Dang! I just bought a 2020 Silverado LT LTZ (LAST WEEK) and the day after I bought it the info-tainment system was black screen when i started the truck.  I noticed that the OnStart light is Red.   Drove home in silence.   Next day, display worked just fine.  OnStar light is green.  I found out that the reason OnStar light goes Red is that it cannot communicate with the head unit.   At first i thought it had something to do with ApplePlay or USB.  However,  this even happens when i don't have anything plugged in, and leave my phone at home.   You know right away that its going to happen when you open the door to the truck, as you don't see the bow-tie logo animation.    Took it to the dealership and they seemed to know nothing about it, and couldn't find any recalls, etc.      They scheduled me to get a replacement head unit, but its on back-order and can't give me a date.   Given that I only have like 500 miles on it, and have only had it a week... i am thinking of going back and  asking for my $$ back.    Especially given the long history of this thread.    The only thing that gives me hope is that last post where he had the "poor connection at the high speed LAN terminal".

Just had the same issue today for the first time.

 

2020 LTZ 1500 with 7500 miles,

 

Started the truck and the radio came on but the screen was black, tried restarting the truck and the screen remained black and the radio stopped working.  Drove for about 15 minutes and both came back on.

2019 Sliverado 79,300 miles.  Radio screen sometimes doesn't come on, maybe once a week.  Today it went dark and would not come on.  When I opened the drivers door and turned off truck the screen appeared for a second or two then faded to dark.  Dealer (service) said it might be sleeping.  Turn truck off for 15-20 minutes.  Working now but no confidence.  Backup camera continued to work.

Been dealing with this issue since week two of owning the truck.  2020 GMC AT4, 6.2.  Nice truck but I am getting frustrated with it.  

Apparently there is now a class action suit arising out of the middle district of Florida.  May be worthwhile keeping an eye on this one.  

Truck has been with dealer for 2 days.  I picked it up tonight...they told me a video module in back of the rear seat needs replacement and they've ordered it.  But who knows when it will be in.  In the meantime, rebooting and freezing up is the order of the day.  This video module is what another member on page 9 makes reference to.  According to his dealer, his got wet due to the broken or cracked window frame.  (I called the dealer as he suggested).  My dealer told me that this module handles a whole lot of wonderful things that can go wrong.

My infotainment system is malfunctioning in a different manner. First time, the backup cam would not turn off. Message said take to dealer. Dealer said can’t do anything til they see it happen. This week, 250 miles from home, the screen split in 3 section. The left section shifted to center screen, the remaining screen split in half to either side of that. At the bottom third of the screen I have code.

I also took a video. Dealer still said they can’t do anything til they see it. Thanks be, Ohio’s lemon laws for safety. Stranded me in Cincinnati without GPS.

My husband and I just bought 2 different Chevrolet vehicles. 2020 Silverado and a 2020 traverse. The black screen seems to be still an issue after reading all these posts! My husband has had his radio fully replaced and still has he same issue occurring. This is extremely disappointing as we were being told to stay away from Chevy!

Hi, today morning I went to work, everything’s working as it should, stopped to fill up real quick, starting my truck, Chevy logo appears as usual, but this time it went on for about 30 seconds, then screen goes blank, the only time screen works is when I switch to reverse, apparently screen didn’t burn out, any of the infotainment controls are working, by the way my 2020 Silverado has only 7k miles on it, this should not happen regardless of the mileage, let alone so early in truck’s life, if anyone knows what’s going on, please share, thanks

Mine is a 2019 1500 WT Crew Cab. It has randomly occurred since before its first oil change at 5,000 miles then until now 15,000s. My dealer already replaced the unit but still happening. Dealer said nothing they can do. So embarrassed when it happens with others in my truck. My daughter says "Oh dad, the radio is working! Impressive."

