The 2006 Murano with the VQ35DE V6 is a comfortable crossover with one catastrophic weakness: the CVT transmission and its cooling system fail with alarming regularity, often requiring complete replacement. Engine issues are also surprisingly common for this generation, particularly oil consumption leading to catastrophic internal damage.
CVT Transmission Failure
Common · high severityTypical onset: 80,000-130,000 mi
Symptoms: shuddering or juddering during acceleration, whining or grinding noise, delayed engagement when shifting to drive, transmission overheating warnings, complete loss of forward movement
Fix: CVT replacement is the typical outcome once symptoms appear. Nissan extended warranty to 120k miles on some units, but many fail just outside that window. Expect 8-10 hours labor for transmission R&R plus fluid and programming
Estimated cost: $3,500-5,500
Transmission Cooler Line Failure and Coolant Cross-Contamination
Common · high severityTypical onset: 60,000-100,000 mi
Symptoms: strawberry milkshake-colored transmission fluid, transmission slipping or erratic shifting, coolant level dropping, sweet smell from exhaust or coolant overflow
Fix: The CVT cooler inside the radiator fails, allowing coolant and ATF to mix. This destroys the CVT within days if not caught immediately. Requires radiator replacement, transmission flush or replacement, and all cooler lines. If contamination reached CVT clutches, full transmission replacement needed. 6-12 hours depending on transmission condition
Estimated cost: $1,200-5,000
Excessive Engine Oil Consumption Leading to Internal Damage
Common · high severityTypical onset: 90,000-150,000 mi
Symptoms: burning one quart per 1,000 miles or less, blue smoke from exhaust on startup or acceleration, rough idle, check engine light with misfire codes, catastrophic engine failure if oil level runs dry
Fix: VQ35DE engines in this era consume oil due to piston ring design and valve stem seal failure. Many owners don't check oil frequently enough, resulting in spun bearings, scored cylinders, or complete seizure. Proactive owners can limp along adding oil, but permanent fix requires engine rebuild or replacement. 20-30 hours for rebuild, 12-18 for used engine swap
Estimated cost: $4,000-7,000
Front Strut Mount Bearing Failure
Common · medium severityTypical onset: 70,000-110,000 mi
Symptoms: clunking noise over bumps, knocking sound when turning steering wheel, steering feels notchy or has dead spots, uneven tire wear on front
Fix: The upper strut mount bearings wear out and create noise and poor steering feel. Often misdiagnosed as ball joints or tie rods. Replace both front strut mounts with bearings. 2.5-3.5 hours labor for both sides with alignment
Estimated cost: $450-750
Catalytic Converter Failure (P0420/P0430)
Occasional · medium severityTypical onset: 100,000-150,000 mi
Symptoms: check engine light with catalyst efficiency codes, slight loss of power, sulfur/rotten egg smell, failed emissions test
Fix: The VQ35DE has three catalytic converters that can fail independently. Bank 1 and 2 main cats are integrated into manifolds (expensive OEM parts). Downstream cat is separate. Verify actual cat failure versus O2 sensor issues first. 3-5 hours labor depending on which cats need replacement
Estimated cost: $800-2,500
Fuel Pump Failure
Occasional · high severityTypical onset: 90,000-140,000 mi
Symptoms: no-start condition with cranking but no fire, intermittent stalling especially when hot, loss of power under load, whining noise from rear of vehicle
Fix: In-tank fuel pump assembly fails, leaving you stranded. Requires dropping the fuel tank for access. Use OEM or quality aftermarket only; cheap pumps fail quickly. 2.5-3.5 hours labor
Estimated cost: $600-950
Avoid unless under 60k miles with full service records and priced $2,000+ below market to account for imminent CVT failure — this generation Murano is a financial timebomb.
