Horrible app! Should be free! Can NEVER use it to schedule maintenance. Selected schedule service, type of service, select dealership, advisor, method of service, appointment date & time, (the contact info is already pre-installed) and that's it, you can't hit continue, the button stays a shaded gray, as if more info is needed but their is nothing else on the page required. The app could be helpful on wknds, after-hours, shop busy, closed or when you busy it can be quicker, to do in app.

I do NOT like the recent change that puts the vehicle start on the main screen. It is too simple to bump, and if you exit the app before it starts, you might not realize it is running! PLEASE either add a simple confirmation prompt so accidental starts & unlocks are more difficult, or remove the buttons from the main page. Aside from that, the app works well. I have occasionally wished for more than 10 location notifications because they are shared across all vehicles, not 10/ vehicle.

This app used to be great, but since the update, I can barely use it. While I don't love the change to entering your full password every time you sign in, I can deal. It is the fact that I can no longer start my car with it. Just tells me it fails and then locks me out of my car. The locking mechanism just stops reading for about 3 to 4 hours. Can't even use my door locks, nothing reads. I have to uninstall the app to get in. Paying to not be able to use.

This is certainly not the experience we want you to have with the app. When you can, please send us an email with more details to socialmedia@gm.com and “ATTN: myBuick app/Jessica Studley” in the subject line. We would like to look into things further with you. ~Chris
