Service bulletin 14 TS- 13REV

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

"Major fuel system damage can occur when DEF is introduced into the fuel system. A no-start condition, engine overspeed, or engine ran backwards complaints can all be caused by DEF in the fuel system. Likewise, DEF system damage can occur when diesel fuel is introduced into the DEF system. DEF quality fault codes (SPN 3364) and NOx conversion fault codes (SPN 4364) can be caused by diesel fuel in the DEF system."
