Due to a manufacturing issue, which has since been corrected, certain LEAF vehicle's lithium-ion battery bonding plates may not meet Nissan internal standards for corrosion resistance. The plates may corrode and in some areas where road salt is extensively used, could break. In rare cases, during vehicle servicing, if both plates break, the battery cover plate is removed and the vehicle is left in READY mode, a technician could be exposed to electric shock if all EV servicing instructions are not followed. Although no such incidents have been reported to Nissan, this voluntary service campaign is being conducted as a preventative measure out of an abundance of caution.
