myCadillac App Reviews

Why won't they fix this app? White screen of death- literally nothing works but the logo

Love driving my lyric. The hidden garage door opener, not so much. The sea controls on the door no. But the one pedal driving, superb and having a full charge every morning terrific.

Used to be able to be used on the Apple Watch, not any more and they still haven’t fixed it with this patch. Won’t be buying another car from this company if they can’t keep support on devices, for a vehicle that costs over a $100k you would figure it would be enough to keep Apple Watch support but I guess not

This app is terrible. The miles on my car does not match the miles on the app, I have called on star twice and they have yet to correct it. I am about to cancel the subscription because I am wasting money on something that does not work. As of now it’s a waste.

99% of the time it doesn’t work, features that I was looking forward to like climate control & locking utilizing are basically useless. App lags as well and basically guaranteed to get FAILED attempt every time. It’s 2025 and it’s crazy to think these issues are not resolved already. Embarrassing to speak to other EV owners that have way more reliability from their Apps vs this one. Biggest downfall on Cadillac EV reputation.

Very unreliable. You never know whether or not it will work.

Love it

Features in this app is lacking compared to Tesla. Remote start, auto climate control, and the app is glitchy. Even the Cadillac service representative was having issues when trying to place an order for a part. The idea is great but it’s NOT comparable to Tesla App! It should be better as this is a Cadillac!

The app is ok. It starts, lock/unlock as intended but my issue is with the fuel range/percentage. It is always off by a lot. Even upgrading my software and the app itself. I’m on a iPhone 14 and 16, both pro max.

The app is great for the basics. I feel like the app needs more - more GPS options & functions. The ability to control the AC and heated seats from the AP would be nice.

It takes a lot of time to lock or unlock or even see the change (when it works). And they want to pay for it. In Tesla app it’s updated immediately. Very disappointing

What happened to the tire pressure monitor and status?

All of the GM apps have been terrible. I had a 2020 Bolt and the app was mostly useless. Fast forward to 2023 and the same app with a different color was the Cadillac app. It was still terrible. They have made many revisions in the last 2 years. They took away the Apple Watch companion, which is a major loss. They took away the Updates History. The app has finally begun to work a bit better as of March 2025. I would never pay to use it, as it really isn’t that reliable to warrant a fee. Maybe they can hire on some Tesla engineers to make it more useful and functional.

I just wish it could notify me if somebody was working in my car

I love this app! Only thing that would make it better is to be able to set a timer for the vehicle to automatically start!

4/4/2025 (2-star review, ‘GM Giveth, and GM Taketh Away’) - Terrible job GM with your latest update on version 7.6.0. As you may read in my prior review posted a few days ago regarding version 7.5.0, I had lauded GM (5-stars) on their redesign and fix of all app functions and interface. However, this latest iteration has promptly removed my ability to read the electric charge portion of my vehicle. This review is a 2- star. The electric range API and widget has been removed from my app, and now only displays gas capacity and estimated range. I own the rare 2017 CT6 PHEV. What happened GM, that you cannot test before release? In the IT industry this is called “regression testing”, and it’s meant to ensure that you don’t break something that’s not previously broken. The engineers at GM should be embarrassed. _______________ 3/31/2025 (5-star review, ‘Version 7.5.0 Great’) - Good job GM redesigning and fixing all location and charge status APIs. I own the rare Cadillac CT6 PHEV that contained an interface specific to PHEVs, which GM no longer produces but promises to return in 2027. Version 7.5.0 was redesigned to separate out the gas versus the electric charge APIs and widget interfaces to support ICE, EV and PHEV vehicles. The location Map location services was also fixed. One example of its redesign sophistication is the fact that for my Cadillac PHEV, the “Start” remote control button was replaced with a “Climate” button. It took a minute to realize that this was what was really needed in a PHEV - to warm (or cool) the interior of the car via battery, and that the ICE wouldn’t need to “start”. GM engineering can and does innovate.

I really like how I can look at my car on my phone and see the status of all the functions of the car. It gives you the tire pressure, how much time left on your oil change and many more cool information.

This app never NEVER works how it should or really at all. For such a prestigious brand the tech is garbage.

