myGMC Reviews

I used the old app every single day to start my truck from my office. It worked great. With the new app, the connectivity to my truck doesn’t work at all, and the user interface is terrible. Multiple times I’ve tried to start or unlock my truck and myGMC stalls out, doesn’t start or unlock, and doesn’t give me feedback on success or failure. myGMC also forces you to press and hold for commands - this is a stupid user interface decision. It’s a phone - don’t make me press and hold a button, and single press will suffice. The Apple Watch app is broken as well. Even after uninstalling and reinstalling myGMC , my watch still says I’m logged out and need to log in and select a vehicle on my phone. This is extremely frustrating, and dangerous in the event that I want to leave my phone somewhere (like to go on a run) and am depending on my watch only to lock or unlock the vehicle. Please GMC, fix this, it’s the entire reason I pay for a monthly plan.

nothing but issues with myGMC non stop, when i hold the button to start then it says send then does nothing at all or at times when i try to start it and hold start it won’t do anything at all but i can lock or unlock my vehicle which is odd but i don’t know if my truck even starts while im about to leave work until i reach my vehicle , i have to continuously to log out and back in or even delete myGMC to start fresh and that still doesn’t correct the issue, then when i use my face ID it never works half the time i turn on face ID and when i close out myGMC and when i go to use myGMC to log back on it once again ask me if i want to use face ID and sometimes it works without re-saving my settings for it, i have even called on star with the starting issue they open a case up for me with all the troubles i’m having with myGMC, i just want it reliable and working properly as it should be i have a 2022 duramax diesel and i rely on myGMC which i can’t do so please fix it

I purchased my $70,000 truck with all the bells and whistles. One of those “bells and whistles” was the remote-start via the GMC app. Here in Phoenix in the summer this feature is really handy to cool the truck down for awhile before getting in as one can imagine. However, I try starting my truck on one hot day and my app NO LONGER WORKS. I tried resetting my password which their system allows you to get about half-way through the procedure and then the emailed link to me had “too many re-directs” and kicked me off. My next step was to call customer service. After several attempts I was finally able to talk to CS. He told me “Oh, the remote feature was disabled to all who don’t subscribe now to On-Star”. I said “WHAT?? I’ve been using myGMC for about a year and one-half and now you simply turn off the feature without any warning to your customers? That is REALLY CRUMMY customer service. It really is a “bait and switch” scam. I give myGMC one star only now because of really poor CS and Bait and Switch antics on the part of GM.

I used to use myGMC daily as part of my daily routine. Each morning I used myGMC 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 myGMC 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.

myGMC requires us to log in every few hours to daily despite engaging the “remain logged in” button and acknowledging myGMC will remain logged in for up to 365 ? days. Face ID and other security routines also engaged. It’s a real pain to constantly log in and defeats any convenience myGMC , and especially Apple Watch functionality, could offer. If you look back through other June reviews you will see many complaints regarding this issue from many users. It is not a problem with our phones and it would be nice if someone cared enough to address this issue.

UPDATE Sent the above in previous as well as emailed you as requested. Also called on star connection rep and she was unhelpful, only stating myGMC has issues. The problem remains in existence and I’m not sure why someone will not fix it. Look at all the other app reviews commenting on the same issue. myGMC logging out on the phone and especially the Apple Watch is not convenient or acceptable. Calling tomorrow to cancel on star connected services as there is no point paying for myGMC developers unresponsiveness.

When I purchased a 2017 Acadia and a 2018 Cruze it was supposed to come with 5 years of free basic connectivity for Onstar which included the ability to remote start and lock the car from myGMC as well as some diagnostic features. It seems now that maybe none of that is included in that 5 year free basic service anymore after the new update to myGMC . There is no way I’m going to pay 15 dollars a month to be able to start and unlock my card from an app. This seems to be something that should be just a basic free feature in 2021. On top of all that now the only thing I’m getting now is phone calls from dealers telling me to come get my oil changed because they are monitoring my vehicle diagnostics. If they are going to use Onstar to track my vehicle and try to sell me services they could at least continue to provide that basic service. Now all I have is an app that is worthless. I guess if I’m going to get nothing out of it, I’d also like them to quit using Onstar to try to sell me overpriced oil changes and quit calling me.

