The 2004 Murano pioneered Nissan's CVT in a midsize crossover, and that CVT (RE0F06A) is the platform's Achilles heel. The VQ35DE engine itself is solid but can suffer catastrophic bearing failure from oil starvation if the owner skips changes or runs low.
CVT Transmission Failure (RE0F06A)
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: Shuddering or jerking during acceleration, especially 15-40 mph, Whining or grinding noise from transmission, Loss of power, slipping, or sudden inability to move, Check engine light with P0868 (transmission fluid pressure) or P0731 (gear ratio codes)
Fix: CVT replacement is the only reliable fix once internal damage occurs. Rebuilt units run 12-16 labor hours for R&R. Fluid changes every 30k can delay but not prevent eventual failure on this generation.
Estimated cost: $3,500-5,500
Engine Bearing Failure (VQ35DE)
Occasional · high severityTypical onset: 100,000-150,000 mi
Symptoms: Knocking or ticking from lower engine, worsens with RPM, Metal shavings in oil or on drain plug magnet, Loss of oil pressure, oil pressure warning light, Sudden catastrophic failure with locked engine
Fix: Connecting rod and main bearings fail from oil sludge or low-level running. Requires full engine teardown or short block replacement, 18-24 hours labor. Some owners opt for used engine swap (10-12 hours) if block is scored.
Estimated cost: $4,000-7,000
Transmission Oil Cooler Failure / Coolant Cross-Contamination
Common · high severityTypical onset: 70,000-110,000 mi
Symptoms: Milky or strawberry-colored transmission fluid, Coolant looks oily or has transmission fluid mixed in, Transmission slipping or erratic shifting after cooler fails, Overheating transmission or engine
Fix: Factory CVT cooler is integrated into radiator; internal leak allows coolant and ATF to mix, destroying CVT. Requires radiator replacement, full CVT fluid flush (or CVT replacement if contamination went unnoticed), and coolant system flush. 8-10 hours if CVT survives, 16+ if it doesn't. Install external CVT cooler as preventive measure.
Estimated cost: $1,200-2,500 (if caught early); $4,500-6,500 (if CVT damaged)
Front and Rear Engine/Transmission Mounts
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Clunking or banging when shifting from Park to Drive or Reverse, Excessive vibration at idle or under acceleration, Engine/transmission visibly sagging or tilting, Harsh engagement into gear
Fix: Hydraulic mounts fail, especially rear transmission mount. Replace all three (front two engine, one rear trans) as a set. 3-4 hours labor. Delaying replacement accelerates CVT wear from misalignment.
Estimated cost: $600-1,000
Mass Airflow Sensor (MAF) and Intake Boot Cracks
Common · low severityTypical onset: 80,000-120,000 mi
Symptoms: Rough idle, stalling, or hesitation, Check engine light P0171/P0174 (lean codes) or P0101 (MAF range), Poor fuel economy, Idle surging or hunting
Fix: MAF sensor fails or intake boot between MAF and throttle body cracks, causing unmetered air. Clean MAF first; if no improvement, replace sensor. Check boot for cracks. 0.5-1.0 hour labor.
Estimated cost: $200-400
Fuel Pump and Fuel Filter Clogging
Occasional · medium severityTypical onset: 90,000-140,000 mi
Symptoms: Stalling or sputtering under load or at highway speed, Difficulty starting, extended cranking, Loss of power on acceleration, Check engine light P0171 (lean) or fuel trim codes
Fix: In-tank fuel pump fails or internal filter clogs. Requires tank drop, pump/filter/sending unit replacement. 3-4 hours labor. Use OE-quality pump; cheap aftermarket units fail quickly.
Estimated cost: $600-1,000
Alternator Failure
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: Battery warning light on dash, Dimming headlights or interior lights, Electrical accessories cutting out, No-start or battery repeatedly dies
Fix: Alternator voltage regulator or diodes fail. R&R is straightforward on VQ35DE, 1.5-2 hours. Subject of NHTSA recall for some VINs, check recall status first. Replace battery at same time if older than 4 years.
Estimated cost: $400-700
Buy only if CVT and oil cooler have already been replaced with external cooler added, or budget $4k-6k for inevitable CVT failure—engine is strong if oil-maintained, but this transmission kills resale value.
