Service bulletin NTB24-039

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

***** Campaign Summary ***** Nissan has notified the National Highway Traffic Safety Administration (NHTSA) that it is issuing a Voluntary Safety Recall Campaign on certain 2023 Nissan ARIYA vehicles identified in Service Comm and DBS National Service History. On affected vehicles, the current sensor inside the battery junction box may detect a gap in the current ripple frequency of the motor while operating at high speeds. The misdiagnosis results in the inverter’s Power Electronics Box (PEB) taking a protective measure by cutting the motor’s torque. If this issue occurs, affected vehicles may experience fail-safe mode resulting in a sudden loss of motive power without prior warning, increasing the risk of a crash. In this condition, a malfunction indicator lamp (MIL) and a warning message “EV System OFF” will illuminate on the instrument cluster display. The fail-safe mode is released after the vehicle is completely powered off, allowing for a possible restart. Dealers will inspect affected vehicles and verify whether the vehicle received the inverter software reprogram from campaign R23C6 which improved fail-safe protocols. If campaign R23C6 reprogram was performed, no other action is necessary. If campaign R23C6 reprogram was not performed, the dealer will reprogram the inverter to improve fail-safe protocols. ***** What Dealers Should Do**** 1. Verify if vehicles are affected by this Voluntary Recall using Service Comm or DBS National Service history – Open Campaign I.D. R24A8 2. Dealers must not sell, lease, trade, rent or loan any vehicles in dealer inventory subject to this recall campaign until after the vehicle has been remedied. 3. If a retailed vehicle affected by this Campaign ID visits the dealer for service, the dealer should inform the customer about the recall and communicate that the software update is available.
