When I turn the car on by pressing the break and put the shifter into reverse, the backup camera says ‘unavailable’. I can upload a file. The backup camera dsn’t work if you don’t wait a while in the car before putting it in reverse. On the second situation, the blind spot light gs on when there are no cars behind me. One time, when a lane was splitting into 2, I tried to change lanes and the car jerked hard away. It had the blind spot light on but no cars in visible range.
