What is the 2011-2023 Nissan Leaf Battery Pack Capacity Degradation?
The Nissan Leaf uses an air-cooled lithium-ion battery that degrades faster than liquid-cooled competitors. Hot climates (Arizona, Texas) accelerate degradation significantly. Early models (2011-2015) with 24 kWh packs can lose 30-40% capacity within 5-7 years. Nissan provides an… Repairs typically run $0-$8,000. Severity: high.
What is the 2011-2019 Nissan Leaf Intelligent Brake Unit (Electric Brake Actuator) Failure?
The Leaf uses an electric motor-driven 'Intelligent' brake booster/master-cylinder actuator (part of the brake-by-wire regen system) rather than a conventional vacuum booster. The actuator relies on a capacitor bank energized by the 12V supply to drive the master cylinder quickly… Repairs typically run $500-$3,900. Severity: high.
What is the 2011-2024 Nissan Leaf 12V Auxiliary Battery Drain and Failure?
The Leaf's small 12V auxiliary battery drains and fails frequently, sometimes within 2-3 years. The telematics system, Carwings/NissanConnect, and other modules draw power even when the car is off. If the 12V dies, the car cannot be turned on despite the traction battery being fu… Repairs typically run $100-$200. Severity: medium.
What is the 2018-2022 Nissan Leaf Rapidgate: DC Fast-Charge Throttling from Battery Overheating?
The 40 kWh (and to a lesser extent 62 kWh) Leaf uses a passively air-cooled battery with no liquid thermal management. During consecutive DC fast-charge (CHAdeMO) sessions on a road trip, the pack heats up and the BMS aggressively throttles charge rate to protect the cells. A fir… Repairs typically run $0-$150. Severity: medium.
What is the 2011-2022 Nissan Leaf CHAdeMO Quick-Charge Port Failure / Won't Fast Charge?
Owners report the CHAdeMO DC fast-charge port failing to initiate a session, stopping mid-charge, or the connector locking/not releasing. Root causes include corrosion in the gray control connector on the back of the Power Distribution Module (PDM) where AC/DC charge command line… Repairs typically run $200-$1,200. Severity: medium.
What is the 2011-2024 Nissan Leaf Reduction Gear Oil Seal Leak and Gearbox Whine?
The Leaf's single-speed reduction gearbox is filled with a small amount of Nissan Matic S ATF (~1.4-1.5 qt). Nissan lists the fluid as fill-for-life, but owners report oil-seal weeping and, in some cases, premature gear wear. A developing whine/growl that rises with speed is ofte… Repairs typically run $60-$2,500. Severity: medium.
What is the 2011-2025 Nissan Leaf Rear Brake Caliper Seizing and Rotor Corrosion from Regen/e-Pedal?
Because regenerative braking (especially in B-mode/e-Pedal) does most of the deceleration, the rear friction brakes are rarely used and almost never heat-cycle. Without heat to burn off moisture, the rear rotors rust and the caliper slide pins and pistons seize. This leads to une… Repairs typically run $150-$900. Severity: medium.
What is the 2011-2019 Nissan Leaf Dashboard Flame-Retardant Coating Rub-Off and Thin Exterior Paint?
Two cosmetic durability complaints recur on the Leaf. First, the dark upper-dashboard surface is a flame-retardant coating (not paint) that rubs or wipes off — often when owners clean oily fingerprints with soap and water — leaving discolored patches. Second, the Leaf is widely n… Repairs typically run $0-$500. Severity: low.
What is the 2011-2022 Nissan Leaf Premature Front Tire Wear (Low-Pressure Spec / Alignment)?
Leaf owners widely report front tires wearing out prematurely — some as early as 20,000-26,000 miles on the OEM low-rolling-resistance Bridgestone Ecopia tires. Contributing factors: the Leaf's high curb weight (~3,300 lb from the battery) loading the front FWD tires, Nissan's fa… Repairs typically run $100-$800. Severity: low.
What is the 2011-2019 Nissan Leaf 3G Telematics Control Unit (TCU) Shutdown / Loss of NissanConnect?
Pre-2020 Leafs use a 3G-based Telematics Control Unit for NissanConnect EV/Services (remote climate preheat, charge status, charge timers). AT&T shut down its 3G network in February 2022 and Nissan ended NissanConnect app support for Leafs built before 2020 on March 30, 2026, so… Repairs typically run $0-$800. Severity: low.