Used to love myGMC, it worked great to start my car or lock or unlock my doors from my phone or my Apple Watch, which was amazing to me and those around me alike. I enjoyed these features so much that I was willing to pay for it once my free usage went away for my 2015 terrain. Now, however, myGMC won’t even open. That @#*%$ little processing wheel just keeps turning and turning and turning and turning and turning and turning....and turning! Then myGMC never opens. STILL PAYING FOR myGMC . The last time I was able to get it to open it wouldn’t start the car with me standing next to it. I used to be able to start it from Timbuktu with my car safely in the Target parking lot. Wouldn’t lock or unlock the doors either. I used to think myGMC alone was the reason that I would keep buying GMC’s. The convenience was that useful for me. Now I can freely look at other vehicles as I become ready to upgrade without FOMO on the GMC app. Surely whatever sloppy software other brands are throwing out exceeds this nonsense.

1* because of most recent update!!! While I enjoyed using the OnStar app and was subsequently forced to download myGMC, it worked just fine when I originally downloaded it years ago. NOW it’s complete garbage! Can’t access any unlock or lock controls for my truck (2011 Sierra). There’s times I need to know I’ve locked my vehicle but am unable to even get any “buttons” to appear on myGMC Home Screen. Have logged out, logged in, uninstalled and reinstalled all to no avail. The status bar tells me I need to schedule maintenance, I JUST had it done last month. I don’t drive a ton; and use myGMC to check the status of my tires and to unlock and lock my vehicle while I’m at work so as to not have to retrieve my keys from my locker at the other end of my place of work just to run to my truck and get something.
This is unacceptable, and is apparently not a “one off” issue, I just read a review stating almost the exact problem I am having. I really don’t want to have to wait on a customer service all back! FIX myGMC!!!!

Living up north in the winter remote start from myGMC was a selling point for me. I owned a Chevrolet Impala and always used it on those cold winter night here in Wisconsin. I traded it in for a GMC Terrain Diesel with the same app capabilities. I owned it a couple of short months and myGMC no longer works without paying for it. Now winter is upon us and I'll have to pay extra every month if I want this feature. What a disappointment. Working nights on below zero temps and I'll have to wait until I'm in a straight line of sight to start my brand new GM vehicle. Unbelievable ! It must be a cost savings at the expense of there customers. I can't afford anything more. I will be looking into other manufacturers options available. I love my Terrain but absolutely hate myGMC and what GM is doing. This may be my last GM I ever buy. Beware folks! It's sad General Motors seems to be losing focus on its customer services. Cutting corners in all the wrong places. Put it back in order or lose another loyal customer. Help me help you ! Turn this service back on as a benefit of owning a GM Vehicle. P****d off in Wisconsin .....Griddy

I bought my 2020 GMC Sierra and was excited to have the digital access to my vehicle for remote starts, unlock etc. After using myGMC I am really disappointed with the software/security choices. My wife’s Ford Expedition has the ability to schedule starts I.e. Every morning Mon-Thurs at 0700 the car starts and warms up before she has to take the kids to school. I can start the car with either my watch or myGMC . GMC excludes features like this, likely due to restrictions from Onstar. The GMC Apple Watch app is completely useless. If I attempt to start my truck on my watch I have to open up my phone and use faceid to unlock the function within myGMC and then use myGMC on my watch again to actually start the car. The fact that I have to use faceid every time I remote start the truck is also absurd. GMC missed the mark when it comes to convenience technology that actually makes your life more convenient. Drop faceid requirement for remote starts, add the ability to schedule starts, and let me start the vehicle from my Apple Watch without having to open my phone and use faceid.

Oh hey same feedback with the latest update. First of all, AGAIN, I was forced to update my app to unlock my car while I’m standing in the freezing cold.
And all of this still applies:
Just when I thought myGMC couldn’t get any more useless- they surprised me. Literally standing in the rain trying to unlock my car, and a forced update left me stranded. NOTHING is that important in your “update”. Tried to use my watch to unlock- it didn’t work- Says “log in and select a vehicle on your phone” WELL. I am trying to use my watch bc my phone isn’t available- what use is a watch app if it literally never works without your phone? myGMC is a JOKE and I’m not JOKING when I say that I won’t be buying a GMC vehicle in the future if this continues. I’ve updated my watch and phone apps several times. The watch app USED to unlock my car- but now it’s just a party trick I could do if I had my phone next to my watch.

I purchased a new GMC Terrain last week. Previously I owned a Chevrolet Traverse. myGMC is useful and exceedingly better than the myChevy app. However, the Remote Personalization function, quite possibly the most convenient function, has yet to sync with my vehicle. I am able to use every other app function: key fob, vehicle status, vehicle locate, Wi-Fi Hotspot, OnStar account information, and turn-by-turn navigation. I’m signed into the same account in myGMC and the vehicle. If I were not, as I understand it, those other functions wouldn’t work.