Have tried over and over and can’t get my app to work. Waste of app space.

Update 4/2/25: Just installed new 7.6.0 update and it connected immediately! Vast improvement. Update 3/26/25: the updated app works perfectly after uninstalling/reinstalling it, as advised by developers. Thanks for your help and for providing us with an excellent, functional app!!! Original: App and web site are useless since 3/16/2025 update. Can no longer log in to the account I have had for years! Verification codes appear to be accepted, but app loops back again asking me to log in. Such a shame this formerly useful app is broken now.

The app data and remote start are sporadic at best. At worst they just don’t work for days.

The concept is great but the information is not always accurate as far as my mileage. And at least once a week I either can’t even get into the app or my car to start even when signals should otherwise be clear. If I wasn’t paying almost 30$ a month these two things wouldn’t matter to me but since I do pay I have expectations of stellar performance.

Endless submission of the same information, with no conclusion.

Love the app everything is great it let me know personally what’s going on with my truck and I can easily schedule maintenance and it keeps me informed on when maintenance is due love it

The app works for a day, but it hasn't worked after that single day. The on-star customer service is terrible, and the troubleshooting to fix the issues is just repeated with each advisor so now I call once a month to get an email about my vehicle diagnostic

Delay on lock and climate

App is horrible and fails to communicate most of the time, wont provide instant information about charge level or able to take any actions for days

After using multiple other car apps I find Cadillacs to be the Best in Class. Easy to use, get points, schedule service, connect with Onstar, vehicle checkup and so much more.

This app needs A lot of work. Lag times are real, and I recently got an EV, searching for public charging stations is whack

I really liked the availability to start our car from my watch. Much faster and less conspicuous. It has disappeared and Cadillac doesn’t have a good answer as why

The app works but not well. Every time I try to send a command I must resend it multiple times for it to work. The commands are often (2/3 attempts on avg) ineffective.

Rides like you’re on a cloud has get up and go that you wouldn’t believe. Very, very nice car. There are only a couple of bugs I would like to see worked out and a couple of changes I’d like to see made but for the most part well worth the money just a great vehicle.

App does everything I need it to do. Would be cool if you could see your current odometer. Can’t wait to get an update to where I can see the cameras on the car when it’s parked. 2024 Cadillac Lyriq Sport 2.

Super laggy and majority of the time the app doesn’t load or controls don’t send to vehicle. Previous Tesla owner and GM has lots of work to get the app up to par

Used to be able to set parental alerts, no longer can

Should be faster but still good app

The app on the Apple Watch is gone

The app does not work well at all. Entirely too laggy. And should give current locked/unlocked status as status of vehicle. And terrible trying to set up charging through the app.

Sadly discovered they removed the Apple Watch functionality of the app, which I had found quite useful, albeit not the most reliable.

Expensive and they don’t help.

Good App with amazing features and controls love it!✨

The app is not always reliable. Multiple attempts requires at times when using the Start function Charge amount not always accurate when charging car

Tire pressure view is larger and cleaner. Unlock shows sent and unlocked statuses while working. And great service from developer to a questoon that completely resolved my question.

Since updating app the connectivity issue is worse prior to updating. It doesn’t recognize vehicle. I have to hold the start button twice as long and after holding it, it still doesn’t start. App is always failing or unresponsive.

Remote start works maybe 50% of the time. My favorite part is when I remote start and the keys are in it and locks the keys in the car and then claims it can’t connect when I go to unlock the car from the app! So I’m standing next to a running car that I can’t get into. Since the update last week, it no longer automatically unlocks the screen in my Escalade anymore so I have to enter the pin every time. Not very helpful.

You pay for this app but it does not tell you or show that your car is locked. My Hyundai app showed everything. This is junk

Finding things in the app couldn’t be tedious. The app should make my experience better, not worse. Setting up, trusted devices and family sharing literally took me hours and finally I had to call And we still didn’t get it set up correctly. I tried to do undo everything, but that didn’t work either.

The updates are great. Easier to use the navigation feature.

Nice convenience

I am really enjoying the features of the app. So glad I purchased this vehicle!!
