Radio/tape Cd Player problems of the 2017 Jeep Grand Cherokee

2017 Jeep Grand Cherokee laredo shuts off while driving. First noticed about a month after driving it. Approx. Mileage about 5,000 on initial complaint; current mileage about 23,000. Vehicle will beep at you and dash will state "vehicle not in park". First time it occurred at night and I lost all exterior lights. Other times when engine shuts off it keeps radio and interior dash lights on. Multiple dealerships state that they cannot recreate the issue and that no codes are being stored. Chrysler hooked up a data recorder to the vehicle and stated nothing out of the ordinary showed up once it happened. Was also told that if vehicle lost all power during the incident, that the data recorder would not reflect those conditions. The company will not replace, repair, or buy back without a diagnosis. Huge safety concern for not only the passengers and driver, but also others on the road. If on a busy street it shuts off with no lights, there will be greater risk of causing an accident at speed. According to dealership reps, looked into push button controller and receiver, auto start/stop feature, key fobs, and engine fuel system. All open recalls have been performed on my Jeep. All recommended factory maintenance has been performed at the dealership. This is not the only issue recorded, but is the most serious due to life safety concerns.
