Official summary
Some 2020 F-Super Duty vehicles may exhibit a condition where the turn signals flash faster after removal of the factory pick up box and tail lamps for flatbed installation. Engineering is working to implement a solution for this condition. Advise the customer that a solution through FDRS is expected to be available 27-Apr-2020. Dealers are asked to follow-up with their customers to schedule a service appointment once the solution becomes available. Monitor OASIS for updates.
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
