The customer of this brand new GMC is going to so happy when it takes a month+ to get their new Acadia repaired. ### 1/5 — GM has stopped caring *2018-12-02* This is absolutely awful . Great idea with typical very poor execution.. way to go GM. I am on day three waiting on approval , customer very disappointed. Used 4 times, 4 times failed. Wow ### 1/5 — Terrible Program *2018-11-08* Wait a day to get authorization..... or sit on phone for 2 hours. Way to go GM in making another decision that kills CSI and ESI ### 1/5 — No longer works *2017-12-04* Never worked on my older iPhone. Worked great on iPhone 6 and 6s - at least until the latest batch of iOS updates. Now I just get an error message when trying to log in. “Service workbench is currently inaccessible”. iPhone 6s with iOS 11.1.2 ### 1/5 — Crashes *2017-07-06* After putting in user name and password the app crashes. Happened after iOS 10 ### 1/5 — Help, I Forgot password and user name *2016-07-22* Help I forgot my user name and password and there's no link to change it! **Developer response:** Hello, thank you for reaching out. User names and passwords can be reset in Global Connect. Hope this helps! ## Most critical reviews (10 lowest-rated) ### 1/5 — Not good. *2026-03-03, version 3.14.1* Battery drain Ever since, known well at the dealership, I downloaded the app the iPhone battery as gone down 10% without even using the phone because I am at work. ### 1/5 — Another GM fail *2026-03-02* Not everyone has a brand new phone at work. Why would you make a simple program no longer work with old iOS? Worked just fine before. ### 1/5 — Can’t log in anymore *2025-08-04* Used to be a really good app. Ever since Microsoft entered the app is trash. Can’t get into it. GM is no help ### 1/5 — Why does gm need to collect and sell my data? *2025-04-23* App never sends the email I have to manually do it. Trash app ### 1/5 — Log in *2025-03-07* Used this app all the time with no issues. They update to this new log in and needless to say they broke something that worked fine. Leave Stuff Alone!!!!! ### 1/5 — App is very buggy *2024-06-20* The app is very buggy. There is no notifications when a response is given. When looking through history for an older pra, a pra won’t be there but close the app and reload it will magically appear. The app wont zoom properly to take photos. **Developer response:** Hello. Sorry for the issues you are experiencing on the CSMT app. Please fill out an Escalation Report Form, which can be found under CSMT support. Once the form is submitted, our IT team can begin investigating the issue. Thank you! ### 1/5 — Horrible *2024-05-13* App is junk, can’t submit parts, can’t add photos to fprs that were taken outside of app. Why are you forcing Canada to use this pos. Go back to the old way that worked. ### 1/5 — File upload and feedback *2021-10-08* The app will not allow me too upload pics/vids I took during my repair. It will open the camera too take current pics but won’t let me upload pics I took previously. Also when you attempt to write feedback under the option it does not take you too the next screen too type in your feedback concern ### 1/5 — Worthless *2019-03-20* App will not allow me to send to GM. If GM is going to create an app then it should at least function!!!! I called GM they blamed Apple and gave me a phone number for Apple and they said GM is the problem. Can somebody please fix this issue!!! ### 1/5 — Features removed *2019-01-30* It’s was a decent app until accessing your camera roll was removed for the pictures ## Most praised reviews (6 highest-rated) ### 5/5 — Rpt *2022-11-22* Great tool. Should be able to do more than One part at a time that’s the only down side for now **Developer response:** Thank you for your review. We're always working hard to improve the app and appreciate any feedback for future enhancements that we can incorporate. Please use the "Send Feedback" feature in the CSMT Application to forward your ideas directly to our team. ### 5/5 — Autorisation préalables *2021-08-30* Excellent système efficace et convivial Très utiles pour le département de service Merci Normand Fortier Directeur des opérations ### 5/5 — Internet connection *2021-08-17* I wish the app will let the request to be submitted with the phones internet and not to wait for a WiFi correction **Developer response:** Hello, thank you for reaching out. In order to submit using your devices info, navigate to Settings and turn off "Submit over Wi-Fi Only". This will allow submissions to entered without waiting for a Wi-Fi connection. ### 5/5 — Dealer Review *2016-02-11* We all should be more involved in making products better. This app helps do that and it's easy to use. Goes directly back to GM. I think the video application could be improved. ### 2/5 — Unable To Focus Camera *2023-02-28* Pretty handy on the Samsung I have but when it comes the iPhone 14 Pro I’m unable to use it for scanning the QR code such as for the heated ventilation seat modules. Not a big big deal since I could use the secondary phone. But could be an issue with others. If that could be resolved that would be fantastic **Developer response:** Hello. Sorry about the inconvenience. Please center ONLY the QR/Bar Code portion of the label within the red brackets. In case the issue still persists, kindly send the error details using the "Send Feedback" feature along with the Application Logs so that we investigate the issue. ### 2/5 — Email Submission of RPT *2022-05-19* I just downloaded the app today to submit an RPT for RRAB recall and when submitting the RPT, I got a message that said the app uses the “default Mail app” and that I have to set up an email in the default Mail app to submit. It would be better if I could choose which “Mail app” I want to send the email from (default Mail is my personal email; Per IT, I have to use Outlook for work email), or if the app could submit without using email since we have to sign in with our GM Global Login ID and password. Also I HAVE already set up my “default Mail app” with an email so I don’t understand why I couldn’t submit the RPT. **Developer response:** Hi Alexander, we apologize for the confusion. We are working on an enhancement that will pull up the user's default email application when sending a RPT email. In the meantime, the app currently brings up the Apple email client, which has your icloud account and other emails set up in the Mail Settings. In case the issue still persists, kindly send the error details to csmt@gm.com along with the Application Logs so that we investigate the issue. --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
