NHTSA Complaint #11620215 — 2019 NISSAN LEAF

Received a notification from Nissan Corporation that my 2019 Leaf is the subject of a safety recall concerning risk of lithium ion battery fire during Level 3 charging. The notice explains that the vehicle's lithium-ion battery may experience "excessive lithium deposits within certain battery cells which could increase electrical resistance and result in a fluctuation in the state of the charge." The notice explicitly cites that the battery may contain excessive lithium deposits but the potential remedy (it has not been issued yet) relates only to a softwear update to prevent rapid heating of the battery. However, there is no remedy planned or addressed to the problem of "excessive lithium deposits" which increase electrical resistance and the impact of that damage to the battery life, performance, deterioration or efficiency. The NHTSA report actually cites specific batteries installed in the Leaf model years implicated in the resulting safety recall. It is essential that NHTSA evaluate the impact of these batteries, the effect of excessive lithium deposits on the car's general safety and performance and the necessity of requiring full replacement of batteries damaged by this defect. The issue of damaged batteries is inextricably related to the safety recall and fire risk. As the problem of damaged batteries is confirmed by Nissan Corporation's Recall Notice and cited in the Defect Information Report filed by Nissan with NHTSA (which reference the specific battery components involved), these defective batteries should be subject to replacement.
