What stands out
No new NHTSA electrical complaint has been filed on this vehicle in over 8 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 2012 Murano electrical complaints cluster around three dangerous patterns. First, unwarned engine stalling during normal driving—owners describe the car simply cutting off at highway speeds (70 mph on interstates, 30 mph in town, while turning or climbing hills) with no warning lights, then refusing to restart. One owner had this happen four times; another saw it three times, each time coasting to safety after losing power. Dealers and mechanics cannot replicate or fix it even after overnight diagnostics.
Second, parasitic battery drain. Multiple owners park their cars with nothing left on—not even interior lights working—and the battery is completely dead hours later. Replacement batteries last anywhere from 3 weeks to 1.5 years before the same drain kills them again. Dealerships cannot identify the source.
Third, door lock failures: all four actuators stop working, doors won't lock above 15 mph, and manually locked doors stay locked when you shut off the engine. One owner also reported a stuck rear hatch.
One complaint mentions an Intoxalock interlock device draining battery and killing power. Dashboard noises with GPS screen blackouts appear in two reports. Nissan has not issued recalls and has offered no solutions; owners are paying out of pocket for repeated part replacements with no resolution.

Failure modes owners describe
Stalling while driving with no restart
Engine shuts off completely while in motion without warning lights or indicators. Vehicle loses all electrical power or fails to restart after stalling. Occurs at various speeds and conditions (highway, turns, hills). Poses serious safety risk as steering and braking may still work but vehicle becomes immobile.
When: Various mileages reported: 72k, 125.6k miles. Incidents occur during normal driving.
Symptoms owners cite: Engine cuts off without warning; No dashboard warning lights prior to stall; Vehicle will not restart after stalling; Occurs while turning or going uphill; Loss of electrical power
Repairs/costs cited: Owners report battery replacements, alternator replacements (multiple times), sensor replacements. Dealers unable to diagnose or repair despite keeping vehicle overnight. Local mechanics also unable to replicate or fix issue.
Recalls/TSBs owners mention: Nissan advised owner of no known recalls and directed them to mechanic. No warranty programs or TSBs mentioned.
Parasitic battery drain
Battery drains completely when vehicle is parked with nothing left on. Occurs suddenly and repeatedly. Dealership unable to identify source of drain. One owner notes AC fan was only item running; another reports identical incidents twice.
When: No specific mileage reported. Occurs within hours of parking (e.g., 1 PM to 5 PM same day).
Symptoms owners cite: Battery completely dead when parked; No known electrical accessories left on; Interior lights do not function; Remote door locks inoperative when battery dead; Repeated occurrences with replacement batteries
Repairs/costs cited: Jump-starting vehicle resolves immediate issue. Owners report multiple battery replacements (2-4 new batteries) within short periods. Dealership unable to locate fault source.
Door lock actuator failure
All four door lock actuators fail to function properly. Doors will not lock automatically at highway speeds (safety feature disabled). Manually locked doors will not unlock when engine is shut off, creating potential safety hazard.
When: No specific mileage or timing provided.
Symptoms owners cite: Door locks do not engage above 15 mph; All four door lock actuators non-functional; Manually locked doors remain locked when engine shut off; Cannot unlock doors without power
Rear electrical door malfunction
Rear electrical door (hatch/liftgate) becomes stuck in open position and will not close. Indicates broader electrical system failure.
When: Occurred in October 2017 at 125.6k miles.
Symptoms owners cite: Rear electrical door stuck in open position; Inoperative door control
Repairs/costs cited: Dealer (Cherry Hill Nissan, NJ) performed electrical repair.
Recalls/TSBs owners mention: Manufacturer was notified of failures.
Dashboard noise with GPS/screen blackout
Loud noise originates from underneath dashboard GPS screen area. Screen goes black temporarily then restores. Occurs during normal driving at moderate speeds.
When: At 9k miles (one instance); another instance at around 30 mph during normal operation.
Symptoms owners cite: Loud noise from under dashboard/GPS screen area; Screen goes black; Screen restores after 45 seconds
Repairs/costs cited: Dealer unable to determine cause and identify what parts need replacement at 9k miles. Vehicle not repaired.
Aftermarket device interaction (Intoxalock)
Installation of Intoxalock interlock device causes complete loss of vehicle power while driving. Device continuously drains battery. No warning signs before power loss occurs.
When: No specific mileage or timing provided.
Symptoms owners cite: Complete loss of vehicle power while driving; Continuous battery drain; No warning indicators; Safety risk to driver and other motorists
Repairs/costs cited: Device has had diagnostics performed but continues to cause safety issues.
