A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Service Bulletin M1438: NEUTRAL SWITCH INVENTORY REMOVAL notifies that Harley\-Davidson has determined that a variance in assembly tolerances may affect the functional performance of certain Neutral Switches \(Part No. 33926\-06B\) causing no or inconsistent neutral light illumination while the transmission is in neutral. In an effort to reduce to the potential of repeat issues by the installation of a suspect replacement neutral switch, Harley\-Davidson is requesting that dealers file a Defective Stock \(DFS\) claim on any existing neutral switches with the identification numbers described in Required Dealer Action, and remove the switches from inventory.
