The Nissan LEAF: A Comprehensive Guide

The Nissan LEAF (Leading Environmentally-friendly Affordable Family car) is a compact five-door hatchback electric car manufactured by Nissan. Introduced in Japan and the United States in December 2010, it was one of the first mass-marketed, all-electric vehicles globally and has played a significant role in popularizing electric cars for everyday use. The LEAF falls into the compact car segment, offering seating for five and a practical hatchback design.

Generations of the Nissan LEAF

First Generation (ZE0/AZE0; 2010-2017)

  • Years: 2010-2017
  • Key Changes:
    • Initial range of approximately 73 miles (EPA).
    • Battery capacity: 24 kWh.
    • Regenerative braking system to recapture energy.
    • Charging times varied based on voltage (Level 1, Level 2, CHAdeMO DC fast charging).
    • Facelift in 2013 (AZE0) introduced minor cosmetic changes and improved battery chemistry for slightly better range retention.
    • The "S", "SV", and "SL" trim levels offered varying levels of equipment.

Second Generation (ZE1; 2018-Present)

  • Years: 2018-Present
  • Key Changes:
    • Completely redesigned exterior and interior.
    • Significantly increased range with an initial 40 kWh battery.
    • ProPILOT Assist, Nissan's advanced driver assistance system, became available.
    • e-Pedal, allowing single-pedal driving, was introduced.
    • LEAF PLUS models (starting in 2019) offered a larger 62 kWh battery and increased power and range.
    • Improved charging times (especially with the 62kWh battery).
    • Android Auto and Apple CarPlay integration became standard.

Reliability & Common Issues

First Generation (2010-2017)

  • Battery Degradation: The biggest concern for first-generation LEAFs, particularly in hot climates. The 24 kWh battery experienced significant capacity loss over time. The number of "bars" on the battery health indicator is critical when evaluating a used first-generation LEAF. Consider a LEAF Spy Pro app to check the SOH (State of Health).
  • Motor and Inverter Issues: Relatively rare, but some owners reported issues with the motor overheating or inverter failures.
  • 12V Battery: Like all cars, the 12V battery can fail, especially if the car is left unused for extended periods.
  • HVAC System: Some reports of issues with the heating and cooling systems.
  • Suspension: The rear suspension can wear over time, leading to a softer ride.

Second Generation (2018-Present)

  • Battery Degradation (40 kWh): While improved over the first generation, the 40 kWh battery in the standard LEAF can still experience degradation, especially in hot climates and with frequent fast charging. It's less pronounced than the first generation, but still a factor.
  • Battery Degradation (62 kWh): The 62 kWh battery in the LEAF PLUS is generally more resilient to degradation than the 40 kWh.
  • Software Glitches: Some owners have reported minor software glitches with the infotainment system and driver assistance features. These are usually resolved with software updates.
  • Charging Port Issues: Rare, but some reports of issues with the CHAdeMO charging port (less common on newer cars as CCS is becoming more prevalent).
  • e-Pedal Adaptation: The e-Pedal requires some getting used to. Some drivers find it intuitive, while others prefer traditional braking.

General Advice: Regardless of the generation, regular maintenance is crucial. Check tire pressure, ensure proper fluid levels (brake fluid, coolant), and keep the car clean. Have the car inspected by a qualified mechanic knowledgeable about electric vehicles before purchasing a used LEAF.

Driving Experience

Pros:

  • Smooth and Quiet Ride: Electric motors provide instant torque and near-silent operation, making for a very pleasant driving experience.
  • Low Running Costs: Electricity is typically cheaper than gasoline, leading to significant savings on fuel. Reduced maintenance (fewer moving parts) also contributes to lower running costs.
  • Regenerative Braking: Extends brake pad life and helps recapture energy, increasing range.
  • Environmentally Friendly: Zero tailpipe emissions contribute to cleaner air.
  • Instant Torque: Provides quick acceleration, especially at lower speeds.

Cons:

  • Range Anxiety: A concern for some drivers, especially with older models and longer commutes. Carefully consider your driving needs and choose a battery size that meets them.
  • Charging Infrastructure: While improving, charging infrastructure is still not as widespread as gas stations. Planning routes and charging stops is important.
  • Charging Time: Charging can take longer than filling up a gas tank, especially with Level 2 charging. DC fast charging is much faster, but not always readily available or cost-effective.
  • Battery Degradation: As mentioned earlier, battery degradation can impact range, particularly in older models.
  • Initial Purchase Price: Electric vehicles typically have a higher initial purchase price than comparable gasoline-powered cars, although government incentives may help offset the cost.

Buying Advice

Years to Look For:

  • 2019 and Newer (LEAF PLUS): The LEAF PLUS with the 62 kWh battery offers significantly improved range and performance, making it a more practical option for many buyers.
  • 2018 (Standard LEAF): If you're on a budget and don't need a long range, the 2018 LEAF with the 40 kWh battery is a good option, but be mindful of potential degradation.
  • 2013-2017 (Facelifted First Generation): If a first-generation LEAF is your only option, prioritize 2013 and newer models due to improved battery chemistry.

Years to Avoid (or be Cautious of):

  • Early First-Generation Models (2011-2012): These models suffered the most from battery degradation. Only consider them if the battery has been recently replaced or if the price is extremely low and you understand the limitations.

Key Considerations:

  • Battery Health: Get the battery health checked by a professional using LEAF Spy Pro or similar tools. Pay close attention to the number of battery bars and the State of Health (SOH).
  • Driving Needs: Assess your daily commute and typical driving habits to determine the range you require.
  • Charging Access: Consider your access to charging at home and at work. A Level 2 charger at home is highly recommended.
  • Maintenance Records: Review the car's maintenance records to ensure it has been properly serviced.
  • Test Drive: Take the car for a thorough test drive to assess its performance, handling, and comfort. Test the e-Pedal to see if it fits your driving style.
  • Total Cost of Ownership: Factor in the cost of electricity, maintenance, insurance, and potential battery replacement when comparing the LEAF to other cars.

By carefully considering these factors, you can make an informed decision and find the perfect Nissan LEAF to suit your needs and budget.
