I have a 2018 Ram Quad-cab 1500 Hemi. The backup lights and camera sometimes fail to come on when I shift into reverse.. I would say about one time in 20. Shifting back into drive and then into reverse again has no effect.. still not working.. However restarting the engine (ignition off, then "start") always fixes the problem, so I do not think it is a loose connection anywhere. Anyone have any ideas?
