What is the 2004-2015 Nissan Armada Radiator Internal Transmission Cooler Rupture Mixing Coolant Into ATF?

The TA60 radiator has the automatic transmission cooler built into the bottom tank, with coolant and ATF separated only by a thin internal wall. That wall cracks with age and thermal cycling, letting coolant push into the transmission circuit. The resulting pink, milky ATF - owne… Repairs typically run $600-$5,500. Severity: high.

What is the 2004-2006 Nissan Armada IPDM ECM Relay Failure Causing Engine Stalling (Recall 10V517000)?

Nissan recalled 2004-2006 Armada full-size SUVs because of a defect inside the Intelligent Power Distribution Module (IPDM). The IPDM assembly houses an engine control module (ECM) relay whose diode includes a silicon molding used to suppress electrical current noise. On affected… Severity: high.

What is the 2004-2008 Nissan Armada Delta Stroke Sensor / ABS Actuator Fault Causing Premature ABS Activation (C1179)?

The TA60 brake booster carries an integral delta stroke sensor that reports pedal travel versus booster assist to the ABS/VDC control unit. When that sensor drifts or the ABS actuator software misinterprets it, the system thinks the driver has made a panic input and cycles ABS at… Repairs typically run $400-$2,200. Severity: high.

What is the 2004-2015 Nissan Armada Transfer Case Shift Actuator Motor / ATP Sensor Failure Leaving 4WD Inoperative?

The TA60 all-mode transfer case is shifted by an electric actuator motor with an internal position (ATP) sensor. Grease hardening, water intrusion at the connector, and worn sensor contacts make the transfer case control module lose position feedback, so the truck refuses to leav… Repairs typically run $300-$1,400. Severity: medium.

What is the 2004-2015 Nissan Armada Exhaust Manifold Cracking (Both Banks)?

The VK56DE V8 in the first-gen Armada is notorious for cracked exhaust manifolds. Both driver and passenger side manifolds develop cracks from thermal cycling, causing an exhaust leak that sounds like a ticking noise on cold start. The cracks worsen over time and can cause check… Repairs typically run $500-$1,500. Severity: medium.

What is the 2004-2015 Nissan Armada Rear Air Suspension Compressor and Airbag Failure?

First-generation Armadas equipped with the rear auto-leveling air suspension suffer from compressor burnout and air spring bag leaks. The compressor runs excessively to compensate for leaking airbags, eventually overheating and failing. Once the system fails, the rear sags signif… Repairs typically run $300-$1,200. Severity: medium.

What is the 2004-2015 Nissan Armada HVAC Air-Mix (Blend) Door Actuator Gear Stripping?

The dash-mounted air-mix and mode door actuators use small plastic gear trains driven by a motor with a position feedback potentiometer. The gear teeth strip or the actuator jams against a binding door, and the motor then hunts back and forth - owners describe a rapid clicking or… Repairs typically run $150-$900. Severity: medium.

What is the 2004-2015 Nissan Armada Overhead Console and Sunglass Holder Mounting Bosses Cracking and Dropping?

The full-length overhead console on the TA60 is bonded and screwed to thin plastic mounting bosses. Sustained cabin heat softens the adhesive and embrittles the plastic, and the two small screws under the sunglass holder tear out of their bosses. The console then sags in the midd… Repairs typically run $50-$1,300. Severity: low.

What is the 2004-2015 Nissan Armada Timing Chain Guide and Tensioner Wear Causing Cold-Start Front-of-Engine Rattle?

The VK56 timing chain system uses plastic-faced guides and an oil-pressure-fed hydraulic tensioner. The feed passage to the tensioner is very small and gets restricted by sludge or debris on trucks run on stretched oil-change intervals, so the tensioner loses pressure and the cha… Repairs typically run $1,800-$3,500. Severity: high.
