Do I have to accept aftermarket parts in my collision repair?

No. In Nevada you have the right to choose your repair facility and to request OEM or OEM-equivalent parts. Your insurance estimate may be written with aftermarket parts as a cost-control measure, but you can negotiate this with your insurer. Your repair shop can assist by documenting why OEM parts are appropriate for your vehicle and repair.

Are all aftermarket collision parts poor quality?

Not all aftermarket parts are low quality. CAPA-certified aftermarket parts have been independently tested for fit and material quality. However, quality varies significantly across the aftermarket supply chain, and not all parts carry certification. For structural components and safety-system mounting points, OEM or certified aftermarket parts are the appropriate standard.

How do repair procedures affect safety after a collision?

Manufacturer repair procedures specify how structural sections should be repaired, where welds should be placed, and how safety systems should be restored. Deviating from these procedures can change how the vehicle structure absorbs and distributes energy in a future collision, potentially reducing the protection the vehicle was designed to provide.

What is I-CAR and why does it matter for repair quality?

I-CAR (Inter-Industry Conference on Auto Collision Repair) is an industry organization that develops and delivers collision repair training and establishes professional development standards for technicians and shops. I-CAR Gold Class is the highest shop-level designation and requires ongoing training to maintain - it indicates that technicians are trained on current repair procedures for modern vehicle platforms.

Why OEM-Style Repairs Matter After a Collision

After a collision, the decisions made about how your vehicle is repaired - which parts are used, which procedures are followed, which standards are applied - affect the outcome in ways that are not always visible at pickup. OEM-style repairs use parts and procedures that meet or match the original manufacturer specifications for your vehicle. Understanding what that means, and why it matters, helps Las Vegas drivers ask the right questions and make informed decisions about their repair.

What OEM Means in Auto Body Repair

OEM stands for original equipment manufacturer. In the context of auto body repair, OEM parts are components manufactured by or to the specifications of the vehicle's original manufacturer. An OEM fender for a Honda Accord, for example, is made to the same specifications as the fender that came on the vehicle when it was built - same dimensions, same material properties, same mounting points, same paint adhesion characteristics.

OEM-style repairs use OEM or equivalent-quality parts combined with repair procedures that follow the vehicle manufacturer's published repair guidelines. These guidelines specify how structural sections should be sectioned, which components can be repaired versus replaced, what welding procedures apply, and how safety systems should be handled. Following them produces a repair that matches factory intent as closely as possible.

The Alternative: Aftermarket Parts

Aftermarket collision parts are manufactured by third parties to approximate OEM dimensions and fit. Quality varies significantly across the aftermarket parts market. Some aftermarket parts from reputable suppliers with CAPA (Certified Automotive Parts Association) certification perform comparably to OEM. Others are poorly fitting, use lower-quality materials, or require significant adjustment during installation to achieve proper panel gaps and alignment.

Panel fit: aftermarket panels sometimes require more adjustment to achieve even gaps and flush alignment with adjacent panels
Paint adhesion: material differences in some aftermarket parts can affect how primer and paint adhere
Structural components: aftermarket structural parts may not match the energy absorption and deformation characteristics engineered into OEM components
Sensor mounting: aftermarket parts may not position sensors, cameras, and lighting electronics to the same tolerances as OEM components

Why Structural Repair Procedures Matter

The parts used in a repair matter - but the procedures used to install them matter just as much. Vehicle manufacturers publish detailed repair procedures that specify how each section of the vehicle should be repaired or replaced. These procedures address weld types and locations, section cut points for partial replacement, adhesive specifications, corrosion protection requirements, and ADAS calibration steps.

A shop that does not follow manufacturer repair procedures may produce a repair that looks correct from the outside but does not perform correctly in a future collision. Structural sections welded incorrectly or cut at the wrong locations change how energy is absorbed and distributed through the vehicle structure in a crash. This is not a cosmetic concern - it is a safety concern.

OEM Repairs and Your Vehicle Warranty

For vehicles still under manufacturer warranty, the repair procedures used in a collision repair can affect whether warranty claims related to the repaired area are honored. Repairs that deviate significantly from manufacturer guidelines may give a manufacturer grounds to decline warranty claims for related components. This is a practical reason - in addition to the safety and quality reasons - to insist on OEM-standard repair procedures for newer vehicles.

Your Right to Choose Repair Standards in Nevada

In Nevada, you have the right to choose your own repair facility and to specify the repair standards you want applied to your vehicle. Your insurance carrier may write an estimate based on aftermarket parts, but you can request that OEM or OEM-equivalent parts be used. The difference in cost, if any, may be negotiable with your insurer depending on your policy terms and vehicle age. Your repair shop can assist with this conversation.
