My 2015 GMC CAYNON  is doing the same thing the Software is whacked out -puts my phone on hold- which could be dangerous if I need to call 911 - puts my phone on mute— switches radio stations - the display— holy cow like it’s possessed - radio display will all of a sudden display all the channels in the little rectangular boxes and/or display a list of channels that constantly move. Turns the radio on or off randomly.  also randomly the navigation screen would display off and on. This should be recalled and replaced

 

mine started about 2 weeks ago but with short trips never bothered me too much however with a 2 plus hour ride yesterday.  All hell broke loose.  

any fix? Thanks so much

I posted this in the troubleshooting area as well but figure it would be seen more here.   So I found this video on YouTube which is the exact same thing my truck is doing. His happened under war

Thanks for the feedback Dem chevy and Jim C. Since my original post in early January I replaced the HMI module and the radio module to the upgraded 2016 modules that includes Apple Car Play and Androi

I'm reading about a lot of owners who have the same or similar problem but haven't read a lot about any fix for it.  My 2017 Sierra Denali has the same phantom application/radio station switching issues but also the touch screen is inoperable so I can no longer control what I see or hear.  To add insult to injury my "Keep your eyes on the road" government warning has now appeared and I cannot remove it - again because the touch screen doesn't work.  Have taken it to the dealer twice  - once to reset it, once to reprogram and update the software.  Now they say the HMI module needs to be replaced - they "think".  For $900 installed.  I'm hesitant because I suspect it could be a physical issue such as the touch screen itself.  Love the truck otherwise but Fords are beginning to look really good to me.

I was one of the earlier posts on this topic.  My '17 Sierra Denali (out of warranty), still has the issue after 4 months although it has settled into the touch screen not responding at all.  Dealer says "They all do it" (comforting to know...).  The dealer said replacing the HMI module fixes the issue 90% of the time.  $900 after installation, tax, etc.  I said what if it doesn't fix it?  She said, it's a chance you have to take.  As I stated previously, I really want to love this truck but after the low speed braking recall (still isn't fixed), transmission chattering (fixed under drivetrain warranty), and this infotainment issue I'm getting worn out.  First American vehicle I've purchased in over 20 years and it hasn't been a good experience.

Maybe a class action lawsuit would change their mind.  Sucks having a 75K truck that you can't reliable use the entertainment system or make calls with out being randomly put on hold.

Hello guys,

 

I have a 2016 Silverado and it's doing what the OP said and I have found a fix for mine. It was scrolling all the stations on the touch screen, changing frequencies randomly, the touch screen wouldn't work & bringing up the audio menu on the DIC. It would malfunction more when the weather was cold but seemed to work better when it was warmer. So right before our freeze here in S. Texas I snapped the cover off and investigated. The first thing I saw after removing the four screws holding the touch screen was four flat white ribbon cables that are pieces of S*#t that I thought they abandoned back in the 90's. These things are famous for bad connections & nobody in their right mind uses them anymore. So I carefully lifted the tabs on the black connectors holding the ribbon cables, took out the ribbon cable and immediately put it back in to reset. I did this on all four white ribbon cables.

When you do this, be ever so careful, insert a small flat head screwdriver on top of the white cable and between the white ribbon cable and the black connector. Twist it a little bit to raise the connector on left side, move to the middle and raise it and then to the end. Once it's open remove the cable, reinsert and snap the black connector back down. AGAIN be very careful as the connectors are very delicate and if you damage them, you're toast. Good luck, it took me about 45 minutes to do this including taking off the trim. Check utube or somewhere to remove the plastic, there are videos all over for that, no tools needed.

Sean, I have the exact same truck as you...2015 Sierra SLT and I'm having the exact issue you had with your radio. I have researched this for several months now. I was told it was a faulty touch screen, a bad circuit board, HMI unit going bad, etc, etc. I hated to spend big bucks chasing this issue. I recently purchased a complete dash cluster from a totaled 2016 Denali for $170. Installed it and it worked great...for 2-3 hours, then the same issue began again. So it took $170 to determine it's not the touch screen and not the circuit board it plugs into. Now I'm wondering if its the HMI unit under the glove box, but those are $700! I hate bring it to the dealer 'cause I know I'd get shafted. I got a quote for an aftermarket system and that's $800+! I believe I'll do the Dealer because if it doesn't work then, they have to figure it out.

I've got a 2015 Sierra.  Same issues.  Bought an HMI and the radio upgrade (Apple car play etc) from WAMS it was a grand total of $1000.00   

Unfortunately the issue remains.  when it happens I shut the truck off and open the driver's door, close it and restart.  This seems to "reset" things but it doesn't last.  It pisses me off so much  Grr.  I took my panel out on top of the dash and chased the "bad ground"  there was none.  I think the issue must be with the blue connector that plugs into the HMI behind the glove box.  If it's bad wiring then I'm not sure what can be done?  There's a whole wire harness that plugs into the HMI.  I've no idea what the other wires go to.  The bad ground near the A pillar is a fools errand though.  Don't bother with that.  It's an issue that GM needs to address but simply will not own up to.  

 

All of that being said I do like the factory stereo upgrade that I got from WAMS  it has apple car play etc and when it's working properly it's great.  

 

If anyone comes up with a true solution PLEASE share it here!!  Besides this issue I love my truck!

2015 Sierra 1500 SLT 64K miles  Not a scratch!  LOL

I have a 2016 Siverado that has the same problems/symptons. Ready to burn the truck down.

I did the "Turn Screen Off' thing in the settings and it works awesome most of the time.

I do it as soon as I turn the key on. Every once in awhile it may turn the screen on showing the selections to turn screen off. Click that to turn it off. Also, seems some bumps will trigger the screen to come back on.

If you turn a knob like the AC temp or whatever you have to push the screen off selection again.

