Defect: Harley-Davidson Motor Company (Harley-Davidson) is recalling certain 2024-2026 FLTRX, FLHX, 2025-2026 FXBR, FLFB, 2025 FLHXU, 2026 FLTRXL, FLTRT, FLHXL, and FLHLT motorcycles built with an Airbox Baseplate (part number 29000373). The airbox backplate breather port may be blocked, allowing pressure to build up inside the crankcase.
Risk: When the dipstick is removed while the crankcase is pressurized, oil may eject from the fill spout, increasing the risk of injury.
Fix: Dealers will inspect the breather port, and if the port is blocked, repair the blockage, free of charge. Owner notification letters were mailed May 14, 2026. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov April 16, 2025.
