Multiple owners have reported the rearview camera failing to display when shifting into reverse, showing a blank/blue/black screen, or appearing only after a long delay. This issue is documented in owner complaints and overlaps with infotainment/display faults, but the safety impact is distinct because the camera is federally required equipment. In some cases the problem is intermittent, making it difficult to reproduce at the dealer.