Has anyone paid attention to possible triggers that lead to the head unit not functioning? For example I have a 2020 Sierra 1500 Denali and when my screen goes out I get a black screen with a red triangle with a red exclamation point inside of it which is an Android OS crash icon. I noticed this weekend that every time my head unit crashes the first indicator will be that the Denali logo which normally flashes when I unlock my truck and the dash display turns on, it doesn't come on, the dash display turns on but with just a black screen where it would normally show the Denali logo then it will load the gauges and the head unit will show me the red icon over the black screen. 

 

Does anyone know how the dash start up is connected to the head unit? It seems as if the bug is a software/firmware bug that crashes upon startup of the OS or it could possible be driven by a bad shut down sequence when we turned the car off that leads to an unrecoverable crash that take a while to reset. On my truck the head unit will come back after I drive around for a bit and shut the truck down and let all systems shut down completely before I turn it back on. Today was the first day where I started measuring distance traveled and time elapsed between crashes and being able to recover. The only time it crashed today it recovered after 23 miles traveled in about 30 minutes. I did check at mile 3 and about 10 minutes of travel time to see if that was enough time to recover and it hadn't so next time it crashes I'll record the same distance and time to see if we can zero in on the recovery time. Wonder if we can find out what the denali dashboard logo and OS starting up sequence ties into the head unit.

      2027 GMC Sierra: Official Discussion

      By tararebecca · Posted

      I agree, simplicity and reliability matter more as vehicles get more complicated. A V8 work truck option with fewer electronic features and a stronger warranty would definitely appeal to a lot of buyers who use their trucks for real work. Customizing it with trusted outfitters is often the best way to get exactly what you need.webcrimsNY

      2026 Sierra 1500 Denali - Sound upgrade?

      By artistemorbidity · Posted

      I’ve heard similar complaints from newer vehicles where the factory “premium” systems don’t always live up to expectations. A good installer should be able to improve the sound without turning it into a bass-heavy setup. I’d look into upgrading the front speakers, adding a quality DSP amplifier, and possibly improving sound deadening first—those changes usually make a much bigger difference than just adding a subwoofer. Hopefully someone local can recommend a reputable installer in the Las Vegas/St. George area.

      Do you remember that Harley Davidson was more successful (solvent) when it produced about 60% of the market demand (by design) and forced wait times of up to three years? Even when your turn came around it was, "Take what we are giving you or move to the back of the line and start over". HUGE markup's were 'normalized' and dealer killed. 40% markup and no floor plan? What's not to love? Greed will kill them yet. They have surplus production and customer base is tanking. And still they think nosebleed pricing will work.

      The engine was done as part of the 6.2 recall?   You'd have to see if your VIN also has the 6.2 engine special coverage on it.  Coverage number is N252494003.  If you have this, your engine is covered under this and NOT the GM replacement part engine warranty which is 3yr/100k from the date of install.  The 3yr/100k mi warranty is in effect for non warranty purchases.     This is not any different if it was replaced under warranty without a recall or special coverage.  So if you had a 5.3 and it popped at 3 years in at 50,000mi during the 5yr/60k powertrain, the replacement engine would not get the 3yr/100k, and instead gets the remainder of the 5yr/60k as coverage.     So N252494003 gives 10 years or 150,000mi of coverage, which ever comes first, starting at the vehicle in service date.  So if your in service date is 01/01/2022, N252494003 gives you special coverage of the engine until 01/01/2032 or 150,000mi, whichever comes first.  So if your start date was 01/01/2022, you'd have left 5 years and 4 months (lets round to august 1st), or 62,000mi left of coverage.   So you need to know your in service date to know how much coverage is left.

      Injector update

      By CamGTP · Posted

      Okiee dokie there bud, way to take things to the extreme.   I guess you missed the whole point and take things way to serious. I installed different EV6 style injectors that just so happen to be larger in my car running the same LQ4 engine and with a better spray pattern than the stock style injectors and I noticed no difference in the idle quality. Kinda was my round about way of saying that even if you put the same size but better style injectors in your truck, you will likely see the same thing.    I'm sure you're great to have conversations with in person if that's how you act through a keyboard. One little things sets you off and now I guess my dick is all up in your face.
