1. 5/5Less than 1 star

   I already pay for onstar ... and now apparently to use the MYGMC app I’m supposed to pay again. Other brands do all this for free. No onstar required. But added to all that - the app didn’t work before the update and now won’t even open properly. Other reviewers have experienced the same issue. And no GMC - I’m not doing anything more than report the app here. I’m not wasting any more of my time with instructions to then report issues via email. This is your business and your problem to fix from the app responses and ratings. It’s crippling your branding a little bit more everyday. It’s horrible customer service and will be remembered by many of here when it’s time to buy a new vehicle. I shouldn’t have to pay onstar or you to unlock my vehicle remotely by an app or start my vehicle by the app. It’s horrible service to your customers. Let me add that I pay for premium WiFi and it fails continuously and requires a phone call to have it reset. It’s horrible customer service and these are services that customers need and require in 2024.

2. 2/5Nice Features, but EXPENSIVE Plans

   The app has generally nice features. While we were in the “honeymoon” phase after buying a new vehicle, it was very handy and worked well. However, after the one month trial period, to take advantage of all of the features, you need to purchase an additional plan. As of this writing, the cheapest plan is $15/month. That is in addition to any OnStar plan you are also paying for (again, as of this writing, the least expensive plan is $25/month). You can choose a plan with OnStar and app features, but there is no discount given. Overall, displeased with GM. But as I said, the app works well. Of course, not sure how many times I’ll use it to look at the owner’s manual, which is about all I can do with it now. Unfortunately, it is difficult to divorce the app rating from the “total service” rating, which would include the service plans and pricing. I tried to strike a balance. The app would get 4 stars and the service 0, which to me equals 2 in total. In the end, I cancelled the OnStar plans on my new truck and my wife’s Acadia (which, oddly, still had full app access without having an additional plan... surely an oversight that would have eventually been corrected). I just didn’t see the value. I had always liked the OnStar concept, at a reasonable price. And the app functions were a nice add on to the monthly OnStar service fee. But with the plan pricing now making the unique OnStar service less of a value, GM is indistinguishable from other auto manufactures.

3. 4/5New to GM but loving it

   First off I’ll start by saying this is an awesome app. I love having the ability to check fuel levels, oil life, driving habits, pretty much everything the app contains. The only thing that would make this better in my mind is if there was a 3D virtual image of my truck that I could see, or at least something that resembles it, so I could check if it’s locked, if a door was left ajar, if it’s running, etc. at a glance instead of having to check a log that showed the last time a vehicle function was accessed. That would also give users a chance to swipe between multiple GM vehicles and check their status, or even see them in a garage format. This is just my two cents, and I have no idea how to develop an app or anything like what I described above, so kudos to anyone who can put this into action. Other than that, it’s a great app and definitely very useful. I’m sure once I’ve had my truck for more than 24 hours I will adjust to the app and it’s functionality, and find many more useful features that I haven’t discovered yet. Four stars for now, and I won’t even hesitate to go five stars if this is incorporated into a future update. Great app!

4. 5/5Very handy!!

   • Since my vehicle uses a fob to start, my keys are not usually readily accessible, . . . my phone on the other hand is nearly always quick access! • I love being able to lock/unlock my vehicle from anywhere I have internet service. There have been multiple occasions I’ve left something in my Yukon for someone to pick up or made plans for someone to drop items off without having to be present. • Starting the vehicle on very cold evenings when the convention starts to wind down, the event is almost over, etcetera is fabulous! No need to be within eyesight of the vehicle. (Just don’t leave a key fob in the vehicle, that will deactivate that option.) • Checking the odometer when having a service, peace of mind via locating the vehicle when my spouse can’t be reached by phone, fuel levels, tire pressure - all are fantastic features! ••• Unfortunately, the app no longer works with my or my spouse’s Apple Watch. We have 2 GMCs that we were previously able to control with the watch, but haven’t been able to since early December ‘19. Miss this feature!

5. 1/5App update...now doesn’t work!

   I used to use this app daily as part of my daily routine. Each morning I used the app remote functions to warm up my car as I got ready for work. Since the new update, my remote functions are lost, all my data is gone and it doesn’t recognize I even have a plan with Onstar. I’ve tried several times with customer service to try to get this resolved as it’s been an inconvenience not to be able to use the features the app provides and not to mention still paying for it when it doesn’t work is a little frustrating. The customer reps keep talking me through the same steps...delete app and reinstall, log out and log back in, pull down on the main menu to let it update (doesn’t even give me an option to pull down btw) and been told twice that this issue has been escalated and will receive a call back. First time I received a call back, the lady was short and rude and walked me through the same steps as before and again said it will be escalated and I will receive a callback. It’s been 3 days as of today with no call back and an app that still doesn’t work. Worked fine before the update, now it’s like I’ve been erased off the data base all together. Unhappy Onstar customer and I’ll be canceling my service. Amazing that no one from Onstar or the people that created the My GMC app and responsible for the update that crippled my app can help fix this issue.
