My 23 Yukon AT4 does the same thing, I change it back to beeps and then no warning back to vibration. It does the same thing on my seat memory sometimes too, super annoying!I had it happen to me once where it changed to seat vibration, once I changed it back to beep sound it has stayed like that now for a couple of months. So I'm hoping it will stay that way,
