Service bulletin WB15-46

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

On the vehicles affected by this bulletin the EPA (US Environment Protection Agency) decal located in the engine compartment displays incorrect information related to the vehicle emission control. Specifically, the first character, indicating the model year in the vehicle family identification number is incorrect and the California state EPA compliance notice is missing.
