by Harley-Davidson recalls nearly 90,000 motorcycles due to a dangerous defect
In the modern world of cars and motorcycles, technology has taken over so much that some simple maintenance tasks have become beyond the capability of the average owner. Some cars don’t even have a dipstick to check the oil level. Harley-Davidson hasn’t gone that route yet, but according to a new recall, maybe it should have. The company is recalling 88,039 motorcycles due to a defect that can cause engine oil to spray out when the dipstick is removed. In at least one instance, according to Harley, this issue may have caused an injury.
Which models are affected by the recall
The recall covers a wide range of 2024-2026 model year motorcycles, including several Touring, Road Glide, Street Glide, and Softail models. At the heart of the issue is a component that most owners have probably never heard of — the airbox baseplate. This part is in most cases mounted directly to the V-twin engine and serves several key functions: it holds the air filter and cover in place, directs incoming air to the throttle body, and most importantly, manages crankcase ventilation.
The cause of the defect and injury risk
The recall notice states that a manufacturing defect can block one of the ventilation channels. When this happens, pressure can build up in the engine with nowhere to escape. This is bad for the engine itself, but it also leads to the reason this recall may be linked to injury.
Harley-Davidson reports that it is aware of an incident where a dealership technician was injured after oil sprayed on them while working on a motorcycle with the defect. Removing the dipstick can be similar to shaking a bottle of soda and then unscrewing the cap. The pressure has to go somewhere.
How the company discovered the problem
Notably, Harley had already been looking for this problem. Previous inspections relied on shining a flashlight through the vent opening to make sure it was clear. The problem was that some blockages were thin enough to let light through but still obstructed airflow. The updated inspection process now physically checks the passage of the channel. Harley’s investigation found 192 reports of blocked vents. In fourteen of these, oil was reportedly leaking from the filler neck.
The repair procedure and affected models
The fix itself is relatively simple. Dealerships will inspect the vent hole of the airbox baseplate and repair affected motorcycles if a blockage is found. Harley expects that most motorcycles will only require an inspection, not a part replacement. Owner notification letters were supposed to be sent between May 11 and May 20, and VIN-check availability began on April 30.
List of affected models
This recall is yet another reminder that even seemingly simple mechanical systems can harbor unexpected dangers. While Harley-Davidson is taking steps to correct the situation, the very fact that a simple oil level check procedure can lead to injury is concerning. The story of thin blockages that couldn’t be detected with light shows just how complex diagnosis can be and underscores the importance of physical inspection methods. Owners of affected models should contact their dealers immediately, because although most cases will likely be limited to just an inspection, ignoring the problem could lead not only to engine damage but also to real physical danger.
