When vehicle does automatic software updates from gm, it "blows up" the personalization menu. i am in physical therapy now from car seat that automatically went to position 1 when i opened car door. easy exit had been turned on by update. i had it turned off because it never worked right with memory seats. now after another update and menu was skewed again. easy exit turned back on as well as seat heaters on start up. both had been turned off in menu.
