The 2015 Nissan Leaf is mechanically simple with no engine or transmission in the traditional sense, but it's plagued by rapid battery degradation in hot climates and some onboard charger failures. Most documented 'transmission/engine' repairs in databases are data errors—this is a pure EV.
Rapid Battery Capacity Loss (Especially in Hot Climates)
Common · high severity
Typical onset: 40,000-80,000 mi or 5-7 years
Symptoms: Range drops from original 84 miles to 50-60 miles on full charge, Loss of one or more capacity bars on dashboard gauge, Accelerated degradation in Arizona, Texas, Southern California, Battery State of Health (SOH) below 70% on diagnostic scan
Fix: Battery replacement requires 6-8 hours labor for pack removal and reinstallation. Nissan charges $5,500+ for refurbished 24 kWh pack (when available), aftermarket remanufactured packs run $3,500-4,500 plus core. No passive cooling system means degradation is permanent.
Estimated cost: $4,500-8,500
Onboard Charger Failure
Occasional · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Vehicle won't charge on Level 1 or Level 2, but DC fast charging still works, Red warning light on dash with 'EV System' message, No activity/clicking when plugged into 120V or 240V charger, Diagnostic code P318F or P318C (charger control circuit)
Fix: Onboard charger (OBC) located under hood requires 2-3 hours removal and replacement. Nissan part runs $1,200-1,800, remanufactured aftermarket units $600-900. Some failures traced to water intrusion through poorly-sealed connector.
Symptoms: Vehicle completely dead, won't power on or unlock, Dashboard warning: 'Shift to P and restart', Clicking from relays but no Ready light, Traction battery full but car won't initialize
Fix: Standard 12V battery replacement, but Leaf drains it faster than gas cars due to always-on computers. 0.5-1 hour labor. Battery is located under hood in standard location. Use Group 35 or 51R battery, AGM preferred for longevity.
Estimated cost: $200-350
Inverter Coolant Pump Failure
Occasional · medium severity
Typical onset: 80,000-120,000 mi
Symptoms: Reduced power warning light (turtle icon), Motor overheating on highway drives or in traffic, Whining or grinding noise from under hood near motor compartment, Diagnostic code P1A15 (inverter cooling system)
Fix: Electric coolant pump replacement requires 2-3 hours labor. Pump is part of motor/inverter cooling loop. Nissan OEM pump $400-600, aftermarket $250-400. Must bleed air from system after replacement to prevent motor overheating.
Symptoms: Passenger airbag light stays on or off incorrectly, Adult passenger triggers 'airbag off' light, Airbag warning light illuminated on dash
Fix: NHTSA recall 17V-244 addresses faulty seat sensor mat in passenger seat. Dealer replacement takes 1-2 hours, covered under recall. If out of recall window, passenger seat sensor mat replacement $300-600 parts plus 1.5 hours labor.
Estimated cost: $0 if recall applies, $450-800 otherwise
Charge Port Door Latch Failure
Occasional · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Charge port door won't open when button pushed, Door pops open while driving, Manual release cable required every time, Clicking sound but door doesn't release
Fix: Plastic latch mechanism breaks or actuator motor fails. Replacement takes 1-1.5 hours, requires removing inner fender liner. OEM door assembly $200-300, aftermarket $100-150. Can temporarily use manual release cable in trunk.
Estimated cost: $250-450
Reduction Gear (Gearbox) Oil Leak
Rare · medium severity
Typical onset: 100,000+ mi
Symptoms: Gear oil puddle under front of vehicle, Whining noise from motor/transaxle area, Low fluid triggers 'EV system' warning, Oil visible on motor housing or belly pan
Fix: Output shaft seal or case gasket failure. Requires 3-5 hours labor to drop reduction gear assembly, replace seal/gasket, refill with NS-3 gear oil. Seal kit $50-100, fluid $30. Check for metal contamination in old fluid indicating gear wear.
Estimated cost: $400-800
Owner tips
Check battery State of Health (SOH) with LeafSpy app before buying—anything under 75% SOH means very limited range
Avoid 2015 Leafs from hot climates (AZ, NV, TX, SoCal) unless battery has been replaced—degradation is permanent
Budget $200 for 12V battery every 4-5 years—Leaf kills them faster than gas cars
DC fast charging works independently of onboard charger, so test both Level 2 and CHAdeMO charging during pre-purchase inspection
No transmission fluid, engine oil, or spark plugs—maintenance is mostly tires, brakes (which last forever due to regen), and cabin air filter
Buy only if you need <60 miles daily range, can charge at home, and find one with documented SOH above 80%—otherwise battery replacement cost exceeds vehicle value.

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.
AIR BAGS · 17V253000
2017-04-13
Nissan North America, Inc. (Nissan) is recalling certain 2015-2017 LEAF and 2014, 2016 and 2017 Sentra vehicles. Due to a manufacturing error within the air bag inflators, the passenger frontal air bag may not properly deploy in the event of a crash.
Consequence: In the event of a crash, if the front passenger air bag doesn't deploy properly, it can increase the risk of injury to passengers.
Remedy: Nissan will notify owners, and dealers will replace the front passenger air bag inflator, free of charge. The recall began June 7, 2017. Owners may contact Nissan customer service at 1-800-647-7261.
AIR BAGS:SENSOR:OCCUPANT CLASSIFICATION · 16V244000
2016-04-26 · EA15004
Nissan North America, Inc. (Nissan) is recalling certain model year 2016-2017 Nissan Maxima, 2013-2016 Nissan Altima, NV200, LEAF, Sentra, and Pathfinder, 2014-2016 Nissan NV200 Taxi, Infiniti QX60, QX60 Hybrid, and Q50 Hybrid, 2014-2017 Nissan Rogue and Infiniti Q50, 2015-2016 Nissan Murano, Murano Hybrid, and Chevrolet City Express, 2014-2015 Nissan Pathfinder Hybrid, and 2013 Infiniti JX35 vehicles. In these vehicles, the front seat passenger Occupant Classification System (OCS) may incorrectly classify an adult passenger as a child or classify the seat as empty despite it being occupied. As a result, the passenger frontal air bag may be turned off and not deploy in the event of a crash.
Consequence: If the passenger frontal air bag does not deploy as intended in the event of a crash, the passenger is at an increased risk of injury.
Remedy: Nissan will notify their owners. Chevrolet City Express owners will be notified by General Motors. Dealers will reprogram the Air Bag Control Unit (ACU) and OCS Electronic Control Unit (ECU) in Altima, Maxima, Murano, Rogue, and Sentra vehicles, and replace the OCS ECU in LEAF, NV200, NV200 Taxi, Pathfinder, Infiniti Q50, JX35, and QX60 and Chevrolet City Express vehicles, free of charge. Interim notices were sent to owners on May 31, 2016. Owners will receive a second notice when remedy parts become available. Owners may contact Nissan customer service at 1-800-867-7669, Infiniti customer service at 1-888-833-3216 or Chevrolet customer service at 1-800-222-1020.
SERVICE BRAKES · 16V119000
2016-02-29
Nissan North America, Inc. (Nissan) is recalling certain model year 2013-2015 LEAF vehicles manufactured November 19, 2012, to July 31, 2015. During very cold temperatures, the relay inside the electronic brake booster may freeze, requiring the driver to exert more effort to slow the vehicle down.
Consequence: If the brake relay fails, longer distances or additional brake effort would be required to stop the vehicle, increasing the risk of a crash.
Remedy: Nissan will notify owners, and dealers will reprogram the Intelligent Brake Control Unit software, free of charge. The recall began on March 28, 2016. Owners may contact Nissan customer service at 1-800-647-7261.
