It has happened several times, while driving in a parking lot at 10 mph while making a turn the engine shut off, lost steering and brakes and the stabilitrak warning light came on... the engine restarted in about 5 seconds... I contacted Cadillac main office lawanda 855-880-1400 ex 5911833 and sent a email to mary barra CEO... they gave me a case #[xxx] they are aware of the problem and recalled over one million vehicle but my VIN number has not been added yet.. they will not fix it till GM adds my VIN to the national recall #18289... I was told off the record that money trumps consumer safety....they are making us pickup the car with the knowledge by us driving the car could kill someone if we loose steering and brakes while driving... parts of this document have been redacted to protect personally identifiable information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

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.
