I was driving in the highway, at ~70mph with cruise control on when the error popped up. The temp was been 47-52°F. I got a message saying Service High Voltage System. I thought nothing of it and proceeded with rest of my trip. I went to even colder conditions and got down to 28°F at one point. I noticed that in the car, the AC was not working, it was only blowing cold air from outside. Eventually went to charge and and the car refused. I was 70 miles from home but was able to get a tow.
