehicle to be repaired with the same quality parts it originally had. Those original parts, known as OEM parts, are designed by the vehicle’s manufacturer. They match the car’s safety standards, design, and long-term performance. When repairs begin, many drivers assume the insurance company will use these parts without question.

However, there are some cases where the insurer uses aftermarket parts for a vehicle. These parts are made by third-party companies, not the original manufacturer. Some insurance companies prefer using them because they cost less. This choice can raise concerns about safety, value, and how well the repaired car will perform. Knowing what to do next helps drivers protect both their vehicle and their rights.

Understand the Difference Between OEM and Aftermarket Parts

OEM parts come directly from the car’s manufacturer. They fit perfectly and match the design of the original components. Many drivers feel safer choosing OEM parts because they come from the same company that built the car.

Aftermarket parts are made by outside manufacturers. They may not match the exact design or quality of the original part. Some work well, while others do not. The difference in quality can affect safety, appearance, and long-term performance.

Understanding this difference helps drivers know why the insurance company made its choice and what steps to take next.

Review Your Insurance Policy

The first step is to check your insurance policy. Some policies allow the insurance company to use aftermarket parts. Others require OEM parts for certain repairs. The policy may also use terms like “like kind and quality,” which can mean different things depending on the situation.

Drivers should look for sections that explain parts replacement and repair standards. If something is unclear, they should ask the insurance company to explain it. Knowing what the policy says helps drivers understand their options.

Request an Explanation from the Insurance Company

Drivers have the right to ask why the insurance company chose aftermarket parts. They can request a written explanation. This helps show whether the decision follows the policy or if it is simply a cost-saving choice.

The explanation may include:

• Price differences

• Availability of OEM parts

• Repair timelines

• Compatibility claims

A clear explanation helps the driver prepare for the next steps.

Talk With the Auto Body Shop

The repair shop can be a helpful source of information. Technicians can explain how the aftermarket part compares to the OEM part. They can also share any concerns about safety, fit, or long-term durability.

Drivers should ask the technician:

• Will the aftermarket part fit properly?

• Does it affect safety features?

• Does it change the appearance of the car?

• Is the part certified?

If the technician believes the part is not suitable, that opinion can support a request for OEM parts.

Document Your Concerns

Drivers should keep records of all conversations, emails, and repair estimates. These documents help show why the aftermarket part may not be the right choice. They also help if the driver needs to challenge the insurance company’s decision.

Documentation may include:

• Photos of damage

• Written opinions from technicians

• Copies of estimates and reports

• Communication with the insurance adjuster

The more organized the information, the stronger the case becomes.

Ask for OEM Parts When Needed

Drivers can request OEM parts if they believe aftermarket parts will not properly repair the car. Some states have rules that allow this request under certain circumstances. Drivers can also point out safety concerns, resale value issues, or warranty questions.

If the insurance company refuses, drivers can ask for the refusal in writing. This helps when seeking further review.

Consider Filing a Complaint

If a driver believes the insurance company is not acting fairly, they can file a complaint with their state’s insurance department. These departments oversee insurance practices and review disputes.

Filing a complaint does not guarantee immediate results, but it helps ensure the insurance company follows state rules.

Think About Getting Outside Support

In some cases, drivers may need outside help. This can include a second opinion from another repair shop or guidance from someone familiar with auto claims. Expert support can make the process easier and help clarify what parts are best for the repair.
