USB Ports work...sort of

I have a new to me GMC Canyon All Terrain with the 8 inch premium infotainment system with navigation.  I say new to me because I picked it up from a local dealer with about 5,200 miles on it.  Everything looks and works perfectly except for the USB ports.  There are two just under the SD Card slot for the navigation system.  I use two USB devices at once.  I use my phone where I'm trying out android auto and also a flash drive with all my MP3 files.  Are those ports supposed to be the same i.e. it should matter which one I plug a device into, right?

 

here is whats happening.  When I plug the flash drive with the MP3's into the lower port, it works fine but when I plug it in to the upper port it works for a while but then stops and I get a "device not found" message on the screen.  When I tether my phone (Samsung Galaxy S9+) to the lower port, Android Auto works fine.  But when I plug it in to the upper port it constantly cuts in and out to the point where its unusable.  Its my assumption that I've got a bad USB port? Even though I'm good with gadgets (after 25 years in IT) everything on this truck is new to me.  Any other ideas?

 

And another thing.  Yesterday, a message came up on the screen while I was driving that said "downloading software update" or something like that.  When I got home and turned the truck off, it asked if I wanted to install the update.  I said yes.  But being in IT I like to know what those updates are actually doing.  so far I haven't found any kind of release notes giving me that information.  Anyone know where to find that information?

I'm anxious to hear any responses to this question because I have similar problems with mine ('19 Colorado) I had a '18 Colorado that I traded for my '19 and the firestick I used in worked fine.  It does not in the '19.  Also strange occurrences with the radio happen too, like playing when I first start the truck after I am positive I shut it off entirely when I last parked it.  Also when this happens there is no display on the infotainment screen.  I have not taken it back to a dealership for this problem yet.  TC shudder & door ajar warning -yes.  Good luck with your radio and like I said I hope someone has experience with my issues.

Thanks- Steve

      New Member Just Bought a Vtrux

      Great info here thank you. I just joined, we have a 2014 Silverado truck we bought about 4 years ago with less than 5,000 miles on it. It has approximately 24,000 on it now. It appears to have all the standard issues that people are talking about. Occasional charging problems especially using 110 volt, occasional blinking triangle where nothing will turn on when first starting the truck but it will reset itself if you wait 10 to 15 minutes. Noisy coupler between the flywheel and the generator. Our truck is speed limited to 74 mph, is there any way to change that? The latest issue we have been dealing with is when driving long distance on the highway at full speed the generator does not keep the batteries charged. The meter will go into the yellow/red border Zone for charge status and the yellow triangle will illuminate solid but the generator will not keep the battery charged, not sure why the controller doesn't tell the gas engine to increase RPM to increase generator output it usually stays well below 25 kilowatts even though the battery is discharging and I have to slow down the highway to 45 mph and eventually pull over and let the truck idle to charge the battery so I can continue driving at speed. Has anyone had this issue before or have any idea how to diagnosed it? When via Motors was around it they were very helpful at troubleshooting. This becomes much if the Terrain is hilly and you're towing a small trailer

      Tonneau cover that does not leak water

      By Z45 · Posted

      I have the GMC accessory (REV) cover installed by dealer. Ordered with the truck.  They did a very good install job, can't find a single issue. Some water gets in around the tailgate but no where else.  You can see daylight around the tailgate but that's not the covers fault.  Installation is means everything. Guys at my dealer were seasoned pros, not inexperienced here today good tomorrow types, like many dealers employ for these jobs.   I don't mind paying for a professional job.

      Like others have said, they will all leak. Mainly at the corners.   I have owned several and the best has been my current one. Revolver x4

      LCA bolts

      By calgator73 · Posted

      About 8 months after an alignment job by the dealer I started experiencing a pretty significant clunk in the front end on hard left hand turns usually parking lot speeds almost at lock.  Occasionally get the same on hard rights too.   Discovered that the lower control arm attachment bolts are TTY and only to be used for a single use. And then I found some evidence of a TSB that indicates you can over torque those fasteners to about 130 foot pounds.   Asked a local shop to investigate and they found 3 out of four bolts loose and retorqued.   I've ordered the MOOG    K100421 lower control arm bolt kit that is completely reusable and not TTY.    Is the 80 ft pounds a realistic number?  Anyone have experience with those bolts?

      Brake Bleeding Procedure on 2026 Silverado 2500

      By davester · Posted

      subscribe to alldata.com, that will have gm's brake bleeding procedure.  and what you have to do likely varies, as if you just replaced a caliper and the MC didn't go dry, you most likely can just do a normal bleed on that corner, but if you disconnected lines at the MC or the abs unit, or let the MC run dry while doing work, you'll have to do a more extensive/complicated bleeding procedure.
