The 2009 Armada with the VK56DE V8 is a body-on-frame SUV sharing DNA with the Titan and Infiniti QX56. While generally robust, it suffers from catastrophic engine failures tied to a known oil galley gasket defect and transmission cooling issues that can destroy the 5-speed automatic.
Oil Galley Gasket Failure Leading to Catastrophic Engine Damage
Common · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Sudden loss of oil pressure at highway speeds, Metal shavings in oil during changes, Rod knock or bottom-end noise that appears suddenly, Oil starvation to cylinders 5-8 visible on teardown
Fix: The VK56DE has a known defect where internal oil galley O-rings fail, starving the right cylinder bank. Once symptoms appear, damage is done—requires complete engine rebuild or replacement. Short block replacement takes 18-24 hours; full rebuild with machine work adds another 8-12 hours. Many owners opt for reman longblocks.
Symptoms: Strawberry milkshake appearance in radiator or transmission fluid, Transmission slipping or no forward movement after radiator leak, Coolant level drops with no external leaks, Transmission overheating warning on dash
Fix: Factory radiator has an integral ATF cooler that fails internally, mixing coolant and transmission fluid—destroys the RE5R05A transmission within days. Requires replacement radiator with external ATF cooler conversion, full transmission flush or rebuild depending on contamination severity, plus all cooling system hoses. Transmission R&R is 6-8 hours, rebuild adds 12-16 hours if damaged.
Estimated cost: $3,500-8,500
Timing Chain Tensioner and Guide Wear
Occasional · high severity
Typical onset: 100,000-180,000 mi
Symptoms: Rattling noise on cold starts that quiets after 5-10 seconds, Engine rattle at idle when hot, Check engine light with VVT codes (P0011, P0021), Metal debris in oil pan during changes
Fix: Primary and secondary timing chains stretch, tensioners wear, and plastic guides fragment. If caught early (just noise), tensioners and guides can be replaced with engine in-vehicle—12-15 hours. If jumped timing occurs, expect bent valves requiring head work, adding another 18-24 hours total.
Estimated cost: $2,200-6,500
Front Lower Control Arm Bushing Failure
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking over bumps from front suspension, Steering wander and poor highway tracking, Uneven inner tire wear, Visible torn rubber bushings on inspection
Fix: Factory bushings are undersized for this heavy SUV's weight. Bushings separate from control arm, causing play. Nissan issued recall 13V-527 for some units. Replacement requires complete lower control arms (bushings aren't serviceable separately). Both sides take 3-4 hours including alignment.
Estimated cost: $800-1,400
Fuel Level Sending Unit Failure
Occasional · low severity
Symptoms: Fuel gauge reads empty when tank is full or vice-versa, Erratic gauge movement while driving, Gauge stuck at one position regardless of fuel added, Check engine light with P0463 fuel level sensor code
Fix: Sending unit float arm corrodes or resistance track fails. Covered under Nissan recall 12V-017 for certain VINs. Requires fuel tank drop and sending unit replacement—2.5-3.5 hours labor. Dealer should cover if recall applies; aftermarket units available if not.
Estimated cost: $450-750
Transmission Mounts Collapsing
Common · medium severity
Typical onset: 70,000-110,000 mi
Symptoms: Clunk when shifting from park to drive or reverse, Vibration at idle in gear, Visible engine/transmission movement when applying throttle in park, Drivetrain shudder during acceleration
Fix: Rubber transmission mounts deteriorate from heat and weight of the heavy RE5R05A transmission. Rear mount fails most often. Replacement of transmission mount takes 2-3 hours; many techs replace engine mounts simultaneously as they're similar age and wear pattern.
Estimated cost: $400-900
Owner tips
Install an external transmission cooler and bypass the radiator ATF cooler immediately—cheap insurance against the $8K mixing failure
Change engine oil every 3,500-4,000 miles with quality synthetic to extend oil galley gasket life; Nissan Ester oil recommended
Listen for ANY timing chain rattle and address immediately—stretched chains lead to jumped timing and bent valves
Inspect lower control arm bushings at every tire rotation; catch them before alignment goes out and eats tires
Keep transmission fluid changes on 30,000-mile intervals with Nissan Matic-S only—not a 'lifetime' fluid despite what the manual says
Buy only with documented proof of external ATF cooler install and recent oil analysis showing clean results—otherwise budget $10K for engine or transmission failure within 20,000 miles.

2010-05-20
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.

2010-03-03
NISSAN IS RECALLING CERTAIN MODEL YEAR 2005-2009 TITAN, ARMADA, AND INFINITI QX56 VEHICLES. THE INSTRUMENT PANEL FUEL GAUGE MAY INACCURATELY DISPLAY THAT THE VEHICLE STILL HAS SOME FUEL, TYPICALLY ABOUT ONE QUARTER TANK, WHEN THE FUEL TANK IS EMPTY.
Consequence: THIS COULD CAUSE THE VEHICLE TO RUN OUT OF GAS AND STALL ON THE HIGHWAY, WHICH COULD CAUSE A CRASH.
Remedy: DEALERS WILL REPLACE THE FUEL SENDER UNIT INSIDE THE FUEL TANK WITH A NEW IMPROVED SENDER CARD. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 22, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.

THE PIVOT PIN COULD SLIDE AND CAUSE THE BRAKE PEDAL TO PARTIALLY DISENGAGE FROM THE BRAKE PEDAL BRACKET.
Consequence: THE DRIVER WILL EXPERIENCE UNUSUAL AND NOTICEABLE LOOSENESS IN THE PEDAL AND A REDUCTION IN BRAKING FORCE INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT TO SEE IF THE PIVOT PIN HAD BEEN FORMED PROPERLY AND WILL REPLACE THE BRAKE PEDAL ASSEMBLY IF NECESSARY FREE OF CHARGE. THE SAFETY RECALL BEGAN ON MARCH 22, 2010. OWNERS MAY CONTACT NISSAN AT 1-800-647-7261.
