Can I require the at-fault driver's insurance company to repair my recently purchased car with appropriate replacement parts instead of substandard parts?

What Can You Require From the Insurer and Repair Shop?

Your property-damage claim is legally against the driver who caused the collision. That driver’s insurance company usually investigates the claim, approves a repair estimate, and pays covered amounts on the driver’s behalf. An insurer’s estimate does not necessarily settle every disagreement about the proper repair.

The goal of a third-party property-damage claim is generally to address the loss caused by the collision. A reasonable repair should correct crash-related damage and restore the vehicle as closely as reasonably possible to its condition before the collision. That does not automatically mean every damaged component must be replaced with a new original equipment manufacturer, or OEM, part.

Several types of parts may appear on an estimate:

• OEM parts are supplied through the vehicle manufacturer’s system.
• Aftermarket parts are new parts made by another company.
• Recycled or salvaged parts come from another vehicle.
• Reconditioned, rebuilt, or repaired parts have previously been used or restored.

A label alone does not establish whether a part is appropriate. The important questions include whether it fits correctly, functions as intended, complies with applicable repair procedures, affects a warranty, and returns the vehicle to a reasonably comparable condition.

North Carolina’s Rules About Replacement-Part Disclosure

North Carolina’s Motor Vehicle Repair Act provides useful protections in disputes with repair shops. When the Act applies, under N.C. Gen. Stat. § 20-354.8, a repair shop may not substitute used, rebuilt, salvaged, or straightened parts for new replacement parts without notifying the vehicle owner and, when applicable, the insurer paying for the repairs.

This notice rule does not say that an insurer must approve OEM parts in every case. It does mean you should be able to determine what type of parts the shop plans to install. Ask for a line-by-line estimate identifying each part as OEM, aftermarket, recycled, rebuilt, reconditioned, or repaired.

You may also request a detailed final invoice showing the parts actually installed. If the work has not been completed, ask the shop in writing to explain any differences between the insurer’s estimate, the shop’s repair plan, and the manufacturer’s published procedures for your vehicle’s model and year.

How to Challenge a Part or an Inadequate Repair

A specific, documented objection is usually more useful than describing all non-OEM parts as substandard. For each disputed item, identify the actual concern. Examples may include poor panel fit, mismatched materials, warning lights, missing calibration work, visible finish problems, a shorter part warranty, or a written manufacturer procedure calling for a different repair method.

Consider taking these steps:

1. Request the complete estimate. Obtain every page, including part numbers, labor operations, scans, measurements, calibrations, paint procedures, and supplements.
2. Ask the shop to identify each disputed part. Request the manufacturer, source, condition, warranty, and part number in writing.
3. Request a written explanation. Ask the adjuster why the proposed part is considered reasonably comparable and whether the decision accounts for the vehicle manufacturer’s repair instructions.
4. Obtain another written repair assessment. A second qualified repair facility may identify incomplete operations, fit problems, hidden damage, or manufacturer procedures missing from the first estimate.
5. Document the vehicle before further work. Photograph panel gaps, paint differences, damaged components, dashboard warnings, and other visible concerns. Keep the original photos as well as dated follow-up photos.
6. Ask about a supplement. Repair shops commonly submit supplemental estimates when teardown reveals hidden damage or when additional procedures become necessary.
7. Review paperwork before signing. Determine whether a document authorizes repairs, accepts the vehicle as complete, releases a property-damage claim, or resolves all collision-related claims.

If you believe the vehicle may not be safe to drive, avoid making your own technical determination. Arrange for the condition to be assessed by a qualified repair facility and keep the written findings.

Repair Quality and Diminished Value Are Different Issues

An inadequate repair and diminished value are related but separate concerns. Corrective work may be needed if collision damage was not properly repaired. Diminished value concerns whether the vehicle is worth less after the collision and repairs than it was immediately before the crash.

In North Carolina, property loss is generally measured by the difference between the vehicle’s fair market value immediately before and immediately after the damage. Repair estimates and invoices can help show that difference, but the repair bill is not always the complete measure of the loss. A recently purchased vehicle may still carry a market penalty because of its collision history even when its repairs appear satisfactory.

Useful diminished-value evidence can include the purchase agreement, pre-crash mileage, maintenance history, photographs, the complete repair file, comparable vehicle information, and a written valuation that accounts for the collision history. Learn more about documents that may support a diminished-value claim for a newer vehicle.

What About Missed Work and Inconvenience?

Time spent making calls, visiting the shop, or dealing with an adjuster is understandably frustrating, but inconvenience by itself is not automatically a separate category of recoverable property damage. A claim for lost income requires reliable proof that income was actually lost and that the loss was legally caused by the collision or repair process. Save work schedules, leave records, wage statements, and written communications showing why time away from work was required.

Loss of use may be more directly relevant. When a repairable vehicle is unavailable for a reasonable repair period, the reasonable cost of a comparable rental vehicle may be evidence of the loss. Keep rental records, transportation receipts, repair dates, delay explanations, and messages about when the vehicle was available for pickup.

How This Applies to the Recently Purchased Vehicle

Here, the other insurer has approved repairs after its driver reportedly passed on the shoulder and struck the side of the vehicle. The citation and crash report may help document what happened, but they should be preserved with photographs, witness information, and insurer communications rather than treated as the only evidence of fault.

Because no physical injuries were reported, the immediate dispute is primarily a property-damage matter. The most useful next step is to identify precisely which parts and repair operations are disputed. The vehicle owner should obtain the insurer’s estimate, the shop’s work order, all supplements, part numbers, invoices, warranties, and any written explanation of the repair procedures used.

If the vehicle has already been returned, document each problem promptly and request a written inspection before corrective work erases evidence of the original repair. If the repair is completed but the collision history still reduces the car’s market value, a separate diminished-value claim may be considered. This guide explains proof that may show lost value even when repairs look complete.

Preserve These Records

• The purchase agreement, financing documents, and pre-crash vehicle listing.
• The crash report, citation information, scene photographs, and witness details.
• Every insurer estimate, repair-shop estimate, supplement, work order, and final invoice.
• Part numbers, packaging labels, warranties, and written descriptions of the parts used.
• Photographs from before repairs, during teardown if available, and after completion.
• Emails, text messages, claim letters, and notes of conversations with the adjuster and shop.
• Rental records, transportation receipts, repair timelines, and proof of any claimed wage loss.
• Any valuation report or written assessment of incomplete or improper repairs.

Many North Carolina property-damage claims are subject to a three-year filing period under N.C. Gen. Stat. § 1-52. The exact deadline depends on the claim, and negotiations with an insurer do not automatically extend the time to file a lawsuit.
