NHTSA Complaint #11619670 — 2015 CHEVROLET SUBURBAN

While driving approximately 70 miles an hour and trying to switch lanes, we got a stabilitrack warning and the car shut off for a second and then came back on. the weather was nice and there was no snow or any other adverse conditions. This happened a couple more times on the ride and then when we tried to turn into a parking spot it shut off completely and we had to restart it. We turned stabilitrack off and the car was ok for a couple of short drives. Then driving late at late and we passed another car the same thing happened. Then when we tried to turn our brights on we got the same message. Then we got a brake assist message and then we got a collision alert. The headlights were flickering the rest of the drive and we couldnt use our brights. We had our 4 children in the car and it was shutting down at high speeds and very scary. I looked up our vin and it said that the recalls had been worked on but I dont remember this being done. This has never happended before this. our car would be available for inspection if needed.
