No stars unfortunately, as all of the other negative reviews posted the last 2 or 3 years. I have the issues everyone else is having and have had the last 3 months. According to all other posts everything works good for a few months then crashes. Almost seems intentional kinda frustrating when you go through and read all the reviews dating back a couple years. I myself have un-installed and re-installed app multiple times. I am not emailing about it does no good.

I am extraordinarily disappointed with this app. It used to function beautifully. Now, it displays incorrect vehicle status information that is from February. OnStar Tech Support has been of absolutely no help. I followed their initial instructions to the letter with NO result - twice. Uninstalling / reinstalling DOES NOTHING. Nor does clearing Cache OR Memory Data. I was told I would hear from Customer Service in 3 to 5 business days. That was 10 business days ago.

I loved this app the first 4 months of having it. I've now owned my vehicle a year and the app just stopped working. I'm not sure if there was an update or what. When I open the app it will show the control options but the only options available to use are lock and unlock. I live where it's really cold in the winter so being able to start my vehicle wherever I may be without having to be in sight of it is extremely useful. The way the app has been I can't do this.
