full bulletin at NHTSA ↗12 VOLT BATTERY TESTING FOR IN-SERVICE VEHICLES SERVICE INFORMATION The following Service Information lists NNA procedural recommendations for establishing good connections while performing 12V battery testing. These recommendations are expected to promote uniformity during the connection process, therefore reducing the number of incorrect âTest with DCAâ and âReplaceâ results. HINT: If 12 volt batteries are allowed to discharge for a prolonged period of time, battery life may be drastically reduced. This condition may lead to premature battery replacement and customer dissatisfaction. IMPORTANT: ï· CPX-900 is now an accepted testing tool to use along with or in place of the DSS-500

The failure pattern owners describe
Owners document a cascade of electrical failures in the 2013 Leaf. The 12V battery system is the worst offender—it drains completely in a week without warning, leaving owners stuck with dead-locked doors and dead car. When the battery goes, so do the brakes; one owner needed 10 feet of brake pedal force just to stop from 2 mph. The root cause is a defective DC-DC converter that's poorly programmed; owners report jumping the car fixes it temporarily, but activation of wipers briefly restores charging voltage before it fails again. Nissan has not made reprogramming available.
Charging infrastructure is equally unreliable. Multiple owners report charging randomly cuts off mid-session, and charging port connections overheat badly—two separate incidents involved melted plastic and smoke during normal charging, creating fire hazards. One owner's charging cable was damaged by a rodent, and Nissan's safety system ironically sent 220 volts through exposed wires, creating electrocution risk.
Occupant detection for airbags malfunctions, throwing continuous false warnings and potentially disabling airbag deployment. One owner paid $652.56 out-of-pocket after dealer resets worked only two months. Warranty claims are routinely denied on these safety systems. Vehicle start failures, key fob non-recognition, and unexplained power loss round out the picture—problems dealers cannot diagnose or repeatedly refuse to service.

