Hello, I have a 2018 JEEP WRANGLER UNLIMITED SPORT JL WITH stinger Heigh10 Radio

I remember earlier my display was stating that the Jeep battery was charging for start and stop so I assumed it was stating that I needed to drive more until it had sufficient charge to stop and start , A week or month later I don’t remember exactly I was driving on the highway , my Jeep went into the stop mode and when I was trying to start, it lite up like a complete Christmas tree, locked up and could not start. Even the emergency blinkers weren't' working. I am getting a series of lights in the cluster again. Happens every day almost and began about a weeks ago. Lights that are coming on are the ABS, ESC, Serv 4x4, Sway Bar disconnect unavailable, Stop/Start unavailable, TPMS unavailable, Service Air Bag System and "No Bus" appears in the cluster. Check Engine light comes on as well, and if the vehicle is moving, the speedometer goes to zero and shows blank on the digital screen. Also, the jeep will not shut off when this is happening, push and hold the ignition button will eventually kill the engine but only goes to accessory mode. Took a while before starting again and when it does can’t put it into gears, so I have to wait another 5 to 10 minutes to start it again and finally got it into gear, so I drive it home and within the first day everything was still happening. After cycling through all the errors and disconnecting the battery, it starts and drives again with no lights or issues until it happens again.

I took it to two dealerships for a period of 8 times and they still can't find out what is wrong with the Jeep

here what they did
