Ratings and reviews

The app just text at 5am to say I literally had 0% oil and 0 psi tire pressure, when I had 65% oil and 42 psi when I went to bed. After getting out of bed to check what the problem was, while running the vehicle and sitting in their for a moment the error finally corrected itself. And all the number went back normal. Please fix the bug in the app!! Update: It happened again, I'll be in contact. Thank you, Kayla.

How embarrassing to have an app that you need to be able to rely on especially for charging and it works 0% of the time and it has occasionally worked for my husband. The charging is never aligned, can never change the % to charge to. The amount of miles left is never in sync. And I can never see what my charge is at while its charging. Totally pointless Cadillac should be ashamed to have an app this bad especially when its a much needed app to rely on.

It's extremely slow to communicate with my Lyriq, like unbearably slow. I really wish I had a third party option, because I'd ditch this POS in a heartbeat. It's so bad that's it's not even just an annoyance, it's actually painful to use. I hate it. I hate that I can't just easily change my target charge cap without wondering if the update actually went through or without having to restart my phone because it's quit responding. I have a Galaxy S25 Ultra and always great connection.
