I used to use this app daily as part of my daily routine. Each morning I used the app remote functions to warm up my car as I got ready for work. Since the new update, my remote functions are lost, all my data is gone and it doesn’t recognize I even have a plan with Onstar. I’ve tried several times with customer service to try to get this resolved as it’s been an inconvenience not to be able to use the features the app provides and not to mention still paying for it when it doesn’t work is a little frustrating. The customer reps keep talking me through the same steps...delete app and reinstall, log out and log back in, pull down on the main menu to let it update (doesn’t even give me an option to pull down btw) and been told twice that this issue has been escalated and will receive a call back. First time I received a call back, the lady was short and rude and walked me through the same steps as before and again said it will be escalated and I will receive a callback. It’s been 3 days as of today with no call back and an app that still doesn’t work. Worked fine before the update, now it’s like I’ve been erased off the data base all together. Unhappy Onstar customer and I’ll be canceling my service. Amazing that no one from Onstar or the people that created the My GMC app and responsible for the update that crippled my app can help fix this issue.

The app requires us to log in every few hours to daily despite engaging the “remain logged in” button and acknowledging the app will remain logged in for up to 365 ? days. Face ID and other security routines also engaged. It’s a real pain to constantly log in and defeats any convenience the app, and especially Apple Watch functionality, could offer. If you look back through other June reviews you will see many complaints regarding this issue from many users. It is not a problem with our phones and it would be nice if someone cared enough to address this issue.

UPDATE Sent the above in previous as well as emailed you as requested. Also called on star connection rep and she was unhelpful, only stating the app has issues. The problem remains in existence and I’m not sure why someone will not fix it. Look at all the other app reviews commenting on the same issue. This app logging out on the phone and especially the Apple Watch is not convenient or acceptable. Calling tomorrow to cancel on star connected services as there is no point paying for the App developers unresponsiveness.

When I purchased a 2017 Acadia and a 2018 Cruze it was supposed to come with 5 years of free basic connectivity for Onstar which included the ability to remote start and lock the car from the App as well as some diagnostic features. It seems now that maybe none of that is included in that 5 year free basic service anymore after the new update to the App. There is no way I’m going to pay 15 dollars a month to be able to start and unlock my card from an app. This seems to be something that should be just a basic free feature in 2021. On top of all that now the only thing I’m getting now is phone calls from dealers telling me to come get my oil changed because they are monitoring my vehicle diagnostics. If they are going to use Onstar to track my vehicle and try to sell me services they could at least continue to provide that basic service. Now all I have is an app that is worthless. I guess if I’m going to get nothing out of it, I’d also like them to quit using Onstar to try to sell me overpriced oil changes and quit calling me.
