### 1/5 — Pathetic app response

*2026-08-22, version 8.15.0*

App is stone aged. It takes mintues to get updated info… try to make it faster

### 3/5 — Works with bugs

*2026-08-19, version 8.15.0*

The app works and I can see data related to my car. GM had introduced new functionality and reorganize the UX so it’s easier to navigate. My issue that removed 2 stars continues to be with scheduling service. After filling out all my information and submitting, I constant get a “something went wrong” issue. I hope every  time that the app will let me schedule the appointment and it always fails. It didn’t used to fail. It didn’t fail in the prior version before the redesign. GM needs to do UAT to test each and every available selection and submit to see if it works and find the root cause when it fails.

I’m trying to schedule an oil change. So basic and it fails.

### 2/5 — Not the quality I expect from Cadillac

*2026-08-19, version 8.15.0*

The app consistently falls short of what the Cadillac name should stand for. Charge management doesn’t update in real time, I have to close the app, reopen it, refresh, and wait, just to see the current state of my vehicle. Remote start is just as unreliable: it lags, hangs partway through, and often fails to confirm whether the car actually started.

For a premium brand, this is a basic expectation, not a luxury feature. The vehicle itself is excellent. The app is the weak link, and it undercuts the whole ownership experience. Please invest in live data updates and a faster, more reliable connection to the vehicle.

### 1/5 — Sucks

*2026-08-18, version 8.15.0*

You keep changing it

### 1/5 — App doesn’t work

*2026-08-17, version 8.15.0*

The app to vehicle connection is very slow. Remote commands take several minute to respond.  They did recently put out an update and now the command will actually work.  Before the update they didn’t even work.  Feature that are displayed in the owners manual that the car has like”phone key” aren’t activated in the car.  They advertise features they won’t release.

### 5/5 — Love this app

*2026-08-16, version 8.15.0*

Excellent

### 5/5 — Great Application

*2026-08-16, version 8.15.0*

This app is great, very reliable and easy to use.

### 5/5 — Did I forget to lock my car?

*2026-08-15, version 8.15.0*

I love the Cadillac app! Being able to lock your car from bed is awesome! I enjoy being able to order products from the app and see what maintenance is coming up.

### 2/5 — Not as useful as it used to be

*2026-08-14, version 8.15.0*

I used to be able to unlock my vehicle, remote start it etc from the phone app but this option is no longer in my app even though it is still listed in the app description. It was a really useful feature but now the app is pretty useless for me.

### 4/5 — More Feature

*2026-08-13, version 8.15.0*

More can be done and is expected from the MyCadillac app. Keyless driving (by phone) should be a feature. Start Charging (not just stop charging), Car Play should be an option, Google map dark display should be an option, and a vehicle display to change exterior colors.

Just repeating what I said earlier. More can/should be done from the app.
