I can see it change to red in the dash so I know it’s identifying the issue. Anything quick that the dealer may not have done. They are a PIA to go badk to … again

You may need to go into vehicle personalization to enable seat shake. I have mine turned off.

thanks, unfortunately, it's on. I also tried "beep" and no beeps. Dealer's response... bring it by... in like a week and leave it with us... again. literally zero effort on their part to diagnose
