Always insist on GM Collision Parts for your collision repair to restore your vehicle's safety, comfort, and performance. Don’t settle for imitation collision parts for your auto body repair that may not measure up in design, materials, fit, assembly, or comparative testing. GM Collision Parts are the Original Equipment Manufacturer parts for your vehicle, so you know you're getting GM quality, reliability, and durability.

To find out more about GM Collision Parts, see the Certified Service experts at your local Chevy, Buick, GMC, or Cadillac auto body repair shop.


Genuine GM Collision Parts are new parts made with the same materials and construction methods as the parts with which your vehicle was originally built. Genuine GM Collision Parts are the best choice for your auto body repair to ensure that your vehicle's designed appearance, durability, and safety are preserved. The use of Genuine GM Parts can help maintain the GM New Vehicle Limited Warranty.

It’s your vehicle. You can choose Genuine GM Parts and be confident that the repairs have been made using manufacturer-recommended parts. Don’t settle for alternatives such as recycled parts to repair your vehicle. These are not Genuine GM Collision Parts. While, in most cases, the parts are from undamaged sections of the vehicle, the origin and history of these parts are unknown. Such parts are not covered by the GM New Vehicle Limited Warranty, and any related failures are not covered by that warranty. Why take chances with your collision repair? With Genuine GM Parts installed by the Certified Service experts, you can rest assured you’re getting the best quality collision and auto body repair available for your vehicle.

Aftermarket collision parts may also be suggested to repair your GM vehicle. These parts are made by companies other than GM and may not have been tested for the vehicle. As a result, these parts may fit poorly, exhibit premature durability/corrosion problems, and may not perform properly in subsequent collisions. Aftermarket parts are not covered by the GM New Vehicle Limited Warranty, and any vehicle failure related to such parts is not covered by that warranty.



It is your right to have your vehicle restored to pre-crash condition. That means insisting on original replacement parts from your vehicle’s manufacturer. Many insurance policies limit compensation for collision repair through the use of aftermarket collision parts. These aftermarket parts do not provide the same level of original fit, form, and function as GM Collision Parts. Check your insurance policy now for Original Equipment Manufacturer parts usage. If genuine parts are not specified, request a policy that states only GM Original Equipment Manufacturer parts will be used to repair your vehicle.

If another party's insurance company is paying for the auto body repair, you are not obligated to accept a repair valuation based on that insurance company's collision policy repair limits, as you have no contractual limits with that company. In such cases, you have control of the repair and parts choices, so insist on Genuine GM Parts.

Remember, you have a choice. You can either choose genuine parts made by the original manufacturer, or you can choose imitations of those parts made by other companies. Not only can these imitations compromise your vehicle’s safety performance in subsequent collisions, they may also diminish your vehicle’s resale value down the road. When you have the damage repaired at your local GM auto body center using only Genuine GM Parts, you get the peace of mind of proper equipment and quality replacement parts. When it comes to collision repair and auto body repair, it just makes good sense to turn to the GM-trained Certified Service experts.

Why Genuine GM Air-Bag System Parts After a Crash?
Collision repair and auto body repair professionals should always use extreme caution when performing repairs to a vehicle’s Supplemental Restraint System (SRS), which includes air bags. GM Original Equipment does not support the use of any used, salvaged, or imitation parts for SRS collision repair. Only new, genuine GM-warranted parts should be used in repair because of the critical nature in the design of air-bag systems.

General Tips

1. If your vehicle cannot be driven, know where the towing service will be taking it. Get a card from the tow truck operator or write down the driver’s name, the service’s name, and phone number.

2. Choose a reputable collision repair facility for your vehicle. Whether you select a Chevrolet, Buick, GMC, or Cadillac dealer, or a private collision repair facility to fix the damage, make sure you’re comfortable with your choice.

3. Remove any valuables from your vehicle before it’s towed away. Make sure this includes your insurance information and registration if you keep these items in your vehicle.

4. If possible, call your insurance company from the scene of the accident. They’ll walk you through the information they’ll need. If they ask for a police report, don’t worry. Just call or go to the police department’s headquarters and you can get a copy of the report.

5. You’ll need to gather the following important information from the other driver:

  • Driver’s name, address, and telephone number
  • Driver’s license number
  • Owner name, address, and telephone number
  • Vehicle license plate number
  • Vehicle make, model, and model year
  • Vehicle Identification Number (VIN)
  • Insurance company and policy number
  • General description of the damage to the other vehicle

6. If you have a question about your estimate, don’t be afraid to ask for an explanation. Reputable shops welcome this opportunity. The only way to make sure you get Genuine GM Parts is to ask for them yourself. Ask your insurance agent and collision repair facility representative if your vehicle will be repaired with Genuine GM Parts. If the answer is yes, then you’ll be getting the value, safety, endurance, and peace of mind you expect. If they say imitation parts might be used, you have the right to refuse them. It’s your choice.
