Kia Sorento erratic rear camera functionality with stable guide lines on Kia Sorento

Some Kia Sorento owners report experiencing erratic rear camera functionality, including issues such as distortion, a black screen, or moisture intrusion into the camera assembly. These problems may also manifest as missing parking guide lines or a black AVN screen, which could indicate a malfunction in the AVN system or a related harness issue rather than a defect in the rearview camera itself. Additionally, if the AVN system appears to be functioning correctly, owners are advised to check the rearview camera wiring harness for any pinched or damaged wires. In cases where stable guide lines are present but functionality remains erratic, it is recommended to inspect the camera assembly, AVN system, and wiring harness for potential issues. If the problem continues, seeking professional inspection and repair is advisable to ensure the rear camera operates properly.
