What 5 owners told NHTSA about the 2019 GMC Savana Cargo G3500

The battery run out of charge. After a battery boost the car turn on and work OK except that the signal lights did not work first, then they turn on by itself. Same thing happened with the warning lights. The AC stopped working, The wipers wash pump does not work, the outside lights do not turn to high and stayed on after the car is turn off. I took my car to the dealer 3 days ago and they are not able to find the issue even though they contacted GMC directly and worked with their technicians.
