Park assist and backup camera components help drivers see and gauge distance when maneuvering in reverse — ultrasonic sensors detect nearby obstacles and trigger audible warnings, while backup cameras display a live rear view on the dash or infotainment screen. A failing sensor or camera often shows up as constant or false parking alerts, a sensor that stops detecting altogether, or a rearview display that's blank, frozen, or distorted. Browse replacement park assist sensors and backup cameras for cars, trucks, and SUVs to restore reliable visibility and obstacle detection in reverse.
