Just got a message to update the software on the car regarding the transmission control unit and check engine light. Anyone else get the update request and install it yet??? Any issues installing it???

 

I got it this morning and installed - no problem.

 

I got it too..Solves a transmission issue...

 

What transmission issue?

 

What are the dates of your builds or VIN numbers (last 5 digits) ?

 

Friday the 13th Software Update...

Per the GM Authority (not associated with GM in any way) article:

 

I have no idea how any updates will get to my car. It's not on WiFi and I don't have OnStar activated. Do I go to the dealer to get updates?

 

Got my update installed today. Build date 02/10/20, VIN 0428.

 

Drove my car for a few hours today and didn’t get anything.

Tried to check for updates at home, but got a message about connected services/Wifi not being connected, but then says no updates.

I know for sure it’s on wifi, any tips for getting it to download? Do they stage these updates in chunks so every car doesn’t get it at once?

 

When you have your car parked in garage, you can connect your car to your home's wifi network... If you don't have a home wifi network you can connect to, turn on your cellphone hotspot, and connect your car to that. If your cell phone doesn't have a data plan, drive to a nearby Starbucks and try to steal their free wifi while you sitting in their parking lot

 

This is all wrong.

No WiFi is involved in OTA updates. Neither is an OnStar sub required.

GM communicates with our cars via "connected services" which utilizes cellular tech. They push updates OTA to anywhere there is cell reception.

Not proven, but it is thought GM does updates in batches of VIN's. So just be patient if you haven't got a notification yet.

 

I have it on wifi. That part is easy enough.

what is the wifi used for then?

 

Zymurgy...8/17/20....last 4 of VIN:7931...

 

oops!...07931...

 

There's a variety of apps that can be downloaded to the car - Spotify for instance.

And any apps that have been downloaded will need updates sometimes.

 

got it. Anyways, #8195 still no update.

is it normal though for the update screen to fail with a connection error instead of just saying no update?

 

Zymurgy. Mine is 02330. Drove today and did not receive an update.

 

Yes, that is what it does when there are no updates. Confusing - yes. Could it be better - definitely.
