I am unable to link my OnStar account to MyChevy account.
We got a 26 Trailblazer yesterday and activated our OnStar account. We have 8 years free of the MyChevy app features (remote start, location, mileage, etc) and a 2 month trial of OnStar.
When I open MyChevy app, it is still prompting me to push the OnStar button to activate. It shows in the vehicle status that there is no OnStar account linked. When I go to link my existing account to MyChevy, the page is blank. I've tried through the app, mobile browser, and home computer and have the same issue.
I called OnStar and they couldn't help. She said she escalated it, but provided no time frame on when I'd hear back. Despite all this the wifi works, but we have no access to the features of the MyChevy app. Hoping for some guidance since phone representatives have not provided any resolution.

I've had the same problems. I called them an still haven't gotten it resolved. I followed all the steps even deleting and redownloading the app. I have the features in the car but can't use the app, which was the biggest reason for signing up for onstar

I have been going back and forth with this problem with OnStar for almost 3 months. Pay for a service and not able to use it for what I really want it for. I am frustrated and getting ready to cancel. They call me back every 3 weeks or so and we talk for a few minutes, rach another road block and they they say they need to call me back again and we are back to square one. I just don't understand how this isnt figured out by now.
I have the same problem. They had no trouble accepting my credit card data! You would think a company like GM would have software that works!

Basically same issue, only now I have two vehicles that I can’t use the app on. Ugg! I have spent hours on chat, on the phone and in my car with Onstar and they cant figure it out.

Same.
I have been using the MyCadillac app since I bought my Optiq in March. Today I went to remote start and the screen with the climate options would not come up. It says the app is not connected to the car and there is no OnStar account connected. (My GM Rewards also appears to be disconnected.)
Called OnStar and they said my account shows as fully active, so they sent me to tech support. Tech support said there was an outage that they hoped to resolve in 2 hours. That was 8 hours ago and I still can't get anything to work. I cannot even log in to OnStar online; clicking "sign in" just refreshes the page without opening the log in fields.
I can find no mention of this outage online, and when I posted to Reddit, other users said they were not having a problem.I am having this same exact issue, just registered and cannot link my account. The page is blank.

Thanks

I have been dealing with it for almost 3 months, it is very frustrating.
We never intend to cause frustration and understand that the duration of addressing this concern with your OnStar Account has been extensive. Please send us a private message to OnStar_Support so we can look into this further. Just select the envelope icon at the top right of your screen to get started.
I did get this resolved and it was a tech issue with profiles not updating. To fix ask the on star team that your account needs a profile update form submitted. It may take some time but it did resolve my issue.
I am having the same issue with my GMC app. I can’t link my Onstar account. When I try to add my vehicle using my Onstar account number, the website says “unable to search, try again later”. I have opened up multiple “cases” with Onstar and they “escalate” all of them but there is never any resolution. I just want to be able to remote start my new Sierra using the app. Reading through these threads, it’s clear that GM/ONstar have an ongoing issue that they are failing to address.
We do understand how upsetting persistent concerns can be. For the best assistance, we do recommend continuing to work with your case advisor. If you had any questions or had any trouble connecting with them, please feel free to send us a private message to OnStar_Support by selecting the envelope at the top right of the page.
