Software problems of the 2019 Jeep Wrangler

During software update vehicle quit starting and has not started since.

While driving down a winding mountain road, the "electronic throttle" warning came on as did vsc, abs, check engine and electrical. The steering became very stiff and the throttle uncontrollable. The vehicle was essentially out of control. We took it to a dealer four times, each time it wasn't fixed. The vehicle is currently at a dealer and fca is trying to figure out what is wrong with it. I heard the mechanic say they had others that were doing this. Fca refuses to describe what the problem might be to me because it's proprietary. They essentially want to try stuff, then have me risk my life testing it to see if it works. The photo is the second time it happened, on an interstate going straight. This is a 2019 Wrangler rubicon with 12k miles and completely stock. This is a very dangerous defect and fca doesn't know or doesn't want to say what it is. They sound like they are trying to cover up the problem with some sort of hacked up software fix, but the software has been completely updated. I am worried that someone will be hurt or worse if this happens to them.

As I drove off the lot I noticed the instrument panel had a distortion on it. Dealership was unable to fix (after a software upgrade). More concerning is the car shakes violently when hitting a bump in the road. I took it in 3 times without resolution. Always on the highway, at first at high speeds, now even going below the speed limit. Sometimes it resolves on it's own, but lately I have to slow down or stop to make the shaking stop. (which is very dangerous when driving on a 65mph highway), the steering wheel shakes left to right and is very loose during these times. I feel very unsafe and it feels like the wheels are going to fall off. This is a brand new vehicle. It happened 5 times on a 15 mile trip to work this morning and has been happening since I bought the car in late February 2019.
