SYNC4 touchscreen blackout — a software gremlinmoderate
The most common complaint on the 2021 is the SYNC4 touchscreen going blank or freezing, sometimes taking the backup camera, climate controls, or defroster with it. Ford's service material treats this as an APIM (Accessory Protocol Interface Module — the module behind the screen) software problem and states that replacing the module doesn't resolve it; the fix is software. Still, one owner in the federal file paid $1,500 to replace the computer behind the screen. Several camera recalls (below) address related blank-image faults. If the screen misbehaves on a test drive, this is a known pattern — confirm the latest software update and camera recalls rather than paying for a module.
