What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 5 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
The 2015 Pathfinder's electrical system shows a pattern of interconnected failures centered on the brake interlock and relay network. Most common is intermittent loss of acceleration after braking, often accompanied by brake lights staying illuminated while the vehicle is parked and off. Owners report pressing the accelerator fully with no response, sometimes requiring a vehicle restart or double-tapping the brake to restore power. One owner had to perform a $500 workaround involving two wiring harnesses and a switch to bypass the brake relay—a fix Nissan's own dealership called a "factory defect." The brake system issue appears to trigger cascading problems: traction control lights illuminate, skid warnings trigger for no reason, and the vehicle can be shifted into drive without pressing the brake pedal.
Secondary electrical failures include battery corrosion and drain issues, with some vehicles requiring multiple battery replacements despite low mileage. One case identified a tow bar accessory pulling 4 amps continuously. A faulty crankshaft sensor caused stalling and acceleration loss on highways. The power liftgate fails unpredictably, closing on occupants when cargo is being loaded; water intrusion from weathered trim burns out relays. Cooling fan assemblies produce loud grinding noise. Owners note that recall campaigns for 2013–2014 models with identical faults do not cover the 2015 version, despite ongoing issues being documented across multiple forums.

Failure modes owners describe
Loss of acceleration with brake system issues
Vehicle loses acceleration response from complete stop or during traffic, often accompanied by brake light illumination problems and sometimes traction control light activation. Owners report pressing the gas pedal fully with no response, sometimes requiring a restart or double-tapping the brake to restore function. Dealership diagnosis points to faulty brake/shift interlock relays or brake switch issues.
When: Intermittent, occurring at traffic stops, stop signs, red lights, highway merges, and immediately after braking
Symptoms owners cite: No acceleration or limited acceleration (under 10 mph) from complete stop; Requires restart or double-tap brake to restore power; Brake lights remain illuminated while driving or parked with engine off; Traction control light illuminates and stays on until restart; Vehicle can be put in drive without depressing brake pedal; Skid/traction control warning light comes on for no reason
Repairs/costs cited: Dealership replaced faulty relays (brake relay switch). One owner cited a workaround involving two wiring harnesses and a switch to bypass brake switch relay and reroute to body control module, quoted at $500 plus diagnostics. Another owner mentioned $1200 relay replacement in driver seat.
Recalls/TSBs owners mention: Nissan acknowledged factory defect (case #30341997) but charged customer for parts and labor on workaround. Owners note recalls exist for 2013–2014 Pathfinder models with same fault but 2015 model not included in active recalls.
Battery corrosion and drain issues
Multiple reports of heavily corroded battery terminals causing starting and stalling problems. Vehicle drains battery power even with new battery installed. One case traced excessive drain to a tow bar accessory pulling 4 amps continuously.
When: Occurring on relatively low-mileage vehicles (75k miles), with battery replacement required multiple times
Symptoms owners cite: Battery heavily corroded at terminals; Vehicle stalls when shifting from park to reverse or drive; Battery drainage causing starting failures; Multiple battery replacements on single vehicle
Repairs/costs cited: Battery replacement (third replacement in one case). Tow bar accessory identified as drain source in one complaint; owner advised to return vehicle to point of purchase for tow bar repair. Brake/starter switch adjustment mentioned in another case.
Faulty alternator causing power loss
Alternator failure results in loss of acceleration and inability to maintain power. Dealer diagnosis confirmed faulty alternator requiring replacement.
When: At 120,000 miles
Symptoms owners cite: Sudden loss of acceleration while driving; Vehicle operates normally in reverse only; Power loss recurs after temporary recovery
Repairs/costs cited: Alternator replaced by dealer.
Recalls/TSBs owners mention: Nissan notified and provided case number 37487331.
Crankshaft sensor failure
Faulty crankshaft sensor causes stalling and loss of acceleration on highway and local roads, triggering check engine light.
