# Service bulletin B26\-025

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 \- The factory fuel fill pipe assembly may not have been manufactured to specification. As a result, small contamination particles inside the fuel fill neck may prevent the primary shut\-off valve flap seal from sealing properly. This may result in a fuel smell from the fuel fill neck area and may cause DTC P0455 or P0456 \(EVAP system leak detected\) to be set.
