Crankshaft Position Sensor problems of the 2013 Jeep Grand Cherokee

While driving to work one night my Jeep started making a whining sound. I thought it was the heater since it was 12 degrees outside that night. I leave for work, get about 6 miles down the road and my Jeep starts failing. Warning lights, battery, traction control, wipers slowly go across the windshield, lights dimming. I got to a safe spot to pull over but in the process of stopping my vehicle lost all functionaloty (no breaks, power steering, lights, all electronics gone) and couldnt stop. It finally stops and I'm left with a completely dead vehicle. 12am in freezing weather while 5 months pregnant. When my boyfriend arrived to get me, he noticed a strong burning smell coming from under the hood. At this time the vehicle had sat barely out of the road in the dead of night with no hazards possible to allow other drivers to see me. We find out that there is an alternator recall on my Jeep and take it into the dealership as soon as scheduling allowed. Before alternator blew my Jeep had zero issues. They had my vehicle for 4 days and called to say my Jeep was fixed (no loaner car offered). I go up the next day, they replaced the pcm and alternator, they say nothing else. I go to start my Jeep and it cranks for about 30 seconds and starts. Never happened before. I go back inside to the dealer who has said nothing the last 2 days about my vehicle not running properly and they tell me it is my crank shaft position sensor and was not covered under the recall. And they said they couldnt promise the car would make it home and it was my problem. Unhappy with results we call Chrysler and they tell the dealership to fix that. It does not fix the problem. The problems continue and Chrysler is no longer willing to fix obvious damage from their alternator failure frying the electrical system. The dealership also told me to file a "fake" fire claim on my insurance. Still unresolved.
