Ford Expedition intermittent blind spot and cross traffic warning issues causing rear bumper dent on Ford Expedition

Some Ford Expedition owners report experiencing intermittent blind spot and cross traffic warning issues, which may be linked to mud, snow, or ice build-up between the radar sensor and the rear bumper cover, or damage and corrosion to the radar sensor. These issues could necessitate sensor replacement, often requiring the removal of the bumper, and repairs may range in cost from $850 to $2050. Additionally, some owners find that severe weather or blockages can cause the Blind Spot Information System (BLIS) to malfunction. If the warning issues are related to a dent in the rear bumper, addressing the underlying sensor problems is crucial to prevent further damage and ensure that safety features operate correctly. Regular maintenance and cleaning of the sensors are recommended to avoid blockages, and if warnings continue despite these efforts, sensor replacement may be required for a more permanent solution.
