Sporadically when driving the car, turning the wheel hard left or right the message will flash "service stabilitrak" while at the same time, the steering wheel position locks, the electronic system in the car shuts off, and no control of the vehicle is available. This lasts for approximately 1-2 seconds before the steering unlocks and vehicle control is restored. Vehicle has been in the service center for over a week now, and the dealer is trying to return the car to me stating "we cannot recreate the issue so we have no fix". we have photo and video of this happening (after I pulled over to take the video in a safe spot). This has happened multiple times with no rhyme or reason.
