Rear camera and cross traffic warning system malfunctions randomly, working less than half the time. When the vehicle is put in reverse the system and camera often do not work and issue a notice that it needs serviced. On several occasions it did not warn me of a person behind my vehicle or another vehicle behind me. I have avoided accidents but the system is not working. I have been reading about it and it is common among this vehicle, many complaining that this is the worst rear collision camera on a car. The screen is just black, sometimes with grid lines and sometimes without. On the rare occasion the camera turns on the grid lines often disappear although they are not turned off.
