Service bulletin N232427150
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
Special Coverage: On certain vehicles, the diesel particulate filter (DPF) fuel injector may fail, setting Diagnostic Trouble Code (DTC) P0420 in the Engine Control Module (ECM). If this occurs, the Malfunction Indicator Lamp (Check Engine Light) will illuminate. If the DPF injector is determined to have failed, dealers are to replace the DPF fuel injector. The repairs will be made at no charge to the customer.
