Harley-Davidson is initiating a recall of 88,039 motorcycles due to a safety defect that results in oil being expelled from the engine fill spout when the dipstick is removed, thereby posing a burn hazard and risk of injury to individuals nearby.
The National Highway Traffic Safety Administration has received the recall notice, which includes specific motorcycles from the 2024, 2025, and 2026 model years that feature a particular airbox baseplate function.
As part of the recall, authorised Harley-Davidson dealers will examine the breather port on the motorcycles affected.
Should the port be found obstructed, the dealer will carry out the necessary repairs at no expense to the owner. Harley-Davidson plans to start sending notification letters to the impacted owners on May 11, 2026.
Which models are included in the recall?
The nine models included in the recall are the Road Glide (FLTRX) and Street Glide (FLHX), which are affected for model years 2024 through 2026. The Breakout (FXBR) and Fat Boy (FLFB) are also included for the 2025 and 2026 model years.
The Street Glide Ultra (FLHXU) is affected only for the year 2025. Additionally, five models exclusive to the 2026 model year are included: the Road Glide Limited (FLTRXL), Road Glide 3 (FLTRT), Street Glide Limited (FLHXL), and Heritage Classic (FLHLT).
All affected units were manufactured with the airbox baseplate part number 29000373.
The NHTSA estimates that roughly 0.4% of the recalled motorcycles possess the defect.
However, owners of all listed models should have their motorcycles inspected, as there is no reliable method to identify a blocked breather port without a thorough examination.
The issue arises from the airbox baseplate, a component located within the engine’s air intake system. In the affected units, the breather port in the baseplate may become blocked.
This port is intended to release pressure that builds up naturally within the crankcase during engine operation. When the port is blocked, the pressure has no escape route.
