Yesterday (8/8/21) I flew 6 missions created through Dronelink. I was trying to fly an Orbit mission with a fully charged battery. I rcvd. a msg. saying that the mission could not be flown because contact with the aircraft could not be made. I tried re-starting the mission a couple times but it would not work. I started to bring the drone back when I suddenly rcvd. the sound of drone RTH. The problem was my RTH is set to 140 feet and I was at approximately 50 feet alt. and 100 feet away. The drone started to land right where it was, which would be on top of a car. I hit the RTH button to stop descent but it would not stop. I tried taking over the controls and I struggled to keep control of the drone. I was trying to gain altitude and fly back to me in an empty spot of parking lot. I just barely made it back and just missed crashing into a moving car. I tried looking at my flight logs and out of 6 logs 2 could not be read by "Airdata". Also one 12 minute mission created with dronelink was not even recorded. What would caused DJI fly to go into emergency land mode with a fresh battery. Of the flight logs I could read there was only 2 records with a normal landing at 30%?
