Driver Alerts have suddenly started changing from beeps to seat vibration

Steve C said:

Suddenly my 2022 GMC Yukon Denali has developed a mind of its own and changes the driver alert "beeps" to "seat vibration". I go into settings and change the alerts back to beeps and this lasts for a few days and then the next time I drive I notice I am getting Seat vibrations instead of beeps. Anybody else with this problem or know how to correct this?

2023 GMC Yukon Denali - Beeps reverts to vibration almost daily. Have been unable to figure out a pattern or induce “flip” with same shutdown/startup procedure.

Is it a programming error, forcing a reset or is it intentional? In this day of corporate legal concern, maybe GMC firmware guys have been instructed to program vibration as a default to protect users that mistakenly or unknowingly set beeps by mistake!
Just throwing that out there!
Footnote on 2023 GMC Yukon Denali: Both keyfobs were programmed with exact setting, except seat position.

Steve C… did you ever get this fixed? My 2023 Tahoe is doing the same thing.

I sent a certified letter to GMC customer support and they actually called me; only to say take it to the local dealer for analysis. I did that and left it with them for tw days. They could not reproduce the issue but discovered that one of the key sets was programmed to "vibrate". I have not used that key set since I bought the vehicle so I don't think that was it. They reprogrammed it to "beeps". I picked up my vehicle and it has done the same thing 3 times in 10 days. No particular patter as to how many starts and stops or distance or time driven. GMC has been in contact with me since and said they will discuss with service manager of local dealer. Waiting to hear back.
