App saying unable to reach vehicle
I have owned vehicles with the OnStar app for many years. Ever since purchasing my new Equinox, I have hardly been able to use the app. Most of the time, when I attempt to use any of the functions in the app to control the vehicle, it takes forever to load and then tells me it is unable to reach the Equinox. I’ve called OnStar multiple times. They have advised me to log out of the app. Deleting the app and re-logging in will be a short-term, temporary fix for maybe one use, and then it will go back to saying that it is unable to reach the Equinox again. After multiple calls and them having me test the OnStar button in my car, there have still been issues with the app's function. Fortunately, I am still in the phase where I am getting a free trial from purchasing my new vehicle, but it does not look like I will renew after this if the app still continues to show persistent failures. I really enjoy being able to have this app and do not mind paying for it, but if it is not going to work, I do not see any benefit in paying to have it after the trial ends.WiFi not working - says vehicle is registered in Canada
Bought the vehicle used in the United States from a local dealer in May 2026. Have talked to a OnStar representative every 5 days and they continue to tell us they are working on solving the issue. The reason we have been told that the WiFi does not work is because it shows the vehicle being registered in Canada with OnStar. Has anyone else ever had this issue and has it ever resolved? vehicle is in tier 3 country deadlock.Onstar module
On star module went out. 22000 miles. Dealer said 4 weeks due to back ordered part. Really? Can’t use my truck for 4 weeks? Do you have the link for the class action lawsuit? My limited research found this to be a huge problem. How am I going to get to work? What can Onstar do to make this right?Telematic failure Cadillac Lyric 2026
I purchased my lyric less than a month ago and we just started our very 1 st road trip from Texas to Colorado. Middle of drive, our maps stopped working, the wifi stopped working, supercruise was not available, the in car onstar button would not connect the call. Our cadillac app did not sync to the charging amount of the car when we plugged it in. Please help ASAP2024 GMC Acadia Denali - no data
We have a 2024 Acadia Denali with subscription we bought new. Have full LTE Signal and no data for google maps, account logins etc works. If I hotspot the car to my phone the maps will then load. Its like the sim needs refreshed or reprovisioned. Everything works if we join our wifi to the car also. Its definitely a cellular data issue. I have done all the radio restarts, reboots, cache clearing, etc. How do we get he cellular signal refreshed? We are on a road trip and not near home base. We were trying to rely on the factory google navigation to take us around the area.
