My Nissan Leaf high voltage battery has experienced excessive heating due to normal use of the level 3 chargers. Recently the battery tripped a fault sensor due to the expansion of battery cells due to excessive heating, and the vehicle is no longer drivable. They recommend replacing the battery, but refuse to help with the repairs because the vehicle is 3000 miles over the battery warranty. With the latest recall I believe this is unacceptable, and Nissan isn’t even sure they can get a replacement battery. Please help.
