Counterfeit Parts

Have A Counterfeit Part?

We do everything in our power to ensure you are purchasing legitimate GM Genuine Parts and ACDelco parts.

Counterfeits Part Are:

  • Not made in accordance with GM standards, which can lead to premature part failure, system breakdowns, or even vehicle safety events.
  • Packaged and designed to intentionally mislead you, often duplicating known trademarks exactly or ever so slightly, in the hope that you, the consumer, won’t notice the slight differences.

Why Should I Care?

  • Counterfeit parts cast a shadow on GM Genuine Parts’ reputation of providing high-quality replacement parts. Counterfeit parts may not meet the same standards as the genuine parts, which can lead to mechanical problems and system breakdowns, or even cause safety concerns.
  • Imitation parts typically don’t last as long as legitimate GM Genuine Parts and ACDelco parts, making it necessary to replace them more frequently.
Avoid Counterfeit Parts by Always Purchasing from a GM Dealer or GM Genuine Parts Reseller

How to Spot

Here are tips to help identify a counterfeit part:

  • INSPECT THE PACKAGING. Always ask an installer if you can view the part packaging prior to installation. If it appears flimsy, lacks the name brand or logo, or has a name that is similar to, but not the same as, those you’re used to seeing (such as GM Genuine Partz instead of GM Genuine Parts), it could be counterfeit. Counterfeiters often use colors, artwork, and fonts on their packaging that are similar to that of the genuine product.
  • COMPARE PRICES. Extremely large differences in price should make you suspicious. Keep in mind that you get what you pay for; materials that lead to long product life may not be included in counterfeit parts (such as no FNC coating on counterfeit GM OE Brake Rotors).
  • INSIST ON GENUINE PARTS. A visual inspection of the product may not be enough to distinguish genuine parts from the fakes. Always insist on GM Genuine Parts or ACDelco parts from GM Dealers or ACDelco Authorized Resellers.

How to Avoid

Always buy products from a GM Dealer or a GM Genuine Parts Authorized Reseller. Look for the distinct mark on your GM Genuine Parts package as an indicator that you made a legitimate purchase from GM Genuine Parts.

What Are Patented Parts?

Certain GM collision parts are protected by United States design patents. This means that unlicensed making, using, and/or selling of a protected part could constitute an infringement of a GM design patent. It’s important to know this because the use of non-OEM parts on newer Chevrolet, Buick, GMC, or Cadillac vehicles could constitute an infringement of a GM design patent. When in doubt, always insist on Genuine GM Parts.
