Infotainment Screen Camera Buttons all flashing and Inoperative

[NWStever]

Camera views on my 2022 Denali HD with Pro-Trailering option do not change when I press buttons on the infotainment screen for cameras. The buttons all continously flash and it is difficult (repeative pushes needed) to change rear-view camera guidance from normal wide  to hitch line-up  function. I cannot find in several searches any trouble-shooting guidance. Frustrating that I cannot make use of all the claimed GMC Surround Vision capabilities to make towing my travel trailer easier.  Bad or missing modules or poor firmware????

Additional information:  I reliably get a good truck and trailer side view on screen when I use right turn signal.  Use of left turn signal results in a black display screen only.   Other views using display buttons are inoperative.

What happens when you unplug the trailer?

Right turn signal enabled side view no longer is active.  Other than that, no differences.  Camera view buttons still all flash and  can't change camera views.  The problem doesn't seem to be directly related to trailer status.  Will contact my dealer service advisor after return from a current trip to find out if they have been presented with any similar camera issues.

I took it as you had this problem after you trailered up. I  was hoping it would have corrected itself after disconnecting the cord.

 

Maybe try unhooking the negitives off the battery/batteries, for a few minutes.

 

Has this problem been since new, then?

Yeah, with the exception of right turn signal side view when trailering and the reverse backup camera, the remaining  cameras haven't functioned correctly or consistently since delivered new early June this year. The flashing camera view selection buttons really aggravate me. I would think the owner's manual would have some information about such a fault error but nada.   I was OBE in June and wasn't able to properly assess cameras function. The rear view back-up camera worked (most important) and I could by repeated button pushes get a front camera view and so I let  a thorough check-out slide. I test drove a similar 2021 3500 over a year ago and all the cameras worked, with a  nicely intuitive infotainment interface, and the surround vision overhead views were impressive and a big selling point.  Given that my factory order truck was actually built (-light of chip modules) back on 17 Aug 2021 and it was almost a year later before the thing was shipped and delivered to me on 3 Jun 2022. I suspect the truck is still short of functioning chip modules required for correct and  complete camera functionality.  Hopefully the dealer service specialists have been properly trained to use whatever diagnostic tools GM sells the dealer to sort out these types of electronic anomalies.

GMCustomerService -- Will do. Thanks!

Follow-up report.  A shout out and thanks to GMC Customer Service for helping set up a service appointment with my dealer and for also apparently making sure the dealer service department had the proper trouble-shooting information to efficiently identify root cause of my camera system anomaly. The left camera (bottom of driver side trailer mirror) was found to be defective and it was R&R'ed which solved the problem.  Camera system now performs as designed including side views when towing and using turn signal during lane changes.  The "God's Eye Views"  showing vehicle outline and surroundings is a great and useful feature. 

Cheers!