Failure modes owners describe
Onboard Charger Failure / Charging Cable Damage
Onboard charger system fails after exposure to damaged charging cables or electrical faults. One owner reported an external hazard (rodent-chewed insulation on J1772 cable) caused the safety system to send 220V through damaged wires, resulting in sparks and electrocution risk. The charger became inoperative; repair estimate $7,000. Another owner experienced vehicle unable to complete charging, randomly shutting off at different stations; dealer blamed home station but problem persisted at dealer's charging station.
When: During or shortly after charging sessions; one case after days of non-use followed by charger connection
Symptoms owners cite: Charging stops mid-cycle or randomly shuts off; Unable to fully charge vehicle; Sparks and electrical arcing at J1772 plug connection; Smoke and burning smell from charging port; Melted plastic at charging port receptacle; Charging port terminals damaged
Repairs/costs cited: Replacement of onboard charger system estimated $7,000 parts and labor. One case involved damaged J1772 connector pins and car receptacle terminals requiring replacement.
Recalls/TSBs owners mention: Nissan EV warranty covers onboard charger and onboard charger connector. In one case, warranty was denied; Nissan blamed the home charging station rather than vehicle defect.
12V Battery / DC-DC Converter Charging Defect
12V battery drains excessively or fails to charge properly due to defective DC-DC converter programming. Multiple owners report sudden loss of 12V power while driving, requiring forced shutdown of accessories to restore basic function. One owner confirmed activation of wipers temporarily restores charging voltage, proving a programming issue rather than component damage. Replacement of 12V battery does not resolve the underlying problem.
When: Intermittently during operation; one documented case 11/30/23; happens repeatedly for affected owners; can occur after vehicle sits unused for a few days
Symptoms owners cite: 12V battery goes completely dead (once a week in one case); Sudden loss of electrical power while driving on freeway; Brake system loss of power or severely reduced braking; Loss of safety-critical functions (defrost blower, accessories); Unable to open doors with remote when 12V is dead; Repeated need to jump-start vehicle; Dashboard warning lights illumination
Codes mentioned: C118A, C1A61
Repairs/costs cited: One owner paid $2,817 for replacement of electrically driven integral brake unit plus 12V battery after dealer diagnosed suspected surge damage. However, this repair does not address the root cause (DC-DC converter programming). Reprogramming of DC-DC converter recommended but not offered by Nissan.
Recalls/TSBs owners mention: Nissan warranty did not cover the brake unit failure in one case despite it being safety-critical. Nissan does not offer DC-DC converter reprogramming.
Occupant Detection System (OCS) / Seat Belt Sensor Malfunction
False or incorrect passenger seat occupancy detection causes continuous airbag warning lights and potential failure to deploy airbags in a crash. Seat belt buckle warning lights illuminate when seat is unoccupied. Occupant Detection System sensor or control module is defective, triggering airbag non-deployment warnings.
When: Continuous when vehicle is on, regardless of occupancy; one case recurred after two dealer resets over 2 months
Symptoms owners cite: Seat belt not buckled warning when no one in seat; Passenger airbag light on continuously; Airbag system light blinking continuously; Airbag may not deploy in accident (safety risk)
Repairs/costs cited: One owner paid $652.56 for OCS sensor and control module replacement after three dealer visits. Dealer resets provided only temporary 2-month fixes before issue recurred. Second case suggests passenger seat replacement may be needed at approximately $2,000.
Recalls/TSBs owners mention: Nissan did not cover under original warranty despite safety classification. Nissan was reluctant to pay for repair after warranty expiration per dealership.
Brake System Power Loss / Brake Assist Failure
Electrically driven integral brake unit loses power or function, resulting in severely reduced braking effectiveness. Issues occur after 12V battery discharge and reconnection, or during low 12V power events. Brake pedal requires excessive pressure to engage brakes or brakes fail to engage until pedal pressed nearly all the way down.
When: After 12V battery discharge/reconnection; during low 12V battery events; one case at 2 mph in reverse
Symptoms owners cite: Brakes require much more force than normal to engage; Brake pedal pressed nearly all the way down before engagement; Severe loss of brake pressure; 10 feet needed to stop from 2 mph in reverse; Strange noises from front of car when braking; All warning lights illuminated (yellow, red, brake, ABS, VDC)
Codes mentioned: C118A, C1A61
Repairs/costs cited: Dealer estimated $2,817 for electrically driven integral brake unit replacement plus 12V battery. Removing VDC fuse temporarily stopped sounds but brakes still required more force.
Recalls/TSBs owners mention: Not covered under original warranty despite safety-critical nature. Dealer indicated brake unit internal short due to suspected surge.
Vehicle Power Loss / EV Systems Warning
Vehicle fails to start or loses power unexpectedly with EV systems warning icons displayed on dashboard. Multiple owners report inability to start with all warning lights illuminated or inability to diagnose root cause.
When: While parked; one case after vehicle parked in recreation area
Symptoms owners cite: Car will not start; EV systems warning icons on dashboard; All dashboard lights illuminate; Vehicle becomes immobilized
Repairs/costs cited: One owner towed vehicle to dealership; dealer was unable to diagnose problem and waited for Leaf specialist. Described as non-reproducible.
Recalls/TSBs owners mention: Nissan service centers unable or unwilling to troubleshoot; one dealership repeatedly blamed specialist availability.
Key Fob Recognition / Electrical System Malfunction
Vehicle fails to recognize key fob and becomes inoperable. Associated with broader electrical system malfunctions including window and door lock failures.
When: Intermittent; one case while owner attempted to start vehicle
Symptoms owners cite: Car will not start; Dashboard message indicates car not recognizing key; Only one of four windows would roll down; Doors temporarily locked and refused to unlock
Battery Range / State of Charge Display Inaccuracy
Battery capacity and range display do not accurately reflect actual usable charge. Vehicle shows 9 bars but loses 25% range overnight. Significant range drop while driving does not match display readings.
When: Overnight between charging sessions; while driving
Symptoms owners cite: Range drops from 55 miles to 39 miles overnight; Battery shows 9 bars but range inconsistent with display; Significant range loss while actively driving; Actual battery capacity degraded
Repairs/costs cited: Battery rack under recall for faulty ground, but Nissan claims issue would not affect battery pack or state of charge display.
Recalls/TSBs owners mention: Recall exists for battery rack ground fault but Nissan states it does not affect range display accuracy.
Charging Port Connection Overheating / Arcing
Charging port connection overheats and creates fire hazard with melted plastic and smoke during extended charging sessions. Two separate incidents report melted plastic and damaged terminals at J1772 plug connection and car receptacle.
When: During active charging at 220V home/public stations; after over one hour of charging in one case
Symptoms owners cite: Strong burning smell from charging port area; Smoke coming from connection; Melted plastic at plug and receptacle; Damaged terminals on both plug and car receptacle; Connection becomes hot enough to create fire hazard
Repairs/costs cited: Damaged J1772 connector and car charging port receptacle terminals. Repair costs not specified by owners.
Recalls/TSBs owners mention: Nissan denied warranty coverage in one case (5 months old, under 10,000 miles), blaming the home charging station. In second case, fire hazard occurred at public charging station.
Lithium-Ion Battery Bonding Plate Manufacturing Defect
Internal battery bonding plates fail to meet Nissan internal standards affecting 2011-2019 Leaf models. This is part of a voluntary recall but creates logistical hardship for owners with degraded batteries unable to drive to service facilities.
When: Identified through recall; timing of actual failure not specified
Symptoms owners cite: Battery bonding plates may fail internally; Battery degradation
Repairs/costs cited: Recall-related repair requires tow both ways if recommended servicing facility does not service EVs and next facility is beyond degraded battery range.
Recalls/TSBs owners mention: Voluntary recall issued for bonding plate defect. Nissan refuses to provide towing assistance despite safety nature of recall.
Dashboard Warning Light Manipulation via Remote Control
Safety indicator lights can be turned on and off via remote control access, potentially by unauthorized users. This creates confusion about actual vehicle problems and could prompt unnecessary roadside vehicle inspections in unsafe locations.
When: Can occur while vehicle is in motion
Symptoms owners cite: Indicator lights manipulated on/off via remote control; False warning indicators (e.g., tire pressure warnings when no actual problem); Potential to mislead driver about vehicle condition

What owners are reporting 2 most recent
The car suddenly lost power during freeway driving. The brake system appeared compromised. Turning off 12v accessories - which includes safety critical functions such as the defrost blower - was necessary to restore functionality. This is caused by a defective DC-DC converter that fails to properly charge the 12V battery, risking and repeatedly causing sudden loss power, loss of braking, and…
The Nissan Leaf has a 6,600 watt charger that is attached to the top of the 26,000 watt electrical motor. A 30 Amp Nissan charging cord connects the 220 volt electrical outlet (dryer) to the Leaf via a Society of Automotive Engineers (SAE) J1772 Plug. Unknown to me a desert rat had chewed the insulation down to the wires of the charging cord, leaving the wires bare. The desert rat was not…
