Flaws and Limitations of the 2018 Nissan LEAF Electric Vehicle
The Nissan LEAF is recognized as a pioneering model in the electric vehicle (EV) market, but it has certain shortcomings and limitations that potential buyers should consider before making a purchase. This article delves into the specific issues with the 2018 model, examining the aspects that fall short of expectations and highlighting areas where improvements can be made.
Heat Management and Battery Performance
Thermal Issues in Warm Climates: One of the notable flaws of the 2018 Nissan LEAF is the battery's design, which is air-cooled. This presents challenges in regions with extremely hot climates such as Texas and Nevada. In these areas, the air-cooled battery can become overheated, leading to reduced performance and potentially decreased range. To address this issue, it is recommended to wait for the 2019 model of the Leaf, which features a 60 kWh battery manufactured by LG Chem with an improved thermal management system. Alternatively, potential buyers should consider another electric car model that better suits their specific needs.
Comfort and Convenience Features
Ideally, a modern electric vehicle should offer various features to enhance the driving experience. Unfortunately, the 2018 LEAF falls short in several regards. For instance, all trims lack rear seat heating, which can be a significant disadvantage in colder climates. Another drawback is the bundling of the 120-volt/240-volt EVSE (Electric Vehicle Supply Equipment) into a separate package. This increases costs and decreases convenience.
The inclusion of a standard heat pump is a positive aspect, but it does not come without drawbacks. The absence of windscreen electric defrost/demist functionality means that fog can easily build up during winter, making driving conditions less than ideal. Additionally, due to the limitations of the heat pump and the air conditioning system, it is inefficient to use both at the same time, leading to a wasteful and frustrating driving experience.
Legacy Features and Optimal Charging Options
No Rear Seat Heating: Though the LEAF does include front seat heating, it lacks rear seat heating, which can be a significant limitation for larger families or those who spend a lot of time in cold climates.
Inconvenient Charging Lid: One of the most frustrating aspects of the LEAF is the difficulty in opening the charging lid. Instead of a touch-opening mechanism, a manual button must be pressed.
Outdated Design Elements: The model from 2018 retains an "ON" switch, a feature now found in most modern electric vehicles, which adds to the vehicle's antiquated feel. This feature is unnecessary and inconvenient.
Unlimited Useful Technology: The inclusion of an optical disc drive is another outdated feature that serves no practical purpose in modern vehicles. Similarly, the navigation screen is small and less useful, and the 360-degree camera view is also too tiny to be of much use.
Autopark Interface: The autopark system on the LEAF requires users to activate a button, which is generally acceptable. However, the use of beeping sounds during the process can be disruptive and annoying.
Charging Standard: While the LEAF does support the CHAdeMO charging standard, which offers a maximum charging rate of 75 kW, it does not support the newer CCS (Combined Charging System) standard, which has become the legal standard in the US and EU, providing a 100 kW charging rate. By not supporting CCS, the LEAF appears outdated compared to other modern EVs.
Aesthetics and Reliability: The standard charging cable can pose a risk of scratching the front bumper over time, especially in areas with prolonged exposure. Additionally, the lack of a more robust app to support the vehicle's features can lead to frustration and inconvenience.
Range and Performance
Adequate but Not Exemplary: The range of the 2018 LEAF, while better than some models, is somewhat inadequate compared to other vehicles in the same price range, such as the Chevrolet Bolt. It is slightly behind the Bolt when it comes to efficiency and range, especially in less favorable climates or when carrying passengers and cargo.
Driving Dynamics: The driving dynamics of the LEAF are not as refined as those of vehicles from manufacturers such as Volkswagen and BMW. This can be particularly noticeable in terms of acceleration and handling, with the LEAF often feeling a bit sluggish and less agile.
High-Speed Charging: When it comes to high-speed charging, the LEAF's maximum charging rate of up to 75 kW via CHAdeMO is not as fast as the 100 kW rate provided by the newer CCS standard. Despite the availability of quick charging options, the LEAF does not offer them as standard equipment, except on the highest trim level.
Conclusion
In summary, the 2018 Nissan LEAF, while a significant contribution to the electric vehicle market, has some notable flaws and limitations. These range from thermal management issues to inconvenient features and outdated design elements. Prospective buyers should carefully consider these aspects before opting for the LEAF, especially if they have specific requirements or preferences regarding comfort, convenience, and performance.
