Take it back to the place where you purchased it. Most legitimate dealers/retailers consider their customer service and reputation to be the most important parts of their businesses. And most will do whatever is necessary to make good on the purchase.

If you suspect a part you purchased is fake, or if you know anything that could lead to the conviction of counterfeiters, please contact the GM Global Brand Protection Team and report your suspicions.
