Service bulletin CSA-036
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
Faulty DEF sensors that due to shortage were not replaced. Instead engine software was temporarily modified to account for continued operation with a faulty sensor until replacement sensors were available. This campaign will install an engine control module calibration as well as confirm and/or install a new DEF header.
The document
The document is the manufacturer's. This site does not hold it. NHTSA files a document at one of these two addresses; we have not asked NHTSA which.
