Got this email the other day for my 2018 Rogue Hybrid. Looks like its only for CA resident, though I'm in VA.

Model Year: 2018
Make: Nissan
Model: Rogue
Vehicle Identification Number (VIN): XXXXXXXXXXXXXXXXX
Dear Howard

Nissan is committed to providing the highest levels of product quality and client satisfaction. Nissan is contacting you regarding an available software update for the Engine Control Module (ECM) in your vehicle. This update is available to you, free of charge.

Reason for Customer Service Initiative

On some 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. Only vehicles registered in the State of California are currently required to complete this revised I/M testing. In the future, if you attempt to register your vehicle in the state of California without first receiving the software update, your vehicle may not pass this Smog Check test.

This incident has no effect on the safety, performance, drivability, emissions, or fuel consumption of your vehicle.

What You Should Do

No action is required for vehicles registered outside of California – you do not need to visit your Nissan dealer to receive the software update.

However, if you wish to receive the ECM software update, contact your Nissan dealer at your convenience in order to arrange an appointment and reference Technical Service Bulletin NTB19-045. The update will be available free-of-charge under normal 8Y/80K mile ECM warranty. If you move to California and require the software update after the warranty period expires, you will be eligible for reimbursement.

Please bring this notice with you when you arrive for your service appointment.

If you have further questions, you may contact the Nissan Consumer Affairs Department. The toll free number 1-800-867-7669.

Thank you for providing us an opportunity to ensure on-going satisfaction with your Nissan vehicle.
