Radio/tape Cd Player problems of the 2018 Mitsubishi Outlander

On may 1, 2020 I drove about 15 miles from my home to medford, oregon. I made one stop and upon getting back into the vehicle, I could not start or turn off the electrical component of the vehicle. The mainframe kept showing "electrical system service required" I could not lock the vehicle for safety. I could not drive the vehicle as it is its main purpose. I could not turn off the unit which most likely ran the battery down and is most likely dead. It had to be towed to the nearest dealership which cannot access recall information. They want to charge me $150 to diagnose, and cannot perform any recall work. I purchased this car to avoid getting fired from a job that I had to travel an hour each way. Three months later they laid me off. Now the car I purchased is not working. I had contacted the place I bought the car from after I purchased before this happened to get help with the recall which they assured me there was a place locally. Which there is not. The closest place is California or portland. Now that the car is not driveable, I cannot get it to the right dealership to be fixed under warranty. I don't have extra finances to manage this. I am a single parent on unemployment and I need a vehicle to be able to work. This situation is critical and I am very upset and disappointed in the lack of help and support I have received to have a working safe reliable vehicle. Situation: I drove to town. Parked in a parking lot. When I returned to the vehicle. It would not start. Brakes are locked. Stearing wheel locked. Shifter locked. Radio on. Electrical components would not shut off draining the battery. Windows can roll down, but cannot use power locks to lock the vehicle.
