Use with a little common sense

Don’t believe everything this app tells you. I set everything up as required paid the extortionate subscription fees ( only for a short while before the messed them up ) and was disconnected mid drive in the middle of a city I new nothing about. To top it off the “find my car” would not and it kept saying my car was being broken into when in reality the in car camera had fallen down . In correct readings, list car high subscription fees not what I would call a good app and to top it off the WiFi Services are being removed with no further information when they will be returned, not what I bought , THANK YOU VAXHAULL FOR wasting £18,000 of my money.

Reading a lot of bad reviews about this app and service but for me it has been the complete opposite. My car was stolen from outside my house the night and when I had noticed the car was gone I phone the police and onstar. Onstar managed to track my vehicles location, Disable the engine and they then informed the police were the car was. I got the car back the next day. Onstar basically done the polices job for them. Cracking service 👍

What an earth has happened!
I’ve lost all the info on my vehicle, all the information is completely missing, and if I locate my vehicle it’s telling me it’s in the wrong place.
Please fix as soon as possible!
App is now working fine, I suggest anyone having this problem is to delete the app, reinstall it and log back in, and everything should be ok!
