The 2016 Leaf is a solid first-generation EV with decent reliability, but battery degradation is the elephant in the room—expect 20-40% capacity loss by now. High-voltage component failures are rare but expensive when they happen.
Battery Capacity Degradation (Excessive)
Common · high severity
Typical onset: 60,000-100,000 mi or 7-8 years regardless of miles
Symptoms: Range drops below 50-60 miles on full charge (originally 84-107 mi), Capacity bars on dash drop to 8 or fewer (started with 12), Rapid charge rate slows significantly, Battery struggles in extreme heat or cold climates
Fix: Battery replacement requires 6-8 hours labor plus expensive pack ($8,500-14,000 for remanufactured). No practical repair option for individual cells. Heat-climate cars (Arizona, Texas) degrade fastest due to passive cooling design—no active thermal management.
Estimated cost: $9,500-16,000
Onboard Charger (OBC) Failure
Occasional · high severity
Typical onset: 70,000-120,000 mi
Symptoms: Car won't charge on Level 1 or Level 2 (home/public AC charging), Charging fault light illuminated, DC fast charging still works (uses different hardware), No communication with EVSE, or charging starts then immediately stops
Fix: OBC is located under hood near firewall. Replacement requires 3-4 hours labor. Common failure point is capacitor bank or control board. Must be programmed to VIN after installation.
Estimated cost: $1,800-2,800
12V Auxiliary Battery Failure (Premature)
Common · medium severity
Typical onset: 40,000-70,000 mi or 4-5 years
Symptoms: Car completely dead, won't power on despite full traction battery, Accessories work but 'READY' light won't illuminate, Random electrical gremlins, display glitches, Clicking from under hood when attempting to start
Fix: Standard 12V lead-acid battery in engine bay powers all accessories and computer systems. Leafs are hard on these batteries. Replacement takes 0.5 hours. OEM-spec battery recommended—cheap replacements fail quickly.
Estimated cost: $250-400
Electric Drive Motor Inverter Degradation
Rare · high severity
Typical onset: 100,000-150,000 mi
Symptoms: Reduced power output, sluggish acceleration, Warning lights: EV system fault, turtle mode, Grinding or whining noise during acceleration, Car enters limp mode or won't move
Fix: Inverter converts DC from battery to AC for motor. Failure usually means IGBT module or control board death. Located in motor compartment. Requires 5-7 hours labor for R&R. Nissan often replaces entire motor/inverter assembly.
Estimated cost: $4,000-7,500
Charge Port Door Actuator Failure
Occasional · low severity
Typical onset: 50,000-90,000 mi
Symptoms: Charge port door won't open electrically, Door opens but won't close/latch properly, Clicking sound from nose panel when pressing release, Manual emergency release cable required to open
Fix: Small plastic actuator motor breaks or gear strips. Access requires removing front fascia clips. Actuator replacement takes 1-2 hours. Aftermarket parts available but OEM lasts longer.
Estimated cost: $300-550
Reduction Gear Oil Leak
Occasional · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Oil spots under front of vehicle (reddish fluid), Whining noise from motor area increases, Low fluid level visible on dipstick if checked, Grinding sensation during acceleration if severely low
Fix: Single-speed reduction gear uses special gear oil. Common leak points are output shaft seal and drain plug. Seal replacement requires 3-4 hours labor, drain/refill and reseal. Uses Nissan NS-3 fluid or equivalent—critical to use correct spec.
Estimated cost: $450-850
Owner tips
Check battery health bars (dash display) and LeafSpy data before purchase—anything below 10 bars means significant degradation
Replace 12V battery every 3-4 years preventively—it's the most common failure that strands owners
Avoid DC fast charging in extreme heat when possible—it accelerates battery degradation on these passively-cooled packs
Keep reduction gear oil changed every 60,000 miles even though Nissan says lifetime—cheap insurance for $150
Buy if under 60k miles with 11-12 battery bars and you have realistic range expectations—just budget $500/year for eventual battery replacement or trade before 80k miles.

Nissan North America, Inc. (Nissan) is recalling certain 2013-2017 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 May 26, 2023. Owners may contact Nissan's customer service at 1-800-867-7669. Nissan's number for this recall is R23A1.
