GM Card Login, Payment, Customer Service
Updated December 6, 2018 – Below you will find the key information you need as a GM Card holder (issued by Capital One) to access your account online, make payments, and reach customer service for further assistance. Note that because GM credit cards (including BuyPower and Extended Family cards) are issued by Capital One, you will interact with Capital One for your GM Card, just as if it was any other Capital One credit card.
