The 2004 Armada's VK56DE V8 is plagued by early piston/ring failure due to inadequate ring land design, leading to catastrophic oil consumption and engine rebuilds well before 150k miles. The transmission cooler also fails internally, contaminating ATF with coolant and destroying the 5-speed auto if not caught early.
Piston Ring Land Failure / Oil Consumption
Common · high severity
Typical onset: 80,000-140,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Blue smoke on startup or acceleration, P0300 random misfire or cylinder-specific misfire codes, Loss of power and rough idle as rings collapse
Fix: Ring lands crack due to weak design, especially on cylinders 5-8. Full engine rebuild or short block replacement required (18-24 labor hours). Many opt for reman long block swap.
Estimated cost: $4,500-7,500
Transmission Oil Cooler Failure (SMOD - Strawberry Milkshake of Death)
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Pink or milky transmission fluid on dipstick, Transmission slipping, delayed engagement, or harsh shifts, Coolant level drops without external leaks, Transmission overheating
Fix: Internal cooler in radiator ruptures, mixing coolant into ATF and destroying clutches/valve body. Requires radiator replacement, external cooler install, full ATF flush, often transmission rebuild (12-20 hours total if trans damaged).
Symptoms: Clunking over bumps from front suspension, Steering wander or vague on-center feel, Uneven or cupped tire wear on inside edge, Vibration during braking
Fix: OE bushings are weak rubber that tears and separates. Control arms typically replaced as assemblies since bushings aren't serviceable on most aftermarket parts (2.5-3.5 hours per side).
Estimated cost: $600-1,000 (both sides)
Transmission Mount Collapse
Occasional · medium severity
Typical onset: 90,000-150,000 mi
Symptoms: Clunk when shifting from Park to Drive or Reverse, Excessive driveline vibration at idle in gear, Visible sag or tearing of rubber mount body, Chassis shudder during acceleration
Fix: Rear transmission mount deteriorates from heat and load. Replacement requires supporting transmission (1.5-2 hours). Often done with engine mounts if they're original.
Estimated cost: $250-400
Timing Chain Guide and Tensioner Wear
Occasional · high severity
Typical onset: 120,000-180,000 mi
Symptoms: Rattling noise on cold start for 2-5 seconds, Timing chain noise (metallic whirring) from front of engine, Check engine light with cam/crank correlation codes (P0340, P0345), Rough idle or poor performance if chain has jumped
Fix: Plastic guides wear and tensioners lose tension. Requires front cover removal, chains, guides, tensioners replacement (10-14 hours). Critical to address before chain jumps and bends valves.
Estimated cost: $2,000-3,200
Fuel Gauge Sending Unit Failure
Occasional · low severity
Symptoms: Fuel gauge reads empty when tank has fuel, Erratic gauge movement or stuck at full, Fuel light stays on continuously, Gauge works intermittently over bumps
Fix: Sending unit contacts corrode or float arm breaks. Requires fuel tank drop and pump module replacement (2.5-3.5 hours). Common across Nissan trucks of this era.
Estimated cost: $450-700
Owner tips
Install aftermarket external transmission cooler immediately and bypass factory radiator cooler to prevent SMOD — this is non-negotiable preventive maintenance
Check oil level every fill-up after 80k miles; if consuming more than 1 quart per 2,000 miles, budget for engine work soon
Use quality full-synthetic 5W-30 and change every 5,000 miles to maximize timing chain component life
Inspect transmission fluid color monthly — any pink tint means immediate action needed before trans is destroyed
Only buy if engine has documented rebuild or confirmed low oil consumption; otherwise you're gambling on a $6k repair before 150k miles, and the trans cooler issue can strike anytime — budget accordingly or walk away.

