NEED HELP Unusual Problem with Data Center

[RedEnvoyDenali]

I have a 2006 Envoy Denali with many miles on it that i just love. When i purchased it in 2008 and for many years every time i started it the data center display would should standard stuff like "ICE" (i live in Canada), "Curbview" in reverse and those type of messages. Lately whenever i start it the Odometer mileage shows up and I need to press the top button 4 times to get it to disappear. Not a major problem but i know how to get it if i need it and it is just annoying. I have been told that this is normal however for 16 years i got no response when starting and now it appears that my computer is starting to function as it should. Question is how to I convince the computer to return to previous "No Display" mode when starting. Thanks in advance for any thoughts on this minor problem.

Strange. It should default to whatever the last display was before shutdown. Maybe age is starting to affect it. Is the button working as it should? I know on mine, the blank display is followed by the odometer. Maybe a button is sticking and when you start, it takes it as a button press. Apart from the button on the steering, there's the button in the cluster that does the same thing. Maybe it's sticking. Or maybe there's a solder joint or something shorting in the cluster.

FWIW... I Copy-Pasted your entire Post #1 and dropped it over on my Off Line (NO INTERNET CONNECTION ) Nomic *GPT4ALL* LLM AI (Large Language Model) using the Llama 3.1 8 Billion Token Model with the 128KB Prompt Window. THIS is what *IT* suggested investigating:

Please note that any time Aging Instrument Panel Clusters are involved and they were assembled using Non-Lead (pB) Solder and the element Tin dominates in the solder alloy... over time "Tin Whiskers" 1,000 Xs smaller than a Human Hair... will Grow like a Beard... even with Brand New In Box Modules (BNIB) that are just sitting around on Store Shelves!

These "Tin Whiskers" are HIGHLY CONDUCTIVE AND VERY FLEXIBLE and can propagate in between various points on the Circuit or Logic-Mother Board and allow Electricity to go where it should not be making contacts... evincing weird Module Behavior (See the NASA Power Point linked below covering this issue with an APP Sensor Gas Pedal Module that can lead to accidental WOT Events) and even cause a serious and hard to diagnose Parasitic Drain (Draw) and become a "Battery Killer".

PS... Since @TJBaker57 has done extensive Bench Top Tear-downs of various Modules to edify us on their Electro-Mechanical Properties and FUBAR issues involving IPC and IGN Modules... the attached NASA Report (NASA's Metal Whisker Group) they conducted in this PDF at the request of the NHTSA regarding a "Dangerous APP Module" might prove very interesting to his investigations as well:

Want to thank everyone for their input to my question. The problem is not consistent but occasionally will not display so that is always encouraging. the steering wheel button has been replaced but this problem started long after the replacement. Thanks for the lesson on Tin whiskers however i will not be going into the panel to investigate, sounds like more trouble i could get into. Again it is not something i can't live with but I like things to work as i expect them so that is why it is annoying. Again thanks to everyone for their input.
