2019 Suburban instrument panel not working

[Squishyface]

I have a 2019 Suburban with less than 50k miles that I've owned for 2 weeks...started it up one day, instrument panel not working.  AC blows, bluetooth works, radio works, no gauges working 

Currently at the dealer and they cant figure out what's wrong with it.  Has a warranty. 

Not the computer, not the installed Kahu crap...nothing on the diagnostic tests

 

Any one had this issue?  Suggestions?

Did it get fixed? What was the problem? Same here.

Just had the same thing happen to my 2019 Tahoe.  Dealer currently says "never seen anything likes this before"  not encouraging.  Anyone get theirs fixed?

2019 suburban instrument panel not working.  No gauges working.  Happened on a weekend and I needed the vehicle the next day.  Disconnected battery for 5 minutes and problem has temporarily gone away.

I am having the same issue, going to the dealer on Monday.  Did you figure this out?

I just did this as well, it worked, gauges are all working again, everything fine.  Guess I need to make sure I have a 10 mm wrench and a screwdriver to help get the positive connection off.

Hello, I’m having this same issue. Did disconnecting the battery resolve this issue? Just temporarily?

Here’s a service bulletin for this issue. The serial data gateway module typically needs to be reset (unplug the fuse or possibly unplug the battery) or reprogramming. Below is also a helpful link.

My suburban, however, required a new instrument cluster and serial data gateway module. Both were fried.

Had the same issue (6/14/22) - removed left dash fuse panel. Disconnected all 3 connections to fuse panel - waited 1 minute then reconnected (be careful with the tabs to disconnect) - started it up and all is back to normal.  I think it had to do with a bad iPhone connector in the auxiliary port that it required a reset.  Will only use Apple connectors from now on (just my guess).  Good luck.

Thank you so much B Mac for the direction, you saved me a trip to the dealership. The cause of my issue itnturns out was a loose ground on the battery. Thanks again!

I had the same issue (11/9/2022) - started the car and the dash went limp. This link was extremely helpful (as noted above) and provide the details I needed to diagnose the issue. The problem with the reference material was that the diagrams/documentation for the fuse box didn't match my car.  

 

To fix it, I pulled off the driver side fuse panel. Pinched the white locking mechanisms (highlighted) on each side of the black power block. Once the locking mechanisms were pinched, I was able to pull the white tab which disengaged the power block. I left the power block off for 2 minutes then re-engaged via the white tab.
