Why it matters
- Safety systems and sensors: Cameras, radar, and sensors in windshields, bumpers, and grilles depend on precise specifications to work correctly.
- Structure: High-strength steels, aluminum, and crash-energy structures must perform as engineered to protect you in the next accident.
Manufacturer requirements vary
Each automaker sets its own requirements. Some recommend OEM parts in general and require new OEM parts for safety-critical and structural components. Others restrict alternative parts further, including on vehicles with driver-assistance systems. We follow the requirements for your vehicle.
When your insurance is involved
Your insurance policy may influence which part types appear on an estimate. We review the estimate with your insurer's adjuster and with you. If an estimate conflicts with the manufacturer's procedures or position statements, we'll tell you, and you can choose to pay the difference to use OEM parts.
When an estimate includes aftermarket parts, we always look for certified options, and we check each part for fit and quality before it goes on your vehicle.
Customer-paid repairs
If you're paying for the repair yourself and choose not to use OEM parts, any non-OEM part we use must be a certified aftermarket part.
Your choice and a clear estimate
- You can request OEM parts at any time and pay the difference.
- Every estimate lists the type of each part, so you know what is going on your vehicle.
- Parts carry the applicable manufacturer's warranty. See our Limited Lifetime Warranty page for details.
Review our parts form before you visit
Before repairs begin, you'll review and sign our Replacement Parts Disclosure and Customer Authorization Form. It explains each part type (new OEM, aftermarket, salvage, and remanufactured) and shows which types will be used on your repair.
