Warning problems of the 2019 Subaru Crosstrek

My 2019 Subaru Crosstrek surges at speeds around 60 mph, and swerves the vehicle without my control. I have to hold the steering wheel tightly and steer out of the swerve, which is incredibly dangerous on freeways or mountain roads. Apparently, the lane departure assist is the culprit, so now I have to disable the app before I drive. Why would I allow this dangerous application to drive my car for me? I have barely avoided crashing into semi trucks and driving into road shoulders because of this device. I think the car is dangerous. There is yet another dangerous issue with this car. There is another device that disables the transmission while idling in traffic. The steering and transmission are literally locked in place. I had this happen once in a drive through window, and once on a hill, while traffic was stopped for an accident. When the traffic started to move again, 20 minutes later, I could not get my car to start, and I was in front of a mile long line of traffic, coming back to highway speed, completely stopped. A policeman stopped and knew that there was a little " dimple" on my dashboard that would uncover a locking mechanism. If we only had a slender probe that would fit inside the dimple-pencil too big, so was screwdriver. By this time, I had 2 policemen stopped and traffic whizzing by me. An electrician stopped, knew about the dimple too, and had a slender enough rod to fit into the area, slid the locking mechanism to the side, and started the car again. On both of these issues, I called Subaru customer service and Subaru corporate. Nobody knew what these issues were, never heard of them! the car is inherently dangerous and I am stuck driving it because I financed it only a year ago and can't afford to buy another car. Subaru should at least acknowledge these dangerous issues, and offer me another model without these issues. The 2019 Crosstrek is the model I have that has these dangerous issues. Earlier and later models do not.

The eyesight turned off and would not turn back on. Then the airbag symbol lit up on the dashboard. My cruise control and lane assistance were not working as well. If I had been involved in an accident, the airbags would not have deployed. The warning messages appeared about 3 weeks ago.

Ever since I have owned the car may 2019 I have had the problem of dangerous unstable steering when it automatically departs from lanes at speeds above 50 mph in all weather conditions wet sunny mountains hilly when it puts all us in danger when tha driver has to adjust the car. Twice I have taken to the dealership and no action was taken and we remain apprehensive about driving our less than 6000 miles. It is unsafe and dangerous. Can any thing be done.
