Rear-visibility cameras have been required on new US vehicles since May 2018. If the picture suddenly looks cloudy, check the tiny exterior lens first: road spray and fingerprints are common, and a gentle wipe with a clean microfiber cloth often restores the view.

Why the picture goes cloudy

The backup camera’s lens sits in the single dirtiest spot on the car — low at the back, where road spray, salt, dust, and exhaust film collect on every drive. Most “failing” cameras are just dirty lenses. The rest usually have moisture inside the lens, or wiring that flexes at the trunk hinge until it breaks.

What to do, step by step

1. Find the lens: usually just above the license plate, or tucked into the trunk handle or badge.
2. Wipe it gently with a clean, damp microfiber cloth. Never scrub it dry — grit drags like sandpaper and scratches the coating.
3. Still hazy? Look for fog that wiping cannot remove: that is condensation inside the lens. It often clears after a dry day; fog that never leaves means the seal has failed.
4. If the image flipped or lost its guide lines right after a battery change, check the camera settings in the car’s menu before assuming the camera died.
5. No picture at all? A likely culprit is the wiring where it bends at the trunk or hatch hinge — a shop can test that quickly.
