EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL
Nissan North America, Inc. (Nissan) is recalling certain 2018-2023 LEAF vehicles. The Owner's Manual instructions for defroster operation are incorrect, and may result in reduced defroster performance under specific conditions. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 103, "Windshield Defrosting and Defogging Systems."
VEHICLE SPEED CONTROL
Nissan North America, Inc. (Nissan) is recalling certain 2018-2023 LEAF vehicles. The vehicle may accelerate unintentionally if the driving mode is changed ("D" to "B"; e-Pedal "On"; or "ECO" mode) after disengaging the cruise control.

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.
NHTSA recall 25V655 and Nissan campaign R25C8 apply to 19,077 model-year 2021-2022 LEAF vehicles equipped with a Level 3 CHAdeMO quick-charge port. Excessive lithium deposits inside battery cells can increase electrical resistance and cause rapid heating during Level 3 charging;… Severity: high.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA
Nissan North America, Inc. (Nissan) is recalling certain 2018-2022 LEAF vehicles. Damage to the camera harness can cause distortion or loss of the rearview camera display image. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."
SERVICE BRAKES, HYDRAULIC:FOUNDATION COMPONENTS:HOSES, LINES/PIPING, AND FITTINGS
Nissan North America, Inc. (Nissan) is recalling certain 2023 LEAF vehicles. The right-hand brake tubes may have been damaged during production and could corrode, possibly causing a hole in the brake line and a brake fluid leak.

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.
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.
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.
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.
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.
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.
