4 Power Train problem

Failure Date: 12/01/2021

On Sunday, October 10th. I arrived at a friends home in charleston s. C. With about 35 miles left on the odometer. In the am I awoke to find only 5 miles left. As I knew that I was 21 miles away from a Tesla supercharger I called for a tow truck, and paid $265 to get taken to the charge site. I hooked up and the car began to charge. When I was close to capacity I disconnected - and the charge dropped to zero. I called Tesla. They sent a tow truck and took me to savannah GA. Tesla (80 miles south. . . . No charge). 7 weeks later - on Dec 1st. . . I got my Tesla back from savannah GA. Tesla. Immediately I got a warning "power reduced - service required". I called and arranged for service (set up for Dec 14. . . Two weeks away). This morning I got a similar message; 'coolant for battery low - service required" (see image, below).
