Car Stall problems of the 2016 Buick Verano

Beginning in may, I started noticing odd declines in accelerations, randomly, even when using cruise control. Then, I almost stalled out on the road & lost power steering. This is dangerous & scary. I took it to the dealership & reported a hard shift from 1st to 2nd gear and my radio shutting off randomly, too. After looking over my car, I was told they could not �replicate the issue� of losing power, and that they needed a code or an error message & to bring it back when I had that! I guess, it's ok with gm if I'm in an accident (or die) in the meantime, & I was told that the hard shift is just how the car runs. These answers are unacceptable. If a car is dangerous, you don't send a person back out on the road because you can't �replicate� the issue. Furthermore, a serious hard shift between 1st and 2nd gear is not how a car is made. I believe these are �canned� statements that are used and taught in hopes that the owner will go away�which I did, but shouldn't have. Then in August my car stalled out twice & I lost power steering and could have been in a serious accident. But now, things are even worse. My radio has cut off again, the hard shift is more obvious, and now my passenger seat says there is someone there when they are not, so it beeps at me. The car is possessed. There is no was it should have this many problems at one time. It seems electrical. Dealership has had it for two weeks. I had a message this time; stabilitrak needs serviced. They again said "can't replicate it", but I was not allowing that answer this time. The car is dangerous. Gm has been sued over very similar issue & some are reporting their fix isn't working & still lose power on the highway. Other 2016 gm cars have this issue. I am researching this & it obvious gm has an on-going dangerous issue & is ignoring it again. How many people have to die? NHTSA help!.

Was driving on expressway going 65 when car totally turned off or stalled. It scared the hell out of me. Haven't even made my first car payment yet. Called dealer they wanted me to wait till tomorrow are they kidding. They finally agreed to give me a lender car. Salesman said they have never had any problems with Verano upon checking this morning I have found many years with this problem.
