Ratings and reviews

Terrible app, keeps making me log in, keeps asking for email AND text MFA and I have it set to off. Slow to refresh...can't connect to certain charging stations only have the option to pick USA or Mexico but I'm in Canada? Couldn't add a card to my account with contacting customer service. They say its weird that my account shows not synced but they don't see anything wrong.

Update June 2026: GM just made it worse. 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.

UPDATE: I've sent the list of issues along with screen recordings. I will keep other users posted on the response. App is incredibly slow to update, sometimes taking minutes to update, especially when it comes to loading charging status. It's a struggle to link public charging accounts to the myCadillac app. I still cannot get my ChargePoint account to link. it refuses to login and I also confirmed it with my wife's phone. I had the MyGMC app previously for my Yukon and it was fast and flawless.
