Actually, the app works quite well and has significantly improved in the few months I've owned the car. But I'm giving it a low rating because it's pushing advertisements / special offer notifications at me which I can't disable without also disabling important charging-related notifications. Stop pinging me with special offers and I'll consider a better rating. UPDATE: increased rating since it hasn't pushed any special offer notifications in several months.

This app is slow. Can't rely on it for anything. When you command something it takes forever or it fails. It's not winter yet I think I'm gonna have a hard time to heat up my car at a distance because nothing remote function well. I've had a tesla before, their app works pretty well, you can do everything remotely very fast even access to the cameras. This app is only for reading😁 Even when you are close to the car, the car is not receiving signals, it always fail. app is up to date

I don't like to rate anything bad. App is really disappointing. The tire pressure, fuel level, mileage everything it's different from what it shows in my car. With the app I can start the car. I can also open the tailgate. That's it. Who wants to open the tailgate far away from the car? I can't set, from the app, the temperature inside. GM, please look all complains about it. Groups/FB/forums. Everybody is disappointed with the app. I love my Cadillac but the app is definitely bad.
