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
Owners report severe, recurring electrical problems on 2015 Sentras that dealerships struggle to diagnose or repair. The most persistent complaint is the P0101 (mass airflow sensor) code, which causes check engine lights and engine stalling at highway speeds. Multiple owners have replaced the MAF sensor five times or as frequently as every three months, cleaned throttle bodies per Nissan TSBs, and still see the fault return within two to three weeks. One owner's engine stalled at 50 mph, nearly causing an accident.
Airbag and seatbelt warning lights malfunction frequently: passenger occupant classification lights stay illuminated even with unoccupied seats (contrary to owner's manual specs), driver airbag lights remain on with non-functional airbags, and seatbelt warning lights flicker or stay lit despite proper engagement. One vehicle suffered catastrophic engine fire from an electrical fault. Keyless ignition failures have left engines running for hours in closed garages, exposing occupants to carbon monoxide. A dealership car wash soaked a Sentra's interior, triggering multiple electrical failures; the dealer attempted cover-up and refused full restitution. Door locks, transmission shifting, radio displays, horns, and alarm systems all fail in various combinations. Dealers consistently either deny problems exist, claim faults are normal operation, or cannot identify root causes.

Failure modes owners describe
Mass Airflow (MAF) Sensor Malfunction
Check engine light triggered by P0101 code (MAF sensor fault). Multiple owners report replacing the MAF sensor repeatedly (5 times in one case, every 3 months in another) with factory parts, cleaning throttle body, and following TSBs, but the fault returns within weeks. Engine stalls under light acceleration and at highway speeds, creating safety hazards.
When: Recurring within 2-3 weeks after repair; one owner reports every 3 months
Symptoms owners cite: Check engine light illuminates; Engine stalls while driving at highway speeds (50+ mph); Poor acceleration from complete stop; Rough idle and RPM fluctuations; Car loses power mid-drive
Codes mentioned: P0101, P0846, P0965, P0747
Repairs/costs cited: MAF sensor replaced multiple times (5 replacements reported); throttle body cleaned; Nissan TSB work performed; repairs temporary, fault returns within weeks
Recalls/TSBs owners mention: Nissan TSBs issued but did not resolve underlying issue; dealer unable to determine root cause
Keyless Ignition System Failure
Engine fails to auto-shut-off when owner exits vehicle. Two separate incidents: one owner found car running in closed garage for 7 hours, exposing occupants to carbon monoxide; another woke to find engine running overnight after parking. Keyless fob proximity detection appears to malfunction.
When: Incident 1: after 7 hours in garage; Incident 2: overnight (discovered next morning at approximately 22,000 miles)
Symptoms owners cite: Engine remains running after owner exits and locks vehicle; No auto shut-off despite fob distance from vehicle; Carbon monoxide exposure from prolonged idling in closed space
Repairs/costs cited: No repair notes provided; dealers contacted but unable to determine cause
Seatbelt Warning Light Malfunction
Seatbelt warning indicator remains illuminated continuously on dashboard despite proper seatbelt engagement. Indicator fails to extinguish when seatbelt fastened or when vehicle parked. One case involved water damage from dealership car wash; another shows no obvious cause.
When: Continuous after ignition on; one case following water damage
Symptoms owners cite: Seatbelt light stays on constantly; Light flickers on and off intermittently (water-damage case); Removal and reconnection of seatbelt does not clear fault
Repairs/costs cited: Seatbelt replaced; electrical connections checked and appear intact; water-damaged vehicle: seatbelt and front seat bottom cushion replaced by dealership
Recalls/TSBs owners mention: Dealership repair attempts; one case involved cover-up and unresolved dispute
Airbag System Faults
Airbag warning light remains on; occupant classification system (OCS) passenger airbag status light stays illuminated constantly when seat unoccupied, contrary to owner's manual specifications. Driver-side airbag reported non-functional. Multiple owners cite dealer resistance to acknowledging fault.
When: Continuous; one case recurring after previous airbag repair
Symptoms owners cite: Airbag warning light stays on while driving; Passenger airbag status light illuminated even with seat unoccupied; Driver-side airbag does not deploy; Bright yellow light distracting, especially at night
Repairs/costs cited: Airbag system repaired previously in one case; passenger status light remains on despite repair
Recalls/TSBs owners mention: Dealers claim light functioning normally when unoccupied seat light stays on; dispute with owner's manual interpretation
Engine Fire - Electrical Origin
Vehicle caught fire while parked after short drive. Fire department investigation indicated electrical system failure as likely cause. Catastrophic failure with potential for injury or death.
When: 15 minutes after parking vehicle
Symptoms owners cite: Smoke and fire originating from engine compartment; Fire department called to extinguish
Repairs/costs cited: Fire department attended; no repair notes provided
Water Intrusion from Dealership Negligence
Dealership service department ran vehicle through car wash with windows down during oil change, soaking interior. Dealership attempted to conceal damage by drying interior. Water seeped from door handles, cup holders, armrests, dashboard, and seat bottoms. Multiple electrical failures resulted: dim radio screen, flickering seatbelt light, airbag warning light issues.
When: During oil change service
Symptoms owners cite: Water pooling and seeping from door handles, cup holders, armrests; Water pouring from bottom of seats; Radio screen very dim; Seatbelt light flickering on and off; Airbag warning light activation
Repairs/costs cited: Dealership replaced seatbelt and front seat bottom cushion; damage assessment incomplete; owner claims widespread water damage never fully addressed
Recalls/TSBs owners mention: Dealership denied full replacement; offered partial repairs only; owner dispute unresolved
Door Lock Inoperability
Door locks became inoperable on vehicle. Occurred alongside engine running failure. Dealer contacted but unable to determine cause.
When: Approximately 22,000 miles
Symptoms owners cite: Door locks non-functional
Recalls/TSBs owners mention: Dealer unable to determine cause
Throttle Control Light and Rough Running
Throttle control warning light illuminates; vehicle runs rough with RPM fluctuations and loss of speed. Owner indicated recall may apply but dealers claimed no recall exists.
Symptoms owners cite: Throttle control light illuminates; Rough engine idle and operation; RPM spikes and drops; Loss of vehicle speed
Recalls/TSBs owners mention: Dealer claims no recall applies despite owner belief
Transmission Shifting and Jerking Issues
Vehicle jerks during acceleration; transmission fails to shift gears despite engine running. After transmission repair with multiple parts replaced, jerking continues at 50 mph. Secondary electrical issues: horn non-functional, loud noise during tight turns.
When: Recurring after transmission repair
Symptoms owners cite: Car jerks when driven; Transmission won't shift despite engine running; Jerking at 50 mph after repair; Horn inoperative; Alarm system inoperative; Loud noise during tight turns
