Adaptive Equipment problems of the 2012 Buick Lacrosse

2012 Buick lacross with less than 45k, the car has not started for 3 days and car will finally start after the key is left in the ingition for about a minute then the interior lights and screen come on (appearing as though the car was just charged) the car has had limited steering control the "power steering service soon" light appears a long with another warning light that says '' roll drivers window up, then down" the windows will not roll down neither do the locks work in the car. I was driving down the road and had to pull off to the side while all this was taking place. I have contacted gm for 2 days now,a gm rep named "rupert" took the initial call and said " don't worry, it's all covered gm will take care of it" ( these calls are recorded. ) I made it to a friends house enough to get gm to call roadside assistance and take my car to the dealer, rupert said that it would be best to take my car to the dealer I bought it from. 22 miles away. 8:30 am was when the call was initated and a call from gm roadside assist was made to me at 9:30am with a 2h eta. The first tow truck broke down and I had to call roadside assistance back once the first tow truck did not show up 30 min past the given eta. Finally the second tow truck arrives at 1310 and takes my car to the dealership. I call the dealership to discuss the rental car promised by gm, the dealership says that gm only covers a rental for 3 days, but it will be at the minimum 7 days before my car is even looked at, so I have to pay out of pocket for a rental car for 4 days until my car is even looked at, thats not including the time to fix the problem if it can be fixed right away. After speaking to 6 tier 2 reps specialist and managers I have no answers with a broken car, a rental that is half the size as my lacross and I still have to pay for the rental. Lucky I did not die driving! this needs to be addressed!.

Un smooth shifting around 30 mph ,causing the car to jerk or brake feels like the assist is not sensing ,causing the had to dealership nothing they can do all check out but the problem is still there.
