The 2021 Leaf is Nissan's second-gen EV with solid drivetrain reliability but notable suspension wear issues and some battery/charging quirks. Most problems are age-related suspension degradation rather than catastrophic EV failures.
Front Subframe and Bushing Deterioration
Common · medium severity
Typical onset: 60,000-90,000 mi
Symptoms: Clunking over bumps, especially from front end, Steering wander or vague center feel, Accelerated tire wear on inner edges, Visible cracking in subframe bushings during inspection
Fix: Front subframe bushings fail early on these due to battery weight and instant torque stress. Replacement requires dropping subframe (4-6 hours labor). Often find upper control arm bushings also shot during same job, add them while it's apart. OEM bushings preferred over aftermarket for longevity.
Estimated cost: $1,200-2,200
Rear Trailing Arm Bushing Failure
Common · low severity
Typical onset: 70,000-100,000 mi
Symptoms: Rhythmic thumping from rear at highway speeds, Rear end feels loose or unstable during lane changes, Visible bushing separation or tearing on lift
Fix: Rear trailing arm bushings wear prematurely, likely from battery weight distribution. Replace both sides at once (2-3 hours labor). Not safety-critical but affects handling predictability. Some techs press new bushings into existing arms, others replace entire arms depending on corrosion.
Estimated cost: $600-1,000
12V Battery Failures Causing No-Start
Occasional · high severity
Symptoms: Vehicle won't 'ready' even with full traction battery, Intermittent dash warnings about charging system, Dead 12V after sitting 2-3 days, Can't shift out of Park
Fix: The small 12V battery runs all computers and contactors — when it dies, car is totally dead despite full main battery. Nissan's battery management doesn't maintain 12V well during long sits. Replace with quality AGM (0.5 hours labor). Not unique to 2021 but affects all Leafs. Some owners add trickle chargers for long-term parking.
Estimated cost: $250-400
CHAdeMO Rapid Charge Port Communication Errors
Occasional · medium severity
Symptoms: DC fast charging sessions fail to initiate or stop mid-charge, Error messages on charging station screen about handshake failure, Works fine on home L2 charger, Intermittent — may work at some stations, not others
Fix: CHAdeMO port communication board or wiring harness develops corrosion or loose pins, especially in wet climates. Diagnosis requires oscilloscope to check CAN signals (1-2 hours). Fix may be simple pin cleaning or require port assembly replacement (3-4 hours). Nissan TSB addresses some cases with harness replacement.
Estimated cost: $400-1,800
Climate Control Blend Door Actuator Clicking
Occasional · low severity
Typical onset: 50,000-80,000 mi
Symptoms: Loud clicking or grinding from dash when adjusting temperature, Stuck on heat or A/C regardless of setting, Intermittent clicking on startup for 10-15 seconds
Fix: Blend door actuators fail with typical plastic gear wear. Dash removal required for access (4-5 hours labor on Leaf due to tight packaging around EV components). Not urgent but annoying. Replace all three actuators if one fails to avoid repeat dash removal.
Estimated cost: $800-1,400
Front Differential (Reduction Gear) Noise
Rare · medium severity
Typical onset: 100,000+ mi
Symptoms: Whining or humming that increases with speed, Noise present in all driving modes, Vibration through floorboard at highway speeds
Fix: Single-speed reduction gear can develop bearing wear or gear mesh issues at high mileage. Requires removal of entire motor/transaxle assembly (6-8 hours labor). Nissan often recommends full unit replacement rather than internal rebuild. Rare but expensive when it happens.
Estimated cost: $3,500-5,500
ProPILOT Camera Misalignment After Windshield Replacement
Occasional · low severity
Symptoms: ProPILOT Assist unavailable warning after windshield work, Lane departure warnings not functioning, Forward emergency braking disabled message
Fix: Front camera behind mirror requires precise aim calibration after any windshield replacement. Many glass shops don't have Nissan ADAS calibration tools. Requires static targets and Consult III (1.5-2 hours). Not a failure per se, but common headache. Verify glass shop capability before windshield work.
Estimated cost: $200-400
Owner tips
Inspect front subframe bushings at every alignment — catch them before they destroy inner tie rods and ball joints
Keep 12V battery on maintainer if parking more than a week; saves expensive tows
Check CHAdeMO port pins for corrosion every 6 months if you fast-charge regularly, especially in salt states
Budget for suspension refresh at 60-70k miles — the battery weight accelerates wear significantly compared to gas Nissans
Solid used EV buy if suspension has been addressed and battery health is good (check capacity bars); avoid high-mileage examples without service records showing subframe work.
