What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering electrical on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

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
full bulletin at NHTSA ↗SILICONE-BASED LUBRICANT OR GREASE CAN DAMAGE ELECTRICAL COMPONENTS SERVICE INFORMATION Do not apply Silicone-based lubricants or grease to, or around, any interior electrical components. To avoid the risk of death or severe personal injury, do not directly spray Silicone-based lubricant or grease, or inadvertently overspray Silicone-based lubricant or grease onto any interior electrical components. These types of lubricants can be detrimental to the proper operation of electrical components.

The failure pattern owners describe
Owners of 2016 Nissan Leafs report electrical and battery failures across multiple systems. One owner's 12-volt battery cell failed, causing confusion between regenerative and hydraulic braking that required very hard pedal pressure to engage the brakes—dangerous during heavy foot traffic at a senior center. Another owner lost 38% of the vehicle's range in one year (from 110 miles to 68 miles), with dealerships insisting the degradation was normal despite the car becoming unusable for daily commutes.
More critically, multiple owners report complete power loss at highway speeds—the vehicle shifting into neutral involuntarily and refusing to shift back into drive. One case involved losing all power at 75% charge going uphill; another at 60–70 mph on a freeway. Jump starts temporarily restored function, but dealers confirmed battery malfunction and in one case advised the owner not to drive the vehicle pending battery replacement, with wait times stretching to one year.
A capacitor and battery cells replaced by a dealer did not resolve a false low-battery warning that triggered unwanted deceleration. One owner's vehicle caught fire while parked at home at 22,000 miles; the manufacturer claimed defective battery installation and denied responsibility. A traction motor inverter failure left another owner unable to charge or start the car.

Failure modes owners describe
12-Volt Battery Failure — Brake/Regenerative Braking Confusion
A bad 12-volt battery cell causes the vehicle's electrical system to misinterpret signals between the regenerative and hydraulic braking systems, resulting in brake engagement failure that requires hard pedal pressure to engage. The narrative notes dashboard flickering at startup and lights-on buzzer sounding at shutdown despite lights being off.
When: Within first few months of ownership; symptoms noted prior to brake failure event
Symptoms owners cite: Brake pedal requires very hard pressure to engage brakes; Dashboard display flashes with missing numbers then normalizes; Lights-on buzzer sounds at shutdown even when lights are off; 12-volt battery voltage low (~10 volts vs. normal 12+ volts)
Repairs/costs cited: Owner replaced 12-volt battery with NAPA aftermarket unit; NAPA confirmed bad cell in original battery. No dealer diagnosis or TSB mentioned.
Rapid Traction Battery Capacity Loss — Loss of Range Bars
The traction battery degrades significantly faster than normal in early ownership. An owner reported 38% range loss in one year (110 miles at lease start in October 2016 to 68 miles by October 2023), with documented loss of two capacity 'bars' and battery reaching only 8 bars. Dealerships repeatedly tell owners this is normal despite severe functional impact on daily commuting.
When: Starting within first month of ownership; progresses over 12+ months. One documented case: October 2016 baseline; by August 2017 degradation noted; 2 bars lost by October 2023.
Symptoms owners cite: Dramatic range reduction (reported examples: 110 miles to 68 miles in ~1 year; another: 64 miles at 10k miles when new); Loss of capacity 'bars' displayed on dashboard; Battery depletes rapidly once charge reaches 20%; Loss of power when driving uphill
Repairs/costs cited: No repairs documented in narratives. Dealers claim this is normal and refuse to acknowledge as defect. One owner reported battery on back-order for up to one year under warranty.
Recalls/TSBs owners mention: Nissan claims battery degradation is normal and expected; warranty claims placed but with long lead times (up to one year for replacement)
Traction Battery Failure — Loss of Power and Neutral Shift During Highway Driving
The vehicle loses all electrical power while driving at highway speeds, shifts into neutral, and will not shift back into drive. A jump start temporarily restores function. One owner reported error code P3398 with battery malfunction. Another experienced complete shutdown at 60 mph uphill with no warning lights. A third reported vehicle stuck in neutral after shutdown with battery disconnection showing low battery voltage codes.
When: Varied timing: one case at 47 miles remaining charge; another at 75% charge; another with prior warning of power loss on inclines starting months before failure
Symptoms owners cite: Complete loss of power while driving at highway speed (60–70 mph); Vehicle shifts into neutral involuntarily and will not shift back to drive; Vehicle stuck in neutral after shutdown; Power loss on inclines (observed for months prior in one case before full failure); No warning lights displayed prior to failure in most cases
Codes mentioned: P3398 (battery malfunction), P0AA0 (low battery voltage), P3180 (low battery voltage), P3182 (low battery voltage), P08AF (low battery voltage)
Repairs/costs cited: One owner: dealer found error code P3398 and stated battery is unsafe; battery replacement delayed many months. Another: dealer confirmed battery compromise and advised not to drive; vehicle towed. Third: jump start restored function temporarily.
Recalls/TSBs owners mention: Warranty covers battery replacement but with months-long back-order delays (up to one year reported). One dealer refused further clarification. No manufacturer field inspection documented.
False Low Battery Mode Warning During Full Charge
A 'Low Battery Mode' warning message displays and triggers automatic deceleration ('turtle mode') even though the battery is fully charged. The failure recurred after dealer replaced a capacitor and three battery cells, indicating an unresolved underlying issue.
When: At approximately 54,000 miles
Symptoms owners cite: 'Low Battery Mode' warning displayed while battery is fully charged; Vehicle decelerates inadvertently (enters 'turtle mode'); Failure recurs after repair attempt
Repairs/costs cited: Dealer replaced capacitor and three cells in the traction battery; failure recurred despite repair.
Recalls/TSBs owners mention: Manufacturer advised owner to return to dealer for additional diagnostic testing; vehicle had pending appointment.
Traction Motor Inverter Failure
The traction motor inverter fails, rendering the vehicle unable to charge or start. No further details provided in the narrative.
Symptoms owners cite: Vehicle will not charge; Vehicle will not start
Vehicle Fire — Battery-Related Spontaneous Combustion
The vehicle caught fire while parked at the owner's residence at approximately 22,000 miles. The fire department extinguished the fire; no injuries occurred but the vehicle was totaled. Manufacturer opened an investigation and claimed the failure was due to defective installation of the original battery, but denied responsibility.
When: At approximately 22,000 miles; occurred while vehicle was parked at residence
Symptoms owners cite: Vehicle engulfed in flames
Repairs/costs cited: Vehicle towed to salvage yard and deemed a total loss.
Recalls/TSBs owners mention: Manufacturer contacted, investigation opened. Manufacturer claimed failure due to defective installation of original battery and denied responsibility.