Five days ago, I signed out of myGMC and signed out of my account in the vehicle as well. I then signed into both again, waited several hours, went on a drive, and, after 45 minutes of driving, the personalizations I set in the this app app - both in-vehicle apps and favorites - have yet to sync.

I’m able to download apps *in the vehicle* through the 4G LTE connection. I’m also able to *manually* set favorites as well. Since downloading apps and setting favorites work in the vehicle and every other function, except remote personalization, work as expected in myGMC , I have to presume it’s a flaw in the this app app.

If this problem is resolved or if I discover that the error is mine, I’ll rate myGMC five stars. For now, it’ll remain at three.

Since the redesign and update myGMC 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.

I love myGMC. It’s great to be able to start my engine and lock my doors and unlock my doors from my iPhone. However, it needs a little more development to be truly convenient.

To reach its full potential, I need to be able to adjust my heater, defroster and air conditioning to the temperature and fan speed that I want while the vehicle is warming up. When I go home after work, I’m not always thinking about what the weather is going to be like in the morning. When I get to work in the morning, I’m not always thinking about what the weather will be like when I get off of work. I need to be able to change the air conditioning and heating from my phone when I’m warming the vehicle up. Sometimes my windows are iced over a little bit and I want to turn on the defroster at maximum heat with maximum fan speed.

Another thing: I don’t like being limited to having only 10 minutes to run my engine. If I have a situation where I need my engine to run longer, I want to be able to adjust it myself. It looks like some left wingers are running things at the GMC app laboratory. I don’t like being controlled like that. I know what I need more than you do, give me the controls.

I don’t like being limited to two iPhone-initiated engine starts. Again, give me the controls, because I know what I need more than you do. I don’t need some left winger controlling my life and telling me I can only have two engine starts.

Overall it's a solid app. It does the basic stuff well. I primarily use it for remote start which is great since its essentially unlimited range. I've also been able to unlock my wife's truck for her when she accidentally locked her keys in it. It works well the majority of the time, but can sometimes have an issue with a signal getting through if you're in a parking garage - which I assume is a function of the service provider not myGMC itself. Overall its a very convenient tool to have.
One thing to watch for -- if you have two GMC vehicles on myGMC , double check to make sure you have the correct vehicle selected. I have started our other vehicle by mistake when it's sitting in the garage.
To the developer: it would be nice if the banner image reflected the vehicle currently selected, instead of a generic GMC line up. That would provide an easy identifier for those of us with multiple GMC vehicles to quickly confirm which vehicle is selected. Even allowing the user to upload an image would be a useful option.

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 myGMC 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 myGMC 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!

Update** I signed out and signed back in. Everything is working nicely; well done! I’ll leave this here so others can see the easy fix!

Original Post: I like the new look, but the new app lacks functionality. You can’t get vehicle updates like oil life, tire pressure, etc. The page is blank and when I pull down to refresh nothing happens. I’ve lost all my dealer info and no longer see the programs I’m signed up for like OnStar, WiFi, etc. Also I’ve turned on Face ID to log in, but each time it turns that off and a PIN is required to open. Finally, no place to inform anyone of these issue in myGMC , so unfortunately need to share these issues in a review. I hope these bugs get fixed, the dashboard is fresh and looks to be a nice update.

***UPDATED (see my original review below)***
After my original review, several emails, etc., myGMC finally began working correctly. No official determination on the actual problem, but I’m happy that it actually works. It IS a GREAT app and I’m happy to be able to leave a positive review. Both OnStar and GMC are awesome companies that have excellent customer service.
********ORIGINAL REVIEW********
I LOVED myGMC, until it updated and took away all the features I use... Those features may still be there, BUT since myGMC refuses to identify my OnStar account (which I have confirmed is current with OnStar), I can no longer use them. So, I cannot remote lock/unlock or start my car, check diagnostics, send addresses to my navigation, etc. All these functions are the purpose of myGMC for me, personally. I am very disappointed.

myGMC is one of the better mobile apps for in car access. It is fully loaded with variety of useful information and access. I like the remote personalization the best, you can customize the settings in your car from your phone plus there is the ProGrade Trailering, overview of car status on the main page and owner’s manual among many others. There is also the second page that gives a more in-depth info on the status of the car such as fuel level, tire pressure, oil life, diagnostic info etc

My only two issues are there is no way to tell if my car is locked at first glance. Two radio buttons in myGMC show ‘lock’ and ‘unlock’ but no ‘locked’ button. Also, there is no way to set the temperature during the remote start.

myGMC has always worked perfectly until today. I keep getting a message that states that my information is being rerouted by a third party process and myGMC stops processing data. The message tells me to uninstall myGMC and download the latest version from myGMC Store. I have done that several times along with powering my phone off and then back on. Nothing works. What do I do now? Please respond to me. Thank you.

