The 2014 Nissan NV with the 5.6L V8 is a workhorse commercial van that's mostly reliable when maintained, but suffers from two critical weakness areas: transmission cooler failures that can destroy the transmission, and a catastrophic engine consumption/failure issue tied to a known piston ring defect that affects pre-2015 production runs.
Transmission Oil Cooler Failure Leading to Transmission Damage
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Transmission fluid mixing with coolant (strawberry milkshake appearance in coolant reservoir), Transmission slipping or delayed engagement, Overheating transmission temps, Metal shavings in transmission pan
Fix: The internal transmission cooler in the radiator fails, allowing coolant and ATF to cross-contaminate. This requires radiator replacement (1.5 hrs), complete transmission flush with new fluid and filter (2 hrs), or if caught late, full transmission rebuild or replacement (12-16 hrs). Many techs recommend external cooler bypass as preventive measure.
Estimated cost: $800-1,200 if caught early (cooler + flush); $3,500-5,500 if transmission damaged
Catastrophic Engine Oil Consumption and Piston Ring Failure
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Blue smoke from exhaust on startup or acceleration, Loss of power and rough idle, Check engine light with misfire codes, Engine knock or rod bearing noise if run low on oil
Fix: The VK56 engine in 2012-2014 NVs has a known defect where piston rings fail prematurely, leading to oil burning and eventually scored cylinders or spun bearings. Repair requires engine rebuild with new pistons, rings, and often cylinder honing (25-35 hrs), or short block replacement (20-28 hrs). Nissan extended warranty to 120k miles on some VINs but many 2014s fall outside coverage.
Estimated cost: $6,000-9,500 for rebuild; $8,000-12,000 for short block replacement with labor
Transmission Mount Failure
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Heavy clunk when shifting from park to drive or reverse, Vibration through floor and pedals at idle, Excessive drivetrain movement visible under throttle, Transmission tunnel heat complaints
Fix: The rear transmission mount (crossmember mount) deteriorates from heat and load, especially in cargo/high-GVWR use. Replacement is straightforward with transmission support (1.5-2.5 hrs depending on exhaust clearance). OEM mounts last longer than aftermarket in this application.
Estimated cost: $300-550
Fuel Filter Clogging and Fuel Pump Wear
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Hard starting or extended cranking when hot, Loss of power under load or uphill, Stalling or hesitation during acceleration, Fuel pressure below spec (should be 51 PSI)
Fix: The in-tank fuel filter and pump assembly can clog or wear, especially if fuel quality was poor. Requires tank drop and pump/filter assembly replacement (3-4 hrs). Some techs report the NV's large tank and frame routing makes this more labor-intensive than passenger vehicles.
Estimated cost: $650-1,100
Timing Chain Guide and Tensioner Wear
Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Rattling noise from front of engine on cold start that fades after 5-10 seconds, Check engine light with cam/crank correlation codes, Loss of power or rough running if chain has jumped, Metal particles in oil
Fix: The VK56 uses timing chains with plastic-backed guides that wear over time. If caught early (just noise), replace guides, tensioners, and chains (primary and secondary) with updated parts (10-14 hrs). If chain jumps, valve damage likely requires head work adding significant cost. Oil change intervals critical for prevention.
Estimated cost: $2,200-3,500 preventive; $5,000-8,000+ if valve damage occurred
Rear Axle Seal Leaks
Common · low severity
Typical onset: 60,000-100,000 mi
Symptoms: Gear oil dripping from rear wheel area or differential cover, Oil stains on inside of rear wheels, Whining or growling from rear end if fluid level drops critically
Fix: Pinion seal or axle shaft seals leak on high-mileage NVs, especially commercial use. Axle seal replacement requires pulling axle shafts (1.5 hrs per side). Pinion seal requires driveshaft removal and preload reset (2-3 hrs). Check for bearing wear while apart.
Estimated cost: $250-450 for axle seals; $400-650 for pinion seal
Owner tips
Check transmission cooler and consider external cooler bypass immediately on any used purchase — this single mod can save the transmission
Monitor oil consumption religiously; if burning more than 1 quart per 3,000 miles, budget for engine work soon
Use full synthetic 5W-30 and keep oil change intervals at 5,000 miles maximum to protect timing chain components
Inspect rear differential fluid level and condition every 30k miles — cheap insurance against seal leaks turning into bearing failures
If buying used, verify VIN against Nissan's oil consumption warranty extension (ended 2019 but shows problem history)
Buy only if oil consumption history is documented clean and transmission cooler has been addressed or bypassed; budget $3k-5k reserve for potential engine or trans work on anything over 80k miles — great utility but these two issues are deal-breakers if ignored.

AIR BAGS:FRONTAL:DRIVER SIDE:INFLATOR MODULE · 20V188000
2020-03-30
Nissan North America, Inc. (Nissan) is recalling certain 2012-2017 NV Cargo and NV Passenger Van, 2013-2015 Titan and Armada and 2011-2012 Infiniti QX56 vehicles. Due to a manufacturing issue, the air bag inflator may not function properly or may rupture during deployment.
Consequence: An inflator rupture may result in metal fragments striking the driver or other occupants resulting in serious injury or death.
Remedy: Nissan will notify owners, and dealers will replace the front driver air bag inflators, free of charge. The recall began May 7, 2020. Owners may contact Nissan customer service at 1-800-867-7669 or Infiniti customer service at 1-800-662-6200.
SEAT BELTS:REAR/OTHER · 14V419000
2014-07-10
Nissan North America, Inc. (Nissan) is recalling certain model year 2014 NV passenger vans manufactured March 14, 2014 to May 15, 2014, equipped with seat belt retractors from Faurecia Automotive Systems. The seat belt retractor bolts on the 2nd, 3rd, and 4th row removable seats may not be torqued to proper specification, or may be missing, on the affected vehicles. This can cause the seat belt anchor to not be secured properly.
Consequence: If the seat belt retractor bolts are not torqued to specification, or are missing, it may cause the seat belt anchor to not be secured properly. If this occurs, the belt may not properly restrain the seat occupant in the event of a crash increasing the risk of injury.
Remedy: Nissan will notify owners, and dealers will inspect the seat belt retractor bolt for the proper torque, and tighten if necessary, free of charge. The recall began in September 2014. Owners may contact Nissan customer service at 1-800-647-7261.
