Customer Reviews


I can see where this app is headed, and it still needs some work to get there. I have two recurring issues with the app. 1) I have multiple vehicles, and the app will randomly switch back to the first one in the list when issuing a remote command. I really don't like having the wrong car started and therefore the 1 star. 2) The app will frequently get out of sequence somehow and not be able to issue commands without restarting the phone. For instance, trying to issue the unlock command. The vehicle never unlocks and the app stays in a state of unlocking (green twirling icon). Restarting just the app does not help and requires restarting the phone or reinstalling. Thank goodness I kept the OnStar app so I have something that works. The last issue I have seems to be hardware. My 2012 Escalade and "early" 2015 Denali both take painfully long to receive and execute a remote command. My "late" 2015 and 2016 Denali's both perform adequate. Keep improving the app. I'm looking forward to a stable version.

Two Months and still can't use all of App

This app was not fully functioning before they rolled it out.

I have been trying for two months to use all aspects of the app I was told I had to switch to and I still can't use the Navigation or the Vehicle Status.

I have called four times and spoken to four different people that assure me they can help but no one has fixed the errors I keep getting.

I was in hold twice for 45 minutes (was told it'd be 5-10 minutes) as they updated but nope that didn't work.

I was told I had to delete the app and download the newly updated app supposedly different from the app I was deleting. I told the guy it would show me the one from the cloud but nooo he said it would be a totally different app. The guy obviously doesn't know squat about apps.

I am as frustrated as I could be. I've been told twice now that they are elevating my case to the online specialists.

Don't fall for it. Their tech support is HORRIBLE.

Much better

Much better than the onstar app. The onstar app would tell me my password was wrong at least once a month even though I open the app multiple times a week. Restting the password was a pain if I wasn't at home and if I happened to trust the app I'd be locked out of my vehicle. The new myGMC is fast, hasn't locked me out, and the UI looks great. No complaints so far.