Update:

I did not realize that there was an update to iOS 14, mainly iOS 14.1, when I wrote this review. After installing iOS 14.1, myGMC is working perfectly now. This is a great app as it always starts my car no matter where I am. Sorry for the bad review.

I loved myGMC. It was awesome for navigation and for the key fob option for my truck. I’m not sure whether it was GMC or OnStar that changed this to a paid benefit of myGMC, but I will most definitely be searching for a company in the future that supports its customers appropriately, not nickel and dime them after they already pay a premium for GM’s luxury line of vehicles. I understand that OnStar’s service is a paid subscription, but these two options were included as a freebie for using myGMC.

Typically, companies move forward producing better, more advanced technology. I would not expect to start charging for something that was given to customers for free as far back as 2015.

Now I will have to reflect my rating as such, and ultimately delete myGMC unless something were to change. I would invite others to do the same.

So after two years of having a General Motors vehicle, a GMC Yukon Denali and having basic OnStar which I feel should have basic features I have had my send to navigation option taken away from myGMC after two years with no notice and no consideration for the fact that we own multiple General Motors vehicles.

you took away navigation from the consumer in order to force a sale of higher priced OnStar services which I feel only makes your product now look less desirable and I hope that everyone reading this will consider not purchasing a General Motors vehicle based on the heavy-handed approach that you have taken and taking away the liberties of a simple send to navigation.

I noticed that as developer you were leaving remarks back to bad reviews please don't bother leaving a standard copy and paste remark telling us about how awesome General Motors is when all you do is take away features and force people to pay for things they didn't have to pay for before.

I moved from Jaguar and Land Rover to GMC and Cadillac, I have owned BMW and Mercedes very happily. As quickly as I divorced them I will divorce you General Motors and I will go back to your German adversaries. This is an absolute shame in business ethics that you would resort to nickel and diming a simple navigation feature to try and push your ill prepared and very non-feature-rich OnStar services.

I travel for work and the main reason I purchased this vehicle was to utilize the remote start app. When I land in Chicago and the truck is frozen I want the time I spend getting to my vehicle having it warm up. But if I’m gone longer than 5-7 days it stops connecting. Usually 3-4 days is the max I can leave it and have myGMC still connect. Usually I’m gone for over a week and it never works. I’ve even tried to lock the doors everyday to maintain a connection but that stops too after 5 days or so. When I’ve called numerous times the customer service agent says the same thing...reload myGMC . Doesn’t work. So many times I land and myGMC doesn’t work, so I have to get to my truck and warm it up for 15 min and this many times causes me to now hit rush hour and doubles my drive time to Wisconsin.

Because even though I set it to save the pin for the watch, after some time it seems I must open myGMC on my phone and use it once before it allows me to scream with glee using it on my Apple watch. Then get pouty when it stops knowing that my watch is on my arm and not some strangers. Never an issue on my phone. But an issue with my watch that GMC made me feel Yay! On my watch. If I feel unsafe I can use my watch to toot my horn, crank it, unlock it!! Nope. I be dead right now if I tried that while my phone is buried in my pocketbook. And where is the means to send thoughts to the developer. Being forced to say my thoughts in a review that will be less than 5 stars? I like reaching out privately and giving developers a chance. Please make my watch work great with myGMC . So I can bring up this app on my watch ready to TOOT and UNLOCK when feeling like trouble brewing.

I am out of my 5 year free subscription to the ‘Remote Start’ package on my truck. I reactivated the subscription last night because I figured the watch app would allow me to start the truck from inside my work, since we aren’t allowed to have phones inside due to sensitive information being present. Unfortunately the watch version requires a connection to the phone. I have cellular service on my watch, and I feel the watch version of myGMC should also work through the cellular on the watch if the phone isn’t close enough for a connection. The only downfall. Not going to renew my monthly subscription since I had to use the fob in my pocket anyways, when I got within 150 feet of my truck.

I have been using the My Chevrolet app ever since it came out. It will not stay logged in, says session has timed out and gives a 401_1 error. Once I get logged in myGMC will work for a brief period of time and then logs out of the system

I finally downloaded the My GMC app and it stays logged in. They appear to be the same version except for the logo screen. What gives?

