Service bulletin DOR-G9Z8V-12

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

This SKU is a Fuel Pump Driver Module. The customer communication requested return of unsold inventory to inspect the software. The software may have a fault where the readiness monitors are stuck in the not-ready or incomplete position. The readiness monitors will not cause performance or emissions issues but will prevent the emissions scanning tools from confirming the module is performing correctly, causing the vehicle to fail state required emissions tests.
