Radio/tape Cd Player problems of the 2018 Jeep Cherokee

Vehicle stopping and shutting off completely while driving (in motion) each and every time on four different occasions. First time it shut off, dealership said it was due to oil change. Second time dealership said a recall on the shift gear in which I wasn't notified about the recall. Third time it shut off, dealership says its an oil leakage. Fourth time it stopped, dealership says it needs a new engine. Chrysler refuses to fix it. The last time I took it to the dealership, Chrysler response was take it home and drive it again and bring it back if it shuts off and maybe then we will fix it. I had to have it towed in the last time due to it not starting and smoking in the tail pipe. On two occasions, the radio cut off completely, screen just went black. My car is now at the dealership waiting on approval from Chrysler to get fixed. This Jeep is very unsafe, dangerous,and a safety hazard for my son and I. It has put me and my sons life in danger on four different occasions. I am terrified to drive this vehicle even if they can fix it because its not a guarantee that I will not have these issues again and next time it could cost us our lives.
