On several occasions the following warnings will pop up. Service stabilitrack, tighen gas cap, service trailer brake system, automatic collision prep unvailable, and the check engine light will come on. Then the dashboard lights will flicker on/off, the montior will turn black, the doors will unlock and lock. It has happened when I am going 70 mph down the freeway. And on several occassions the car engine will turn off/stall as I am either pulling into an intersection, parking spot or coming to a stop. I will take it to the shop and have the check engine code scanned/turned off and it will be fine for a week and then start again.
