Service bulletins for the 2020 Nissan Altima

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.

PC989 2019-20202023-12-08. Service bulletin. STRUCTURE. Active Grille Shutter Emission Warranty Extension Dealer Notification *****Dealer Announcement***** Nissan is committed to providing the highest levels of product quality and customer satisfaction. Therefore, Nissan is extending the emission warranty coverage on the model year 2019-2020 Altima Active Grille Shutter to 15 Years or 150,000 miles, whichever occurs first. All other warranty terms, limitations, and conditions remain unchanged. On affected vehicles, over time, the shaft connecting the grille shutter motor and shutter louvers may become twisted and/or cracked resulting in the shutter remaining in the closed position and illumination of the malfunction indicator light (MIL). This issue will have no effect on vehicle safety or drivability, but the vehicle may experience reduced fuel efficiency. During the limited emission warranty extension period, owners are eligible for free replacement of the Active Grille Shutter if a MIL-On condition occurs with DTC P059F and/or P159F that requires replacement of the grille shutter assembly. Owners of eligible vehicles will receive notification of this limited emission warranty extension during December 2023. ***** What Dealers Should Do ***** 1. Verify if vehicles are eligible for this Warranty Extension using the warranty extension page of Service Comm. 2. If a customer contacts the dealer with an Active Grille Shutter concern in an owned or leased vehicle, dealers should use the ESM to diagnose the root cause of the customer concern and identify the correct repair to resolve the customer concerns. NOTE: Dealers will need to follow the warranty process and obtain pre-approval when the repair cost exceeds a Dealer’s Claims Administration/Authorization Limits (DCAL). 3. The service department should submit the applicable warranty claim for the action performed.

NTB23-0492023-07-11. Service bulletin. ELECTRICAL SYSTEM. 12 VOLT BATTERY TESTING FOR IN-SERVICE VEHICLES SERVICE INFORMATION The following Service Information lists NNA procedural recommendations for establishing good connections while performing 12V battery testing. These recommendations are expected to promote uniformity during the connection process, therefore reducing the number of incorrect “Test with DCA” and “Replace” results. HINT: If 12 volt batteries are allowed to discharge for a prolonged period of time, battery life may be drastically reduced. This condition may lead to premature battery replacement and customer dissatisfaction. IMPORTANT: • CPX-900 is now an accepted testing tool to use along with or in place of the DSS-5000 • CPX-900 operating instructions are found at: https://nissancpx900.midtronics.com/ • DSS-5000 operating instructions are found at: https://nissandss5000.midtronics.com/ • DCA-8000 is now a required testing tool to be used for all warranty replacement decisions. The DCA-8000 is also a more efficient charger than previously available, and will charge any available 12 volt lead acid battery safely and accurately as long as all precautions and inputs are made correctly. The DCA-8000 operating instructions are found at: https://nissandca8000.midtronics.com/
