Historical MOT pass rates and DVLA records for 2021 model year cars.
- "Rapidgate" (DC Fast Charging Throttling)Moderate
The lack of active liquid thermal management means the battery management system (BMS) aggressively throttles DC rapid charging speeds once cell temperatures rise above approximately 35°C. On consecutive motorway CHAdeMO fast charges in summer weather, charging power automatically steps down from 45kW to 15–20kW, doubling dwell times at service stations.
- 12V Battery "Vampire" DrainModerate
Leaving the Leaf plugged into a home EV charger after charging completes can cause the vehicle control unit to remain awake to maintain NissanConnect app communication. This creates a parasitic load that drains the 12V auxiliary battery, leaving the car unresponsive despite the high-voltage traction pack being fully charged.
- Traction Battery Cell Voltage Imbalance and Weak Cell DegradationSerious
While the ZE1 features an upgraded lithium-ion laminate pack over the ZE0, the lack of active liquid cooling means thermal stress from rapid motorway driving or repeated CHAdeMO fast charging causes individual cells to degrade unevenly. A single weak cell module with a voltage deviation greater than 50mV will cause the BMS to trigger Turtle mode prematurely or cause the state-of-charge percentage to plunge suddenly from 30% to single digits under moderate acceleration.
