The 2005 Murano pairs Nissan's solid VQ35DE V6 with the CVT transmission that became its Achilles' heel. Catastrophic CVT failures and internal engine damage from pre-cat breakup define this generation's reputation.
CVT Transmission Failure (Complete Internal Destruction)
Common · high severityTypical onset: 90,000-150,000 mi
Symptoms: Shuddering or jerking during acceleration, especially from stops, Whining or grinding noise from transmission, Loss of power or hesitation when accelerating, Check engine light with CVT-related codes (P0868, P1778), Sudden loss of forward or reverse gears
Fix: CVT rebuild rarely works long-term. Full replacement is standard: remove transmission (6-8 hours), install remanufactured unit, flush cooler lines. Many shops won't touch CVT rebuilds due to comeback rate.
Estimated cost: $3,500-5,500
Pre-Catalytic Converter Failure Leading to Engine Damage
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Metallic rattling noise from engine bay on cold starts, Loss of power and rough running, Check engine light with misfire codes and catalyst efficiency codes, Metal debris visible on oil pan magnetic drain plug, Catastrophic engine failure if pre-cat substrate breaks apart and enters cylinders
Fix: Pre-cats (integral to manifolds) disintegrate, sending ceramic chunks into cylinders, scoring walls and destroying rings. Requires complete engine rebuild or replacement (25-35 hours): head gaskets, pistons, rings, honing, possibly crankshaft work. Prevention: replace manifolds/pre-cats preemptively around 80k.
Estimated cost: $4,500-8,000
Transmission Oil Cooler Internal Leakage (RADIATOR OF DEATH - SMOD)
Common · high severityTypical onset: 70,000-110,000 mi
Symptoms: Milky or strawberry-colored transmission fluid (coolant contamination), Coolant reservoir level dropping without visible external leaks, Transmission slipping or delayed engagement after coolant intrusion, Engine overheating if transmission fluid enters cooling system
Fix: Internal cooler in radiator fails, mixing coolant and ATF—instant CVT death sentence. Requires radiator replacement (2-3 hours), CVT flush or replacement depending on contamination severity, external cooler installation recommended. Catch it early or you're buying a transmission too.
Estimated cost: $800-1,200 (radiator only), $4,000-5,500 (if CVT damaged)
Transmission Mounts Collapse
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking noise when shifting from Park to Drive/Reverse, Excessive vibration at idle, Visible transmission sag on inspection, Harshness when accelerating from stop
Fix: Hydraulic mounts fail frequently due to CVT weight and vibration. Front mount replacement requires supporting transmission (2-3 hours), rear mount slightly easier. Replace both at same time to avoid comeback.
Estimated cost: $400-700
Mass Airflow Sensor Contamination and Failure
Occasional · medium severityTypical onset: 70,000-120,000 mi
Symptoms: Rough idle and stalling, Poor fuel economy (3-5 mpg drop), Hesitation or stumbling during acceleration, Check engine light with P0100-P0104 codes
Fix: MAF sensor filament gets contaminated from oiled aftermarket filters or age. Clean with MAF cleaner first (0.3 hours), replace if cleaning doesn't resolve (0.5 hours). Use OEM sensor—aftermarket failures common.
Estimated cost: $150-250 (cleaning), $350-500 (replacement)
Steering Column Lock Actuator Failure
Occasional · high severitySymptoms: Vehicle won't start with 'Steering Lock Malfunction' message, Clicking noise from steering column when trying to start, Key won't turn or ignition won't engage, Intermittent no-start requiring multiple attempts
Fix: Electronic steering lock actuator seizes, preventing starts (subject to recall but many missed it). Emergency fix: tap steering column near lock with rubber mallet while turning key. Permanent repair requires actuator replacement (1.5-2 hours) under steering column.
Estimated cost: $300-600
Fuel Tank and Pump Assembly Corrosion
Occasional · medium severityTypical onset: 120,000+ mi
Symptoms: Fuel gauge reading erratically or stuck, Fuel smell around vehicle, Check engine light with fuel level sensor codes, Difficulty starting when tank below 1/4 full
Fix: Tank straps rust in salt states, fuel pump assembly corrodes. Pump replacement requires dropping tank (2.5-3 hours). Address straps simultaneously. Subject to recalls for tank cracking—check VIN history.
Estimated cost: $600-1,000
Hard pass unless you can verify pre-cat replacement, external trans cooler install, and recent CVT service with records—even then, budget $5k for inevitable CVT replacement.
