VIU - OnStar System Error code
Thank you for bringing these hardware concerns to our attention. Please know, a red LED light near your OnStar hardware may mean a visit to your dealership is required. If you haven't already, you can push your blue OnStar button to run an On-Demand Vehicle Diagnostic. A live Advisor will be more than happy to assist. If you have any additional questions or concerns after speaking with them, our team here is only an email away at socialmedia@gm.com. Be sure to include ATTN: OnStar Community/SLW in the subject headline.
I just purchased a 2024 Colorado on July 8 2024 and have the exact same problem. At 400 miles a notification saying “service emergency calling” appeared and the ONSTAR button went red. I’ve tried talking to OnStar three times and they insist it’s a check engine light and that I need to call the dealership. I checked with the dealership first before calling ONSTAR and cannot get them to understand that it is NOT the check engine light even though they keep insisting it is. I confirmed its an ONSTAR issue and called OnStar, but after speaking with three different people and sitting on hold for 12 minutes I gave up. Terrible service.
