Updating my rating because this app is becoming more & more unreliable! I shouldn't have to keep uninstalling & reinstalling the app for it to work. The issue is with the remote start option in the app. When using it lately it won't start my vehicle and I get the following message: Unable to reach Terrain. Use key to start manually and restore connection. This is a first & there's no rhyme or reason. I pay extra for the app but may as well cancel my subscription due to unreliability!

We realize how important it is that the Remote Start feature functions properly, and this isn't the experience we want for our members. Please send an email to us at socialmedia@gm.com with the subject line "ATTN: myGMC app/MsChelle7" so we can further help. ~Sara

Buyer beware. When you first buy your vehicle the app is easily available. You give GM permission to do all sorts of things, and when your vehicle hits a certain mileage they start charging you. The permission you gave them is still there but they are not providing you any service. They can track your oil change intervals, speed, etc... not for you, but to deny warranty.

We appreciate you taking time to leave a review. We take your privacy very seriously. All OnStar services are opt-in. Members decide whether a connection to their vehicle is activated or not, and you can deactivate at any time. Email socialmedia@gm.com with "ATTN: myGMC App/Richard O'Hara" in the subject line if you need help with this. ~Kyja

No climate control with the recent update. I had the feature when I first purchased the vehicle, then with the update they took it away. Ridiculous for an app that you essentially have to pay for since it requires OnStar to connect. Other, much cheaper vehicles, offer free apps with all the bells and whistles. Support was nice, but essentially useless. Kept having me clear cache, history, uninstall, and reinstall. Never worked, but each rep had me do the same to no avail. Other features work.
