2018 Nissan Leaf Fuel System Problems

When I was drivimg on the highway, the battery rapidly plummeted from 50% to 5%. The car urged me to pull over. After pulling over, the battery rose back up to 50%. If I had not pulled over, the car would have entered "turtle mode," which limits the motor's power and can reduce the car's top speed to below 20mph. These low speeds are especially dangerous on interstate highways and could pose a crash risk.

While driving on the highway with a full battery charge, the vehicle battery was suddenly depleted, the car entered "turtle mode" (a reduced motor power at low charge feature), and then turned off completely moments later. This is a huge safety issue as it leaves you to coast to a stop without the benefit of power brakes or steering. This is caused by a weak cell in the high voltage battery, an issue Nissan is aware of but has chosen not to address. Currently I have no other option but to continue driving the car as is, with the risk of an accident in a situation like this continually increasing.
