First, Nissan's more than 23,000 Leaf batteries are at risk of fire during fast charging.
Nissan will reportedly recall 23,887 2019-2020 Leaf vehicles in the United States due to the risk of fire during fast charging. Both the Leaf's 60 kWh and 40 kWh models are affected.
Nissan said there may be excessive lithium deposits in the battery packs of the affected vehicles, which could increase resistance and cause state-of-charge fluctuations. When a vehicle is undergoing Level 3 fast charging, the increased resistance may cause the battery to heat up quickly, increasing the likelihood of a fire. At the same time, the battery packs of the affected models may experience smoke, noise, interruption of charging, or unusual odors when charging.
It is reported that Nissan will soon issue an official notice to owners of the affected models, advising them to avoid using the Level 3 fast charging function until a permanent solution is introduced. Nissan is currently developing a software solution, and its distributors will update the battery software free of charge, with a notice of formal remedies expected in November.
Second, there is a risk of short circuit in the battery modules of Porsche's more than 27,000 Taycans.
Porsche will reportedly recall 27,720 2021-2024 Taycan vehicles in the United States due to the possible risk of short circuits in high-voltage battery modules, which increase the risk of vehicle fire.
It is understood that the affected Taycan models were produced between October 21, 2019 and February 1, 2024, and are equipped with battery packs manufactured by LG Energy Solution in Poland.
Porsche says there is no identification or early warning of the vehicle when a short circuit in the battery pack is about to occur. At the moment, Porsche's measure is to monitor the vehicle's online data and contact the owner if necessary. Before replacing the high-voltage battery pack, Porsche advises these owners to charge their vehicles to 80 percent only. For vehicles for which online data is not available, the dealer will conduct a diagnostic test and, if necessary, replace the battery module assembly free of charge.
Porsche will send a notification letter to dealers on October 16 and to car owners on November 29. The final solution will not be available until the first quarter of 2025.
