Real piece of mind

Great app that really does give you a piece of mind on the road. I’m a new driver and don’t feel very confident that I can deal with an emergency situation where my car won’t start or I'd get a flat tire, etc.
And of course, funnily enough, I was recently driving home from university and got flat mid-way through my trip. My dad’s got a GM sub and all the family members are included in the family plan. And thank god, haha! I was able to request assistance in a few minutes and it wasn’t long before help actually arrived, had to wait about an hour or so. The assistant I spoke on the phone with was very nice as well! He really made me feel safe while I was stranded in the middle of nowhere. Anyway, the team arrived, fixed my tire and got me back on the road as quickly as possible! I’m really glad I had OnStar to resolve this for me as I wouldn’t have known what to do otherwise. I would probably panic and start franticly searching for roadside assistance numbers, and then end up just calling my dad.
Having access to the OnStar Guardian app gives me the comfort that, if I ever find myself on the side of the road again, I will be alright!
I would definitely recommend it to any new drivers out there that feel like they wouldn’t know what to do if they suddenly ran into car trouble on the road. And the app is now open to non-GM users, which I think is pretty awesome as more people will be able to use the service.

Great relief

I have only had this app a short amount of time but it has done wonders. I recently added my elderly mother to my family plan, as she has been known to get in accidents when driving. So far it has been tremendous and has helped with my peace of my mind when my mum goes out on drives as she will be able to contact the appropriate services quickly if an accident happens. For the price of $15 a month it is definitely worth it knowing that all of my loved ones are safe and that they have quick access to emergency services. I can understand how some people may be hesitant of purchasing this due to the price but I would 100% recommend this app to anyone the price is worth it! I have added my husband and children in my OnStar Guardian family plan too.

Beware! Major Privacy issues!

I received the email from OnStar my service package would this new Guardian app where I can add my family, share locations with them and be protected in case of an emergency. Sounds great, right? After I downloaded and setup our family of four I started getting notifications for someone named ‘rielly’. No one in my family of 4 is named rielly, and I can see them all listed in the app. No extra people. Yet when Reilly’s battery gets low or the turn on and off permissions I kept getting a notification. So I called OnStar. They said they opened a ticket but there was absolutely no way whoever this Reilly person is could see my, or my family’s location. Fast forward a little over a week to today.. guardian app notification on my Lock Screen that Reilly has viewed my location! So now whoever this person is now knows WHERE I LIVE!!! Spent another hour on the phone with OnStar to get my account on the guardian app disabled completely and they still have no idea who this person is. Deleted all my family members and removed all location/microphone/tracking permissions. Made everyone else delete the app. Now at 1am, I get more notifications that Reilly’s phone is 7% and that “a family member has asked to view my location “. Yet everyone else in my house has completely deleted the app and I have turned off all permissions. This is awful - now I have to worry about someone stalking us. DON’T USE THIS APP!!!!