When: <UNKNOWN>
Symptoms owners cite: Sudden stalling on highway and local roads; No acceleration response, vehicle stuck at same speed; Check engine light illuminated; Considerable slowing of traffic flow
Repairs/costs cited: Crankshaft sensor replacement.
Power liftgate malfunction
Rear power liftgate closes unexpectedly after reaching full open position, creating head and neck injury hazard when loading cargo. Issue appears random and has been present since vehicle purchase. Chrome trim weathering allows water intrusion onto relay switch, causing burnt relays or blown fuses and preventing operation.
When: Random occurrence; documented since vehicle purchase in 2015, first incident May 2020
Symptoms owners cite: Liftgate closes on its own after reaching full open position; Creates hazard for occupants reaching into cargo area; Random failure with no apparent trigger; Water ingress from weathered chrome trim causing electrical relay burnout
Repairs/costs cited: Dealer unable to repair because problem is random. Water damage to relay switch from chrome panel deterioration requires relay or fuse replacement.
Recalls/TSBs owners mention: Recall exists for 2013–2014 Pathfinder but does not cover 2015 model. Owner reports issue documented in forums since 2014.
Engine cooling fan assembly noise
Loud grinding or vibration noise from cooling fan assembly when AC or heat activated, originating from driver-side fan. Noise persists whether vehicle is moving or stationary. Owner research suggests wheel bearing failure inside fan assembly.
When: <UNKNOWN>
Symptoms owners cite: Loud grinding or vibration noise from cooling fan; Noise occurs when AC or heat turned on; Noise present whether vehicle moving or stationary; Noise ceases when AC/heat turned off
Repairs/costs cited: No repairs cited by owners.
Recalls/TSBs owners mention: Separate recall existed for 2013–2014 Pathfinder but does not cover 2015 model.
Intermittent airbag warning indicator
Airbag warning light illuminates intermittently when front passenger is seated, recurring despite dealer reset of airbag sensor.
When: At low mileage (5,000 miles)
Symptoms owners cite: Airbag warning indicator illuminates intermittently; Warning recurs on several occasions
Repairs/costs cited: Dealer reset airbag sensor, but failure recurred.
Recalls/TSBs owners mention: Vehicle VIN not included in NHTSA campaign 14V138000 (airbags, electrical system). Manufacturer not notified by owner.
Keyless start button accidental activation
Start button located in unsafe position where driver's knee makes contact while driving, causing unintended engine shutdown while vehicle in motion.
When: <UNKNOWN>
Symptoms owners cite: Knee contacts start button while driving; Vehicle stalls unexpectedly
Stalling with unresponsive brakes
Vehicle stalls at highway speeds with automatic brake engagement and automatic system behavior. Owners report brakes come on automatically and suspect sensor malfunction, but problem persists.
When: <UNKNOWN>
Symptoms owners cite: Vehicle stalls on highway at speed (e.g., 75 mph); Automatic brake engagement; Repeated stalling without clear pattern
Repairs/costs cited: No successful repairs; dealer could not consistently reproduce or diagnose.
Recalls/TSBs owners mention: Nissan notified of one incident but no repair attempt made.
Automatic locking/unlocking and dashboard warning signals
Vehicle exhibits unexpected automatic door unlocking and dome light activation triggered by false back gate open warning. Multiple self-activations suggest electrical control module or sensor issue.
When: <UNKNOWN>
Symptoms owners cite: Back gate open warning displays on dashboard; Dome lights turn on automatically; Doors unlock by themselves; Multiple recurrences

What owners are reporting 2 most recent
The car suddenly started stalling on the highway and would not accelerate and stuck at the same speed. The check engine light came on. This happened a few times where the car would stall and the acceleration would not work on local roads as well as the interstate thus considerably slowing the speed of the traffic upon getting it inspected at the dealership, they found the crankshaft sensor was…
The vehicle makes a lot of noise when the ac or heat is turned on. Seems to originate from the cooling fans. When the ac or heat is turned off the sound goes off too. It's very loud seems like the fans are going off. Makes the noise whether moving or still as long as the ac or heat is on.
