Can I Decide Which Parts Are Used On My Car After an Accident?
If you are dealing with a collision repair, one of the first questions many car owners ask is, can I decide which parts are used on my car? It is a fair question and an important one. The parts installed during a repair affect safety, performance, appearance, and long term value. Your car is more than transportation, it is an investment, and you deserve clarity and control during the repair process. At Re-Lux Collision, we believe informed car owners make better decisions. Below is a complete, detailed guide to help you understand your options, your rights, and how to ensure the right part is chosen for your vehicle.
One useful tip when buying parts is to use your vehicle identification number (VIN number) to cross reference parts and verify compatibility. This helps avoid ordering the wrong part and ensures the replacement matches your vehicle’s specifications exactly. You can use online catalogs and websites such as Rock Auto, which offer extensive vehicle-specific parts databases for brands like Jeep, BMW, and many others. These platforms allow you to search by your vehicle’s make, model, and engine size to find the correct components, including common parts like spark plugs.
Why Choosing the Right Car Parts Matters More Than Most Drivers Realize
Parts affect safety, performance, and vehicle value
Every car is built as a system. Each component works with the rest to protect you and deliver proper performance. When the wrong part is installed, that system can be compromised. Using the correct OEM replacement helps maintain factory safety standards, protects resale value, and ensures the car performs the way it was designed to.
Modern vehicles are more complex than ever
Today’s vehicle includes advanced systems, electronics, and engineered tolerances. The engine, transmission, sensors, and accessories all depend on precise components. A windshield is no longer just glass, it supports cameras and safety systems. A bumper supports sensors and energy absorption. Choosing the correct OEM part matters more now than ever.
The wrong part can cause long term issues
A wrong part may physically fit but still create problems. Poor alignment, warning lights, premature wear, or system failures are common when parts do not match the vehicle’s specifications. This leads to frustration, added cost, and future repairs that could have been avoided.
The Main Types of Parts Used in Collision Repair
OEM parts
OEM stands for original equipment manufacturer. OEM parts are designed by the manufacturer to match your vehicle’s specifications exactly. Correct OEM components are built for your make and model, engine size, and system requirements. These parts are engineered to integrate seamlessly with the rest of the vehicle.
Aftermarket parts
Aftermarket parts are produced by third party companies. Some aftermarket components meet quality standards, while others do not. Fit and finish can vary, and aftermarket parts may not always match OEM specifications. Insurance companies may suggest aftermarket options because of price differences.
Used auto parts and recycled parts
A used auto part is an original OEM component taken from another vehicle. When properly inspected, a used auto part can be a cost effective option for certain common parts such as doors, hoods, or wheels. Quality depends on condition, mileage, and compatibility.
Remanufactured parts
Remanufactured components are restored used parts, often engine parts, radiators, or accessories. These parts must meet strict quality standards to be reliable. Proper testing and correct part number matching are essential.
Can You Legally Choose Which Parts Are Used on Your Car?
The short answer
Yes, you can decide which parts are used on your car. Car owners have the right to ask what auto parts are being installed and to discuss alternatives. You can request OEM, aftermarket, or used auto part options before authorizing repairs.
The longer answer
Insurance policies often control payment, not choice. You can request a specific part, but insurance may only cover what they consider equivalent replacement. If you want correct OEM parts and your policy does not include OEM coverage, you may be responsible for the price difference.
What this means for vehicle owners
Transparency matters. You should always see a detailed estimate listing part numbers, component descriptions, and whether the part is OEM, aftermarket, or used. Reviewing this information allows you to make informed decisions and avoid surprises.
Will Insurance Pay for the Parts You Want?
When OEM parts are typically covered
OEM replacement is often approved for newer vehicles, safety related components, or when manufacturer repair procedures require correct OEM installation. Some policies include OEM endorsements that cover original parts automatically.
When insurance may limit coverage
Older cars or standard policies may default to aftermarket or used auto part replacement. This does not mean OEM is unavailable, it means insurance may not pay the full amount.
Paying the difference
Many car owners choose to upgrade parts by paying the difference. A reputable shop will explain pricing clearly, document the process, and ensure you receive the right part without pressure.
Why OEM Repair Procedures Often Decide the Right Part
Manufacturer procedures guide repairs
Manufacturers publish detailed repair procedures for every system on a vehicle. These procedures specify correct components, tools, and methods. Ignoring these instructions can compromise safety and system performance.
ADAS and modern systems
Advanced driver systems depend on exact positioning and calibration. The correct OEM bumper, windshield, or bracket ensures sensors function properly. Installing the wrong part can disrupt the entire system.
Professional standards matter
A professional mechanic with proper training uses specialized tools and follows manufacturer specifications. This approach protects your car and ensures the repair meets industry standards.
What a Quality Collision Repair Shop Should Do for You
Explain your options clearly
A trusted shop explains OEM, aftermarket, and used auto part options in plain language. You should understand how each choice affects quality, price, and long term reliability.
Advocate during the process
A quality shop communicates with insurance, provides documentation, and supports correct repairs. They help connect the dots between manufacturer procedures and approved parts.
Full transparency
Every part should be listed with a part number, description, and source. Nothing should be installed without your authorization. This protects your vehicle and your peace of mind.