 

But it has made driving the truck great again!

 

:)

 

This would suggest that it is the screen that is the problem?

      Wow I'm in a pickle. (Broke down truck) and a story.

      By Atlas · Posted

      tl; dr I've now reached the 6th floor of hell. I'm chronicling my journey for my morning readers.   Pulling the top of the intake apart was moderately easy but it involved a lot of parts, connections, and minutae. I was preparing for the new fuel lines to arrive ("nut and bolt kit" it's called). The fuel line connections are notched and held in place by the manifold and a metal plate with a T27 screw.   It's on the back of the intake, under the firewall, with little clearance, and two hard metal fuel lines in the way. I was using Franken-tools (weird combinations of 1/4 inch ratchet with/without an extension, with a bit holder for my T27) to get in there. One of my sockets and bits fell off and has yet to emerge on the floor. I lost a second setup and that's when I almost started throwing tools. But that was the point at which I had gotten traction on the Torx head, and it promptly stripped. No more traction.   I started humming "1-877-kars-4-kids" because I was about at that point. You know what? I'm $1500 into this thing and I can make it disappear just as quickly. This isn't fun anymore. I had spent a lot of time already "tidying" around the engine bay: Fixing all the "someone's been here before!" BS. The truck has been exclusively dealer- and shop- serviced and I'm reminded of why I never let other people work on my cars unless absolutely necessary.   Speaking of dealer service. This truck has a 1" stack of records going back to 1995. I put them all in an excel spreadsheet, date/mileage/description.   The CPI spider has been replaced 4 times in 85k miles. The EGR? Another 4. Multiple, multiple O2 sensors. One Cat. 4? Sets of plugs and wires, and I swear half the stack is diagnosis paperwork for "misfire, runs rough, extended crank, dies at stoplights".   GM was producing some proper crap back then. And it was still well within the era of brittle/crappy plastic. (Windows 95 was released the same month this truck was sold new, we HAD the technology!!)   There (was) a plastic shroud around the evaporator core and HVAC fan in the engine bay. I noticed a chunk of it missing so I poked at it some more and it literally shattered. Touched it some more and pieces were crumbling off. Had a good laugh. Clearly whatever plastic garbage they were using had broken down over 30 years and was literally turning to dust. That was a good half hour of using a shop vac to remove the rest of it.   Back to it.   I was going to give up for the evening but then decided I'm already level 10 pissed off at the stripped screw: G* D* it, give me my tools back -- and my JOY. We'll do this the hard way: The whole intake is coming off.   Blazer won Round II. After finally finding and accessing the 12 intake bolts and using a pry bar to unseat it from the heads, it popped loose in an explosion of gunk and grime raining down into open ports. Awesome.   6 times I reminded myself: Be careful of the temperature sender on the front of the intake.   YEAH, I forgot again and snapped it clean off in the removal. Add another $20 to the ever-growing list of new parts this thing is consuming.   The shame is, long before removing the intake, I had changed the oil in prep for Tuesday's momentous fuel line replacement that was going to be the magic fix and I'd have a running Blazer to tool around in this next weekend. The intake removal, including raining gunk, also gushed dirty coolant all over the valley. Of course it did. Welp, there goes another $35.   I now need an intake gasket set, bolt set, coolant temp sensor, another 5 quarts of oil, some RTV. Don't worry, I've already got 3 new jugs of Dexcool and a thermostat waiting. I'll fill it with clean water first to get it running, dump it, and then add the Dex later on in case... well, let's not go there. I'm only tearing this down once, next time the truck is going on Marketplace for FREE.   Oh, and I'm going to need vacuum hose for all the stupid connections placed at the rear of the engine which have since disintegrated. Come on, GM....tell me you don't do that anymore?   Oh, and the ears on the distributor where the cap screws down are both cracked. I mean, why not put a new distributor in it too. You get a distributor, YOU get a distributor, Everyone gets a new distributor!   This truck isn't out of the woods yet...I'm already questioning how much more time I'm willing to sink in.

      Bent valve in 2025 GMC Canyon Denali - Requires engine swap at 14K miles

      By William Aldrich · Posted

      NewDude, thank you for the suggestions!    I did follow up and the dealer indicates he has an open CX case and is working with DPAC (Dealer Parts Assistance Center).   Per the dealer, GM has had a quality spill and is not providing an update for when a replacement engine will be available.

      Poll: Does your truck have the rear window leak?

      By Silver Yeti · Posted

      That's interesting.   There was a factory wire-hole in the back, top of the rear cab, which had a wire for the third brakelight assembly running through it, as well as several holes (10 of them I believe) for all of the studs coming off of the 3rd brakelight assembly itself.   I sealed all of those holes with RTV/silicone as well.   I found it kind of odd, that none of those holes, were sealed with any kind of sealant by the factory - if there was any there, it wasn't very much.   That said, I've been out in heavy rain and have ran the truck through high-pressure car-washes a few times now and she has been 100% water-tight to this point.   I feel very confident in the repair, we'll see how it holds up.

      2024 Silverado 2500 HD with the 6.6 Gas (L8T) Engine

      By Jay-22-2500 · Posted

      I bought a used 2022 2500hd with 6.6L in February. In March took a 2200 mile trip towing our 6500 lb trailer. Changed the oil day before leaving and when we were arriving at our 1st destination, low oil light came on (roughly 1000 miles) it was 2 qts low. Now it towed like a dream, no issue there, and we did go through the mountains of TN, but still, 2 qts! Luckily I did purchase an extended warranty. Brought it to the dealership in April, oil change and consumption test. Brought it back last week, 1300 miles, no towing, and no oil showing on the dipstick. GM is reccomending a new engine (cheaper than them rebuilding), we'll see if the warranty company comes through.
