Congratulations on your new Yukon! We're sorry to hear you're having trouble getting your OnStar services set up. To clarify, are you unable to connect with our live OnStar Advisors when pushing the blue button on your review mirror? If the LED light located next to your blue OnStar button is red or off (normally green or flashing green), that indicates a potential concern with your OnStar module or hardware. It's recommended that you bring this to the attention of your dealership for further assistance. If you have any questions or would like further assistance, please feel free to email us these details at socialmedia@gm.com with "ATTN: OnStar Community/Kcpalmer522192" in the subject line. Our team is happy to help.
