Very 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!

Functionality is less convenient for the customer

Since the redesign and update the app requires holding your finger on a button to activate the feature. Such as unlocking or locking the vehicle you must hold your finger or thumb on the button for a period of time while short but still hold it until it activates. What I, and most likely other customers, enjoyed more was being able to tap the button and go about your business. The purpose of the feature is convenience so requiring me to hold my phone and watch the screen until I see that it actually activates my request is useless.

Same for starting vehicle… the quick ‘acceptance’ of Touch or Face ID, made this very convenient. Additionally, when opening my app, it prompted a notification that my vehicle had started…. I wasn’t home and my vehicle was in the garage with my 2 dogs. I DIDN’T start my vehicle so I was concern until I arrive home and verify that my vehicle had not started and was not suffocating my animals. Luckily I was five minutes on my way to my house. What if I were two hours away what would I do? You need to add an option to turn off the vehicle and as well a status option telling the user windows being up down partially up or partially down which window what doors are locked or unlocked all of this should be a part of your vehicle status and then as well again allowed to use it to turn off the vehicle if it’s been started remotely or where the key let them turn it off with your phone.

App 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.
