The 2018 Leaf is Nissan's second-generation EV with a 40 kWh battery pack. While the electric drivetrain itself is fairly bulletproof, this platform suffers from premature suspension wear, weak AC components, and some frustrating software/camera glitches that trigger recalls.
Front Subframe and Bushing Deterioration
Common · high severity
Typical onset: 50,000-80,000 mi
Symptoms: Clunking or knocking over bumps, especially when turning, Steering wander or vague feel at highway speeds, Visible cracking or tearing of rubber subframe bushings during inspection, Tire wear on inside edges from misalignment
Fix: Front subframe bushings fail early due to the battery weight distribution. Requires lowering the subframe (4-6 hours labor), replacing all four bushings, and a four-wheel alignment. Some techs replace the entire subframe assembly if bolt holes are wallowed out. This is a known weak point on the ZE1 chassis.
Estimated cost: $1,200-2,400
Front Control Arm Bushing and Ball Joint Wear
Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Popping or creaking when going over speed bumps, Excessive play in front wheels during shake test, Front-end shimmy or vibration during braking, Failed state inspection due to loose ball joints
Fix: Both upper and lower control arm bushings wear faster than expected, often needing replacement along with ball joints. Upper arms are 2 hours each side, lowers are 1.5 hours each. Most shops recommend doing all four arms if one is bad since labor overlaps. Alignment required after.
Estimated cost: $800-1,600
AC System Failures (Condenser, Hoses, TXV)
Occasional · medium severity
Typical onset: 40,000-70,000 mi
Symptoms: AC blows warm or intermittent cooling, Visible refrigerant oil stains on condenser or hose fittings, Hissing sound from dash when AC is on (TXV failure), Low refrigerant pressure on gauge test
Fix: The AC condenser is mounted low and vulnerable to road debris punctures. Hose assemblies crack at crimp points. The thermal expansion valve (TXV) sticks or fails internally. Condenser replacement is 3-4 hours (bumper removal), TXV is 5-6 hours (dash work), hoses are 2-3 hours. R-1234yf refrigerant is expensive.
Estimated cost: $1,000-2,200
ABS Pump/Module Failure
Occasional · high severity
Typical onset: 60,000-100,000 mi
Symptoms: ABS warning light and traction control light both illuminated, Loss of regenerative braking feel, Hard pedal or reduced braking assist, Codes C1130, C1145, or U1000 stored
Fix: The integrated ABS pump and brake booster unit can fail, often from internal valve body corrosion or pump motor issues. This is a complete module replacement (2-3 hours labor) plus bleeding and calibration. Nissan-only part, no aftermarket availability. Critical safety item—don't drive with ABS light on as regen braking is compromised.
Estimated cost: $2,000-3,500
Backup Camera Failures and Recall Issues
Occasional · low severity
Symptoms: Intermittent or blank backup camera screen, Camera image freezes when shifting to reverse, Camera works only after multiple ignition cycles, NHTSA recall notices for camera software updates
Fix: Two separate NHTSA recalls address camera system failures where the display doesn't activate in reverse. Software updates resolve some cases (1 hour at dealer), but hardware camera failures require liftgate trim removal and camera replacement (1.5-2 hours). Dealer-only repair for recall work, but aftermarket cameras can be retrofitted.
Estimated cost: $400-800
12-Volt Auxiliary Battery Premature Failure
Common · medium severity
Typical onset: 30,000-50,000 mi
Symptoms: Car won't go into ready mode even with main battery charged, Clicking from under hood when pressing start button, Loss of all accessory power and lights, Low voltage warnings on dash before complete failure
Fix: The small 12V battery (located in the rear cargo area on 2018s) powers all computers and relays. These fail every 3-4 years regardless of mileage due to heat and charging cycles. Replacement is straightforward (0.5 hours), but the Group 51R battery is dealer-priced unless you source aftermarket. Many owners don't realize an EV still has a conventional starter battery.
Estimated cost: $200-400
Owner tips
Inspect front subframe bushings and control arms at every tire rotation—catching them early saves alignment headaches
The 12V battery is hidden in the cargo area; test voltage annually and replace proactively at 3-4 years
AC system uses expensive R-1234yf refrigerant; fix leaks immediately rather than topping off repeatedly
Nissan's battery warranty is 8 years/100k miles for capacity loss below 9 bars; document any drops on the dash gauge
Solid EV drivetrain with predictable suspension wear issues—budget $2,000-3,000 for front-end refresh if buying over 60k miles, otherwise a smart used buy for city driving.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA · 24V071000
2024-02-02
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."
Consequence: A rearview camera that does not properly display an image can reduce the driver's rear view, increasing the risk of a crash.
Remedy: Dealers will inspect the rearview camera and harness for damage and replace them as necessary. If no damage is found, the dealer will apply protective tape and reroute the rearview camera harness. Repairs will be performed free of charge. Owner notification letters were mailed August 9, 2024. Owners may contact Nissan customer service at 1-800-867-7669. Nissan's number for this recall is R23D7.
VEHICLE SPEED CONTROL · 23V494000
2023-07-17
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.
Consequence: Unintentional acceleration can increase the risk of a crash.
Remedy: Dealers will reprogram the vehicle control module (VCM), free of charge. Owner notification letters are expected to be mailed August 30, 2023. Owners may contact Nissan's customer service at 1-800-867-7669. Nissan's number for this recall is R23A6.
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."
Consequence: Reduced defroster performance can limit visibility out of the windshield, increasing the risk of a crash.
Remedy: Nissan will mail an addendum with updated instructions on how to operate the defroster, free of charge. Owner notification letters are expected to be mailed April 1, 2023. Owners may contact Nissan's customer service at 1-800-867-7669. Nissan's number for this recall is R22C5.
BACK OVER PREVENTION: SENSING SYSTEM: CAMERA · 19V654000
2019-09-12
Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Consequence: The lack of an image in the back-up camera display increases the risk of a crash.
Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.
