The official notice
Defect
On certain trucks, water could leak into the connector for the tailgate top camera. Over time, this could cause the tailgate park assist sensor interface module (TPASIM) to corrode. If this happens, the rearview camera image may not display correctly or at all. Note: This problem could cause a "Reverse Brake Assist Unavailable" message to display in the instrument panel.
Safety Risk
A rearview camera image that doesn't display correctly could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.
Remedy
Ford will notify owners by mail and advise you to take your truck to a dealership to inspect and, if necessary, replace the tailgate top camera, wiring harness and TPASIM. The dealer will also update the image processing module software.
