Used to be able to go into the app insert an address and send to car to help my mom get turn by turn directions. No longer gives you that option and no longer gives you any information about the car except to unlock, lock, flash the lights beep the horn. All other features have disappeared. No longer can locate the car either.

This certainly isn't the experience we like to hear about, Nan. Please uninstall and reinstall the app to ensure you have the latest version. If that doesn't work, send an email to socialmedia@gm.com with "ATTN: myBuick/Nan Trout" in the subject line so we can assist. ~Austin

The app updated now I have to call onstar to get it activated. Why should I have to call and activate when i have been receiving service and paying monthly. I have a monthly subscription. The new app experience is awful. Can't remote start or see any diagnostics. What happened? It says I have to push the onstar button. I'm not in my car. So annoying!!

Doesn't work anymore. Used to work fine but now the app has difficulty logging in finding the car on a map, etc. Not sure what happened but the developers need to fix this. The only way to log in is to use either biometrics or password, but then the app just freezes until it is force closed and reopened. Then, some of the functions just don't work at all (like find my car). When the button is pressed nothing happens. Terrible experience all around.