We were driving the car on a highway (the 405 in Los Angeles) in the midafternoon on December 21. We were going uphill and in the flow of traffic. I'd say the speed was about 60-65. The car was functioning well. Then, the driver accelerated to pass a car and suddenly the car lost all power and went into neutral. Fortunately, we made our way to the freeway shoulder without an accident. But,…
December 07, 2016 I bought Nissan leaf 2016 in june 30, 2016. On november 29, 2016, it just stopped and not going in reverse or forward, just stay on neutral and park. It has two recalls issued by transport canada (# 2016179 an # 2016302). Nissan canada never send my any notification about recalls. On november 29, 2016 it was towed to the dealership, 401/dixie mississauga, on canada.since then…
While driving at speeds of 70 MPH, my car turns off in the middle of the highway! I have a video of this ordeal that I'd be happy to send over.
On Friday, November 1, at about 3 pm, the brakes failed pulling away from the curb in a forward direction after loading equipment into the vehicle. Really stomping the brakes as though they had a fluid problem did get them to engage. I think the problem occured again backing out of my driveway prior to Monday the 4th when I fixed the problem. Again, really slamming the brake peddle got the brake…
My battery lost 2 of my 12 range bars and Nissan does not see any of this as an issue, october 06, 2016 - 110 mile range march 04, 2017 - august 28, 2017 - 76 mile range ' 1 bar loss october 23, 2017 - 65 - 72 mile range ' 2 bar loss I can no longer make my commute after 1 year of usage.…
Traction motor inverter failure on 2016 Nissan leaf. When this incident occurred, I was not able to charge or start the car.
I do not have much range. At 100% charged I'm getting a range of 64 miles. Considering the car only has 10k miles on it, that's terrible range. My car was sitting still, in park and turned on when I took this image.
