Service bulletins for the 2017 Infiniti Q50

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.

Engine Control Module (ECM) Reprogram California Voluntary Emission Service Campaign ***** Campaign Summary ***** INFINITI is conducting a Voluntary Emissions Service Campaign on approximately 49,497 specific INFINITI vehicles identified in Service Comm and currently registered to owners in the state of California to reprogram the Engine Control Module (ECM) in the event that a permanent diagnostic trouble code (P-DTC) for P0448, P0101, P2008, or P0087 is recorded in the ECM. Due to calibration errors on the affected vehicles, the ECM may improperly store a permanent diagnostic trouble code (P-DTC) even though the emissions on-board diagnostic system is functioning properly. As of July 1, 2019 the State of California has implemented a revised Inspection Maintenance (I/M) or “Smog Check” test program. Without the software update, the subject vehicles may not pass this Smog Check test in those areas of California where such testing is required under state law. This incident has no effect on the safety, performance, drivability, or fuel consumption of the applicable vehicles. ***** What Retailers Should Do ***** 1.
