2018 NISSAN LEAF

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

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

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

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

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

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
