Just got my 2020 denali duramax a few months ago, 8k miles on it so far.  I pay 25 dollars a month for the unlimited data plan, but my data is not working.  The truck is broadcasting it's hot spot.  and I can connect to it's hot spot from my phone, and it works just fine.  But with any data going through the actual dashboard of the truck itself, it doesn't work.  Apps won't download, spotify doesn't work, I cant even see the anything in the "manage plans" under the mygmc app.  This just started all of a sudden out of nowhere a few nights ago at about midnight.

 

I've talked to onstar about it and have tried doing factory reset on the dashboard, and a few other things they had me try.  The said they will have to escalate it to tier 2 offline software support  and I would hear something back within 5 business days.  Kind of frustrating because the legit only reason I bought the 25 dollar unlimited data was to listen to spotify through my truck and not use my phone's data.  So I'm kind of paying everyday for the unlimited data for nothing.

 

Has anyone heard of this or have any ideas what's going on?  Or ideas of things to try?  I can connect to a different wifi hot spot with my truck such as my home wifi and everything works great when I'm on that.

I have a 2020 2500 LTZ and I am having the same exact problem. Talked to the onstar and they told me the same thing. It has done this before but not for this long. It has been going on for about 2 days. I wish someone would tell me what I am doing wrong?!

Forget the truck's WiFi on your phone, then search and again and connect back to it. That helps sometimes. Don't just disconnect from it, delete it/forget it on phone, then reconnect.

Did you ever get this resolved? I'm having the same issue and cannot enable "Share Hotspot Data" setting in wifi settings

I had a similar issue. Could not join the WiFi network. Called OnStar a talked with a tech. Tried numerous attempts to diagnose the issue. Multiple resets etc. He was stumped for a bit as to why he could not resolve the issue. On a whim he decided to have me delete the network from my phone. He then remotely changed the network password and had me join the network using the new password. Bingo! It worked. No issues since.

I just started having this exact problem with my 2020 silverado. Problem started out the blue. On star has tried numerous restarts, and now it is in line for the offline tech support...no idea why it started. I will try doing the phone thing... any other help would be appreciated.. thanks

I have a 2020 Silverado Z71 2500HD Diesel with 23K I have a similar issue with the internet connection. When I remote start the truck the internet is not active. Shut it off open the door wait a minute then start normally the internet works fine. This just started happening a few months ago. There have been no updates to the system that I am aware of. Just asking to see if anyone else noticed this problem. I plan on asking the dealer with my next service.

This happens to my 2020 1500 LT LM2, but seems to only happen when I remote start the truck.  I've talked with Onstar on several occasions, but they don't seem to have a permanent fix asside from turning off the truck, open/close the door, lock the truck using the key fob and wait for 2 minutes to restart.  Comes back on every time.  Crazy that this bug still exists...

      2023 DRW Wheel Liners

      Did have to make 1 modification because of the WeatherTech rear mud flaps and that was needing 3 longer screws than what came with the install package. 😄

      Picked up the liners yesterday. Installed passenger side WITHOUT any modifications. All mounting holes lined up perfectly. Rain is interfering today with drivers side. Very Happy! Will add pics when finished

      OCI, not when but why?

      As a matter of amusement I’ll leave this conversation with this. Do you beat the government average fuel estimate? Statistics are a guide to me. Not a rule. Someone once said I have to have the last word. If true and possible may be. I’ll blame that on working in a family business.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By bluev8 · Posted

      That is a fair point, and I agree that trying to log “everything in the truck” would be the wrong direction.   There are a lot of modules and a lot of traffic. If the product became a full-truck datalogger, the amount of data would get huge very quickly, and most owners would never use it.   I think the first useful version would need to be narrow: - powertrain-side event evidence - selected high-value parameters - communication / voltage / reset events - pre/post event window - short report first, raw log only as backup   One distinction I should make is between active OBD/PID polling and passive bus capture. If you are polling PIDs through OBD, then yes: the more parameters you request, the lower the effective sample rate becomes, and you are adding diagnostic traffic to a vehicle that is already busy running itself. With passive CAN capture, the recorder is not asking all the modules for data. It is listening to traffic that is already on the bus. So it does not consume vehicle bus bandwidth in the same way that a scan tool polling hundreds of PIDs would. But your point still applies in a different way.   Even if passive capture does not add bus traffic, the recorder still has limits: - processing rate - storage rate - timestamp accuracy - decoder workload - event filtering - report size - user attention span   So the answer cannot be “log everything and let the user figure it out.” The product would need to store enough raw evidence to be useful, but only decode, graph, and present the important parts around the event.   A practical report should probably show: - what triggered the capture - how much pre/post data was preserved - which selected parameters changed - how those values compared to baseline - whether the same pattern happened before - whether any voltage, reset, bus-off, lost-message, or communication fault occurred - selected graphs around the event - raw data only as supporting evidence   So I agree with you. More data is not automatically better. The real product is the reduction from raw data into a useful event report.

      That makes sense, and I agree with most of that.   I think the product would need both: 1. a default powertrain template, so it is useful out of the box; 2. user-selected priority parameters, so the owner or shop can choose what they want to see first.   Different users are going to care about different things. One owner may care about oil pressure and voltage. Another may care about misfire trend, AFM/DFM behavior, or U-codes. A shop may want communication events and repeatability first. Your baseline point is probably the most important one. Raw data is not very useful unless the report can show what normal looked like for that vehicle under similar conditions.   The way I would think about it is: - start with a basic known-good baseline - learn normal behavior for that specific vehicle over time - allow the event to be overlaid against baseline - show whether the event was a one-time spike or a repeatable pattern - provide a simple severity level, but with clear limits on what that severity means   For example, early severity could be something like: - Info: event captured, no obvious abnormal pattern - Watch: value moved outside baseline, but not repeated - Warning: repeatable abnormal pattern under similar conditions - Critical: communication loss, voltage drop, bus-off, reset, or severe repeated event   I would not want the first version to say “replace this part.” That would be overclaiming unless there is repair-confirmed data behind it. It would be more honest to say “this pattern deserves inspection.”   On the OBD port question, I think OBD absolutely has a role. OBD is probably the right place for: - DTCs - freeze frame - VIN - calibration information - normal scan-tool parameters - Mode 6 / enhanced diagnostic data if available The reason I am still looking at an ECM-side recorder is that the failure may happen before anyone connects a scan tool. If the owner plugs in a scanner after the event, the pre-event evidence may already be gone unless the ECU happened to save it. So I do not see this as “OBD versus ECM-side.” I see it more like: - ECM-side recorder: always armed, rolling buffer, event evidence - OBD/DLC companion: DTCs, freeze frame, VIN, calibration, normal scan data - phone/cloud: status, notes, upload, report generation, notifications   I agree that phone connection and push notifications would be useful. I just would not want the phone or cloud connection to be required for capture. The recorder should save the event locally even if the phone is not connected. The phone should help with event marking, download, notes, upload, alerts, and report viewing.   For a default GM V8 event report, would this list make sense? - RPM - calculated load / MAP - throttle position - vehicle speed - gear / torque converter state if available - coolant temperature - oil pressure - oil temperature if available - battery voltage - commanded AFM/DFM state if available - actual AFM/DFM state if available - misfire counters / roughness by cylinder if available - fuel trims - relevant U-codes / communication events - bus-off / lost periodic message / module reset / voltage drop events Which of those would you remove, and what would you add?
