Service bulletins for the 2021 Nissan Leaf

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.

83 on file from NHTSA, as of 2026-10-19.

NTB23-0542023-07-11. Service bulletin. ELECTRICAL SYSTEM. LIB PACK INTERCHANGEABILITY SERVICE INFORMATION 40kWh Lithium-ion Battery (LiB) Packs are now interchangeable between 2018-2023 vehicles. For Example: 2018-2022 LEAF 40kWh LiB packs can be used on 2023 LEAF 40kWh vehicles and 2023 LEAF 40kWh LiB packs can be used on 2018-2022 LEAF vehicles. IMPORTANT: • The LiB modules and the Li-ion Battery Controller (LBC) are not interchangeable between LiB packs. • If a LiB module or the LBC requires replacement, do not look up the part number in EPC using the VIN. Use the installed LiB module or LBC part number to determine the correct LiB module or LBC to order. • Due to MY18-23 LiB pack, LiB module and LBC part numbers being restricted, please follow the existing LEAF Battery Pack pre-authorization process for Powertrain Call Center review.
NTB23-0532023-07-11. Service bulletin. ELECTRICAL SYSTEM. SILICONE-BASED LUBRICANT OR GREASE CAN DAMAGE ELECTRICAL COMPONENTS SERVICE INFORMATION Do not apply Silicone-based lubricants or grease to, or around, any interior electrical components. To avoid the risk of death or severe personal injury, do not directly spray Silicone-based lubricant or grease, or inadvertently overspray Silicone-based lubricant or grease onto any interior electrical components. These types of lubricants can be detrimental to the proper operation of electrical components.
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/
