that's why we'll all end up leasing or download an app to borrow a truck from the GM dealer on a daily basis.  once your done with truck at the end of the work day leave it on street in front of your house and a fresh vehicle will be waiting for you in the morning..  soon  you will own nothing : )

This weekend I changed the touch screen on my 2017 GMC Denali, no more issues with changing channels, flipping to maps, annoying, clicking sound. Total time 1.5 HRs, total cost $35.79. Much better tha

After having a serious issue for a year and a half with my radio changing stations on its own, and reading this thread, I did the following:

1.  Replaced the shark fin with a new one for $65.00.  Did not fix the problem.

2.  Had my HMI module software updated at the dealer's for $60.00.  Did not fix the problem.

3.  Ordered a used display off of ebay for $200.00.  Took less than 10 minutes to remove the old one and plug up the new one.  Fixed the problem.

 

If you plan on doing this beware of the 7" screen vs. the 8" screen situation.  My original was an 8" screen so there was a little gnashing of teeth when trying to match up the exact same thing.

Like others here, my 2018 suffered from the same actions. Following another member's lead, I removed the touch screen from the dash and disconnected the digitizer ribbon cable (brown) from the PC board. This identified the screen  as the problem and eliminated the annoying and constant changing of both the touch screen and the DIC screen. I can still access most (if not all) of the screen via the radio control knob (right) and the steering wheel controls. This works fine for my use and I'm in no hurry to spend any money. Not a workaround for everybody but it was quick, free and works.

I have the same problem with my 2015 Silverado. I was hoping to see someone had a fix for it but unfortunately it looks as though I will have to deal with it. Dealer tried everything from software updates to replacement parts till they told me they could replace the screen. I don’t see how that could fix anything as how can a replacement radio fix the instrument cluster screen from changing from speedometer to radio. I think it’s a bug in the computer that they don’t know or care to fix.

I had the same problem with my 2018 GMC Canyon, and it was indeed the screen.  After watching enough youtube videos on removing/installation, I ordered a replacement screen from a supplier in China.  I first removed the screen and retrieved the exact part # from the back.  A quick google and it came up with a supplier on AliExpress.  The seller had both new and used, and I went with new, and he/she was quick to respond to any questions I had.  Yes, it's a China supplier, but the process was smooth, and I got the replacement screen in about 10 days (they quote a month) via US Mail.  I paid with PayPal, and AliExpress has feature that requests you confirm receipt in good condition before they release funds to the seller.  Installation was quick (I had been through the removal and reinstall of the old screen before), and all issues went away (2 months now).  My total costs were about $210 for the screen shipped, and about $8 for some plastic tools from Amazon designed for working on modern vehicle interiors (basically plastic pry tools).  The new screen is noticeably brighter and crisper than the old one, and all issues are gone.  I'm tempted buy another as back up should this one fail in a few years.  All in all, I believe my 2 year trip through this ordeal is over.

I replied to a similar post on here about this same problem I'm having with my 2017 Silverado at 38K miles.

Yes I think it's the display. Can be just needs cleaning on the contacts or it's just bad.

  This just started a week ago. I will not take it to the stealership. I figure it out myself.

  I'm done with GM and their cornies.

Bought my truck two weeks ago and this happened on the test drive, I recorded a video and showed it to the salesman. Sales manager stepped in and wrote up a contract that they would fix or replace until issue resolved, hopeless screen replacement will fix!

The digitizer on the screen is the failed part. You can replace the screen (has the digitizer attached) or do what I did and disconnect the cable from the screen pc board. Your screen will look fine but you will no longer have "touch" ability. All functions (well most all) can then be accessed via the controls on either the radio or the steering wheel.

Here's the vid on removing the screen (and other things).

This vid shows the touch screen removal.

You then want to unlatch the tan/gold ribbon cable and secure it. You do not need to actually disassemble the screen. The ribbon cable powers the digitizer. Plug in your wire connectors and power up the unit to check that the screen lights up but of course you will have no touch capability. reverse the steps from the first vid and you're done.

In the 2nd video where he removes the cables for the screen, could you identify which TAN/GOLD ribbon cable to remove? the 1st one he does or the 2nd one?

Into the second vid, at the 40 second mark, you will notice two ribbon cables visible. The smaller tan/light/brown/gold on the right is the digitizer ribbon cable you need to disengage.

 

Note that after he removes the cover to the pc board/screen he rotates the screen and removes the large ribbon cable on top. This is not the correct cable. The second cable is the correct one. Again you do not need to remove the screen. Just secure the cable so as not to damage/short the pc board when re-installing the cover.

Yes, I had a service appointment today; the advisor told me that the technician found that the display needs replacement. They will call and schedule an installation appointment when they receive the new unit. I thought it was the IO5 HMI module itself or wire connection. They tried updates for the HMI, to no avail.  It must be something physically wrong with the touch screen display. I’ve seen YouTube videos that show touching the “blue” button on the mirror and another that shows pulling the 20 amp radio fuse, wait 10 seconds and re-insert the fuse to reset the radio. Search YouTube for that. It didn’t work in my case. Good Luck. 

The blue light on the mirror is for onstage

      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

      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.

      By bluev8 · Posted

      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?

      I went to the county a few years back to dispute my property taxes. To do that I hired an appraiser and a lawyer. The County Assessor wished to argue that the homes in my neighborhood the appraiser used were all 'distressed properties" and not representative of the "Market Average".    My response was," Of the 50 homes in our subdivision 43 of them were "distressed properties" under bank foreclosure and as such "Distressed IS the market". Lawyer about choked on his coffee and handed the Assessor the 'receipts'.    I won that case on the evidence provided by the Lawyer and the Appraiser.    We have the same thing going on here. My statements were based on the GOVERNMENTS NATIONAL DATA and yours on local markets in areas of your interest. They are both correct....   Thing is, this divergence was based on NATIONAL and not on LOCAL. I think you even understand that. But like you said, we are both stubborn and hardheaded.    I do not see any advantage to disengagement.  But that said we can step back to compose ourselves.
