Official summary
Service Bulletin for Water Leak at the Top of a Cab Door, Cascadia Day Cab with FE13 Roof Fairing. Some Cascadia day cabs with FE13 roof fairings may be more susceptible to water intrusion into the cab at the top of the cab door due to the way the air flows around the FE13 fairing. Water is pushed past the door seals while the vehicle is in motion, possibly resulting in water intrusion.

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.
