Brake Abs Warning Light problems of the 2014 Jeep Cherokee

Two issues with my car, first the transmission failed while driving 70 mph. The car messaged "service transmission immediately" and began to decelerate. I had no control of this process. The abs light came on and luckily I made it off the road. Secondly and independently the brakes make a loud grinding noise when the abs is engaged. The dealer was perplexed by both issues. Cannot tell me what is wrong and assures me my car is acting normally.

The car completely shuts down with no indication or warning while driving, steering wheel locks. Immediately after shutting down the brake (however the gear is in drive) and battery light displays. I take gear out of drive and put it in park, wait a minute or two at times right in the middle of residential street or the end of a turn but it always occur while the car is in motion. I have to crank the ignition several times while tapping down on the gas pedal until the engine starts, hit the brake release, put gear back in drive or at times neutral then back in drive in order to move. This occurrence happened a few times before repairs and about two or three times daily after transmission repairs, and software updates. When pushing down on brakes to make a stop the car will accelerate (as if it's confused whether to stop or go, although I'm pressing the brake to stop) before coming to a complete stop. When backing up or switching gears it's a forceful loud jerk between shifting gears. While driving out of the blue the windshield wipers came on (no rain) and I was not able to disable them . I pulled over on the shoulder and turned the car off waiting a moment before restarting they continued to go back and forth on a dry window they stop on their own about 20 minutes later. Speedometer blanking in and out. Car burning excessive amounts of gas. Prior to engine shut down no indication or warning messages however after repairs of transmission and software updates the engine, throttle, abs lights, and transmission service message appear and disappear simultaneously when the car is running as expected. Tire pressure display inconsistent.