NISSAN IS RECALLING CERTAIN MODEL YEAR 2004-2006 ARMADA, TITAN, INFINITI QX56 AND MODEL YEAR 2005-2006 FRONTIER, PATHFINDER AND XTERRA VEHICLES. THE INTELLIGENT POWER DISTRIBUTION MODULE (IPDM) ASSEMBLY CONTAINS AN ENGINE CONTROL MODULE (ECM) RELAY THAT HAS A DIODE FOR ELECTRICAL CURRENT NOISE REDUCTION. THE ECM RELAY MAY ALLOW SILICON VAPOR TO FORM AND, OVER TIME, THE SILICON EVAPORATES FROM THE DIODE MOLDING WHICH CAUSES SILICON OXIDE TO DEVELOP ON THE ECM RELAY CONTACT DUE TO ARCING.
Consequence: THIS COULD CAUSE ENGINE STALLING INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL REPLACE THE ECM RELAY INSIDE THE IPDM ASSEMBLY. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON DECEMBER 6, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

NISSAN IS RECALLING CERTAIN FRONT AND REAR LOWER LINKS, P/NOS. 54501ZQ00A, 54500ZQ00A, 551A1ZQ00A, 551A0ZQ00A , 54501EA00A, 54500EA00A, 551A1EA500, 551A0EA500, 54501ZR00A, AND 54500ZR00A, SOLD BETWEEN NOVEMBER 25, 2009 AND MAY 14, 2010 AS REPLACEMENT PARTS FOR MODEL YEAR 2004 THROUGH 2010 TITAN, ARMADA, AND QX56, AND MODEL YEARS 2005 THROUGH 2010 FRONTIER, XTERRA, AND PATHFINDER VEHICLES. THE LOWER CONTROL LINK ASSEMBLY HAS TWO CYLINDRICAL COLLARS FORMING THE INBOARD ATTACHMENT POINTS TO THE CHASSIS. DUE TO AN IMPROPER WELDING PROCESS SOME COLLARS MAY CONTAIN WELDS THAT DO NOT MEET STRENGTH SPECIFICATIONS.
Consequence: IF THE COLLAR WELD SEPARATES, THE VEHICLE HANDLING WILL DETERIORATE, POSSIBLY RESULTING IN A VEHICLE CRASH.
Remedy: NISSAN WILL NOTIFY OWNERS AND DEALERS WILL REPLACE ANY AFFECTED LOWER LINK FREE OF CHARGE. THE SAFETY RECALL BEGAN ON JULY 12, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

CERTAIN HOPKINS AFTERMARKET TRAILER BRAKE CONTROL CONNECTION HARNESSES SOLD FOR USE ON CERTAIN MODELS OF NISSAN VEHICLES WHICH ARE LISTED ABOVE. THE INTERNAL PART NUMBERS WITHIN HOPKINS ARE: 1010476025, 1040376025, 1110476025, 1170376025, 1290376025, 1010476035, 1040376035, 1110476035, 1170376035, AND 1290376035. A WIRE MAY HAVE BEEN PLACED IN AN INCORRECT POSITION IN THE ELECTRICAL CONNECTOR HOUSING. THIS RESULTS IN AN INCORRECT ROUTING OF WIRES BETWEEN THE TRAILER BRAKE CONTROLLER AND THE TOWING VEHICLE WIRING SYSTEM.
Consequence: THIS HARNESS WOULD RESULT IN POWER FROM THE TRAILER BRAKE CONTROLLER GOING TO THE TOWING VEHICLE DASH LIGHT CIRCUIT RATHER THAN THE TRAILER BRAKES. THIS RESULT WOULD BE THE LACK OF TRAILER BRAKING WHEN THE TOWING VEHICLE BRAKES WERE APPLIED. IT WOULD ALSO RESULT IN THE TOWING VEHICLES DASH LIGHTS BEING ACTIVATED WHEN THE VEHICLE BRAKES WERE APPLIED. THE FAILURE OF THE APPLICATION OF THE TRAILER BRAKE COULD RESULT IN REDUCED ABILITY TO STOP AND CONTRIBUTE TO A POSSIBLE CRASH.
Remedy: HOPKINS WILL NOTIFY OWNERS AND REPLACE THE ORIGINAL HARNESS WITH A REVISED HARNESS FREE OF CHARGE. THE RECALL BEGAN AUGUST 17, 2007. OWNERS CAN CONTACT HOPKINS AT 800-835-0129.
