Service bulletin DOR-K2T5D-01

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

This SKU is a DEF Injector. The customer communication requested return of unsold inventory to inspect the sealing. The injector sealing may have an issue which will cause a slow leak. A slow leak of the DEF Injector can lead to crystal formation which can cause aftertreatment related fault codes and ECU driven engine derating.
