Costco Offering Rebates On GMC EVs In June And July 2025

Between now and July 31st, 2025, Costco members can get up to $1,250 off the purchase or lease of two GMC models, three if you count the Hummer EV Pickup and Hummer EV SUV as their own distinct models. The new GMC Limited-Time Special kicked off on June 3rd and is only available to eligible Costco members. The incentive is also available in combination with available manufacturer incentives.

The discount amount varies by membership tier. Gold Star and Business Members receive $1,000 off of the eligible GMC models, while Executive Members get a higher incentive of $1,250 off the purchase of eligible models. The incentives are the same for every eligible GMC model. This deal only applies to the Professional Grade brand’s electric vehicles, which tend to be a little pricey, so this incentive program can help ease the pain on your wallet when getting your next EV.

To redeem the discount, Costco members must first visit CostcoAuto.com and register for the promotion. Members will then receive a certificate and promo code, which can be presented at a participating GMC dealership when purchasing a new model.

Eligible vehicles include the following:

Costco is also running incentive programs for Chevy and Cadillac models. For Chevy, every EV in the brand’s lineup, including the BrightDrop vans, is included in the program. Notably, the Chevy Colorado midsize pickup is the only ICE-powered GM model currently eligible for an incentive through Costco. For Cadillac, all of the luxury brand’s EVs except the Lyriq are included in the incentive program.

If you’re both a Costco member and a GM Rewards member, you can receive between 10,000-12,000 GM Rewards bonus points when you take advantage of this Costco incentive.

Costco notes that it does not sell automobiles or negotiate individual transactions. All vehicle sales are subject to availability and pricing prearranged with the participating franchised dealer, and certain vehicles may be excluded from the program.
