Built in GPS, cellular, and Onstar not working

[blingen1]

2025 LT. Started having issues where the google maps would randomly show car location blocks or miles away from where i was. Tried using onstar button to see if they could check what they show. Onstar button did nothing. Then the built in cellular signal indicator disappeared. Turns out telepathic module bad. Dropped off car for a week for them to repair. Got call it was fixed and working. Picked up the car, drove 2 miles and had same issues. Took car back and 3 days later was told the new telematics module is also bad. The part is now listed as backordered nationwide with no ETA. Oh and had a 2025 equinox for a loaner. The backup camera and backup sensors stopped working on day 2 showing a warning message on screen when in reverse. It also has the ANC issue with feedback sound coming from speakers at 1800 to 2100 RPM--saw there is a fix for that. And when starting the car the android auto volume defaults to max when you first use it--there is another software fix for that also. When I went back and tried to describe the ANC issue, a tech behind the counter immediately said yep sounds like a jet engine hum--pretty bad when a random tech immediately knows the problem on a 2025 model.

I have often said if one Chevy does it, they will all do it. Consistent, in a bad way. Sorry to hear pf all the troubles.

Exactly. My noise sounded like I was between two big rigs but I told them that when I had the CC on at 61 MPH it sounded like a F16 was in the next lane but this was no hum, I described it as more of a roar.

Exact same problem. Just got a call from OnStar telling me that they reset the module trying to help me but the module is probably bad. At one point it had my location 3000 miles away in California. It started with losing Google and then losing OnStar but it was intermittent but now it hasn't worked for a few days. Also had the jet engine in the back seat but a computer update took care of that. Onstar tech assistant said it's probably the Communication Module.

No maps, location far away or "waiting for gps", onstar not working, and "charger door open" notification always on. I have my vehicle currently in the shop at the dealership and awaiting the news. They said their electrical guy is currently out and they are trying to figure out what it is. All forums I have read say it's the telematics module for all except the charger door notification. I hope my car isn't there for days as it has already been there over night

Telematic module? Mine is doing the same thing

Took ours to the dealer on Monday. Needs new telematic module as expected. Was told the car thinks it’s in Michigan. No doubt the default fail stage status. Waiting now on the part. Seems like a fairly prevalent issue.
