OnStar website sign in isn’t working
What is wrong with onstar? I cannot sign in as the page loops back to main page when I try to log in. My car is not connected to My Cadillac app and I can’t use any features.

It’s August 2026. And this seems to be going on for the last year from reading. Clearly server and backend.
I’ve done ALL methods mentioned. Different browsers, devices, App doesn’t work, a new device freshly activated it does it on. This is not a user issue. This is the sites backend. Your IT team needs to get on it. I WAS gunna subscribe so I can use features. But for the past couple months to now of trying to I have no interest in becoming a customer.
then why am I here? I dunno just another voice to add to these people to say. Fix your backend. Fix your domains. It’s your website. Is my word or really anyone’s word gunna reach anyone? Probably not. But I know for a fact. This issue is causing potential new customers from getting your services. Not everyone likes talking on the phone. Or going through live chats.
Like for real. I just wanted to get my 3 months and get connect to use remote features to be able to start my car so it will be cool when I get in during this heat. Which honestly. I don’t get why those features are locked behind a paywall because it’s quite common for it to be free. But hey, what do I know. Anyways. Hope you eventually fix your website. So these kind people can actually access their accounts or become potential customers.

Still happening. I wasn't sure if I could get a trial because I bought my GM car used, and was planning on paying for a month to see if I used it. So far, OnStar has lost at least 1 customer.

this is still happening and I have NEVER been able to login to this account on mobile or desktop. When I try to call it always sounds like the person on the phone is in a wind tunnel and I can't get anything accomplished. CLEARLY this is a website issue that needs to be corrected.

All I want to do is cancel my membership!!!!

You don't need to look further into the issue. It is simply a website flaw that needs fixed. It has been the same for many months.
Still happening in June 2026

This is still happening to me as of June 24th, please fix this. I’ve tried on desktop as well and still did the same thing. Everything else works fine but I can’t purchase any plans since I cannot sign in.

I have tried 4 different browsers and cleared all caches. I cannot login to my account and see any transaction info. The website has been stuck in the same loop for several months. It should have been fixed long ago. I called customer support and told them as well, but still no change.
I am having the same problem. O cant log on and it loops me back to the same page. And I can't access the guardian app even tho I have apparently been paying the service for a while. I have sent 2 help requests in on the app with no response. If it isn't figured out soon I'm canceling my service. This is frustrating.