With the My Chevy app I totally removed it from the phone and then reloaded it several times at the direction of an OnStar rep. Rebooted the phone between installs and it still does not work. Have received three calls from OnStar team in Austin and went through the same procedures again several times all to no resolution. Have been told that they would get back to me with a resolution but so far have not received one.

I installed the regular branded OnStar app and it seems to stay logged in but there is no Touch ID function in that app?

Am now still using the My GMC app and it so far has stayed logged in but I see others using myGMC are having the same issues as I was on the Chevy app. Something is wrong with this latest version of all of these apps and needs to be resolved.

When I found out this was a thing for vehicles my first thought was, “for why?” But then after my first trip leaving my truck at the airport not remembering if I had locked up my truck or not, knowing my key’s signal could. It reach I tried out the lock system. myGMC let me know that my truck locked up. The. When I came back from my trip I did not remember where my truck was parked. myGMC let me know where my truck was located. I was even able to honk the horn to find my truck.

In another situation we had our windshield cracked and the repair man needed to take my truck but I was in a meeting at work and couldn’t leave. He texted me that he was at the truck so I simply unlocked the truck and he was able to do the repair and texted me when he was done so I locked it back up.

The starting the truck was a little weird cause my thought was if I am near my truck than, my keys will reach but it does not work when you have to park a block away and your truck in in a parking garage. In the winter months I get my truck all warmed up before I take off now.

The watch app needs some work. Every operation has to be done twice.

I have on star on my Malibu and GMC Acadia there was a large piece of wood in the middle of the road and before I could steer clear it hit both my driver side and driver side passenger tires denting in the rims And ruined both tires on the Malibu Understandably I was freaking out thinking about the super expensive tow bill and having to replace both rims and tires. After calling family and no help there I decided to push that little blue button and they completely saved my day I had no idea free towing came with the package I can full heartedly say I love onstar and they have earned a lifelong customer. If you have a GMC product get on star it’s money well spent!!! P.S my wife loves it to when she gets lost.

There are too many places where you have to use a password or touch ID. You should have to use touch ID to unlock your truck to start your truck but not to lock your truck. You should have to use your password only once, like every other software to enter the program. Once you’re in the program you should be able to do what you want to do without having to use touch ID every time you want to make an action.
Other than my complaint about the use of a password, which is why I gave it four stars instead of five, the program is awesome.

Your app worked well. Who messed it up? My app has been updating for 48 hours. No remote start can be found. I even downloaded the app again. This is a fail! fail! fail!

Hi all, I've been trying to diagnose this issue with GM/OnStar Support for 3 weeks now and have gotten nowhere. I bought a new 2020 GMC, and since the beginning the myGMC app has never worked. I have not been able to send remote commands like door lock, remote start, etc. The key fob works fine it's just the app. I'm paying for the appropriate plan to be able to do these things, but they just don't work and the commands always fail. I've created a few cases with GM/OnStar support to try and resolve but and they have not been able to fix the issue after weeks. it's only been some basic troubleshooting (reinstall the app, resend connection commands, drive the car around the block, etc) I can't even get in touch with anyone past the basic troubleshooting/level 1 type of support. My question, has anyone experienced something similar and how did you resolve it? Is there a way to escalate this further with GM/OnStar Support to get this resolved that you know of? I feel really stuck with a service that that I pay for and need to use. their support team is really letting me down thanks!

I do not have any faulty equipment and the GMC app seems to be working correctly for me I have a complaint this is a complaint a very large complaint!!! The display on my dash and the GMC app does not tell me how many miles I have left on my DEF that is an issue it only has idiot lights not happy about that

I traded my 2017 for a 2021 I was using the gmc app for 4 year no problem then bought the new truck and classic bait and switch After a month the app turns off and says you can’t remote start your truck without a subscription to OnStar what a joke hey $60,000 for a truck in GM won’t even give you the damn app for free

After last update Locate Vehicle no longer shows vehicle direction. Just a single dot as if vehicle is stopped.

Not a fan. The new upgrade is awful. I have to hold my finger on the function (start car, unlock, lock) and it takes so long and often multiple tries for it to even work 50% of the time. I can be standing next to my car completely frustrated just trying to figure out out and nothing happens. Such a waste of money!

The app won’t send turn by turn directions to my on star navigation

App says version no longer supported must be updated. When I try to update it will not update and directs me back to the log on page! Uninstalled and reinstalled same results. Any suggestions?

App says version no longer supported must be updated. When I try to update it will not update and directs me back to the log on page

The iphone app crashes all the time, it is self deleted from my iphone 12 pro max all the time, the app on the apple watch never seems to work , and when it does work it takes forever to complete the task requested. 0 out of five for me
